the impeller designed according to the regeneration theory accelerates the pressurization in the air duct, and the unique one-sided and single-stage impeller rotates to produce high-pressure air flow
The impeller consists of 30 to 50 blades to form a plurality of air chambers
When air enters these chambers, it is accelerated in both axial and radial directions
Driven by the rotating impeller, the air enters the outside of the annular chamber and the next air chamber
Such a cycle forms a vortex or like a stretched spring
The speed energy is continuously increased or generated repeatedly, forming air flow at the suction and exhaust ports of the blower

Instructions for use of water treatment aeration high pressure fan:
1
Installation location: it must be installed indoors where it is not disturbed by wind and rain
2
Ambient temperature: below 40 ℃
3
Relative humidity: below 80%
4
Air quality: if the air contains corrosive or flammable gases such as acid and alkali, it should not be transported by high-pressure blower to avoid danger
5
Dust protection: avoid using in places with a large amount of dust, powder or fiber
If it is necessary to use in such places, please install a filter and regularly clean the dust attached to the filter screen and high-pressure blower
6
Ventilation and heat dissipation: please use it in a well ventilated place, not in a closed room or box
7
Storage space: for the convenience of maintenance or repair, please avoid installing in a too narrow place
8
Avoid vibration: please install it in a place without vibration; If the site vibration is unavoidable, anti vibration measures shall be added to prevent the high-pressure blower from being damaged by external vibration
Key points for use of sewage aeration vortex fan:
When the high-pressure fan is running, the current consumed by the motor will increase with the increase of pressure and vacuum
If the current is too high, it will cause tripping
In order to prevent tripping or save power, please increase the cross-sectional area of the air outlet as much as possible, or install the air pressure and air volume regulating valve on the suction or exhaust side
A
For air supply - the inlet shall be equipped with a filter
1
The total cross-sectional area of the air outlet shall be greater than half of the cross-sectional area of the fan outlet
2
If it is used for air supply in water, the water depth pressure shall be less than 70% of the maximum static pressure value marked on the type record
3
During pressurized air supply, it is normal that the outlet temperature is 10 ℃ higher than the normal temperature due to air friction, so the iron pipe shall be used for more than 1m
B
For air suction - silencer can be installed at the outlet
The total cross-sectional area of the suction hole shall be greater than half of the cross-sectional area of the blower inlet

Working principle of aeration fan for sewage treatment
When the impeller 3 rotates, due to the action of centrifugal force, the wind vane urges the gas to move forward and outward, forming a series of spiral movements
The air between the impeller blades accelerates the rotation in a spiral shape and squeezes the gas outside the pump body into the side groove (inhaled by the suction port 1)
When it enters the side channel 2, the gas is compressed, and then returns to the impeller blades to accelerate the rotation again
When the air passes through the impeller and side slot along a spiral track, each impeller blade increases the degree of compression and acceleration
With the progress of rotation, the kinetic energy of the gas increases, further increasing the gas pressure passing along the side channel
When the air reaches the connection point between the side slot and the discharge flange (the side channel narrows at the outlet), the gas is squeezed out of the blade and discharged from the pump body through the outlet muffler 4

characteristic
Generally, the high-pressure blower has the following characteristics:
1
It has dual functions of blowing and suction
One machine can be used for both suction and blowing; There are a series of high-pressure blowers, which can also use suction and blowing at the same time, which is equivalent to the function of rotary vane vacuum pump;
2
When running with little or no oil, the output air is clean;
3
Compared with centrifugal fan and medium pressure fan, its pressure is much higher, often more than ten times that of centrifugal fan
At present, the maximum pressure is as high as 230kpa;
4
If the pump body is die cast as a whole and the shockproof mounting foot seat is used, its requirements for the installation foundation are also very low
It can even operate normally without fixing the foot seat, which is very convenient and saves the installation cost and installation cycle;
5
Compared with other types of fans, such as Gaorui fan, its operation noise is lower, and the greater the power, the more obvious it is, and more than 5
5kW will be displayed;
6
Maintenance free use; Its loss parts are only two bearings, which basically do not need maintenance within the warranty period;
7
The mechanical wear of the high-pressure blower is very small, because there is no other mechanical contact part except the bearing, so of course, the service life is also very long
As long as it is under normal service conditions, there is no problem for 3 ~ 5 years
This is also the biggest reason for the popularity of high-pressure fans in China
