Oil-free lubricating seal is a reliable partner for non-polluting industries such as food and medicine. It is the key to solving the problem of non-leakage, good wear resistance and long continuous operation cycle of compressors. It is the key measure for environmental protection, energy saving and consumption reduction. The company has formed a proprietary standard and achieved new results of sealing 4,000 hours of operation at 32 MPa. It has won the first prize of Shenyang Science and Technology Achievements and the National Silver Medal of 2Z3/8-1 Oil-free Lubricating Compressor. , "High Pressure Seal" Liaoning Province Science and Technology Second Prize, a number of awards. With professional technology and rich experience in compressors, it can meet the design and manufacturing tasks of medium and high pressure and flammable and explosive gases at home and abroad. It can produce piston rings, support rings and packing rings of various specifications below φ1400. Now it is responsible for design and manufacturing tasks for some manufacturers in the compressor industry.

The PEEK series is our technical high point. In 1985, international friends introduced us to the new material PEEK which has been used as a compressor valve disc. In 1986, after cooperating with Changchun Institute of Applied Chemistry for three years, it was successfully completed and introduced to the market, becoming the first company to introduce PEEK and products into China. In 2001, Changchun Airlines Special Materials Technology Co., Ltd. was established. In view of the harsh working conditions of high-pressure compressors, we have designed special material formulations for piston rings and other related seals. After years of application, PEEK has entered the high temperature and high pressure forbidden zone. Although the working conditions are different, its life span is double that of PTFE. increase. The main products: valve, piston ring, horizontal support ring, throttle ring, choke ring, star wheel, centrifugal compressor shaft seal, military products, etc., can design and produce related products below φ400.

With the advancement of technology, the problem of gas valve leakage, gas stringing and short life has been significantly improved, but it is still called one of the three major wearing parts.

● Master the law of valve movement and combine theory with experience

● Optimize combination matching and obtain reasonable design data, which is the key to valve design

●Selecting high-quality materials and reasonable process is the continuation of optimized design

●Good performance, low airflow resistance, low power consumption and long life are our pursuit
