Abstract
The utility model relates to a centrifugal pipeline fan. A casing is square, both sides of the casing are provided with square pipe interface flanges, and an isolating layer is arranged in the casing. An impeller air inlet is arranged on the isolating layer, a volute and an external rotor motor provided with a backward bent impeller are arranged in the casing at the upper part of the isolating layer, the external rotor motor provided with the backward bent impeller is arranged on a leaf door, and the lower part of the isolating layer is provided with a flow guide plate. The utility model has the advantages of low noise and stable operation. Since the mode of the leaf door which can swing outward is used, the fan and pipelines do not need to be disassembled. So long as the leaf door is opened, the external rotor motor and the backward bent impeller can swing out, which is favorable to the cleaning and maintenance of the fan. In addition, the motor has the function of adjusting voltage, and the speed adjusting range is 100%-0%.
Description
Technical field
The utility model relates to a kind of pipeline fan, and is particularly relevant with centrifugal pipeline fan.
Background technique
There is following defective in existing centrifugal pipeline fan, and volume is big, heavy, noise height, manufacture cost is high and it is all inconvenient to install and repair.
Summary of the invention
Main technical schemes of the present utility model is as follows:
Casing is square, its both sides have the square pipe flange, at the inner separation layer of installing of casing, one impeller intake grill is arranged on the separation layer, in the separation layer upper housing volute and the external rotor electric machine that has backward inclined type of impeller, the external rotor electric machine that has backward inclined type of impeller is installed on the page or leaf door, and the separation layer bottom is a guide plate.
The utility model is compared with prior art, and its advantage is; Noise is low, operate steadily.Owing to adopt the mode of external swinging leaf door, so need not dismantle blower fan and pipeline, as long as open the page or leaf door, external rotor electric machine and backward inclined type of impeller just can be shown, and help the cleaning and the maintenance of blower fan.Motor has voltage-regulation function, speed adjustable range 100%-0% in addition.
Description of drawings
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is that the master of centrifugal pipeline fan looks cut-away view;
Fig. 2 is the maintenance user mode figure of centrifugal pipeline fan.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, 2, casing 11 is square, its both sides have the square pipe interface and send out blue 1, at the casing 11 inner separation layers of installing, one impeller intake grill 6 is arranged on the separation layer, be volute 10 and the external rotor electric machine 5 that has backward inclined type of impeller in the separation layer upper housing 11, the external rotor electric machine 5 that has backward inclined type of impeller is installed on the page or leaf door 4, and the separation layer bottom is a guide plate 8.When using this product, it is installed on the pipeline, starts power supply, the external rotor electric machine 5 that has backward inclined type of impeller is sucked air in the volute 10 by guide plate 8 and impeller intake grill 6 by intake grill 9, air is discharged outdoor by exhaust port 7 again.For the noise that reduces blower fan can be installed puigging 2 respectively before and after casing is about in the of 11, and the 2 other soundproof doors 3 of installing of the puigging on casing 11.When blower fan was cleaned in maintenance, as long as open page or leaf door 4, the external rotor electric machine 5 that has backward inclined type of impeller just can be shown, and cleaned and had safeguarded.
