The use of machinery and equipment has risks, and the use of steam generators is no exception. Therefore, we must take good maintenance and preventive measures to ensure the use and characteristics of machinery and equipment, and effectively improve the service life.
1. Prevent the steam generator from entering too much steam: restart when the water heater valve is set, and the steam turbine unit side should allocate funds to lock the machinery and equipment, and fasten the check door of the exhaust pipe of the high-pressure cylinder to prevent the door from closing too loosely and causing the heat treatment furnace. Too much steam.
2. Prevention of over-temperature and over-pressure: the adjustment of pilot ignition should be improved within the adjustment period of the steam boiler valve to prevent over-pressure safety accidents; when the bypass valve of the main power switch and the fuel dispenser are switched on and off, the pressure should be stable and the bypass valve should be adjusted. The standard regulations are: the small opening degree of the high side should ensure that the re-electric water heater is hot, and the small opening degree of the low side should ensure that the re-electric water heater is not overpressured; in order to prevent accidental overpressure of the natural gas gas steam boiler during the whole process of adjusting the gate valve, the PCV ( That is, the induction coil releases the valve) should ensure that the hand-pull power main switch is reliable.
3. Prevent uneven bearing capacity of the seismic support and hanger: During the whole process of heating the DC transformer, send staff to check the expansion and the bearing capacity of the seismic support and hanger. Obvious abnormalities (such as large tremors) should be adjusted immediately.
4. Prevent steam leakage: improve on-site inspection, pay attention to check the tightness of the welding, manhole, hand hole and flange of the steam generator.
5. On-site difficult problems: the lighting equipment should be sufficient to adjust the location, and the ground should be smooth to prevent the steam from spraying out after the gate valve posture and causing disability. It is not important for workers to stay by the side; there is a reliable, convenient and fast communication system to keep the rotary kiln and the main control. The staff should cooperate with each other and follow the guidance.
Because the risk of the steam generator is very serious, the staff should pay extra attention and observation during the operation process to ensure the regular use of the machinery and equipment, and do a good job of checking the machinery and equipment on time. Immediately solve the problem to avoid harming the utilization rate of machinery and equipment.
