| Housing construction: | | According to different models, the air inlet, outlet and intermediate spacer groups are all made of cast iron or cast aluminum The adjustable levels of blowers corresponding to different pressure requirements are small 10 and large 7 The air inlet, outlet and each intermediate partition group are concavoconvex connected and then clamped by steel bolts The general standard of air inlet and outlet is the connection of vertical upward devices, but different inlet and outlet directions can be selected according to actual needs. The sealing of each stage is achieved through labyrinth ring sealing system. At the same time, in order to meet the needs of some applications, a specific cover of the internal part of the main body is possible. |

| Rotary axis: | The rotary shaft is composed of a steel rod and some spacers. Moreover, the impeller bolt is locked with the shaft.
The impeller is made of cast aluminum or riveted. Each impeller is statically balanced. As for the rotary shaft, it is dynamically balanced to ensure that the amplitude is less than 4.5 mm/s under operating conditions.
In order to better meet different needs, we provide different types of impellers, including radial and curved ones. |

Bearing pedestal:
| The bearing is placed on the casting bearing pedestal.
The bearing pedestal is safely fixed at the inlet and outlet, which makes daily maintenance very easy without removing other parts. The bearing is the only one of the rotating shaft and fixed plate of the machine
A connection point. According to different application needs, graphitized belts or four carbon rings can be used to ensure the sealing of bearings. Greatly reduce leakage through carbon ring sealing
Situation. There may be a pressurized gas seal between the carbon rings.
According to different models, the following two types of bearing housings can be used: |
