Problems solved by technology
In practice, there may be surface deformation or surface unevenness during the processing of centrifugal fan blades, and the assembly of the dehumidifier air duct components by employees is not in place or the coaxiality of the motor and centrifugal fan blades does not meet the accuracy Requirements and other factors lead to the failure of the centrifugal fan blade
The unqualified centrifugal fan blade will cause the problem of its shaking up and down during operation, which will cause the centrifugal fan blade to vibrate greatly or make noise, which will affect the service life of the air duct components of the dehumidifier

Embodiment Construction
[0024] The core of the present invention is to provide a detection device for centrifugal fan blades to detect whether the centrifugal fan blades are qualified, so as to improve the service life of the air duct components of the dehumidifier.
[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] Please refer to Figure 1-Figure 4 As shown, the embodiment of the present invention discloses a centrifugal fan inspection device for checking whether the centrifugal fan 4 of the air duct of a dehumidifier is qualified, which includes: a base 1 and a positioning block 2 . Wherein, the base 1 is used as a supporting platform of the whole inspection device, and can be fixedly installed on the workbench. In order to check whether the lower surface 42 of the centrifugal blade 4 is flat, the surf...

The invention provides an inspection device of a centrifugal fan blade. The inspection device comprises a base and a positioning block. The base can be opposite to the lower surface of the centrifugal fan blade, and the surface, connected with the centrifugal fan blade, of the base serves as a lower reference plane. The positioning block can be opposite to the upper surface of the centrifugal fan blade, the surface, connected with the centrifugal fan blade, of the positioning block serves as an upper reference plane, the upper reference plane and the lower reference plane are parallel and used for containing the centrifugal fan blade, and the distance from the upper reference plane to the lower reference plane is equal to a preset height. The lower surface of the centrifugal fan blade is opposite to the lower reference plane of the base, and the upper surface of the centrifugal fan blade is opposite to the upper reference plane of the positioning block. In the rotating process of the centrifugal fan blade, the preset height is set according to the height of the qualified centrifugal fan blade, if the detected centrifugal fan blade collides with the positioning block or the base, it shows that installing of the centrifugal fan blade is not qualified or the centrifugal fan blade is not qualified; if the centrifugal fan blade smoothly rotates, it shows that the centrifugal fan blade is qualified. Whether an air duct part of a dehumidifier is qualified or not is detected through the inspection device, and therefore the service life of the air duct part of the dehumidifier is prolonged.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a testing device for centrifugal fan blades. Background technique [0002] Dehumidifiers, also known as dehumidifiers, dryers, and dehumidifiers, are a small member of the refrigeration and air-conditioning family. Usually, dehumidifiers include compressors, heat exchangers, fans, water containers, casings, and controllers. The working principle is: the humid air is sucked into the machine by the fan, passes through the heat exchanger, so that the moisture in the air is condensed into water drops, and the dry air after treatment is discharged outside the machine, so that the indoor humidity is reduced by such a cycle. [0003] The air duct components of the dehumidifier mainly include a volute, a motor, and a centrifugal fan. During installation, the centrifugal fan is connected to the motor and then installed on the volute. In practice, there may be surface deformation...
