People have devised by the hydrostatic forging machine of accumulator independent oil supply thus, are meeting the various operating modes of hydrostatic forging machine
On the basis of, the configuration of pump is reduced to the maximum extent, to reach energy saving, is finally reached the purpose for reducing cost.But this sets
Accumulator provides power oil using nearly constant pressure to hydrostatic forging machine in meter, and hydrostatic forging course of work drag is continuous
It changes, the energy that pressure oil loses when hydrostatic forging machine drag is smaller is larger, is even resulted in sometimes by accumulator independence
The method of fuel feeding loses more than gain.If realizing pressure regulation using valve arrangement is added, not only effect is undesirable can also limit press
The operation linear velocity of work.
