If special voltage is required, it can be customized according to requirements.

Working principle of material fermentation aeration fan

After the power is turned on, the fan rotates. Due to the groove design of the impeller, it will drive air flow. Therefore, air enters the pump body through the inlet, and the air is stirred inside. Each groove is pressurized by a vortex, and a powerful airflow energy is formed through a cycle of pressurization. It is discharged from the pump body through the outlet for use.

Configuration of material fermentation aeration fan
1. Shell material: Made of * degree die cast aluminum, which is the same aluminum material as Mercedes Benz wheel rims. Compared to ordinary aluminum alloys, die cast aluminum is stronger and has a more lightweight effect compared to iron shell fans. 2. Motor performance: Adopting a motor, the motor is a wide frequency, wide voltage motor, listed as single-phase 110V, 230V; Industrial three-phase 220V, 380V, 415V, 660V, etc., motor frequency adjustable from 45-75HZ, IP55 protection level F insulation level,

Structure of material fermentation aeration fan

1. Impeller: Adopting a gradually opening linear surface for high volume utilization. 2. Bearing: 3000 type double row radial spherical roller bearings are selected as the positioning end near the coupling end. 32000 type single row radial short cylindrical roller bearings are selected as the free end near the gear end to adapt to the axial displacement of the rotor during thermal expansion. 3. Body: Composed of a casing and left and right wall panels. The left and right wall panels, as well as the bearing seats and sealing parts installed inside the left and right wall panels, can be interchangeable. 4. Base: Both small and medium-sized fans are equipped with a common base, while large fans are only equipped with a fan base for easy installation and debugging. 5. Transmission mode: mainly through direct coupling of couplings. If performance specifications require it, the method of variable speed with triangular pulleys can also be chosen. Elastic couplings are selected for the coupling, which can alleviate impact and compensate for a small amount of axis deviation. Large flow fans can also be driven by steam turbines or other types of motors, in addition to electric motors.

Characteristics of material fermentation aeration fan

1. Circulating pressurization design, high pressure, sufficient air volume; 2. Small starting torque, stable and reliable working process; 3. Airflow buffering design, low noise; 4. Oil free lubrication, purer gas; 5. Surface phosphating treatment, electrostatic spraying, uniform color, stronger adhesion; 6. Wide range of power configuration and long product lifespan.

Working characteristics of material fermentation aeration fan:

1. It has dual functions of suction and blowing, and one machine can achieve suction and blowing. 2. Run with little or no oil, and the output air is clean; Compared to centrifugal fans and medium pressure fans, their pressure is much higher, often more than ten times that of centrifugal fans. Currently, the pressure can reach up to 100KPA; If the pump body is die cast as a whole and shockproof mounting feet are used, the requirements for the installation foundation are also very low. It can operate normally without fixing the feet, which is very convenient and saves installation costs and installation cycles; 5. Compared to other types of fans, its operating noise is lower, and the higher the power, the more obvious it is. It will be displayed above 5.5KW; 6. Maintenance free use; Its consumable parts are only two bearings, which basically do not require maintenance within the warranty period; 7. The mechanical wear of the vortex fan is very small because there are no other mechanical contact parts except for the bearings, so the service life is naturally very long. As long as it is under normal operating conditions, 3-5 years is no problem. 8. Easy to install and use!

Material fermentation aeration fan

Due to the widespread use of high-pressure fans, their selection is also relatively complex. Generally speaking, the following two steps need to be followed: 1. Determine the function of the high-pressure fan used on site, whether it is suction or blowing, and find the corresponding pressure flow curve of the high-pressure fan; If the curve is misread, sometimes the selected product cannot be used; 2. Based on the calculated pressure and flow rate, find the working curve above the corresponding working point that satisfies both pressure and flow rates on the curve graph; Then select the high-pressure fan model based on the working curve; As long as it is a different work site, its requirements for pressure and flow rate are different, so in order to obtain relatively accurate data, relevant calculations need to be carried out. This needs to be done by professional designers or consulted with professional companies.

Installation of material fermentation aeration fan

1. Flat washers and spring washers must be used to tighten screws; 2. Can use rubber buffer to withstand the weight of high-pressure fans, especially high-power high-pressure fans, *; 3. For certain occasions where noise is required, noise reduction * can be installed to reduce noise (usually around 5dB), and the noise reduction * can be installed at the end of the inlet or outlet duct; 4. For certain occasions with high noise requirements, a layer of soundproofing foam can be added according to the conditions of the machine itself to meet the on-site noise requirements. For specific details, please consult the manufacturer of the high-pressure fan or a professional noise control company; 5. When using sound-absorbing foam, pay attention to the distance between the high-pressure fan and the box, the ventilation and heat dissipation of the high-pressure fan, and the use of rubber buffer to bear the weight of the high-pressure fan. Please consult the manufacturer of the high-pressure fan for specific details. 6. The inlet and outlet pipes of the high-pressure fan should be connected with hoses to isolate vibration.

Different usage sites often use filter cartridges with different filtration accuracies, and different filter cartridges have different maintenance methods and service lives. It is necessary to clarify this when ordering.
