Scroll type fluid machinery
Technical field
What the present invention relates to is scrollwork (revolving) fluid machinery, and it can be used as compressor, vacuum pump, decompressor or the like.
Technical background
Adopt parallelogram anti-rotation mechanism scroll type fluid machinery to have working stability, advantage such as reliable, and can be applicable to the oil-free lubrication field.But its orbiting radius is fixed, the engagement between the scrollwork can not get radially, axial compensation (radial, tipcompliant).Requirement on machining accuracy to scroll elements is higher, has improved the manufacture cost of machine.
U. S. Patent 4300875,5752816 has disclosed and has adopted elasticity to connect in many parallelogram anti-rotation mechanism, realizes the radial displacement compensation of orbiting scroll.But, be to drive and driven relation between driving crankshaft of mentioning in the patent and the formation anti-rotation mechanism crankshaft (idlecrank shaft), be subjected to force direction opposite.After adding the elasticity connection, two kinds of cranks will have an angular phase poor, increase the uncertainty of mechanism, cause mechanism not work reliably.
Hydrojet in the volume changeable device of scroll type fluid machinery, the Castor Oil scroll body, this for realize orbiting scroll radially, the axial displacement compensation provides necessary condition.Hydrojet has also reduced the temperature in the scroll machine effectively.The hydrojet technology of scroll machine successfully has been applied on the oil lubrication scroll compressor.Because water is easy to separate from the gas after the compression, people propose to spray water in the scrollwork compression chamber and improve the service behaviour of dry type oil-free lubrication scroll compressor.How economical, solve the sealing problem of water reliably, contacting of the lubricant oil (fat) in blocking-up water and the compressor driving mechanism becomes the difficult problem of the oil-free lubrication scroll compressor tool of spraying water.So far still not having the water spray scroll compressor appears on the market.
Two scroll type fluid machineries because of it has axial force plurality of advantages such as can cancel out each other, and are paid close attention to by people.The two scroll type fluid machineries that in U.S. Patent Publication 2004-0219047A1, disclosed with multiple road moving cell, its multiple road moving cell has the counteracting axial force, drive track motion scrollwork, the anti-rotation function of equilibrium centrifugation power and realization orbiting scroll.This structure can be used for the compressor or the vacuum pump of oil-free lubrication.The parallelogram anti-rotation mechanism of trapped orbit moving radius is adopted in this invention.
Summary of the invention
The present invention is intended to make the scroll type fluid machinery that adopts the parallelogram anti-rotation mechanism, realizes the radial and axial bit shift compensation of orbiting scroll by technology such as hydrojet, elasticity connections.Improve its service behaviour, efficient and reliability, and reduce the requirement on machining accuracy of scroll elements.
The invention provides a kind of fluid machinery with orbit determination road moving radius of two scrollworks.It comprises a pair of volume changeable device, contain in each volume changeable device separately decide scrollwork and orbiting scroll.Deciding scrollwork for two is connected with support.Be furnished with at least two orbiting unit between two volume changeable devices, each orbiting unit is made up of a rotatable member and a thrust-canceling shaft.Rotatable member is rotatably supported by support, and thrust-canceling shaft is among the eccentric through-hole of rotatable member, and is rotated element and prejudicially, rotatably supports.The two ends of thrust-canceling shaft link to each other with the indirect elasticity of two orbiting scrolls respectively.When part or all of rotatable member was driven, orbiting scroll was done orbiting, meshed with deciding accordingly scrollwork, realized the continuous variation of volume.The orbiting unit has motivational drive, and centrifugal force balance, the axial force of orbiting scroll are offset and prevented function such as rotation.The outer rim of rotatable member can be made various forms such as belt wheel, gear, sprocket wheel, friction wheel or synchronizing jugged belt wheel.The orbiting unit quantitatively with pro forma variation, developing the numerous machinery of kind to be applicable to different requirements.
All bearings on the orbiting unit all are isolated among the support, and being fixed between the baffle ring of thrust-canceling shaft sponson and support has end face seal.The outer of orbiting scroll and decide that end face seal is arranged between the scrollwork.Form two relief chambers between orbiting unit and two volume changeable devices respectively.During machine run, be used to seal, liquid lubricated or the cooling volume changeable device enters volume changeable device.The method that enters can be the pressure chamber that is sprayed into volume changeable device by certain pressure liquid, or direct import suction by volume changeable device.The relief chamber internal pressure can be identical with the pressure of the workflow body source of machinery.For the water spray oil-free air compressor, if compressor sucks air by atmosphere, relief chamber can porosely communicate with atmosphere.Chamber, bearing place can communicate with relief chamber, to keep the pressure balance of the two.For keeping the cleaning in the relief chamber, filtrating equipment is used in described hole.The working pressure of the outer ring of volume changeable device is a little less than the pressure of workflow body source, and therefore the liquid that enters when proper functioning in the volume changeable device is difficult for leaking out.When shutting down, the one-way valve at row's mouth place of machine can stop the refluence of high-pressure liquid, and the solenoid valve in hydrojet loop also can cut out, and in general import also will be closed.Be stored in that fluid still has pressure in the volume changeable device this moment, and liquid releases to relief chamber.Liquid after releasing does not have ability to enter the bearing place chamber identical with relief chamber pressure again, contacts with the lubricant oil (fat) of bearing.The liquid that releases can be drained by the hole of relief chamber bottom; Or temporarily accumulate in the relief chamber, the start back is sucked back the outer collar region of volume changeable device directly or indirectly by passage.
The sidewall and the top of (as the oil-free air compressor of dry type) scrollwork all can not be in contact with one another in the dry type scroll type fluid machinery, otherwise scroll body is incited somebody to action very quick-wearing.Owing to there is liquid to enter the volume changeable device of scroll type fluid machinery, help lubricating in the volume changeable device, realize the radial and axial bit shift compensation of orbiting scroll.In the present invention, thrust-canceling shaft is directly not affixed with orbiting scroll.The both sides of each thrust-canceling shaft connect with connecting rod respectively, constitute two orbiting drive link framves, and it becomes the connecting rod of anti-rotation parallel-crank mechanism.Two orbiting drive link framves are connected with two orbiting scroll elasticity respectively.Scroll type fluid machinery when operation, orbiting scroll under action of centrifugal force, the trend that has the orbiting radius that makes self to increase, what make the scrollwork engagement radially obtains bit shift compensation.When in the compression chamber imcompressible body being arranged, orbiting scroll can produce radially and make a concession.In addition, between connecting rod rest and the orbiting scroll enclosed cavity is arranged, enclosed cavity is connected with the pressure span of scrollwork active chamber.Orbiting scroll can be with respect to connecting rod rest in the displacement of axially making trace.Fluid thrust in the enclosed cavity can partly or entirely overcome in the volume changeable device fluid end thrust of orbiting scroll is realized orbiting scroll axial displacement compensation.
In fact, also be feasible only with one-sided orbiting drive link frame.But two-orbit motion drive link frame has better rigidity.When all rotatable members all are driven, and load is evenly distributed.Thrust-canceling shaft operation itself is stable, and at this moment the orbiting drive link frame of both sides all can save.Thrust-canceling shaft directly is connected with orbiting scroll elasticity.The present invention gives the organization plan that makes each rotatable member (as belt wheel or gear) load homogenization.
In the oil-free lubrication scroll type fluid machinery, use the hydrojet technology also can improve the performance of scroll type fluid machinery to a certain extent separately.Hydrojet of the present invention and bit shift compensation technology can be applicable to comprise other structural type scroll type fluid machineries of single scrollwork equally.
Adopt hydrojet and radially, axial bit shift compensation, can reduce and leak, reduce the scroll type fluid machinery operating temperature effectively, improve the fluid output capability of scroll type fluid machinery specific power significantly, reduce noise, increase the reliability of mechanical movement, reduce the day-to-day operation maintenance cost, reduce the manufacture cost of scrollwork.For the no oily scrollwork air compressor of water spray, can realize compression process near isothermal.Obtain the more pressurized air of cleaning, environmental protection.
