第一章   概  述

Chapter 1 Summarize

辊压机是八十年代中期在国际上发展起来的新型粉碎设备。以它为主组成的挤压粉磨新工艺在节能方面有着显著的效果,受到国际水泥界的普遍重视,成为发展粉磨工艺的一项新技术。

Roller press is a new type of crushing equipment developed internationally in the mid-1980s. The new extrusion grinding technology mainly composed of it has a significant effect in energy saving, and it has been widely valued by the international cement industry and has become a new technology for the development of grinding technology.

该机应用高压料层粉碎能耗低的原理,采用单颗粒粉碎群体化低工作方式。脆性物料经过高压挤压(该机在压力区的压力约为150Mpa)使物料的粒度迅速减小,小于0.08mm的细粉含量达到20～30%,小于2mm的物料达到70%以上,并且在所有经挤压的物料中存在有大量的裂纹,使物料在下一个工序中粉磨时,所需的能耗大幅度降低。根据国外有关资料的报导和我们已取得的实际使用经验,采用此设备的粉磨系统比未采用该设备的粉磨系统可增产50～200%。单产电耗可降低20～35%。并且由于磨辊的磨损小,使得单位磨耗大为降低,同时设备工作的噪音、粉尘等均较小,改善了工人劳动环境,充分显示出其卓越的经济效益和社会效益。

The machine applies the principle of low energy consumption for high-pressure material crushing, and adopts single-particle crushing and grouping low working mode. Brittle materials undergo high-pressure extrusion (the pressure of the machine in the pressure zone is about 150Mpa) to rapidly reduce the particle size of the material. The content of fine powder less than 0.08mm reaches 20-30%, and the material less than 2mm reaches more than 70%. There are a large number of cracks in all extruded materials, which greatly reduces the energy consumption when the materials are ground in the next process. According to the reports of relevant foreign materials and the actual use experience we have obtained, the grinding system with this equipment can increase the output by 50-200% compared with the grinding system without this equipment. Power consumption per unit of production can be reduced by 20 to 35%. And because of the small wear of the grinding roller, the unit wear is greatly reduced. At the same time, the noise and dust of the equipment are relatively small, which improves the working environment of workers and fully demonstrates its excellent economic and social benefits.

辊压粉碎机的主体是两个相向转动的辊子。脆性物料由输送设备,送入装有称重传感器的称重仓,而后通过辊压机的进料装置,进入两大小相同,相对转动的辊子之间,由辊子一面将物料拉入辊隙中,一面以其间的高压将物料压成密实的物料饼,最后从辊隙中落下,经出料斗,由输送设备提出。由下一工序对物料饼作进一步的分散或粉磨。

The main body of the roller crusher is two rollers rotating towards each other. The brittle material is sent by the conveying equipment to the weighing bin equipped with the weighing sensor, and then passes through the feeding device of the roller press, and enters between two relatively rotating rollers of the same size, and the material is pulled into the roller gap by the roller side. On one side, the material is pressed into a compact material cake with the high pressure in between, and finally falls from the roll gap, passes through the discharge hopper, and is lifted by the conveying equipment. From the next process, the material cake is further dispersed or ground.  

第二章  结构简介

Chapter 2 Structure introduction

辊压粉碎机结构较为复杂,载荷很大,系统、部件较多。为了更好地使用该设备,必须对其各个部件和系统必要的了解。

The structure of the roller crusher is complex, the load is large, and the system and components are many. In order to use the equipment better, it is necessary to understand the various components and systems.

该设备是由轴系、主机架,进料装置、传动系统、液压系统、润滑系统、辊罩、检测系统组成。见辊压机总图。

The equipment is composed of shaft system, main frame, feeding device, driving system, hydraulic system, lubrication system, roller cover, and detection system. See the general drawing of the roller press.

两磨辊分别为固定辊与活动辊,活动辊安装于机架内腔的导轨上,固定辊固装于机架立柱上。进料装置、液压系统、润滑系统均安装在主机架上。主减速机—行星减速机用缩套联轴器悬挂在主轴上,由扭矩平衡装置平衡其输出扭矩,主电机的驱动力矩通过十字轴式万向节传动轴传给行星减速机。

The two grinding rollers are respectively fixed roller and movable roller. The movable roller is installed on the guide rail in the inner cavity of the machine frame, and the fixed roller is fixedly installed on the column of the machine frame. The feeding device, hydraulic system and lubrication system are all installed on the main frame. The main reducer-planetary reducer is suspended on the main shaft with shrink sleeve coupling, and its output torque is balanced by torque balance device. The driving torque of the main motor is transmitted to the planetary reducer through the cross shaft universal joint drive shaft.

轴系分两套,其中一套是固定不动的,即固定辊轴系,另一套则是可以在机架内腔作水平方向往复移动的,即移动辊轴系。两磨辊间对物料形成的高压是由液压系统中的液压缸产生的,当无物料通过时,液压缸产生的力由移动辊轴承座经中间架传给固定辊轴承座。不管有无物料通过磨辊,挤压粉碎力均在机架上被平衡,基本不传到基础上。该设备中的液压缸与蓄能器组成一液压弹簧,保持一较恒定的挤压粉碎力,同时兼有安全保护功能。主电机采用交流异步电机,整机采用微机控制。

The shaft system is divided into two sets, one of which is fixed, that is, the fixed roller shaft system, and the other is capable of reciprocating horizontally in the inner cavity of the frame, that is, the moving roller shaft system. The high pressure on the material formed between the two grinding rollers is generated by the hydraulic cylinder in the hydraulic system. When no material passes through, the force generated by the hydraulic cylinder is transmitted from the moving roller bearing seat to the fixed roller bearing seat via the intermediate frame. Regardless of whether the material passes through the grinding roller, the squeezing and crushing force is balanced on the frame, and basically not transmitted to the foundation. The hydraulic cylinder and the accumulator in the equipment form the hydraulic spring, which maintains a relatively constant squeezing and crushing force, and also has a safety protection function. The main motor adopts AC asynchronous motor, and the whole machine adopts microcomputer control.

现将该设备中主要部件简介如下:

The main components of the equipment are introduced as follows:

一．主轴轴系

1. shaft system of main shaft

该部件由堆焊有一定厚度耐磨材料的磨辊主轴、双列球面滚子轴承,轴承座以及内、外轴承端盖、定位环、端面热电阻、水冷系统等零部件组成。见轴系装配示意图。

The component consists of grinding roller main shaft with a certain thickness of wear-resistant material, double-row spherical roller bearings, bearing seats, inner and outer bearing end covers, locating rings, end face thermal resistance, water cooling system and other parts. See the shaft system assembly drawing.

主轴采用分体式,由轴体和轴套两部分组成,轴套表面堆焊了一层耐磨层,在耐磨层磨损后可在其上直接进行补焊修复,若轴套使用到无法修复的程度,则可更换一新轴套。主轴两轴承支承处,均为圆锥段,使主轴承的拆卸可借助于超高压油泵进行,便于检修更换。

The main shaft adopts split type and consists of two parts: the shaft body and the shaft sleeve. The surface of the shaft sleeve is welded with a wear-resistant layer. After the wear-resistant layer is worn out, it can be directly repaired by welding. If the sleeve is used to the extent that it cannot be repaired, it can be replaced with a new sleeve. The two bearing supports of the main shaft are both tapered sections, so that the main bearing can be disassembled with the aid of an ultra-high pressure oil pump, which is convenient for maintenance and replacement.

主轴承采用具有自动调心功能的双列球面滚子轴承。该轴承具有承载能力大,寿命长的特点,并采用智能干油润滑,保证其具有良好的润滑条件。

The main bearing adopts the double row spherical roller bearing with self-aligning function. The bearing has the characteristics of large carrying capacity and long life, and uses intelligent dry oil lubrication to ensure good lubrication conditions.

端面热电阻是用以检测主轴承工作温度的,它紧贴在主轴承的外圈上,保证连续检测,报警,控制主轴承温度。

The end surface thermal resistance is used to detect the working temperature of the main bearing. It is closely attached to the outer ring of the main bearing to ensure continuous detection, alarm and control the main bearing temperature.

水冷系统是用来降低主轴及轴承的工作温度,从而使轴系能稳定地连续运行。

The water cooling system is used to reduce the working temperature of the main shaft and bearings, so that the shafting system can run stably and continuously.

二．主机架

2. main frame

主机架是整个挤压粉碎机的基础, 挤压粉碎力由其承受。为便于减轻重量全部采用焊接结构,由上、下横梁、左、右立柱、承载销、定位销、导轨及联接螺栓组等组成。见主机架装配示意图。上、下横梁、左、右立柱均在焊接后作了整体退火处理,以消除其焊接应力。

The main frame is the foundation of the entire extrusion crusher, and the crushing force is borne by it. In order to reduce the weight, all welded structures are adopted, which are composed of upper and lower beams, left and right columns, bearing pins, positioning pins, guide rails and connecting bolt groups. See the main frame assembly drawing. The upper and lower beams, the left and right columns are all annealed after welding to eliminate the welding stress.

上、下横梁采用工字型结构,具有较大的刚度, 左、右立柱采用工字型与箱型结构相结合的结构,同样具有较高的刚度,使整个机架可连接成为一个刚性的整体。

The upper and lower beams adopt I-shaped structure, which has greater rigidity. The left and right columns adopt the structure that combines I-shaped and box-shaped structures, which also have high rigidity, so that the entire frame can be connected to become a rigid overall.

承载销主要起到将立柱上所受的粉碎力传递到上、下横梁上去的作用。在安装时应注意其标记。

The load-bearing pin mainly plays the role of transmitting the crushing force on the column to the upper and lower beams. Pay attention to its markings during installation.

定位销的主要作用是用于确定两侧上、下横梁的中心距。

The main function of the positioning pin is to determine the center distance of the upper and lower beams on both sides.

导轨是作为活动辊轴承座的导向装置而设置的,两侧的轨宽度有所不同,靠近传动侧的导轨应宽些。

The guide rail is set as the guide device of the movable roller bearing seat. The width of the rail on both sides is different, and the guide rail near the driving side should be wider.

螺栓组是确保机架联接的关键所在。因此该高强度螺栓不可用普通螺栓代用,并且在拧紧时应控制拧紧力矩。

The bolt group is the key to ensure the frame connection. Therefore, the high-strength bolts cannot be substituted with ordinary bolts, and the tightening torque should be controlled when tightening.

三．进料装置

3. feeding device

进料装置是保证物料能均匀,定量地进入压力区,并使物料受到良好挤压的一个重要装置。在工作中,物料始终充满整个进料装置,由其导向进入磨辊的压力区。

The feeding device is an important device to ensure that the materials can enter the pressure zone uniformly and quantitatively, and make the materials well squeezed. During work, the material always fills the entire feeding device and is guided by it into the pressure zone of the grinding roller.

进料装置由进料筒、闸板、下侧板、支架、丝杆、连杠、电机减速机等组成，详见进料装置装配随机部件图。

The feeding device is composed of the feeding tube, gate plate, the lower side plate, support, screw rod, connecting rod, and motor reducer. For details, please refer to the random parts assembly drawing of the feeding device.

在侧挡板的下端,既在压力区的磨损严重部位设置了高硬度的硬质合金材料。这样可以减小磨损,提高被挤压物料的挤压质量。

At the lower end of the side baffle, the high-hardness cemented carbide material is set in the severely worn parts of the pressure zone. This can reduce wear and improve the extrusion quality of the material being extruded.

由闸板、丝杆、连杠、电机减速机组成的杠杆式节能进料装置，由电机减速机来控制丝杆，通过连杠来控制闸板的开口大小，从而能达到控制处理量的作用。

The lever-type energy-saving feeding device composed of gate plate, screw rod, connecting rod, and motor reducer. The screw rod is controlled by the motor reducer, and the opening of the gate is controlled by the connecting rod, so as to achieve the effect of controlling the processing capacity. .

侧板顶紧装置用以控制侧挡板与磨辊端面的间隙,该装置是由支架、顶紧螺杆、蝶形弹簧及弹簧座等组成。

The side plate tightening device is used to control the gap between the side baffle plate and the end surface of the grinding roller. The device is composed of bracket, tightening screw, butterfly spring and spring seat.

通过顶紧螺杆可以调节侧挡板下端位置与磨辊端面的间隙。调节压板可以对蝶形弹簧的顶紧力作调整,使侧挡板在正常工作时保证与磨辊端面有适当的间隙,减小磨辊端面的漏料。

The gap between the lower end of the side baffle and the end surface of the grinding roller can be adjusted by tightening the screw. The adjusting pressure plate can adjust the tightening force of the butterfly spring, so that the side baffle can ensure a proper gap with the end face of the grinding roller during normal operation, and reduce the material leakage of the end face of the grinding roller.

四．主电机和传动系统

4. main motor and driving system

主电机是整套辊压机主动力源。采用两台高压三相异步电动机,用户可自购或委托制造商配套。

The main motor is the main power source of the complete roller press. Two high-voltage three-phase asynchronous motors are used, which can be purchased by the user or commissioned by the manufacturer.

传动系统采用国际上先进的行星减速器悬挂传动装置。通过缩套联轴器将行星减速器的输出轴刚性地固定在磨辊主轴上(见主轴联接图)。减速器的安装定位基础为磨辊主轴,并且减速器可以随主轴作水平移动。减速器的输出扭矩,由扭矩支承装置(见扭矩支承装置示意图)来平衡。扭矩支承包括一个四连杆机构和一个弹性系统。该扭矩支承可以满足活动辊的水平移动,同时起到均载、吸振和缓冲的作用,可以使加工、安装精度降低。四连杆机构中的所有铰接点均采用带密封圈的关节轴承,适应性强。弹性系统中的弹性元件采用具有轴向尺寸小,刚度系数大的蝶形弹簧。在设备工作中,可以通过调整装置,调节其弹簧的顶紧力,使弹性系统适应设备负载的状况,主电机与行星减速器之间使用万向节传动轴联接。由于该万向节传动轴设置在高速端,使其本身所需传递的扭矩相对较小,转速高。并且所用的十字轴万向节传动轴具有传动效力高、传递扭矩大、传动平稳、润滑条件好、节点倾角大等特点。

The driving system adopts the international advanced planetary reducer suspension driving device. The output shaft of the planetary reducer is rigidly fixed on the main shaft of the grinding roller through the shrink sleeve coupling (see the main shaft connection drawing). The installation and positioning basis of the reducer is the grinding roller main shaft, and the reducer can move horizontally with the main shaft. The output torque of the reducer is balanced by the torque support device (see the schematic drawing of the torque support device). The torque support includes one four-bar linkage and an elastic system. The torque support can meet the horizontal movement of the movable roller, and at the same time has the functions of load balancing, vibration absorption and buffering, and can reduce the processing and installation accuracy. All articulation points in the four-bar linkage mechanism adopt joint bearings with sealing rings, which is highly adaptable. The elastic element in the elastic system adopts butterfly springs with small axial size and large stiffness coefficient. In the equipment work, the tensioning force of the spring can be adjusted by the adjusting device, so that the elastic system can adapt to the condition of the equipment load. The main motor and the planetary reducer are connected by the universal joint drive shaft. Because the universal joint drive shaft is arranged at the high-speed end, the torque required to transmit by itself is relatively small and the speed is high. And the cross-shaft universal joint drive shaft used has the characteristics of high driving efficiency, large transmission torque, smooth transmission, good lubrication conditions, and large node inclination.

传动系统中所用到的缩套联轴器为一非标配套件,它由圆锥缩套、两个收缩盘,高强度螺栓组和防尘圈等组成。其工作原理是:拧紧高强度螺栓,使圆锥缩套紧压减速器的中空轴,并使其发生弹性变形,紧抱在磨辊主轴轴颈上,利用其间正压力所产生的磨擦力来起到传递扭矩和减速器定位的功能。

The shrink sleeve coupling used in the driving system is the non-standard accessory. It consists of the round tapered shrink sleeve, two shrink disks, the high-strength bolt group and the dust ring. Its working principle is: Tighten the high-strength bolts to make the round tapered shrink sleeve compress the hollow shaft of the reducer, and make it elastically deform, tightly hug the main shaft journal of the grinding roller, and the friction force generated by the positive pressure is used to transmit torque and reducer positioning.

五．液压系统

5. hydraulic system

液压系统是为磨辊提供所需的挤压粉碎力而设置的,其主要作用是液压弹簧,兼有液压保护功能。它的性能直接影响到挤压粉碎物料的质量和设备的安全。

The hydraulic system is set up to provide the required squeezing and crushing force for the grinding roller. Its main function is hydraulic spring, which also has hydraulic protection function. Its performance directly affects the quality of crushed materials and the safety of equipment.

该系统由泵站,阀台和油缸三大部分组成(见液压系统图)。油缸直接安装在机架上，阀台、泵站集成在油箱上，然后通过管路连接起来。

The system consists of three parts: pump station, valve table and oil cylinder (see hydraulic system drawing). The oil cylinder is directly installed on the frame, and the valve table and pump station are integrated on the oil tank, and then connected by pipelines.

泵站是提供液压油泵,主要由油泵、油泵电机、溢流阀、压力表及滤油器等组成。该泵站的滤油器与加压主油路串联布置,使液压油经过滤油器过滤后进入主油路,以避免因杂质进入主油路可能造成的系统元件的堵塞、系统压力可根据操作需要无级调节。可无级调节控制系统所需的压力。滤油器上附有压差发讯装置,当滤油器滤筒堵塞,两边压差达到一定值时发出报警信号,通知操作人员清洗或更换滤筒。阀台部分是液压系统的主油路和控制油路,由两只大容量蓄能器和电磁溢流阀等组成。在工作时,四只主油缸通过大直径管路与两只蓄能器相连通,使得它们之间的压力始终相同,油缸的动态特性灵敏,流量大的特点,磨辊间一旦进入异物,系统压力升高时,它能及时打开卸压,保护主机设备。该溢流阀即可液控,又可电控。在调试和处理意外事故时,可以按动电钮卸压或调整压力。阀台上另设置有压力传感器和电接点压力表。可以通过压力传感器,将压力系统压力信号输给主控制室和控制柜,与主机联锁,也便于操作人员观察操作。电接点压力表主要是控制液压系统压力的上、下限。控制泵站油泵电机的启闭。

The pumping station provides hydraulic oil pumps, which are mainly composed of oil pumps, oil pump motors, overflow valves, pressure gauges and oil filters. The oil filter of the pump station is arranged in series with the pressurized main oil circuit, so that the hydraulic oil enters the main oil circuit after being filtered by the oil filter. In order to avoid the blockage of system components that may be caused by impurities entering the main oil circuit, the system pressure can be steplessly adjusted according to operation needs. The pressure required by the control system can be steplessly adjusted. The oil filter is equipped with the pressure difference signaling device. When the oil filter cartridge is blocked and the pressure difference on both sides reaches a certain value, an alarm signal will be issued to notify the operator to clean or replace the filter cartridge. The valve table is the main oil circuit and control oil circuit of the hydraulic system, which is composed of two large-capacity accumulators and an electromagnetic overflow valve. When working, the four main cylinders are connected to the two accumulators through large-diameter pipelines, so that the pressure between them is always the same. The dynamic characteristics of the cylinders are sensitive and the flow rate is large. Once foreign matter enters the grinding roller room, when the system pressure rises, it can open the pressure relief in time to protect the main equipment. The overflow valve can be controlled hydraulically and electrically. When debugging and handling accidents, you can press the button to relieve or adjust the pressure. The pressure sensor and the electric contact pressure gauge are additionally arranged on the valve table. The pressure signal of the pressure system can be transmitted to the main control room and the control cabinet through the pressure sensor, and it is interlocked with the main machine, which is also convenient for the operator to observe and operate. The electric contact pressure gauge mainly controls the upper and lower limits of the hydraulic system pressure. Control the opening and closing of the oil pump motor of the pump station.

四只油缸直接作用于活动辊轴承座上,为磨辊提供适当的挤压粉碎力。油缸作用力可通过油路控制系统的转换使其作用于单边轴承座或双边轴承座,当磨辊分边动作时,由位移传感器对两轴承座的水平位移进行检测控制。油缸由缸体、活塞、端盖、耐磨环和密封圈组成。见油缸装配示意图,该油缸为双作用缸,这样一旦设备的进料系统发生故障。可以及时用油缸将活动辊拉回,增大辊隙,排除故障。

The four oil cylinders directly act on the bearing seat of the movable roller to provide proper crushing force for the grinding roller. The force of the oil cylinder can act on the single-sided bearing seat or the double-sided bearing seat through the conversion of the oil circuit control system. When the grinding roller is separated, the horizontal displacement of the two bearing seats is detected and controlled by the displacement sensor. The oil cylinder is composed of cylinder body, piston, end cover, wear ring and sealing ring. See the cylinder assembly drawing, the cylinder is the double-acting cylinder, so that once the equipment's feeding system fails, the movable roller can be pulled back with the oil cylinder in time to increase the gap and eliminate the fault.

在油缸活塞杆的端面,设置了一环面压头,以防止因移动辊轴线偏斜时,给液压缸附加径向载荷。

An annular pressure head is arranged on the end surface of the piston rod of the oil cylinder to prevent additional radial load to the hydraulic cylinder when the axis of the moving roller is deflected.

六．润滑系统

6. lubrication system

润滑系统用于主轴承的润滑,密封以及活动辊轴承座的润滑,该套润滑系统能适应多粉尘的工作环境,可保证主轴承和活动辊轴承座在良好的润滑状况下工作。

The lubrication system is used for the lubrication and sealing of the main bearing and the lubrication of the movable roller bearing seat. The lubrication system can adapt to the dusty working environment and can ensure that the main bearing and the movable roller bearing seat work under good lubrication conditions.

该系统分为几个部分：控制系统、电动加油泵、电动润滑泵电磁给油器、给油管、控制及信号线路。

The system is divided into several parts: control system, electric fuel pump, electric lubrication pump electromagnetic feeder, feed oil pipe, control and signal circuit.

该系统的控制部分可以控制电动加油泵、电动润滑泵启停，电磁给油器的运行；根据现场设备的各个润滑点的使用情况，控制电磁给油器的开启、关闭，实现控制润滑点的供油。电磁给油器上安装接近开关监测润滑点的运行状态和循环次数，将信息反馈给控制系统。

The control part of the system can control the start and stop of the electric refueling pump, the electric lubrication pump, and the operation of the electromagnetic oil feeder; according to the usage of each lubrication point of the field equipment, control the opening and closing of the electromagnetic oil feeder to realize the control of lubrication point oil supply. The proximity switch is installed on the electromagnetic oil feeder to monitor the operating status and cycle times of the lubrication point, and feedback the information to the control system.

控制系统共有三种控制方式：单机、自动和远程。

The control system has three control modes: stand-alone, automatic and remote.

（1）单机是指该干油润滑系统中的加油泵、润滑泵和电磁给油器可以在触摸屏上单独任意启动，之间没有任何的联锁关系。该控制方式主要用于系统的调试和检修。

(1) Stand-alone means that the refueling pump, lubrication pump and electromagnetic oil feeder in the dry oil lubrication system can be started independently on the touch screen without any interlocking relationship. This control method is mainly used for system debugging and maintenance.

（2）自动是指在触摸屏上实现该系统的自动启动、自动停止。加油泵、润滑泵和电磁给油器按照连锁关系运行：

(2) Automatic refers to the realization of automatic start and automatic stop of the system on the touch screen. The oil pump, lubrication pump and electromagnetic oil feeder operate in a chain relationship:

1）加油泵：当系统自动运行以后，若油箱液位低于下限，则加油泵自动启动，液位高于上限，加油泵自动停止；

1) Fuel pump: After the system runs automatically, if the fuel tank level is lower than the lower limit, the fuel pump will automatically start, and if the liquid level is higher than the upper limit, the fuel pump will automatically stop;

2）润滑泵和电磁给油器：润滑泵的运行状态主要由电磁给油器决定，只要有一个电磁给油器得电向润滑点供油，则润滑泵就要处于运行状态，只有当所有电磁给油器均失电，润滑泵在运行20S才停止。每个电磁给油器由循环次数和循环时间决定其工作与否，在电磁给油器工作以后，系统开始计数，当电磁给油器的循环次数（电磁阀的得失电次数）达到设定值以后，电磁阀立刻自动失电，停止向润滑点供油，进入循环间歇时间；间歇时间结束后，对应电磁给油器进入工作状态。

2) Lubrication pump and electromagnetic oil feeder: The operating state of the lubrication pump is mainly determined by the electromagnetic oil feeder. As long as one electromagnetic oil feeder is energized to supply oil to the lubrication point, the lubrication pump must be in operation. The electromagnetic oil feeders are all de-energized, and the lubrication pump stops after running for 20 seconds. Each electromagnetic oil feeder is determined by the number of cycles and cycle time whether it is working or not. After the electromagnetic oil feeder is working, the system starts to count. When the number of cycles of the solenoid oil feeder (the number of power gains and losses of the solenoid valve) reaches the set value, the solenoid valve will automatically lose power immediately, stop supplying oil to the lubrication point, and enter the cycle intermittent time; after the intermittent time is over, the corresponding electromagnetic oil feeder enters the working state.

（3）远程是指设备由来自中控室的驱动信号控制其启动、停止，系统接收远程连锁信号、反馈故障信号。处于远程控制方式时，设备的运行过程和自动控制方式时相同。

(3) Remote means that the equipment is controlled to start and stop by the drive signal from the central control room, and the system receives remote interlock signals and feedback fault signals. When in remote control mode, the operation process of the equipment is the same as in automatic control mode.

该系统可以完全实现全自动润滑。并能手动/自动切换功能。每点供油量由时间控制现场任意设定，性能可靠、技术先进，是理想的电脑程控润滑系统，详细资料请查阅润滑系统使用说明书。

The system can fully realize fully automatic lubrication. And can manually/automatically switch function. Each point of oil supply is arbitrarily set by the time control site, with reliable performance and advanced technology. It is an ideal computer-controlled lubrication system. For details, please refer to the lubrication system manual.

七．检测系统

7. detecting system

检测系统作为检测控制各个信号和参数而分布在各系统中。由检测元件检测出来的信号,实现各系统间的联锁,指示和报警。实现设备的自动控制。

The detection system is distributed in each system as detection and control of various signals and parameters. The signal detected by the detection element realizes the interlocking, indication and alarm between the systems. Realize the automatic control of equipment.

1.两磨辊间的辊隙检测

1. Roll gap detection between two grinding rolls

辊隙检测采用两只感应式位移传感器,分别设置在活动辊的两轴承座上,通过该传感器可以随时反映出两磨辊的辊隙,也即反映出物料饼的厚度。当两轴承座移动不均匀时,也可反映出偏差的大小。当两轴承座中之一或两轴承座同退至设定的最大位移时,即发出报警,并联锁停主电机,保证设备安全。

Roll gap detection uses two inductive displacement sensors, which are respectively set on the two bearing seats of the movable roller. The sensor can reflect the gap of the two grinding rollers at any time, that is, reflect the thickness of the material cake. When the two bearing seats move unevenly, the deviation can also be reflected. When one of the two bearing seats or both bearing seats retract to the set maximum displacement, an alarm is issued and the main motor is locked in parallel to ensure the safety of the equipment.

2.主轴承温度检测

2. Main bearing temperature detection

主轴承温度检测用端面铂热电阻。每个轴承分别检测。端面热电阻紧帖在轴承的外圈上,随时检测、反映主轴承的工作温度。当工作温度达到设定的最大值时,即发出报警,通知操作人员。

The end face platinum thermistor is used for main bearing temperature detection. Each bearing is tested separately. The thermal resistance of the end face is tightly attached to the outer ring of the bearing to detect and reflect the working temperature of the main bearing at any time. When the working temperature reaches the set maximum value, an alarm is issued to notify the operator.

3.液压系统压力检测

3. Hydraulic system pressure detection

液压系统压力检测采用压力传感器。该传感器将信号检测出传至主机控制柜,当系统压力超过所设定的最大系统压力时,即发出报警、并随即停止主传动电机。

Pressure sensor is used for hydraulic system pressure detection. The sensor detects the signal and transmits it to the main machine control cabinet. When the system pressure exceeds the set maximum system pressure, an alarm is issued and the main drive motor is stopped immediately.

4.润滑系统工作检测

4. Lubrication system work detection

润滑系统工作检测采用接近开关。该接近开关安装在系统分油器上,当分油器正常工作时, 接近开关每隔一相同的时间动作指示一次,当某一油路阻塞时,则接近开关始终不动作。但必须注意的是,分油器或者接近开关的动作前提,必须是以润滑油泵电机工作正常和贮油筒中未断油脂为前提条件。

The lubrication system work detection adopts the proximity switch. The proximity switch is installed on the system oil separator. When the oil separator is working normally, the proximity switch will operate at the same time interval. When a certain oil circuit is blocked, the proximity switch will not operate. But it must be noted that the preconditions for the action of the oil separator or proximity switch must be the normal operation of the lubricating oil pump motor and the unbroken grease in the oil storage tank.

5.液压泵站滤油器压差报警

5. Hydraulic pump station oil filter pressure difference alarm

滤油器的压差报警,采用压差发讯装置。当滤油器使用一段时间后,过滤下的杂质可能将滤筒堵塞,造成滤油器两边油路压差增大,当增大至一定数值时,即由主控制柜发出声光报警信号。值得注意的是:只有当滤油器工作时才会发出信号。

The differential pressure alarm of the oil filter adopts the differential pressure signaling device. When the oil filter is used for a period of time, the filtered impurities may block the filter cartridge, causing the pressure difference between the two sides of the oil filter to increase. When it increases to a certain value, the main control cabinet sends out an audible and visual alarm signal. It is worth noting that the signal will only be sent when the oil filter is working.
