Rotary air shower blower speed efficiency and balance check

- Apr 24, 2018-

Air shower blower in the process of operation will be due to its impeller running in the body without friction, in the operation does not require lubrication, so you can make the exhaust gas without oil, air shower blower to a certain extent, chemical, Food and other industries are ideal for air delivery.

The air shower blower is, to a certain extent, a volume-operated blower, which changes with its pressure in the process of use. Its flow variation is very small, but its flow rate changes with the rotational speed. Therefore, the range of pressure options is very wide, and the choice of flow rate can be achieved by selecting the speed.

The blower of the air shower blower has a high rotational speed, a small gap between the rotor and the rotor, and between the rotor and the body, and thus leaks less in the process of operation, and the volumetric efficiency is higher. The structure of the blower determines that its mechanical friction loss is very small. Because only the bearing and the gear pair have mechanical contact on the material, the rotor, the casing and the gear ring have sufficient mechanical strength.

The rotor of the air shower blower is mainly checked by static and dynamic balance. The finished product runs smoothly with minimal vibration. The blowers with the above characteristics are mainly: Roots blower, side-flow fan, multi-stage centrifugal blower. Rotor: It consists of shaft, impeller, bearing, synchronous gear, coupling, bushing and so on.

The air shower blower impeller has an involute profile during the selection process and has a high volumetric utilization rate. The entire device coupling end as a positioning end uses its 3000 double-row radial spherical roller bearings. As the free end of the gear end, the 32000 type single-row short-circle cylindrical roller bearing is selected to accommodate the axial displacement of the rotor during thermal expansion.

The synchronous gear of the air shower blower is mainly composed of a hub and a ring gear in the process of operation, and is convenient for adjusting the clearance of the impeller. The body of the entire device is mainly composed of a case and left and right wall plates during the production. The left and right wall panels and the bearing seats and seals installed in the left and right wall panels can be used interchangeably. The small and medium-sized fans are equipped with a common base, and the large-sized fan only has a fan base for easy installation and debugging.
