[0002] Hydraulic power element refers to the oil pump in the hydraulic system, also known as the power element. The main function of the hydraulic power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, thereby providing power for the entire hydraulic system. The power element is usually driven by an engine or an electric motor, sucking oil from the hydraulic oil tank, forming pressure oil and then discharging it and sending it to the actuator. In order to expand the operating space inside the hydraulic power element and strengthen its own rigidity, welding is generally used during processing.
