Imisebenzi eqondile, evumelaniswe nezidingo zezinhlelo ezivulekile ze-hydraulic
Le valve yokugcwalisa igxile ezimweni zokusetshenziswa kwezinhlelo ze-hydraulic ezivulekile. Ifakwa phakathi kwephampu kanye nedivayisi yesibili ye-hydraulic engezansi (njenge-valve yokulawula isiteringi samandla, isilinda, njll.), futhi ithatha umthwalo wemfanelo oyinhloko wokugcwalisa ngobuningi kwe-accumulator. Umsebenzi wayo oyinhloko "ukugcwalisa ngokufunwa". Ngokwezidingo zesistimu, ingathatha uwoyela kuphampu yobuningi ukuze igcwalise i-accumulator, iqedele umsebenzi wokugcwalisa ngesivinini sokugeleza esizinzile ngaphansi kwengcindezi ebekiwe, futhi igcine isimo sokugcwalisa singaguquki ngaphakathi kobubanzi bengcindezi ebekiwe.
Ngesikhathi senqubo yokugcwalisa, yize ukugeleza kwedivayisi ye-hydraulic esiza ngezansi kuzoncishiswa, ngeke kuphazamise kakhulu ukusebenza okuvamile kwengxenye. Uma nje i-valve yokugcwalisa ingavimbeli ukugeleza kanye nokudluliselwa kwengcindezi kwephampu, idivayisi ye-hydraulic yesibili engezansi ingathola njalo ingcindezi yesistimu ephelele ukuqinisekisa ukuphuma okuzinzile kwamandla esistimu. Ngesikhathi esifanayo, ukugeleza kokugcwalisa i-accumulator kanye nemikhawulo ephezulu nephansi yengcindezi ye-accumulator kungenziwa njengoba kudingeka enkambisweni yokukhiqiza, kuhlinzekwe ngezixazululo zokugcwalisa ezenziwe ngokwezifiso zezinhlelo ze-hydraulic ngaphansi kwezimo zokusebenza ezahlukene.
Izifunda ezilodwa nezimbili, ezihlanganisa izimo eziningi zohlelo lokusebenza
Lo mkhiqizo unikeza ukucushwa okubili, isekethe eyodwa kanye nesekethe ephindwe kabili, okuhlanganisa ngokunembile izidingo zezinhlelo ze-hydraulic ezinobunzima obuhlukahlukene. Ukuqhathanisa okuqondile kungokulandelayo:
| Ubukhulu bokuqhathanisa | I-valve yokugcwalisa isekethe eyodwa | I-valve yokugcwalisa isekethe ephindwe kabili |
| Izimo ezisebenzayo | Izimo ezinezakhiwo zesistimu ezilula kanye nezidingo eziphezulu zokuzimela kwesekethe eyodwa, njengesekethe yokulawula isenzo esisodwa yemishini yokwakha emincane (isb., isekethe yokwelulwa kwengalo encane kanye nesekethe yokudonsa ye-excavator encane, njll.) | Izinhlelo eziyinkimbinkimbi ze-hydraulic ezinemisebenzi yokubambisana yesekethe eminingi, njengemishini yokumba emikhulu (edinga ukulawula izenzo ezifana nokumba nokuphakamisa ngasikhathi sinye) kanye namathuluzi omshini we-hydraulic amakhulu (izimo zokucubungula ukuxhumana kwe-axis eminingi) |
| Izici | Isakhiwo esilula, siqaphela ukulawula okunembile kokushaja kwesekethe eyodwa, siqinisekisa ukuzinza nokusebenza kahle kwamandla e-hydraulic endleleni eyodwa | Ingashaja ama-accumulator ezisekethe ezimbili ngesikhathi esisodwa noma ngokwehlukana, ihlangabezane nezidingo zokucindezela nokugeleza kwezisekethe ezahlukene ngaphansi kwezimo zokusebenza eziyinkimbinkimbi |
| ivalvu | Siza imishini ukuqedela izenzo eziqondile, ezifanele izinhlelo ezilula ukunciphisa izindleko nokwandisa ukusebenza kahle | Thuthukisa ukuhlanganiswa kanye nokusebenza kahle kwezinhlelo zesekethe eziningi, okwenza imisebenzi yokubambisana yezenzo eziningi ibe bushelelezi futhi inembile. |
Izici ezinhle kakhulu, izinzuzo zokusebenza okuqinile
Ngokuphathelene nezici zomkhiqizo, leli vali lokugcwalisa libonisa izinzuzo zokusebenza okuphelele:
1. Ukucindezeleka kanye nobude besikhathi sokuphila
| Ipharamitha | Imininingwane | Inani |
| Ububanzi bokusetha ingcindezi yokushaja okulinganiselwe okuphezulu | 70 – 200bar | Isikhawu sokucindezela kokushaja sibanzi, kunciphisa imvamisa yokuqalisa kwephampu ye-hydraulic, kunciphisa ukuguguleka kwemishini, futhi kuthuthukisa impilo yesevisi yephampu ye-hydraulic kanye nohlelo. |
2. Ukugeleza kanye nomthamo wokugeleza
| Ipharamitha | Imininingwane | Inani |
| Ukucaciswa Kokugeleza Kokushaja | 3/6/10/25Lpm, izinketho eziningi ziyatholakala | Zivumelanise nezimo nezinhlelo ezinezidingo ezahlukene zokugeleza |
| Amandla Okugeleza Kwembobo Yokudlula | 5 – 113Lpm | Qinisekisa ukuthi uwoyela we-hydraulic ujikeleza kahle |
| Ukwehla Kokucindezela Kwembobo Yokudlula (uma ukugeleza < 40Lpm) | Ibha eli-5 | Nciphisa ukulahleka kwengcindezi futhi uthuthukise ukusebenza kahle kwamandla ohlelweni |
3. Ukulungiswa kwesakhiwo kanye nokulungiswa kwendawo
| Ipharamitha | Imininingwane | Inani |
| Umklamo Wesakhiwo | Isakhiwo esincane | Kulula ukuyihlela nokuyifaka ezindaweni ezincane, ihlangabezana nezidingo zokuhlanganiswa kwezinhlelo ze-hydraulic zemishini ehlukahlukene |
| Ukusebenza Okuphakathi | Uwoyela we-hydraulic osekelwe kumaminerali | Ububanzi obuphezulu, obufanele izinhlelo eziningi ze-hydraulic |
| Ububanzi be-Viscosity | 2.8 – 380mm²/s | Ingasebenza ngokuqina ezindaweni ezine-viscosities ezahlukene zamafutha |
| Ububanzi Bokushisa Kwamafutha E-Hydraulic | -30℃ kuya ku-107℃ | Ingasebenza kahle ezindaweni eziyinkimbinkimbi njengokushisa okukhulu kanye nokushisa okuphezulu |
| Izinga Lokuhlanzeka | Ihambisana nesigaba se-18/16/13 kanye nezinga le-ISO3446 | Qinisekisa ukusebenza okuthembekile ngaphansi kwezimo zokusebenza ezinzima, unciphise ukwehluleka okubangelwa ukungcoliswa kukawoyela we-hydraulic |
| Ukucindezela Kokufaka Okuphezulu | Ibha engu-210 | Ifanele izimo zokusebenza ezicindezelayo kakhulu, iqinisekisa ukuzinza kohlelo |
4. Ukucushwa okungakhethwa
Ngaphezu kokucushwa kwesekethe eyodwa/embili, ama-valve okugcwala kanye nezinye izingxenye zingakhethwa ukuze kwandiswe imisebenzi yomkhiqizo, kuhlangatshezwane nezidingo eziqondene nabasebenzisi abahlukene, futhi kuhlinzekwe ngokuguquguquka okwengeziwe komklamo wesistimu ye-hydraulic. Ochwepheshe bemboni bathi le valve yokugcwalisa yesekethe eyodwa/embili inikeza ukwesekwa okubalulekile kokusebenza kahle kwezinhlelo ze-hydraulic ezivulekile ngomklamo wayo oqondile wokusebenza, ukuzivumelanisa nezimo ezahlukahlukene kanye nokusebenza okuhle kakhulu. Ukuqaliswa kwayo ngeke kusize nje kuphela ekuthuthukiseni ukusebenza kahle kanye nokuzinza kwemishini ehlukahlukene ye-hydraulic, kodwa futhi kuzokhuthaza ukuthuthukiswa kwemishini kanye nokusungula izinto ezintsha kwezobuchwepheshe ezimbonini ezifana nemishini yobunjiniyela, i-metallurgy, kanye nokukhiqizwa kwezimboni, kufaka umfutho omusha ekuthuthukisweni kwemboni ye-hydraulic. Ngokujula kokukhuthazwa kwemakethe kanye nokusetshenziswa kwayo, kulindeleke ukuthi ibe yisilinganiso semikhiqizo ye-valve yokugcwalisa ezinhlelweni ze-hydraulic ezivulekile, okuholela imboni esigabeni sokuthuthukiswa esisebenza kahle nesihlakaniphile.
