Application of pressure and inclination sensor in hydraulic support of coal mining machinery

The hydraulic support is the supporting equipment for the coal mine comprehensive mechanized coal mining face and the key equipment for fully mechanized mining. Under the urgent need of the national coal mine safety production situation, more and more hydraulic support manufacturers are beginning to increase the investment in electro-hydraulic control systems.

The hydraulic support electro-hydraulic control system is a system that has an electronic device such as a single chip microcomputer, a sensor, and a hydraulic circuit control component, and can control the automatic movement of the hydraulic support according to production needs. The sensor part is mainly a pressure sensor and a tilt sensor.

The pressure sensor is used to detect the pressure values ​​of the front and rear pillars of the hydraulic support and the front extension beam; the inclination sensor is used to detect the inclination angle values ​​of the X-axis and the Y-axis of the hydraulic support horizontal plane.

Common hydraulic support electro-hydraulic control system for pressure and inclination sensor general requirements: pressure measurement range: 0 ~ 60 MPa, more than 2 times overpressure capability; inclination measurement range: ± 30 °, dual axis; detection accuracy: ± 1%
