Description
Technical field
The invention belongs to Fan Equipment technical field, relate to a kind of two section type high pressure blower.
Background technology
Air blast is main by motor, air cleaner, impeller, air chamber, base etc.
Parts form, and draw air into by the volume change between blade, compress, spue, by
Operate without friction in body in impeller, it is not necessary to lubrication, make the gas not oil-containing of discharge,
It it is the industry such as chemical industry, food preferably Geldart-D particle source of the gas.During use, along with pressure
Change, flow variation is the least, but flow changes along with rotating speed, the therefore selection of pressure
Scope is the widest, and the selection of flow can reach needs by selecting rotating speed.Blower type
Various, can be divided into Shandong formula air blast, high pressure blower etc., wherein high pressure blower,
Also being high pressure positive blower, it is internally installed has fan blade, when fan blade rotates, due to centrifugal force
Effect, wind vane promotes gas to move out forward, thus forms a series of helical form
Motion, the air between fan blade blade in the shape of a spiral accelerate rotate and by outside the pump housing
Gas clamp-ons side channel, and after its approaching side passage, gas is compressed, and replys the most again
Again speeding up rotation between impeller blade, each impeller blade adds compression and the journey accelerated
Degree, along with the carrying out rotated, the kinetic energy of gas increases so that the gas passed through along wing passage
Body pressure increases further, and final gas is extruded blade and discharges the pump housing by outlet.
High pressure blower can need to increase fan blade and the quantity of wind bucket, i.e. multistage according to power
Formula air blast.
As Chinese invention patent application (application number: 200510091170.6) discloses one
Plant the multiple-stage centrifugal fan of middling speed high pressure, there is vertical subdivision housing structure, on main shaft
Being provided with the impeller of multiple aluminium or steel, main shaft is by the bearing housing of cylinder body one end and the other end
Cluster gear case supported.Cluster gear case, as a part for fermented soya beans, salted or other wise blower fan cylinder body, can
With raising wheel speed to obtain higher pressure, meanwhile, axial impeller wheel cap seals permissible
Reduce gap and improve the reliability in high-voltage applications, but owing to above-mentioned air blast is many
Individual impeller is all connected in rotating shaft, and during electric motor starting, multiple impellers work simultaneously,
When needing relatively low to the power of air blast, the use of above-mentioned air blast is more wasted.
Summary of the invention
The present invention is directed to existing technology and there are the problems referred to above, it is proposed that a kind of two section type is high
Drum pressure blower fan, fan blade can be disassembled and be transformed into list by this two section type high pressure blower
Machine air blast, uses more flexibly, conveniently.
The purpose of the present invention can be realized by following technical proposal: a kind of two section type high pressure
Air blast, including motor, front wind bucket and rear wind bucket, described motor, rear wind bucket, front wind
Bucket is fixedly connected with successively, is rotatably connected to rear rotating shaft in described rear wind bucket, described rear rotating shaft with
The output shaft of motor is fixedly connected with, fan blade after being connected in rear rotating shaft, it is characterised in that institute
State and be fixed with bearing holder (housing, cover) between motor and rear wind bucket, in described bearing holder (housing, cover), be fixed with rear bearing,
The output shaft of above-mentioned motor passes rear bearing, is rotatably connected to front rotary shaft in described front wind bucket,
Described front rotary shaft is axially aligned with rear rotating shaft, and the freedom of one end of front rotary shaft and rear rotating shaft
End is removably fixed with, and described front rotary shaft is fixed with front fan blade.
Two fan blades of this pair of section air blast are worked by driven by motor simultaneously, and power is higher,
And need reduce power or use space less, when needing the volume reducing air blast,
Front wind bucket is disassembled from rear wind bucket, owing to front rotary shaft is removably fixed with rear rotating shaft,
Therefore it also is able to disassemble from rear rotating shaft, is so converted into single-stage blower, makes
With the most flexible and changeable, between motor and rear wind bucket, it is provided with bearing holder (housing, cover) simultaneously, motor
Output shaft is connected on the bearing in bearing holder (housing, cover), serves the output shaft of motor effectively
Supporting, therefore changing connecting between front rotary shaft and rear rotating shaft will not be to the output shaft of motor
Produce impact, it is to avoid the output shaft of motor and rotor occur transition, improper
Abrasion.
In above-mentioned two section type high pressure blower, on the free end end face of described rear rotating shaft
Offering the spliced eye that cross section is hexagonal, it is transversal that the end of described front rotary shaft has one
The Plug Division that face is hexagonal, described Plug Division is plugged in spliced eye.I.e. pass through grafting
Portion matches with spliced eye so that circumferentially fixed between front rotary shaft and rear rotating shaft, turns the most afterwards
Axle can be with front rotary shaft synchronous axial system, and front rotary shaft also is able to extract from rear rotating shaft,
Easy accessibility.
In above-mentioned two section type high pressure blower, solid between described front wind bucket and rear wind bucket
Being connected with middle windshield, described middle windshield offers front link slot on the side of front wind bucket,
Middle windshield offers rear link slot, described rear link slot bottom land on the side of rear wind bucket
Offer the through hole connected with front link slot, described rear rotating shaft insert after link slot, and
The end face of rear rotating shaft leans with rear link slot bottom land, and described front rotary shaft end connects before inserting
Access slot, and the end of front rotary shaft leans with front link slot bottom land, described Plug Division passes
Through hole is plugged in spliced eye.Front link slot on apoplexy lid with rear link slot respectively to front
Rotating shaft and rear rotating shaft are supported, and axially position both, it is to avoid front rotary shaft simultaneously
Front rotary shaft axial float is caused due to the fit clearance between rear rotating shaft, and then to rear
Rotating shaft produces instantaneous axial impact force, it is to avoid damage motor.
In above-mentioned two section type high pressure blower, the outer ring of described rear bearing and bearing holder (housing, cover)
Inwall clamping is connected, the output shaft of above-mentioned motor and bearing inner race tight fit, described bearing
It is fixed with in set and rear bearing is carried out spacing jump ring.I.e. the output shaft of motor is played guarantor
Protecting effect, whether the installation of front rotary shaft will not produce impact to motor.
In above-mentioned two section type high pressure blower, described front wind bucket side is also fixed with
Front windshield, described front windshield side has an annular groove, is connected in annular groove
Fore bearing, the end of above-mentioned front rotary shaft is had to be connected with fore bearing tight fit.Fore bearing is to front
Rotating shaft is supported and positions so that structure is more stable, and current spindle and front wind bucket are torn open
When unloading down, front windshield can be connected on rear wind bucket side.
In above-mentioned two section type high pressure blower, described front windshield, front wind bucket, apoplexy
Lid and rear wind bucket are worn by bolt and are fixed together.It is fixedly connected with by same bolt,
Easy accessibility, front windshield also is able to be connected with rear wind bucket, and applicability is strong.
Compared with prior art, this two section type high pressure blower has the advantage that
1, being removably fixed with rear rotating shaft due to front rotary shaft, front wind bucket can be from rear wind bucket
Disassemble, be converted into single-stage blower, use the most flexible and changeable.
