Description

Medium-pressure long-tube air blower

Technical Field

The utility model relates to a well forced draught fan technical field especially relates to well pressure long tube forced draught blower.

Background

The common medium pressure fan is a centrifugal fan, a mechanical shell is covered outside an impeller, and an air inlet is formed in the center of the impeller. When the medium-pressure fan works, the power equipment operates to drive the impeller to rotate, and air is sucked from the air inlet. The blades of the centrifugal fan exert a power action on the gas in the rotating process, so that the pressure and the speed of the gas are improved, and the gas is discharged from the gas outlet along the blade channel under the action of the centrifugal force. During operation of the medium pressure fan, although the rotation of the impeller increases the pressure and speed of the gas, the gas has small variations, and therefore the gas is generally treated as an incompressible fluid during the design and use of the centrifugal fan. The gas treatment process of the medium pressure fan is completed in the same radial plane, so the medium pressure fan is also called a radial flow centrifugal fan.

Centrifugal fan can produce a large amount of noises when moving, and the common mode of making an uproar falls to centrifugal fan is: a silencer is arranged on an inlet and outlet pipeline of the fan, but the mode cannot reduce the outward transmission of noise from the shell; the noise elimination material is coated, the mode needs one-time investment, and the noise elimination material is often coated again when the fan is overhauled and replaced, so that new cost is generated; the single machine room of medium pressure fan sets up, and it is big to have an area of occupation of land, the big problem of investment, and equipment management personnel must still regularly get into high noise machine room moreover and inspect, maintain the fan. In addition, when the existing centrifugal fan is used, the air inlet is not provided with a filtering device, and if a user carelessly places sundries such as sponge or cotton in the vicinity of the centrifugal fan, the sundries can be sucked into the centrifugal fan, so that troubles are brought to the user, and the motor can be burned out in serious cases, so that economic loss is brought to the user. Based on the existing problems, a medium-pressure long-tube blower is provided.
