Bearing assembly device of sea water desalination booster pump

Abstract

The invention discloses a bearing assembly device of a sea water desalination booster pump, and belongs to the field of bearing application. The bearing assembly device comprises a front framework oilseal, a front bearing gland, a cylindrical roller bearing, an oil pointer, a bearing body, a ventilator, a one-way thrust bearing, a bearing pressing nut, a rear bearing gland, a rear framework oil seal, a fan and a fan cover. According to the bearing assembly device, a combined structure of two rows of leftward angular contact ball bearings and a row of rightward angular contact ball bearings isapplied, the excessive axial force generated by high-pressure liquid of the sea water desalination booster pump is averagely decomposed, and the problems that due to poor axial force balance, bearingabrasion and high-temperature damage are caused are effectively solved. The fan is assembled at the tail end of a shaft, and the bearings are cooled and protected. The bearing assembly device is particularly applied to the situations of excessive abrasion and high-temperature damage due to excessive axial force.

Description

technical field [0001] The invention belongs to the technical field of bearing applications, and in particular relates to a seawater desalination booster pump designed to reduce excessive wear and high temperature caused by excessive axial force when the seawater desalination booster pump transports high-pressure liquid. Bearing assembly unit for pumps with 4 disc bearings. Background technique [0002] When the seawater desalination booster pump delivers liquid, the pressure at the mouth is high, and the pressure of the high-pressure liquid at the suction port cannot be balanced, resulting in a large axial force on the rotor. If the axial force is too large, if the balance is not good, the rotor will move to the driving end. Movement, causing axial positioning bearing wear or damage due to excessive temperature. [0003] How to balance the axial force and prevent the temperature of the bearing from being too high through reasonable structural design, so as to improve the s...
