Roots blower fan model parameters to find the cities of Kun Hing blower

Roots blower is a positive displacement blower, through the "engaged" a pair of rotors (there is a gap between the rotor and do not touch each other) so that the air inlet separated by a pair of rotor synchronization gear, do the opposite direction, The inhalation of the gas compression without internal push from the suction port to the exhaust port. Gas reaches the instantaneous exhaust port, due to the high pressure side of the exhaust gas reflux is pressurized, thereby completing the gas delivery. Simply put, is to rely on one pair of impeller gas from one end to the other end of the mandatory stop delivery, to lose wind purposes. This principle is presented by American Roots brothers, so called Roots principle. Roots blowers manufactured using principle called Roots blower friends. Initially Roots blower rotor is a pair of two-lobe rotors, now basically have three leaves Roots rotor, in all aspects of noise, vibration, etc. have been greatly improved. But the basic principles remain unchanged. 1, the basic principle of the Roots blower is a dual rotor mechanical compression, parallel to the axis of the two rotors each other, a prime mover through a pair of synchronized gear drive, for constant rotation in the opposite direction. Positive displacement blower fan, air volume delivered in proportion with the number of revolutions, clover type impeller rotates once every two impellers by three times the suction and discharge. Driven synchronous gear wind turbine inlet conveyor from the rim to the side of the casing bi discharged. 2, the principle of pre-pre-intake inlet compression method, primarily to improve the impact properties reflux fan initiative. In primitive volume (the impeller and the casing and the wall of the closed space surrounded by) the process of moving from the intake port to the exhaust port through the opening in the casing or wall of the guide holes mouth, previously introduced into the inside thereof high-pressure gas, so that the volume in primitive communicated with the exhaust port before, so that the internal pressure gradually at or near equilibrium with the pressure exhaust port. Roots blower Features: 1, positive displacement blower fan, air volume delivered is proportional to the number of revolutions. 2, clover-type impeller rotates once every two impellers by three times the suction and discharge. Compared with the two leaf type, gas pulsation is small, too small vibration, low noise. 3, those between the impeller shaft and fan two oval hole surface casing, impeller end and front cover and fan impeller fan always keep a slight gap, driven synchronous wind gear rim into the wind from the fan housing the body wall to the side discharge conveyor. 4, each branch by the synchronization gear wheel always maintain correct phase, will not touch each other and, therefore, can be speeded up. 5. Fan cavity does not need oil, simple structure, stable operation, stable performance, adapt to a variety of purposes, has been applied to a wide range of fields.
