油泵是工程机械的心脏部件。过去检测油泵的磨损程度常靠测定油泵流量及油压的变化以及凭操作人员的直觉经验来判断。这种方法往往不能及时发现油泵内部的一些异常现象,因而油泵隐患常导致故障。为了能早期发现油泵内部的隐患并推断出油泵还能继续保持多长的工作寿命,日本建机株式会社研制成功油泵故障早期诊断器。它可 Pump is the heart of construction machinery parts. In the past, the degree of wear on a pump was often determined by measuring changes in pump flow and pressure, as well as by the operator’s intuitive experience. This method often can not promptly find some abnormal internal pump, oil pump hidden trouble often lead to failure. In order to early detection of hidden dangers within the pump and infer the pump can continue to maintain long working life, Japan’s Construction Machinery Co., Ltd. successfully developed pump failure early diagnosis. It can be
