Uma uthola izingxenye ze-hydraulic zemishini yezimboni noma imishini ehambayo, inombolo yemodeli egxishwe ku-pump ingaphezu nje kwezinhlanganisela ezingahleliwe zezinhlamvu nezinombolo. Isebenza njengolimi oluncane lwezobuchwepheshe oludlulisa imininingwane ebalulekile njengokushintsha indawo, isilinganiso somfutho, indlela yokujikeleza, nokuhlelwa kwe-port. Ukwazi ubuciko bokuqonda imininingwane yezobuchwepheshe ye-hydraulic pump ngokuhumusha ikhodi yemodeli kunganciphisa kakhulu amaphutha ekuthengeni, kuthuthukise ukuhambisana kwesistimu, futhi kwehlise izindleko zokulungisa. Ochwepheshe bezobunjiniyela nabathengi abakwazi ukuhumusha lezi zikhodi ngokushesha bathola inzuzo yokuncintisana, ikakhulukazi lapho besebenzisana nabahlinzeki bamazwe ngamazwe noma izingxenye ezishintshwayo. Lo mhlahlandlela uzokuhambisa emqondweni wezakhiwo zezinombolo zemodeli, uchaze izinkambiso ezijwayelekile zokubhala ikhodi ezisetshenziswa abakhiqizi abahamba phambili, futhi unikeze izindlela ezenzakalayo zokukhetha i-pump efanele isicelo sakho. Ekupheleni kwalesi sihloko, uzobe usuhlomile ukufunda izinombolo zemodeli ye-hydraulic pump ngokuzethemba futhi ugweme ukungahambisani okubizayo ezinhlelweni zakho ze-hydraulic.

Izinombolo zemodeli zamaphampu e-hydraulic ngokuvamile zakhiwa ngezigaba ezimbalwa ezihlukene, ngasinye simelela isici esithile sobuchwepheshe bephampu. Ifomethi ejwayelekile ingafana ne-GP-20-25-R-P, lapho ingxenye yokuqala ikhombisa uchungechunge noma umndeni womkhiqizo, eyesibili ikhombisa ukugudluzwa ngamasentimitha ayi-cubic nge-revolution ngayinye, kanti eyesithathu icacisa isilinganiso somfutho oqhubekayo omkhulu nge-bar. Izinhlamvu ezilandelayo ngokuvamile zikhombisa indlela yokujikeleza—ngokwewashi noma ngokuphambene newashi—kanye nokuhlelwa kwezimbobo, njengezimbobo eziseceleni uma kuqhathaniswa nezimbobo ezingemuva. Ukuqonda lesi sakhiwo esihlukanisiwe kubalulekile ekuchazeni imininingwane yamaphampu e-hydraulic ngoba kukuvumela ukuthi uhlukanise ipharamitha ngayinye futhi uyiqinisekise ngokumelene nezidingo zohlelo lwakho. Nakuba ukuhleleka okuqondile kwezigaba kuhluka phakathi kwabakhiqizi, umgomo oyisisekelo uhlala ungaguquki: uhlamvu ngalunye lunencazelo, futhi ukweqa ngisho nedijithi eyodwa kungaholela ekukhetheni iyunithi engahambisani. Ngenxa yalesi sizathu, njalo thola idathashethi noma ikhathalogi esemthethweni yomkhiqizi lapho uqala ukuhumusha ikhodi yemodeli okokuqala.

Inombolo yemodeli eklanywe kahle ngokuvamile ihlanganisa umkhombandlela wochungechunge, ohlanganisa amaphampu ngokwesizukulwane somklamo noma inkundla yobuchwepheshe. Okulandelayo ukususwa, okuvame ukuvezwa nge-cc/rev (amasentimitha ayisikwele ngokujikeleza) kumaphampu wemethrikhi noma i-in³/rev yemiklamo esekelwe ku-intshi. Imininingwane yokulinganisa kwengcindezi iyalandela, ngezinye izikhathi ihlukaniswe ibe amanani amakhulu aqhubekayo nawesikhashana. Ukuya kwesokudla kokujikeleza ngokuvamile kuboniswa ngohlamvu olulodwa olufana no-R (kwesokudla) noma u-L (kwesokhohlo) uma ubuka ukusuka ekugcineni kwe-shaft. Amakhodi okucushwa kwezimbobo acacisa amazinga wentambo—i-SAE, i-BSP, noma i-NPT—kanye nendawo yezimbobo nosayizi. Abakhiqizi abambalwa bafaka nohlobo lwe-shaft, isitayela se-flange yokufaka, kanye nezinto zokuvala ngqo emgqeni wemodeli. Ngenxa yokuthi le migaqo ithinta ngqo indlela iphampu ehlangana ngayo nomjikelezo wakho we-hydraulic, ukuhlola inkambu ngayinye ngokumelene nohlelo lwakho lusebenzisa isinyathelo esibalulekile enqubweni yokuthenga.

Ngaphezu kwesakhiwo esingaphezulu senombolo yemodeli, kunezici zobuchwepheshe ezichaza ngempela ukusebenza kwepompo. Ukususwa kwamanzi, isibonelo, kunquma izinga lokugeleza elingokwethiyori ngesivinini esithile sokujikeleza: ipompo ene-25 cc/rev esebenza nge-1800 RPM iletha cishe amalitha angu-45 ngomzuzu ngaphambi kokulahlekelwa ukusebenza kahle kwevolumu. Izinga lokucindezela liza ngezinhlobo ezimbili—okuqhubekayo nokungapheli—futhi ukwehluleka ukuhlonipha umkhawulo wokungapheli kungaholela ekuhlulekeni kwesivalo ngaphambi kwesikhathi noma ukuqhekeka kwekhava. Isivinini sokujikeleza singenye ipharamitha ebalulekile; ukusebenzisa ipompo ngaphansi kwesivinini sayo esincane kungabangela ukungagcini kahle kwamafutha ezingxenyeni zangaphakathi, kuyilapho ukweqa isivinini esiphezulu kungabangela umonakalo we-cavitation kanye ne-bearing. Usayizi wamachweba kanye nezinhlobo zentambo (i-SAE O-ring boss, i-BSPP, noma i-NPT) kufanele zihambisane ngqo nezinto zokuhlanganisa, njengoba izintambo ezingahambisani ziwumthombo ovamile wokuvuza ezinhlelweni ze-hydraulic. Ukuhlelwa kwama-shaft, okuhlanganisa ubukhulu be-keyway kanye namazinga e-spline, nakho kubalulekile ngoba kulawula ukuxhumana phakathi kwepompo kanye ne-prime mover. Ekugcineni, ama-flange okufaka avame ukulandela amazinga e-SAE noma e-ISO, futhi iphethini ye-flange engalungile ingenza ukufakwa kungenzeki ngokomzimba ngaphandle kwama-adaptha. Ngayinye yalezi zinto ivame ukufakwa kwinombolo yemodeli, okwenza ukuhlehlisa ngendlela ehlelekile kube yikhono elibaluleke kakhulu kunoma ubani obandakanyeka ekukhetheni ipompo ye-hydraulic.

Ukukhishwa kungumthombo obaluleke kakhulu kunazo zonke ngoba kunquma ngqo ukuthi iphampu ihambisa uketshezi olungakanani ngomjikelezo ngamunye. Ephasimini yephampu, ukukhishwa kungumsebenzi wobubanzi bombhobho, ubude besitrobhu, kanye nenani lamaphasitoni, konke okungaguquki kuhlobo oluthile lwemodeli. Izinga lokugeleza libalwa ngokuphindaphinda ukukhishwa ngesivinini sokujikeleza nokulungisa ukusebenza kahle kwevolumu, okuvame ukusuka ku-85% kuya ku-98% kuye ngomklamo wephampu nezimo zokusebenza. Uma uhlukanisa ikhodi yemodeli, qaphela njalo ukuthi inani lokukhishwa livezwa nge-cc/rev noma in³/rev, ngoba ukudida lokhu kungaholela ephasimini engenamandla noma enkulu kakhulu kusekethe yakho. Abakhiqizi abaningi bafaka nekhodi yokulawula ukugeleza, njengesici sokunxeshezelwa kwengcindezi noma ukuzwa umthwalo, okuthonya indlela ukugeleza okuziphatha ngayo ngaphansi komthwalo oshintshashintshayo. Ukuqonda lezi zinto ezincane kukuvumela ukuthi ufanise iphampu nezidingo eziqondile zokugeleza kwesistimu yakho kunokuthembela ekuqageleni.

Izinga lokucindezela livame ukukhonjiswa enombolweni yemodeli njengenani elilandelwa inkomba yeyunithi, njengo-25 okusho u-250 bar noma u-36 okusho u-3600 psi. Izinga lokucindezela okuqhubekayo lichaza umkhawulo wokucindezela ophezulu umshini ongawusebenzisa ngaphansi kwezimo ezijwayelekile zokusebenza, kuyilapho izinga eliphakathi nendawo lihlanganisa izikhathi ezimfushane zokucindezela ezingenzeka ngesikhathi sokushintsha kwesistimu. Ukukhetha umshini onezinga elinganele lokucindezela okuqhubekayo kuzoholela ekugugulekeni okusheshayo, ukuncipha kokusebenza kahle, nokugcina kuhluleke, ikakhulukazi ezinhlelweni ezidinga amandla amakhulu njengokubumba nge-injection noma izinto zokwakha ezisindayo. Ngokuphambene, ukucacisa ngokweqile izinga lokucindezela kwengeza izindleko ezingadingekile futhi kunganciphisa ukusebenza kahle kwevolumu. Ezinye izinombolo zemodeli ezithuthukile zihlanganisa nekhodi yohlobo lokulawula ukucindezela—ukususwa okungaguquki, ukunxephezela ukucindezela, noma ukuzwa umthwalo—okuthinta indlela umshini ophendula ngayo ezidingweni zesistimu. Lapho uhlola imininingwane yomshini we-hydraulic, hlala ubheka izinkodi zokucindezela ngemininingwane yobuchwepheshe yomkhiqizi ukuze uqinisekise ukuthi amandla okucindezela omshini ahambisana nokuhlelwa kwe-valve yokukhulula kanye nesimo somthwalo ophezulu wesekethe yakho.

Nakuba umqondo ojwayelekile wezinombolo zemodeli uwusizo, umkhiqizi ngamunye wamaphampu e-hydraulic usebenzisa izimiso zawo zokubhala amakhodi ezibonisa umlando wawo wobunjiniyela kanye nesakhiwo somkhiqizo. Isibonelo, i-Rexroth isebenzisa uhlelo lwe-alphanumeric lapho izinhlamvu zokuqala zikhomba uhlobo lwephampu (isb., i-A10VO yephampu ye-swashplate axial piston), kulandele usayizi, indlela yokulawula, kanye nendlela yokujikeleza. Amaphampu e-hydraulic akwaParker avame ukufaka ikhodi yochungechunge efana ne-P1 noma i-P2, bese kuba ukugudluzwa ngama-cc/rev, kanye nesijobelelo esikhombisa izinketho ze-shaft nezimbobo. Izinombolo zemodeli zakwa-Eaton zivame ukufaka usayizi we-frame, njenge-5420 noma i-72400, kanye nezinhlamvu ezichaza ukugudluzwa kanye nezici zokulungisa ingcindezi. Uma kutholwa emhlabeni wonke, ukuhlanganisa izinombolo zemodeli kusetshenziswa amakhathalogi abakhiqizi kuwumkhuba obalulekile, ngoba ushintsho oluncane lwencwadi lungakhomba ububanzi be-shaft obuhlukile noma impahla yokugwinya. Abahlinzeki abaningi, okuhlanganisa i-Guangdong MKS Hydraulic Co., Ltd., bahlinzeka ngemihlahlandlela enemininingwane yokuhlanganisa.Imikhiqizo ikhasi, elingakusiza ukuthi uhlonze amamodeli afanayo avela emikhiqizweni ehlukene. Uma uhlangabezana nekhodi ongayazi, indlela ephephe kakhulu ukubheka ikhathalogi yoqobo noma uxhumane nosekelo lobuchwepheshe kunokuthembela enkumbulweni noma ekucabangeni ukuthi ziyafana.

Ama-pump akwa-Rexroth ngokuvamile aqala ngenhlanganisela yohlamvu nedijithali ekhomba umndeni wepump, njenge-A4VSO epompa ye-axial piston enokushintsha-kusebenza emjikelezweni ovulekile. Izinombolo ezilandelayo zikhomba umfutho oqondiwe kanye nokushintsha-kusebenza, kulandele amakhodi ohlobo lokulawula afana ne-DR (ukulawula umfutho) noma i-DFR (ukulawula umfutho nokugeleza). Uchungechunge luka-Parker F11, ngokuphambene, lusebenzisa umklamo wokushintsha-kusebenza okungaguquki futhi lufaka ikhodi yokushintsha-kusebenza ngqo enombolweni yemodeli, kuyilapho izijobelelo zikhomba ukuma kwembobo nohlobo lwe-shaft. Uchungechunge luka-Eaton 420 lulandela umqondo ohluke ngokuphelele, ngezinombolo zemodeli ezigcizelela usayizi wozimele kanye nobubanzi bokushintsha-kusebenza kunokukhetha okuhlukile kokulawula. Lokhu kwehluka kusho ukuthi umuntu onolwazi ngamakhodi akwa-Rexroth akakwazi ukuhumusha inombolo ka-Parker ngokuzenzakalelayo ngaphandle kokufunda ikhathalogi ehambisanayo. Ngenhlanhla, ochwepheshe abaningi be-hydraulic bashicilela amathebula okuguqula, futhiIzindaba ingxenye yamawebhusayithi omthengisi ivamise ukuqukatha izindatshana zobuchwepheshe ezichaza ukuthi ungakwazi kanjani ukuhumusha izinkambiso eziqondene nomkhiqizo othile. Ukutshala isikhathi ekufundeni lezi zindlela kuzuzisa uma uthola amaphampu okushintsha noma wandisa uhlu lwempahla yakho yohlelo lwe-hydraulic.

Umongo wokusebenza kwepompo ye-hydraulic unomthelela omkhulu ekutheni yimiphi imingcele yemodeli efanele ukunakwa kakhulu. Ezinhlelweni ezihambayo ezifana nemishini yokumba noma imishini yezolimo, ipompo kufanele ibekezelele imithwalo ephezulu yokushaqeka, ukushintshashintsha kwezinga lokushisa okukhulu, kanye nemijikelezo evamile yokuqala nokuma kunemishini yezimboni emile. Lokhu kusho ukuthi isilinganiso somfutho, indlela yokufaka, kanye nokuhambisana noketshezi kubaluleke kakhulu lapho kuhunyushwa izinombolo zemodeli yezinhlelo ze-hydraulic ezihambayo. Izinhlelo zezimboni, ngakolunye uhlangothi, zivame ukubeka phambili ukusebenza kahle kwevolumu, izinga lomsindo, kanye namandla okulawula amahle, okufakwe kumphumela wohlobo lokulawula lwepompo kanye nekhodi yokugudluzwa. Imininingwane yokusebenza efana nokusebenza kahle kwevolumu ayivamisile ukukhonjiswa ngqo enombolweni yemodeli kodwa ingacatshangwa kusukela ochungechungeni lwepompo kanye nobubanzi bokugudluzwa—amaphompo amakhulu emndenini ngokuvamile athola ukusebenza kahle okuphezulu. Izinga lomsindo ngezinye izikhathi likhonjiswa yikhodi yohlamvu ehambisana nomklamo othile wokunciphisa umsindo noma wezindlu. Ukuhambisana noketshezi, okuhlanganisa uhlobo lwamafutha e-hydraulic kanye namazinga okungcola amukelekayo, kungase kubhekiselwe kukho ngokungaqondile ngezinhlamvu zempahla yokugcina ezifakwe ochungechungeni lwemodeli. Ukunaka le mininingwane eqhutshwa ukusetshenziswa kuqinisekisa ukuthi ipompo oyikhethayo izosebenza ngokuthembekile endaweni yayo ehlosiwe kunokuba iphoqelelwe endimeni ebingaklanyelwe yona.

Izinombolo zemodeli ezinamaqembu athile ezijobelelo nezandulela zingembula izimfanelo ezibalulekile zekhwalithi ezithinta ukwethembeka kwesikhathi eside. Izinga lezinto zokwakha zamahousing, ama-piston, namapuleti e-valve zingakhonjiswa ngezinhlamvu ezifana no-G okusho i-ductile iron noma u-S okusho insimbi, kuyilapho amakhodi wezinto zokuvala afana no-V okusho i-Viton noma u-N okusho i-nitrile enza ukuthi kuhambisane nezinhlobo ezahlukene zoketshezi. Izitifiketi ezifana ne-ATEX yezindawo ezinokuqhuma noma uphawu lwe-CE lokuhambisana nemithetho yaseYurophu kwesinye isikhathi kufakwa njengamakhodi ahlukene ngemva kwenombolo eyinhloko yemodeli. Uma uthola umkhiqizo kumkhiqizi othembekile njenge-Guangdong MKS Hydraulic Co., Ltd., ungakulindela ukuthi izinombolo zemodeli ezisezinto zaboAmaphampu Asebenza Ngamanzi ikhasi likhombisa ngokucacile lezi zinkomba zekhwalithi, okwenza kube lula ukuqhathanisa izinketho. Ukwengeza, amazinga okuhlola angaphakathi—njengokuhlola ukucindezela kobufakazi noma izidingo zokugijima okuqhubekayo—angafakwa emgqeni wemodeli yemikhiqizo ethile. Ukuqonda lezi zimpawu zekhwalithi kusiza amaqembu okuthenga ukugwema amayunithi asezingeni eliphansi angonga imali ekuqaleni kodwa aholele ekwehleni okukhulu nasezindlekweni zokulungisa emjikelezweni wokuphila kwemishini.

Noma unolwazi oluqinile ngomqondo wezinombolo zemodeli, izinyathelo zokuhlonza ezingokoqobo zihlala zibalulekile ukuze ugweme amaphutha. Hlala uqala ngokuhlola i-nameplate ebonakalayo noma ukuqoshwa kwe-laser empompini uqobo, njengoba upende, ukungcola, noma ukugqwala kungafihla izinhlamvu. Thatha isithombe esicacile bese usiqhathanisa nekhathalogi esemthethweni yomkhiqizi kunokuthembela kuzinqolobane zedatha zangaphandle ezingase zibe namaphutha. Uma imibhalo yokuqala ingekho, amathuluzi okusesha aku-inthanethi kanye ne-xhumanaIkhasi lamawebhusayithi womhlinzeki lingakuxhumanisa namathimba okusekela kwezobuchwepheshe angakwazi ukuhumusha inombolo yemodeli ngokusekelwe ezithombeni nasezilinganisweni. Qhathanisa inombolo yemodeli nemithombo eminingi, kuhlanganise newebhusayithi esemthethweni yomkhiqizo, futhi uqinisekise ukuthi isilinganiso sokugudluka nokucindezela siyahambisana nezidingo zohlelo lwakho. Uma ungabaza, linganisa ububanzi bomgodi we-shaft, iphethini yamabholithi okufaka, nosayizi wentambo yembobo ngqo, njengoba lezi zilinganiso zomzimba zinikeza ukuhlola okuvikelekile ngokumelene namakhodi ezinhlamvu. Bhala konke okutholakele ngefomethi ehlelekile ukuze imijikelezo ezayo yokuthenga ikwazi ukubhekisela kudatha efanayo eqinisekisiwe.

Iphutha elivamile ukudidanisa izilinganiso zomfutho oqhubekayo nezomfutho ophazamisekayo, okungaholela ekucaciseni iphampu ehluleka ngaphansi kwemithwalo evamile yokusebenza. Elinye iphutha elivamile lihlanganisa ukufunda kabi amakhodi wesiqondiso sokujikeleza: iphampu emakwe ngo-R ingase ibe ukujikeleza kwesokudla uma ibukwa ekugcineni kwe-shaft, kodwa abanye abakhiqizi bachaza ukujikeleza besuka ekugcineni okuphambene, okudala ukuhlehla okuyingozi. Izindinganiso zentambo yezimbobo nazo ziyisicupho—i-SAE O-ring boss ne-BSPP threads zibukeka zifana kodwa azishintsheleki, futhi ukuzihlanganisa kungadala ukuvuza okunzima ukukuthola. Amayunithi okususa nawo adala ukudideka; isibonelo, i-25 cc/rev ayifani ne-25 in³/rev, futhi ukubala okungalungile kungaholela ephampini ehlinzeka ukugeleza okunguhhafu noma okuphindwe kabili kunalokho okudingekayo. Ukuze ugweme lezi zicupho, hlala uxhumanaIkhaya ikhasi noma imibhalo yomkhiqizo yomthengisi ukuze uthole amashidi acacile okucaciswa. Ukuthuthukisa uhlu lokuhlola oluhlelekile oluhlanganisa ukuqinisekisa ukuzungezisa, ukuqinisekisa uhlobo lwentambo, kanye nokuhlola umfutho kuzonciphisa kakhulu ingozi yokukhetha iphampu engafanele.

Ukuhumusha izinombolo zemodeli yepompo ye-hydraulic kuyikhono elihlanganisa ulwazi lobuchwepheshe, ukunaka imininingwane, kanye nokujwayela izimiso zabakhiqizi. Ngokuqonda ukwakheka okuhlukanisiwe kwezinombolo zemodeli—uchungechunge, ukususwa kwamanzi, umfutho, ukuzungeza, ukuhlelwa kwembobo, kanye nohlobo lweshafi—ungakwazi ukukhipha imingcele ebalulekile edingekayo ukuze ufanise ipompo nohlelo lwakho. Sihambe inqubo yokuhumusha ukususwa kwamanzi kanye nezinga lokugeleza, amazinga omfutho oqhubekayo nowe-intermittent, isivinini sokuzungeza kanye nesiqondiso, usayizi wembobo kanye namazinga wentambo, kanye nokuhlelwa kweshafi nokufakwa. Izibonelo eziqondene nomkhiqizi ezivela ku-Rexroth, Parker, kanye ne-Eaton zibonise ukuthi izimiso zomkhiqizo zihluka kanjani nokuthi kungani ukuhlanganisa nezincwadi ezisemthethweni kubalulekile.
