The function of a manual hydraulic pump is to convert the mechanical energy of a power machine (such as an electric motor and an internal combustion engine) into the pressure energy of a liquid.
Working principle: The cam is driven by an electric motor to rotate. When the cam pushes the plunger upward, the sealing volume formed by the plunger and the cylinder body decreases, and the oil is squeezed out of the sealing volume and discharged to the desired place through the one-way valve. When the cam rotates to the falling part of the curve, the spring forces the plunger downwards, forming a certain degree of vacuum, and the oil in the tank enters the sealed volume under the action of atmospheric pressure. The cam continuously raises and lowers the plunger, periodically reducing and increasing the sealing volume, and the pump continuously sucks and discharges oil.
