A high sealing gas supercharged centrifugal blower

Abstract

The invention relates to the field of blowers, in particular to a high-seal gas booster centrifugal blower, which includes a volute and a motor. A rotating shaft hole is arranged on the side of the volute close to the motor. The rotating shaft of the motor is inserted in the rotating shaft hole, and the rotating shaft is located at An air seal bushing is set on the outer side of the inner area of ​​the shaft hole, and an air seal seat is provided between the air seal bush and the shaft hole, and a sleeve is provided on the end surface of the air seal seat near the cavity. The gas seal pressure plate on the outside of the gas seal bushing, the gas seal seat and the gas seal pressure plate are fixedly connected with the motor seat connector through the fixing bolts, and there is an air seal in the area surrounded by the gas seal bushing, gas seal seat and gas seal pressure plate area. The invention overcomes the defect that the gas booster centrifugal blower in the prior art is prone to loose seals at the connection between the shaft and the casing, resulting in gas leakage, and can effectively prevent the problem of poor sealing between the motor shaft and the casing, effectively preventing A gas leak.

Description

technical field [0001] The invention relates to the field of blowers, in particular to a high-tight gas pressurized centrifugal blower. Background technique [0002] The gas blower is a special power equipment for transporting gas in the coke oven gas purification process. It is generally installed after the initial cooling of coke oven gas, and it is also installed at the end of the gas purification process. The gas blower is the core equipment of the coke oven gas transmission and purification system in the coking plant. Once it is shut down, it will not only affect the normal production of the coke oven and chemical production processes, but also cause the gas to be out of balance in the whole company, affecting the sintering, ironmaking and steelmaking systems normal operation, so it is very important. [0003] There are two types of gas blowers: volumetric and centrifugal. Centrifugal blowers, also known as turbine blowers, are the most commonly used blowers in coking...
