Control method of Hydraulic Variable Displacement Piston Motor products
The variable of Hydraulic Variable Displacement Piston Motor products is similar to the variable of the axial piston pump, which is realized by changing the inclination angle of the swash plate or the swing angle of the inclined shaft.
The variable of Hydraulic Variable Displacement Piston Motor products is similar to the variable of the axial piston pump, which is realized by changing the inclination angle of the swash plate or the swing angle of the inclined shaft. The method of electro-hydraulic control is often used. The speed sensor or pressure sensor feeds back the changing speed or pressure to the electro-hydraulic proportional valve or servo valve to control the movement of the variable piston of the motor and realize the constant speed or constant pressure control of the hydraulic motor. This kind of control is easy to carry out the dynamic correction of the adjustment process, and can complete the best control with the help of a microcomputer. In order to make the motor make full use of the power of the prime mover in the variable process of high-speed small torque and low-speed high torque, a constant power variable motor can be used.
In the constant current source system (that is, the flow rate of the pump source is basically constant), as long as the pressure difference between the inlet and outlet of the motor remains unchanged, the constant power control of the motor can be achieved approximately.
The constant power variable principle of Hydraulic Variable Displacement Piston Motor products. The variable piston of the two-way variable motor 2 is controlled by the constant pressure control valve 5 . If the load torque of the motor increases for some reason, when the motor displacement has not changed in the constant current source system, its inlet pressure must increase. This pressure acts on the end of the spool of the constant pressure control valve 5, overcomes the spring force to move the spool to the left, and the piston of the variable cylinder 1 moves to the left to increase the displacement of the motor, so the inlet pressure of the motor decreases.
