(2) Add bearing lubrication oil to the bearing body. Observe that the oil level should be at the centerline of the oil standard. Lubricating oil should be replaced or supplemented in time.
(3) Unscrew the water diversion plug of the pump body of the vacuum pump and infuse diversion (or lead).
(4) Close the gate valve, outlet pressure gauge and import vacuum gauge of the outlet pipe.
(5) Jog the motor to see if the motor steering is correct.
(6) Turn on the motor. When the vacuum pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. After seeing the proper pressure, gradually open the gate valve and check the motor load condition.
(7) Try to control the flow rate and lift of the vacuum pump within the range specified on the label to ensure that the vacuum pump is operating at the highest efficiency point in order to obtain maximum energy savings.
(8) During the operation of the vacuum pump, the bearing temperature must not exceed the ambient temperature 35C, and the maximum temperature must not exceed 80C.
(9) If abnormal noise is found in the vacuum pump, stop immediately to check the cause.
(10) When the vacuum pump is to be stopped, close the gate valve and pressure gauge first, and then stop the motor.
(11) In the first month of working, the vacuum pump will replace the oil after 100 hours, and after each 500 hours, change the oil once.
(12) Adjust the packing glands regularly to ensure that the drip chambers are in normal condition (in case of drip leakage).
(13) Regularly inspect the bushings for wear, and replace them if worn.
(14) When the vacuum pump is used during the winter season, after the vehicle is stopped, the lower water release screw plug of the pump body must be unscrewed to release the medium. Prevent freezing cracks.
(15) When the vacuum pump is decommissioned for a long period of time, it is necessary to disassemble the pump completely, wipe off the water, and apply the grease to the rotating parts and joints to properly store it.
