Abstract
The utility model relates to a take volute pump of plane vortex gate, this gear pump is mainly by double shrouded wheel (1), open runner (2), import vortex gate (3), export vortex gate (4) the four bibliographic categories divides and forms, to import vortex gate (3) and install the import department at the open runner of volute pump (2), the exit in open runner (2) is installed to export vortex gate (4), the export liquid stream angle of import vortex gate (3) is unanimous with volute pump import fluid streamline orientation, the imported liquid stream angle of export vortex gate (4) is unanimous with volute pump export fluid streamline orientation. Compare with traditional volute pump, the utility model discloses mainly through installing the exit flow field that the plane vortex gate imported and exported at the pump improves the volute pump to energy loss greatly reduced is imported and exported to the runner of volute pump, and the efficiency of pump has obvious improvement, and the cavitation performance is obviously improved, and the volute pump operation is more steady.
Description
Technical field
The present invention relates to fluid machinery, be related specifically to a kind of peripheral pump with plane honeycomb.
Background technique
Peripheral pump (also claiming turbulence pump) is a kind of vane pump, by the active force of main rotary blade to liquid, in liquid moving direction, liquid transmits kinetic energy to realize carrying liquid with momentum, the feature of this pump is, high-lift, small flow, structure is simple, volume is little, there is the lift-flow curve and power versus flow curve that suddenly fall, gas-liquid delivery can be realized, peripheral pump is mainly used in chemical industry, carry high-lift in the industrial flows such as medicine, the acid of small flow, alkali and other effumability liquid that are corrosive, usually be also used in as fire water pump, boiler feed pump and general suction booster use, but the low pitting difference of its efficiency, and be not suitable for transfer of highly viscous liquid, therefore application area is narrow, popularization is poor.The present invention is based on CFX flow field simulation to analyze, find that the import and export fluid energy losses of the runner of peripheral pump is very large, and have the appearance of vortex and cavitation, therefore the invention provides a kind of design method improving peripheral pump runner import and export flow field, it is made to run more steady, cavitation performance is better, and efficiency improves obviously.
Summary of the invention
Because the import and export flow field of peripheral pump is disorderly, the problem that energy loss is larger, the invention provides a kind of design method improving peripheral pump import and export flow field, by importing and exporting at peripheral pump runner the exit flow field that mounting plane honeycomb improves peripheral pump, reduce the fluid energy losses that peripheral pump runner is imported and exported, and improve its cavitation performance.
Realizing the technological scheme that above-mentioned purpose adopts is:
The present invention is a kind of peripheral pump with plane honeycomb.This peripheral pump is primarily of double shrouded wheel (1), open type runner (2), inlet flow straightener (3), Exit flow straighteners (4) four part composition, inlet flow straightener (3) is arranged on the inlet of peripheral pump open type runner (2), Exit flow straighteners (4) is arranged on the outlet port of open type runner (2), the outlet flow angle of inlet flow straightener (3) is consistent with peripheral pump inlet fluid streamline direction, and the import flow angle of Exit flow straighteners (4) is consistent with peripheral pump outlet fluid grain direction.Compared with traditional peripheral pump, the present invention is owing to importing and exporting the rectified action of plane honeycomb, and the import and export flow field of peripheral pump is greatly improved, and the energy loss that pump is imported and exported reduces greatly, and cavitation performance improves, and the efficiency of pump is significantly improved.
The invention has the beneficial effects as follows: the efficiency of peripheral pump improves, and cavitation performance improves, and pump is imported and exported flow field and improved, and the life-span is longer, runs more reliable.
The present invention tries out through user, and reaction effect is good.
Accompanying drawing explanation
Fig. 1 is the peripheral pump structural representation of band plane honeycomb of the present invention.
In figure: 1. double shrouded wheel, 2. open type runner, 3. inlet flow straightener, 4. Exit flow straighteners.
Embodiment
Fig. 1 is the peripheral pump structural representation of band plane honeycomb, be made up of double shrouded wheel (1), open type runner (2), inlet flow straightener (3), Exit flow straighteners (4) four part, inlet flow straightener (3) is arranged on the inlet of peripheral pump open type runner (2), Exit flow straighteners (4) is arranged on the outlet port of open type runner (2), the outlet flow angle of inlet flow straightener (3) is consistent with peripheral pump inlet fluid streamline direction, and the import flow angle of Exit flow straighteners (4) is consistent with peripheral pump outlet fluid grain direction.
This peripheral pump improves the import and export flow field of peripheral pump mainly through the plane honeycomb being arranged on pump import and export, reduces the fluid energy losses that pump is imported and exported.
Claims (2)
1. the peripheral pump with plane honeycomb, this peripheral pump is primarily of double shrouded wheel (1), open type runner (2), inlet flow straightener (3), Exit flow straighteners (4) four part composition, its major character is: install inlet flow straightener (3), in outlet port installation outlet honeycomb (4) of open type runner (2) in the inlet of peripheral pump open type runner (2).
2. the peripheral pump of band plane honeycomb according to claim 1, it is characterized in that: the outlet flow angle of inlet flow straightener (3) is consistent with peripheral pump inlet fluid streamline direction, the import flow angle of Exit flow straighteners (4) is consistent with peripheral pump outlet fluid grain direction.
