Labyrinth sealing structure of industrial labyrinth compressor

Abstract

The invention comprises an air cylinder, are disposed in which an air cylinder cavity and a piston jacket. On both sides of the air cylinder cavity there are air cylinder walls, on which is disposed a labyrinth groove volume room and on the piston jacket are disposed throttle port and a volume room. The piston jacket and the air cylinder walls are separated to form small gaps.

Description

A technical field [0001] The invention relates to a structure of an industrial compressor, in particular to a labyrinth sealing structure of an industrial labyrinth compressor. Two background technology [0002] Piston compressors are general-purpose machinery widely used in various industries. In order to effectively compress the medium gas, the traditional piston compressor works by the reciprocating motion between the piston ring on the piston and the cylinder, as well as the piston rod and the sealing ring in the packing. The relative movement in contact with each other creates friction and material wear. In order to reduce friction and wear, lubricating oil is injected on the contact surface, and the injection of oil pollutes the compressed medium and consumes a large amount of lubricating oil, and the separation and drainage of oil also pollutes the environment. At present, although a self-lubricating material is widely used to manufacture piston rings and sealing ri...

AI Technical Summary

Problems solved by technology

In order to reduce friction and wear, lubricating oil is injected on the contact surface, and the injection of oil pollutes the compressed medium and consumes a large amount of lubricating oil, and the separation and drainage of oil also pollutes the environment

At present, although a self-lubricating material is widely used to manufacture piston rings and sealing rings, and lubricating oil is cancelled, the wear caused by contact friction still exists.

Piston rings and sealing rings are vulnerable parts and must be replaced regularly, which increases the maintenance workload and operating costs of the compressor. At the same time, the worn-out tiny particles still exist in the gas and pollute the compressed medium. The requested gas is not allowed

[0003] Existing problems: 1. Contamination of the lubricating oil in the cylinder to the compression medium consumes a large amount of lubricating oil, and the separation and drainage of the oil also pollutes the environment; 2. The contact frictional movement of the piston ring causes wear and tear. Tiny particles still exist in the gas and pollute the compressed medium; 3. The piston ring is a vulnerable part and must be replaced regularly, which increases the maintenance workload and operating cost of the compressor
