Abstract
The utility model discloses a high pressure direct-coupled double stage gas conveying blower, relating to a gas conveying blower, which solves the problems of complex structure, unstable performance, too low pressure, high noise and too large motor power of the prior gas conveying blower. A second impeller (5) of the utility model is arranged on the left side of a first impeller (4) in parallel, a flow deflector (6) is arranged between the two impellers, the impeller (5) is fixedly connected with the shaft of a motor (3), and the flow deflector (6) is fixedly connected with a baffle plate (9). The utility model adopts the double stage impellers and the flow deflector, therefore the utility model has the advantages that the power of the motor is reduced, a transmission mechanism is eliminated, the structure is simple, high pressure coefficient and low specific speed are adopted, the efficiency is high and the noise is low. The energy saving effect is good, the blower is simple, and is easy to be arranged and maintained. Compared with the traditional conveying blower, the noise of the conveying blower is reduced by 5 to 10 decibels, the environmental protecting noise standard is achieved, the electric power is saved by about 30 percents, and the efficiency of the conveying blower is improved by 30 percents.
Description
Technical field
The utility model relates to high pressure blower.
Background technique
Existing pressurized gas wind conveyer is made up of casing, intake grill, impeller, transmission group, motor and support, and complex structure, the matching of gas delivery blower fan is poor, unstable properties, pressure is on the low side, noise is big and the excessive problem of power of motor.
The model utility content
The utility model is on the low side for the complex structure, unstable properties, the pressure that solve existing gas delivery blower fan, noise is big and the excessive problem of power of motor, a kind of high pressure direct connection twin-stage gas delivery blower fan is provided, and the concrete technological scheme that addresses the above problem is as follows:
The utility model comprises casing 1, intake grill 2, motor 3 and first impeller 4, it also includes second impeller 5, guide plate 6 and dividing plate 9, second impeller, the 5 parallel left sides that are located at first impeller 4, dividing plate 9 is located at the centre of first impeller 4 and second impeller 5, guide plate 6 is fixed on the dividing plate 9, and second impeller 5 is fixedlyed connected with the arbor of motor 3.
The utility model adopts twin-stage impeller and guide plate, has reduced the power of motor, has saved driving mechanism, and is simple in structure, adopted the high pressure coefficient, low specific speed, high efficiency, low noise.Good energy-conserving effect, easy, easily install and keep in repair.This wind conveyer is compared with traditional wind conveyer and is reduced noise 5-10 decibel, reaches the criteria for noise of environmental protection, conservation of power about 30%, and the efficient of wind conveyer has improved 30%.
