The side channel blower model is not known to many people. The numbers and letters represent the type and application range of the side channel blower, as well as the key parameters such as wind pressure and air volume. Then we will analyze and explain the data and charts for everyone. The meaning of the side channel blower model:
The side channel blower model classification can be generally divided into two types: centrifugal side channel blower and axial side channel blower. Then we analyze what the parameters of the two side channel blower models represent:
 
1, centrifugal side channel blower
 
The meaning of the centrifugal side channel blower model: consists of the basic model and the supplementary model. If the basic models of the side channel blowers are the same and the uses are different, for the sake of convenience, add the symbols "G" or "Y" before the basic model. “G” means the blower (blower) “Y” means the induced draft side channel blower. The supplemental model consists of two digits. The first digit indicates the side channel blower inlet type, expressed as “0”, “1”, “2”, where “0” stands for double suction side channel blower; “1” stands for single suction side channel blower; “2” stands for two-stage series side channel blower. The second digit represents the design serial number. The complete representation of the side channel blower model includes: name, model, machine number, transmission mode, direction of rotation, exit position, etc. For example: W9-26No16D
 
The first position represents the use of the side channel blower W high temperature F anti-corrosion B explosion-proof ...
 
The second position represents the pressure characteristics of the side channel blower. 9 High pressure 8 High pressure 6 Medium pressure 5 Medium pressure 4 Low pressure 3 Low pressure
 
Third position connection symbol
 
The fourth position represents the characteristic ratio of the pressure and the air volume of the side channel blower. 72 Large air volume 68 The air volume 26 Low air volume 19 Small air volume 12 Small air volume Fifth position Mathematical symbol
 
The sixth position represents the side channel blower impeller diameter 16 impeller diameter 1.6 m 12 impeller diameter 1.2 m 10 impeller diameter 1.0 m
 
4-72 No5A
 
side channel blower model: 4-72
 
4 represents the pressure coefficient
 
72 represents the air volume coefficient
 
No is the meaning of the number
 
5 represents the impeller diameter (500mm)
 
A transmission mode
 
The motor is directly connected to the side channel blower
 
Centrifugal side channel blower model
 
It consists of a basic model and a supplementary model.
 
2, axial side channel blower
 
The following classifications are made according to the characteristics of axial side channel blowers:
 
Classified by material: steel side channel blower, fiberglass side channel blower, plastic side channel blower, PP side channel blower, PVC side channel blower, magnesium alloy side channel blower, aluminum side channel blower, stainless steel side channel blower, etc.
 
Classified by use: explosion-proof side channel blower, anti-corrosion side channel blower, explosion-proof anti-corrosion, special axial side channel blower side channel blower and other types.
 
Classified according to the requirements of use: pipeline type, wall type, post type, fixed type, rainproof and dustproof type, mobile type, motor external type, etc.
 
According to the installation method, it can be divided into: belt transmission type and motor direct connection type.

blower
It can be used for ventilation, ventilation or heat dissipation in metallurgy, chemical industry, light industry, food, medical equipment, mechanical equipment and civil buildings. If the casing is removed, it can also be used as a free side channel blower or a longer exhaust. The pipes are installed in series at intervals to increase the wind pressure in the pipes.
 
Axial side channel blower model 200FZY4-D:200 is the model of the side channel blower (generally refers to the diameter of the blade), F-side channel blower in YZFZ, Z-axis flow side channel blower, Y-cylinder. (generally the speed of the motor) is also the 4-pole motor we often say.
 
3, rotary side channel blower
 
The rotor chamber is rotated to change the volume of the chamber to operate. Common varieties are Roots blowers and rotary compressors. Design the rotor to rotate eccentrically in the cylinder, oil lubrication, low speed, air volume range: 0.31 cubic meters per minute to 5.41 cubic meters per minute, pressure range: 9.8 kPa to 49 kPa variable displacement compressed low noise blower It is a rotary side channel blower
 
Rotary side channel blower use
 
1. Water treatment blast aeration
 
2, the hospital's sewage aeration and aeration
 
3. Vacuum feeding in the printing industry
 
4. Stirring and aeration of domestic sewage and industrial wastewater
 
5, plastic welding, air supply
 
6, burner spray, glass industry
 
7. Aquaculture
 
8. Other equipment that requires a gas source.

The meaning of the side channel blower model
 
side channel blower type 4-72-5/A 4-72 refers to a type of side channel blower of low pressure and large air volume side channel blower series. 5A represents a type of side channel blower whose side channel blower diameter is 500 mm and the motor is directly connected to the impeller. The air volume is generally 3864-15455M^/ H. The wind pressure is generally 502-3187PA. It is equipped with two motor powers of 2.2 kW and 15 kW. 4-72 is a series of side channel blowers, generally used for blasting, 5A is a model, that is to say, the impeller is 500MM
 
What is the meaning of high pressure centrifugal side channel blower model TG-10-IIIN011D?
 
From the side channel blower numbering rules: T stands for ventilator; G stands for high pressure or boiler; 10 stands for specific speed; III stands for model derived from a side channel blower model; 11 stands for impeller diameter of 1100mm; D stands for transmission type, expressed as joint Shaft drive.
 
example:
 
What are the numbers of the centrifugal side channel blower model 9-19-7.3?
 
Simply put: the first group number 9 is the full pressure coefficient of the side channel blower. It is obtained by multiplying the total pressure coefficient by 10 and then taking a single digit. Example: 0.586*10=5.86, take “6”. The second set of numbers 19 is the ratio of the number of revolutions, and the number of revolutions is determined by a set of formulas. The second group 7.3 indicates the machine number, which refers to the outermost end of one blade in the impeller of the side channel blower, and the outer end of the other blade opposite the center is equal to 730 mm. Usually, the number of revolutions is greater than or equal to 60 for low pressure side channel blowers; 30-60 for medium pressure side channel blowers; and 15-30 for high pressure side channel blowers.

What is the meaning of side channel blower model 9-19 NO:16D?
 
9-pressure coefficient 19-air volume coefficient No-number 16-impeller diameter (this impeller diameter is 16x1.14=18.24 decimeter) D--coupling drive
 
9-19-16.5D What does this side channel blower model mean?
 
The first position 9 represents the pressure coefficient. The second position 19 represents the flow coefficient. The third position No means the number. The fourth position 16.5 means that the side channel blower impeller diameter is 1650mm. The fifth position D means the side channel blower is D-type transmission (single cantilever support) )
 
The correct way to write is that 9-19No16.5D induced draft side channel blower 9-19-100 bearing model is much better? 9-19NO9.8D, 9-26-710 bearings are much better? Seeking heroes pointing 9-19-10D 9-19-7.1D And 8D 9D is 3616 D is the transmission mode coupling

side channel blower model: The front number indicates the side channel blower type, impeller diameter, which is the abbreviation of side channel blower impeller diameter / 100mm.
 
What does A, B, C, and D follow behind the side channel blower model?
 
A, B, C, D, E, F are the transmission mode of the motor and side channel blower.
 
A: Direct connection, the motor shaft is the side channel blower shaft
 
B: Indirect connection, such as a V-belt, the pulley is between the two bearings
 
C: also indirect connection, using a V-belt, the pulley is cantilevered
 
D: elastic coupling is connected, the side channel blower is in cantilever shape
 
E; pulley connection, but the side channel blower is between the two bearings, relatively stable
 
F: Coupling connection, side channel blower between two bearings, for large side channel blower
 
For example, 15A is the side channel blower impeller of 1500mm, and the motor and side channel blower are directly connected.
