Hydraulic pumps work on the principle of sealing volume change, so they are generally called positive displacement hydraulic pumps. The plunger is installed in the cylinder to form a sealed volume a, and the plunger is always pressed against the eccentric wheel under the action of the spring. Above, the prime mover drives the eccentric wheel to rotate to make the plunger reciprocate, so that the size of the sealed volume a changes periodically and alternately. When a changes from small to large, a partial vacuum is formed, so that the oil in the tank is under the action of atmospheric pressure. The oil suction pipe opens the one-way valve and enters the oil chamber to realize oil absorption; on the contrary, when a changes from large to small, the oil absorbed in the a chamber will push the one-way valve to flow into the system to realize oil pressure, so that the hydraulic pump will be the original The mechanical energy input by the motor is converted into the pressure energy of the liquid, the prime mover drives the eccentric wheel to rotate continuously, and the hydraulic pump continuously absorbs and presses oil.
