Pump is after object is cut in absorption, and during cutting, airflow pressure changes greatly, when being cut object and cutting to half, it may appear that air quantity
The insufficient situation of wind pressure makes to be cut object appearance movement and can not continue to cut, then needs to improve power of fan if desired for continuing to cut,
General 10kw~the 50kw that improves can just be met the requirements, so as to cause unnecessary waste.
Utility model content
It is rational in infrastructure the purpose of this utility model is to provide a kind of high speed air pump, during object is cut in cutting
It can require to change air quantity according to cutting, and wind pressure variation is small, can meet what is entirely cut in the case where not influencing to cut precision
Process.
Technical solution is used by the utility model will solve its technical problem：A kind of high speed air pump, including the pump housing, pump
Shell has variable-frequency motor in the pump housing, is connected with protecgulum in pump housing one end, and the other end is connected with rear cover, in the variable-frequency motor
Pump shaft one end be connected with impeller through protecgulum, impeller is equipped with gland and passes through screw and gland is fixed on impeller, pump shaft
The other end is sequentially installed with fan blade and baffle ring, and fan blade is placed in the rear cover；The pump case is connected with protecgulum, is had on pump case
Air inlet and gas outlet, the impeller are placed in pump case and at the bead of air inlet.
As the further setting of above-metioned scheme：The protecgulum includes pedestal, and pedestal is equipped with truncated cone-shaped skull, makes pump case
It is interior that there is enough air passing spaces, air mass flow can be increased.
The impeller include wheel disc, on wheel disc be equipped with axle sleeve and wheel disc one side and on the axle sleeve lateral wall uniformly
Equipped with several blades, blade is in herringbone cambered design, and for blade according to fluid mechanical design, when wheel rotation can improve air mass flow
And air velocity, the interlobate passage is expanded from inside to outside, when air flows through passage, can be done work to air, into one
Step improves air velocity.
The top apex of several blades is placed at the bead of air inlet, and is set to by separation of tip to outer portion
And inward portion, blade make pump case coordinate compacter conjunction with impeller to the symmetrical cooperation of arc trend inside outer portion and pump case
Reason, can improve air quantity, meet entire cutting process to greatest extent.
The pump shaft is equipped with 2 bearings, and 2 bearings are separately mounted in protecgulum and rear cover, rotates pump shaft more steady
It is fixed reliable.
With the above structure, the utility model is rational in infrastructure, can be required during object is cut in cutting according to cutting
Change air quantity, and wind pressure variation is small, and the process entirely cut can be met in the case where not influencing to cut precision.

Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
As shown in Figure 1, a kind of high speed air pump, including the pump housing 1, pump case 11, has variable-frequency motor 2, in the pump housing in the pump housing 1
1 one end is connected with protecgulum 3, and the other end is connected with rear cover 4, and 5 one end of pump shaft in the variable-frequency motor 2 is connected with through protecgulum 3
Impeller 6, impeller 6 are equipped with gland 7 and pass through screw 8 gland 7 is fixed on impeller 6, can be with impeller when pump shaft 5 rotates
6 quick rotations, 5 other end of pump shaft are sequentially installed with fan blade 9 and baffle ring 10, can be to the frequency conversion in work by the rotation of fan blade 9
Motor 2 radiates, and fan blade 9 is placed in the rear cover 4；The pump case 11 is connected with protecgulum 3, has 12 He of air inlet on pump case 11
Gas outlet 13, the impeller 6 are placed in pump case 11 and at the bead of air inlet 12, can improve wind speed and wind to greatest extent
Amount.The protecgulum 3 includes pedestal 31, and pedestal 31 is equipped with truncated cone-shaped skull 32, and so design adds the air in pump case 11
Free air space increases air mass flow.
Fig. 2, Fig. 3, Fig. 4 are seen again, and the impeller 6 includes wheel disc 61, axle sleeve 63 is equipped on wheel disc 61 and in wheel disc 61 1
Side and several blades 62 being uniformly provided on 63 lateral wall of axle sleeve, blade 62 is in herringbone cambered design, and between blade 62
