Hydraulic Press

  • Description
Product Detail

Press through a one-way valve hydraulic oil in the tank makes cylinder/piston cycle acting as productivity so as to complete the mechanical movement of a mechanical, hydraulic machine. Hydraulic press through special hydraulic oil as working media, hydraulic pump as power source, pump forces hydraulic fluid through hydraulic lines into the cylinder/piston, and many groups cooperate in cylinder/piston seals, seals in different locations are different, but they all play a role in sealing, hydraulic oil cannot leak.

1, on movable Crossbeam of hydraulic machine travel speed depends on the pump for liquid, and has nothing to do with forging deformation resistance in the process. Pump for liquid quantity is constant, then press the speed is constant.

2, pump feeding pressure and consumption of power associated with the deformation resistance of the workpieces to be processed, and deformation resistance, pump for the hydraulic pressure and consumes less power, but small.

3, can be used on movable Crossbeam travel speed is constant and pump for the hydraulic pressure changes characteristic of as a distributor signal manipulation to achieve automatic control of hydraulic machines.

4, basic investment, covers an area of small, day-to-day maintenance and repair easy. Pump hydraulic pump in the direct drive system is and working pressure maximum working speed selected by the press, hydraulic liquid-filled itinerary, return, secondary operations and the required working pressure is small, the hydraulic pumps are not fully used, particularly large-tonnage hydraulic presses, its utilization factor was very low. Therefore, the press tends to speed and rated working pressure transmission
