If you want to use the pump valve for a long time and correct maintenance and maintenance methods, how do the stainless steel pumps of the pump valve do?

(1) check the stainless steel pumps and pipes and the combination of the loosening of the phenomenon. The stainless steel pump is rotated with the hand to see if the stainless steel pump is flexible.

(2) add bearing lubricating oil to the bearing body, and observe that the oil level should be at the center line of the oil mark, and the lubricating oil should be replaced or supplemented in time.

(3) stainless steel drain plug unscrew the pump body, filling water (or lead paste).

(4) close the gate valve of the outlet pipe and the outlet pressure gauge and the imported vacuum meter. Health level self-priming pump

(5) point the motor to see if the motor's steering is correct.

(6) start the motor. When the stainless steel pump runs normally, turn on the outlet pressure gauge and the inlet vacuum pump. After it shows proper pressure, it will gradually open the gate valve and check the load of the motor.

(7) try to control the flow rate and the lift of stainless steel pump on the label, so as to ensure the operation of the stainless steel pump at the highest efficiency point, so that the maximum energy saving effect can be obtained. Inlet pump valve

(8) during the operation of the stainless steel pump, the bearing temperature should not exceed the ambient temperature 35C, and the maximum temperature should not exceed 80C.

(9) if a stainless steel pump is found to have abnormal sound, the reason should be stopped immediately.

(10) when the stainless steel pump is to be stopped, the gate valve, the pressure gauge, and the motor are stopped.

(11) the stainless steel pump in the first month of work, after 100 hours to replace the lubricating oil, after each 500 hours, oil change once.

(12) regularly adjust the packing gland to ensure that the drip leakage in the packing room is normal (suitable for dropping out).

(13) check the wear of the sleeve regularly and replace it in time when the wear is large.

(14) stainless steel water pump used in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net. To prevent cracking.

(15) long term use of stainless steel pumps, the need to remove all of the pump, dry water, the rotating parts and the combination of oil to be coated, properly kept.
