Place, described air outlet is provided with the choked flow muscle, by the choked flow muscle, dirty air duct inside is divided into the pipeline of different internal diameters, mates different motors.
Described air outlet is provided with 1, and described suction port is provided with a plurality of.
Described suction port is two, comprises the first suction port and the second suction port, described the first suction port and the second suction port flanged structure for stretching out downwards.
The middle part of described the first suction port arranges the first choked flow muscle, and the first suction port is divided into two admission lines; In the middle part of described the second suction port, the second choked flow muscle is set, the second suction port is divided into two admission lines; The middle part of described air outlet arranges the 3rd choked flow muscle, and the air outlet is divided into two outlet pipes.
Described the first choked flow muscle extends to the inside of the first suction port from the outlet end of the first suction port, described the second choked flow muscle is arranged on the inside of the second suction port, and the outlet end of described the 3rd choked flow muscle from the air outlet extends to the inside of air outlet.
The middle part of described the first suction port arranges the first choked flow muscle, and the first suction port is divided into two outlet pipes; The second choked flow muscle is set in described the second suction port; The middle part of described air outlet arranges the 3rd choked flow muscle and the 4th choked flow muscle, and suction port is divided into three admission lines.
Described the first choked flow muscle extends to the inside of the first suction port from the outlet end of the first suction port, described the second choked flow muscle is in the inner transverse setting of the second suction port, and described the 3rd choked flow muscle and the outlet end of the 4th choked flow muscle from the air outlet extend to the inside of air outlet.
Compared with prior art, due to the size of the caliber noise different to the generation of motor, the larger noise of caliber is larger, and the less noise of caliber is less.And caliber is also very obvious on the impact of charge flow rate, and the larger air inlet flow resistance of caliber is less, and vice versa.The difference of the utility model by the choked flow muscle forms different calibers and can obtain different air inlet flow resistance and noise characteristic, specifically has the following advantages:
(1) can form by the variation of choked flow muscle the dirty air duct of various different tube diameters;
(2) in the application with the product of platform seriation, in the situation that part shape changes is very little, realize sharing and sharing of die of part.
