The braking mechanism of the novel eddy liquid pump is composed of a four rods articulated mechanism. The utility model has the advantages of reasonable design and simple manufacturing process, and has the advantages that the volume efficiency is more than 96%, the overall efficiency is more than 76%, the noise is lower than-75dB (A), the flow value is hardly varied with lifting height, and fluids are continuously drained nearly.
Description
The invention belongs to fluid machinery--the fluid pump technical field.
Fluid pump is the general machinery equipment of industries such as oil, chemical industry, it can be widely used in national economy all departments such as the energy, communications and transportation, but use in the market that reciprocating pump and centrifugal pump more widely exist that volumetric efficiency is lower, volume is big, the life-span is short, complex structure and flow change with the variation of lift, and shortcoming such as noise is big.
The purpose of this utility model is to provide a kind of novel scroll formula liquid pump, its solve that the volumetric efficiency that existing pump exists is low, volume is big, the life-span is short and flow with problems such as lift variations.
Main points of the present utility model are, the novel scroll formula liquid pump that is provided, it is made up of dynamic and static scroll 7,5,4, main shaft 18,9,10,11,12 mouthfuls of arrestment mechanism liquid inlet holes and delivery port 13,14,15,16 etc., body 4 on the static part is processed into one with protecgulum 5 and becomes two stationary scroll dishes of mirror-symmetrical to be provided with molded lines, the two sides that is installed on the main shaft is housed between two fixed scrolls is provided with molded lines, and the position is processed with the moving scroll of several liquid delivery ports therebetween.Moving scroll 7 is along with the revolution of main shaft 18, throw of eccentric with main shaft is that radius carries out revolution motion, moving scroll 7 not rotations, small circumference revolution is done at its center around 5,4 centers of stationary scroll dish, in swirl chamber that liquid is made up of the molded lines of fixed scroll 5,4 and moving scroll 7 tangential suction in the outside of vortex filament and the formed space of end face that constitutes this swirl chamber.The swirl chamber closure, liquid is extruded, discharge swirl chamber then and enter the center portion of scroll, the line segment evolute of last 5,4 dishes of stationary scroll vertically is as the molded lines of scroll, basic identical just phase phase difference 180 degree of the two molded lines, and all molded lines axially are being mirror-symmetrical, and all molded lines wall thickness are the 3-20 millimeter, highly are the 10-50 millimeter.Thereby added-time programing work amount is reduced greatly, and eliminated the programming error, improved machining accuracy.
The present invention is equipped with axial liquid suction port 9,10,11,12 and axial delivery port 13,14,15,16 in the bottom of stationary scroll dish and moving scroll.The axial suction port 9,10,11,12 in bottom of moving scroll 7 is opened in the terminal point of moving scroll 7 molded lines inboards and the position of stationary scroll dish 5,4 molded lines engagement, axially delivery port 13,14,15,16 is the outside terminal point of moving scroll 7 molded lines and the position of stationary scroll dish 5,4 molded lines engagement, and the axial suction port of stationary scroll dish 5,4 bottoms is, the position of the inboard terminal point of stationary scroll dish-type line and the engagement of moving scroll molded lines, axially delivery port is, the position of the outside terminal point of stationary scroll dish-type line and the engagement of moving scroll molded lines.
The present invention has adopted a kind of novel anti-rotation brake mechanism, i.e. four bar linkages, just there is a main shaft 18 at stationary scroll dish 5,4 centers, around main shaft 18 the equally distributed small eccentricity axle 19 of three intervals, 120 degree is arranged, the spindle hole on the moving scroll 7 and main shaft 18 and little axle 19 on equally distributed three little axle 19 holes of main shaft 18 spans 120 degree and stationary scroll dish 5,4 match.Such mechanism makes that moving scroll 7 can only be that radius revolves round the sun with the throw of eccentric reposefully in self plane, can not rotation.Thereby realized that moving scroll meshes the requirement of running in whole motion process.
The invention has the advantages that, volumetric efficiency is greater than 96%, total efficiency is greater than 76%, noise is lower than 75dB(A), its flow changes with lift hardly, its suction, the discharge opeing body almost is continuous, the knock that does not have valve block does not have 76%, and noise is lower than 75dB(A), its flow changes with lift hardly, its suction, the discharge opeing body almost is continuous, does not have the knock of valve block, does not have reciprocating member, driving torque changes little, so motion is steadily, its noise ratio reciprocating pump hangs down 5dB(A), Duo 40% than reciprocating pump Mean time to failure, weight/power ratio lacks 50% than reciprocating pump, and efficient ratio centrifugal fluid pump improves 47-100%.
