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.
八．辊罩
8. roller cover
辊罩的主要作用:其一是防止发生意外的人员伤亡和设备损坏亊故;其二是起到密封、减少扬尘的作用。在两辊罩上均开有观察检修门孔,可以在设备运转时随时检查辊面磨损情况。
The main function of the roller cover: One is to prevent accidental casualties and equipment damage; the other is to seal and reduce dust. Both roller covers are provided with observation and inspection door holes, so that the wear of the roller surface can be checked at any time when the equipment is running.
