Air suction corrugated pipe for compressor and machining method of air suction corrugated pipe

Abstract

The invention discloses an air suction corrugated pipe for a compressor. The air suction corrugated pipe comprises, by weight, 70-80 parts of ethylene propylene diene monomer rubber, 20-30 parts of butyl rubber, 4-8 parts of activating agents, 2-4 parts of anti-aging agents, 20-30 parts of carbon black, 12-16 parts of vulcanizing agents, 4-6 parts of plasticizers, 6-10 parts of nano-zinc oxide, 2-4 parts of coupling agents, 4-6 parts of zinc methacrylate, 5-8 parts of coumarone resin and 6-12 parts of pottery clay. The coupling agents, the nano-zinc oxide and the zinc methacrylate are added, inorganic fillers are uniformly dispersed inside the rubber, so that rubber materials have good shock absorption property, weather resistance and durability, mechanical-physical properties and the aging resistance of the rubber materials can be improved by the coumarone resin, sulfur can be dissolved, dispersion of the sulfur and the carbon black is facilitated, scorching is prevented, and product quality is good. The corrugated pipe has good high-temperature resistance, low-temperature resistance, weather resistance, sealability and mechanical property and is superior in shock resistance, good in sound absorption effect and long in service life.

Description

technical field [0001] The invention relates to the technical field of manufacturing rubber bellows, in particular to a suction bellows for a compressor and a processing method thereof. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and stretching. Bellows mainly include metal bellows, which are used to compensate pipeline thermal deformation, shock absorption, absorb pipeline settlement deformation, etc., and are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries. However, due to the limitations of the metal pipe's tightness, acid and alkali resistance, and weather resistance, non-metallic bellows play an irreplaceable role in the fields of medium transmission, power threading, machine tools, and home appliances. [0003] The bellows in the existing compressors are generally installed on the suc...

Problems solved by technology

However, the sealing, aging resistance, acid and alkali resistance, heat resistance and cold resistance of the existing bellows for compressors are poor, which greatly reduces the service life; and the traditional bellows have weak seismic performance and do not have good performance.
