Maintenance method of agricultural submersible pump in slack season1. Check vulnerable parts: the impeller, retaining ring, shaft sleeve, bearing seat, etc. of the submersible pump are vulnerable parts. First, remove the water pump and check whether the vulnerable parts are intact. It is forbidden t

Remedial method for water leakage of submersible pumpMost of the water leakage failures of submersible pumps are caused by aging and wear of sealing devices. In addition to replacing new sealing elements, the following simple methods can also be taken to remedy.1、 The sealing ring of the submersible

Preparation before use of submersible pump1. Check whether the cable is broken or broken. Before use, not only observe the appearance of the cable, but also use a multimeter or megohmmeter to check whether the cable is connected. There shall be no oil leakage at the cable outlet.2. Before the use of

Why do some submersible pumps need water before use? Submersible pumps, as the name implies, are put in water to work. But when purchasing submersible pumps, some manufacturers will remind them to add water before starting. If there is air inside the pump, air binding will occur after starting, that is, light can not absorb water.

Common sense of submersible pumpSubmersible pump is widely used in various industrial, agricultural and domestic water transmission. Before using the submersible pump, we need to understand its relevant common sense to avoid unnecessary losses.

The reason why the water pump motor cannot start and has buzzing noise:(1) One phase of the power line is broken.(2) The fusible link fuses one phase.(3) One phase of the winding of the "Y" type connection motor is broken“ Δ” There is one or two phase disconnection in the type connection motor.(4) F

Reasons for motor heating1. The quality of the motor itself is poor, and the heat dissipation is poor. If this happens, contact the manufacturer and replace it in time.2. Due to the incorrect selection of water pump, the high lift pump operates under low pressure, which will cause excessive flow at

Difference between deep well pump and submersible pump The common point of submersible pump and deep well pump is the pump under potential water. difference-Submersible pump is a single-stage impeller with small head, large pump body and small power. Submersible deep well pump long-shaft deep well pump
