maintain:

1、 Industry Microwave equipment Generally Feed and discharge microwave suppressor microwave heating It is composed of furnace body, microwave cooling section furnace body, frame and shield, mesh belt and transmission system, microwave energy feeding system, exhaust system, circulating cooling water system, temperature control system, control system, stabilized power supply, press conveying line, feeding temporary storage line, discharging temporary storage line, etc. Metal impurities are strictly prohibited during operation . If the conveyor belt is long , It is necessary to add a deviation correction device to prevent the scraping damage of the conveyor belt during operation .

two Regularly maintain the deviation correction system and transmission system Microwave Oven Cavity, exhaust system, waterway system, temperature measurement system, power cabinet, electric control cabinet, rack assembly, etc.

three 、 Industry When microwave equipment is working, The temperature inside the furnace chamber is one hundred and fifty ℃ above, Microwave high temperature Segments can even reach one thousand ℃ Therefore, the design adopts Microwave cooling section furnace body 、 Exhaust system, circulating cooling water system, temperature control system, control system And other multiple facilities to ensure production safety. Magnetron Air cooling and water cooling are available , The transformer is also one of the two heat dissipation modes . From the use effect of our customers , The heat dissipation effect of water cooling is better than that of air cooling , In particular, the transformer is immersed in transformer oil , Isolate the impact of dust in the air . As long as the water flow is sufficient , Inlet water temperature is below 28 ℃ , The service life of the device can be greatly enhanced , Can work continuously for more than 20 hours without stopping production 。

repair:

one , when Industry When the low voltage of microwave equipment cannot be added ， It may be caused by disconnection or poor contact of the circuit breaker ， The solution is to check whether the connector of the circuit breaker is tightened ， Or replace the circuit breaker 。

two , when Industry When microwave cannot be added to microwave equipment ， The temperature switch may be damaged or the wire package of the contactor may be burnt out ， The solution is to replace the temperature switch or contactor 。

three , if Industry If the microwave device always jumps off after being turned on , At this time, there may be three situations : I The magnetron or transformer is burnt out , At this time, the magnetron or transformer needs to be replaced ； II Voltage doubling rectifier diode is broken down , This requires replacing the diode ； III Short circuit due to breakdown of high-voltage capacitor , Replace the high-voltage capacitor 。

four 、 Industry The fan of the microwave device does not work or the sound is abnormal ， Possible three-phase power supply phase loss ， Check and eliminate it ； It may also be the fan blade touching the shell ， It is necessary to repair the fan blade 。
