Ukukhetha iphampu ye-hydraulic efanele yokushintsha emshinini wakho kungaba umsebenzi onzima, ikakhulukazi uma ubhekene nenqwaba yezinhlamvu nezinombolo ezigxishwe epuletini legama. Lezi zinhlamvu eziyimfihlo zomthetho wekhodi empeleni ziyindlela emfushane yobuchwepheshe eqondile, eklanywe ngabakhiqizi ukudlulisa imininingwane ebalulekile efana nokugudluzwa, izinga lokucindezela, nohlobo lokulawula. Ngaphandle kokuqonda okucacile kokuthi uhlamvu ngalunye lumele ini, ungazithola ukhetha iphampu ezosebenza kancane, isebenze ngendlela engasebenzi kahle, noma yehluleke ngaphambi kwesikhathi ohlelweni lwakho lwe-hydraulic. Lo mhlahlandlela uklanyelwe ukwenza le khodi yezinhlamvu nezibalo icace, ikunike amandla okwenza izinqumo zokuthenga ezinolwazi ngokuqiniseka. Sizohlukanisa ukwakheka kwalezi zinombolo zemodeli, sichaze imingcele ebaluleke kakhulu yobuchwepheshe, futhi sichaze ukuthi ungazifanisa kanjani nezidingo zakho ezithile zokusebenza. Ekupheleni kwalesi sihloko, uzobe usunolwazi lokufunda noma iyiphi ikhodi yemodeli yephampu ye-hydraulic njengochwepheshe onolwazi, noma ngabe uthola kumthengisi womhlaba wonke noma uthintana nomkhiqizi okhethekile njenge-Guangdong MKS Hydraulic Co., Ltd.

Inombolo yemodeli yephampu yamanzi ngamunye iyipulani emfushane echaza izici eziyinhloko zokusebenza kanye nokuhlelwa komshini wephampu. Uma udinga ukushintsha iyunithi ehlulekile, ukuhumusha le khodi yindlela esheshayo nethembekile yokuhlonza i-OEM eqondile noma isixazululo esihambisanayo semakethe. Iphampu engafani ingaholela ekungasebenzi kahle okukhulu kwesistimu, okuhlanganisa amazinga okugeleza angalungile abangela ukuchezuka kwejubane le-actuator, noma izilinganiso zomfutho ezinganele ezibangela ukuvalwa okuphelele kwesistimu ngaphansi komthwalo. Ngaphezu kwalokho, ikhodi yemodeli ivamise ukukhombisa uhlobo lomshini wokulawula—njengokunxeshezelwa komfutho, ukuzwa umthwalo, noma i-electro-proportional—enquma ukuthi iphampu isebenza kanjani nengxenye yomjikelezo wamanzi. Ukuqonda lezi zinto ezincane kuvikela utshalomali lwakho futhi kuqinisekisa isikhathi esiphezulu sokusebenza kwemishini yakho yezimboni noma imishini ehambayo. Uma ubuka uhla olubanzi lwezingxenye ezitholakalayo, njengalezo ezibalwe ku-Imikhiqizo ikhasi, ukubhekisela kukhodi yemodeli efanele yisinyathelo sokuqala sokuthola ukufana okuphumelelayo.

Izinombolo zemodeli zamaphampu amaningi we-hydraulic zilandela ifomethi enengqondo ehlanganisa izinhlamvu nezinombolo zibe yizigaba ezihlukene ezimelela izinhlobo zamaphampu, ukususwa kwamanzi, izinga lokucindezela, kanye nokukhetha kokulawula. Isibonelo, ikhodi evamile ingase iqale ngo-“A10VSO” — lapho u-“A10” ekhombisa usayizi wochungechunge, u-“V” ekhombisa iphampu ye-axial piston enokushintsha okuguquguqukayo, u-“S” ekhomba idizayini ye-swashplate, kanti u-“O” ekhombisa ukuhlelwa kwesekethe evulekile. Ngemva kwesiqalo, uvamise ukuhlangabezana nenani lokususwa kwamanzi, njengo-“45” okusho u-45 cc/rev, bese kuba nochungechunge lwezinombolo ezifaka ikhodi yezinga lokucindezela, indlela yokujikeleza, kanye nohlobo lwe-shaft. Abakhiqizi abahlukene ngokwemvelo basebenzisa izinguquko zalesi simiso; imodeli yephampu ye-Rexroth izobukeka ihlukile kumodeli ye-Kawasaki noma ye-Eaton, kodwa izimiso eziyisisekelo zihlala zifana kakhulu. Ukwazi lesi sakhiwo kukuvumela ukuthi uhlonze ngokushesha ukususwa kwamanzi, izinga lokucindezela eliphezulu lokusebenza, kanye nohlobo lokulawula ngaphandle kokudinga ukukhipha iphepha le-spec. Kulabo abasebenza nemikhiqizo ethile,Iphampu ye-Rexroth Hydraulic isigaba kuwebhusayithi ye-MKS sinikeza isibonelo esicacile sokuthi lezi zikhodi zihunyushwa kanjani zibe yimikhiqizo yangempela.

Ake sihlukanise ikhodi yemodeli ecatshangwayo kodwa engokoqobo: "PV140R1K1T1N00C". "PV" imele ipompo yepiston (enokushintshwa), "140" imele ukugudluka okungu-140 cc/rev, kanti "R1" ikhombisa indlela yokujikeleza (kwesokudla). Izinhlamvu nezinombolo ezilandelayo zikhombisa uhlobo lokulawula ("K1" kungenzeka kube isinxephezeli esithile somfutho), uhlobo lomgodi ("T1" womgodi onama-spline), kanye nokuhlelwa kokuxhuma ("N00C" wokuma okujwayelekile kwe-SAE flange). Le ndlela ehlelekile ayiyona nje into eyenziwe ngokungahleliwe; yakhelwe ukuqeda ukungaqondakali ngesikhathi sokukhiqiza, ukuphathwa kwempahla, nokushintshwa endaweni. Ngokuzijwayeza lezi zingxenye ezivamile, ungakwazi ukuhumusha izinombolo zemodeli ezivela kubakhiqizi abaningi futhi ungazulazula ngokuzethemba kumakhathalogi emikhiqizo.
