What is the reason of the phase error?
The industrial chiller mainly acts on the plastic processing machinery molding mold, injects frozen water into the flow channel inside the mold, cools the mold at a constant temperature through heat exchange, and maintains the temperature at a constant state to meet the needs of the production process. In this process, the mold acts as a heat exchanger.
What is the cause of the reverse phase failure of the industrial chiller?
Refrigerator reverse phase loss fault is mainly a common fault with abnormal power supply. There are two main reasons, one is the damage of the freezer protector, and the other is the lack of phase or phase sequence of the refrigerator power supply.
How to check whether the power protector is damaged?
In the case of normal power supply, close the air switch of the control box of the refrigerator, and the indicator light on the power protector of the refrigerator will be on at this time. Under normal circumstances, red means power supply, yellow means power supply is normal, and only red is on. If it is, it means that the power supply of the low-temperature freezer is missing one item or the order is incorrect. If it is confirmed that the power supply is normal, but if the indicator light of the power protector does not light up, the protector is broken. At this time, it is necessary to judge whether the phase is missing or reversed according to these reasons. You can find out the phase with less power to eliminate it and change the wrong order, or replace the power protector of the refrigerator.
Basically, the cause of the reverse phase loss fault that everyone sees is relatively simple, and it is more convenient to repair. As long as there is an electrical knowledge base, it is basically repaired.
In fact, the power supply of the refrigerator is powered by a three-phase four-wire system. In order to prevent mechanical failure or burning, it is recommended that you install a power protection device.
