工程塑料近年来在化工机械配件上以及压缩机无油润滑等方面已经得到广泛应用。我省采用工程塑料代替金属活塞环,实现无油润滑从七○年开始已在循环机、氮氢压缩机的低压段(一、二、三段)进行使用和推广。根据几年来的实践证明:循环机及氮氢压缩机低压段,采用厦门化工修配厂生产的尼龙6活塞环效果很好,使用寿命高达一年以上。然而高压段(四、五段)由于压力高、压差较大,温度也较高,究竟采用什么材质活塞环更为合
In recent years, engineering plastics in chemical machinery parts and compressors, such as oil-free lubrication has been widely used. Engineering plastics in our province to replace the metal piston rings, to achieve oil-free from 70 years have been in the cycle, the nitrogen-hydrogen compressor low pressure section (one, two, three sections) for use and promotion. According to the practice over the past few years, it has been proved that the low-pressure section of the recycle machine and the hydrogen-nitrogen compressor works well with the nylon 6 piston ring produced by Xiamen Chemical Equipment Factory and the service life is as high as one year or more. However, the high-pressure section (four, five) due to high pressure, large pressure, temperature is higher, what kind of material is more suitable piston ring
