Hydraulic support is the supporting equipment in coal mining machinery, after overhaul in general can use five years, but the service life of all kinds of hydraulic valve in hydraulic support is very low, long 3 months, only a few short weeks, the way and solution is to increase system abroad filtering precision and improve the quality of the emulsion, but it is not big. In Britain, a hydraulic valve as an example, although the machining accuracy and the whole hydraulic system filtration precision is high, but because of low service life, has been facing elimination in our country. Early hydraulic support, there is no other sealing measures between kinematic pair, is direct contact with the metal seal, requiring the seal contact surface, has high machining accuracy, otherwise must increase the adhesion strength of the seal, and make the contact surface to produce plastic deformation, plug leak path. A complete hydraulic system consists of five parts, namely, power components, actuators, control components, no parts and hydraulic oil. The role of dynamic components is the prime mover can convert the mechanical energy of liquid pressure, refers to the oil pump in the hydraulic system, it supplies power to the entire hydraulic system. The structure of hydraulic pump generally have gear pump, vane pump and piston pump. Actuators ( Such as hydraulic cylinders and hydraulic motors) The role of is the liquid pressure can be converted into mechanical energy, driving load for a straight line reciprocating movement or rotational motion. Control components ( The various hydraulic valves) In the hydraulic system control and adjustment of the liquid pressure, flow and direction. According to different control function, the hydraulic valve can be divided into the village of force control valve, flow control valves and direction control valves. Pressure control valve is divided into benefits flow valve ( The relief valve) , relief valve, sequence valve, pressure relays, etc. ; Flow control valves including throttle valve, adjusting valve, shunt valve and so on; Direction control valves including one-way valve, hydraulic control one-way Industrial Valves, shuttle Industrial Valves, reversing valve, etc. According to different control mode, control valve, hydraulic valve can be divided into the switch type constant value control valve and the proportional control valve. Auxiliary components including oil tank, oil filter, oil pipe and pipe joint, seal oil temperature, oil pressure gauge, a meter, etc. Hydraulic oil is the working medium of transmit energy in hydraulic system, there are all kinds of mineral oil, emulsion and molding hydraulic oil etc. Several categories.
