Description

Moving plate rotator type high-pressure service pump

The utility model relates to a kind of moving plate rotator type high-pressure service pump, is the rotary-piston variable displacement pump that is used for liquid, gas.

Common fluid conveying machine comprises that reciprocating pump, centrifugal pump, gear pump etc. exist discharge pressure little, efficient is lower, shortcomings such as structure and manufacturing process complexity, rotary piston pump and above all kinds of pump are relatively, though designs simplification, efficient increases, but existing sliding vane rotary piston pump exists the sealing of slide plate and cylinder body poor, bear that pressure is difficult to further improve between topic.

The purpose of this utility model provides a kind of simple in structure, and good seal performance can be born high pressure, efficient height, the moving plate rotator type high-pressure service pump that gas, liquid medium all can be suitable for.

The utility model moving plate rotator type high-pressure service pump is provided with circle tube cylinder, two end caps at cylinder body two ends are respectively equipped with fluid inlet and outlet, be provided with the rotor tangent in the cylinder with inboard wall of cylinder block, rotor is equipped with an arcuated fin piece at least, one end of this arcuated fin piece is to be fixed on epitrochanterian pivot point, and the other end is the movable end that rotates around this fulcrum.When fin with rotor in cylinder during high speed rotating, the movable end of fin is close to the inside wall of cylinder all the time, and makes the supercharging of cylinder inner fluid and from the outlet output of cylinder.In the rotor high-speed rotary course, fluid from the end import input of cylinder body, is exported from the outlet of the other end continuously.Fin also can be provided with two or more, is provided with in the rotor equal intervals, and efficient is higher.For reducing rotor end-face frictional force, and improve the end face seal performance, can lay several filler rod grooves on the Transverse plane of two ends of rotor, be provided with filler rod in the groove, bottom land is equipped with the reed of contact filler rod, and the face that filler rod is positioned at notch is convex globoidal.Rotor contacts with cylinder body and end cap with the cambered surface of each filler rod, thereby end-face friction is reduced, and reed makes filler rod be tight against cylinder end caps, the end seal raising.For further improving the sealability between mobile wing and the inboard wall of cylinder block, circle tube cylinder of the present utility model can be made up of outer cylinder body and inner barrel, two end cap only links to each other with outer cylinder body, and inner barrel can rotate with respect to outer cylinder body, and the plurality of sections roller is housed on the surface of contact of urceolus and inner core.When rotor high-speed rotated, arcuated fin piece was close to inner barrel, and inner barrel is produced tangential force, rotated together thereby drive inner core.Further stifled exhausted leakage of this programme improved sealing, reduces the friction of fin.The utility model also comprises multi-cylinder series connection, and each cylinder rotor coaxial links to each other, last as in fact the outlet of cylinder join with the import of back one cylinder, the continuous level of delivery pressure is improved.

In sum, the utility model moving plate rotator type high-pressure service pump has adopted rotor and arcuated fin piece to realize transfiguration supercharging to the cylinder inner fluid, reaches the purpose of conveyance fluid.This pump can carry out the multi-cylinder series connection as required, thereby reaches higher pressure, and liquid and gas medium all are suitable for.During this pump high speed rotating, arcuated fin piece is subjected to the radial pressure of centrifugal force and cylinder inner fluid, make the end cambered surface press inboard wall of cylinder block, thereby sealability is good.Compare with existing all kinds of pumps, this pump structure and manufacturing process are simple, delivery pressure height and high working efficiency.

Below in conjunction with description of drawings example structure of the present utility model.

Fig. 1 is the external form view of this moving plate rotator type high-pressure service pump.

Fig. 2 is the A-A sectional drawing.

Fig. 3 is that the B of outer cylinder body among Fig. 2 is to unfolded drawing.

Fig. 4 is the end-face structure schematic representation of two ends of rotor.

Fig. 5 is the C-C sectional drawing of Fig. 4.

Fig. 1 represents that cylinder body 2 two ends are provided with end cap 1, and two end cap is respectively equipped with fluid inlet opening 3 and delivery outlet 6, and rotating shaft 4 is central shafts of cylinder internal rotor 5, and it makes rotor rotation (rotor structure is seen Fig. 2) by motor driving.

Among Fig. 2 embodiment, cylinder body 2 is made up of outer cylinder body 2-2 and inner barrel 2-1, and a plurality of rollers 8 are housed on the surface of contact of outer cylinder body and inner barrel, and it makes, and frictional force reduces between the inner/outer tube.The form that this roller 8 is short columns is distributed on the inwall of outer cylinder body, and Fig. 3 represents that the inwall of outer cylinder body launches view, and visible a plurality of short rollers 8 are distributed on the outer cylinder body 2-2 among the figure.See Fig. 2 embodiment, rotor 5 is tangent with the inwall of the inner core 2-1 of cylinder body, rotor be provided with at interval 180 ° two arcuated fin pieces 7 and 7 ', an end of fin is fixed on the rotor 5 by axle sleeve 12, forms pivot point.The fluid inlet opening on Fig. 1 right end cap is located in label 3 expressions, and label 6 is fluid outlets of being located on Fig. 1 end cap left side 1.When rotating shaft 4 during, rotor 5 and fin 7,7 ' in the direction of arrows high speed rotating by motor driving, simultaneously, fin 7,7 ' movable end open to the inwall direction of inner barrel 2-1 because of centrifugal action.Along with the rotation of rotor, the volume of fin one side J diminishes gradually in the cylinder, and the hydrodynamic pressure in the J increases, and acts on inner barrel by the cambered surface of fin 7, drives inner barrel and together rotates, and this moment, fin and inner barrel seemingly were integral.Along with the rotation of rotor, when J district inner fluid is pressurized to certain value, promptly to exporting from outlet.During Fig. 2 state, fluid is from the 3 input J districts that enter the mouth, and fin 7 pressurizes to the fluid in J district, the fin 7 ' fluid in the J ' district is exported from exporting 6.Under the rotor high-speed rotation, the input of this pump, pressurization and output procedure are carried out continuously.

Fig. 4 represents the end-face structure of rotor 5, radial alignment among the figure and camber line represent to be distributed in groove straight trough and the curve bath 9 on the rotor end-face, and filler rod 11 (see figure 5)s are housed in the groove, during the rotor rotation, its end contacts with the end cap 1 of cylinder body with filler rod 11, thereby and end cap between frictional force reduce greatly.In the visible groove of Fig. 5 reed 10 is housed, reed makes filler rod contact end cap all the time to notch direction contact filler rod 11, keeps good sealing state.

Fig. 6 represents the embodiment of the high formula pump of this rotator type by 2 series connection of three cylinder bodies, and the rotor in each cylinder is with 4 coaxial linking to each other of axle, and the outlet of a last cylinder body links to each other with the inlet of next cylinder.Take out body or liquid from 3 inputs of elementary inlet, after multistage pressurization, export by final stage outlet 6.
