重量法是对两列L型活塞式压缩机进行油耗测试的一种普遍应用的方法。但在油耗测试中,有时会出现在同一台压缩机进行多次测试时不但没有耗油,反而油量会增多,并视其压缩机规格大小而异的现象。本文论述了压缩机在正常工况下油量增多的原因,并提出了解决办法,解决了实际存在的技术问题,提高了测量精度,为在自检、行检和优质产品定点试验中较为准确地测量油耗创造了良好条件。
The gravimetric method is a commonly used method of fuel consumption testing of two L-piston compressors. But in the fuel consumption test, sometimes there will be multiple tests with the same compressor not only without fuel consumption, but will increase the amount of oil, and depending on the size of the compressor specifications vary. In this paper, the reasons for the increase of compressor oil quantity under normal operating conditions are discussed, and the solutions are put forward to solve the practical technical problems and improve the measuring accuracy, which is more accurate in the fixed-point test of self-inspection, inspection and quality products Measuring fuel consumption creates good conditions.
