Uma kukhulunywa ngokuklama, ukugcina, noma ukuthuthukisa uhlelo lwe-hydraulic, imisebenzi embalwa ebaluleke kangaka—futhi evame ukungaqondwa kahle—njengokukhetha iphampu efanele. Iphampu iyinhliziyo yanoma yimuphi umjikelezo we-hydraulic, enomsebenzi wokuguqula amandla emishini abe ukugeleza nokucindezela koketshezi. Nokho, inqubo yokukhetha iyunithi efanele ivame ukuzwakala inzima ngenxa yezintambo eziminyene zezinhlamvu nezinombolo ezakha amakhodi emodeli yamaphampu e-hydraulic. Lawa makhodi awawona nje amaqhinga; awulimi olumfishane oluhlanganisa konke kusukela ekushintsheni kwevolumu nokulinganiselwa kwengcindezi kuya ekuzungezeni nokuhlelwa kwamachweba. Kubaphathi bokuthenga, onjiniyela bokugcina, nabaklami bezinhlelo, ukufunda ukufunda lawa makhodi kuyikhono elibalulekile elonga isikhathi, linciphisa amaphutha abizayo, futhi liqinisekise ukusebenza kahle kohlelo. Lo mhlahlandlela ophelele uzokuhambisa kuzo zonke izici zemininingwane yobuchwepheshe yamaphampu e-hydraulic, kusukela ekuhumusheni izinombolo zamamodeli ezinama-alphanumeric kuya ekusebenziseni leyo mininingwane ezimweni zangempela, ekunike amandla okwenza izinqumo zokuthenga ezinolwazi ngokuqiniseka.

Ikhodi yemodeli yepompo ye-hydraulic ayisiyona nje inombolo yengxenye elula—iyindlela emfishane evamile ekhombisa ubunikazi namandla epompo. Abakhiqizi baklama lezi zikhodi ukuze badlulise imininingwane ebalulekile njengokugudluzwa ngokujikeleza ngakunye, izinga lokucindezela eliphezulu, indlela yokujikeleza kwe-shaft, isitayela se-flange yokufaka, kanye nezinhlobo zentambo yokufaka. Isibonelo, ikhodi efana "PVP-20-40-2S-10" itshela umuntu onolwazi ngokushesha ukuthi ipompo ingeyesigaba esithile, inokugudluzwa okungu-40 cc ngokujikeleza ngakunye, futhi inesakhiwo esithile se-shaft nokufaka. Ngaphandle kwekhono lokuhumusha lezi zikhodi, umthengi ubeka engcupheni yoku-oda ipompo ezungeza ngendlela engafanele noma engenawo amandla okucindezela adingekayo kusetshenziswa. Ezimbonini lapho isikhathi sokungasebenzi sibiza izinkulungwane zamadola ngehora, ukuhumusha kabi ikhodi yemodeli kungaholela ekubuyiselweni okubizayo, amaphrojekthi abambezelekile, ngisho nokulimala kwesistimu. Ukuqonda lezi zikhodi futhi kunika amandla onjiniyela ukuthi babheke izinto zokushintsha ezihambisanayo ezivela emikhiqizweni ehlukene, ikhono elibaluleke kakhulu lapho kutholwa izingxenye ze-aftermarket noma ezinye. Kunoma yimuphi uchwepheshe obandakanyeka ekuthengeni noma ekulungiseni izinhlelo ze-hydraulic, ukwazi ikhodi yemodeli akukona okuzithandela—kuyikhono eliyisisekelo elithinta ngqo ukusebenza kahle nokulawula izindleko.

Nakuba izinhlobo zamakhodi wamamodeli zihluka phakathi kwabakhiqizi, izinombolo zamamodeli wamaphampu amaningi ezihydraulic zilandela ukwakheka okunengqondo okuhlanganiswe izingxenye ezihlukene. Ingxenye yokuqala ngokuvamile ikhombisa uchungechunge noma umndeni wepompu, ikhomba uhlobo olujwayelekile lomklamo—njengepompu yamagiya ene-fixed displacement, ipompu ye-piston ene-variable displacement, noma ipompu ye-vane. Ingxenye yesibili cishe njalo ikhombisa i-geometric displacement, evame ukuvezwa ngama-cubic centimeters ngokujikeleza (cc/rev) noma ama-cubic inches ngokujikeleza. Lena inani elibaluleke kakhulu ekhodini ngoba linquma izinga lokugeleza ngesivinini esithile se-shaft. Ingxenye yesithathu ngokuvamile icacisa isilinganiso somfutho, esingavezwa njengomfutho ojwayelekile noma umfutho omkhulu wesikhashana. Izingxenye ezilandelayo zihlanganisa isiqondiso sokujikeleza—ngokwewashi noma ngokuphambene newashi uma ubuka ukusuka ekugcineni kwe-shaft—ukuhlelwa kwe-flange yokufaka, uhlobo nosayizi wentambo yembobo, isitayela se-shaft, kanye nezinto zokuvala. Isibonelo, ikhodi efana "A10VO-45-DFR-1X-R" ihlukaniswa kanje: "A10VO" ikhombisa uchungechunge lwepompu ye-axial piston, "45" isho i-displacement engu-45 cc/rev, "DFR" ikhombisa ukulawula okunxephezela umfutho ngokuthwala umthwalo, "1X" isizukulwane somklamo, kanti "R" isho ukujikeleza ngokwewashi. Ngokufunda lezi zingxenye, uchwepheshe we-hydraulic angakwazi ngokushesha ukunquma ukuthi ipompu izohambisana yini nohlelo olukhona ngaphandle kokuvula idatha. Le ndlela ehlelekile yokuhumusha ikhodi iyikhono elithuthukiswa ngokuzijwayeza, kodwa nabaqalayo bangafunda ngokushesha izimiso ezivame kakhulu zezingxenye ezisetshenziswa embonini.

Yize noma ngabe umkhiqizi ngamunye usebenzisa uhlelo lwawo lwekhodi, kunezindlela ezithile eziphindaphindeka emkhakheni we-hydraulic. Izinombolo zokugudluka zivame ukubekwa endaweni efanayo ngaphakathi kwekhodi, ngokuvamile ngemuva nje komkhombisi wohlobo. Izinga lokucindezela lingabhalwa ngezinhlamvu ezihambisana nezinga elithile lokucindezela—ngokwesibonelo, "H" ikhombisa ukucindezela okuphezulu kanti "L" ikhombisa ukucindezela okuphansi. Ukuqondiswa kokujikeleza kuvame ukukhonjiswa ngo-"R" ukusho ukujikeleza ngokwewashi kanye no-"L" ukusho ukuphambana newashi, nakuba eminye imikhiqizo isebenzisa "RH" kanye "LH". Amakhodi e-flange yokufaka alandela izindinganiso ezifana ne-SAE-A, SAE-B, noma i-ISO 3019, futhi lezi zivame ukumelwa ngohlamvu olulodwa noma inombolo emgqeni wekhodi. Izinkomba zentambo yezimbobo zingafaka u-"N" we-NPT, "S" we-SAE straight thread, noma "B" we-BSPP. Ukwakheka kwesiphetho se-shaft kuvame ukubhalwa ngezinhlamvu ezifana no-"S" we-splined, "K" we-keyed, noma "P" we-parallel key. Ukuqonda lezi zinto ezijwayelekile kuvumela umthengi ukuthi ahlole ngokushesha ukuthi ingabe iphampu evela kumkhiqizi othile ingasebenza njengokufakwa esikhundleni kwenye imikhiqizo, okusiza kakhulu lapho kutholwa kubathengisi abakhethekile. Ngokwesibonelo, umthengi obhekaIphampu Yepiston ikhasi elivela kumkhiqizi ohlonishwayo njenge-Guangdong MKS Hydraulic Co., Ltd. lingasebenzisa ulwazi lwekhodi yemodeli ukuze liqhathanise izimiso ezihlukene emikhiqizweni ehlukene futhi likhethe iyunithi eqondile edingekayo kumjikelezo wayo we-hydraulic.

Ngaphezu kwekhodi yemodeli, wonke umshini wokumpompa we-hydraulic uchazwa ngezilinganiso ezilinganisekayo zobuchwepheshe ezinquma ukufaneleka kwawo emsebenzini othile. Ukususwa, okukalwa ngamasentimitha e-cubic ngokujikeleza (cc/rev) noma ama-inch e-cubic ngokujikeleza (in³/rev), umthamo woketshezi umshini awuhambisa ngokujikeleza ngakunye kweshaft futhi unquma ngqo izinga lokugeleza ngesivinini esithile. Isilinganiso somfutho ngokuvamile sihlukaniswa ngamanani amabili: umfutho oqhubekayo olinganiselwe—umfutho omkhulu umshini ongawusekela ngaphansi kwezimo ezijwayelekile zokusebenza—kanye nomfutho ophakeme noma wesikhashana, okuwumfutho omkhulu ovunyelwe izikhathi ezimfushane ngaphandle kokulimaza umshini. Isilinganiso sesivinini, esivezwa ngokujikeleza ngomzuzu (RPM), sikhombisa ububanzi besivinini seshaft esivunyelwe; ukusebenza ngaphandle kwalobu bubanzi kungabangela i-cavitation, ukuguga okweqile, noma ukwehluleka okuphelele komshini. Ukusebenza kahle kuyisilinganiso esihlanganisiwe esihlanganisa kokubili ukusebenza kahle kwevolumu—ukuthi umshini uhambisa kanjani ukugeleza okucatshangwayo uma kuqhathaniswa nokugeleza kwangempela—kanye nokusebenza kahle kwemishini, okukala ukuthi ingakanani i-torque yokufaka eguqulwa ibe amandla e-hydraulic. Izidingo zamandla, ezivame ukuvezwa ngama-kilowatt noma amandla ehhashi, zichaza amandla okufaka adingekayo kumshini oyinhloko ukuze ushayele umshini wokumpompa ngaphansi kwezimo ezishiwo zomfutho nokugeleza. Isibonelo, umshini wokumpompa we-piston onokususwa okungu-45 cc/rev osebenza ngo-1800 RPM kanye no-250 bar uzodinga amandla okufaka angaba ngu-37 kW. Ukuqonda lezi zilinganiso ngokuhlangana kubalulekile ngoba zincike komunye nomunye: ukukhulisa umfutho kunciphisa ukusebenza kahle kwevolumu, futhi ukusebenza emikhawulweni ephezulu yomibili isivinini nomfutho kancane kancane kungafinyeza impilo yomshini. Noma yimuphi uchwepheshe obandakanyeka ekwakhiweni kohlelo lwe-hydraulic kufanele akwazi ukubala amazinga okugeleza, izidingo zamandla, kanye nokulahleka kokusebenza kahle esebenzisa lezi zilinganiso eziyisisekelo.

Ukusebenza kwangempela kwepompo ye-hydraulic ngaphansi kwezimo zokusebenza kutholakala ngezici zayo zokusebenza, ezingaphezu kwemingcele emisiwe ebhalwe ephepheni ledatha. Ukusebenza kahle kwe-volumetric, okuvame ukuvezwa njengephesenti, kukhombisa ukuthi ingakanani indawo yokuhambisa ethiyori etholakala njengokugeleza okuwusizo. Emazingeni aphansi omfutho, ipompo ingafinyelela ukusebenza kahle kwe-volumetric okungu-95–98%, kodwa njengoba umfutho ukhuphuka, ukuvuza kwangaphakathi ezikhaleni kuyanda futhi ukusebenza kahle kuyehla. Ukusebenza kahle kwemishini, okubala ukulahlekelwa kokungqubuzana kuma-bearing, izivalo, nezindawo zokuthintana zangaphakathi, ngokuvamile kusukela ku-85% kuya ku-95% emishinini eklanywe kahle. Ukusebenza kahle okuphelele kwepompo kungumkhiqizo wokusebenza kahle kwe-volumetric nokwemishini, futhi kuyisilinganiso sangempela sokuthi amandla okufaka angakanani aguqulwa abe umphumela we-hydraulic osebenzayo. Amajika okugeleza uma kuqhathaniswa nomfutho ayithuluzi elibaluleke kakhulu le-graphical lokuqonda ukusebenza kwepompo: akhombisa ukuthi ukugeleza okulethwayo kuncipha kanjani njengoba umfutho wesistimu ukhuphuka, futhi ukwakheka kwala majika kuveza izici zokuvuza kwangaphakathi kwepompo kanye nekhwalithi yomklamo. Amazinga omsindo, akalwa nge-decibel (dBA), angomunye umcabango obalulekile wokusebenza, ikakhulukazi ezindaweni ezingaphakathi noma ezinomsindo ezithintekayo njengezimboni zokukhiqiza noma imikhumbi yasolwandle. Amaphompo e-piston avame ukukhiqiza amazinga omsindo aphezulu kunamaphompo e-gear ngenxa yokuguquguquka komfutho okungokwemvelo emklamweni wawo, kodwa imiklamo yesimanje enesikhathi esilungisiwe nezici zokudambisa inganciphisa kakhulu umphumela womsindo. Izici zokukhuphuka kwezinga lokushisa nazo zibalulekile, njengoba ukukhiqizwa kokushisa okweqile kukhombisa ukusebenza kahle okuphansi futhi kungasheshise ukuwohloka koketshezi. Ngokufunda lezi zici zokusebenza, umthengi angabikezela ukuthi ipompo izoziphatha kanjani ohlelweni lwayo oluthile lwe-hydraulic, okuvumela ukuklanywa kwesistimu okunembe kakhudlwana kanye nokusebenza okuthembekile kwesikhathi eside.

Ukukhetha iphampu ye-hydraulic efanele kudinga ukufanisa izimfuneko zobuchwepheshe nezidingo eziqondile zendawo yokusebenza. Amasistimu e-hydraulic ahambayo, njengalawo atholakala emishinini yokumba, izinyoni zokuthwala, nemishini yezolimo, ngokuvamile adinga amaphampu amancane, alula, futhi akwazi ukusebenza ngomfutho ophezulu nezidingo zokugeleza eziguquguqukayo. Lawa masistimu avame ukusebenzisa amaphampu e-axial piston anezilawuli ezinomfutho olinganiselwe noma ezithwala umthwalo ukuze kuthuthukiswe ukonga uphethiloli futhi kuncishiswe ukukhiqiza ukushisa. Amasistimu e-hydraulic ezimboni, afaka imishini yokujova ipulasitiki, izicindezeli, nemishini yokuphatha izinto, ngokuvamile abeka phambili ukuthembeka, ukulungiseka, nokusebenza okungaguquki emijikelezweni emide yokusebenza. Kulezi zimo, amaphampu e-fixed displacement gear noma e-vane pump avamile ezinhlelweni lapho izidingo zokugeleza zihlala zingaguquki, kuyilapho amaphampu e-variable displacement piston ethandwa lapho ukugeleza kuhluka kuwo wonke umjikelezo. Izinhlelo zokusebenza zasolwandle ze-hydraulic zibeka izinselelo ezengeziwe, okuhlanganisa ukuchayeka ekugqwaleni usawoti wolwandle, isidingo sokufakwa okuhlelekile ezindlini ezinomkhawulo wezinjini, nokuhambisana namazinga ezinhlangano ezifana ne-Lloyd's noma i-DNV. Amaphampu ezinga lasolwandle avame ukuba nezinto ezikhethekile zokugqoka, izinti zensimbi ezingagqwali, nezinto zokuvala ezingagqwali ukuze amelane nezimo ezinzima. Izimo zokusebenza ezifana nezinga lokushisa elizungezile, ububanzi bokungqimba koketshezi, amazinga okungcola, nokuqina komjikelezo wokusebenza konke kuba nomthelela ekukhetheni iphampu yokugcina. Isibonelo, iphampu esebenza endaweni ebanda idinga uketshezi olungqimba oluphansi futhi ingase idinge ukugudluzwa okukhulu ukuze inxephezele ukuncipha kokugeleza ekuqaleni. Abathengi kufanele bahlole lezi zici eziqondile zohlelo lokusebenza ngokucophelela ngaphambi kokuqinisekisa ukukhetha kwabo, futhi ukubonisana nabadali abanolwazi kunganikeza isiqondiso esibalulekile. Izinkampani ezinjengeI-Guangdong MKS Hydraulic Co., Ltd. inikeza uhla olubanzi lwamaphampu asebenza ngamanzi, ama-motor, namavalvu aklanyelwe ukuhlangabezana nezidingo ezihlukahlukene zezimboni, ezihambayo, nezolwandle.

Uma kuhlolwa amaphampu e-hydraulic, ikhwalithi nokwethembeka kubaluleke njengamanani okusebenza angempela. Izinto ezisetshenziswa ekwakheni—njengensimbi eqinile yamagiya nama-piston, insimbi enwebekayo yezindlu, kanye nethusi noma izinto eziyinhlanganisela zamapuleti okugqoka—zithinta ngqo ukuqina kwephampu nokumelana nokugqokwa. Izinto zokuvala, ezihlanganisa i-nitrile, i-polyurethane, noma i-PTFE, kufanele zihambisane noketshezi lwe-hydraulic kanye nezinga lokushisa elisetshenziswayo; ukwehluleka kokuvala kungabangela ukulahleka okukhulu koketshezi nokuma komsebenzi. Amazinga okuhlola anikeza umkhombandlela oqondile wekhwalithi: i-ISO 4409 icacisa izindlela zokulinganisa ukusebenza kahle kwevolumu nokomshini, kuyilapho i-SAE J745 ihlanganisa ukuhlolwa kwengcindezi yamaphampu e-hydraulic. Izitifiketi ezifana nophawu lwe-CE zikhombisa ukuhambisana namazinga okuphepha aseYurophu, futhi isitifiketi se-ATEX siyadingeka emaphampini asetshenziswa ezindaweni ezinamandla okuqhuma. Umkhiqizi ohlonishwayo uvame ukwenza ukuhlolwa kwengcindezi okungu-100% kanye nokuqinisekiswa kokusebenza kuyunithi ngayinye ngaphambi kokuthunyelwa, eqinisekisa ukuthi ipampu ngayinye ihlangabezana nemininingwane yayo eshicilelwe. Ukwengeza, ukutholakala kwezingxenye ezishintshwayo nokusekelwa kwezobuchwepheshe kuyinkomba ebalulekile yokwethembeka: ipampu evela kumkhiqizi onenethiwekhi eqinile yokusabalalisa kanye nesevisi yamakhasimende ephendulayo izobangela ukuma komsebenzi okuncane kakhulu lapho kudingeka ukulungiswa. Kubathengi abathenga kubathengisi bomhlaba wonke, izici ezifana nesitifiketi sokuphathwa kwekhwalithi se-ISO 9001 kanye nokuhambisana namazinga emvelo kunikeza ukuzethemba okwengeziwe ekuqineni komkhiqizo nasekuqineni kokukhiqiza. Lapho ubuyekeza okunikezwa ngumthengisi, bheka imibhalo enemininingwane yobuchwepheshe, imigomo ecacile yewaranti, kanye nobufakazi bokuhlolwa kokwethembeka kwesikhathi eside.

Ukukhetha iphampu ye-hydraulic efanele ngokusebenzisa amakhodi emodeli namashidi edatha kuyinqubo ehlelekile engahlukaniswa ibe izinyathelo ezicacile. Isinyathelo sokuqala ukunquma izinga lokugeleza elidingekayo ohlelweni lwe-hydraulic, oluncike ezidingweni zejubane le-actuator kanye nenani lemisebenzi eyenziwa kanyekanye. Izinga lokugeleza lilingana ne-displacement ephindwe ngejubane le-shaft, ngakho-ke uma ukugeleza okuqondiwe sekwaziwa, i-displacement edingekayo ingabalwa ngejubane le-prime mover elitholakalayo. Isinyathelo sesibili ukusungula umfutho omkhulu wesistimu odingekayo, kuhlanganise nanoma yikuphi ukukhuphuka komfutho okungenzeka ngesikhathi sokusebenza.
