YUKEN A3H Series High Pressure Hydraulic Piston Variable Displacement Pump A3H180-FR09-55A4K-10

YUKEN variable displacement piston pump is an important device in the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder block to change the volume of the sealing working chamber to achieve oil absorption and pressure. The plunger pump has high rated pressure, compact structure Due to its advantages of high efficiency and convenient flow regulation, it is widely used in high-pressure, high-flow, and flow regulation situations, such as hydraulic presses, construction machinery, and ships. The pressure oil from the YUKEN variable piston pump of Nippon Oil Research Corporation enters the lower cavity of the variable piston housing through the one-way valve through the oil passage holes in the pump body and pump housing. When the pull rod moves downward, it pushes the servo piston downward, The upper valve port of the servo valve is open, The pressure oil in the lower chamber of the variable housing enters the upper chamber of the variable housing through the oil passage hole in the variable piston. As the area of the upper chamber is larger than the lower chamber, the hydraulic pressure pushes the piston downward and drives the pin shaft

The pressure oil in the lower chamber of the variable housing enters the upper chamber of the variable housing through the oil passage hole in the variable piston. As the area of the upper chamber is larger than the lower chamber, the hydraulic pressure pushes the piston downward and drives the pin shaft
Rotate the variable head around the center of the steel ball,
Changing the tilt angle of the variable head increases the flow rate of the plunger pump. On the contrary, when the pull rod moves upward, the tilt angle of the variable head changes in the opposite direction, and the pump flow also changes
It changes accordingly. When the tilt angle becomes zero,
The variable head changes in the direction of negative deflection angle, the liquid flow changes direction, and the inlet and outlet of the pump change.
