The main components and functions of hydraulic electric pumps
inputtime：2024-09-17hits：order
The main components of a hydraulic electric pump include energy storage components and control components: the energy storage components are composed of an energy accumulator, a vibration damping container, an oil filter, a hand pump, and an oil pump. The accumulator is separated by a piston, and the upper part is usually filled with nitrogen gas. When the electric motor drives the oil pump, the oil is extracted from the oil tank and sent to the lower part of the accumulator, thereby compressing nitrogen gas and storing energy. The vibration reducing container is used to eliminate pressure fluctuations during oil pump pressurization. The oil filter ensures that the oil entering the high-pressure oil circuit is free of impurities. When adjusting and detecting hydraulic electric pump faults or when there is no power supply, the hand pump can increase or supplement pressure. The oil pump sends oil to the accumulator to store energy.
The control element is mainly composed of a valve system, which serves as the intermediate connection between the energy storage element and the executing element, providing hydraulic pulse signals for opening and closing actions to control the operating element.
