Description

Centrifugal bulging pressure fan is imported and exported the stator controlling device
Technical field
The utility model relates to centrifugal bulging pressure fan, relates in particular to a kind of centrifugal bulging pressure fan and imports and exports the stator controlling device.
Background technique
Along with developing rapidly of The modern industry, centrifugal bulging pressure fan more and more is used widely in fields such as oil, chemical industry, and is simultaneously, also more and more higher to its requirement.All advocate energetically under the overall situation of low-carbon economy in the whole world, the user wishes to obtain energy-efficient machine.
Existing centrifugal bulging pressure fan can both guarantee high efficiency greatly on its design conditions point, but owing to operating mode in the actual using process is comparatively complicated, the drum pressure fan is difficult to remain on the design conditions point for a long time.When operating point departed from, if without effective adjusting, efficient will reduce rapidly, and is difficult to guarantee reliable operation.
Existing bulging pressure fan is general to adopt single import or export adjusting to adjust accordingly.Rotating entry guide vane modulability in the inlet adjusting, Economy are good, and owing to regulate and gas is produced prewhirl, when when increasing compressor flowrate, can adopt negative prewhirling; When reducing drum pressure fan flow, can just adopt and prewhirl, but adopt this kind method to regulate, because working flow is different from design discharge, just increased the loss of fixed elements such as Diffuser, and its efficient is reduced.Single outlet regulating, pass through adjustable vane, can change how much angles of diffuser intake, performance curve is significantly moved to the small flow district, and the surge flow is greatly reduced, thereby can be good at satisfying the operating mode of changes in flow rate, but this kind regulating method is to changing bulging pressure fan outlet pressure poor effect.
The model utility content
The purpose of this utility model is to provide a kind of centrifugal bulging pressure fan to import and export the stator controlling device, regulates when this device can be realized this centrifugal bulging pressure fan import, exit guide blade, to satisfy wide operating mode scope and high efficiency requirement.
The purpose of this utility model is achieved in that a kind of centrifugal bulging pressure fan import and export stator controlling device, it comprises the exit guide blade that is connected with the plate shell, and the entry guide vane that is connected with shell, it is characterized in that: it also comprises crank, drives circle, kinematic link, and bevel gear and gear disk; Described exit guide blade is connected with described crank, and this crank is connected with described driving circle, and this drives circle and is connected with described kinematic link; Described entry guide vane and described bevel gear are connected as a single entity, this bevel gear and gear disk engagement.
Above-mentioned entry guide vane is connected as a single entity by key and described bevel gear; The said gear dish is connected with the import pull bar, by being connected of import pull bar and outside final controlling element, can making outside final controlling element drive pull bar and move, thereby drive the rotation of whole gear disk.
Above-mentioned crank passes above-mentioned plate shell, the one end connects above-mentioned stator, the other end connects above-mentioned driving circle, so just can be by adjusting to the driving circle, and then the adjusting of realization stator, in order to changing diffuser exit air-flow angle, thereby avoid appearing at the too fast shortcoming of decrease in efficiency under the variable working condition.
Above-mentioned stator is connected with described crank one end by screw, above-mentioned driving circle is connected with the described crank the other end by connecting pin, this means of fixation is simple and convenient, connect firm, and,, simultaneously crank is connected by connecting pin with stator the rotation angle of crank and stator is consistent by the connection of screw, so that can relatively rotate between this pin and the crank, and then reach the purpose of adjusting vane.
Above-mentioned driving circle is provided with attachment hole, and this attachment hole is connected with kinematic link, and then is connected with outside final controlling element by kinematic link, realizes that outside final controlling element drives kinematic link and rotates, and then drives the rotation that drives circle.
The setting of above-mentioned stator by the respective numbers crank, its all with drive circle and be connected, turn round when realizing a plurality of stator, can accurately guarantee stator conformity rotatably in the adjustment process, thereby guarantee the uniformity of air-flow conversion, its using effect the best.
The utlity model has following beneficial effect:
Centrifugal bulging pressure fan in the utility model, when the import and export stator is united adjusting, well with both advantages together, entry guide vane is regulated pressure and the flow that can adjust bulging pressure fan efficiently, good energy saving property, effectively improved the efficient of unit, and the adjustable Diffuser of exit guide blade, the variation of adaptation flow that can wide range, regulation range is wide, because regulating, stator can change the diffuser intake geometric angle, thereby avoided entry guide vane to regulate owing to the different losses that increase of flow, bulging pressure fan can efficiently be moved all the time, and its compact structure, avoided taking in the axial direction bigger space, reduced the volume of bulging pressure fan, beneficial effect is remarkable.In addition, adjustable vane is adopted in its Centrufugal compressor impeller outlet in this device, the size that had both kept vaned diffuser is little, the high advantage of efficient under the design conditions again because blade angle is adjustable, and has changed diffuser exit air-flow angle, and the identical setting by some stators, guarantee the uniformity of air-flow conversion, thereby avoided appearing at the too fast shortcoming of Use Limitation rate decline under the variable working condition, realized the accurate adjusting of air pressure.
