Mafuta a MGE-46V. Miyambo ndi makhalidwe

Mapangidwe ndi mawonekedwe

Chidule cholembera chimaphatikizanso kutchulidwa kwa gawo la ntchito (mafuta a hydraulic) ndi mtengo wapakati wa viscosity ya kinematic mu kutentha kwa ntchito (46 mm.²/ndi). Matchulidwe ena sagwiritsidwa ntchito kwambiri - mafuta amtundu wa NM-46 (kuchokera ku "mafuta amafuta") ndi mafuta a MG-30U.

Mfundo yaikulu kudziwa mphamvu ya ntchito MGE-46V mafuta ndi kukhazikika kwa mamasukidwe akayendedwe ake ku makhalidwe chachikulu ntchito - mikangano mikhalidwe, liwiro kutulutsa sing'anga ntchito mapaipi ndi kutentha kunja mpweya. Panthawi imodzimodziyo, kuthamanga kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kakafika mpaka 35 MPa zikhala zosachepera 42 MPa.

Ukadaulo wopangira mafuta umaphatikizapo kuyeretsedwa kwamafuta am'mafakitale, ndikuwonjezera zowonjezera zowonjezera pamunsi pake - antioxidant, anti-corrosion, depressant and anti-foam. Zotsatira zake, mafuta a MGE-46V amakhala ndi makhalidwe awa:

• Kuthekera kopambana kukana njira zokangana zomwe zimawonjezeka ndi nthawi ya hydraulic control system.
• Kukaniza kuvala kwa okosijeni, komwe kumachitika chifukwa cha kukhalapo kwa mpweya m'mipata pakati pa malo opaka.
• Kufanana kwa kachulukidwe mu voliyumu yonse yogwirira ntchito, mosasamala kanthu za liwiro ndi kuthamanga kwa sing'anga yogwirira ntchito.

Tiyenera kudziwa kuti mafuta a hydraulic MGE-46V (komanso mafuta ochepera a viscous hydraulic MGE-10A) amapangidwa motsatira miyezo yapadziko lonse lapansi - DIN EN 51524-2 ndi ISO 3104. Zofananira zapafupi kwambiri zakunja ndi mafuta a HLP-46 ochokera ku chizindikiro cha Britain Petroleum ndi mafuta a Tellus 46 ochokera ku chizindikiro cha Shell.

Zolemba zamakono

Yaikulu ndi:

1. Kachulukidwe kutentha firiji, kg/m³: 880 ± 10.
2. Kinematic mamasukidwe akayendedwe, mm²/s pa kutentha kwa 0 °C, osapitirira: - 1000.
3. Mitundu yosiyanasiyana ya viscosity ya kinematic, mm²/ s, pa kutentha kwa 40 ° C: 41,4 ... 50,6.
4. Kinematic mamasukidwe akayendedwe, mm²/s pa kutentha kwa 100 °C, osachepera: - 6.
5. pophulikira, ^°C, osati zochepa: 190.
6. Kutentha kwakukulu, ° С, osachepera: -32.
7. Nambala ya asidi malinga ndi KOH: 0,07 ... 0,11.
8. Kukhalapo kwa zonyansa zosasungunuka,% pa moyo wautumiki wa maola 2500, osapitilira: 0,05.

Kukhalapo kwa madzi ndi zinthu zaukali za organic sikuloledwa mumafuta atsopano (zotsirizirazi zimatheka ndi kukonza kowonjezera kwamafuta ndi nthunzi zosungunulira).

Ngati mafuta amtundu wa VMGZ hydraulic alipo, amatha kugwiritsidwa ntchito m'malo mwa mtundu wamafuta omwe akufunsidwa powonjezera kutsanulira kutsitsa kwamafuta atsopano, omwe amathandizira kuchepetsa kuzizira kwamafuta. Pankhaniyi, chifukwa zikuchokera ndi intensively wothira mosalunjika (koma osati mwachindunji!) Kutentha kwa chidebe. Calcium alkyl phenolate, chowonjezera cha K-110D, kapena zinthu zina zotchulidwa ndi wopanga mafuta zimalimbikitsidwa ngati zowonjezera zokhumudwitsa.

Ntchito

Maminolo opangidwa ndi hydraulic mafuta amtundu wa MGE-46V, wolingana ndi gulu lapadziko lonse la ISO, amawonetsetsa kugwira ntchito kwa ma hydraulic system omwe akugwira ntchito pazitsenderezo zazikulu komanso zomwe zimafunikira kupanikizika kwambiri. Mafutawa ndi oyeneranso ntchito zina zomwe zimafuna kukana kwambiri kumayendedwe a okosijeni: mwachitsanzo, pamakina otumizirana mawotchi omwe akugwira ntchito pansi pa katundu wopepuka, komanso ma drive omwe ali ndi liwiro losiyanasiyana lotsetsereka pamalo onyamula.

Mafuta a Hydraulic MGE-46V amagwirizana kwathunthu ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi elastomeric, zomwe zimagwiritsidwa ntchito polumikizira mafupa: perfluorates, nitrile butyls, polyurethanes kapena polyester.

Mitundu yabwino kwambiri yama injini omwe akuyenda pamafuta:

1. Mapampu a Vane.
2. Mapampu a piston.
3. Mapampu amagetsi.
4. Magalimoto a Hydraulic.

Panthawi yogwira ntchito, zosefera zamafuta ziyenera kutsukidwa nthawi ndi nthawi, ndipo mafuta sayenera kusakanikirana ndi zofalitsa zina zofananira popanda kuyang'anira zizindikiro zomaliza za viscosity zomwe zimalimbikitsidwa ndi wopanga. Osasunga mafuta m'mitsuko yotseguka.

Mtengo wa mafuta a MGE-46V

Mtengo wa chinthucho umatsimikiziridwa ndi zinthu zitatu - kuchuluka kwa kugula, wopanga, ndi mawonekedwe a phukusi:

• mbiya 200 L - kuchokera 11000 rubles.
• Canister 20 L - kuchokera 1400 rubles.
• Canister 10 L - kuchokera 450 rubles.
