| description | The electromagnetic pilot valve is one of the core components for realizing unmanned mining in the fully mechanized working face. The current mine electromagnetic pilot valve test methods use emulsion pump as a liquid source. The power consumption is large. In addition, the system pressure regulation uses manual adjustment, which is inefficient. In order to solve the above problems, a low-power test platform for reversing characteristics of mine electromagnetic pilot valve is designed. The platform consists of two parts: hydraulic system and measurement and control system. The hydraulic system mainly includes electric proportional valve, gas-liquid booster pump, valve to be tested, and accumulator. The double-headed gas-liquid booster pump is used as the liquid source so as to reduce energy consumption. The electric proportional valve is used to adjust the inlet air pressure of the gas-liquid booster pump. The inlet pressure of the tested valve is adjusted to the required value to realize the automatic regulation of the system pressure. The measurement and control system consists of upper computer, acquisition card, program control power supply, electric proportional valve controller (PID controller), and various sensors. According to the requirements of sensor installation and precision, the laser displacement sensor is selected to test the displacement of the electromagnet ejector rod. The PID controller is used to adjust the pressure of the liquid inlet of the electromagnetic pilot valve. The platform can realize the real-time dynamic monitoring and data storage of various performance indexes of the electromagnetic pilot valve in the reversing process. The indexes include voltage, current, inlet and outlet pressure, ejector rod displacement, dynamic response time and real-time power consumption, etc. The maximum power is only 800 W, which improves the test safety and efficiency, greatly reduces the system energy consumption, and provides an efficient and reliable test and verification means for researchers. |
