Umshini wokunyathelisa we-hydraulic wamakholomu amane uletha uwoyela we-hydraulic ku-valve block ngaphansi kwesenzo sepompo likawoyela.Isistimu yokulawula ilawula i-valve ngayinye ukuze uwoyela we-hydraulic onengcindezi ephezulu ufinyelele amakamelo angaphezulu nangaphansi kwesilinda esidonsa amanzi, okwenza umshini wokunyathelisa owenziwe ngamanzi anyakaze.I-Hydraulic press iyithuluzi elisebenzisa uketshezi ukudlulisa umfutho.
Uwoyela weHydraulic ubaluleke kakhulu emshinini wokunyathelisa we-hydraulic wamakholomu amane futhi ungenye yezinyathelo ezibalulekile zokunciphisa ukugqokwa kwemishini.Ukukhetha uwoyela olungile we-hydraulic kuhlobene ngqo nempilo yesevisi yomshini we-hydraulic.
Uma ukhetha uwoyela womshini wokucindezela we-hydraulic wekholomu emine, kufanele uqale ukhethe i-viscosity efanele.Ukukhethwa kwe-viscosity yamafutha kufanele kucabangele izici zesakhiwo, izinga lokushisa lokusebenza nokucindezela kokusebenza kwesistimu ye-hydraulic.Ohlelweni lokudluliswa kwe-hydraulic, iphampu kawoyela ingenye yezingxenye ezizwela kakhulu ekushintsheni kwe-viscosity kawoyela we-hydraulic.Izinhlobo ezahlukene zamaphampu ngayinye ine-viscosity evunyelwe ubuncane nephezulu.Ukuze kuncishiswe ukusetshenziswa kwamandla, amafutha ane-viscosity ephansi kufanele ngokuvamile asetshenziswe ngangokunokwenzeka.Kodwa-ke, ukuze ugcobe izingxenye ezibalulekile futhi uvimbele ukuvuza, uwoyela we-hydraulic we-viscosity efanele udinga ukukhethwa.

1. I-Hydraulic Oil Model Classification
Amamodeli kawoyela we-Hydraulic ahlukaniswa ngezigaba ezintathu ezijwayelekile zikazwelonke: uhlobo lwe-HL, uhlobo lwe-HM, nohlobo lwe-HG.
(1) Uwoyela we-HL wohlobo lwe-hydraulic wenziwa kusukela kuwoyela wesisekelo ocwengekile, ophakeme kakhulu ophakeme, kanye nezithasiselo zokulwa nokugqwala ezilwa nokugqwala.Ngokusho ukunyakaza at 40 degrees Celsius, viscosity ingahlukaniswa amamaki ayisithupha: 15, 22, 32, 46, 68, futhi 100.
(2) Izinhlobo ze-HM zifaka i-alkaline ephezulu, i-alkaline low zinc, i-zinc ephezulu engathathi hlangothi kanye nezinhlobo ezingenamlotha.Ngokusho ukunyakaza at 40 degrees Celsius, viscosity ihlukaniswe amamaki amane: 22, 32, 46, futhi 68.
(3) Uhlobo lwe-HG lunezinto zokulwa nokugqwala kanye ne-anti-oxidation.Ngaphezu kwalokho, isithuthukisi se-viscosity index siyengezwa, esinezici ezinhle ze-viscosity-temperature.
2. Ukusetshenziswa Kwemodeli Yamafutha E-Hydraulic
(1) I-HL uwoyela we-hydraulic isetshenziselwa ukugcoba emabhokisini aphethe kanye nezinhlelo zokujikeleza kwengcindezi ephansi yamathuluzi omshini ahlukahlukene lapho zingekho izidingo ezikhethekile zikawoyela futhi izinga lokushisa elizungezile lingaphezu kwamadigri ayi-zero Celsius.Imikhiqizo enjalo ngokuvamile inokuvumelana nezimo ezinhle kakhulu zokuvala, futhi izinga lokushisa eliphezulu lokusebenza lingafinyelela ku-80 degrees Celsius.
(2) Uwoyela we-HM we-hydraulic usetshenziswa kakhulu ezinhlelweni zokudonsa amanzi ze-heavy duty, i-medium-pressure kanye namaphampu ane-high-pressure vane, amaphampu e-plunger namaphampu egiya.Ngaphezu kwalokho, lolu hlobo lwamafutha we-hydraulic lubuye lufanele imishini yobunjiniyela ye-medium-pressure kanye ne-high-pressure kanye nezinhlelo ze-hydraulic car.
(3) Uwoyela we-HG we-hydraulic unezindawo ezinhle zokulwa nokugqwala, anti-oxidation, anti-wear, kanye ne-anti-stick-slip-slip, ngakho-ke afaneleka kakhulu amasistimu okugcoba asebenzisa ama-hydraulic amathuluzi omshini nama-rails aqondisayo.
Amazinga okushisa okusebenza kawoyela we-hydraulic amabanga ahlukene e-viscosity ngaphansi kwezidingo ezahlukene alandelayo.
| Ibanga le-viscosity (40 ℃) centistoke | I-viscosity edingekayo ekuqaleni i-860 centistoke | I-viscosity edingekayo ekuqaleni i-110 centistoke | I-viscosity ephezulu edingekayo ngesikhathi sokusebenza ingamasentimitha angama-54 | I-viscosity ephezulu edingekayo ngesikhathi sokusebenza yi-13 centistoke |
| 32 | -12 ℃ | 6℃ | 27℃ | 62℃ |
| 46 | -6 ℃ | 12℃ | 34℃ | 71℃ |
| 68 | 0℃ | 19℃ | 42℃ | 81℃ |
Kunezinhlobo eziningi zikawoyela we-hydraulic emakethe, futhi kukhona nezinhlobo eziningi zemishini esebenza ngogesi.Nakuba imisebenzi kawoyela we-hydraulic ifana ngokuyisisekelo, kusadingeka ukuthi ukhethe uwoyela we-hydraulic ohlukile wemishini eyahlukene ye-hydraulic.Lapho kukhethwa uwoyela we-hydraulic, abasebenzi kufanele baqonde ukuthi yini okucelwa ukuba bayenze, bese bekhetha uwoyela wehydraulic ofanele womshini wokudonsa amanzi.
Ungawakhetha Kanjani Amafutha EHydraulic Alungile weHydraulic Press
Izindlela ezimbili zivame ukusetshenziswa lapho kukhethwa uwoyela we-hydraulic.Enye iwukukhetha uwoyela we-hydraulic ngokuya ngezinhlobo zikawoyela kanye nemininingwane enconywe amasampula noma imiyalelo yomkhiqizi we-hydraulic press.Okunye ukucubungulisisa ukukhethwa kukawoyela we-hydraulic ngokusekelwe ezimeni ezithile zomshini we-hydraulic, njengokucindezela kokusebenza, izinga lokushisa lokusebenza, isivinini sokunyakaza, uhlobo lwezingxenye ze-hydraulic nezinye izici.
Lapho ukhetha, imisebenzi eyinhloko okufanele yenziwe yilena: ukunquma ububanzi be-viscosity yamafutha we-hydraulic, ukukhetha izinhlobonhlobo zamafutha we-hydraulic ezifanele, nokuhlangabezana nezidingo ezikhethekile zesistimu ye-hydraulic.
Ngokuvamile kukhethwe ngokuya ngezici ezilandelayo:
(1) Ngokuvumelana nezinketho ezahlukene zemishini yokusebenza yomshini wokucindezela we-hydraulic
Imishini yokunemba kanye nemishini ejwayelekile inezidingo ezihlukile ze-viscosity.Ukuze ugweme ukuguqulwa kwezingxenye zomshini okubangelwa ukunyuka kwezinga lokushisa futhi kuthinte ukunemba kokusebenza, imishini enembayo kufanele isebenzise uwoyela we-hydraulic ane-viscosity ephansi.
(2) Khetha ngokuya ngohlobo lwephampu enamanzi
Iphampu ye-hydraulic iyisici esibalulekile somshini wokunyathelisa we-hydraulic.Emshinini wokunyathelisa we-hydraulic, isivinini sayo sokunyakaza, ingcindezi kanye nokukhuphuka kwezinga lokushisa kuphezulu, futhi isikhathi sayo sokusebenza side, ngakho-ke izidingo ze-viscosity ziqinile.Ngakho-ke ipompo ye-hydraulic kufanele icatshangelwe lapho ukhetha i-viscosity.
(3) Khetha ngokuhambisana nokucindezela kokusebenza komshini wokunyathelisa we-hydraulic
Uma ingcindezi iphezulu, uwoyela one-viscosity ephezulu kufanele usetshenziselwe ukugwema ukuvuza ngokweqile kwesistimu nokusebenza kahle okuphansi.Uma ingcindezi yokusebenza iphansi, kungcono ukusebenzisa amafutha nge-viscosity ephansi, enganciphisa ukulahlekelwa kwengcindezi.
(4) Cabangela izinga lokushisa kwendawo yokusebenza yomshini wokunyathelisa osebenzisa amanzi
I-viscosity yamafutha amaminerali ishintsha kakhulu ngenxa yethonya lokushisa.Ukuze kuqinisekiswe i-viscosity efanelekile kakhulu ekushiseni okusebenzayo, ithonya lokushisa elizungezile elizungezile kufanele licatshangelwe.
(5) Cabangela isivinini sokunyakaza sezingxenye ezisebenzayo zomshini wokunyathelisa we-hydraulic
Lapho ijubane elihambayo lezingxenye zokusebenza ohlelweni lwe-hydraulic liphezulu kakhulu, izinga lokugeleza kwamafutha nalo liphansi, ukulahlekelwa kwe-hydraulic kukhula ngokungahleliwe, futhi ukuvuza kuncishisiwe, ngakho-ke kungcono ukusebenzisa amafutha ane-viscosity ephansi.
(6) Khetha uhlobo olufanele lukawoyela we-hydraulic
Ukukhetha uwoyela we-hydraulic kubakhiqizi abajwayelekile kunganciphisaumshini wokucindezela we-hydraulicukwehluleka futhi andise impilo yomshini wokunyathelisa.
