Three grades of vane pump operation logics:
The first order: axial flow level:
The axial flow level adopts stainless steel to make, support by bearings at both ends, one end is by motor direct-drive, in the operation process, axial flow level impeller provides first order absorption water inlet to play the pumping head effect, with centrifugal level by yarn cylinder recirculation water being drawn water to centrifugal level, owing to be full of liquid in the pump, centrifugal level impeller quick rotation, the blade of impeller are ordered about liquid rotations of drawing water, and dependence inertia was to the impeller outer edge diffluence when liquid rotated, impeller is from suction chamber inspiration liquid simultaneously, in this course, the liquid in the impeller streams blade, and liquid effects lift is in blade in streaming motion, blade is with a lift equal and opposite in direction therewith conversely, the masterpiece that direction is opposite is used for liquid, this power is done work to liquid, makes liquid obtain energy and flows out impeller, and at this moment the kinetic energy of liquid and pressure energy all increase.Under variable-frequency motor drove, the axial flow grade blade throws away water transport when delivering to the valve port of centrifugal level and going into to hold full open, and flow increased, and the current reinforcement that is produced strengthens, and forms first order lift.
The second level: centrifugal level:
Centrifugal level is close to the axial flow level, and the lift that the axial flow level relies on the wing cascade opposing connection flow liquid body of rotary blade to produce transmits energy and gives centrifugal level impeller.Impeller is all proofreaied and correct through static balance.Centrifugal level principle is to compile extruding by after rotor (impeller) high speed rotating low-pressure fluid drive outwards being thrown away outlet, forms high-pressure fluid; Turbulence pump is by turbine the outer low pressure fluid to be drawn into progressively to derive to the center middle high pressure of extruding back formation in the turbine chamber to form high-pressure fluid.Centrifugal level is to be connected with the axial flow level is coaxial, and essence is a type of three grades of vane pumps.The hydraulic propeller of this pump is made up of water inlet flow channel, impeller, diffuser and spout.Pump characteristic curve (lift--flow curve, efficient--flow curve, lift--suction inlet specific speed curve) has reflected the Mathematical Modeling of the kinematic parameter (rotating speed, circumferential and axial speed) of pump, pump performance be can measure out, power conversion usefulness, propulsive performance and anti-cavitation performance etc. comprised.Mixing pump adopts the performance curve of mixed-flow water jet propulsion pump, lift--flow curve and efficient--when comprising different rotating speeds under the non-cavitation conditions under flow curve and the cavitation conditions lift and efficient obtain this hydraulic propeller and in flow rates, be used to find the solution the pump performance curve with the correction function curve that the suction inlet specific speed changes.
The third level: fixing impeller inducer level:
Fixedly the impeller inducer level adopts the stainless steel manufacturing, and the impeller that blade is made with stainless steel is welded on (or blade enclosure) on the impeller base, is anchored on the impeller base, and blade and impeller base adjacently situated surfaces are carved with angle line.The blade angle degree is generally 45 degree, and this blade angle is opposite with centrifugal level water outlet direction.The impeller inducer pump is the rotary water current of the and then centrifugal level water conservancy diversion that drives in the wrong direction, and promptly current are rotations and guide vane wheel is fixed, and make the fixedly same vane pump of impeller inducer level shape.After centrifugal level throws away water and flows to the third level, current rotate, impeller inducer is to be fixed on the impeller housing of impeller base, after making the current scour impeller inducer, the current of rotation throw away and reach current and become direct current to gooseneck cover outlet by rotation along impeller inducer, reach the third level raising lift lift that boosts.
Three grades of vane pumps that adopt change high specific revolution centrifugal pump (specific revolution=200～300) into, make it characteristic curve variation has also taken place.According to blade centrifugal pump design theory, on flow and power characteristic, the power of centrifugal pump changes faster than three grades of vane pumps under the same terms.Because yarn package dyeing machine main circulation pump motor has all adopted alternating frequency conversion technique now, pass through rotation speed change, guaranteeing under the constant condition of the efficiency of pump, can provide different flows and lift, so flow based on centrifugal pump. power changes characteristics, can under different flow, fully reduce power consumption.
Centrifugal pump is compared with three grades of vane pumps, and its flow and efficiency characteristic curve are also relatively milder, and in the scope of changes in flow rate, the scope that departs from best efficiency point is also little.This load to change or the end-on water capacity easily takes place the fiber (as viscose) of swelling cheese, and in Variations in Flow Changes, equipment has higher operating efficiency all the time.
The utility model adopts centrifugal pump to add the pulsating fluid principle of dynamics of axial-flow pump, specifically is to have adopted the Bernoulli's theorem hydrodynamic equations.Bernoulli's theorem is flow regime, the characteristics of motion, power conversion and the fluid of research fluid and the equation of the problems such as interaction force between solid wall surface, comprise three big equations such as continuity equation, Bernoulli equation and the equation of momentum, the relation of the quality when they have explained current stabilization respectively, energy and momentum and rule.Bernoulli equation has wherein solved the flow field problem of liquid with law of conservation of energy, occupies critical role in hydrodynamics.Bernoulli equation has disclosed the energy variation rule in the liquid flow process, and promptly flowing liquid not only has pressure energy and gesture potential energy, and because it has certain flow velocity, thereby also have kinetic energy.Suppose that ideal liquid makes constant flow (the indeclinable liquid form of pressure, flow velocity and density) in pipeline, its ideal form be:
Or
Or
Wherein: P
1, P
2--the pressure (pressure is the pressure in the physics in the hydraulic drive) at flow section place;
v
1v
2--the flow at flow section place;
h
1, h
2--the flow section place is apart from the height (getting the specific position horizontal plane as datum level) of datum level;
ρ g--density of liquid and acceleration of gravity.
The meaning of this formula is for making the ideal liquid of constant flow in closed conduit, the energy of its three kinds of forms can transform in flow process mutually, but energy sum perseverance is a definite value on each flow section.Actual flow liquid is because toughness so can produce frictional force in the flow process, has energy loss; The size and dimension variation of pipeline all can make the liquid miscarriage give birth to disturbance in the oil circuit simultaneously, also causes energy loss.Actual flow liquid flow velocity (flowing through the liquid volume of a certain flow section in the unit interval) on flow section is inhomogeneous again, if calculate with mean flow rate, will inevitably produce error, need add a correction factor, and therefore, the Bernoulli equation of actual liquid is:
Wherein: a
1, a
2-kinetic energy correction factor;
Δ p
wThe energy loss that-unit volume liquid flows between two flow sections.
In calculating hydraulic system pressure, valve port motion and liquid flow process, during energy loss, all to use Bernoulli equation.
Bernoulli's theorem: the fast local static pressure of flowing velocity was little when perfect fluid was made current stabilization in pipe, and the slow local static pressure of flowing velocity is powerful.
Bernoulli equation: the summation of its kinetic energy, potential energy and pressure remained unchanged when perfect fluid was made current stabilization.
Also having a key concept when three grades of vane pumps of design the utility model, is exactly specific discharge.Specific discharge is an important technical parameter in the cheese dyeing technology, and it is characterized in the dye liquor amount of passing every kilogram of yarn in the unit interval, and its unit is L/kgmin.Adopt rational specific discharge, can increase the main pump lift, thereby guarantee the level-dyeing property of yarn and once dye accurate rate, and raise the efficiency, cut down the consumption of energy.Three basic processes of dye process: absorption, diffusion and set.Be exactly in the time of setting, dyestuff is dyed on evenly and anchor on the yarn fibers.According to dyeing theory, the pollutant yarn must constantly contact with dyestuff, just can finish three basic processes of dying.In this process, except controlling the dyeing rate with temperature, mainly be by dye liquor circulation guaranteeing the temperature homogeneity of whole pollutant (yarn), and with dyestuff exchange frequency equalization.Therefore, specific discharge plays important effect in cheese dyeing, and the main foundation that equipment main pump flow is chosen is exactly a specific discharge.When guaranteeing that the effective dye liquor cycling rate of the circulatory system 90% is above, the specific discharge of cone dyeing machine can be chosen in more than the 35L/kgmin.Because the specific revolution of pressing the selected main pump of this specific discharge belongs to the centrifugal pump of high specific revolution less than 300, therefore can reduce main pump import and export caliber, make that the water amount in the pipeline reduces, reduce the bath of dye liquor ratio.Specific revolution is provided by following formula:
Specific revolution is lower than 300 and has the centrifugal pump function, is higher than 300 and belongs to mixing pump, exceeds and belongs to axial-flow pump more than 500.
The principle that adopts yarn dyeing machine of the present utility model is that spindle is put creel into and tightened up, drive three grades of vane pumps by the control motor speed and be ejected into creel, dye liquor is ejected into spindle outflow layer through creel and loops back in the yarn cylinder body, dye liquor is promoted dye liquor to 30 meter lift pressure through three grades of vane pumps, reach the cheese dyeing specific discharge, dyeing liquid to being ejected into spindle, and is finished dyestuff to dying process on the spindle with high rapid pulse stream folk prescription.In whole dyeing course, water only is the solvent that soaks as the solvent of dyestuff and spindle.Therefore, required bath raio is very low.The utility model is applied to ultralow bath raio yarn dyeing machine, makes yarn dyeing machine have following advantage:
(1) saves dyestuff and auxiliary agent
Adopting the maximum different of arteries and veins of the present utility model stream yarn dyeing and common overflow or injection yarn dyeing, is exactly that it can realize yarn dyeing under low-down bath raio (below 1: 3) condition.This low bath raio yarn dyeing condition can be brought the variation of dyestuff to the spindle dye-uptake, as: when the REACTIVE DYES yarn dyeing, the substantivity of dyestuff improves along with the reduction of yarn dyeing bath raio, dyestuff is reduced the interdependence of accelerant (as electrolyte such as glauber salt, salt), dye-uptake improves, thereby less color-fixing agent (alkaline agent) just can obtain higher degree of fixation, and the minimizing of color-fixing agent can reduce the hydrolysis of dyestuff again.Therefore, in order to control the dyeing rate of dyestuff, should use direct lower REACTIVE DYES.
(2) level dyeing of realization spindle and dye liquor
Few water-bath than process in, must be by spindle and the enough exchange number of times of dye liquor, just can finish and dye on the dyestuff, arteries and veins flows yarn dyeing and also relies on this mode to realize that dyestuff is to dying on the spindle.Obviously, the exchange number of times of spindle and dye liquor is many more in the unit interval helps level dyeing more and shortens the yarn dyeing time.The low dye liquor of arteries and veins stream yarn dyeing bath raio, cycle frequency height and spindle band liquid measure are low can to make very fast spindle of the speed of service and the high-frequency exchange of dye liquor be beneficial to level dyeing.Under suitable dyeing was supported, arteries and veins stream yarn dyeing can be realized quick yarn dyeing.This utility model is that water does not soak spindle, and there is not resistance in dye liquor to spindle, spindle dyeing is had more dye effect on the advantage, and bring a series of benefits such as water-saving economize on electricity.
(3) arteries and veins stream sprays the raising of spindle cycle frequency
When common overflow or injection yarn dyeing equipment yarn dyeing, the speed of service of spindle is decided by the dye liquor emitted dose, and the reduction of dye liquor emitted dose can make the spindle speed of service slack-off, and further influences the exchange frequency of spindle and dye liquor.And during arteries and veins stream yarn dyeing, the spindle circulation is by the traction of arteries and veins stream, and the cycle frequency of dye liquor can independently be controlled according to the needs of technology, and change dye liquor amount can't influence the cycle frequency of spindle.
(4) the yarn dyeing ingot improves absorption, diffusion and set on the dyestuff
The yarn dyeing process comprises absorption, diffusion and three basic processes of set of dyestuff, wherein the fixation process time longer, and the absorption of dyestuff is relevant with the relative motion of dye liquor and spindle with diffusion process.By hydrodynamics as can be known, the dynamic viscosity of liquid reduces with the rising of temperature, and the dynamic viscosity of arteries and veins stream improves with the rising of temperature.For arteries and veins stream yarn dyeing, raise the raising of the reduction of dye liquor dynamic viscosity and gas dynamic viscosity with temperature, more help breaking the dynamic equilibrium of absorption and diffusion boundary layer, make this boundary layer thickness attenuation, be beneficial to dyestuff and move, thereby shorten the yarn dyeing time to fibrous inside.Meanwhile, the variation of two kinds of fluid motion viscositys also provides condition for the speed of service that improves spindle.That is to say that under the constant situation of circular flow, the increase of arteries and veins stream viscosity has improved its adhesive force to spindle, and the spindle speed of service is accelerated, more help dyestuff to spindle evenly on dye.
(5) temperature guarantees the yarn dyeing level dyeing
Because arteries and veins stream yarn dyeing bath raio is lower, and the dye liquor and the free dye bath (circulation dye bath) of spindle and absorption thereof are in released state in the storage creel body, so the temperature when the yarn dyeing spindle flows through arteries and veins always will be higher than the temperature of spindle in the yarn cylinder body, especially when being rapidly heated to 130 ℃, both temperature difference can reach about 10 ℃.The uniformity of dying spindle in the process on the arteries and veins stream yarn dyeing makes dye liquor replenish temperature by control yarn cylinder bottom portion heat exchanger coil usually, and the circulating temperature speed of heating rate and spindle is realized.Therefore, control spindle and dye liquor exchange fast, can guarantee the dyestuff level dyeing, make spindle obtain the even temperature yarn dyeing again.
The utility model compared with prior art has following advantage and beneficial effect:
1, the utility model adopts the form of three grades of vane pump series connection can reach desired lift, and overcome the shortcoming of axial-flow pump and centrifugal pump respectively, in conjunction with the strong point of the two, allow in bath raio very little, water level still can reach the specific discharge of setting just under creel the time, and spindle is Rapid Cycle in dyeing machine, avoided under low bath raio condition, spindle easily produces the phenomenon of layer aberration.Because the dye liquor less relatively (spindle in the storage creel separates with cheese cylinder dye liquor) that spindle is contained, even so under the high-temperature pressure dyeing condition, can not produce excessive tension force to spindle yet, particularly, provide advantage to the wet processing of (as containing elastic polyurethane fiber class spindle) of responsive spindle.Spindle is in the Rapid Cycle of high-temperature pressure dyeing and low bath raio dye liquor, improved the exchange frequency of spindle and dye liquor in the dyeing course, helps the level dyeing of the fast superfine fibre spindle of specific discharge cheese dyeing surface area, dyeing rate.In addition, the arteries and veins of spindle and dye liquor flows quick exchange frequency, is accompanied by arteries and veins stream flushing action, handles at enzyme in the technologies such as (boil as enzyme desizing, enzyme float, enzyme polishing) and fibriilar fibrillation, reaction speed and raising treatment effect to accelerating treatment fluid have played very important effect.
2, the utility model has been realized ultralow bath raio.Because adopt gas as the power that drives the spindle operation, spindle can move under the state of no liquid, and " three grades of vane pump yarn dyeing machines with ultralow bath raio " can be dyeed with minimum dye liquor, the bath raio during dyeing is very little.Using the bath raio of " three grades of vane pump yarn dyeing machines with ultralow bath raio " dyeing purified cotton yarn ingot is 1: 3, and dying pure bath raio of washing spindle is 1: 2.5.Because bath raio is little, dye liquor does not soak water, and circulation dye liquor infiltration spindle speed is fast, the dye liquor resistance is few, spindle repeatedly exchanges with dye liquor in a short period of time, has improved the exchange frequency between dye liquor and the spindle, therefore can obtain higher dyeing reappearance and once be coloured to the power height.Super bath raio is to dyeing success dyeing quality and reproducible effective.Because bath raio is little, three grades of vane pump dyeing machines are compared with traditional liquid stream arteries and veins stream dyeing machine, have reduced the total water consumption of technical process, and have had lower dying material consumption, lower quantity of wastewater effluent.
To dye 1 ton of cotton yarn is example, and " three grades of vane pump yarn dyeing machines with ultralow bath raio " see Table 1 with traditional liquid-flow dyeing machine in the contrast of the cost consumption aspect water, electricity, steam and the sewage disposal.Because bath raio is little, there is not water in the dyeing course in the master cylinder, that is to say that spindle is not immersed in the dye liquor, the liquid level of dye liquor is lower than spindle, therefore, spindle subsidiary not too much dye liquor, weight in the process that promotes is lighter, even before entering arteries and veins stream very high acceleration is arranged, spindle also can be not easy scratch at high-temperature pressure dyeing under the low-tension.Simultaneously, spindle mainly is to flow by arteries and veins in arteries and veins stream, compares with liquid stream, and " three grades of vane pump yarn dyeing machines with ultralow bath raio " arteries and veins stream is softer to the effect of spindle, has reduced the tension force in the spindle running.
Three grades of vane pump yarn dyeing machines of the ultralow bath raio of table 1 and traditional overflow dyeing machine pluses and minuses compare:
3, the sealing ring in the utility model all adopts Teflon rubber ring (PTFE) sealing.In traditional liquid stream arteries and veins stream dyeing machine, dye liquor produces dye liquor thrust by the vane pump rotation and flows, dye liquor is sprayed at dye liquor on the spindle, make spindle contact and obtain the power of shuttling movement with dye liquor, the operation of spindle is mainly by the friction (dye liquor passes to spindle with kinetic energy) between dye liquor and the spindle.Because the density of liquid stream is bigger, with the continuous friction process of spindle in, spindle is produced very big impulsive force, can cause the fracture and the balling-up of fiber, influence the outward appearance of spindle.In processing during tight spindle, dye liquor the power on the spindle of being delivered to can cause the displacement of warp thread and the disorganize structure, influences the class of processed spindle.
In " three grades of vane pump yarn dyeing machines with ultralow bath raio ", the high speed dye liquor flows out after entering creel, is sprayed directly on to the spindle surface after dye liquor and the spindle bank pod apertures, and penetrability is strong, contact area is big and evenly.Spindle density is lower, under the flushing of high rapid pulse stream, makes spindle obtain splendid Color.
Have three grades of vane pumps of ultralow bath raio owing to adopted the Teflon sealing, reduced the friction between impeller and the diversion shell, for spindle provides more comfortable processing environment, even yarn moves the yarn face that also can not wear and tear under high speed.Simultaneously, spindle fully launches and shake in high rapid pulse stream, in cyclic process, constantly change the arteries and veins stream mode, guarantee the level-dyeing property of spindle thus, reduced the chance that folding line occurs, can solve the insoluble fine wrinkle problem of liquid stream arteries and veins stream dyeing machine, improve the crudy and the product specification of spindle.
4, three grades of vane pump yarn dyeing machine water consumptions that the utlity model has ultralow bath raio have reduced 69%, one kilogram of yarn only needs 3 kg of water, power consumption reduces 83%, process time reduced to 6-8 hour from original 7.5-8.0 hour, than traditional dyeing time shortening 1-2 hour, steam consumption quantity reduces 58%, and the dyeing assistant consumption reduces 57%.Yarn dyeing process has increased the pulsating fluid dyeing course, makes the spindle quality reduce interior, the domestic and abroad aberration of single cheese, and the aberration between layer and the layer, so problems such as the pipe of yarn face is poor, COLOR FASTNESS are resolved the level-dyeing property of raising yarn.For traditional yarn dyeing machine, total water consumption 2.5-3 kg of water/per kilogram yarn.
5, the utility model mainly is to adopt centrifugal pump to add pulsating fluid power (arteries and veins stream) staining technique of axial-flow pump (three grades of vane pumps).Its principle is to drive three grades of vane pumps by the control motor speed to be ejected into creel, spindle is put creel into and is tightened up, dye liquor is ejected into spindle outflow layer through creel and loops back in the yarn cylinder body, dye liquor is promoted dye liquor to 30 meter lift pressure through three grades of vane pumps, reach the cheese dyeing specific discharge, dyeing liquid to being ejected into spindle, and is finished dyestuff to dying process on the spindle with high rapid pulse stream folk prescription.In whole dyeing course, water only is the solvent that soaks as the solvent of dyestuff and spindle.Therefore, required bath raio is very low.The reduction of bath raio means the required hot water of yarn dyeing heating, the consumption of dyeing chemical dyestuff and the reduction of blowdown, and the process time of dyeing has been shortened in arteries and veins stream dyeing efficiently, has also reduced power consumption.The economy that arteries and veins stream dyeing meets ecological, environmental protective four key elements---the minimum consumption of water, the energy, auxiliary agent, time of dyeing.
