Rubber vulcanizing press, also known as hot press molding machine, flat vulcanizing machine, and automatic tablet press, is a kind of molding machine. The rubber vulcanizing press can be used as the basis for batching before the factory mass production. There may be some problems when using the rubber vulcanizing press. The following is a good troubleshooting method for common faults.
Here is the content list:
● What are the possible failures of the rubber vulcanizing press?
● How to solve the possible failures of the above-mentioned rubber vulcanizing press?
Fault 1: the plunger does not rise after the rubber vulcanizing machine is turned on. The reason for this phenomenon may be: the oil pump does not deliver oil, and the oil pump may rotate in the opposite direction or be damaged; the oil return valve handle is in the mold opening position; the motor is reversed.
Fault 2: abnormal noise. The reasons: there is a lot of air in the pipeline of the rubber vulcanizing press; the oil filter is blocked; the oil level in the fuel tank is too low, and the air is breathing into the pipeline; the oil pump is damaged.
Fault 3: the rubber vulcanizing press will not increase pressure or increase the pressure very slowly. The reasons for this failure are: high-pressure pump failure; the high-pressure relief valve is not closed; leakage on the pipeline; pressure gauge failure.
Fault 4: the rubber vulcanizing press cannot maintain pressure. The possible reasons are: the seat and disc of the drain valve are not tightly sealed; the valve core in the one-way valve is not tightly sealed; the leakage of the pipeline or cylinder is reduced.
Fault 5: homesick vulcanizer heating does not display. The possible cause is that the ammeter is broken; the heating tube may be damaged.
Fault 6: the tablet does not heat up. The possible reasons are as follows: the thermal resistance of the rubber vulcanizing press is damaged; the connecting wires at both ends of the thermal resistance may be broken.
1, Solution to failure one: electrical connection test or remove the oil pump for maintenance; pull the handle to the correct position; replace the live wire.
2, Solution to failure two: up and down the press several times, exhaust air; remove the rubber vulcanizing press and clean; add oil; remove and repair or replace.
3, The solution of the third fault: remove and check and repair; remove and clean the correct pressure adjustment; check out the leak and remove it; replace the pressure gauge of the rubber vulcanizing press.
4, Solution to failure four: remove, clean, grind or change; check whether the oil inlet cylinder tube of the rubber vulcanizing press is loose, and then tighten it.
5, Solution to failure five: observe the condition of the temperature controller pointer, such as turning the pointer clockwise to the end, explain that the thermal resistance wiring is open or the thermal resistance is blown.
6, The solution of fault six: check with the exchange method or observe whether the electric thermal contactor is operating when the temperature controller is operating, then connect the broken wire, and replace the temperature controller with the rubber; replace the fast melting core of rubber vulcanizing machine or connecting line.
