It is controlled by ON / OFF, and it
Provide the oil quantity corresponding to the piston speed.
Can be. Especially here where stick-slip occurs
At low speeds where it is easy to
Hydraulic pump from both the main hydraulic pump and the booster pump.
When pressure oil is being supplied to the cylinder,
When the pressure oil supply from the pump is not the maximum,
This state is maintained. Therefore, the piston speed is
From the point at which the hydraulic oil supply from the
The supply of pressure oil to the cylinder is controlled by a proportional solenoid valve.
It is controlled in proportion to the deceleration gradient of the ton speed. Result type
Supply the pressure oil corresponding to the hydraulic cylinder for opening and closing
One main hydraulic pump whose oil volume is controlled by a valve and opening and closing
