Maintenance and precautions for plate vulcanizer

The correct use and necessary maintenance of the machine and keeping the oil clean can effectively prevent the failure of the oil pump and the machine, prolong the service life of the various components of the machine, and improve the production efficiency of the machine, so as to create greater economic benefits.

1. Precautions for the use of plate vulcanizer
1) The mold should be placed in the middle of the hot plate as much as possible.
2) Before each shift of production, all parts of the machine, such as pressure gauge, electronic control buttons, hydraulic parts, etc., should be checked, if the sound is abnormal, it should be stopped immediately for inspection, and the fault can be eliminated before continuing to use.
3) The fixing bolts of the upper hot plate and the upper beam should be checked frequently to see if there is any looseness. If it is found to be loose, tighten it immediately to prevent the screw from being damaged by pressure during vulcanization.

2. Maintenance of plate vulcanizer machine
1) The working oil should be kept clean and there should be no stolen goods. After 1-4 months of machine operation, the working oil should be pumped out and filtered and reused, and the oil should be replaced twice a year, and the inside of the oil tank should be cleaned at the same time.
2) When the machine is out of use for a long time, all the working oil should be withdrawn, the oil tank should be cleaned, and the contact surface of each machine part should be added with anti-rust oil to prevent rust.
3) The fastening bolts, screws and nuts of each part of the machine should be checked regularly to prevent loosening and causing undue damage to the machine.
4) After the cylinder sealing ring is used for a period of time, the sealing performance will gradually decrease, and the oil leakage will become more, so it must be checked or replaced frequently.
5) There is a filter at the bottom of the oil tank, often filter the hydraulic oil at the bottom of the tank to keep the oil clean, otherwise the impurities in the hydraulic oil will jam the hydraulic components and even damage the components to cause greater losses. The surface of the filter is often attached to impurities, which must be cleaned, if not cleaned for a long time, it will be unusable due to the blockage of the filter.
6) Check the motor regularly, and replace the grease in the bearing, if the motor has been damaged, it should be replaced in time.

7) Regularly check whether the connection of the electrical components is firm and reliable, the electric control cabinet should be kept clean, the contactor contacts must be replaced if they are worn, the contacts cannot be lubricated with lubricating oil, and if there are copper particles or black spots on the contacts, they must be polished with fine frustration or abrasive cloth.

3. Common faults and troubleshooting methods
of plate vulcanizer The common fault of 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.
