二: Quod opus principium in Venturi tubo
Venturi est vacuum obtinendae fabrica utitur fluidum transferre industria et massa. Et communis structuram est ostensum est in Figura I. Non est opus COLLUM, a suctu area, a miscentes camera, et gutturi et diffuser. Est vacuum generans. Pelagus component de fabrica est novum, efficient, mundus et fruckica vacuo elementum ut utitur a positivum pressura fluidum fons ad generare negative pressura. Opus processus obtinendae vacuum est;
I, in sectione a puncto I ad punctum III est acceleratio scaena de dynamic fluidum in operantes COLLUM. In altior pressura motivum liquor intrat ad opus CERVIX de VENURI ad inferiore velocitas ad opus CERVIX Intus (Point I section). Cum fluit in tapited sectionem ad opus CERVIX (sectione I ad sectionem II), quod potest sciri ex fluidi mechanicis, quod continuationem aequationis advenae Q1 = Q2,
Scilicet A1V1 = a2v2
In formula A1, A2 - Cross-sectional area punctum I et punctum II (m2);
V1, V2 - In Liquor Velocitas fluit per punctum I sectionem et punctum II sectioni, m / s.
Non potest videri ex supra formula quod augmentum crucis sectionem, fluxus velocitas decrescit; Reductio ad crucem sectionem, fluxus velocitas crescit.
Nam horizontali fistulae secundum Bernoulli aequatio pro incompressible fluidorum
P1+ (1/2) * ρv12=P2+ (1/2) ρv22
In formula, P1, P2 - Quod correspondentes pressura in crucem-sectione punctum I et Point II (PA)
V1, V2 - Liquor Velocitas (M / S) fluit per sectionem ad Point I et Point II
ρ - density fluidi (kg / mc)
Potest videri ex supra formula quod fluxus velocitas dynamic fluidi auget continue et pressionem decrescit continue a puncto I sectionem ad punctum II sectionem. Cum V2> V1, P1> P2, cum V2 crescit ad certum valorem (potest pervenire celeritas sonus), P2 erit minus quam unum atmosphaericae, id est, negativa erit in sectione ad punctum III.
Cum autem motivum fluidum intrat expansion sectionem ad opus CERVIX, id est, in sectione a puncto II ad sectionem in puncto III, et velocitas motrici fluidi pergit ad oriri et pressura continues ad stillabunt. Cum dynamic fluidi pervenit ad exitus sectionem ad opus Ceo (sectionem ad punctum III), in velocitate dynamic fluida pervenit ad maximum et potest pervenire supersonic celeritate. In hoc tempore, in pressura in sectione ad punctum III ad minimum, id est vacuum gradu ad maximum, quod potest pervenire 90kpa.
02, in sectione a puncto III ad punctum V est permixtio scaena motivum fluidi et exantlaretur fluidum.
In summus celeritate fluidum formatae per dynamic fluidi ad exitus sectionem ad opus COLLUM (sectionem in puncto III) et formare in vacuo area iuxta exitus ad opus est princeps pressura erit in actione ad pressive differentia. in miscentes locus. Et exantlaretur fluidum est suxisti in mixtionem camera ad punctum IX sectionem. Per influunt a puncto IX sectionem ad punctum V sectionem, celeritas ex exantlaretur fluidi crescit continue, et pressura continues ad stillabunt ad virtutem in sectione a puncto IX sectionem ad punctum III sectionem. Et pressura in fluidi ad exitus sectionem ad opus COLLUM (Point III).
In miscentes cubiculum sectionem et fronte sectionem de faucium (sectionem ex parte III ad punctum VI), quod motivum liquidum et fluidi ut exantlaretur incipiunt et motivum fluidum est a pressura potential industria et motivum fluidum est in exantlaretur fluidum. Liquor, ut velocitas dynamic fluidum paulatim decrescit, velocitas suxit corpus paulatim crescit et duo velocitates paulatim decrescit et accedere. Denique in puncto IV sectionem, duo celeritates ad eandem celeritate, et faucium et diffundens ex Venturi sunt dimitti.
三:Et compositionem et opus principium de se-priming sentinam coetus ut utitur exhauriunt Gas fluxus ex Diesel engine obtinere vacuum
Diesel engine exhauriunt refers ad exhauriunt Gas emittitur a Diesel engine post ardenti Dyel oleum. Pertinet exhauriunt Gas, sed exhauriunt Gas est quaedam moles calor et pressura. Post probationem a relevant investigationis departments, in pressura ex exhauriunt Gas exit a Diesel engine instructa cum turbocharger [III] potest pervenire 0.2MPA. Ex perspective ex efficiente usu industria, environmental tutela et reductionem operating costs, quod factum est in investigationis topic ad utendum est exhauriunt Gas a operatione de Diesel engine. Et Turbocharger [III] utilitas exhauriunt Gas ex operatione de Diesel engine. As a power running component, it is used to increase the pressure of the air entering the cylinder of the diesel engine, so that the diesel engine can be burned more fully, so as to improve the power performance of the diesel engine, improve the specific power, improve the fuel economy and reduce the noise. The following is a kind of use of the exhaust gas discharged from the operation of the diesel engine as the power fluid, and the gas in the pump chamber of the centrifugal pump and the water inlet pipe of the centrifugal pump is sucked out through the venturi tube, and the vacuum is generated in the pump chamber of the centrifugal pump and the water inlet pipe of the centrifugal pump. Sub actum atmosphaerica pressura, aquam inferior quam aqua fons est in iniustos centrifuga sentinam intrat in initus pipeline de centrifuga sentinam et sentinam in lente pipele et sentinam laoreet ad consequi normalem aquae. Structura est ostensum est in Figura II, et operatio processus est ut sequitur:
Ut ostensum est in Figura II, in aquae urgere centrifuga pump est coniuncta ad Pipeline demergi in piscinam sub aqua sentinam exitus aquae et pipeline. Ante Diesel engine decurrit, aquae outlet valvae centrifuga sentinam clausit, portam CYMBALON (VI) aperitur et centrifuga sentinam separatur a Diesel engine per lacessit. Post Diesel engine incipit et decurrit Northmanni, in porta CYMBALON (II) est clausa, et exhauriunt Gas ex exhaurit a melle engine intrat in VENURI Pipe per exhaurit a exhaurit pipe (XI). In this process, according to the principle of venturi tube, the gas in the pump chamber of the centrifugal pump enters the venturi tube through the gate valve and the exhaust pipe, and is mixed with the exhaust gas from the diesel engine and then discharged from the exhaust pipe. In this way, a vacuum is formed in the pump cavity of the centrifugal pump and the water inlet pipeline of the centrifugal pump, and the water in the water source lower than the water inlet of the centrifugal pump enters the pump cavity of the centrifugal pump through the water inlet pipe of the centrifugal pump under the action of atmospheric pressure. Cum sentinam cavum centrifuga sentinam et aquae aspera pipeline repleti aqua claudere porta CYMBALON (VI), aperire ostium CYMBALON (II Centrifuga, et aperire aquae valvae Centrifuga et aperire ad lorica sentinam posuit animi et aperire in lore valvae set incipit et ad lorem more centrifuga, et aperire ad lorica pump posuit animi et aperire in lore centrifuga, ut in lorea more sentinam set incipit et aperire solet engine sentinam posuit animi ad opus Northmanni. Aqua copia. Post temptationis, in Diesel engine pump posuit potest sugere aqua II metris infra in livore pipe centrifuga sentinam in sentinam cavum de centrifuga sentinam.

Quod Diesel engine sentinam paro hoc structuram potest sugere in aquam inferior aquae aspera centrifuga sentinam et plenum usum exhauriunt Gas ex operatione Venturi fistulam ad altum quod non est per Diesel Venturi fundo in a summo, facit per Diesel Venturi fistula in a summo, facit per Diesel Venturi Sentinarii Set quod non habet, facit Diesel VENURI Sententiam Set quod non habet, facit Diesel ENGUGNIFICATIONE ENGUALIS Set quod non est sui priming FUNDINALE ENGUAL. Cum auto-priming munus.
四: amplio aqua effusio altitudo in Diesel engine pump posuit
Et Diesel engine sui priming sentinam paro describitur supra habet a se-priming munus per usura exhauriunt Gas dimitti ab Diesel engine ad influere per venturi fistulam obtinere vacuum. Tamen, in potestate liquor in Diesel engine pump posuit cum hoc structuram est exhauriunt Gas dimitti ab in Diesel engine et pressura est relative humilis, ita et in aqua absorption et relative humilis, quod fines et fines est ad range de sentinam pump est. Si suctu altitudo centrifuga sentinam augeri, vacuum gradu suctionis area venturi tubo augeri. Secundum opus principium venturi fistulam, ut amplio in vacuo gradu de suctu area de venturi tubo, opus COLLUM de Venturi tubo est disposito. Potest fiet a Mors COLLUM Type, aut etiam supersonic CERVIX genus, et etiam auget originale pressura de dynamic fluidum fluunt per venturi.
Ad augendam originale pressura de venturi motivum fluidi fluunt in Diesel engine pump posuit, a turbocharger potest installed in exhaurit pipe of theyel engine [III]. Turbocharger [III] est aeris compressione fabrica, quod utitur in inertia impetu exhauriunt Gas metus ex machinam ad ventilabis in Turbine in Turbine thalamum, et Turbine in Turbine in Turbine, et Turbine Drescit in Turbine Impellor et Impellrix comprimit aërem. Et structuram et operantes principle ostenditur in Figura III.. Turbocharger in tres genera: princeps pressura, medium pressura et humilis pressura. Et output compressis Gas pressuras sunt: princeps pressura est major quam 0.3MPa, medium pressura est 0.10@3mpa, humilis pressura est minus quam 0,1mpa, et compressa est stabilis per Turbocharger est pressura est stabile. Si compressed Gas input in Turbocharger adhibetur ut venturi potentia fluidi, altiorem gradum vacuo potest adeptus est, quod aqua absorption altitudinem in Diesel engine pump est auctus.
