Equipment usage precautions

1. Microwave source equipment operates under high voltage and has stringent requirements for the working environment; it should avoid use in areas with high humidity and dust.

2. If microwave source equipment is improperly operated, there is a risk of electric shock from high voltage and exposure to microwave radiation; the high voltage of the microwave source can be fatal, so operators must be trained personnel who have received rigorous professional training and possess relevant knowledge and experience. 3. When maintaining the high-voltage power supply section, residual voltage may remain in the equipment even if the power switch is turned off; if necessary, the high-voltage capacitor should be short-circuited to discharge. 4. Before each use of the microwave source, all safety systems must be correctly in place and functioning properly. 5. Microwave leakage must be regularly and compulsorily checked; at a distance of 5 cm from the measuring point, and under normal operating conditions, the microwave leakage should not exceed 5 mW/cm3. If the specified value is exceeded, troubleshooting should be performed according to the instructions. 6. Before each start-up of the microwave source, it is essential to check and ensure that the water-cooling circulation system is activated and operating normally; otherwise, the equipment must not be started to prevent damage to the microwave source. 7. The cooling circulating water used by the microwave source should meet the water quality requirements specified in GB10067.1-88, with total hardness (CaO mg equivalent) less than 10, inlet water temperature between 5-30°C, outlet water temperature below 50°C, and working pressure between 0.06 to 0.12 MPa. The cooling waterways should be cleaned periodically (recommended every three months); if the cooling waterways are blocked, it will cause overheating of the magnetron, shorten its lifespan, or even burn it out. 8. The microwave source is easily damaged when operating under overcurrent, overvoltage, excessive power, or poor cooling conditions; especially its core component, the magnetron, is very delicate and expensive. Therefore, during long-term operation, the anode current should be kept below the rated value to ensure the lifespan of the magnetron. 9. The interior of the microwave sintering furnace must be frequently cleaned to remove all deposits, including those on the waveguide window; any mixed metals and other foreign objects that could cause arcing should be removed. Deposits on the waveguide window, blind plates, etc., should be frequently cleaned with alcohol and kept clean. If the waveguide window is contaminated, it will block the microwave energy from entering the sintering furnace or generate intense heat on its surface, leading to high-frequency arcing; in severe cases, it can damage the microwave source. 10. When sintering materials with volatiles and corrosive properties, the impact of these materials on the equipment and protective measures must be fully considered; particular attention should be paid to the effects of material volatilization on the waveguide window, observation window, blind plates, and temperature measurement windows during the sintering process.
