(1) Check the pump and piping and loose joints with or without the phenomenon. Turn the pump by hand to see if the pump is flexible. (2) Add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil standard, lubricating oil should be replaced or replenished promptly. (3) Unscrew the water diversion plug of the pump body and pour water (or slurry). (4) close the outlet valve and outlet pressure gauges and import vacuum gauge. (5) Move the motor to see if the motor is steered correctly. (6) start the motor, when the pump is running, open the outlet pressure gauge and inlet vacuum pump, depending on the appropriate pressure showed, gradually open the gate valve, while checking the motor load conditions. (7) try to control the flow of the pump and head within the range indicated on the sign to ensure that the pump at maximum efficiency point of operation, in order to get the maximum energy-saving effect. (8) During the operation of the pump, the bearing temperature can not exceed the ambient temperature 35C, the maximum temperature must not exceed 80C. (9) If the pump is found abnormal sound should stop immediately check the reasons. (10) To stop using the pump, first close the gate valve and pressure gauge and then stop the motor. (11) pump in the first month of work, after 100 hours to replace the oil, after every 500 hours, oil change time. (12) Regularly adjust the packing gland to ensure the normal drip leakage in the packing room (as a drop of leakage is appropriate) (13) Check the wear and tear of the bushing regularly, after wear and tear should be promptly replaced. (14) When the pump is used in the winter season, after the pump is stopped, unscrew the drain plug at the lower part of the pump to release the medium to prevent the cracking. (15) long-term deactivation of the pump, the pump should be disassembled all, dry the water, the rotating parts and joints coated with grease installed, properly preserved.
