Oven is a new type of oven equipment on the market today. Its advent has brought new sales storms to the oven industry. Many people can't help but be attracted by its perfect design and superior performance. The following is a description of the knowledge of the hot air circulation oven and the analysis of common faults.

The temperature control of the oven cabinet popular in the market generally adopts GCD-23A intelligent computer temperature control and PLC automatic control system. When the temperature reaches the set value, the temperature controller outputs the PID control signal PLC, and the PLC outputs the control signal to the time relay KT. In order to start the insulation timer, at the same time, close the inlet and exhaust disc valves.

The common fault of the oven is mainly the closed loop oven air switch. According to the operating instructions of the oven, the heating temperature is set to 250 °C, the over temperature alarm temperature is 260 °C, and the heat preservation time is 1 h, then the automatic running program is started, the circulating fan and the inlet fan of the oven are started. The indicators such as the disc valve and heating are illuminated in sequence, indicating that the program is operating normally. After heating for 2.5h, the temperature still does not reach the set value. If the heating time is too long, the heated glass container will be brittle and the bad bottle rate will increase. Then judge whether there is a fault in the circulating fan, causing the hot air circulating air to be in poor circulation, and the hot and humid air cannot be discharged normally. Secondly, from the fault phenomenon and the circuit principle of the oven, the oven can be heated, indicating that the output signal of the GCD-23A intelligent computer temperature controller is normal, and the PLC input and output signals are also normal. As a new product of the oven's zui, the purification hot air circulation oven has taken on a lot of external pressures and doubts, but this does not affect its superior performance. As long as you master the relevant knowledge, coupled with the continuous improvement of its products, I believe it. The role played will be greater and greater.
