Energy-saving and environment-friendly water lubrication single-screw host

Abstract

The invention provides an energy-saving and environment-friendly water lubrication single-screw host. The energy-saving and environment-friendly water lubrication single-screw host is characterized in that the sealing property between a bearing and a main shaft as well as a housing is better, a special heat dissipation structure is arranged at the interior of a machine, the high-temperature phenomenon during operation is avoided, and the operation is relatively stable; a front bearing mechanical seal and a rear bearing mechanical seal are also respectively mounted at the front end and the rear end of the main shaft; a front vacuum cavity is formed between the front bearing mechanical seal and a front bearing; a rear vacuum cavity is formed between the rear bearing mechanical seal and a rear bearing; a front mechanical seal cooling water inlet and a rear mechanical seal cooling water inlet are also respectively formed in the housing; the front mechanical seal cooling water inlet is connected with a first cooling water channel which coils from the front end of the main shaft to the rear end, then coils back to the front end from the rear end and is connected to the front bearing mechanical seal; a water returning channel of the first cooling water channel is formed in the housing; the rear mechanical seal cooling water inlet is connected with a second cooling water channel; a water returning channel of the second cooling water channel is formed in the housing.

Description

technical field [0001] The invention relates to a component of an air compressor, in particular to an energy-saving and environment-friendly water-lubricated single-screw main engine. Background technique [0002] Air compressor is the basic product of industrial modernization. It is often said that electrical and automation have the meaning of full pneumatic; and air compressor is to provide air source power, which is the main body of the electromechanical air source device, which is the core equipment of the pneumatic system. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a gas pressure generating device for compressed air. There are many types of air compressors, which can be divided into volumetric compressors and speed compressors according to the working principle. The working principle of the positive displacement compressor is to compress the volume of the gas, so that the density of ...

AI Technical Summary

Problems solved by technology

The inventor of this patent application found in practice that the single-screw main engine in the prior art has the following disadvantages: 1. The seal between the bearing, the main shaft and the housing is not good, and the bearing is easy to enter water, resulting in a low service life of the bearing , resulting in frequent host failures

2. There is no effective heat dissipation structure in the host, and the host is prone to high temperature when it is working, resulting in a short service life of the host
