Abstract

The invention provides a booster pump for seawater desalination. The booster pump for seawater desalination comprises a pump body, an impeller, a pump cover, a bearing body, a bearing assembly, a front bearing gland and a rear bearing gland; the impeller is positioned in a cavity of the pump body, mounted at the left end of a shaft, and provided with a balance hole; the pump cover is positioned onthe right side of the impeller; the bearing body is arranged on the right side of the pump cover; the bearing assembly is fixedly mounted on the bearing body and comprises a cylindrical roller bearing and an angular contact ball bearing; the front bearing gland is positioned on the left side of the cylindrical roller bearing, and is connected with the bearing body; and the rear bearing gland is positioned on the right side of the angular contact ball bearing, and is connected with the bearing body. The booster pump can effectively reduce the influence of high inlet pressure, excessive axial force and seawater corrosion on the integral normal operation of the booster pump.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a booster pump for seawater desalination. Background technique [0002] Seawater resources in the world account for about 97% of the total water resources, so desalination of seawater is an effective means to solve the shortage of freshwater resources. The booster pump used in seawater desalination is mainly used in the reverse osmosis seawater desalination circuit to compensate for the pressure loss in energy recovery. On the one hand, considering that the working pressure at the pump inlet will generate a large axial force, poor balance will lead to increased bearing wear and excessive temperature. On the other hand, the medium is seawater, which makes the working environment complicated, and the seawater has high salinity, so the corrosion resistance of the booster pump needs to be considered. [0003] Therefore, the general single-stage single-suction centrifugal pump c...
