RSNThe centrifugal pump for ships is a two-stage pump, but unlike typical two pole pumps, in addition to the second stage having an outlet, the first stage also has a branch outlet. As a general general-purpose pump, this structure is most suitable for use as a ship pump and is typically used in the following situations:

1.RSNThe centrifugal pump for ships is a two-stage pump with a vertical structure. The inlet of the pump, the first stage branch outlet, and the second stage outlet are all horizontal.

2.The pump body, pump cover, and guide vanes form a fixed part of the flow passage. After the liquid exits the first stage impeller, it enters the annular pressure chamber, and then passes through the guide vanes into the second stage impeller and the second stage volute shaped pressure chamber.

3.Both the pump body and impeller have sealing rings, which can be replaced after wear. The new impeller has been made with the impeller sealing ring—After wear and tear, drive the part where the sealing ring is installed to the specified size, and then insert the sealing ring.

Adopting a single end non-equilibrium mechanical seal

The pump shaft bearing adopts grease lubricated rolling bearings. Upper bearing(Support bearing)Using two centripetal thrust ball bearings; lower bearing(guide bearing)Adopting radial ball bearings.
