【摘要】 研制了基于示功图法的往复空压机气阀故障测试系统。首先介绍了应用示功图法判断气阀故障的基本原理,研究了引压通道的选取问题。引压通道开孔于气阀盖上,合理确定其直径,避免产生通道共振。然后详细介绍了基于LabVIEW的测试系统总体方案、硬件构成及相关控制软件,最后通过试验验证了系统的可行性和有效性。更多还原

【Abstract】 A fault test system for reciprocating compressor valves by means of indicator diagram is developed.The principle of valve fault diagnosis using indicator diagram is introduced,and the selection of the diameter of testing pressure channel is discussed.The channel is opening in the valve cover,and the diameter needs to be rationally determined to avoid channel resonance.Then this article elaborates the overall system program which is developed based on LabVlEW,hardware structure and associated control software.At last,the feasibility and effectiveness of the system are verified by the experimentation.更多还原
