The utility model can work normally and output higher pressure heads even under the condition of very low rotary speed of the rotor, and therefore, the utility model has the advantages of low energy consumption and higher pump efficiency.
Description
The utility model relates to the blade of a kind of rotating vane pump, particularly a kind of rotating vane pump.
What Chinese coal publishing house in February, 1984 front page was published is translated, is disclosed a kind of rotating vane pump in former " pump and the application thereof " book of growing U.S. work of day this Kaji by Sun Shangyong.The pump housing of this rotating vane pump has fluid input and fluid output, cylindrical cavity is arranged in the pump housing, a cylindrical rotor is arranged in the inner chamber of the pump housing, the cylinder axis of the cylinder axis of rotor and pump housing inner chamber is eccentric to be installed, be that parallel axes is not on same axis, groove is radially arranged on the circumference of rotor, be inserted with blade in the groove, blade can be reposefully into and out of slip in epitrochanterian groove, the cylindrical cavity of the pump housing is being crowded around the blade of rotor, two ends at the pump housing have end plate respectively, maintain optimum gap between the pump housing, rotor, blade and the end plate and assemble up.When rotor rotates, because of rotation produces centrifugal force, make blade make circular movement by outwards skidding off the internal chamber wall that is tight against at stator in the groove of rotor, adjacent vanes sucks fluid from fluid input, from fluid output fluid is extruded.The blade of this rotating vane pump is to depend on centrifugal force to be tight against at the internal chamber wall of the pump housing, and rotor has only when rotated and can produce effective centrifugal force under the rotating speed condition with higher, under the lower situation of rotating speed, can not produce effective centrifugal force, so when rotor speed is low, defeated pressure head can be very low, even cisco unity malfunction; This in addition rotating vane pump is when work, and the internal chamber wall of the blade and the pump housing is sliding friction, so the efficient of pump is low, energy consumption is high.
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of rotating vane pump that energy consumption is low, efficient is high that still can export higher pressure head under the slow-speed of revolution.
The utility model is realized with the following method.
This rotating vane pump has the pump housing, the pump housing has fluid input and fluid output, cylindrical cavity is arranged in the pump housing, in the inner chamber of the pump housing cylindrical rotor is arranged, the cylinder axis of the cylinder axis of rotor and pump housing inner chamber is parallel to each other but not on same axis, be eccentric the installation, the square groove that is evenly distributed in even number at rotor, be inserted with blade in the square groove, blade can advance in epitrochanterian groove reposefully, go out to slide, between two square grooves on the rotor on the same diameter through hole is arranged, two blades on the same diameter outer the bottom half relative hole is arranged, be connected with the rigidity straight-bar by above-mentioned through hole between half hole, be to link to each other at the bottom of the blade in two square grooves on two ends and the same diameter of rigidity straight-bar, there is the rectangular ring that is enclosed within on the rotor shaft in rigidity straight-bar stage casing, at the top of blade axial cylindrical rollers is arranged, when the rigidity straight-bar with after two blades link to each other, the distance between the roller outward edge of rigidity straight-bar two ends vane tip and the equal diameters of pump housing inner chamber, the cylindrical cavity of the pump housing is being crowded around the blade of rotor, two ends at the pump housing have end plate, the pump housing respectively, rotor, maintain optimum gap between blade and the end plate and assemble up.
During use, the blade that the rotor rotation drives in the groove is made circular movement, owing between the two ends blade of same diameter the rigidity straight-bar is arranged, the distance between the roller outward edge of two vane tips and the equal diameters of pump housing inner chamber circumference, so blade is to be tight against on the peripheral wall of pump housing inner chamber, again because there is the rectangular ring that is enclosed within on the rotor shaft in the stage casing of straight-bar, so although rotor and pump housing inner chamber are eccentric the installations, when rotor rotates, can drive blade makes circular movement and advances in square groove around the inner chamber of the pump housing, go out motion, blade remains at blade when the pump housing is made circular movement and is tight against on pump housing internal chamber wall, owing to during the rotor rotation, can make the rotating vane pump proper functioning so blade remains to push against on pump housing internal chamber wall.
Between two blades on the same diameter of the present utility model the rigidity straight-bar is arranged, can guarantee that blade is tight against all the time on pump housing internal chamber wall, even also can proper functioning and exportable higher pressure head under the very low situation of the rotating speed of rotor, in addition, the front end of blade is a roller, when blade was made circular movement, blade and pump housing internal chamber wall were not sliding frictions, but rolling friction.So energy consumption is low, pump efficiency is higher.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the main half sectional view of rotating vane pump,
Fig. 2 is the A-A view of Fig. 1,
Fig. 3 is two blade and the schematic perspective view of straight-bar therebetween on the same diameter.
Fig. 1, Fig. 2, among Fig. 3, rotating vane pump has the pump housing 1, the pump housing 1 has fluid input 12 and fluid output 13, cylindrical cavity 14 is arranged in the pump housing 1, in the inner chamber 14 of the pump housing 1 cylindrical rotor 2 is arranged, the cylinder axis 21 of rotor 2 and the cylinder axis of pump housing inner chamber 11 are parallel to each other but not on same axis, be eccentric the installation, rotor 2 be evenly distributed in six square grooves 22, be inserted with blade 23 in the square groove 22, blade 23 can advance in epitrochanterian groove 22 reposefully, go out to slide, two end faces of rotor 2 have respectively and the concentric circular groove 24 of end face circle, through hole 25 is arranged at the bottom of two square grooves 22 on circular groove 24 and the same diameter, there is half relative hole 26 at the place, two ends of the bottom outside two blades 23 on the same diameter, 26 in two and half holes are connected with rigidity straight-bar 27 by through hole 25, between rigidity straight-bar 27 two ends and the blade 23 compression helical spring 231 is arranged respectively, there is the rectangular ring 28 on the axle that is enclosed within rotor 2 in the stage casing of rigidity straight-bar 27, rectangular ring 28 is in circular groove 24, at the top of blade 23 axial cylindrical rollers 29 is arranged, when rigidity straight-bar 27 with after blade 23 links to each other, the distance between roller 29 outward edges at two blade 23 tops and the equal diameters of pump housing inner chamber 14, the cylindrical cavity 14 of the pump housing 1 is being crowded around the blade 23 of rotor, two ends at the pump housing 1 have end plate 3 respectively, the pump housing 1, rotor 2, maintain optimum gap between blade 23 and the end plate 3 and assemble up.
