Under the design conditions of high-pressure blowers, fans with a wind pressure of 30kPa~200KPa or a compression ratio of e=1.3~3 belong to the category of high-pressure blowers. At present, the gas ring vacuum pump is generally classified as a high-pressure blower in the industry. High-pressure blower, also called high-pressure blower, is different from general centrifugal high-pressure blower. The high-pressure blower is small and easy to carry; besides the impeller, the high-pressure blower has no other moving parts, and the impeller is directly connected to the motor, without gears or driving belts, so it is highly reliable and almost maintenance-free.
Industry printing machinery, burners, bag blowing machines, plastic extrusion machines, fruit making machinery, dust collectors, environmental machinery, woodworking machinery, hot air generators, powder conveyors, kitchens applicable to high-pressure blowers Mechanical machine, dryer, incinerator, constant temperature box, mechanical cooling, general suction and air supply. The ventilator 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.
Ventilators are widely used in ventilation, dust extraction and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air for boilers and industrial furnaces; air conditioning equipment and household appliances Cooling and ventilating; drying and selective delivery of grain; inflating and propelling the wind source of wind tunnel and hovercraft.
The working principle of the ventilator is basically the same as that of the turbo compressor, except that the gas flow rate is low and the pressure changes little. Generally, there is no need to consider the change of the gas specific volume, that is, the gas is treated as an incompressible fluid.
1. Because the impeller runs in the machine body without friction and does not need lubrication, the discharged gas is oil-free. It is an ideal pneumatic conveying gas source for chemical, food and other industries.
2. The high-pressure blower is a volume-operated blower, and its use time varies with pressure. The flow rate changes very little. But the flow rate changes with the speed. Therefore, the selection range of pressure is very wide, and the selection of flow rate can be achieved by selecting the speed.
3. The high-pressure blower has a high speed, and the gap between the rotor and the rotor, between the rotor and the body is small, so that there is less leakage and higher volumetric efficiency. Our factory has strong processing and assembling technology, which can ensure the reasonable and uniform gap, and achieve high volumetric efficiency without friction in the machine body due to thermal expansion.
