What are the hydraulic components?
Control component: directional control valve, one-way valve, reversing valve; Pressure control valve: relief valve, pressure reducing valve, sequence valve, pressure relay, etc. Flow control valve: throttle valve, governor valve, shunt valve; Auxiliary components: accumulators, filters, coolers, heaters, tubing, pipe joints, fuel tanks, pressure gauges, flowmeters, sealing devices, etc. Edit this section of the system of power components (pump), executive components (cylinder or hydraulic motor), control components (valves), auxiliary components and working medium of five parts. The function of the power element (oil pump) is to convert the liquid from the mechanical energy of the original motive to the liquid pressure energy. It's the power part of the hydraulic drive. The actuator (oil cylinder, hydraulic motor) is the hydraulic energy that converts liquid to mechanical energy. In this case, the oil cylinder does a straight line and the motor spins.
The hydraulic components can be divided into two types: dynamical and control elements and actuators. Although is hydraulic components, their own features and technical requirements of the installation and use are also different, are introduced respectively as follows: dynamic components: gear pump, vane pump, plunger pump, screw pump (power element refers to all kinds of hydraulic pump. 1 series, gear pumps and pump (including external gear and internal gear) two kind of structural type. 2, vane pump (including single pump, the variable pump, double pump, double pump). 3, plunger pump, is divided into axial radial piston pump, plunger pump and axial piston pump with quantitative pump, variable pump, (variable volume pump is divided into manual and pressure compensation variables, servo variable etc) from the structure is divided into face oil distribution and valve type with two types of oil distribution, oil and oil distribution types of radial piston pump, basically for the valve type oil distribution.) ; Execution component: hydraulic cylinder, piston hydraulic cylinder, plunger hydraulic cylinder, oscillating hydraulic cylinder, combined hydraulic cylinder; Hydraulic motor: gear hydraulic motor, blade hydraulic motor, plunger hydraulic motor.
Control elements include pressure valves, flow valves and direction valves. Their function is to adjust the speed of the fluid motivation according to the need, and control the pressure, flow and flow direction of the fluid in the hydraulic system. 4, auxiliary components Besides the above three parts of other components, including the pressure gauge, oil filter, energy storage device, cooler, pipe fittings {mainly includes: all kinds of pipe joint (flaring type, welding type, card type, sae flanged), high pressure ball valve, quick change connectors, hose assembly, pressure joints, pipe clamp, etc} and the fuel tank and so on, they are also very important. The medium of work medium is the hydraulic oil or emulsified liquid in various hydraulic transmission, which is converted by oil pump and liquid motive. Hydraulic valve is a kind of operation automation components with pressure oil, it is with pressure oil pressure valve control, usually with electromagnetic valve combination, can be used for remote control of hydropower station, oil, gas, water piping system on and off. It is used to reduce and stabilize the hydraulic pressure of a certain branch in the system, often used in the oil road of clamping, controlling and lubrication. There are direct motion and leading, multi-purpose. The classification of hydraulic pipe hydraulic hose, high pressure ball valve, intention of fast joints, pipe connector of cutting sleeve type, welded pipe, high pressure hose. The difference between hydraulic pipe joints and ordinary pipe joints
