Four major faults of submersible pumps and corresponding measuresThe submersible pump motor cannot start and is accompanied by a buzzing sound:1. Check the motor circuit for one phase open circuit, check the voltage, and check if the voltage is too low.Solution: Repair the circuit and adjust the vol

Remedial methods for water leakage of submersible pumps1.The sealing ring of the submersible pump loses elasticity due to long-term use-Take out the sealing ring, cut a piece of paper or cloth with a thickness of 0.3 to 0.5 millimeters into a pad slightly larger than the original sealing ring, insta

How to maintain water pumps during the rainy season1、 Centrifugal pump-Lift the pump and hose out of the well and discharge the water inside the pump and hose.-According to technical requirements, carefully inspect the impeller, bearings, cups and other parts of the water pump. If there is any damag

How to determine whether a submersible motor is copper core or aluminum core1. Copper has better conductivity than aluminum. The current carrying capacity of copper wire cables is 6A per square meter, while aluminum wire cables are 5A. Therefore, aluminum wire cable motors are very prone to overheat

Advantages and disadvantages of high lift deep well pumpsDisadvantages:1. There are limitations in the structure of submersible pumps, such as a smaller head range than chemical pumps, which greatly affects the selection range.2. Submersible pumps are partially immersed in the medium during operatio

What happens when the stainless steel water pump impeller is installed upside downThe impact of impeller inversion:1. If the stainless steel water pump impeller is installed upside down, it will affect the water flow rate, which is relatively small, and even cause the phenomenon of not being able to

Reasons for severe shaking of stainless steel water pumps1. Loose flange and boltsThe bolt is subjected to lateral load and torque, which can easily cause the bolt to rotate and loosen. When the bolt is loose, failure to tighten it in a timely manner can lead to strong shaking of the water pump.2. M

How to prevent corrosion of submersible pumps?Controlling the corrosion of underground water on submersible pumps mainly involves two aspects:First, improve the corrosion resistance of pipes and use materials with good corrosion resistance.Second, remove or suppress some factors that cause corrosion

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

Characteristics of high-temperature resistant submersible pump1. The high-temperature resistant submersible pump has an ultra-long service life, no maintenance required, small size, high efficiency, and low power consumption.2.The stator and circuit board of the motor are sealed with epoxy resin and
