针对矿山机械广泛应用的液压系统,笔者采用环状静电传感器,利用油微弱的带电量对矿山机械设备液压系统吸油管路故障进行监测。并建立试验系统,对液压系统吸油过程进行模拟,根据被测信号对液压系统油路输送过程进行监测及诊断。试验结果表明,环状静电传感器可对液压系统油路进行监测。
For the hydraulic system widely used in mining machinery, the author uses a ring-shaped electrostatic sensor, the use of oil with a weak charge on the mining machinery and equipment hydraulic system suction line fault monitoring. And a test system is established to simulate the process of oil absorption in the hydraulic system. According to the measured signal, the oil system of the hydraulic system is monitored and diagnosed. Test results show that the ring electrostatic sensors can be hydraulic system hydraulic circuit monitoring.
