What should I pay attention to before and after using the mold temperature machine?
announcer：
In industrial production temperature control equipment, the use of mold temperature machine is very common. It can be seen in the production of zinc alloy die casting, magnesium alloy die casting, rubber and plastic extrusion, and injection molding products. In addition to the advantages of relatively simple and convenient operation methods, most of the units are automatically operated. After only using the operation and setting the temperature, the operation method personnel do not need to re-unit, if the unit has a malfunction, there will be immediate Alarm reminder. But in addition to the old users who have already used machinery and equipment, many customers are also exposed to this equipment at the beginning. They are very concerned about how to correctly apply the mold temperature machine, and what is the correct operation process?
1. Inspection before operation of mold temperature machine
Check whether the surrounding area is clean and free of debris, check whether the switching power supply, electric heater, control board, barometer, pump, etc. are all normal; whether the valve of the water cooling pipe has been opened, and whether the water cooling supply is normal;
Check whether the oil level of the expansion tank is correct, whether the liquid level sensor, etc. are normal;
Connect to the switching power supply of the control cabinet, check whether the voltage is normal, and check whether the indicator lights and display instruments are normal.
2. Operation method of machine equipment
Operate the heat transfer oil circulation pump, after starting the pump, all normal circulation will stabilize the pressure within 0.5 hours;
Press the heating operation button and observe whether the heating is normal;
Be sure to pay attention to the condition of the barometer during the initial operation.
3. Operation method of machine equipment shutdown
All normal shutdown: gradually reduce the temperature and stop heating. When the temperature of the heat transfer oil drops below 70°C, stop the operation of the heat transfer oil circulation pump; turn off the main switching power supply and make handover statistics.
Emergency shutdown: If the emergency shutdown occurs due to an emergency, the heating tube should be quickly turned off to facilitate the natural cooling of the thermal oil and avoid overheating.
4. FAQ
During the inspection, pay attention to check whether there is leakage around the mold temperature machine. The surrounding should be equipped with sufficient oil and electrical fire fighting equipment, and it is forbidden to use water as a fire extinguishing agent.
