Description
Technical field
The utility model relates to a kind of Fan Equipment technical field, particularly relates to a kind of convection rotary type flow blow.
Background technique
Ventilator is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, it is a kind of driven fluid machinery.Exhaust pressure is lower than 1.5 × 10 handkerchiefs.Ventilator is widely used in factory, mine, tunnel, cooling tower, vehicle, the ventilation of boats and ships and building, dust discharge and cooling, the ventilation of boiler and industrial furnace and air inducing, cooling in the apparatus of air conditioning and domestic electric appliance and ventilation, the oven dry of cereal and selecting and recommending, the inflation of wind-tunnel wind regime and Hovercraft and propelling etc.Ventilator is widely used in factory, mine, tunnel, cooling tower, vehicle, the ventilation of boats and ships and building, dust discharge and cooling; The ventilation of boiler and industrial furnace and air inducing; Cooling in the apparatus of air conditioning and domestic electric appliance and ventilation; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.
The working principle of ventilator is substantially identical with turbocompressor, and just because gas flow rate is lower, pressure change is little, does not generally need the change considering gas specific volume, namely using gas as incompressible fluid process.The relation of ventilator and blower fan: blower fan is that the custom of China to gas compression and gas conveying machinery is called for short, usually said blower fan comprises ventilator, blower, compressor and Roots blower, but do not comprise piston compressor isometric(al) formula blower and compressor.Ventilator is a kind of product type of blower fan, but people usually ventilation machine barrel being blower fan, both ventilator was another call of blower fan.The performance parameter of ventilator mainly contains flow, pressure, power, efficiency and rotating speed.In addition, the size of noise and vibration is also the key technical indexes of ventilator.Flow also claims air quantity, represents with the gas volume flowing through ventilator in the unit time.Pressure also claims blast, refers to that gas is at ventilator internal pressure lift-off value, have static pressure, dynamic pressure and total head point.Total head equals the difference of ventilator outlet and import cross section overdraught total head; Static pressure equals the difference of ventilator outlet and import cross section overdraught static pressure; Dynamic pressure refers to the dynamic pressure of ventilator outlet overdraught mean velocity.On same cross section, the total head of air-flow equals static pressure and dynamic pressure sum.Inconvenience installed and used by current existing air bells exhauster, for the air draft in colliery, has certain potential safety hazard.
