Background technique

The axial--flow blading pump is widely used in the industrial and agricultural production, and Chinese patent CN2500841Y discloses a kind of applicable to the good positive displacement rotor infusion pump of turbid liquid pump drainage, handling property to containing solid phase particles on the basis of axial-flow pump.Characteristics are: comprise shell, interior cover, spacer, rotor and fin; In be sheathed in the shell of cylinder barrel shaped, form four axial chambers, the rotor that is provided with fin is positioned at cover, makes it to form four liquid zones.Compare with plain shaft streaming vane pump, under equal length and external diameter condition, its lift is higher, flow is bigger.The deficiency of its existence is that the spacer that is provided with between interior cover and rotor causes device not reverse; On the other hand, find under study for action, suitably adjust the mounting point of two end cap and, the rotor generation is rotatablely moved and the contrary running of implement device from former liquid outlet channel input high pressure liquid liquid.

Summary of the invention

The purpose of this utility model is: a kind of infusion pump that both can be used as is provided, can be used as a kind of rotary wing type liquid machine device of hydrodynamic mechanism again.

The utility model realizes that the concrete Technological improvement plan of above-mentioned purpose is as follows:

A kind of rotary wing type liquid machine device, comprise shell, interior cover, rotor, fin, front cover and rear end cover, shell is a cylinder barrel shaped, on its internal surface, uniform four boss vertically, in four interior boss of cover and shell cooperate and be located in the shell, make four axial cavitys of formation between shell and the interior cover, uniform through hole on the interior jacket wall, columniform rotor is positioned at cover, on the rotor, uniform four fins vertically; Front cover and rear end cover lay respectively at the two ends of rotor, and front and back ends covers and is evenly equipped with two apertures; It is characterized in that:

In described on the jacket wall, uniform four row through holes vertically, every row through hole respectively with shell and interior cover between a cavity forming corresponding; In on the cover madial wall, uniform the boss of two smooth transition vertically;

The a pair of cavity that forms between two apertures on the described front cover and shell and the interior cover is corresponding, and another that forms between two apertures on the rear end cover and shell and the interior cover is corresponding to cavity.

Useful technique effect of the present utility model is embodied in several aspects:

1, the utility model is when the low-pressure state operation, can be used as liquid conveying device uses, promptly can be used for agricultural production, water conservancy irrigation pump, also can be used for industrial and mining enterprise and city for, draining pump, engineering construction, sewage treatment and Geotechnical Engineering are with pump and various general water pump.

2, the utility model also can be used as liquid (gas) motivation tool.Compare with like products such as existing oil, coal and the exploitation of other usefull mineral, the downhole motor of exploring (drilling well) usefulness, helicoid hydraulic motor, turbine brills, it has four aspect advantage: A, big with bore unit length output torque, can be made into ultrashort, high pulling torque shaft bottom power unit; B, the same with the turbine brill can at high temperature turn round, at same bore, with the utility model length much shorter under the output torque; The working medium of C, conveying is liquid both, also gas; E, few because of making consumptive material is so manufacture cost is relatively low.

Embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated by embodiment.

This rotary wing type liquid machine device comprises shell 1, interior cover 2, rotor 5, fin 3, spring 4, front cover 6 and rear end cover 7, shell 1 is a cylinder barrel shaped, on its internal surface, uniform four boss vertically, in four interior boss of cover and shell cooperate and be located in the shell, make four axial cavitys of formation between shell and the interior cover, uniform through hole 12 on the interior jacket wall, columniform rotor 5 is positioned at cover, on the rotor, uniform four fins 3 vertically; Front cover 6 and rear end cover 7 lay respectively at the two ends of rotor 5, and front and back ends covers and is evenly equipped with two apertures.

Architecture advances is:

On the interior jacket wall, uniform four row through holes 12 vertically, every row through hole 12 respectively with shell and interior cover between a cavity forming corresponding; In on cover 2 madial walls, uniform the boss 8 of two smooth transition vertically;

During assembling, two relative cavitys that form between two apertures on the front cover 6 and shell and the interior cover are corresponding, form between two apertures on the rear end cover 7 and shell and the interior cover two two relative cavitys are corresponding in addition.

Behind the cover 2, promptly form four axial cavitys between shell 1 and the interior cover 2 in embedding in four boss of shell 1; In the curve bath mounting point that is provided with on the capping 8 of uniform four row through holes and front cover 6, rear end cover 7 on cover 2 walls, vertically make above-mentioned four cavitys become four passages, wherein 10, two exhalant canals 11 of two intake tunnels are seen Fig. 1.The boss 8 circular arc top spacings of the external diameter of rotor 5 and two sections symmetrical smooth transition of interior cover 2 inwalls from nominal size equate; Article four, the equidistant fin 3 that is provided with is pressed on the inwall of interior cover 2 by spring 4.

If the no external force of rotor 5 drive, then pressure equates between four passages, the fin both sides do not have pressure difference, and this device remains static.If power engine drives rotor by aspect shown in Figure 1 rotation, fin 3 will enter the liquid extruding of its moving direction front portion in the hyperbaric chamber 11 between shell 1 and the interior cover 2 by the moment of torsion of rotor; The liquid zone at fin 3 rear portions forms negative pressure owing to volume enlarges, and sucks liquid from low-pressure cavity 10; Rotor 5 whenever rotates a circle, and every fin is finished and extruded and suck each twice; The every pair of hyperbaric chamber and every pair of each supercharging of low-pressure cavity and suck twice; Along with rotor 5 continues rotation, pressure difference is increasing between the chamber that the two pairs of pressure does not wait, and the liquid in the hyperbaric chamber will back down check valve 9, continuously flow out high-pressure channel.Meanwhile, low pressure liquid also successively is inhaled into low-pressure channel.At this moment, this device enters the transfusion running state.

Front cover 6, rear end cover 7 respectively revolved turn 90 degrees installation, be that two cavitys 10 forming between two arc apertures and shell and the interior cover on the front cover 6 are corresponding, form between two apertures on the rear end cover 7 and shell and the interior cover two cavitys 11 are corresponding in addition, the high and low pressure chamber in this device with advance drip chamber and will replace.As remove check valve 9, with the hyperbaric chamber 10 of high pressure liquid stream (air-flow) input device, 3 of fins are pushed to low voltage side because of pressure at both sides does not wait from the high pressure side, thereby drive the rotor rotation; Liquid stream (air-flow) after releasing energy is discharged from low-pressure channel 11.As long as high pressure liquid stream (air-flow) is input device constantly, rotor 5 will ceaselessly rotate.At this moment, device enters liquid (gas) power power engine running state.
