Abstract

The utility model composed of a base, a motor and an air pump, have two molds such as a horizontal type and an upright type. The air pump is stacked with at least two layers of centrifugal generators. Any other mechanical contact does not exist in a container except for a bearing. A movable impeller and a guiding impeller are distributed on a spindle in turns. The movable impeller is positioned and extruded by an impeller spacer sleeve, and the guiding impeller is positioned and extruded by a rabbet of the container. The movable impeller moves following the spindle during operation, and the guiding impeller is immobilized. The movable impeller and the guiding impeller comprise circular double-layer cover plates, the interlayers of the double-layer cover plates are uniformly distributed with at least six centrifugal cambered blades, and the cover plates are locked by the symmetrical clamps of the cambered blades.

Description

Stacked air pump

The utility model relates to a kind of stacked air pump, is a kind of low-pressure gas source generator.

Stacked air pump is a kind of low-pressure gas source generator, except that bearing, there is not the mechanicalness contact in the casing, compare with reciprocating pump, scraping blade pump, water ring pump, vacuum pump, air compressor in the market, have and do not have that oil is anhydrous, the few volume of electricity consumption is little, in light weight, noise is low, simple in structure, stable gas pressure, advantage such as easy to maintenance.Be mainly used in industries such as printing, plating, Plastic Welding, environmental protection, source of the gas conveying, chemical industry, cigarette, aquaculture, packing, weaving, video display, glassware.

The purpose of this utility model is to be to provide a kind of cover such as oil and water seperator, valuator, pipeline that saves to filter gauge device, and reduces the air pump of power consumption.

The utility model is by base, the motor air pump is formed, can be divided into horizontal, vertical two kinds of moulding, air pump has two at least the leafing core type is generator laminated and forms, except that bearing, there is not other any mechanicalness contact in the case, the movable vane wheel, guide vane wheel is distributed on the main shaft in turn, the movable vane wheel is by impeller spacer extruding location, guide vane wheel is by casing seam extruding location, and main shaft is fixed on protecgulum, on the bonnet, protecgulum and bonnet and casing merge, lock by pump housing lock nut again, fan is fixed on the main shaft, is assemblied in the bonnet outside, during work, the movable vane wheel moves with main shaft, and guide vane wheel then maintains static.Moving guide vane wheel comprises garden shape double-layer cover plate, is evenly distributed with at least six centrifugal sigmoid blades in the interlayer of double-layer cover plate, and cover plate is then locked by the dop of curved vane symmetry.

Be described in detail operation principles of the present utility model below in conjunction with drawings and Examples:

Figure 11 is the plan view of Figure 10;

Figure 12 is movable vane wheel, guide vane wheel curved vane plan view;

Figure 13 is movable vane wheel, guide vane wheel curved vane plan view.

Among the figure: 1 base; 2 motors; 3 protective housings; 4 driving belts; 5 bonnets; 6 air outlets; 7 pump housing lock nut; 8 fans; 9 imports; 10 main shafts; 11 movable vanes wheel; 12 guide vane wheels; 13,14 direct press type lubricating cups; 15 casing seams; 16 labyrinth seal figure; 17 curved vane and movable vane wheel, guide vane wheel doubling plate locking aperture; The import of 18 movable vanes wheel; The outlet of 19 movable vanes wheel; 20 protecgulums; 21 guide vane wheel imports; The outlet of 22 guide vane wheels; 23 casings; 24 curved vane dops; 25 impeller spacers.

Fig. 1 Fig. 2 Fig. 3 Fig. 4 is a horizontal type shaping, and Fig. 1 Fig. 2 outlet is arranged on the bonnet upper end, and Fig. 3 Fig. 4 is another embodiment, and its outlet is arranged in the middle of the bonnet.As seen from Figure 5 when air pump moves, extraneous source of the gas enters casing by intake grill 9 and enters the movable vane wheel import of first working room, because the source of the gas that runs up of movable vane wheel enters back continuous air-out below the centrifugal action of curved vane, enter the movable vane wheel import of second working room through guide vane wheel (Fig. 9) import 21-outlet 22, source of the gas is located output by last working room after reaching designing requirement through moving repeatedly to the air outlet like this, and gained source of the gas air pressure intensity is big, good stability.

Movable vane wheel 11, guide vane wheel 12 doubling plates and curved vane are stamping part, and material is an aluminum alloy, and part is even, and proportion is little.Doubling plate locking aperture 17 and curved vane dop processing request height, arrange accurately that in order in the assembling of impeller, the cover plate of earlier curved vane being packed into makes the curved vane dop insert the cover plate locking aperture, refills another cover plate, after dop riveted over and locked impeller.During the inner assembling of air pump, in proper order: bonnet put main shaft-labyrinth seal Figure 16-movable vane wheel 11-impeller spacer 25-guide vane wheel 12-casing 23-movable vane wheel 11-...-guide vane wheel 12-movable vane wheel 11-the locking spacer-protecgulum 20-locking pump housing lock nut.After install transmission device because air pump runs up, bearing produces huge energy, so the utility model has designed a radiation fan (Figure 10) between belt pulley and bonnet, can prolong bearing working life.

Claims

1, a kind of stacked air pump, form by base, motor, air pump, can be designed to horizontally or vertical, it is characterized in that having two at least by air pump the leafing core type is generator laminated forming, movable vane wheel, guide vane wheel are distributed on the main shaft in turn, the movable vane wheel is by impeller spacer extruding location, and guide vane wheel is by casing seam extruding location, and main shaft is fixed on the front and rear covers, protecgulum and bonnet and casing merge, by the locking of pump housing lock nut, fan is fixed on the main shaft again, is assemblied in the bonnet outside.
