What to do if the submersible pump is out of phase and always burns the motor?

The submersible pump is three-phase and always burns out the motor, indicating that phase loss is a common occurrence. Therefore, the maintenance approach should be carried out from top to bottom. If the cause of the phase loss cannot be found, then all technical measures are to address the symptoms rather than the root cause. The search approach is from top to bottom. When the motor is in phase loss, use a multimeter to determine which phase of ABC three-phase has a problem, follow the circuit

Construction, selection, maintenance, and assembly and disassembly techniques for pipeline pumps

The basic structure of a pipeline pump is composed of six parts: impeller, pipeline pump body, pump shaft, bearing, sealing ring, and packing box. According to different installation methods, it can be divided into vertical pipeline pumps and horizontal pipeline pumps. The common letters are ISG and ISW1. The impeller is the core part of a centrifugal pump, with high rotational speed and high output. The blades on the impeller play a major role, and the impeller needs to undergo static balance e

Summary of lubrication and maintenance mechanisms commonly used for motors and water pumps

Lubrication is the addition of lubricant between two friction surfaces in relative motion, forming a lubricating film between the two friction surfaces, separating the dry friction surfaces that were originally in direct contact, and transforming dry friction into friction between lubricant molecules, in order to reduce friction, reduce wear, and extend the service life of mechanical equipment.
