Composite line shape and driving method of clean room centrifugal blower

- Sep 15, 2018-

The impeller of the clean room centrifugal blower mainly adopts its special composite line shape, which can reduce the internal leakage to a certain extent and effectively improve the volumetric efficiency. Easy to adjust: the inlet butterfly valve regulates the flow and the outlet butterfly valve regulates the pressure.

The driving method of the centrifugal blower in the clean room is usually a two-pole asynchronous electric vehicle when it is used, and a four-pole motor can also be used to some extent. Different voltage motors can be used depending on the customer's power grid. Sealing: Each stage of the impeller has a labyrinth seal in addition to the inlet ring, and between the stages and the casing to prevent gas leakage.

The clean room centrifugal blower exhaust bearing housing has two structures, air-cooled and water-cooled. Due to the progressive compression of the impeller, the temperature of the exhaust casing is much higher than that of the intake casing. There are air-cooled or water-cooled devices in the exhaust housing to extend the service life of the bearings.

The clean room centrifugal blower fan accessory is equipped with a temperature control box, which is connected to the bearing through the PT100 resistor. When the bearing temperature exceeds the set temperature, the temperature control box will automatically alarm. There are three kinds of coupling transmission, belt transmission and speed increase box transmission. Different transmission methods are used depending on the equipment and process.
