9-19 type medium pressure centrifugal fan

The medium pressure range of the fan is 3000-6000PA.

Structure of medium and high pressure centrifugal fan

№4 ~ 6.3 are mainly composed of impeller, casing, air inlet, bracket, etc .; №7.1 ~ 16 are mainly composed of impeller, casing, air inlet, transmission group, etc.

Impeller—9-19 fan blades have 12 blades, and 9-26 fan blades have 16 blades, all of which are forward curved. The maximum peripheral linear speed of the outer edge of the impeller diffuser exceeds 140m / s. After the impeller is formed, it is subjected to static and dynamic balance correction and overspeed operation experiments, so the operation is stable and reliable.

Chassis—Welded into a volute-shaped whole with ordinary steel plates.

Air inlet—made into a convergent and streamlined overall structure, and bolted to the front cover.

Transmission group-composed of main shaft, bearing box, coupling and so on. The main shaft is made of high-quality steel. The overall structure of the bearing box adopts rolling bearings and is lubricated with bearing grease.

Installation and use of medium and high pressure centrifugal fans

Before installation: All parts of the fan should be thoroughly inspected, whether the parts are complete, whether the impeller and the housing are in the same direction of rotation, whether the parts are tightly connected, whether the main parts such as the impeller, main shaft, and bearings are damaged, and whether the transmission unit is flexible.

During installation: Pay attention to check the casing. There should be no tools or sundries falling or remaining in the casing. In order to prevent rust and reduce disassembly difficulties on some joint surfaces, a layer of grease or mechanical oil should be applied. The joint surface between the fan and the foundation and the joint interface between the fan and the air inlet and outlet pipes are carefully adjusted to fit naturally. Do not force the connection. Do not add the weight of the pipe to the fan components, and pay attention to ensure the horizontal position of the fan.
