Ikhono lokuhumusha inombolo yemodeli yepompo ye-hydraulic liyikhono elibalulekile kunoma ubani obandakanyeka ekwakhiweni, ekuthengeni, noma ekulungiseni izinhlelo zamandla oketshezi. Abakhiqizi bafaka ulwazi olubalulekile olufana nokugudluzwa, isilinganiso somfutho, uhlobo lwe-shaft, i-flange yokufaka, ukuhlelwa kwe-port, kanye nomshini wokulawula emgqeni obonakala uyimfihlo wezinhlamvu nezinombolo. Ngaphandle kwekhono lokuhumusha lezi zinhlamvu zamakhodi epompo ye-hydraulic, onjiniyela bangangena engcupheni yokukhetha ingxenye engafanele, okungaholela ekungasebenzi kahle kwesistimu, ukwehluleka ngaphambi kwesikhathi, kanye nokuma okubizayo. Ukuqonda okujulile kwalezi zicaciso kuvumela abathengi ukuqhathanisa imikhiqizo phakathi kwemikhiqizo ehlukene futhi kuqinisekise ukuthi ipompo ekhethiwe ihlangabezana nezidingo eziqondile zokusetshenziswa. Kochwepheshe abathenga kubakhiqizi abanjengoUhlobo, ukwazi lezi zikhodi yisinyathelo sokuqala sokwenza izinqumo zokuthenga ezinolwazi ezilinganisa ukusebenza nokuthembeka kwesikhathi eside. Ngaphezu kwalokho, ukujwayelana namakhodi emodeli kunika amathimba okulungisa ukuthi akhombe ngokushesha amayunithi okushintsha futhi aqinisekise ukuthi izingxenye eziyisipele zihambisana nemininingwane yemishini yokuqala, kunciphisa amathuba amaphutha okufaka ngesikhathi sokusebenza ensimini.

Ngaphambi kokukhetha iphampu, umklami wesistimu kufanele aqale anqume isidingo esiphelele sokugeleza kwawo wonke ama-actuator kumjikelezo, okuhlanganisa amasilinda nama-hydraulic motor. Kusilinda, izinga lokugeleza elidingekayo ngesikhathi lokunwetshwa libalwa ngokuphindaphinda indawo yepiston ngejubane lokunwetshwa elifiswayo, kuyilapho ukuhlehla kugeleza kubala indawo eyindilinga ezungeze induku. Uma kuhilelekile i-hydraulic motor, ukugeleza okudingekayo kutholakala ekususweni kwemoto ngokujikeleza okukodwa okuphindaphindwa ngejubane lokujikeleza okuhlosiwe, ngokuvamile kuvezwa ngamagaloni ngomzuzu noma amalitha ngomzuzu. Lezi zibalo zokugeleza ezingahluziwe kufanele zibhele ukusebenza okuhambisanayo kwama-actuator amaningi kanye nomjikelezo womsebenzi womshini ukuze kukalwe iphampu ngendlela efanele. Iphutha elivamile ukunganaki umehluko phakathi kwejubane lokunwetshwa nokuhlehla kusilinda esisebenza kabili, okungaholela ekutheni iphampu ibe ngeyanele ngakolunye uhlangothi noma ibe nkulu kakhulu kusistimu yonke. Ngokuhlanganisa ngokunembile lezi zidingo zokugeleza, unjiniyela usungula umthamo oyisisekelo okufanele iphampu iwulethe ngomfutho omkhulu wokusebenza wesistimu, okwakha isisekelo esiqinile sayo yonke imisebenzi elandelayo yokukala nokukhetha.

Uma isidingo sokugeleza kwesistimu sonke sesaziwa, isinyathelo esilandelayo esibalulekile ukuguqula lelo nani libe ukususwa kwepompo okungokwethiyori, kucatshangelwa kokubili ukulahleka kokusebenza kahle kwevolumu kanye nokusebenza kahle kwemishini. Ukusebenza kahle kwevolumu kubala ukuvuza kwangaphakathi okudlula izikhala zangaphakathi zepompo, okukhula njengoba ingcindezi ikhuphuka futhi ukuminyana koketshezi kwehla, futhi ngokuvamile kuvezwa njengephesenti lokugeleza okungokwethiyori okulethwa ngempela. Ukusebenza kahle kwemishini kubonisa ukulahleka kokungqubuzana phakathi kwezingxenye ezijikelezayo zepompo, njengamagiya, ama-vane, noma ama-piston, futhi kuthinta ngqo i-torque yokufaka edingekayo kumshini oyinhloko. Ukuze kutholwe ukususwa okudingekayo, umklami uhlukanisa ukugeleza okudingekayo ngokusebenza kahle kwevolumu okulindelekile kwepompo bese eqinisekisa ukuthi umshini oyinhloko une-torque eyanele yokunqoba ukulahleka kwemishini ekucindezelweni okuphezulu. Isibonelo, isistimu edinga u-20 GPM ku-3000 PSI ingase idinge ipompo enokususwa okungokwethiyori okungu-22 GPM ngemva kokubala ukusebenza kahle kwevolumu okungu-90%, iqinisekisa ukuthi ukugeleza okulethwayo ngempela kuhlangabezana nesidingo ngisho noma ipompo iguga ngokuhamba kwesikhathi. Abakhiqizi abahlonishwayo njengalabo abavezwe ku-Amaphampu E-Hydraulic ikhasi linikeza imininingwane yokusebenza kahle emibhalweni yabo yobuchwepheshe, okwenza kube lula ukukala nokukhetha okuthuthukisa kokubili ukusebenza nokusetshenziswa kwamandla kulo lonke uhla lokusebenza.

Ukukhetha ubuchwepheshe bepompo okufanele yisinqumo esiyisisekelo esinomthelela ebunzimeni besistimu, izindleko, kanye nokuphila isikhathi eside, futhi umndeni ngamunye wamaphampu unikeza izinzuzo ezihlukile kanye nokuhwebelana. Amaphampu egiya angawonga kakhulu futhi ayabekezelela ukungcola, okwenza adume emishinini ehambayo kanye nezinhlelo ezinomfutho ophansi kuya ophakathi, kodwa ukwakheka kwawo okungaguquki kwe-displacement kukhawulela ukuguquguquka nokusebenza kahle emfuthweni ophakeme. Amaphampu e-Vane anikeza indawo ephakathi, enikeza ukusebenza kahle okuphezulu kunamaphampu egiya kanye nekhono lokuhlelwa njengamayunithi e-variable displacement ane-pressure-compensated, nakuba ezwa kakhulu ukuhlanzeka koketshezi nokuguga ngokuhamba kwesikhathi. Esicongweni se-spectrum yokusebenza, amaphampu e-piston—atholakala kuzo zombili izinhlobo ze-axial ne-radial—anikeza amazinga aphezulu kakhulu omfutho, ukusebenza kahle okukhethekile kwe-volumetric, kanye nezinketho eziningi zokulawula, okuhlanganisa isinxephezelo somfutho, ukuzwa umthwalo, kanye nokukhawulela amandla ehhashi. Ezinhlelweni ezinokusebenza okuphezulu kwezimboni nezihambayo lapho ukonga amandla nokulawula okunembile kubaluleke kakhulu, ipompo le-axial piston seliphenduke isinqumo esijwayelekile, futhi abakhiqizi abanjengo-MKS Hydraulic banikeza uhla olubanzi lwalawa mayunithi nge-MKS Hydraulic.Iphampu ye-piston umkhiqizo. Isinqumo ekugcineni sincike ezidingweni zomfutho wesistimu, umjikelezo womsebenzi, izindleko zokuqala ezamukelekayo, kanye nokuzimisela komsebenzisi wokugcina ukutshala imali ekuhlungweni nasekugcinweni okufanele, konke okufanele kuhlolwe ngokucophelela ngesikhathi sokuklanywa ukuze kugwenywe ukubuyela emuva okubizayo kamuva.

Izinhlobo zamanje zamasistimu e-hydraulic zincikela ezindleleni eziyinkimbinkimbi zokulawula ukuze kuthuthukiswe ukusetshenziswa kwamandla, kuncishiswe ukukhiqizwa kokushisa, futhi kuthuthukiswe ukunemba komshini, futhi lezi zindlela zokulawula zivame ukusetshenziswa kumaphampu e-variable displacement piston kanye ne-vane. Iphampu enomfutho olinganiselayo inciphisa ngokuzenzakalelayo ukugudluka kwayo lapho isistimu ifinyelela umfutho omisiwe, igcina ukugeleza okwanele ukuhlangabezana nokuvuza kwangaphakathi futhi igcine isistimu isemfuthweni wokulinda ngaphandle kokumosha amandla. Ukulawula okuzwa umthwalo kuthatha isinyathelo esengeziwe ngokulungisa umphumela wephampu ukuze uvumelane nokugeleza nokucindezela okudingwa umthwalo, kusetshenziswa isignali yempendulo evela ku-valve ye-compensator elandelela umfutho omkhulu womthwalo kusekethe. Ukulawula okunciphisa amandla (noma okunciphisa i-torque) kuklanyelwe ukuvimbela umshini oyinhloko ukuthi angami ngokunciphisa ukugudluka kwephampu lapho i-torque yokufaka yeqa umkhawulo omisiwe, okubaluleke kakhulu lapho unika amandla iphampu ngenjini ye-diesel enomthamo olinganiselwe. Izilawuli zikagesi ezilinganiselayo, ezihlanganisa izilawuli zokugudluka ezisebenza nge-solenoid, zivumela ukulawula ukugudluka noma umfutho okude nokuhlelekayo, okwenza kube lula ukuhlanganiswa nama-PLC nezinhlelo zokulawula umshini zikagesi. Lezi zindlela zokulawula eziphambili zimelela ukutshalwa kwezimali okukhulu ekwakhiweni kwesistimu kodwa zikhipha inzuzo ngokusebenzisa ukuncishiswa kokusetshenziswa kukaphethiloli, amazinga okushisa asebenza aphansi, kanye nokuphila okunwetshiwe kwezingxenye—izinzuzo ezibhalwe kahle emithonjeni yobuchwepheshe etholakalayo.Izindaba ikhasi kanye nezincwadi zomkhiqizo ezivela kubakhiqizi abahamba phambili.

Ngisho nephampu enakhiwe kahle kakhulu izokhipha umsebenzi ongaphansi uma ifakwe ngendlela engafanele, okwenza ukuthobela izindinganiso ezimisiwe zokufaka kanye nezokuxhuma kube yisici esibalulekile ekuthembekeni kwesistimu. Ukuhlelwa okuvame kakhulu kokufaka amaphampu ezimboni yi-SAE two-bolt flange (SAE-A, SAE-B, SAE-C, njll.), enikeza ukuqondana okuqinisekile futhi ivimbele ukulayishwa kwe-axial ku-shaft yephampu evela kumshini oyinhloko. Izixhumanisi zamachweba nazo zilinganiselwe ngokufanayo, ne-SAE straight-thread O-ring boss (SAE O-Ring) iwuhlobo olukhulu lwamachweba ezinhlelweni zokucindezela okuphezulu ngenxa yokuvala kwayo okumelana nokuvuza, kuyilapho imicu ye-BSPP ne-NPT isatholakala ezinhlelweni zakudala noma zesifunda. Ubukhulu bomugqa wokudonsa (suction line) bubalulekile—umugqa wokudonsa omude kakhulu noma onobubanzi obuncane kakhulu udala i-vacuum eningi, okuholela ekubambeni (cavitation), umsindo, kanye nokwehluleka okuyinhlekelele kwephampu. Ukwengeza, abaklami besistimu kumele banakekele ngokucophelela ukuqondana kwe-shaft coupling, besebenzisa ama-flexible couplings avumela ukungaqondani okuncane ngaphandle kokudlulisa imithwalo eyingozi ye-radial kuma-bearing ephampu. Abakhiqizi abafana ne-Guangdong MKS Hydraulic Co., Ltd. bahlinzeka ngemihlahlandlela enemininingwane yokufaka kanye nohlu lwama-adaptha wokufaka nezinketho zamachweba, baqinisekisa ukuthi amaphampu abo ahlangana kahle kukho kokubili imiklamo emisha kanye namaphrojekthi okulungisa; ukuze uthole usizo olwengeziwe, amakhasimende angaxhumana nabo nge-oxhumana naye ikhasi lokusekelwa okuthile kohlelo lokusebenza.

Ukuhumusha imininingwane yobuchwepheshe bepompo ye-hydraulic akusiyona nje into yokufunda; kuwumkhuba osebenzayo othinta ngqo inzuzo nokwethembeka kwanoma yiluphi uhlelo lwamandla oketshezi. Kusukela ekubaleni izidingo eziyisisekelo zokugeleza nokugudluzwa kanye nezici zokusebenza kahle kuya ekukhetheni uhlobo olufanele lwepompo nobuchwepheshe bokulawula, iphuzu ngalinye lesinqumo linikeza ithuba lokwenza kahle uhlelo ukuze lihambisane nomjikelezo walo othile womsebenzi. Nakuba intengo yokuthenga yokuqala ihlala icatshangelwa, izindleko eziphelele zobunikazi—okuhlanganisa ukusetshenziswa kwamandla, ukushintshwa kwezihlungi, isikhathi sokuphumula, nokutholakala kwezingxenye eziyisipele—kumele kube isilinganiso sokugcina sokuhlola umhlinzeki wepompo. Ukusebenzisana nomkhiqizi omisiwe onikeza ukwesekwa okuphelele kobuchwepheshe, izingxenye eziyisipele ezitholakala kalula, kanye nephothifoliyo ebanzi yemikhiqizo kwenza inqubo yokucacisa ibe lula futhi kunciphise ubungozi. Njengoba usebenzisa ulwazi oluvela kulo mhlahlandlela, cabanga ukuhlola uhla oluphelele lwezinto.Imikhiqizo kanye nemibhalo yobuchwepheshe etholakala kwa-MKS Hydraulic ukuze ubone ukuthi amaphampu abo e-piston nezinye izingxenye ze-hydraulic zakhelwe ukusebenza emhlabeni wangempela kanjani. Ekugcineni, ukukhetha iphampu okungcono kakhulu yilokho okufeza ukulingana okuphelele phakathi kwezindleko zokuqala, ukusebenza kahle, kanye nokulula kokulungisa kuwo wonke umjikelezo wempilo yomshini, futhi ubudlelwano obuqinile nomthengisi onolwazi benza lokho kulingana kube lula kakhulu ukukuthola.
