Hydraulic Components

Do you feel that there are too many hydraulic components, too complicated to organize? This article will carefully sort out and lead you to quickly understand the classification of hydraulic components. Of course, if you think it’s too troublesome, you can go directly to our Elephant Fluid Power store to search for hydraulic parts. We have listed some combinations of parts specially used for repair or replacement for you to choose from.


First of all, you need to know that a complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components and working medium.


  1. Power components

    Its role is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. Power components refer to the hydraulic pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps, plunger pumps, and screw pumps.

  2. Actuators components

    The function is to convert the pressure energy of the liquid into mechanical energy, and drive the load for linear reciprocating motion or rotary motion. The actuators are hydraulic cylinders and hydraulic motors.

  3. Control components

    To put it bluntly, it is all kinds of hydraulic valves. Control and regulate the pressure, flow and direction of liquids in hydraulic systems. 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 are further divided into relief valves (safety valves), pressure reducing valves, sequence valves, pressure relays, etc.; Flow control valves include throttle valves, adjustment valves, diverter collector valves, etc.; Directional control valves include check valves, hydraulic control check valves, shuttle valves, directional valves, etc. According to different control methods, hydraulic valves can be divided into on-off control valves, fixed value control valves and proportional control valves.

  4. Auxiliary components

    It includes accumulators, filters, coolers, heaters, oil pipes, pipe joints, oil tanks, pressure gauges, flow meters, sealing devices, etc., which play auxiliary roles such as connection, oil storage, filtration and measurement of oil pressure, please refer to "Hydraulic Transmission" and "Hydraulic System Design Series".

  5. Working medium

    It refers to the hydraulic oil or emulsion in all kinds of hydraulic transmission, and there are various categories of mineral oil, emulsion and synthetic hydraulic oil. It is through which the hydraulic system realizes motion and power transmission.

    After reading the above introduction, do you have a clearer understanding of hydraulic components? If you have this need, Elephant Fluid Power provides all the above hydraulic components except the working medium, providing you with one-stop hydraulic pump and parts replacement services.
