What does the model 9 28 18d mean by sintering fan in our factory?

This is a wind turbine, 9 – pressure coefficient.

28 - specific speed.

18-impeller diameter 1800mm

d——Coupling transmission.

This is a high-pressure centrifugal fan.

9 represents the pressure coefficient, 26 specific speed, 14 is the impeller size 1400mm, and d is the connection form of the impeller and the motor (single cantilever support).

The model of each factory is different, the meaning of the representative is almost the same, I here take the FRP anti-corrosion centrifugal fan of Foshan Zhengzhou environmental protection ventilation equipment **** as an example: GF4-72-8C 30KW GF represents round mouth anti-corrosion (F represents square mouth anti-corrosion) 4 represents the pressure coefficient (3-4 low pressure, 5-6 medium pressure, 7-8 high pressure) 72 represents the flow coefficient (12 small air volume, 19 small air volume, 26 low air volume, 68 medium air volume, 72 large air volume), 8 represents the impeller diameter (8 =diameter meters), C represents the linkage mode (A type motor direct connection, C belt transmission) 30KW represents the motor power.

The first position 9 represents the pressure coefficient.

The second position, 19, represents the flow coefficient.

The third position no represents the meaning of the number sign.

The fourth position represents the diameter of the fan impeller is 1650mm, and the fifth position d represents that the fan is D-type transmission (single cantilever support), and the correct way to write it is to be.

1, 9 represents the pressure coefficient; 19 represents the flow coefficient ; It means that the diameter of the impeller of this fan is 1650mm

D represents that the fan is D-type drive (single cantilever support).

2. Fan is the customary abbreviation of gas compression and gas conveying machinery in China, and the fan commonly referred to includes: ventilator, blower, and wind turbine. Gas compression and gas conveying machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy, and transports gas out.

The main structural components of the fan are impeller, casing, air inlet, bracket, motor, pulley, coupling, silencer, transmission parts (bearings), etc.

For example, Y5-47-6C y is the mother of the first pinyin character of the Chinese character 'citation', guiding the fan;

Another example is the g for the blower; C6-48-10C C refers to the dust removal fan.

The main structural components of the fan: impeller, casing, air inlet, bracket, motor, pulley, coupling, silencer, transmission parts (bearings), etc.

The unpowered ventilator uses the natural wind force and the air heat convection caused by the temperature difference between indoor and outdoor to push the turbine to rotate, so as to use centrifugal force and negative pressure effect to discharge the stale hot air in the room.

The fan is related to the energy consumption of the system and is a very critical part of building energy saving. According to the National Air Conditioning Equipment Quality Supervision and Inspection Center, many fans have problems under rated working conditions, so it is necessary to produce and manufacture fans in strict accordance with product standards.

HTF (XPZ, PYHL) is the same series of fire axial fans, HTFC (DTP) series is a unified cabinet centrifugal fan, GXF (SJG) series is a mixed-flow fan, and so on at the beginning of the number is the national standard fan expression, you can refer to the fan manual, mainly look at the parameters and use, the model indicates that many manufacturers are different now.

The point, remember to powder me i

HTF - Mixed Flow Fan.

GXF - Public Fire Protection.

4-79, 4-wind pressure coefficient, 79-air volume coefficient.

These are available in the fan brochure and in the fan product brochure.

HTF is a common term for fire fans, (XPZ, PYHL) These are other names.

Are the wind turbines you are talking about?

It's just a code name, which means you don't have to bother with it.

9- Pressure coefficient.

19 - air volume coefficient.

Number. 16-impeller diameter (the impeller diameter is decimeter) d--coupling transmission.

To make a supplement, this series of fans is a high-pressure fan.
