(1) Check the self-priming sewage pump pipeline and joints for looseness. If it is loose, the self-priming sewage pump will work normally, but the work efficiency will be reduced.
(2) Try to control the flow rate and lift of the self-priming sewage pump within the range indicated on the sign to ensure that the self-priming sewage pump operates at the highest efficiency point. Although theoretically, the data marked by the sign can be achieved by the pump. Prolonged to the edge of maximum efficiency, will increase the speed of pump aging.
(3) During the operation of the self-priming sewage pump, the bearing temperature should not exceed the ambient temperature of 35 °C, and the maximum temperature should not exceed 80 °C. The demand unit should communicate with the manufacturer when ordering the self-priming sewage pump. If the requirements are not met, the bearing material should be replaced or other pumps should be used.
(4) If the self-priming sewage pump is found to have abnormal sound, stop immediately and check the cause.
(5) When the sewage pump is to be stopped, first close the gate valve and pressure gauge, then stop the motor.
(6) When the self-priming sewage pump is not used for a long time and used in the cold winter season, after stopping, the water plug of the lower part of the pump body should be unscrewed to release the medium. Prevent freezing cracks. If it is sewage, please clean the pump chamber with clean water. Avoid sewage and mud slabs.
(7) Carefully listen to whether the running sound of the motor is abnormal. Because the machine room is noisy during operation, you can use the auxiliary tools such as a screwdriver or a stick to close the two ends of the motor to hear the bad vibration of the motor and its dragging device. Therefore, timely add bearing oil, or replace the new bearing and other corresponding measures to avoid the motor bearing dry oil and dry grinding and block, turn the outer circle, broom burnout.
Advantages of ZW self-priming sewage pump products:
1. Strong sewage discharge capacity: special impeller anti-blocking design ensures that the pump is efficient and non-blocking.
2, high efficiency and energy saving: the use of excellent hydraulic model, the efficiency is 3 to 5% higher than the general self-priming pump.
3, self-priming performance: self-priming height is 1 meter higher than the general self-priming pump, and the self-priming time is shorter.
