On the high-lift and submersible pump vanes, the choice of the thrust bearing material should be careful, it is recommended to use graphite soaked alloy material. But do not use graphite Baptist Babbit, this material is easy to put them on the thrust plate mill ground cracks, and this especially in the high-lift submersible pump easily reflected. The best selection of thrust bearing material is meet the following requirements: high mechanical strength, wear resistance, self-lubricating properties, good thermal conductivity, corrosion resistance and strengthen cooling effect, rationalizing the structure, to ensure the strength of the thrust bearing case next, it can increase the diameter of the water holes. For friction should select the appropriate surface roughness.

Through the above analysis shows the axial force and thrust bearing performance only have great impact on the Shandong vacuum pump operation. In order to reduce the axial force, we intend to guide vane submersible pump submersible pump to diversion shell, reducing the height of diversion shell, improving single-stage lift, we have achieved some results. In order to improve the level of our motors, submersible motors should be in terms of the thrust bearing material under a great effort, greatly improve the thrust bearing capacity, further improve the market competitiveness.
