How can the flow rate of submersible pumps decrease?Reasons for flow decrease:1. The impeller or pump body fluid flow path is blocked by debrisTreatment method: Disassemble the submersible pump, remove debris from the impeller or pump body flow path, make the impeller rotate smoothly and quickly, an

What is the impact of different impellers on the water pump1. Runner type impellerThe runner impeller is a curved runner that flows from the inlet to the outlet. Because this impeller has excellent anti clogging performance.-Suitable for conveying liquids containing large particle impurities or long

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

How to disassemble the submersible pump1. Use a wrench to remove the water pump power inlet box, and pay attention not to damage the sealing rubber ring. Remove the power cord, use pliers to cut the three wires of the input motor coil, that is, two power lines, and one line in series with the capaci

How to deal with oil leakage of submersible pumpThere are two possibilities for oil leakage of submersible pump: -The seal box is severely worn, resulting in oil leakage in the oil chamber of the seal box.-The cable has oil, or the cable used after maintenance does not meet the specifications, resul
