And cooling；The ventilation of boiler and industrial furnace and air inducing；Cooling in the apparatus of air conditioning and domestic electric appliance and ventilation；Paddy
It the drying of object and selects and recommends；Inflation and propulsion of wind-tunnel wind regime and aircushion vehicle etc., centrifugal blower are to be converted to potential energy according to kinetic energy
Principle is accelerated gas using high-speed rotating impeller, is then slowed down, is changed flow direction, kinetic energy is made to be converted into potential energy（Pressure）.
In one-stage centrifugal wind turbine, gas is from axially into impeller, and gas is radially redirected when flowing through impeller, subsequently into diffuser.
In diffuser, gas and changing flow direction and the increase of conduit section area make flow slowing down, and this decelerating effect is by kinetic energy
It is converted into pressure energy.Pressure, which increases, to be occurred mainly in impeller, next is happened at diffusion process.In Multi-stage centrifugal fan, use
Return channel allows airflow into next impeller, generates higher pressure, the shell of centrifugal blower is the necessary item for ensureing its normal operation
One of part, but existing centrifugal blower shell is mostly directly to fix its surface using bolt, to complete to protect to it
Effect, existing mounting means have the shortcomings that mode is single.
Utility model content
The technical problems to be solved in the utility model be overcome existing centrifugal blower shell mostly be using bolt it is directly solid
Its fixed surface, to complete to carry out protective effect to it, existing mounting means has the shortcomings that the problem of mode is single, provides
A kind of centrifugal fan casing of multi-angle installation.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
The utility model provides a kind of centrifugal fan casing of multi-angle installation, including casing ontology, impeller placing groove,
Air outlet, holder, pedestal, sucker, sealing lip, gas pipeline, vacuum pump and fixed frame, the surface of the casing ontology are equipped with
The side of the impeller placing groove, casing ontology is equipped with the air outlet, and the casing ontology passes through described in holder connection
The bottom end surface of pedestal, the pedestal is equipped with the sucker, and the sucker is internally provided with the gas pipeline, the appendix
Road one end is equipped with the vacuum pump, and the surface bottom end surface of the sucker is additionally provided with the sealing lip.
As a kind of optimal technical scheme of the utility model, the surface of the gas pipeline is additionally provided with the fixed frame,
The fixed frame is used with the gas pipeline and is connected and fixed.
As a kind of optimal technical scheme of the utility model, the sucker is four groups, and sucker is uniformly distributed described in four groups
In the bottom end surface of the pedestal.
As a kind of optimal technical scheme of the utility model, the surface of the pedestal is additionally provided with controller, the control
Device is electrically connected with the vacuum pump.
As a kind of optimal technical scheme of the utility model, the vacuum pump and the fixed frame are bolted
On the surface of the pedestal.
The advantageous effect that the utility model is reached is：The centrifugal blower shell of this kind of multi-angle installation is by using vacuum
Pump inhales suction cup interior at negative pressure, so that suction cup interior pressure is bigger than external pressure, so that sucker is firmly adsorbed on
Ground, to complete the simple installation to centrifugal blower shell so that it can quickly be fixed on the outer surface pair of centrifugal blower
It is protected, and solves that existing centrifugal blower shell is single to be fixed by bolts, caused by fixed form is single lacks
It falls into.
