英文摘要	The feasibility of filling PTFE composite material as the material of the top seal of scroll compressor was studied. Taking a certain type of scroll compressor as an example, had established a mathematical model of sealing strip force, and analysed the change regularity of sealing strip load. The PES, PEEK, the pure PTFE and the Filled PTFEwere respectively matched with the HT250. According to the running parameters of scroll compressor, had designed test conditions, and had carried out the simulation experiment in the end wear testing machine. According to the experimental results, analyzed the four materials of the tribological properties. The volume wear rate, friction coefficient and temperature change of PTFE composites were measured. The morphology of the friction surface and the transfer of composites were observed by scanning electron microscopy. The results show that when the experimental conditions are 200N and 2000r/min, the friction coefficient of friction pairs is less than 0.25, and the volume wear rate is 3.328 ∗ 10-6. When the temperature increases, the friction coefficient has a rising trend, but it rises slowly. In addition, it is found by scanning electron microscope that when the temperature is above 120 degrees, the material will burn and the wear will be intensified. In summary, compared with the actual working conditions of scroll compressor, the PTFE material is used as the sealing strip material, and its friction and wear properties can basically meet the needs of the work. © Published under licence by IOP Publishing Ltd.
