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...

The self-priming centrifugal pump is a kind of pump which uses the electric impeller of the motor to rotate at a high speed, thus using the centrifugal force to lift, transport and circulate the liquid. With acid and alkali anti-corrosion pump body, as well as long-term and stable product characteristics. It is widely used in electroplating industry. So what problems should be paid attention to in...

Many customers in the use of fluoroplastic lined centrifugal self-priming pump work, found that the self-priming pump can not absorb water, do not know what is the cause, and will not repair. With the principle of fluoroplastic lined centrifugal self-priming pump, talk about what to do in this situation. 1. Air leakage. The interior of the self-priming pump is closed, and when the self-primin...

The speed ratio of a centrifugal pump refers to the frequency at which the pump shaft rotates in a unit time. Public n stands for Enterprise:r/min. The usual centrifugal pump has the increase of 2900r/min or 1450r/min, while the large centrifugal pump has 970r/min or 730r/min. When the speed ratio is fixed, the total flow rate, pump head and output power are all fixed. The speed ratio of centrifug...
