Embodiment Construction

[0011] As shown in FIG. 1 : the piston body 3 is composed of an upper part and a lower part, and the diameter of the upper part of the piston body 3 is smaller than the diameter of the lower part of the piston body 3 . A second or third stage piston ring 5 and a guide ring 4 are arranged on the upper part of the piston body 3 . Said secondary or tertiary piston ring 5 and guide ring 4 are respectively made of filled polytetrafluoroethylene material, wherein there are three secondary or tertiary piston rings 5 ​​and one guide ring 4 . The lower part of the piston body 3 is provided with a first-stage piston ring 2 and an oil scraper ring 1, and the first-stage piston ring 2 and the oil scraper ring 1 are made of HT250 material, wherein there are two first-stage piston rings 2, and the oil scraper ring 1 There is one.

[0012] The upper part of the present invention is a secondary piston or a tertiary piston, and the lower part is a primary piston. The first stage is lubricate...

Abstract

The invention relates to a middle-pressure compressor differential piston element, wherein the piston is formed by upper and lower parts, while the upper part is smaller than the lower part, the upper part is disposed with two-stage or three-stage piston ring and a guiding ring, and the lower part is disposed with a first-stage piston ring and a scraping ring. The invention has compact structure, low cost and small volume which can avoid oil being splashed on the upper piston ring and reduce the lubricant consumption, to reduce the oil in compressed air and pollution. And the compressed air with lubricant from the first stage in second or third compression can improve the condition on the piston ring in the second or third stage to improve the service life and function of the piston ring.

Description

technical field [0001] The invention belongs to a pneumatic component, in particular to a differential piston assembly of a medium-pressure compressor. Background technique [0002] The piston is a key component in the compressor, and the structural performance of this component directly affects the working efficiency of the compressor. Existing medium-pressure compressors usually use a piston body with a single diameter, and a piston ring and an oil wiper ring are arranged on the piston body. The piston body of the compressor with this structure has large volume, high energy consumption, high manufacturing cost, large consumption of lubricating oil during operation, and high oil content in the compressed air, which pollutes the environment. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, thereby providing a differential piston assembly of a medium-pressure compressor to reduce volume, cost and ener...
