Abstract
The invention relates to an efficient flow adjusting device for a compressor. The efficient flow adjusting device comprises an inlet flow adjusting guide blade, an air inlet channel and a rotating shaft; the inlet flow adjusting guide blade can be driven by the rotating shaft to rotate, so that the air inlet flow direction and the air inlet flow area are changed, and the effect of adjusting the flow is achieved; in order to achieve the aim that the inlet flow adjusting guide blade rotates around the rotating shaft, the top of the blade cannot be completely coincident with the air inlet channel, a certain gap needs to be reserved at the top of the blade, a part at the position, above the position where the inlet flow adjusting guide blade (1) is located, of the air inlet channel (2) is excavated out according to an arc curve formed by rotating the blade by a circle around the rotating shaft, the part of the gap of the inlet flow adjusting guide blade is wrapped, and influences of the gap on an air inlet channel flow field are minimum.
Description
Technical field
The invention belongs to compressor field, be related specifically to compressor efficient stream quantity regulating device.
Background technique
Compressor climate impact in running needs the flow of frequent adjustments of gas, method by installing air-intake guide vane additional in import in a lot of situation controls flow, but due to designing technique relatively backward, the ability of current air-intake guide vane adjust flux is inadequate, cause emptying because tolerance is superfluous in the winter time slatterning, the tolerance up to 30% will be wasted time maximum, cause the waste of the energy, current international most advanced level at most only needs the tolerance of emptying 15%, therefore the design of entry guide vane is improved, developing efficient stream quantity regulating device is that the current compressor industry of China is badly in need of one of key technology solved, for raising China compressor design technology, enterprise competitive ability has great importance, energy-saving and emission-reduction are of great immediate significance simultaneously.
When centrifugal compressor entry guide vane regulates, stator can be rotated a certain angle, such air-flow along the channel flow angled with axial admission direction, and will reach prewhirling and throttle effect of expection.Due to the structural type of inlet passage and blade, make stator when rotating to an angle, its top and pipeline can not fit like a glove, and leave gap, wherein a part of air-flow (accounting for about 8% of total tolerance) can along Clearance Flow, and this part air-flow not only can not get effective adjustment, and main flow is impacted, cause flow losses, the power consumption of compressor is strengthened, wastes energy.The existence of clearance between guide vanes can cause stator flow losses to increase, and stator produces the ability reduction that air-flow is prewhirled, the regulating working conditions range shorter of compressor stage.The established angle of stator is larger, and the impact of Clearance Flow is also more serious.Therefore, the efficiency of entry guide vane can be improved by improving foil nozzle, thus improve the off design performance of centrifugal compressor.
Summary of the invention
The present invention provides a kind of centrifugal compressor efficient stream quantity regulating device, its objective is by changing stator position inlet passage structure, its blade tip clearance is diminished, expand the scope of stator Flow-rate adjustment, reduce the flow losses of stator flow channel fluid, reach the object of province's merit, thus reduce the utilization of the energy.
Technological scheme of the present invention is as follows: compressor efficient stream quantity regulating device, comprise inlet flow rate and regulate guide vane, gas-entered passageway, rotatingshaft, inlet flow rate regulates guide vane to be rotated by rotatingshaft drive, thus change direction and the area of air inlet incoming flow, and then reach the effect of Flow-rate adjustment, inlet flow rate regulates guide vane in order to reach the object rotating around it axle and rotate, its leaf top place can not fit like a glove with gas-entered passageway, certain interval to be left at its leaf top place, regulate the top gas-entered passageway 2 of guide vane 1 present position to rotate around it the rotate a circle shape of formed circular arc camber of axle by stator by inlet flow rate and hollow out a part, it is made to be wrapped up by gap portion of stator, the impact of gap on gas-entered passageway flow field is made to reach minimum.
The change that effect of the present invention and benefit are mainly reflected in gas-entered passageway can not affect stator rotating freely around its rotating shaft, although leaf top place and gas-entered passageway still have gap to exist, but substantially reduce the impact on inlet flow field by improved gap, air-flow is made to obtain more effective adjustment, therefore, the present invention not only increases the adjusting function of entry guide vane to compressor, flow adjustment range is expanded, also reduce the flow losses of the inlet air flow that the existence due to gap causes, improve the adjustment efficiency of entry guide vane, thus improve the off design performance of centrifugal compressor, make because tolerance is superfluous that emptying gas flow greatly reduces, reach the object of energy saving.

Accompanying drawing 1 is sectional view of the present invention.
In figure: 1, inlet flow rate regulates guide vane; 2, gas-entered passageway; 3, rotatingshaft.
Embodiment
Compressor efficient stream quantity regulating device, comprise inlet flow rate and regulate guide vane 1, gas-entered passageway 2, rotatingshaft 3, inlet flow rate adjustment guide vane 1 drives by rotatingshaft 3 and is rotated, regulated by inlet flow rate the top gas-entered passageway 2 of guide vane 1 present position to rotate around it the rotate a circle shape of formed circular arc camber of axle by stator and hollow out a part, make it be wrapped up by gap portion of stator, make the impact of gap on gas-entered passageway flow field reach minimum.
