Cautions

1. The microwave source equipment works under high voltage and has high requirements for the working environment, so it should be avoided in places with large humidity and dust.

2. If the microwave source equipment is operated improperly, it may be harmed by high voltage electric shock and microwave radiation. The high pressure of microwave sources can be deadly, therefore, the use of microwave source equipment operators must be strictly trained personnel, while having relevant knowledge and experience.

3. When maintaining the high-voltage power supply, the residual voltage is maintained in the device even if the power switch is turned off. If necessary, short-circuit the high-voltage capacitor.

4. Every time a microwave source is used, all safety systems must be properly in place and working properly.

5. Detection of microwave leakage must be mandatory and frequent, at 5 cm from the measurement point, and under normal operating conditions, the microwave leakage should not be greater than 5 MW /cm3. If the value exceeds the specified value, troubleshooting should be carried out according to the description in the manual.

6. The microwave source equipment must be checked and ensured that the water cooling circulation system is turned on and in normal working state before being turned on each time, otherwise it must not be turned on to avoid damage to the microwave source.

Seven. The cooling circulating water used by the microwave source should meet the requirements of the relevant water quality in GB10067.1-88, the total hardness (CaO mg equivalent) is less than 10, the inlet temperature is 5-30℃, the outlet temperature is less than 50℃, and the working pressure is 0.06 ~ 0.12MPa. The cooling water should be cleaned regularly (it is recommended to clean once every three months), if the cooling water is blocked, it will cause the magnetron to overheat, shorten the service life, and even be burned.

8. Microwave sources are vulnerable to damage under any of the conditions of overcurrent, overvoltage, overpower and poor cooling, especially the magnetron, its core component, which is very delicate and expensive. Therefore, the anode current should be controlled below the rated value in the long-term operation of the equipment to ensure the service life of the magnetron.

9. The cavity of the microwave sintering furnace must be cleaned frequently to remove all sediment, including the waveguide window; Remove the mixed metal and other foreign matter that may cause arc, and the sediment at the waveguide window, blind plate, etc., should be cleaned frequently with alcohol and kept clean. If the waveguide window is polluted, the microwave energy will be blocked and cannot enter the sintering furnace, or strong heat will be generated on the surface, and even high frequency ignition phenomenon will damage the microwave source in serious cases.

10. When sintering volatile and corrosive materials, the impact of materials on equipment and protective measures should be fully considered; Special attention should be paid to the effect of material volatilization on the waveguide window, observation window, blind plate and temperature measuring window during sintering.
