Iumshini wokucindezela we-hydraulic wamakholomu amaneiletha uwoyela we-hydraulic ku-valve block ngaphansi kwesenzo sepompo yamafutha.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, kwenziwa inkomba ye-viscosity, enesifiso esihle sokuvilapha - izinga lokushisa.
2. Ukusetshenziswa kwemodeli yamafutha e-hydraulic kawoyela
(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 e-hydraulic lufanele futhi nengcindezi ephakathi nendawo kanye nemishini yobunjiniyela obuphakeme kanye nezinhlelo ze-hydraulic zemoto.
(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 ingama-110 centistotes | I-viscosity ephezulu edingekayo ngesikhathi sokusebenza ingamasentimitha angama-54 | I-viscosity ephezulu edingekayo ngesikhathi sokusebenza ngamasentimitha ayi-13 |
| 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.
Ungayikhetha kanjani i-hydraulic kawoyela ye-hydraulic yokucindezela kwe-hydraulic
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 nemishini ejwayelekile inezidingo ezihlukile ze-viscosity.Ukuze ugweme ukuguquguquka kwezingxenye zomshini ezibangelwa ukukhuphuka kwezinga lokushisa futhi kuthinta ukunemba okusebenzayo, imishini yokunemba kufanele isebenzise uwoyela we-hydraulic nge-viscosity ephansi.
(2) Khetha ngokuya ngohlobo lwephampu enamanzi
Iphampu ye-hydraulic iyingxenye ebalulekile ye-hydraulic Press.Esikhathini se-hydraulic, ijubane layo lokuhamba, ingcindezi kanye nokukhuphuka kwezinga lokushisa kuphezulu, futhi isikhathi sayo sokusebenza isikhathi eside, ngakho-ke izidingo zokubona intshiseko ziqinile.Ngakho-ke ipompo ye-hydraulic kufanele icatshangelwe lapho ikhetha ukubonakala.
(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.Lapho ingcindezi yokusebenza iphansi, kungcono ukusebenzisa uwoyela nge-viscosity ephansi, enganciphisa ukulahleka 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 lwamafutha e-hydraulic
Ukukhetha uwoyela we-hydraulic kubakhiqizi abajwayelekile kunganciphisaumshini wokucindezela we-hydraulicukwehluleka futhi andise impilo yomshini wokunyathelisa.
