⑺Check whether there is any debris that hinders its operation when the moving roller shaft system moves horizontally, and whether it may interfere with other equipment, especially whether there are foreign objects or iron blocks between the two grinding rollers and the four bearing seats that hinder the movement of the moving roller;

⑻主机架各联接部分安装就位,联接螺栓组均已按规定拧紧力矩均匀拧紧;

⑻The connecting parts of the main frame are installed in place, and the connecting bolt groups have been evenly tightened according to the specified tightening torque;

5.液压系统中各压力控制阀和压力表参数的设定关系(参照液压系统图).

5.The setting relationship of the pressure control valve and pressure gauge parameters in the hydraulic system (refer to the hydraulic system drawing).

设:⑴电接点压力表上限压力为PD上;

Set: ⑴The upper limit pressure of the electric contact pressure gauge is PD;

   ⑵电接点压力表下限压力为PD下;

⑵The lower limit pressure of the electric contact pressure gauge is PD;

   ⑶蓄能器充气压力为Px;

⑶The charging pressure of the accumulator is Px;

   ⑷电磁液流阀调定压力为Pv1;

⑷The set pressure of the electromagnetic liquid flow valve is Pv1;

⑸泵站溢流阀调定压力为Pv2;

⑸The setting pressure of the overflow valve of the pumping station is Pv2;

⑹压力传感器调定压力为PcY;

⑹The set pressure of the pressure sensor is PcY;

⑺低压腔溢流阀调定压力为Pv3;

⑺ The setting pressure of the relief valve in the low pressure chamber is Pv3;

则:⑴PD上-PD下=1.2～2.0Mpa;

Then: ⑴PD up-PD down=1.2～2.0Mpa;

   ⑵PD下-Px≥0.6～1.5Mpa;

⑵ PD under -Px≥0.6～1.5Mpa;

   ⑶Px≥0.6PD上;

⑶Px≥0.6PD;

   ⑷PcY-PD上=2.0～2.2Mpa;

⑷PcY-PD upper=2.0～2.2Mpa;

   ⑸Pv1-PD上=1.5～2.0Mpa;

⑸Pv1-PD upper=1.5～2.0Mpa;

   ⑹Pv2-PD上=1.5Mpa;

⑹Pv2-PD upper=1.5Mpa;

   ⑺Pv3=3.5～4.0Mpa;

⑺Pv3=3.5～4.0Mpa;

设定依据:电接点压力表上,下限压力差值越小,挤压出的物料物理性能一致性越好,但液压系统工作时有压力波动,因而一般差值大小按三倍于波动压力调定 。

Setting basis: On the electric contact pressure gauge, the smaller the lower limit pressure difference, the better the consistency of the physical properties of the extruded material. However, the hydraulic system has pressure fluctuations when it is working, so the difference is generally set at three times the fluctuation pressure.

蓄能器的充气压力与电接点压力表下限越接近,系统加压的时间就越短,但它们的差值不应小于波动压力的1.5～2倍,充气压力同时不应小于电接点压力表上限压力的60%,否则蓄能器内的皮囊易损坏 。

The closer the charging pressure of the accumulator is to the lower limit of the electric contact pressure gauge, the shorter the time for the system to pressurize. But their difference should not be less than 1.5 to 2 times of the fluctuating pressure, and the inflation pressure should not be less than 60% of the upper limit pressure of the electric contact pressure gauge, otherwise the bladder in the accumulator is easily damaged.

从以上各参数的设定关系还可看出PY1 、PY2 、PCY的大小关系为PCY＞PV1＞PV2,这亦反映出系统的三重保护措施:1.当系统压力超过泵站溢流阀设定压力PV2时,则通过该溢流阀卸压,对系统起保护作用;2.若泵站溢流阀失灵,则通过电磁溢流阀对系统卸压,同样起到保护作用;3.若以上两溢流阀都失灵,则通过压力传感器将系统压力传给控制系统,由控制系统实行联锁停机 。

From the setting relationship of the above parameters, it can be seen that the size relationship of PY1, PY2, and PCY is PCY>PV1>PV2, which also reflects the system's triple protection measures: 1. When the system pressure exceeds the set pressure PV2 of the overflow valve of the pumping station, the pressure is relieved through the overflow valve to protect the system; 2. If the overflow valve of the pumping station fails, the electromagnetic overflow valve is used to relieve the pressure of the system, which also plays a protective role; 3. If the above two overflow valves fail, the system pressure is transmitted to the control system through the pressure sensor, and the control system implements interlocking shutdown.

根据原理图可看出,系统的最高压力为16.0Mpa,工作压力依据具体情况而定,一般为7～9Mpa 。

It can be seen from the schematic diagram that the maximum pressure of the system is 16.0Mpa, and the working pressure depends on the specific conditions, generally 7-9Mpa.

7.液压系统试车

7. Hydraulic system commissioning

液压系统主要可划分为以下三个回路:加压回路,退辊回路,压力保护回路,在进行试车时,可按以下步骤进行:

The hydraulic system can be divided into the following three circuits: pressurization circuit, roll back circuit, pressure protection circuit, during the test run, the following steps can be carried out:

⑴调试泵站压力,检验齿轮泵和油泵电机的工作性能

⑴ Debug the pressure of the pump station, check the working performance of the gear pump and oil pump motor

①将泵站溢流阀(件6)手柄调于最松状态;

① Adjust the handle of the pump station relief valve (part 6) to the most loose state;

②三位四通换向阀(件7)处于失电状态;

②The three-position four-way reversing valve (part 7) is in the power-off state;

③启动油泵电机;

③Start the oil pump motor;

④确认电机及油泵运转正常平衡后,缓慢拧紧溢流阀手柄,以1Mpa为一递升速度,使油泵压力为逐步上升至10Mpa,在此期间注意其调节是否灵活 。

④ After confirming that the motor and the oil pump are running normally and balanced, slowly tighten the relief valve handle, and use 1Mpa as the step-up speed to gradually increase the oil pump pressure to 10Mpa. During this period, pay attention to whether its adjustment is flexible.

注:在调试过程中,若出现齿轮泵密封圈处往外冒油,则可考虑是否油泵电机反接 。

Note: During the debugging process, if oil is leaking from the gear pump seal ring, you can consider whether the oil pump motor is reversed.

⑵用进辊油路给系统排气

⑵Using the roller inlet oil circuit to exhaust the system

①根据设定的充气压力给蓄能器充气;

① Inflate the accumulator according to the set inflation pressure;

②将各元件调至使移动辊推进的状态;

② Adjust the components to the state where the moving roller is pushed forward;

③起动油泵电机,以设定的压力给系统充油排气 。注意观察两侧排气阀处(或压力表开关安装处)是否有油冒出 。若两侧都没冒油或只有一侧冒油,都应继续往系统中充油,直到出油为止 。待系统中气体都排出后,方可拧紧排气阀(或装好压力表) 。

③Start the oil pump motor and fill the system with oil and exhaust at the set pressure. Pay attention to whether there is oil coming out of the exhaust valve on both sides (or at the pressure gauge switch installation place). If there is no oil on both sides or only one side, you should continue to fill the system with oil until the oil comes out. Tighten the exhaust valve (or install the pressure gauge) after the gas in the system is exhausted.

注:在只有一侧冒油的情况下,可将该侧的排气阀拧紧关闭,再往系统中充油 。

Note: When only one side is emitting oil, the exhaust valve on that side can be tightened and closed, and then the system can be filled with oil.

⑶调试各油路,检验系统各元器件的可靠性和灵敏度 。

⑶ Debug each oil circuit, check the reliability and sensitivity of each component of the system.

三.润滑系统试车

3. Lubrication system commissioning

将润滑系统安装好 ，注意各个润滑点的管接头处暂时脱开不装 。

Install the lubrication system, and pay attention to the temporary disconnection of the pipe joints of each lubrication point.

该润滑系统共有14个润滑点,这14个润滑点的分布是:四个轴承座,每个轴承座上三个润滑点共有十二个润滑点,两个下导轨,每个导轨上一个润滑点共有两个个润滑点,各润滑点所需油量的多少是根据设备的运转特点 ，按时间 、次数来由系统分点供油 。

The lubrication system has a total of 14 lubrication points. The distribution of these 14 lubrication points is: four bearing seats, three lubrication points on each bearing seat, a total of twelve lubrication points, two lower guide rails, one on each guide. There are two lubrication points in total, and the amount of oil required for each lubrication point is based on the operating characteristics of the equipment, and the system will supply oil at points according to time and frequency.

具体操作如下 ：

The specific operations are as follows:

   ⑴检查确认压力传感器及显示仪表的接线是否正确 ；

   ⑴Check whether the wiring of the pressure sensor and display instrument is correct;

   ⑵将液压系统调节至不同的压力 。调整显示仪表上的指示数值 。在2～12.0Mpa的范围内其压力显示误差不大于±0.3Mpa在7～11Mpa的范围内其误差不大于±0.1Mpa 。

   ⑵Adjust the hydraulic system to different pressures. Adjust the indicated value on the display instrument. In the range of 2～12.0Mpa, the pressure display error is not more than ±0.3Mpa, and the error in the range of 7～11Mpa is not more than ±0.1Mpa.

   4 、润滑系统正常工作检测

   4. Detection of normal operation of lubrication system

   ⑴检查确认接近开关和指示灯的接线是否正确 ；

   ⑴Check whether the wiring of proximity switch and indicator light is correct;

   ⑵将接近开关装于递进式分配器的接近开关安装座上 。调整好接近开关头部与分油器滑杆间的距离 ，使其在规定的范围内 ；

   (2) Install the proximity switch on the proximity switch mounting seat of the progressive distributor. Adjust the distance between the head of the proximity switch and the sliding rod of the oil separator to make it within the specified range;

   ⑶启动油泵电机 ，观察当分油器滑杆移动时 ，接近开关的指示灯是否随之有规律地闪动 。

   (3) Start the oil pump motor and observe whether the indicator light of the proximity switch flashes regularly when the oil separator slide rod moves.
