Troubleshooting method for general faults of plate vulcanizer

A common failure of the plate vulcanizer is the loss of pressure in the closed mold, when this happens, first check whether the sealing ring is damaged, and then check whether there is oil leakage at the connections at both ends of the inlet pipe. If this does not happen, the outlet check valve of the oil pump should be checked. Repairs should be made with pressure relief while lowering the plunger to the lowest position.

1. The platform is blocked by the lifting
Reason: the guide clearance is incorrect
Elimination method: adjust the guide clearance

2. The oil pump has abnormal noise
Reason: The oil in the oil tank is insufficient, and the oil pump is emptied; Blockage of suction pipe filter; Damaged couplings; The oil pump is damaged.
Elimination method: add oil, remove and clean, remove for repair or replacement, remove for repair or replacement.

3. Unable to boost pressure
Reason: The valve core of the high-pressure relief valve is not in the normal position, and the oil pump is damaged
Elimination method: dismantle for repair or replacement, repair or replacement

4. The mold closing speed is slow or cannot be closed
Reason: The oil in the tank is insufficient; The suction port is blocked, the oil pump is damaged, and the valve core of the relief valve does not reset
Elimination method: add oil, clean the oil filter, repair or replace the oil pump, clean and remove foreign matter

5. Poor pressure holding performance or unable
to maintain pressure Causes: The oil is dirty, the pressure holding valve is leaking, the pipe joint is leaking, and the hydraulic cylinder sealing ring is leaking   

Elimination method: filter or replace the oil, grind the valve core and seat cone, Repair or replace damaged parts, compress flanges or replace seals
