factory direct sale variable displacement axial piston pump 10PCY14-1B 10PCY

This series of axial piston pumps will have a 31.5 MPa pressure of pure hydraulic oil into a variety of hydraulic systems such as hydraulic press, hydraulic motor, to generate tremendous power.

At the same time, the oil pump can be used as a hydraulic motor. According to the need, the oil pump has a variety of variable forms. The oil pump and motor are widely used in various machinery of ship, aviation, mine, metallurgy, die casting, forging and machine tool. Its characteristics are small size, high efficiency, long life, advanced design, compact structure and convenient maintenance.

When the output pressure of this variable type pump is less than the constant pressure, the full displacement output pressure oil, i.e. the quantitative output, automatically adjusts the pump flow when the output pressure reaches the set pressure, so as to maintain the constant pressure and meet the requirements of the system. The output constant pressure value of the pump can be steplessly adjusted within the range of pressure regulation according to the need. The structure of the pump is shown in the figure above. The output pressure oil is simultaneously connected to the control oil inlet of the variable piston lower chamber and the constant pressure valve. When the output pressure is less than the constant pressure, the oil pressure thrust acting on the constant pressure valve core is less than the spring force. The constant pressure valve is in the open state. The pressure oil enters the variable piston upper chamber. The variable piston pressure is in the low position of zui, and the total output pressure oil of the pump is: When the pump is working at the regulated pressure, the oil pressure thrust acting on the constant pressure valve core is equal to the regulated spring force. The inlet and outlet of the constant pressure valve are in the open state at the same time, so that the oil pressure thrust of the variable piston's upper and lower chambers is equal. The variable piston balances at a certain position. If the hydraulic damping (load) increases, the oil pressure increases instantaneously, the outlet of the constant pressure valve opens large, the inlet closes small, and the variable activity. Compared with the lower chamber, the pressure of the upper chamber decreases, the variable piston moves upward, and the flow rate of the pump decreases until the pressure drops to a constant pressure. At this time, the variable piston works in a new equilibrium position. On the contrary, if the hydraulic damp (load) decreases, the oil pressure drops instantaneously, the constant pressure valve inlet opens larger, the discharge outlet closes smaller, the oil pressure of the variable piston upper chamber is higher than that of the lower chamber, the variable piston moves downward, and the flow rate of the pump increases until the pressure rises to the constant pressure.
