Njengoko imozulu isiya iphola, mhlawumbi awusayi kuzikhathaza kakhulu ngokunyuka kwamaqondo obushushu e-oyile, kodwa inyaniso yeyokuba nayiphi na inkqubo ye-hydraulic ye-industrial esebenza ngaphezulu kwe-140 degrees ishushu kakhulu.Qaphela ukuba ubomi beoyile bunesiqingatha kwi-18 degrees ngaphezu kwe-140 degrees.Iinkqubo ezisebenza kumaqondo obushushu aphezulu zinokwenza i-sludge kunye ne-varnish, enokubangela ukuba i-valve plugs ibambelele.
Iimpompo kunye neenjini zehydraulic zidlula ioyile eninzi kumaqondo obushushu aphezulu, nto leyo ebangela ukuba umatshini abaleke ngesantya esiphantsi.Kwezinye iimeko, amaqondo okushisa aphezulu e-oyile abangela ukulahlekelwa kwamandla, okubangela ukuba i-motor yepompo yokuqhuba iqhube ngakumbi ngoku ukuqhuba inkqubo.Amakhonkco e-O nawo aqina kumaqondo obushushu aphezulu, abangela ukuvuza okungakumbi kwinkqubo.Ke, zeziphi iitshekhi kunye neemvavanyo ekufuneka zenziwe kwiqondo lobushushu leoli ngaphezulu kwe-140 degrees?
Yonke inkqubo yehydraulic ivelisa umlinganiselo othile wobushushu.Malunga ne-25% yegalelo lamandla ombane liya kusetyenziselwa ukoyisa ilahleko yobushushu kwisixokelelwano.Nanini na xa ioli ithuthwa ibuyiselwa kwidama kwaye ingenzi msebenzi uluncedo, ubushushu buyakhululwa.
Ukunyamezela kwiimpompo kunye neevalvu zihlala ngaphakathi kwishumi lamawaka e-intshi.Oku kunyamezelwa kuvumela amanani amancinci e-oyile ukuba aqhubeke edlula amacandelo angaphakathi, ebangela ukuba amaqondo obushushu olwelo anyuke.Njengoko ioli ihamba kwimizila, idibana nochungechunge lokuchasana.Umzekelo, izilawuli zokuqukuqela, iivalvu ezilinganayo, kunye neevalvu zeservo zilawula umyinge wokuhamba kweoyile ngokunqanda ukuhamba.Njengoko ioli idlula kwivalve, "i-pressure drop" iyenzeka.Oku kuthetha ukuba uxinzelelo lwe-valve yokungena luphezulu kunoxinzelelo lokuphuma.Nanini na xa ioli iphuma kuxinzelelo oluphezulu ukuya kuxinzelelo oluphantsi, ubushushu buyakhutshwa kwaye bufunxelwe yioyile.
Ngethuba loyilo lokuqala lwenkqubo, imilinganiselo yetanki kunye nokufudumala kwenzelwe ukususa ubushushu obuveliswayo.Eli chibi livumela ubushushu obuthile ukuba buphume ngeendonga ukuya emoyeni.Xa ubungakanani obufanelekileyo, umtshintshi wobushushu kufuneka aphelise ibhalansi yobushushu, evumela inkqubo ukuba isebenze kumaqondo obushushu amalunga ne-120 degrees Fahrenheit.
Umzobo 1. Ukunyamezelana phakathi kwepiston kunye ne-cylinder yempompo yokufuduswa kwembuyekezo yoxinzelelo malunga ne-0.0004.
Olona hlobo luqhelekileyo lwempompo luxinzelelo lwempompo yepiston ehlawulelwayo.Ukunyamezela phakathi kwepiston kunye ne-cylinder malunga ne-0.0004 intshi (Umfanekiso 1).Inani elincinci leoli elishiya ipompo liloyisa oku kunyamezela kwaye ligeleza kwi-casing yepompo.I-oyile ke iye iqukuqelele emva etankini ngomgca we-crankcase drain.I-drain stream kule meko ayenzi nawuphi na umsebenzi oluncedo, ngoko iguqulwa ibe shushu.
Ukuhamba okuqhelekileyo ukusuka kumgca we-crankcase drain yi-1% ukuya kwi-3% yomthamo wempompo ephezulu.Umzekelo, impompo ye-30 GPM (gpm) kufuneka ibe ne-0.3 ukuya kwi-0.9 GPM yeoli ebuyela kwitanki nge-drain ye-crankcase.Ukunyuka okubukhali koku kuhamba kuya kubangela ukunyuka okukhulu kweqondo lokushisa kweoli.
Ukuvavanya ukuhamba, umgca unokumiliselwa kwisitya esaziwayo kunye nexesha (Umfanekiso 2).Musa ukubamba umgca ngexesha lovavanyo ngaphandle kokuba uqinisekise ukuba uxinzelelo kwi-hose lusondele kwi-0 pounds per square intshi (PSI).Kunoko, yikhusele kwisitya.
Isilinganisi-manzi sokuhamba sinokufakwa ngokusisigxina kumgca we-crankcase drain to monitor flow.Olu hlolo olubonakalayo lunokwenziwa ngamaxesha athile ukumisela ubungakanani bendlela yokudlula.Umpompo kufuneka utshintshwe xa ukusetyenziswa kweoli kufikelela kwi-10% yomthamo wempompo.
Uxinzelelo oluqhelekileyo oluhlawulelwayo lwempompo ye-displacement luboniswe kuMzobo 3. Ngexesha lokusebenza okuqhelekileyo, xa uxinzelelo lwenkqubo lungaphantsi kwe-comensator setting (1200 psi), imithombo ibamba i-swashplate yangaphakathi kwi-angle yayo ephezulu.Oku kuvumela ipiston ukuba ihambe ngokupheleleyo ngaphakathi nangaphandle, ivumela impompo ukuba ikhuphe umthamo omkhulu.Ukuhamba kwindawo yempompo kuvaliwe ngumxhasi wembuyekezo.
Ngokukhawuleza ukuba uxinzelelo lwanda ukuya kwi-1200 psi (umzobo 4), i-compensator spool ihamba, iqondise ioli kwi-cylinder yangaphakathi.Xa i-cylinder yandiswa, i-angle ye-washer isondela kwindawo ethe nkqo.Ipompo iya kunika ioli eninzi njengoko ifunekayo ukugcina i-1200 psi setting spring.Okuphela kobushushu obuveliswa yimpompo kweli nqanaba yioyile ehamba ngepiston kunye nomgca woxinzelelo lwecrankcase.
Ukumisela ukuba kungakanani ukushisa okuza kuveliswa yimpompo xa uhlawulelwa, sebenzisa le fomula ilandelayo: Amandla eHorse (hp) = GPM x psi x 0.000583.Ukucinga ukuba ipompo ihambisa i-0.9 gpm kwaye i-joint yokwandisa imiselwe kwi-1200 psi, ukushisa okwenziwa ngulo: HP = 0.9 x 1200 x 0.000583 okanye 0.6296.
Ngethuba nje inkqubo epholileyo kunye ne-reservoir inokuzoba ubuncinane i-0.6296 hp.ubushushu, ubushushu beoyile abuyi kunyuka.Ukuba izinga lokudlula liye landa ukuya kwi-5 GPM, umthwalo wokushisa unyuka ukuya kwi-3.5 yamahashe (hp = 5 x 1200 x 0.000583 okanye 3.5).Ukuba i-cooler kunye ne-reservoir ayikwazi ukususa ubuncinane i-3.5 ye-horsepower yokushisa, ukushisa kweoli kuya kunyuka.
Irayisi.2. Jonga ukuhamba kweoli ngokudibanisa umgca we-crankcase drain kwisitya esaziwayo sobukhulu kunye nokulinganisa ukuhamba.
Iimpompo ezininzi ezihlawulelwe ngoxinzelelo zisebenzisa ivalve yokukhulula uxinzelelo njenge-backup kwimeko apho i-spool yembuyekezo ibambeke kwindawo evaliweyo.Ukuseta i-valve yokunceda kufuneka ibe yi-250 PSI ngaphezu kwe-comensator ye-pressure setting.Ukuba ivalve yoncedo isetiwe phezulu kunolungiselelo lwembuyekezo, akukho oli kufuneka ihambe ngespool yevalve yokukhulula.Ngoko ke, umgca wetanki kwi-valve kufuneka ube kwiqondo lokushisa eliphantsi.
Ukuba umxhasi ugxininise kwindawo eboniswe kumkhiwane.I-3, ipompo iya kuhlala ihambisa umthamo ophezulu.I-oyile eyongezelelweyo engasetyenziswanga yinkqubo iya kubuyela kwitanki ngevalve yokukhulula.Kule meko, ubushushu obuninzi buya kukhutshwa.
Amaxesha amaninzi uxinzelelo kwinkqubo luhlengahlengiswa ngokungenamkhethe ukwenza umatshini usebenze ngcono.Ukuba umlawuli wendawo kunye ne-knob ubeka uxinzelelo lwembuyekezo ngaphezu kwe-valve yokumisa i-valve, i-oyile engaphezulu ibuyela ngevalve yokukhulula kwi-tank, ibangela ukuba ubushushu be-oyile bunyuke ngama-30 okanye ama-40 degrees.Ukuba umbuyekezi akashukumi okanye usetelwe ngentla kwesiseko sevalve yoncedo, ubushushu obuninzi bunokuveliswa.
Ukucinga ukuba ipompo inomthamo omkhulu we-30 gpm kwaye i-valve yokunceda imiselwe kwi-1450 psi, ubungakanani bobushushu obuveliswayo bunokumiselwa.Ukuba i-30 ye-horsepower motor motor (hp = 30 x 1450 x 0.000583 okanye i-25) yayisetyenziselwa ukuqhuba inkqubo, i-horsepower ye-25 iya kuguqulwa ibe shushu ngokungasebenzi.Njengoko iiwathi ezingama-746 zilingana namandla ehashe elinye, i-18,650 watts (746 x 25) okanye i-18.65 yeekhilowathi zombane ziya konakala.
Ezinye iivalvu ezisetyenziswa kwisixokelelwano, ezifana neevalvu zebhetri kunye neevalvu zokopha, zinokungavuleki kwaye zivumele i-oyile ukuba idlule itanki yoxinzelelo oluphezulu.Umgca wetanki wezi valve kufuneka ube kwiqondo lobushushu le-ambient.Omnye unobangela oqhelekileyo wokuvelisa ubushushu kukugqitha itywina lepiston yesilinda.
Irayisi.3. Lo mzobo ubonisa uxinzelelo lwempompo yokufuduka okuguquguqukayo okuhlawulelwayo ngexesha lokusebenza okuqhelekileyo.
Irayisi.4. Nika ingqalelo kwinto eyenzekayo kwi-spool yempompo yembuyiselo, i-cylinder yangaphakathi, kunye ne-swash plate njengoko uxinzelelo lukhula kwi-1200 psi.
Isitshintshi sobushushu okanye isipholileyo kufuneka sixhaswe ukuqinisekisa ukuba ubushushu obugqithisileyo bususiwe.Ukuba i-air-to-air exchanger heat isetyenzisiwe, ii-cooler fins kufuneka zicocwe ngamaxesha athile.Kusenokufuneka i-degreaser ukucoca amaphiko.Ukutshintsha kweqondo lobushushu elivula i-fan epholileyo kufuneka kumiselwe kwi-115 degrees Fahrenheit.Ukuba kusetyenziswe isixhobo sokupholisa amanzi, ivalve yokulawula amanzi kufuneka ifakwe kumbhobho wamanzi ukulawula ukuhamba kombhobho opholileyo ukuya kuma-25 ekhulwini ngalinye lokuhamba kwe-oyile.
Itanki yamanzi kufuneka icocwe ubuncinane kanye ngonyaka.Ngaphandle koko, i-silt kunye nezinye izinto ezingcolileyo aziyi kugubungela kuphela i-tank, kodwa kunye neendonga zayo.Oku kuya kuvumela itanki ukuba isebenze njenge-incubator kunokuba ikhuphe ubushushu emoyeni.
Kutshanje bendikwifektri kwaye ubushushu beoyile kwi-stacker ibingama-350 degrees.Kwavela ukuba uxinzelelo lwalungalingani, i-valve yokunceda i-hydraulic accumulator manual yayivulekile, kwaye ioli yayihlala inikezelwa nge-flow regulator, eyenza i-hydraulic motor.Ikhonkco lokuthulula eliqhutywa yi-injini lisebenza kuphela ngamaxesha angama-5 ukuya kwali-10 ngexesha lokutshintsha kweeyure ezisi-8.
I-valve yempompo yempompo kunye nevalve yokunceda zibekwe ngokuchanekileyo, i-valve ye-manual ivaliwe, kwaye i-electrician de-energize i-valve ye-motor way, ivala ukuhamba nge-flow regulator.Xa esi sixhobo sajongwayo kwiiyure ezingama-24 kamva, iqondo lobushushu leoli lehla laya kutsho kwi-132 degrees Fahrenheit.Ngokuqinisekileyo, ioli ayiphumelelanga kwaye inkqubo kufuneka ihlanjululwe ukususa i-sludge kunye ne-varnish.Iyunithi nayo kufuneka izaliswe ngeoli entsha.
Zonke ezi ngxaki zenziwe ngokwenziwa.Abaphathi be-crank basekhaya bafakele imbuyekezo phezu kwevalve yokukhulula ukuvumela umthamo wempompo ubuyele kwindawo yoxinzelelo oluphezulu xa kungekho nto isebenzayo kwipaver.Kukho nabantu abangakwazi ukuvala ngokupheleleyo ivalve ye-manual, evumela ukuba ioli ibuyele kwitanki yoxinzelelo oluphezulu.Ukongezelela, inkqubo yayicwangciswe kakubi, ibangela ukuba ikhonkco isebenze ngokuqhubekayo xa ifuna ukuqaliswa kuphela xa umthwalo wawuza kususwa kwi-stacker.
Ngexesha elizayo xa unengxaki ye-thermal kwenye yeenkqubo zakho, khangela ioli equkuqelayo ukusuka kwinkqubo yoxinzelelo ephezulu ukuya kwengaphantsi.Apha ungafumana iingxaki.
