Rally machine debugging is mainly divided into the following six steps

Rally machine debugging is mainly divided into the following six steps:

1. Pull the cold-bending support to both sides equidistantly, and do not touch when moving the beam;

2. Turn off the pump motor, unscrew the MS plug on the pump, drain the air from the pump (flow out with a small amount of oil), drain the air and return to the plug: start the pump and lift the piston repeatedly to drain the air in the cylinder and tubing. net.

3, check the oil pipe joints with or without oil leakage;

4. Install a spherical lower platen on the platen, and lift and move the beam so that the upper and lower platens are separated by about 20mm;

5, start the pump, close the return valve to open the delivery valve to make the platen rise, slowly increase the pressure;

6. If there is oil leakage, tighten the oil joint after discharge.
