Medium pressure centrifugal fan

Medium pressure centrifugal fan

Medium pressure centrifugal fanAdopting ADC12 material similar to Mercedes Benz's wheel drum, it transcends the outdated casting process of pig iron, and the impeller does not come into contact with other components, resulting in no oil or pollution.

The selection method is the same as that of high-pressure fans. Generally speaking, the following two steps need to be followed:
1. Need to determine what function of the high-pressure fan is 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.

Application: 1. Air suction function: screen printing machine adsorption, welding exhaust gas suction, weaving machine silk suction, photographic plate making, powder particle conveying, printing adsorption, industrial vacuum suction, vacuum dehydration, book making machine, residual cloth treatment, milk carton filling machine, tofu machinery, maintenance of processed materials, construction site, ironing machine, gas decomposition. 2. Blowing function: Gas and heavy oil spraying, bottle washing machine drying, paper and cloth strip blowing, air knife for drying, cutting machine air cushion, livestock manure fermentation explosion, conveying, electrolyte stirring, oxygen supply for breeding pool, convenient punching machine for taking formed products, powder conveying, incinerator waste disposal, smoke blowing and suction, car washing and drying, forced drying of printing machine, washing and drying.

Precautions for use:
Overload phenomenon occurs when fully closed (RB series).
When fully open, overload phenomenon may occur (CX, TB, HTB, CS, PF, MS series). At this time, use an ammeter to confirm the current size and adjust the buffer. It is usually used within the fixed current range.
Repeatedly opening and closing the switch within one minute can cause the motor to overheat and should be avoided.
Variable frequency drive control - When using a variable frequency drive, the power waveform is distorted, the motor sound is loud, and the vibration is also significant. If using a frequency converter for operation and the temperature rises or there is significant vibration, please stop running. Please use it under the following conditions.
The maximum frequency value (number of rotations) must be within the specified frequency range indicated on the label and within the fixed current range.
Zui small cycle wave number (rotation number) - above 30 Hertz (Hz) and within the freezing current.
Single phase motors cannot operate as frequency converters.

The research and design of the product adopt *, utilizing ADC12 aluminum for one-time die casting and high-precision CNC machining;
2. The insulation level of the motor is TEFC IP55 standard, with an insulation level of H, and the body can withstand temperatures up to 180 degrees;
3. The motor meets the European EFF2 standard, which is particularly energy-efficient and durable;
4. The new design of the front bearing ensures that our product is highly dynamic and stable during operation;
5. The impeller is directly connected to the motor shaft, requiring no other accessories during rotation, no friction during operation, and no internal lubrication. Therefore, the output air is oil-free, pure, and environmentally friendly;
6. High performance sealing rings effectively prevent foreign objects from entering the body, effectively improving the product's service life;
7. After testing, the fan can operate smoothly and quietly for a long time, and the company provides multiple power and size options for selection;
8. The products undergo strict testing and verification before leaving the factory to ensure the efficiency of customer use.
