Yonke ibango leenkcukacha kweli nqaku libhekisa kwiUsapho lwemveliso ye-Eaton Vickers VQkunye nemigangatho yokufakela ye-SAE kunye ne-ISO efanelekileyo.
Iimodeli ze-VQ Series ngokujonga nje — Uthelekiso lweeNkcukacha
Uthotho lweVickers VQ lugubungela i-envelope ebanzi yokusebenza ngeesayizi ezine zokufuduka. Imodeli nganye ine-envelope ebonakalayo eyahlukileyo, umgangatho we-flange, kunye nomgangatho wokusebenza. Itheyibhile engezantsi ishwankathela iinkcukacha ezibalulekileyo zokutshintshwa kwazo zonke iimodeli ezine.

Ukutshintshana Kwemilinganiselo — Yintoni Eyenza I-Bolt-Up Ibe Yiyo Ngqo
Eyona mpazamo ixhaphakileyo ekufumaneni i-VQ replacement sourcing kukuthatha ukuba "uthotho lwe-VQ" luthetha "usapho olunye olutshintshanayo." Iimodeli ezine ze-VQ zisebenzisa ubungakanani obuthathu obahlukeneyo be-mounting flange, nto leyo ethetha ukuba kuphela iimodeli ezifanayo ezitshintshanayo okanye iimodeli ezihambelanayo zomenzi ziyaphakama ngaphandle kokuguqulwa.
Ukutshintshwa kweModeli ngaphakathi — I-Bolt-Up ethe ngqo
Ii-equivalents ze-VQ zemodeli efanayo — apho ikhowudi yokufuduka, umgangatho we-flange, uqwalaselo lwe-shaft, kunye nolwalathiso lwe-port zonke zihambelana — zibopha ngokuthe ngqo ngaphandle kokuguqulwa kwenkqubo. Ezi zezona zitshintshi zinobungozi obuphantsi kwaye kufuneka zibe yikhrayitheriya yokuqala yokukhangela. Indlela echanekileyo kukuchonga uphawu lwemodeli ye-VQ oluchanekileyo kwi-nameplate yokuqala (umz., “25VQ-12R-M” okanye “45VQ-21L-A”), uze udibanise intsimi nganye yeparameter nelinganayo.
Ukutshintshwa Kwemodeli Enqamlezileyo — Xa Kusenzeka Kwaye Kungenzeki
- I-20VQ → 25VQ: Ayilotshintsho ngqo. I-20VQ isebenzisa iflange ye-SAE A ene-bolt ezimbini; i-25VQ isebenzisa iflange ye-SAE B ene-bolt ezine. Ipateni ye-bolt yokuqhoboshela, ububanzi be-pilot, kunye nobukhulu be-shaft zonke zahlukile. Kuya kufuneka i-adapter bracket eyenziwe ngokwezifiso - ezisa ulungelelwaniso, ibhalansi, kunye nemingcipheko yokuthembeka kwinkqubo ye-hydraulic.
- 25VQ → 20VQ: Ayikhuthazwa. I-25VQ isebenza ngoxinzelelo oluphezulu (ibha ye-190 vs i-175 bar). Ukufakela i-20VQ kwinkqubo eyenzelwe i-190 bar kunokubangela ukungasebenzi kakuhle kwepompo xa ivalvu yokunceda ivuleka ngaphezu kwe-175 bar.
- 35VQ → 45VQ: Inokwenzeka ngononophelo. Zombini zisebenzisa ii-flange ze-SAE B okanye ze-BB ezine-bolt ezine-4, kodwa i-45VQ inobubanzi obukhulu be-pilot kunye ne-shaft enkulu. Abanye abavelisi banikezela nge-45VQ equivalents "ehambelana ne-flange" ezamkela ukufakwa kwe-35VQ. Qinisekisa nomthengisi ngaphambi kokuba u-odole.
- 35VQ → 25VQ: Ayitshintshi ngqo. I-45VQ isebenzisa i-SAE C okanye i-SAE BB flange; 35VQ isebenzisa i-SAE B. Qinisekisa ukuhambelana kwe-flange ngaphambi kokuba u-odole.
Uluhlu lokujonga izigqibo zeFlange kunye neShaft
Ngaphambi kokuba u-odole i-VQ equivalent, qinisekisa zonke iiparameter ezintlanu ezingezantsi. Ukungafani kuyo nayiphi na iparameter enye kuya kuthintela ukufakwa okucocekileyo:
- I-flange esemgangathweni yokuxhoma — SAE J744 2-bolt (A) ye-20VQ; SAE J744 4-bolt (B) ye-25VQ kunye ne-35VQ; SAE J744 4-bolt (C okanye BB) ye-45VQ. Qinisekisa nge-nameplate okanye nge-datasheet yokuqala.
- Uhlobo lweshaft kunye nobukhulu — Isitshixo (chaza ububanzi besitshixo × ububanzi beshaft × ubunzulu besitshixo) okanye i-splined (chaza uthotho lwe-SAE spline, inani lamazinyo, kunye ne-engile yoxinzelelo). Linganisa ngee-calipers ukuba i-nameplate ayifundeki.
- Umgangatho kunye nobukhulu bentambo yePort — i-SAE O-ring boss (eqhelekileyo kwi-20VQ/25VQ) okanye i-SAE split-flange (eqhelekileyo kwi-35VQ/45VQ). Qinisekisa uhlobo lwentambo ye-mating fittings ngaphambi kokuba u-odole.
- Ukujongwa kweClocking/port — Iimpompo zeVQ zineendawo ezininzi zokujongwa kweClocking (umz., “A” = 0°, “B” = 90°, “C” = 180°). Ukujongwa ngokuchanekileyo kumisela ukuba ipompo ifanele indawo yokufaka i-reservoir.
- Uvavanyo loxinzelelo kunye nokuhamba kwamanzi — Utshintsho kufuneka luhlangabezane okanye ludlule uxinzelelo oluphezulu lokusebenza lweyokuqala. Ukulinganisa ukufuduka ngokujikeleza ngaphakathi kwe-±10% kuyamkeleka kwiisekethe zokufuduka ezisisigxina.
Ukhetho Oluhambelana Nezicelo — Iimeko Zoshishino
Iimfuneko zenkqubo ye-hydraulic ziyahluka ngokwendlela esetyenziswa ngayo ngeendlela ezingaphaya koxinzelelo oluluhlaza kunye namanani okuhamba kwamanzi. I-VQ equivalent efanelekileyo kwi-marine application ayifani ngokuyimfuneko ne-equivalent efanelekileyo kwi-plastics injection molding press. Apha ngezantsi kukho iimeko ezine eziqhelekileyo ze-application kunye nezinto ezibekwa phambili nganye nganye.
Oomatshini bokuQhuba iinqanawa kunye neDekhi
Iinkqubo zolwandle zifuna iimpompo ezisebenza ngokuthembekileyo kwiindawo ezinomswakama ophezulu, umoya wetyuwa kunye nesatifikethi sombutho wokwahlulwahlulwa. Eyona nto iphambili sisatifikethi se-BV, DNV, ABS, LR, okanye i-CCS - kungekuphela nje kweenkcukacha zobugcisa. Kwimikhumbi yorhwebo, umbutho wokwahlulwahlulwa ubeka umgangatho ophantsi owamkelekileyo, kwaye ukutshintshwa okungahlelwanga akuyi kuphumelela kuhlolo lwe-port state. I-VQ equivalent kufuneka ikwanyamezele ukungcangcazela kunye nokuhamba ngebhayisekile okuqhelekileyo kwamagumbi eenjini zaselwandle. I-Vicks Hydraulic inikezela nge-VQ equivalent ngeesatifikethi zokuvuma uhlobo lombutho wokwahlulwahlulwa ezikhoyo kwi-CCS, DNV, ABS, BV, kunye ne-LR.Iimpompo zokutshintsha ii-VQ SeriesKwizicelo zaselwandle, iindlela zokuvala ityuwa kunye nokukhusela ukugqwala okuphuculweyo kwiindawo zangaphandle.
