1. Ventilation
Ventilation is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine.
Fans are widely used in ventilation, dust removal, and cooling of factories, mines, tunnels, cooling towers, vehicles, ships, and buildings; ventilation and drafting of boilers and industrial furnaces;
Cooling and ventilation in air-conditioning equipment and household appliances; drying and sorting of grain; wind tunnel wind source and inflation and propulsion of hovercraft, etc.
The working principle of the ventilator is basically the same as that of the turbo compressor, but because the gas flow rate is low and the pressure changes little, it is generally not necessary to consider the change of the gas-specific volume, that is, the gas is treated as an incompressible fluid.
2. Blower
Under design conditions, a fan with a wind pressure of 15kPa~0.2MPa or a compression ratio e=1.15~3 is called a blower.
Features:
1. Since the impeller runs without friction in the body, no lubrication is required, so the discharged gas does not contain oil. It is an ideal pneumatic conveying gas source for chemical, food and other industries.
2. The blower is a volumetric operation type blower. When in use, with the change of pressure, the flow rate changes very little. But the flow rate changes with the speed. Therefore, the selection range of pressure services is very wide, and the selection of flow rate can meet the needs by selecting the speed.
3. The speed of the blower is high, and the gap between the rotor and the rotor, and between the rotor and the body is small, so there is less leakage and higher volumetric efficiency. Our factory has strong processing and assembly technology, which can ensure a reasonable and uniform gap, achieve high volumetric efficiency and avoid friction in the body due to thermal expansion.
4. The structure of the blower determines that its mechanical friction loss is very small. Because only the bearing and the gear pair have mechanical contact in the material selection, the rotor, casing, and gear ring have sufficient mechanical strength. Safe operation and long service life are major features of blower products.
