Themakina anayi amtundu wa hydraulic pressAmapereka mafuta a hydraulic ku chipika cha valve pansi pa ntchito ya pampu yamafuta.Dongosolo lowongolera limawongolera valavu iliyonse kuti mafuta othamanga kwambiri a hydraulic afike kumtunda ndi kumunsi kwa zipinda za hydraulic cylinder, zomwe zimapangitsa kuti makina osindikizira a hydraulic asunthe.Makina osindikizira a Hydraulic ndi chipangizo chomwe chimagwiritsa ntchito madzi kutulutsa mphamvu.
Mafuta a Hydraulic ndi ofunikira kwambiri pa makina osindikizira amitundu inayi ndipo ndi imodzi mwazinthu zofunika kwambiri zochepetsera kuvala kwa makina.Kusankha mafuta olondola a hydraulic kumagwirizana mwachindunji ndi moyo wautumiki wamakina a hydraulic.
Posankha mafuta osindikizira amtundu wa hydraulic press, choyamba muyenera kusankha mamasukidwe oyenera.Kusankhidwa kwa viscosity yamafuta kuyenera kuganizira mawonekedwe ake, kutentha kwa ntchito komanso kuthamanga kwa ma hydraulic system.Mu hydraulic transmission system, pampu yamafuta ndi imodzi mwazinthu zomwe zimakhudzidwa kwambiri ndikusintha kwamafuta a hydraulic viscosity.Mitundu yosiyanasiyana ya mapampu iliyonse imakhala ndi kukhuthala kovomerezeka kochepera komanso kokwanira.Pofuna kuchepetsa kugwiritsa ntchito mphamvu, mafuta okhala ndi viscosity otsika ayenera kugwiritsidwa ntchito momwe angathere.Komabe, kuti mafuta azigawo zazikulu ndikupewa kutayikira, mafuta a hydraulic a viscosity yoyenera ayenera kusankhidwa.

1. Gulu la Mafuta a Hydraulic Mafuta
Mitundu yamafuta a Hydraulic imagawidwa m'magulu atatu amtundu wamtundu: HL mtundu, HM mtundu, ndi HG.
(1) Mafuta a HL amtundu wa hydraulic amapangidwa kuchokera ku mafuta oyeretsedwa, ozama kwambiri apakati, kuphatikizapo antioxidant ndi anti- dzimbiri zowonjezera.Malinga ndi kayendedwe ka madigiri 40 Celsius, mamasukidwe akayendedwe akhoza kugawidwa m'magulu asanu: 15, 22, 32, 46, 68 ndi 100.
(2) Mitundu ya HM imaphatikizapo zamchere zamchere, zamchere zochepa za zinc, zinki zosalowerera ndale komanso mitundu yopanda phulusa.Malinga ndi kayendedwe ka madigiri 40 Celsius, mamasukidwe akayendedwe amagawidwa m'magulu anayi: 22, 32, 46, ndi 68.
(3) Mtundu wa HG uli ndi anti-dzimbiri komanso anti-oxidation katundu.Kuphatikiza apo, chowonjezera cha viscosity index chimawonjezeredwa, chomwe chimakhala ndi mawonekedwe abwino a viscosity-kutentha.
2. Kugwiritsa Ntchito Mafuta a Hydraulic Mafuta
(1) Mafuta a HL hydraulic amagwiritsidwa ntchito popaka mafuta m'mabokosi onyamula ndi makina otsika otsika a makina osiyanasiyana omwe palibe zofunikira zapadera zamafuta komanso kutentha kozungulira kumakhala pamwamba pa zero digiri Celsius.Zogulitsa zotere nthawi zambiri zimakhala ndi kusinthasintha kwabwino kwambiri kosindikiza, ndipo kutentha kwambiri kumatha kufika madigiri 80 Celsius.
(2) Mafuta a HM hydraulic amagwiritsidwa ntchito kwambiri pama hydraulic system of heavy-duty, medium-pressure and high-pressure vane mapampu, mapampu a plunger ndi mapampu amagetsi.Kuphatikiza apo, mtundu uwu wamafuta amtundu wa hydraulic ndiwoyeneranso pazida zapakatikati komanso zothamanga kwambiri komanso zida zama hydraulic zamagalimoto.
(3) Mafuta a HG hydraulic ali ndi anti-dzimbiri, anti-oxidation, anti-wear, ndi anti-stick-slip properties, choncho ndi oyenera kwambiri pazitsulo zopangira mafuta omwe amagwiritsa ntchito makina opangira makina opangira madzi ndi njanji zowongolera.
Kutentha kwamafuta a hydraulic amitundu yosiyanasiyana ya viscosity pakufunika kosiyanasiyana ndi motere.
| Makanema a viscosity grade (40 ℃) centistoke | Kukhuthala kofunikira poyambira ndi 860 centistoke | Kukhuthala kofunikira poyambira ndi 110 centistoke | Kukhuthala kwakukulu kofunikira pakugwira ntchito ndi 54 centistokes | Kukhuthala kwakukulu kofunikira pakugwira ntchito ndi 13 centistokes |
| 32 | -12 ℃ | 6 ℃ | 27 ℃ | 62 ℃ |
| 46 | -6 ℃ | 12 ℃ | 34 ℃ | 71 ℃ |
| 68 | 0 ℃ | 19 ℃ | 42 ℃ | 81 ℃ |
Pali mitundu yambiri yamafuta a hydraulic pamsika, komanso palinso mitundu yambiri yamakina opangira ma hydraulic.Ngakhale ntchito zamafuta a hydraulic ndizofanana, ndikofunikira kusankha mafuta osiyanasiyana a hydraulic pamakina osiyanasiyana a hydraulic.Posankha mafuta a hydraulic, ogwira ntchito ayenera kumvetsetsa zomwe amafunsidwa kuti achite, ndiyeno asankhe mafuta oyenera a hydraulic pamakina a hydraulic.
Momwe Mungasankhire Mafuta Oyenera A Hydraulic a Hydraulic Press
Njira ziwiri zimagwiritsidwa ntchito posankha mafuta a hydraulic.Chimodzi ndikusankha mafuta a hydraulic molingana ndi mitundu yamafuta ndi mafotokozedwe omwe amalimbikitsidwa ndi zitsanzo kapena malangizo a wopanga makina osindikizira a hydraulic.Chinanso ndikuganizira mozama za kusankha kwamafuta a hydraulic kutengera momwe makina a hydraulic amagwirira ntchito, monga kuthamanga kwa ntchito, kutentha kwa ntchito, kuthamanga kwa mayendedwe, mtundu wa zigawo za hydraulic ndi zina.
Posankha, ntchito zazikulu zomwe ziyenera kuchitidwa ndi: kutsimikizira kukhuthala kwa mafuta a hydraulic, kusankha mitundu yoyenera yamafuta a hydraulic, ndikukwaniritsa zosowa zapadera za hydraulic system.
Nthawi zambiri amasankhidwa motengera mbali izi:
(1) Malinga ndi zosankha zosiyanasiyana zamakina osindikizira a hydraulic
Makina olondola komanso makina onse ali ndi zofunikira zosiyanasiyana za viscosity.Pofuna kupewa kusinthika kwa magawo amakina chifukwa cha kukwera kwa kutentha komanso kukhudza magwiridwe antchito, makina olondola ayenera kugwiritsa ntchito mafuta a hydraulic okhala ndi kukhuthala kochepa.
(2) Sankhani molingana ndi mtundu wa pampu ya hydraulic
Pampu ya hydraulic ndi gawo lofunikira la makina osindikizira a hydraulic.Mu makina osindikizira a hydraulic, kuthamanga kwake, kuthamanga ndi kukwera kwa kutentha kumakhala kwakukulu, ndipo nthawi yake yogwira ntchito ndi yaitali, choncho zofunikira za viscosity zimakhala zovuta.Chifukwa chake pampu ya hydraulic iyenera kuganiziridwa posankha mamasukidwe akayendedwe.
(3) Sankhani molingana ndi kuthamanga kwa makina osindikizira a hydraulic
Kupsyinjika kwakukulu, mafuta omwe ali ndi viscosity yapamwamba ayenera kugwiritsidwa ntchito kuti apewe kutayikira kwambiri komanso kuchepa kwachangu.Pamene kupanikizika kwa ntchito kuli kochepa, ndi bwino kugwiritsa ntchito mafuta omwe ali ndi ma viscosity otsika, omwe angachepetse kuthamanga kwa magazi.
(4) Ganizirani za kutentha kwa chilengedwe cha hydraulic press
Kukhuthala kwa mafuta amchere kumasintha kwambiri chifukwa cha kutentha.Pofuna kuonetsetsa kuti ma viscosity abwino kwambiri pa kutentha kwa ntchito, chikoka cha kutentha kozungulira kozungulira chiyenera kuganiziridwanso.
(5) Ganizirani za kuthamanga kwa magawo ogwira ntchito a hydraulic press
Pamene kuthamanga kwa magawo ogwira ntchito mu hydraulic system ndipamwamba kwambiri, kuthamanga kwa mafuta kumakhala kochepa, kutaya kwa hydraulic kumawonjezeka mwachisawawa, ndipo kutayikira kumachepa, choncho ndi bwino kugwiritsa ntchito mafuta omwe ali ndi viscosity yochepa.
(6) Sankhani mtundu woyenera wamafuta a hydraulic
Kusankha mafuta a hydraulic kuchokera kwa opanga nthawi zonse kumatha kuchepetsamakina osindikizira a hydrauliczolephera ndikukulitsa moyo wa makina osindikizira.
