Working principle of double acting hydraulic Hand grout pumps china :
The cam rotates through the motor. When the cam pushes the plunger upward, the seal volume formed by the plunger and cylinder block decreases and the oil is extruded from the sealing volume. When the cam rotates to the falling portion of the curve, the spring forces the plunger down to form a certain degree of vacuum. The oil in the tank enters the seal volume under the action of atmospheric pressure. The cam causes the plunger to rise and fall continuously, the seal volume decreases and increases periodically, and the pump continuously absorbs and drains the oil.
