Hydraulic pump is a kind of hydraulic component that provides pressurized liquid for hydraulic transmission. Its function is to convert the mechanical energy of power machine (such as motor and internal combustion engine) into the pressure energy of liquid. The working principle of the single plunger pump is that the cam is driven by the motor to rotate. When the cam pushes the plunger upward, the sealing volume formed by the plunger and the cylinder block decreases, and the oil is squeezed out of the sealing volume and discharged to the required place through the one-way valve. When the cam rotates to the lower part of the curve, the spring forces the plunger downward to form a certain vacuum, and the oil in the tank enters the sealing volume under the action of atmospheric pressure. The cam makes the plunger continuously rise and fall, the sealing volume decreases and increases periodically, and the pump continuously absorbs and discharges oil.
