Product Description
According to the blade angle, the fan wheel of centrifugal fan can be divided into forward inclined fan wheel, radial fan wheel and backward inclined fan wheel; According to the blade angle of the impeller, the centrifugal impeller can be divided into three types: forward inclined impeller, radial impeller and backward inclined impeller; According to the impeller structure, the impeller can be divided into two types: multi wing impeller and split impeller; According to th...
product presentation
The main function of the nozzle group in the steam turbine is to make the steam flow on the blades of the rotor wall through the guide of the nozzle group.
The nozzle group usually refers to the first stage nozzle of the steam turbine. The first stage nozzle is divided into several groups, and each group is controlled by a regulating steam valve.
Fixing method of nozzle: the first stage nozzle is different from other stage nozzles, which can directly weld the nozzle gr...
Centrifugal compressor (blower) blade (wheel)
Centrifugal compressor (blower) blade (wheel)
A centrifugal compressor is a vane rotary compressor (i.e., a turbine compressor). In a centrifugal compressor, the centrifugal force given to the gas by the high-speed rotating impeller and the diffusion effect given to the gas in the diffusion channel increase the gas pressure.
Common materials of impellers include: cast iron, bronze, stainless steel, manganese bronze, Monel alloy, aluminum alloy,...

effect
The absolute velocity C2 at the impeller outlet of centrifugal compressor is generally 200-300m/s. The flow velocity of the impeller of the high energy head can reach more than 500m/s. This part of kinetic energy accounts for a considerable proportion of the total energy head of the gas supplied by the impeller. For example, the radial straight blade type impeller accounts for 50%, and the pump type fire compressor type impeller also accounts for 25% – 40% Therefore, this ki...
