Zinc alloy die-casting oil temperature machine is widely used in the zinc alloy die-casting industry at the same time, there will also be the problem of the use of zinc alloy die-casting oil temperature machine.
Click here to learn more about the oil temperature machine.
First of all, the zinc alloy die-casting oil temperature machine is not heating the problem, the common reason why the zinc alloy die-casting oil temperature machine is not heated is the heating circuit tripping, in this case, the circuit must be carefully checked, the heating circuit trips because of the short circuit, overcurrent and other situations, can not be closed again without checking clearly, so as not to burn out the components and other greater problems.
There are also short circuits or voltage shocks that cause the overcurrent protection relay to act, and it is necessary to check the specific cause of the fault and reset the overcurrent protection deviceThen there is the heater burning, which is the simplest as long as the resistance has an infinity between some two phases.
When the control voltage is added to the contactor, the contactor does not operate or is always in a state, then it is necessary to observe the state of the contactor and pay attention to the state after powering on, so as to judge the situation of the contactor.
The common problem of zinc alloy die-casting oil temperature machine is that the heating temperature cannot rise or is unstable, the reason for this situation may be that there is a problem with the liquid level sensor or the temperature controller is damaged, and there may be some damage and the thermocouple is damaged or the contact is poor, due to the damage or poor contact of the thermocouple, the temperature is a fixed value or the temperature display change range is very high and low, resulting in the heating output control disorder.
