Abstract

The invention discloses an adjusting device of an air feeder. The adjusting device comprises an inner ring of a blade of the air feeder; the inner ring of the blade of the air feeder is provided with a replaceable adjusting belt with width direction vertical to the back of an impeller; the replaceable adjusting belt is of a circular shape; a protrudent fixing ear is arranged on the replaceable adjusting belt; and the fixing ear is inserted into a groove of the back of the impeller. The adjusting device has a reasonable structure, effectively changes the effective width of the blade and does not need to replace the air feeder or make great change, thereby making air feeding parameters of the air feeder reach the requirement of performance parameters of an air conditioning unit.

Description

Technical field: [0001] The invention relates to a blower regulating device. Background technique: [0002] We always want the performance of the blower to match the parameters required by the air conditioning unit. At present, there are two ways to adjust the parameters of the blower to make it consistent with the requirements of the air conditioning unit. [0003] The first method is to use an adjustable-speed motor unit instead of a single-speed motor, but the cost of installing a speed-adjustable motor is higher, and the maintenance cost is also high. At the same time, installation of a speed-adjustable motor or a variable-frequency drive motor requires great care. [0004] The second method is to adjust the width of the blades. This requires replacing the original impeller with a new one, which is costly and time consuming. Invention content: [0005] The purpose of the present invention is to provide a blower regulating device which has a reasonable structure and m...
