Why does a submersible pump not release water when drainingReason:1. Poor connection of water pipe interface: The water pipe connected to the outlet of the submersible pump is not connected properly, or the water pipe is damaged, which can cause the submersible pump to not discharge water when place

Reasons and solutions for oil leakage in submersible pumps1、 Reasons for oil leakageMechanical seal damageMechanical seals are key components in preventing oil leakage. If the seals age, wear, or are installed improperly, it can lead to oil leakage.Reason: Long term operation, impurities in water qu

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

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

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

Factors to consider when choosing a suitable submersible pump 1‌. Application scenarios: There are various types of submersible pumps, such as well submersible pumps, submersible sewage pumps, and working face submersible pumps, each suitable for different scenarios.
