Vacuum suction blower

Vacuum suction blower
Working principle of suction fan:
The common medium pressure fan is a centrifugal fan, whose impeller is covered with a mechanical shell and the center of the impeller is the air inlet. When the medium pressure fan is working, the power equipment drives the impeller to rotate, drawing air in from the air inlet. During the rotation of the blades of a centrifugal fan, a dynamic force is applied to the gas, increasing its pressure and velocity. The gas is discharged from the exhaust port along the blade path under the action of centrifugal force.
During the operation of a medium pressure fan, although the rotation of the impeller increases the pressure and velocity of the gas, the various changes in the gas are relatively small. Therefore, in the design and use of centrifugal fans, gas is usually treated as an incompressible fluid. The gas treatment process of medium pressure fans is completed in the same radial plane, so medium pressure fans are also called radial centrifugal fans

Among the performance parameters of a medium pressure fan, the most important ones are gas flow rate, pressure, conveying power, efficiency, and impeller speed, which must be taken into account during the selection process. The gas flow parameters of a medium pressure fan represent the volume of gas that the fan can process per unit time, while the pressure of a medium pressure fan refers to the internal gas pressure value during its operation.

The efficiency of a medium pressure fan refers to the ratio between the shaft power of the fan and the actual effective power of the processed gas. The total pressure efficiency of centrifugal fans is about 90%, and in the future development of centrifugal fans, efficiency value will be one of the goals further pursued by researchers.
4. In practical applications, medium pressure fans are widely used for dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings; Ventilation and induced draft for boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household appliances; Drying and selection of grains; Wind tunnel wind source and inflation and propulsion of hovercraft.

When using a medium pressure fan, attention should be paid to cleaning the dust on the surface of the fan, checking and cleaning the bearings, and tightening all bolts. Check the air inlet and outlet, adjust the tightness of the V-belt, inspect the lubrication parts, replace the lubricating oil and sealing ring.
6 Precautions: 1. If the flow rate is found to be too high, does not meet the usage requirements, or requires a smaller flow rate in a short period of time, a throttling device can be used to adjust it.
2. Regularly check the sensitivity of thermometers and oil gauges, and control the oil level in the bearing box within the specified allowable range.
3. If any abnormal phenomenon is found during the driving, parking or operation of the fan, it should be checked immediately.
4. For minor faults discovered during inspection, the cause should be promptly identified and efforts should be made to eliminate or handle them. If minor faults cannot be eliminated or major faults are discovered, immediate inspection should be carried out.
5. In addition to replacing the lubricating oil after each disassembly and repair, the lubricating oil should also be replaced regularly.
6. The bearing seat of E-type transmission should be regularly (quarterly) inspected, cleaned, and lubricated to prevent bearing burnout.

The main products are the Touareg CX-1/4 blower, medium pressure CX-75S blower, CX-75 blower, CX-100 blower, CX-125 blower, CX-150 blower, CX-180 blower, and so on.
Medium pressure, air volume, low noise, lightweight; Due to the frictionless operation of the impeller within the body, no lubrication is required, resulting in the exhaust gas being oil-free. It is an ideal pneumatic conveying gas source for industries such as chemical and food. Using aluminum alloy material to significantly reduce weight and achieve the goal of lightweighting; When in use, the flow rate changes very little with changes in pressure. Special blade design, low noise, long lifespan, suitable for pressure and air flow. In terms of material selection, the rotor, casing, and gear ring have sufficient mechanical strength. Safe operation and long service life are major features of blower products

It is an ideal pneumatic conveying gas source for industries such as chemical and food. Using aluminum alloy material to significantly reduce weight and achieve the goal of lightweighting; When in use, the flow rate changes very little with changes in pressure.

Precautions for use:
Both aspects require protection: pressure and dust.
For pressure, a pressure relief valve is often used, which is an unloading valve. When the operating pressure of the high-pressure fan exceeds the set pressure of the pressure relief valve, the pressure relief valve will automatically open to release the excess pressure and protect the high-pressure fan.
For dust, filters are often used. It often uses filter cartridges with different filtration accuracies according to different usage scenarios. Different filter cartridges have different maintenance methods and service lives, which need to be clarified when ordering.
In some special occasions, special protection is also necessary: for example, when using in a sealed environment, attention should be paid to ventilation and heat dissipation; When the ambient temperature (intake temperature is relatively high), it is more important to pay attention to ventilation and heat dissipation, or choose a high-pressure fan that allows for a higher intake temperature (such as a temperature resistant high-pressure fan that allows for an intake temperature of up to 70 degrees); For fans, there may be their own usage suggestions, so it is important to have a detailed understanding before purchasing.
