The role of a hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuating components, control components, auxiliary components (accessories) and hydraulic oil. Hydraulic systems can be divided into two categories: hydraulic transmission systems and hydraulic control systems. Hydraulic transmission system to transfer power and movement as the main function. Hydraulic control system is to make the hydraulic system output to meet the specific performance requirements (especially dynamic performance), usually referred to as the hydraulic system mainly refers to the hydraulic transmission system.
Scraper hydraulic system
A complete hydraulic system consists of five parts, namely, power components, executive components, control components, auxiliary components (accessories) and hydraulic oil.
Power components: The role of power components is to convert the mechanical energy of the prime mover into liquid pressure energy, refers to the hydraulic system of the oil pump, which provides power to the entire hydraulic system. Hydraulic pump structure form generally have gear pumps, vane pumps, piston pumps and screw pumps.
Execution element: the role of the execution element (such as hydraulic cylinders and hydraulic motors) is to convert the pressure of the liquid into mechanical energy, drive the load for linear reciprocating motion or rotary motion.
Control elements: control elements (i.e., a variety of hydraulic valves) in the hydraulic system to control and regulate the pressure, flow and direction of the liquid. According to the different control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Pressure control valves include relief valves (safety valves), pressure reducing valves, sequence valves, pressure relays, etc.; flow control valves include throttle valves, adjustment valves, shunt collector valves, etc.; directional control valves include check valves, hydraulic check valves, shuttle valves, reversing valves, etc. According to the different control methods, hydraulic valves can be divided into switching control valves, fixed value control valves and proportional control valves.
Auxiliary components: auxiliary components include oil tank, oil filter, cooler, heater, accumulator, oil pipe and pipe joint, seal, quick-change joint, high-pressure ball valve, hose assembly, pressure measuring joint, pressure gauge, oil level meter, oil thermometer, etc.
