Abstract
The invention provides a pump with a cylinder chamber formed by a cooperation of inclined rotary pistons (cams), a separator plate and an annular cylinder. The inclined rotary pistons of the pump are driven to rotate by external forces, and thus fluid (liquid or gas) from a low place is conveyed to a high place by the pump or a low pressure (a normal pressure) is transformed into a high pressure by the pump. The pump of the invention has the advantages of high work efficiency and smooth operation.
Description
Technical field
The present invention relates to a kind of pump, belong to mechanical manufacturing field, this pump is under the effect of power outside, and fluid (liquid) is sent to eminence from lower, perhaps fluid (gas) is become a kind of device of high pressure by low pressure (normal pressure).
Background technique
What generally use at present is " centrifugal pump ", " reciprocating piston pump ", " rotor pump " (wherein rotor pump comprises: gear pump, screw pump, Roots pump, flexible blade pump, sliding vane pump, peristaltic pump) etc.Its major defect is that efficient is low, loss is big, application is narrow.
Summary of the invention
The technical problem that the present invention solves is to utilize inclined-plane piston, dividing plate, circular cylinder to match, and mechanical energy is transformed into the potential energy of fluid.But provide a kind of efficient, energy-conservation low-speed running, running steadily, accurate measurement, broad-spectrum fluid pump.
Description of drawings:
" Fig. 1 " is the general structure important plan of twin-tub fluid pump.
" Fig. 2---15 " be the working principle structure sketch of fluid pump.
Its critical piece and title: (1) low pressure (normal pressure) inlet; (2) high-pressure outlet; (3) dividing plate; (4) inclined-plane piston (cam); (5) axle; (6) annular cylinder; (7) main body; (8) body cover; (9) dividing plate spring; (10) top cover; (11) one-way cock.
" Figure 16 " is the external structure important plan of fluid pump.
Embodiment:
Working principle:
One, the fluid pump of no one-way valve
1, circle when being in position shown in (as Fig. 2) when inclined-plane piston dextrorotation, dividing plate glides along the inclined-plane under the effect of spring, the cylinder chamber volume of ingress begins to increase, the ingress produces negative pressure, and fluid is filled the inlet cylinder chamber that increases under atmospheric effect.Simultaneously, the cylinder chamber volume of outlet end begins to reduce, and fluid is discharged from outlet end.
2, when piston rotates to (Fig. 3) position by (Fig. 2), dividing plate slides into the mid point of inclined-plane piston under the streamline inclined-plane of piston (two inclined-planes are designed to 3 β=180 ° cosine line respectively).At this moment dividing plate is by all quickening the descending downward movement of all slowing down that becomes.The cylinder chamber volume of ingress continues to increase, and fluid continues to flow into from inlet.Simultaneously, the cylinder chamber of outlet end continues to reduce, and fluid is discharged from outlet end continuously.
3, rotate to (Fig. 4) position by (Fig. 3) when piston, dividing plate is down to minimum point.In the above process, the entering and discharging of fluid all is that the inclined-plane curve according to piston increases progressively, and then is rotated clockwise to (Fig. 5) position with peak rate of flow then.
4, when piston runs to (Fig. 5) position clockwise, piston has pivoted about 270 °.This moment, another inclined-plane began upwards jack-up dividing plate.Flow also begins to successively decrease with the inclined-plane curve.
5, piston remains in operation to (Fig. 6) (Fig. 7) position, and dividing plate is by inclined-plane jack-up, and flow is decremented to zero by maximum.During to (Fig. 7) position, entrance and exit all is closed.Remain in operation to (Fig. 2) position, finished the running of one-period, the circulation of beginning next cycle.
This pump generally is used for liquid (as water, oil pump etc.) and than resisting medium, perhaps the gas of low exhaust pressure (as blower etc.).
The fluid pump that two, one-way valve is arranged
1, shown in (Fig. 8), " fluid pump that one-way valve is arranged " compares " fluid pump of no one-way valve ", and entry and exit are designed smallerly, and locates to be provided with " one-way cock (11) " in " high-pressure outlet (2) ".
2, circle when being in shown in (Fig. 8) position when inclined-plane piston dextrorotation, one-way cock is in closed condition, prevents that pressurized gas from refluxing.
3, with " no one-way valve fluid pump " same principle, the inclined-plane piston rotates to (Fig. 9), (Figure 10) position, and when continuing to rotate to pact (Figure 11) position, the cylinder chamber volume-diminished of outlet end is to certain value, and air pressure also increases to certain value.When air pressure increases to when being slightly larger than outlet end air pressure, one-way cock is washed open, and at this moment beginning provides pressurized gas to outlet end.
4, piston remains in operation to (Figure 12), (Figure 13) position, and when piston operation arrived (Figure 14) position, the air inlet of one-period finished, and one-way cock begins to close.
5, piston remains in operation to (Figure 15), and entrance and exit all is closed.Piston remains in operation to (Fig. 8) position, finishes the running of one-period, the circulation of beginning next cycle.
This " fluid pump that one-way valve is arranged " generally is used for the medium that high-pressure pump or gas and liquid mix.
In order to reduce flowed fluctuation, can even numbers cylinder in parallel (180 ° of phase place 2 cylinders in parallel, 90 ° of phase place 4 cylinders in parallel, 60 ° of phase place 6 cylinders in parallel, the rest may be inferred).Cylinder number in parallel is many more, and flowed fluctuation is just more little.
Claims (5)
1. a pump utilizes inclined-plane piston, dividing plate to cooperate the cylinder chamber that forms with annular cylinder, under the drive of power, fluid (liquid or gas) is sent to eminence by lower outside, or is become a kind of device of high pressure by low pressure (normal pressure).It is characterized in that: external force drives inclined-plane piston rotation, and piston one end in inclined-plane produces low pressure, sucks fluid, and the other end then produces high pressure, discharges fluid.
2. pump according to claim 1 is characterized in that: inclined-plane piston likeness in form cam, two inclined-planes are designed to 180 ° of cosine lines (use polar coordinates) respectively.
