Slurry pump bracket end bearing oil seat structural combination

Abstract

Disclosed is a slurry pump bracket end bearing oil seat structural combination. The slurry pump bracket end bearing oil seat structural combination comprises a bracket body 1, a bearing 3, a bear end cover 4, an oil seal 5', a shaft sleeve 6 which sleeves a pump spindle and rotates along with the pump spindle, a cooling water channel 8, a vertical oil drainage channel 9 and a machine a sump 10. The slurry pump bracket end bearing oil seat structural combination is characterized in that the oil seal 5' is mounted inside the flange of the bearing end cover 4 and fixed firmly; the flange of the bearing end cover 4 and the bracket body 1 are compressed through a sealing gasket and can avoid oil leakage; the cooling water channel 8 is arranged around the bearing 3 and used for reducing the working temperature of lubricant and the oil seal 5'; the vertical oil drainage channel 9 comprises a first channel perpendicular to the pump spindle, and a second channel parallel to the pump spindle, wherein the first channel and the second channel are communicated with each other and rapidly drain returned machine oil passing through the bearing to the bottom of the sump 10; the oil seal 5' is of a fluororubber double-lip structure with a metal framework.

Description

technical field [0001] The invention relates to the field of centrifugal slurry pumps, in particular to a structural combination of bearing oil seals at both ends of a bracket of the centrifugal slurry pump. Background technique [0002] Slurry pump is a kind of equipment used to transport fluid medium containing solid particles, that is, slurry. It is used in many industries such as metallurgy, coal, electric power, chemical industry, building materials, mine production, etc. It can also be used for sewage discharge and river infusion. , is widely used. [0003] Slurry pumps usually use a centrifugal structure. The oil seals on the outside of the front and rear bearings at both ends of the bracket seal the lubricating oil (hereinafter referred to as engine oil) from leaking to ensure the normal lubrication of the bearings. However, when the oil seal rotates at a high speed on the pump shaft or stops the pump, there is often oil leakage, and the oil leakage of the rear bear...

AI Technical Summary

Problems solved by technology

Due to cost considerations, the current processing plant module process is often a single pump, that is, there is no spare pump, and the disassembly and maintenance of the whole pump will cause temporary shutdown

[0006] Therefore, problems such as heat generation and oil leakage of the bracket oil seal 5 not only affect production, cause production cost to rise, production efficiency to decrease, but also pollute the environment
