泵(隔膜式计量泵)的运转和维护： （一）开车： 1、开车前用手压紧补偿阀杆，此时，一面往膜腔内充油，一面排出膜腔内的气体，直到气泡不再往上冒为止。 2、开车后，在泵的柱塞作吸入运动中(排出管内无压力)用上述 方法将补偿阀杆压开，动作数次使安全阀跳开，让安全阀处的空气排出，直到气泡排出为止。 3、此时若有冲击声或振动现象，说明油量过多，应在柱塞作排出冲程时，用手轻压补偿阀杆，作短时的排油，使多余的排出，直至振动或冲击声xx后，泵运转平稳为止。 （二）停车： 切断电源，停止机泵运行。 关闭进出口管道阀门，弹开车前应注意打开。 （三）维护： 1、润滑油更换：一月更换一次润滑油， 加入合格的适量的23#或30#机械油。 泵在运行中，主要部位温度规定：电动机允许{zg}温度为70℃；调节机座内润滑油温度不得超过65℃；填料和温度不超过70℃。 2、漏损量：泵在正常运行中，其泄漏量每分钟不得超过15滴，对2)、3)条中如出现超标者，应联系有关单位进行处理，xx隐患。

Pump (diaphragm type metering pump) operation and maintenance of: (A) By car: One drive, hands pressed compensation valve stem, this time the one hand, oil-filled cavity to the membrane, membrane cavity of the gas discharge side until bubbles are no longer up to take up. 2, after driving in the pump plunger for inhalation movement (no pressure inside the discharge tube) using the method of compensation stem pressure to open the action several times to jump to open the safety valve so that the air discharge valve Department, until the air bubble discharge date. 3, at this time if the impact of noise or vibration, and shows too much oil should be discharged in the plunger stroke, the valve stem by hand soft reduction of compensation for short-term discharges of oil, so that the excess discharge, until the vibration or shock sound removed, the pump running smoothly so far. (B) Parking: Cut off the power to stop pump operation. Close the import and export pipeline valves, spring drive to open the former should be noted. (C) Maintenance: 1, lubricating oil replacement: an oil change in January, adding an appropriate amount of 23 qualified # or 30 # machine oil. Pumps in operation, the main part of the temperature requirements: motor allows a maximum temperature of 70 ℃; regulate oil temperature inside the base should not exceed 65 ℃; packing and temperature does not exceed 70 ℃. 2, the leakage: the pump in normal operation, the leakage shall not exceed 15 drops per minute, and 2), 3), such as those above the standard, should contact the relevant units for processing, to eliminate hidden dangers.
