Abstract
The utility model discloses a kind of adjustable type spiral case, including spiral case, impeller, diffuser and current collector, the current collector is connected with spiral case, and in spiral case, diffuser is fixed in spiral case wheel rotation；Toroidal membrane is provided with the inner chamber of the spiral case.The utility model makes blower fan passage component matching good by changing the toroidal membrane of different width long, in hgher efficiency.
Description
Technical field：
The utility model is related to a kind of adjustable type spiral case.
Background technology：
Cfentrifugal blower or compressor collect compressed media, the spiral case and different shaped of existing single model by spiral case
Number impeller and other passage components matching it is poor, under equal flow, it is impossible to while meeting low-pressure and high pressure
Duty requirements；When the spiral case of pressure common power blower fan is used for high pressure blower fan, pressure at expulsion can be caused not enough, to overall efficiency not
Profit.
Therefore, it is necessory to be improved to solve the deficiency of prior art to prior art.
Utility model content：
The utility model is to provide a kind of adjustable type spiral case to solve the problems, such as above-mentioned prior art.
The technical scheme that the utility model is used has：A kind of adjustable type spiral case, including spiral case, impeller, diffuser with
And current collector, the current collector is connected with spiral case, and in spiral case, diffuser is fixed in spiral case wheel rotation；
Toroidal membrane is provided with the inner chamber of the spiral case.
Further, the internal chamber wall of the spiral case is provided with positioning step, and toroidal membrane is provided with and the positioning step phase
The groove of adaptation.
Further, the toroidal membrane is fixedly connected by sunk screw with spiral case.
Further, the toroidal membrane is made of aluminium alloy or stainless steel.
The utility model has the advantages that：The utility model is made by changing the toroidal membrane of different width long
Blower fan passage component matching is good, in hgher efficiency.
Brief description of the drawings：
Fig. 1 is the utility model sectional structure chart.
Fig. 2 is the sectional structure chart of toroidal membrane in the utility model.
Specific embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of adjustable type spiral case of the utility model, including spiral case 1, impeller 2, diffuser 3 and
Current collector 5, current collector 5 is connected with spiral case 1, and impeller 2 is rotated in spiral case 1, and diffuser 3 is fixed in spiral case 1.
Toroidal membrane 4 is provided with the inner chamber of spiral case 1.The utility model is that toroidal membrane 4 preferably is positioned at into spiral case 1
It is interior, positioning step 11 is provided with the internal chamber wall of spiral case 1, ground is corresponded, it is provided with toroidal membrane 4 and the positioning step
11 grooves 41 being adapted.
Toroidal membrane 4 in the utility model is fixedly connected by sunk screw with spiral case 1, is between the two detachable knot
Structure, is easy to be changed according to different pressure the toroidal membrane 4 of different width long.
Toroidal membrane 4 in the utility model is made of aluminium alloy or stainless steel.
The process of blower fan or compressor operating compression gas medium：From the air inlet of current collector 5, through the blade and wheel hub of impeller 2
Rotation acting, medium velocity is raised, and into diffuser 3, speed is gradually reduced, and pressure is gradually increasing, and is carried out subsequently into spiral case 1
Collect, finally exported from spiral case 1 and discharged, to user pipe.When low-pressure spiral case 1 is used for high pressure blower fan, it is only necessary to change not
With the toroidal membrane 4 of width long, you can meet the Fan Product of different pressures.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
Protection domain of the present utility model.
