In the hydraulic drive system, which is the power element
Execution component (oil cylinder, hydraulic motor) : it is the hydraulic energy that converts liquid to mechanical energy. In this case, the oil cylinder does a straight line and the motor spins.
Auxiliary components: other components besides the above three parts, including pressure gauge, oil filter, storage device, cooler, pipe and tank. I hope my answer will help you
Control components: including 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.
In hydraulic transmission system, the power element is hydraulic pump, actuator and hydraulic cylinder. Hydraulic system is mainly composed of: power components (pump), executive components (cylinder or hydraulic motor), control components (valves), auxiliary components and working medium of five parts. Power element (oil pump) : its function is to convert liquid into liquid pressure energy using mechanical energy of the original motive. It's the power part of the hydraulic drive.
