What to do if the temperature of the water mold heater is unstable

2023-04-14 17:53

Water type mold temperature machines are used in industries such as chemical, rubber, composite materials, and die-casting. During use, users may encounter unstable temperature control or temperature instability while operating the equipment, which affects the quality and progress of the main equipment's products. The unstable temperature of the water mold heater is mainly due to the air and water in the pipeline not being discharged, which can cause significant pressure fluctuations in the system.

During the debugging process, the water mold temperature machine needs to undergo the process of liquid discharge and exhaust. Determine based on the total pipe diameter and the amount of heat transfer oil. When starting, allow the oil pump to cycle and then start heating. The temperature should not rise too fast. Generally set at 80 ℃, it is necessary to constantly observe the pressure gauge of the equipment during heating. If there are no fluctuations, you can move up step by step. When reaching 100 ℃, special attention should be paid to pressure fluctuations. It must be stable in order to increase pressure time and time again. This is because water begins to evaporate in large quantities at 100 ℃. If the heat transfer oil contains a large amount of water, and the temperature is too high, the heat transfer oil will instantly expand and flow out of the fuel tank.

The temperature may fluctuate frequently and cannot reach a constant temperature. In this case, the temperature controller may malfunction and can be eliminated by replacing it with a new one. In addition, temperature probes are installed at the inlet and outlet of the water mold temperature machine. If the temperature probe malfunctions, it is easy to cause inaccurate temperature control. For example, if the temperature control probe at the oil outlet of the water mold temperature machine malfunctions and displays the temperature of the low-temperature drying oil inlet, it is easy to cause abnormal heating. In general, the temperature of the return port is about 5 ℃ lower than the temperature of the outlet port, and the temperature controller adjusts the contact switch of the heater based on the temperature of the outlet port.
