Problems solved by technology

[0004] The star wheel meshes with the cylindrical screw by a molded line. During the long-term operation of the machine, the wear of the molded line will lead to gas leakage, so as time goes by, the gas production of the machine will become smaller and smaller.

Abstract

The invention discloses a manufacturing method for a carbon fiber star wheel sheet. The service life of the carbon fiber star wheel sheet produced and manufactured through the method is prolonged andthe superiority for utilization is provided. The manufacturing method for the carbon fiber star wheel sheet comprises the following steps: (1) cleaning and preparing molds: mounting an upper mold anda lower mold on a tool and cleaning the upper mold and the lower mold, so as to prevent dust and impurities from being remained; (2) coating a pore sealing agent; (3) adhering a sealing adhesive tapeand coating a de-molding agent; (4) cutting a carbon fiber fabric and immersing the carbon fiber fabric into a resin matrix to form a carbon fiber prepreg; overlaying the carbon fiber prepreg layer bylayer and carrying out pre-compaction; and (5) putting the carbon fiber prepreg overlaid in step (4) into the upper surface of the lower mold and carrying out mold assembling; and heating through a heating pipe and molding in one step after certain time and at certain temperature, wherein the heating pipe is connected with a heating pipe system and is externally connected with a constant-temperature temperature controller.

Description

technical field [0001] The invention belongs to the technical field of a star wheel, and in particular relates to a manufacturing method of a carbon fiber star wheel. Background technique [0002] In 1960, B.Zimmern of France produced the first CP single-screw prototype. Its basic structure consists of a cylindrical screw and 2 pairs of star wheels; cylindrical screws usually have 6 screw grooves for each star wheel It separates the upper and lower spaces to realize the working process of the compressor respectively. Because of the two pairs of star wheels, the single-screw compressor is equivalent to a six-cylinder double-acting piston compressor. There is a screw shaft in the middle of the cylindrical screw, which is driven by the motor to form the process of suction and compressor exhaust. The structure of the star wheel is a floating type, and the structure of the star wheel is a star wheel body (generally made of metal) and a star wheel sheet (generally PEEK in China a...
