Our advanced management thinking and technology, reliable quality and selfless work enthusiasm are fully reflected in the various indicators of the Dust Removal Centrifugal Fan, Wall Axial Fan, Subway Tunnel Fan. With reasonable prices and excellent services, we have established long-term cooperative relations with many companies. Years of carving, we still focus on the industry, this is precipitation, this is the persistence of excellence. Our factory has always emphasized on technological innovation and research development. We have a mature management, quality, technology, warehousing, and delivery system.

When the fan starts up, the water in the dust collector boils violently and interacts with the fan, which will produce a large amplitude. The vibration will inevitably cause strong noise. In addition, the fan belongs to the centrifugal fan, which makes a lot of noise when it is running. The noise pollution caused by boiler fans seriously affects the rest of the residents living around it, which is harmful to their health. Therefore, it is necessary to take comprehensive noise reduction measures. Boiler fan manufacturers can appropriately increase auxiliary dust reduction measures to solve the problem of excessive dust. The air outlet pipe of the fan is connected to the wet dust collector through a long metal pipe. The dust remover removes the large particles of dust before entering the dust reduction and sound insulation room. The technical measures of combining expansion pipe and expansion chamber are adopted in the dust reduction and sound insulation room, which can reduce the gas flow rate, make the small particles of dust fall naturally with the condensation of water vapor in the flue gas, and at the same time play a role of resistance and noise elimination. When the gas with low velocity enters the noise reduction room and expands further.

After that, the smoke is discharged into the atmosphere through the expansion pipe at the top of the chimney. The drum and induced draft fans of the boiler can be centrally arranged in the same sound insulation fan room. The blower sucks air into the room and takes away the heat emitted by the drum, induced draft fan, and smoke pipe. The cold air supplied in the room enters the room through the air inlet muffler. The exhaust pipe of the boiler is equipped with a muffler. Generally, small-hole mufflers or multi-layer orifice plate throttling depressurization and small-hole injection composite mufflers are used. In addition, low-speed fans can be used to increase the induced draft fan impeller and reduce the fan speed. The pressure coefficient of the fan remains unchanged and the fan operates normally to reduce the noise. The herringbone cooling flue is also used to increase the distance between the induced draft fan and the residential building, to reduce the impact on the residents during the operation of the boiler fan. 4. There are several reasons for oil leakage of the bearing box: unreasonable design of felt ring seal; unreasonable design of seal chamber structure
