Problems solved by technology

[0008] Although these materials have a small friction coefficient, they have a small elastic modulus and poor deformation resistance, and cannot maintain the machining accuracy of the star wheel for a long time, which affects the meshing life of the screw star wheel
In addition, PEEK resin can only rely on imports at present. It is expensive, as high as 1 million / t, and the material cost of each star wheel reaches 1,000-2,000 yuan. Because the star wheel is easy to wear, this greatly increases Manufacturing costs and maintenance costs

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] It can be seen from Fig. 4A, Fig. 4B, and Fig. 4C that the present invention includes: the inner layer is an alloy steel core plate 200, and the outer layer is a PEEK carbon fiber polymer 300; the PEEK carbon fiber polymer 300 is covered on the alloy steel core plate 200, and firmly bond with it.

[0025] According to the meshing surface of the star wheel and the screw, the present invention designs and manufactures a steel core plate, heat-treats the core plate to increase its rigidity, and makes a corresponding meshing surface, and molds a layer of PEEK carbon fiber polymer on the outside of the core plate. The core plate must be preheated, and the temperature should be as close as possible to the crystallization temperature of PEEK carbon fiber polymer. Qualitative treatment is carried out after fabrication and shaping. The qualitativ...

Abstract

The invention relates to a compound star wheel sheet for single screw compressor, which is characterized in that the compound star wheel sheet comprises an alloy steel core plate in the inner layer (200) and a PEEK carbon fiber polymer (300) in the outer layer. The PEEK carbon fiber polymer (300) is covered on the alloy steel core plate (200) and is combined with the alloy steel core plate (200). The invention has the advantages that the star wheel sheet rigidity, strength and deformation resistance capability resistance are increased, the meshing precision of the star wheel sheet and the life-span of the host are improved, the producing cost is greatly reduced and the benefit is increased.

Description

technical field [0001] The invention relates to a single-screw compressor, in particular to a star wheel plate in the single-screw compressor. Background technique [0002] Single-screw compressor is a widely used fluid machine, used to compress gas, so as to increase the gas pressure. It is mainly used for gas synthesis in the chemical industry; catalysis, cracking, desulfurization, and hydrogenation control in petroleum refining; drilling and gas injection in oil fields in the oil production industry; coke oven gas hydrogen separation in the iron and steel industry; air conditioning, Freezing, refrigeration; gas transportation, gas separation; and widely used in aerodynamic fields, such as wind machinery, instrument control, vehicle braking, spraying, spraying and military weapon systems. [0003] Single-screw compressors have a series of advantages such as reliable operation, low noise, low vibration, energy saving, long life, less maintenance and low cost, and are calle...
