The precautions for using an electric heating pure steam generator mainly include three aspects: operating standards, safety maintenance, and daily management. The following are specific points:
1、 Preparation before operation
1. Equipment inspection: Before starting, it is necessary to check whether the power circuit, water level gauge, safety valve, pressure gauge, etc. are normal to ensure that there is no water leakage or electric leakage.
2. Water quality requirements: Softened water or purified water must be used to avoid scaling caused by groundwater or well water, which may affect heating efficiency.
3. Environmental safety: Flammable and explosive materials are prohibited from being stored around the equipment, good ventilation should be maintained, and reliable grounding should be ensured.
2、 Precautions during operation
1. Parameter monitoring: closely observe pressure, temperature, and water level, and prohibit overpressure operation (if it exceeds 0.4MPa, stop immediately).
2. Exhaust operation: After the first start-up or long-term shutdown, the exhaust valve needs to be opened and closed multiple times to exhaust the air inside the furnace to avoid steam carrying water.
3. Prohibition of leaving the post: During operation, operators are not allowed to leave without authorization, and must remain awake during night shifts.
3、 Shutdown and maintenance
1. Standardized shutdown: After turning off the power, the remaining water should be drained, the water tank and furnace chamber should be cleaned to prevent the accumulation of scale.
2. Regular sewage discharge: The furnace chamber needs to be drained once a day, the safety valve function needs to be tested weekly, and the water tank needs to be cleaned monthly.
3. Component maintenance: Clean the heating tube every 2-3 months and regularly polish the water level electrode probe to ensure sensitivity.
4、 Special scenario handling
1. First use: The water pump air needs to be emptied first, and the steam valve should be half opened to control the steam purity.
2. Winter antifreeze: When not in use, drain the stored water and take insulation measures for the water pump.
3. Fault handling: Stop the machine immediately in case of any abnormalities, contact professional personnel for maintenance, and prohibit self disassembly and modification of the circuit.
The above measures can ensure the safe and efficient operation of the equipment and extend its service life. If you need further information on troubleshooting or maintenance details, you can refer to the relevant guidelines.
