Shearing machine repair and maintenance

First, the circuit cannot afford to build pressure, upper blade holder no action;
 a. solenoid valve electrical plug connection is bad.
 b/> check the electrical plug. solenoid valve is jammed by debris or napped surface will not move.
c. combination valve damping had plenty of stuff closed without action.
  check the removable and washable.
Second, the slow return of head on, or go back to the top dead center, upper blade holder with pressure tanks action sequence is not coordinated.
 1) return cylinder nitrogen gas pressure is low.
check whether the nitrogen cylinder leakage and adjusted to the rated pressure 4-5MPa
 2) eccentric on bearing
III, the turret turret with cylinder pressure inconsistent action sequence
1) lack of nitrogen, nitrogen-filled to rated pressure.
