1、隔膜泵啟動前的準備工作：
（1）檢查隔膜泵進出口過濾網(wǎng)是否暢通。
（2）檢查隔膜泵出口管線、回流管線是否暢通，投用相關儀表、調節(jié)閥。
2、隔膜泵的啟動
（1）打開隔膜泵入口閥，確認入口管線是否暢通。
（2）開啟隔膜泵出口閥。
（3）將泵沖程調節(jié)器調節(jié)為零。
（4）啟動隔膜泵，確認電機旋轉方向是否按電機上箭頭所示方向旋轉，確認隔膜泵泵無異音。
（5）隔膜泵啟動后確認工作：
①確認隔膜泵體各部件是否存在異音。
②確認隔膜振動是否正常。
⑤確認隔膜泵泵柱柱塞填料處是否泄漏或過熱。
⑥觀察隔膜泵出口壓力與流量是否正常，并確認電機電流是否符合要求，并做好記錄。
氣動隔膜泵
3、隔膜泵正常運轉時巡檢的要點：
（1） 檢查隔膜泵出口壓力，出口流量是否滿足要求。
（2）檢查隔膜泵泵體上各軸承溫度是否高于正常溫度。
（3）檢查振動是否正常。
（4）檢查填料是否泄漏或過熱。
（5）檢查進出口單向閥是否正常。
（6）確認各管線是否存在泄漏點。
4、停泵：
（1）確認沖程調節(jié)器指針調到零位，停泵。
（2）停泵后將隔膜泵與系統(tǒng)隔離，如需檢修，則必須將泵體內介質清洗排凈。
1, diaphragm pump before starting the preparatory work:
(1) Check whether the inlet and outlet filter of the diaphragm pump is smooth.
(2) check the diaphragm pump outlet pipeline, return pipeline is smooth, use relevant instruments, regulating valve.
2. Start of diaphragm pump
(1) Open the inlet valve of the diaphragm pump to confirm whether the inlet pipeline is smooth.
(2) open the diaphragm pump outlet valve.
(3) Adjust the pump stroke regulator to zero.
(4) Start the diaphragm pump and confirm whether the motor rotates in the direction indicated by the arrow on the motor, and confirm that the diaphragm pump has no sound.
(5) Confirm work after starting diaphragm pump:
(1) Confirm whether the parts of the diaphragm pump body are abnormal.
② Confirm whether diaphragm vibration is normal.
Confirm whether the diaphragm pump plunger packing leakage or overheating.
⑥ Observe the diaphragm pump outlet pressure and flow is normal, and confirm whether the motor current meets the requirements, and make a record.
Pneumatic diaphragm pump
3, diaphragm pump normal operation of the main points of inspection:
(1) Check the outlet pressure of the diaphragm pump and whether the outlet flow meets the requirements.
(2) Check whether the bearing temperature on the diaphragm pump body is higher than the normal temperature.
(3) Check whether the vibration is normal.
(4) Check whether the packing is leaking or overheating.
(5) Check whether the import and export check valve is normal.
(6) Confirm whether there is leakage point in each pipeline.
4. Stop the pump:
(1) Confirm that the stroke regulator pointer is set to zero and stop the pump.
(2) after stopping the pump, the diaphragm pump is isolated from the system. If maintenance is required, the medium in the pump must be cleaned and drained.
