Because there is a certain system in the cavity of the stainless steel magnetic pump and the "static bearing" is used in the magnetic pump, the stainless steel magnetic pump must not be used in the system with pressure, and both positive pressure and negative pressure are not feasible. . 1. Because the cooling and lubrication of the stainless steel magnetic pump bearing depends on the conveye...

A few days ago, our company technician went to an environmentally friendly customer to repair a filter, mainly because the 3HP magnetic pump in the filter was broken and could not work. Our technicians went to the scene and found that the pump head was damaged due to the idling of the magnetic pump and the pump head had to be changed. In fact, it is the second time that we have repaired ...

1. The key to the installation technology of fluoroplastic centrifugal pump is to determine the installation height (suction distance) of fluoroplastic centrifugal pump, which refers to the vertical distance between the water source surface and the center line of chemical centrifugal pump impeller, which should not be confused with the allowable vacuum suction height. The allowable vacuu...

Before starting the centrifugal pump, it should first be filled with water to discharge the air from the pump shell. From the working principle of the centrifugal pump, when the impeller rotates, the water is thrown to the outer edge of the impeller by the centrifugal force, the vacuum is formed at the center of the impeller, and the water is sucked into, forming the continuous working proces...

1. Magnetic pump cavitation: the main causes of pump cavitation are large resistance of pump inlet pipe, more gas phase of conveying medium, insufficient filling pump, insufficient energy head of pump inlet and so on. Cavitation does great harm to the pump. When cavitation occurs, the pump vibrates violently and the balance is seriously damaged, which will lead to damage to the bearing, rotor or i...
