Abstract

The invention relates to a device which uses for stir, pressure boost, and compression in varieties of fluids included liquid and gas. Its character is that the curved surface die cavity, in which there is a rotor, locate in the die cavity in which there are outer and inner curved surface, and the suction chamber and extruding chamber locate in the connect of them; The both sides of axial direction of the die cavity have match discharge orifice to connect with the suction chamber and extruding chamber; The rotation direction of rotor distribute uniformly n slots in which is located piston; The circumferential outside surface and inside surface of rotor is connected with the outer and inner curved surface of the curved surface each other; The side of the two terminal of radial direction of piston activity closure is connected with the outer and inner curved surface. The advantages are simple structure, light pulsation, low buzz, high efficient bulk, widely versatility.

Description

A kind of positive displacement compressor pump

One, technical field: the present invention relates to a kind of equipment that is used for the pumping of various fluids (comprising liquids and gases), supercharging and compression.

Two, background technique: at present, domestic and international normally used positive displacement compressor and pump mainly contain following several: 1, piston compressor or plunger pump, and this kind device structure complexity, pulsation, noise are bigger; 2, screw compressor or screw pump, its axial dimension is longer, the manufacturing difficulty; 3, scroll compressor, eddy type pump, the manufacturing difficulty, compression ratio is less; 4, gear pump, noise is big, and working life is short; 5, vane pump, easy to wear, the low speed starting capability is relatively poor.

Three, summary of the invention:

1, goal of the invention: the invention provides a kind of positive displacement compressor pump, its purpose be to provide a kind of simple in structure, pulsation is little, noise is low, volumetric efficiency is high, manufacturing is easy, versatility widely fluid pump, the equipment of supercharging, compression.

2, technological scheme: the present invention is achieved through the following technical solutions:

Be provided with curve-surface cavity in the die cavity body, create in the die cavity body and become to have positive camber, negative camber, rotor places in the curve-surface cavity, and the die cavity body communicates with curve-surface cavity suction chamber, delivery chamber; Described die cavity axon is provided with assignment hole that communicates with suction chamber and the assignment hole that communicates with delivery chamber to both sides; The circumferencial direction of rotor is evenly distributed with n slotted eye (n=1,2,3 ...), motion stops is configured in the slotted eye; The circumferential outer surface of rotor and circumferential inner surface are tangent with the positive camber and the negative camber of curve-surface cavity respectively; Motion stops radially both ends of the surface and positive camber and negative camber is tangent.

Described motion stops is solids such as hexahedron, cylindrical body.

Form M separate chamber by combination back between die cavity body, rotor and the motion stops,

M＝2(2π/ω)，(0＜ω≤2π)。

Motion stops 4 in the slotted eye 5 is that a plurality of rollers constitute.

3, advantage and effect: by enforcement of the present invention, can solve problem proposed by the invention well, this equipment is not only simple in structure, pulse little, noise is low, volumetric efficiency is high, manufacturing is easy, be a kind of versatility widely fluid pump, the equipment of supercharging, compression.

Accompanying drawing 6 is motion stops of the present invention and rotor slotted eye fit form schematic representation.

Five, embodiment:

As shown in the figure, the present invention contains: die cavity body 12 is disposed at the rotor 2 in the die cavity body 12, motion stops 4.Create in the described die cavity body 12 and become to have curve-surface cavity III, positive camber 1, negative camber 10, the suction chamber 6 that communicates with curve-surface cavity III, suction chamber 9 (diagram dashed region), the delivery chamber 3 that communicates with curve-surface cavity III, delivery chamber 8; Described die cavity body 12 axial both sides are provided with the assignment hole 6 ', 9 ' that communicates with suction chamber, the assignment hole 3 ', 8 ' that communicates with delivery chamber.Described rotor 2 places in the curve-surface cavity III, rotates around center O.An even distribution n slotted eye 5 on the circumference of rotor 2, (n=1,2,3 ...).Described motion stops 4 is configured in the slotted eye 5 of rotor 2, radially do periodically to-and-fro motion along slotted eye 5, and with rotor 20 rotation around the center, it extends radially out length and increases to maximum H gradually by 0, be decreased to 0 cyclically-varying again gradually by maximum H, the compound motion that makes motion stops 4 be done with respect to die cavity body 12 has been created into M separate chamber.M=2 π/ω, 0＜ω≤2 π, the angle that ω-motion stops is rotated around center O with rotor.Be illustrated as 2 airtight separate chamber I, II.Described rotor 2 circumferential outer surface A and circumferential inner surface B respectively with positive camber 1 and 10 tangent cooperations of negative camber of curve-surface cavity III, form 2 airtight separate chamber I, II.

Described motion stops 4 is rotated around center O with rotor 2, radially does the periodicity to-and-fro motion along slotted eye 5 simultaneously, its radially two end faces all the time with positive camber 1, negative camber 10 tangent slip or the rollings of curve-surface cavity III.Described motion stops 4 its structure characteristics can be six solids, can be cylindrical bodys etc., see Fig. 4,5.When center O was rotated, the swept volume of separate chamber I, II suction side was changed from small to big gradually by direction as shown for described rotor 2 and motion stops 4, and fluid is inhaled into separate chamber I, II by suction port 11 through suction chamber 6, suction chamber 9.Simultaneously separate chamber I, the II swept volume that extrudes end is when beginning greatly to diminish gradually, and fluid is discharged fluid through exporting 7 by delivery chamber 3, delivery chamber 8, realizes working procedure.

In accompanying drawing 6, the motion stops 4 in the slotted eye 5 can constitute for a plurality of rollers, shown in the figure is two, and the motion stops 4 that is formed by a plurality of rollers forms rolling.
