LGY20-10/7压缩机和LGYⅡ-10/7压缩机上的最小压力阀,是在瑞典50年代生产的螺杆压缩机(9.6米~3/分)最小压力阀的基础上设计生产的。经过多年的使用实践,发现该机随着使用时间的延长,其润滑油消耗量逐渐增加,且压缩机排出的压缩空气内含有大量的雾状润滑油,使压缩空气的纯洁度下降。我们认为:这是由于最小压力阀的结构性能欠佳造成的。 The minimum pressure valves on the LGY20-10 / 7 and LGYⅡ-10/7 compressors were designed and manufactured on the basis of the smallest pressure valves in Sweden in the 1950s with screw compressors (9.6 m to 3 / min). After years of practice, it is found that the lubricating oil consumption gradually increases with the extension of the service time, and the compressed air discharged by the compressor contains a large amount of misty lubricating oil, which reduces the purity of the compressed air. We think this is due to the poor structural performance of the minimum pressure valve.
