The reason for the sudden decrease in water output of the submersible pump1. Impeller or pump body flow channel blockageReason: Impurities (such as water grass, sediment) block the impeller or pump body flow channel, resulting in a decrease in flow rate and head. ‌Solution: Disassemble the pump and

Classification and characteristics of submersible motors:Dry submersible motor: The interior of the dry submersible motor is filled with air, and the shaft extension end is equipped with mechanical sealing devices and rubber oil seals, which can prevent moisture and dampness from entering the interi

Methods to prevent damage to water pumps caused by prolonged disuseDisassemble and storeIf disassembly is convenient, the water pump and pipeline can be removed and cleaned thoroughly.Check the bearingsCheck the ball bearings, and replace them if the inner and outer sleeves are worn, loose, the ball

Reasons for the pump body to heat up when using the water pump:‌1. Bearing damage: Bearing damage will increase friction, causing the pump body to heat up. Insufficient or excessive lubricating oil (grease) in the bearing, poor quality, mud, iron filings and other debris, and bearing clearance that

The reasons for the recent rise in copper prices can be analyzed from the following aspects:1. Global economic recovery drives increased demandWith the gradual recovery of the global economy, especially the recovery and growth expectations of the Chinese economy, the demand for copper has significan

Reasons for excessive power consumption of submersible pumps 1. Overheating of bearings: The power machine and water pump shaft are subjected to excessive radial force, resulting in an increase in load and bearing heating.2. Too tight packing: Too tight packing makes the water diversion ditch not sm

How to choose the right water pump for different industriesChoosing the right water pump requires considering multiple factors, including application scenarios, medium characteristics, flow, head, power, etc.1. Agricultural irrigationDemand characteristics: large flow and medium head are required, a

What factors should be considered when selecting the flow rate, head, and power of a submersible pumpHead selection: Head refers to the height at which a submersible pump can lift water. Typically, the head should be 1.02 to 1.05 times the actual required head to ensure that the pump operates at a h

The main reasons why the submersible pump sometimes rotates and sometimes does not rotate include the following:1. Power supply problem: The submersible pump may have difficulty starting due to unstable power supply voltage or power failure. Low or high power supply voltage, damaged cables, poor con

What phenomena indicate that the water pump bearing is damaged:‌1. Abnormal noise: When the water pump bearing is damaged, different abnormal noises are usually emitted. Common noises include:‌Crunching sound: This sound is usually caused by friction between the steel ball in the bearing and the inn
