Njengecandelo eliphambili loxhulumaniso kwiinkqubo ze-hydraulic, i-hydraulic connectors 'umsebenzi ongundoqo kukuqinisekisa ukuhanjiswa okuthembekileyo nokusebenzayo kwe-hydraulic fluid (ngokuqhelekileyo ioli) phakathi kwemibhobho kunye namacandelo, ngelixa ugcina uxinzelelo lwenkqubo kunye nokuthintela ukuvuza. Umgaqo wabo wokusebenza ubandakanya iziphumo ze-synergistic yobuchwephesha bolwelo, itekhnoloji yokutywinwa kwezinto, kunye nolwakhiwo lomatshini. Olu hlalutyo lulandelayo lujolise ekubunjweni kwesakhiwo, iindlela zokutywinwa, kunye nokuphunyezwa kokusebenza phantsi kweemeko ezinamandla.
1. Ukubunjwa koLwakhiwo kunye neNdawo yokuSebenza okuSisiseko
Ulwakhiwo olusisiseko lwe-hydraulic connector ngokubanzi lunamacandelo amathathu: umzimba oyintloko (icandelo lokudibanisa), indibano yokutywina, kunye nesixhobo sokutshixa. Umzimba oyintloko unoxanduva lokudibanisa imigca ye-hydraulic (efana nemibhobho yentsimbi kunye nemibhobho) okanye izakhi ze-hydraulic (ezifana neepompo, iivalve, kunye neesilinda). Uyilo lwangaphakathi eludongeni kufuneka luhambelane nobubanzi kunye nokumila komjelo wolwelo. Icandelo lokutywina licandelo elingundoqo elisebenzayo, kwaye iifom eziqhelekileyo ziquka i-O{3}} amakhonkco (irabha okanye i-polyurethane), iigasket ezihlanganisiweyo (iindibaniselwano zetsimbi kunye nerabha), okanye iindawo eziqinileyo zokutywina (ezifana ne-conical/spherical surfaces). Indlela yokutshixa ikhusela kwaye inqande ukukhulula umdibaniso ngodibaniso olunemisonto (efana nemigangatho ye-NPT kunye ne-BSPP), izifakelo zokucinezela (ezifana ne-SAE J514 izifakelo zokucinezela), okanye{6}ukukhawuleza ukuqhagamshela iinzipho (ezifana{7}}noxinzelelo olukhawulezayo{8}okutshintsha izihlanganisi eziqhele ukusetyenziswa kumatshini wokwakha).
Ukususela kumbono wokusebenza, izixhumi ze-hydraulic kufuneka zihlangabezane neemfuno ezintathu ezisisiseko ngaxeshanye: okokuqala, misela indlela eqhubekayo yamanzi ukuze kuqinisekiswe ukuhamba kweoli okungathintekiyo; okwesibini, ukumelana noxinzelelo lwenkqubo yokusebenza (ngokuqhelekileyo i-10-50 MPa, kodwa idlula i-100 MPa kwiimeko ezinzima) ngaphandle kokuguqulwa kweplastiki okanye ukuphuka; kwaye okwesithathu, gcina uxinzelelo lwenkqubo ezinzileyo ngokuthintela iindlela zokuvuza zangaphakathi nangaphandle ngokusebenzisa icandelo lokutywinwa.
2. Inkqubo yokutywina: Ibhalansi eDynamic eqhutywa luxinzelelo
Ukusebenza kokutywinwa kokufakwa kwe-hydraulic ngundoqo womsebenzi wabo. Umgaqo wayo usekwe kwiindlela ezimbini "zoxinzelelo lwesiqu sakho{1}}nokuqina" kunye "nembuyekezo{2}}yangaphambili." Xa inkqubo ye-hydraulic ivuliwe, umbane uvelisa uxinzelelo lokuqala phantsi kwesenzo sempompo. Ngeli xesha, amandla oxinzelelo kwicandelo lokutywinwa ayanda njengoko uxinzelelo lukhuphuka. Umzekelo, i-O - iringi ixinzelelwe nge-radially, kwaye indawo yayo yoqhagamshelwano kunye noxinzelelo loqhagamshelwano lwanda ngaxeshanye, lugcwalisa izithuba ezincinci phakathi komzimba oyintloko kunye nesinxibelelanisi (njengemingxuma ebangelwa buburhabaxa bomphezulu). Kumatywina etywina (afana ne-74℃taper engile yofakelo lwemibhobho yehydraulic),{9}}i-oyile yoxinzelelo oluphezulu iphinda ibuyele umva kumphezulu ocociweyo, ityhale imiphezulu yokutywina isondelelane, idala isiphumo esihle sempendulo: "okukhona uphezulu uxinzelelo, kokukhona itywina iqina."
Kuyafaneleka ukuba uqaphele ukuba ukutywinwa akuthembeli kuphela kwizinto eziphathekayo.-uyilo locinezelo lwangaphambili lubalulekile. Umzekelo, O{3}}amakhonkco afuna i-15%-30% yoxinzelelo lomlinganiselo ngexesha lofakelo (ixabiso elithile lixhomekeke kubulukhuni berabha kunye nobushushu bokusebenza) ukuqinisekisa ukutywinwa kokuqala naphantsi koxinzelelo oluphantsi. Phantsi {{8}iimeko zoxinzelelo oluphezulu, icandelo lokutywina kufuneka lixhathise kwi-extrusion (umzekelo, ifayibha{9}}ifiber{9}}eyomeleziweyo ye-polyurethane O{11}}izangqa) kwaye imelane ne-corrosion yemidiya (umzekelo, i-fluoroelastomer ilungele i-phosphate ester hydraulic fluids). Ukungonelanga kwangaphambili{12}}kuxinzelelo{13}}kuvuza kuxinzelelo oluphantsi, ngelixa ucinezelo olugqithileyo lwangaphambili lunokubangela ukuguga okugqithisileyo kumphezulu wokutywina okanye kwenze ukudibanisa kunye nokuqhaqha kube nzima.
3. Uzinzo oluSebenzayo phantsi kweeMeko zokuSebenza eziDynamic
Kumsebenzi wokwenene, izihlanganisi zehydraulic kufuneka zimelane nokuguquguquka rhoqo koxinzelelo (ezifana noxinzelelo oluphezulu-i-spikes zoxinzelelo olubangelwa kukothuka kwehydraulic), utshintsho lobushushu (ukusebenza ngaphaya koluhlu olubanzi lobushushu obuyi -40℃ukuya +120℃), kunye nokungcangcazela koomatshini (okufana nokungcangcazela rhoqo koomatshini bokwakha). Ukujongana nale mingeni, umgaqo wayo wokusebenza ufezekisa uzinzo ngezi ndlela zilandelayo:
Okokuqala, uxinzelelo{0}}uyilo olufunxayo: Ephezulu{1}}iziqhagamshelo zesiphelo zihlala zibandakanya izakhiwo ezimanzi (ezifana negrooves okanye amagumbi e-buffer). Xa ukutshatyalaliswa kwe-hydraulic kwenzeka kwisistim, isakhiwo sokudambisa sandisa ixesha lokunyuka koxinzelelo kunye nokuthintela ukungaphumeleli kwetywina ngenxa yokugqithiswa kwexesha elifutshane. Umzekelo, ezinye{4}}iziqhagamshelo zemibhobho yoxinzelelo eziphezulu zinemijelo ejikelezayo yangaphakathi eyandisa indlela yokuhamba kwe-oyile ukunciphisa amandla othuko.
Okwesibini, imbuyekezo yokwandiswa kwe-thermal: Ukutshintsha kobushushu kunokubangela ukungafani kokwandiswa kwe-thermal kunye ne-contraction coefficients yezinto zokutywinwa kunye nezixhobo zetsimbi (umzekelo, irabha inokwandisa ngesantya esingaphezu kwe-10 amaxesha esinyithi kumaqondo aphezulu), enokuthi ijonge ukulayishwa kwangaphambili kwetywina. Ukulungisa oku, ezinye iziqhagamshelo zisebenzisa "umsesane wetywina odadayo" (ofana ne-O{2}}ulungiselelo lomsesane ogxadazayo) ukuvumela udibaniso lwetywina ukuba luhambe nge-axially phakathi koluhlu oluthile, luhlawulela ubushushu{3}}utshintsho lwedimensional eyenziweyo.
Okokugqibela, ucinezelo lokungcangcazela: Ulwa{0}}ukukhulula uyilo lwendlela yokutshixa ngundoqo. Umzekelo, amajoyinti anemisonto ahlala edityaniswa neewasha zasentwasahlobo okanye i-nylon locknuts, ezisebenzisa ukuxhathisa ukukhuhlana ukuthintela ukukhulula okubangelwa kukungcangcazela. Ufakelo locinezelo, kwelinye icala, luxhomekeke ekudibaneni komatshini we-ferrule kudonga lombhobho (kunokuba nje ukunyanzeliswa kwentambo) ukugcina ukuthembeka koqhagamshelwano naphantsi kokungcangcazela ixesha elide.
Ukuqukumbela
Umgaqo wokusebenza we-hydraulic fittings ngokuyimfuneko yindibaniselwano "yokwakhiwa kwendlela yamanzi," "ukutywinwa koxinzelelo loxinzelelo," kunye "nokulungelelanisa okuguquguqukayo kwiimeko zokusebenza." Ukusuka kwitywina elimileyo langaphambili ukuya kuxinzelelo oluguqukayo-lobushushu{2}}intshukumo yentshukumo kaninzi{3}}kudityaniso lwendawo, uyilo lwazo kufuneka lubambelele ngokungqongqo kwimithetho yobuxhakaxhaka bolwelo kunye nemigaqo yenzululwazi yemathiriyeli. Njengoko iinkqubo zehydraulic ziguqukela kuxinzelelo oluphezulu (ezifana ne-Ultra{{5}phezulu{6}}uxinzelelo lwezicelo ezidlula i-80 MPa) kunye nobukrelekrele obukhulu (njengezinto ezifakelwe ezihlakaniphileyo ezinezivamvo zoxinzelelo ezihlanganisiweyo), imigaqo yokusebenza yokufakelwa kwe-hydraulic yexesha elizayo iya kudibanisa ngakumbi ubuchwephesha bokuvelisa kunye neemfuno zolawulo lomtya wokuhlangabezana ngakumbi.
