Engineering plastic exhaust valve plate for compressor

Abstract

The invention relates to an engineering plastic exhaust valve plate for a compressor, which takes engineering plastic as a raw material and is molded by one-time injection. The engineering plastic consists of 60 to 85wt% of PEEK and 15 to 40wt% of glass fiber. Compared with the prior art, the invention has the advantages of reducing noise, improving the efficiency of the whole machine, prolonging life, and the like.

Description

technical field [0001] The invention relates to an exhaust valve plate, in particular to an engineering plastic exhaust valve plate for a compressor. Background technique [0002] Since the exhaust valve is an integral part of the air valve, the air valve is usually called the "heart" in the compressor, so it is conceivable that the important position of the exhaust valve in the compressor will directly affect the compressor. Power, noise and other performance parameters, so the material requirements for the exhaust valve must be very high: [0003] (1) Higher elastic modulus; From the test situation, the elastic modulus affects the refrigeration, heating efficiency and noise of the compressor. [0004] (2) Better surface stress; the existing exhaust valve plate is realized by the tumbling process, which has high requirements for equipment and tumbling technology, and the surface is prone to defects, especially products with complex shapes. It is not easy to roll and throw...

Problems solved by technology

[0003] (1) Higher elastic modulus; From the test situation, the elastic modulus affects the refrigeration, heating efficiency and noise of the compressor

[0004] (2) Better surface stress; the existing exhaust valve plate is realized by the tumbling process, which has high requirements for equipment and tumbling technology, and the surface is prone to defects, especially products with complex shapes. It is not easy to roll and throw to the required size at the corner of the step

[0008] The current metal exhaust valve plate has a good advantage in elastic modulus. According to the experiment, it is found that after the elastic modulus reaches a certain level, the impact on the overall performance of the compressor will be small, but in terms of surface treatment process There are always unstable factors; generally speaking, the higher the speed of the compressor, the harder it is to guarantee the life of the air valve, and the greater the resistance loss of the air valve may be. Therefore, the air valve is a factor that limits the high-speed operation of the compressor. Limited improvement in compressor performance
