Sewage Backwash Multistage Centrifugal Blower with aluminum impeller , 90m³/min Inlet Pressure
Sewage Backwash Multistage Centrifugal Blower, aluminum impeller, pressure 80KPA
D series multi-stage centrifugal blower can be used for conveying air, coal gas and chemical gas, it is featured of lower noise, small vibration, high
efficiency, smooth running, easy installation and maintenance.
Working principle
During the rotation of impeller, due to the effect of rotating centrifugal force and working round diffuser flow, the speed of the
gas is increased, and then convert the velocity energy into pressure energy. Multi-stage centrifugal blower has several groups of impellers on its
main shaft, air is compressed by the multiple groups of impeller gradually.

Main Characteristics
1,Low noise: there is no mechanical friction during the air blowing operation, and reasonable blade profile is adopted to minimize the noise.
2,Small vibration: the optimized impeller reduces the axial force to the minimum so that the whole machine can run smoothly.
3,Non-mechanical friction machinery: no gear speed-up is required. The blower rotor is supported by two bearings at the front and rear. During operation, there is no mechanical friction between any parts except the bearings, so noise caused by mechanical friction is avoided, thus ensuring the longest service life of the blower host.
4,Convenient adjustment of airflow: the adjustment range of the blower's airflow is 50%~100%, which is adjusted by operating the butterfly valve at the inlet.
5,Oil-free machinery: no oil and gas will be generated during the pressurization process of the blower, so as to ensure that the aerator will not be corroded, and improve the service life of the aeration system.
6,Water cooling is adopted for the rear bearing, which extend sits service life.
7,Advanced technology adopted for the rotor for achieving with high strength and long service life.
Features
1. low noise level. It is machined with advanced CNC machining centers, operating smoothly with low vibration, producing low noise level.
2. good treatment in sealing, no medium leakage from the blower casing.
3. energy saving and in high quality, long service life.
4. capacity is easy to be adjusted. When the pressure is set, the capacity can be larger or smaller to meet the demands of different working conditions.
5. bearing is lubricated by lubrication oil, not grease, which ensures long service life.
6. impeller is of reliable performance by adopting aluminum materials and strict balancing test.
