Vertical pump bearing lubrication cooling device

Abstract

The invention relates to the technical field of lubrication of vertical pump bearings, in particular to a vertical pump bearing lubrication cooling device. The vertical pump bearing lubrication cooling device comprises a shaft, a bearing frame, an outer sleeve, a bearing gland, an upper bearing, a shaft sleeve, a lower bearing and a spiral sleeve. The spiral sleeve is connected to the shaft. The upper bearing, the shaft sleeve and the lower bearing are connected to the spiral sleeve. The spiral sleeve is provided with an oil rotating section. The oil rotating section is provided with trapezoidal threads I and trapezoidal threads II. An oil collecting groove is formed between the trapezoidal threads I and the trapezoidal threads II. The thread rotating direction of the trapezoidal threads Iis opposite to that of the trapezoidal threads II. An oil outlet pipe connecting pipe is provided with an oil outlet hole. A gland connecting pipe is provided with an oil inlet hole. An oil outlet pipe is connected between the oil outlet hole and the oil inlet hole. The vertical pump bearing lubrication cooling device solves the problem that a bearing on a vertical pump is hard to lubricate, meanwhile, the requirement for bearing lubrication at the low rotating speed can be met, the air cooling and heat dissipation functions are achieved, the temperature of the outer sleeve and the temperature of the bearings are effectively reduced, a good environment is provided for bearing running, and safe running of the vertical pump is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vertical pump bearing lubrication, in particular to a vertical pump bearing lubrication and cooling device. Background technique [0002] Vertical pumps such as submerged pumps and long wheelbases are widely used, but due to the structural characteristics of vertical pumps, the cooling and lubrication of the bearing body has always been a problem that needs to be solved. [0003] The existing technology patent number is "CN201020165890.9", and the invention patent application titled "New Air-cooled Structure High Temperature Molten Salt Pump" discloses a new type of air-cooled structure high-temperature molten salt pump, which mainly uses the principle of air-cooled heat dissipation for the bearing To dissipate heat, but this prior art mainly cools the shell of the bearing body, and the lubrication of the bearing also needs to rely on an external oil replenisher. [0004] The prior art patent number is "...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a vertical pump bearing lubricating and cooling device, which solves the problem that the upper bearing in the vertical pump oil lubricated bearing is difficult to lubricate and the problem of cooling the vertical pump bearing, so that the bearing can run in a good environment and ensure the vertical safe operation of the pump
