Abstract

Disclosed is a translational ring rotor pump. A vortex mechanical translational method is introduced to a rolling piston pump, and wear state of the end face is improved, thereby reducing wear and increasing efficiency. Except stability of output flow failing to reach a high rotational speed vortex liquid pump, advantages of easy processing and maintenance more facilitate popularization of the pump. Axially embedded flexile materials on the inner wall of a containing cavity form 'clearance' fit, and spacings of the flexible materials are temporarily used for hiding solid particles and increasing 'angle' of a fit area so as to help to reduce internal leakage and guarantee output pressure in low rotation speed.

Description

Translatory ring rotor pump

Technical field

This patent relates to the radial delivery type fluid machinery in the rotary fluid machinery, is the improvement of rolling piston pump.

Technical background

The leakage rate of gear pump end face accounts for 2/3 of the total leakage of pump, and there is uneven wear in this zone, is the structure that should improve that spells out in the Machine Design taboo.The clearance issues at this place affects the raising of pump efficiency always for a long time.Also there are identical problem in cam pump, rolling piston pump etc.

Scroll machine progressively is familiar with its outstanding performance.The moving spin-free circular movement of vortex promptly so-called " spin-free circular movement pattern " makes end wear even, reaches desirable gap after " break-in ".

Rolling piston pump and vortex pump are both eccentric wheel and drive, the above-mentioned advantage of the easiest absorption vortex pump.

It is simpler to design a kind of structure, and to keep the new pump of vortex pump advantage basically be necessary and feasible.

Summary of the invention

Translatory ring rotor pump is a translation mode of introducing scroll machine on the rolling piston pump, in columniform shell (1), the ring-shaped cylinder rotor (2) that easy processing is arranged, rotor is under eccentric wheel (13) drives, and the internal circular surfaces of assurance cylindrical outer surface and pump case remains and agrees with line; This is similar with the rolling piston pump structure, different is rotor translation under the control of anti-spin mechanism's translation ring (4), the end face that reaches ring equates with the relative moving speed of each point in the shell end cap, has avoided the appearance of uneven wear, can reach the effect of " break-in "; Accomplish rational internal leakage, help the raising in efficient and life-span; The traverse (8) of turnover sap cavity) section is " L " type, slides in the chute (7) of rotor rollaway nest (6) and pump case respectively in two ends.Machine parts than vortex liquid pump still less and is easy to make.Only on the steady degree of output, be inferior to high rotating speed eddy type liquid pump (ZL200410000564.1).

The traverse that section is " L " type can play the effect that keeps the rotor translation.In order to alleviate the wearing and tearing of traverse, can set up semicircle translation ring (4), the chute (13) of its slide block is relative with skateboards slot (6) on the end face of rotor, and two Vertical direction slide blocks slide in the chute (5) of end cap in addition.

The above can be used for compressor, vacuum pump, oil pump; Also can change a little and can make mixed defeated pump of liquid gas and water pump etc.Be used as the water pumping of the wind-force pump and done following change in structure:

The cavity volume inwall has a plurality of axial notches (16) except that the chute district; Axially inlay flexible material, flexible material (17) is not full of axial notch, leaves solid particle detention space (18), and flexible material slightly protrudes in the exocoel.

Description of drawings

Fig. 1 is the axial arrangement schematic representation of pump.

Fig. 2 is double pump misphase position and cross-sectional schematic radially.

Fig. 3 is the cavity volume schematic representation when carrying the liquid that contains solid particle.

Embodiment

Double pump misphase position connects the stability can improve output, as Fig. 1 and 2: the stator (1) with cylindrical cavity; In the cylindrical rotor (2) of an external diameter less than inner chamber twice throw of eccentric arranged, its end face and end cap surface of contact are ring; The ring rotor is under the driving of the eccentric wheel (13) on the power input shaft (11) and translation under the control of anti-spin partition ring mechanism; Anti-spin partition ring (4) is laid in zone in the ring, and its " X " slides in the groove (5) of slide block on end cap, and " Y " slides in the chute (3) of slide block at rotor; Traverse (8) one ends are in plane (7) the upward slip tangent and parallel with " X " glide direction with circle, and the other end slides in the chute (6) of rotor, plays the effect of isolation into and out of active chamber; Inlet opening (9) is offered on the stator of the moving limit position of isolating plate one side, medium enters admission chamber, when active chamber reaches maximum, manhole appendix is all by the ring-shaped cylinder natural enclosing, along with the mobile delivery outlet of ring-shaped cylinder is opened, liquid enters the ring-shaped cylinder inner axes district output at pump housing center again by the epitrochanterian hole of isolating plate one side (15).Pump can reverse work, and the flow direction of medium is opposite.

For being changed more steadily, output flow can spend the coaxial serial connection of pump of (360/N) with two (or N) phase differences 180, the output borrow stack of pump, and output tends to be steady, and flow increases; Easilier reach dynamic balancing.

The present invention is the translation method that the rolling piston pump is introduced scroll machine, and the state that has improved end wear makes that wearing and tearing reduce, efficient improves.Except that the too late high rotating speed vortex liquid pump of the stationarity of output flow, the benefit that is easy to process and keep in repair makes it be easier to promote.For being fit to use the pump that designs under the water pumping of the wind-force variable speed condition, the cavity volume inwall is axially inlayed flexible material and is formed " interference " and cooperate, and hides for solid particle and the delivery pressure when having increased " angle " of agreeing with the district and helping reducing internal leakage and ensure the slow-speed of revolution in the interval of flexible material temporarily.

The main feature of translatory ring rotor fluid machinery is that it is easy to manufacture. Cost is low, is easy to apply.

This patent has illustrated the pump structure principle take liquor pump as example. It all belongs to category and the protection domain of invention in the application of fluids mechanical aspects.
