1984年9月我队对一台柳州第二空压机厂79年出厂的LGY20—10/7型螺杆压缩机进行探讨性修理,因该机达不到额定排气压力,先后辗转了两个地质队都长期搁置不用。经初步试车确认,做动力的柴油机性能良好,拖动压缩机额定的排气表压力达不到7kgf/cm～2,当排气表压力仅达5.2kgf/cm～2时,柴油机就因拖不动负荷在排浓烟的同时停止了运行。显然,压缩机消耗功率远远超过了所需的额定值。为了分析和查找无用功率的消耗,正确判断故障,我们对其消耗能量的分配系统进行了计算。
September 1984 I team on a second air compressor plant in Liuzhou 79 factory LGY20-10 / 7 screw compressor for exploratory repair, because the aircraft can not reach the rated exhaust pressure, has been removed two Geological teams are shelved for a long time. After preliminary test confirmed that the power of the diesel engine performance is good, drag the compressor rated exhaust pressure of less than 7kgf / cm ~ 2, when the exhaust pressure of only 5.2kgf / cm ~ 2, the diesel due to drag Immobile load in the row of smoke stopped running at the same time. Obviously, the compressor consumes power far beyond the required rating. In order to analyze and find out the consumption of unused power and correctly judge the fault, we calculated the energy consumption distribution system.
