Stainless steel magnetic pump consists of pump, magnetic drive and motor. The key component of the magnetic drive is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. Stainless steel magnetic pump has many advantages, which are embodied in safety, no leakage, corrosion resistance and acid resistance. What are the common faults of stainless steel magnetic pump:
1. Problems caused by cavitation of the magnetic pump: The main reasons for the cavitation of the pump are the large resistance of the pump inlet pipe, the large gas phase of the conveying medium, the insufficient filling of the pump, and the insufficient energy head of the pump inlet. Cavitation is very harmful to the pump. When cavitation occurs, the pump vibrates violently and the balance is seriously damaged, which will cause damage to the pump bearing, rotor or impeller. This is a common cause of magnetic pump failures.
2. No medium or small flow rate of conveying medium: make the rotor main shaft dry with the stable bearing, and burn the bearing. The magnetic pump is lubricated and cooled by the conveying medium to the sliding bearing. Without opening the inlet valve or the outlet valve, the sliding bearing will be damaged due to high temperature due to the lack of lubrication and cooling of the conveying medium.
3. Damage to the isolation sleeve: The magnetic coupling of the chemical magnetic pump is cooled by the medium conveyed by the pump. If there are hard particles in the medium, it is easy to cause the isolation sleeve to be scratched or pierced, and sometimes it may also be caused by improper maintenance methods. Damage to the isolation sleeve.
