Umshini wokucindezela we-hydraulic onezinsika ezine uletha uwoyela we-hydraulic ku-valve block ngaphansi kokusebenza kwephampu kawoyela. Uhlelo lokulawula lulawula i-valve ngayinye ukuze uwoyela we-hydraulic onengcindezi ephezulu ufinyelele emakamelweni aphezulu nangaphansi esilinda se-hydraulic, okwenza umshini wokucindezela we-hydraulic uhambe. Umshini wokucindezela we-Hydraulic uyithuluzi elisebenzisa uketshezi ukudlulisa ingcindezi.
Uwoyela we-hydraulic ubaluleke kakhulu ekucindezelweni kwe-hydraulic okunamakholomu amane futhi ungenye yezinyathelo ezibalulekile zokunciphisa ukuguguleka komshini. Ukukhetha uwoyela we-hydraulic ofanele kuhlobene ngqo nokuphila kwenkonzo yomshini we-hydraulic.
Uma ukhetha uwoyela womshini wokucindezela we-hydraulic onezinsika ezine, kufanele uqale ukhethe i-viscosity efanele. Ukukhethwa kwe-viscosity kawoyela kufanele kucabangele izici zesakhiwo, izinga lokushisa lokusebenza kanye nengcindezi yokusebenza yesistimu ye-hydraulic. Ohlelweni lokudlulisa i-hydraulic, iphampu kawoyela ingenye yezingxenye ezibucayi kakhulu ezinguqukweni ze-viscosity kawoyela we-hydraulic. Izinhlobo ezahlukene zamaphampu ngayinye ine-viscosity encane nephezulu evumelekile. Ukuze kuncishiswe ukusetshenziswa kwamandla, uwoyela one-viscosity ephansi kufanele ngokuvamile usetshenziswe ngangokunokwenzeka. Kodwa-ke, ukuze kugcotshwe izingxenye ezibalulekile futhi kuvinjelwe ukuvuza, uwoyela we-hydraulic one-viscosity efanele udinga ukukhethwa.

1. Ukuhlukaniswa Kwemodeli Yamafutha E-Hydraulic
Amamodeli kawoyela we-hydraulic ahlukaniswe ngezigaba ezintathu ezijwayelekile zikazwelonke: uhlobo lwe-HL, uhlobo lwe-HM, kanye nohlobo lwe-HG.
(1) Uwoyela we-hydraulic wohlobo lwe-HL wenziwe ngowoyela wesisekelo ophakathi ocwengekile, ojulile kakhulu, kanye nezithasiselo ze-antioxidant kanye ne-anti-rust. Ngokusho kokunyakaza kuma-degree Celsius angu-40, i-viscosity ingahlukaniswa ngamagremu ayisithupha: 15, 22, 32, 46, 68, kanye ne-100.
(2) Izinhlobo ze-HM zifaka phakathi i-alkaline ephezulu, i-alkaline ephansi, i-zinc ephezulu ne-neutral kanye nezinhlobo ezingenawo umlotha. Ngokusho kokunyakaza kuma-degree Celsius angu-40, i-viscosity ihlukaniswe ngamagremu amane: 22, 32, 46, kanye no-68.
(3) Uhlobo lwe-HG lunezakhiwo zokulwa nokugqwala kanye nokulwa nokugqwala. Ngaphezu kwalokho, kufakwe i-viscosity index improver, enezici ezinhle ze-viscosity-temperature.
2. Ukusetshenziswa Kwemodeli Yamafutha E-Hydraulic
(1) Uwoyela we-HL hydraulic usetshenziselwa ukugcoba emabhokisini okuthwala kanye nezinhlelo zokujikeleza ezinomfutho ophansi zamathuluzi ahlukahlukene omshini lapho kungekho khona izidingo ezikhethekile zamafutha futhi izinga lokushisa elizungezile lingaphezu kwama-degree Celsius ayi-zero. Imikhiqizo enjalo ngokuvamile inokuguquguquka okuhle kakhulu kokuvala, futhi izinga lokushisa lokusebenza eliphezulu lingafinyelela kuma-degree Celsius angama-80.
(2) Uwoyela we-hydraulic we-HM usetshenziswa kakhulu ezinhlelweni ze-hydraulic zamaphampu e-vane asebenza kanzima, aphakathi nendawo kanye naphezulu, amaphampu e-plunger kanye namaphampu egiya. Ngaphezu kwalokho, lolu hlobo lwamafutha e-hydraulic lufanelekela nemishini yobunjiniyela esezingeni eliphakathi nendawo kanye nezinhlelo ze-hydraulic zezimoto.
(3) Uwoyela we-hydraulic we-HG unezakhiwo ezinhle zokulwa nokugqwala, ukulwa nokugqwala, ukulwa nokuguguleka, ngakho-ke ufaneleka kakhulu ezinhlelweni zokugcoba ezisebenzisa ama-hydraulic amathuluzi omshini kanye nezinsimbi zokuqondisa.
Amazinga okushisa okusebenza kwamafutha e-hydraulic anezinga elihlukile le-viscosity ngaphansi kwezidingo ezahlukene angokulandelayo.
| Ama-centistokes ebanga lokuthamba (40℃) | I-viscosity edingekayo ekuqaleni yi-860 centistokes | I-viscosity edingekayo ekuqaleni yi-110 centistokes | I-viscosity ephezulu edingekayo ngesikhathi sokusebenza yi-54 centistokes | I-viscosity ephezulu edingekayo ngesikhathi sokusebenza yi-13 centistokes |
| 32 | -12℃ | 6℃ | 27℃ | 62℃ |
| 46 | -6℃ | 12℃ | 34℃ | 71℃ |
| 68 | 0℃ | 19℃ | 42℃ | 81℃ |
Kunezinhlobo eziningi zamafutha e-hydraulic emakethe, futhi kunezinhlobo eziningi zemishini ye-hydraulic. Nakuba imisebenzi yamafutha e-hydraulic ifana kakhulu, kusadingeka ukukhetha amafutha e-hydraulic ahlukene emishini ye-hydraulic ehlukene. Lapho ukhetha uwoyela we-hydraulic, abasebenzi kufanele baqonde ukuthi yini eceliwe ukuba bayenze, bese bekhetha uwoyela we-hydraulic ofanele womshini we-hydraulic.
Indlela Yokukhetha Uwoyela Ofanele We-Hydraulic Wokucindezela Kwe-Hydraulic
Izindlela ezimbili zivame ukusetshenziswa lapho kukhethwa uwoyela we-hydraulic. Enye ukukhetha uwoyela we-hydraulic ngokwezinhlobo zamafutha kanye nemininingwane enconywe amasampula noma imiyalelo yomkhiqizi we-hydraulic press. Enye ukucabanga ngokuphelele ngokukhethwa kwamafutha we-hydraulic ngokusekelwe ezimweni ezithile zomshini we-hydraulic, njengokucindezela kokusebenza, izinga lokushisa lokusebenza, isivinini sokunyakaza, uhlobo lwezingxenye ze-hydraulic nezinye izici.
Uma ukhetha, imisebenzi eyinhloko okufanele yenziwe yile: ukunquma ububanzi be-viscosity yamafutha e-hydraulic, ukukhetha uhlobo olufanele lwamafutha e-hydraulic, kanye nokuhlangabezana nezidingo ezikhethekile zesistimu ye-hydraulic.
Ngokuvamile kukhethwa ngokwezici ezilandelayo:
(1) Ngokusho kokukhetha okuhlukile kwemishini yokusebenza ngokucindezela kwe-hydraulic
Imishini eqondile kanye nemishini ejwayelekile inezidingo ezihlukile ze-viscosity. Ukuze kugwenywe ukuguquguquka kwezingxenye zomshini okubangelwa ukwenyuka kwezinga lokushisa futhi kuthinte ukunemba kokusebenza, imishini eqondile kufanele isebenzise uwoyela we-hydraulic one-viscosity ephansi.
(2) Khetha ngokuya ngohlobo lwephampu ye-hydraulic
Iphampu ye-hydraulic iyisici esibalulekile somshini wokucindezela we-hydraulic. Kumshini wokucindezela we-hydraulic, isivinini sayo sokunyakaza, ingcindezi kanye nokwenyuka kwezinga lokushisa kuphakeme, futhi isikhathi sayo sokusebenza side, ngakho-ke izidingo ze-viscosity ziqinile. Ngakho-ke iphampu ye-hydraulic kufanele icatshangelwe lapho ukhetha i-viscosity.
(3) Khetha ngokuya ngengcindezi yokusebenza komshini wokucindezela we-hydraulic
Uma ingcindezi iphezulu, uwoyela one-viscosity ephezulu kufanele usetshenziswe ukugwema ukuvuza ngokweqile kwesistimu kanye nokusebenza kahle okuphansi. Uma ingcindezi yokusebenza iphansi, kungcono ukusebenzisa uwoyela one-viscosity ephansi, okunganciphisa ukulahleka kwengcindezi.
(4) Cabanga ngokushisa kwendawo yokusebenza komshini wokucindezela we-hydraulic
Ukuqina kwamafutha amaminerali kushintsha kakhulu ngenxa yethonya lokushisa. Ukuze kuqinisekiswe ukuqina okufaneleka kakhulu ekushiseni okusebenzayo, ithonya lokushisa elizungezile kufanele licatshangelwe.
(5) Cabanga ngesivinini sokuhamba kwezingxenye zokusebenza zomshini wokucindezela we-hydraulic
Uma ijubane lokuhamba kwezingxenye ezisebenzayo ohlelweni lwe-hydraulic liphezulu kakhulu, izinga lokugeleza kukawoyela nalo liphansi, ukulahleka kwe-hydraulic kuyanda ngokungahleliwe, futhi ukuvuza kuyancipha, ngakho-ke kungcono ukusebenzisa uwoyela one-viscosity ephansi.
(6) Khetha uhlobo olufanele lwamafutha e-hydraulic
Ukukhetha uwoyela we-hydraulic kubakhiqizi abavamile kunganciphisaumshini wokucindezela we-hydraulicukwehluleka futhi kwandise impilo yomshini wokunyathelisa.
