External factors affecting the mechanical seal of centrifugal pumps1. No auxiliary scouring system or unreasonable setting of auxiliary scouring systemThe auxiliary flushing system of mechanical seals is very important as it can effectively protect the sealing surface, play a role in cooling, smooth
The reason why the screw pump does not rotate1. The motor rotates and the screw pump body does not rotate-Check if the motor speed and speed ratio are normal to troubleshoot the motor.-Check whether the pump casing has too tight filling material, whether the medium inside the pump is smooth, and whe
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
The difference between different materials of water pump impellers1. Different corrosion resistance-Stainless steel impellers have a longer service life and are more hygienic.-Impeller made of bronze material with strong corrosion resistance and wear resistance-The impeller made of bronze material h
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
What is the reason for the cracking of the stainless steel water pump body1. The pump casing is cracked due to prolonged use, natural aging, and decreased pressure resistance.2. During transportation, the pump casing was strongly impacted with the inlet and outlet pipes, resulting in cracking of the
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
Reasons for damage to water pump bearings1. Improper installation of bearings1) The use of brute force during installation, such as directly striking the bearing with a hammer, can cause significant damage to the bearing and is the main cause of deformation2) Inadequate installation, installation de
