Hydraulic machine pump direct drive of the following characteristics

1, the travel speed of the hydraulic press machine depends on the amount of the pump, and the deformation resistance of the forging is not related to the process. If the amount of the pump is constant, the working speed of the oil press is constant.

2, the pressure of the pump and the power consumption and the deformation of the workpiece to be processed, work deformation resistance, the pump pressure and power consumption is also large, and vice versa.

3, can use the active beam stroke speed constant and pump for liquid pressure change characteristics, as the control of the signal to the distributor, in order to realize the automatic control of oil pressure machine.

4, basic investment province, small area, daily maintenance and maintenance simple. Pump direct drive system in the hydraulic pump is the maximum working speed and working pressure, and the oil press in the full hydraulic stroke, return, auxiliary processes and the required work pressure, hydraulic pumps are not fully utilized, especially the large tonnage of oil pressure machine, its use is very low. Therefore, the hydraulic pressure machine tends to the work speed and the working pressure to carry on the classification transmission
