Vertical thermal power offer steam boiler will affect a large fan vibration running long vertical steam boiler fan speed operation, large mechanical wear and vibration, especially at low load unit, fan baffle throttle more, fans work in the unstable region, easily cause fan vibration. In addition, low vertical coal-fired steam boiler induced fan system automation level, can not adjust, low operating efficiency, fan vibration is relatively strong, not only equipment maintenance costs, but also poses a potential threat to the safe operation of the unit. Vertical steam boiler can be considered, Fan Vertical coal-fired steam boilers high pressure transducer, induced draft fan boiler using frequency control. To do the following: First, each exhaust fan arranged a high-voltage inverter. The inverter is connected to the high speed winding machine. Low speed winding of the motor coupled to the low-speed circuit breaker for the bypass operation when the inverter failure. Then, between the drive motor and additional disconnecting switch cabinet, electrically connected to the low-speed circuit breaker. High motor speeds, the door closing isolation knife, the low-speed circuit breaker closing prohibition. Motor bypass operation, the isolation switch off, the low-speed low speed motor control circuit breaker. Output frequency of the inverter is controlled by the speed control signal in accordance with the negative pressure 4-20mA vertical coal-fired steam boiler furnace start and stop the inverter output control signal by DCS.
Steam boiler maintenance need to pay attention to what the problem after running for some time will thermal power offer steam boiler maintenance, security detection is essential work, maintenance and safety checks should pay attention to what matters? Here to share with you: should be observed only work if the environment with working conditions, the conditions should not have long to notice the value leaders on their superiors, before a shutdown maintenance work. B before maintenance work, operations officer inform cut off water, electricity, gas source by the person listed. c repair should the tool, a variety of materials, accessories good place to prevent falling into the device, piping or inside the furnace. d into the furnace, when the smoke duct space such operations should be well ventilated, temperature is lowered to the working temperature before entering the work. E After work is completed, check whether the tools, materials, complete accessories, such as to prevent left in the furnace space inside. F After work is completed, someone delisted before leaving the job site after acceptance. The inspection results reported values g long, and do maintenance records. Steam boiler maintenance concept is a direct impact on the life of equipment, and business users is noteworthy things to do repair and maintenance, to ensure the normal operation of equipment.
Industrial boiler manufacturers how the election? Industrial boiler manufacturers how the election? There are a variety on the market, everywhere gem boiler manufacturers, boiler brands have mushroomed continue to emerge. Industrial boiler manufacturer so much, so that enterprises in the choice is very difficult when the boiler manufacturers, boiler manufacturers how to choose it? What kind of boiler brand is good? To pick boilers, boiler compared to the merits, it is necessary to look at the different boiler products. The meaning is that the pot heated on the fire water container. Stove refers to local fuel combustion. A pot boiler and furnace components. Industrial boiler manufacturers how the election? The boiler is no absolute good or bad, each boiler products will have different advantages and disadvantages, we can determine whether or not suitable for use on demand, after all, is the best fit.
