据调查,目前国内生产的活塞式微型空压机系列产品中还有部分产品呼吸管处喷油现象很严重,致使产品耗油量大,污染工作环境,阵低了产品使用的安全可靠性。对此,一机部标准《一般用往复活塞式微型空气压缩机系列型式与基本参数》编制说明（1974）中曾经指出:“系列产品部分空压机还存在漏油、漏气及喷油现象……。呼吸管处喷油,主要是在呼吸过程中,空气中的油没有得到很好的分离就从呼
According to the survey, at present, there are still some products in the piston miniature air compressor series produced in China that cause serious fuel injection. As a result, the fuel consumption of the products is so great that it pollutes the working environment and lowers the safety and reliability of the products. In response, a machine unit standard “General Reciprocating Piston Micro Air Compressor Series Type and basic parameters,” the preparation of instructions (1974) had pointed out: "Some products also have oil leakage, leakage and fuel injection phenomenon ... Breathing tube at the injection, mainly in the breathing process, the air in the oil is not well separated from the call
