Helping the economic growth of China and the world with high-quality products has become an important force in the pump industry.

How to improve the NPSH of the slurry pump?

There are both external and internal causes for cavitation in the slurry pump, and the external cause acts through the internal cause. The external factor is the NPSH of the device, which is the energy provided by the device that exceeds the vaporization pressure at the inlet of the slurry pump, and the internal factor is the NPSH of the slurry pump, which is provided by the slurry pump itself at the pump inlet. Energy beyond vaporization pressure. The NPSH of the pump indicates the quality of the anti-cavitation performance of the pump itself.

How to calculate the service life of the wearing parts of the slurry pump

The life of the wearing parts of the slurry pump is related to many factors, the particle size and gradation of the solid particles, the suction conditions, and the parameters of the pump. When the slurry contains large solids, the impeller life is very short due to the wear at the blade inlet, which is significantly shorter than the life of the seal. When conveying fine particle slurries, the life of seals and impeller inlet side and front fenders is approximately equal to or less than the impeller life.

How to replace the packing seal in the slurry pump?

How to replace the packing in the slurry pump? The first thing we need to determine when replacing the packing is that the packing sealing structure is divided into two types, one is the packing sealing structure, and the other is the impeller sealing structure. The two seal replacement packings are different!
