Makhalidwe a VMGZ hydraulic mafuta

Makhalidwe aukadaulo a VMGZ

Ubwino waukulu wamafuta a hydraulic ndikudalira pang'ono kwa mamasukidwe awo pamagawo akukakamiza komanso kuthekera kogwira ntchito mokhazikika pamatenthedwe osiyanasiyana ozungulira. Kwa zigawo za Kumpoto kwa dziko lathu, mafuta a hydraulic a VMGZ amaonedwa kuti ndi nthawi yopuma, kwa ena onse akulimbikitsidwa kuti agwiritsidwe ntchito m'nyengo yozizira. Malinga ndi GOST 17479.3-85, ali ndi dzina MG-15-V (hydraulic mafuta ndi mamasukidwe akayendedwe kukhuthala kwa kutentha yachibadwa osapitirira 15 mm.²/ndi).

Analogue yapafupi kwambiri yakunja ndi mafuta a hydraulic MGE-46V (kapena HLP-15), omwe amapangidwa ndi chizindikiro cha Mobil. Komabe, palinso mitundu ina yofananira ndi cholinga kuchokera kumakampani ena. Onsewa akuyenera kutsatira mayendedwe apadziko lonse lapansi a DIN 51524-85 muyezo.

Zizindikiro zazikulu za VMGZ hydraulic mafuta:

1. Kinematic viscosity pa 50 ^°C, osati zochepa: 10.
2. Kinematic mamasukidwe akayendedwe pa -40 ^°C, osapitirira: 1500.
3. pophulikira, ^°C, osati zochepa: 135.
4. Kuchuluka kwa kutentha, ^°C, osati pansi: - 80.
5. Kachulukidwe mwadzina kutentha firiji, kg/m³: 860±5.
6. Nambala ya asidi malinga ndi KOH, osapitirira: 0,05.
7. Phulusa lovomerezeka, %: 0,15.

Magawo oyika mafuta otsika amaperekedwa chifukwa cha chithandizo cha hydrocatalytic cha maziko amafuta, pomwe zowonjezera zapadera zimawonjezeredwa.

Features wa zikuchokera ndi katundu

Zowonjezera zomwe zimapezeka mumafuta oyambira zimagawidwa m'mitundu itatu:

• Antioxidant.
• Kuchepetsa kuwonongeka kwa zida zogwirira ntchito.
• Anticoagulants.

Wogula angagwiritse ntchito gulu lomaliza la zowonjezera pawokha mwa kusintha malire a kutentha kwapakati. Choncho, n`zotheka kupeza hayidiroliki mafuta VMGZ-45, VMGZ-55 kapena VMGZ-60, angathe kuchita ntchito zawo pa kutentha osiyana zoipa (kuchuluka kwa normalized wa zowonjezera anatsimikiza ndi Mlengi mu malangizo luso). Poyeretsa mafuta, kusakhalapo kwa zinthu zovulaza m'madzi onyansa kumatsimikizika.

Pofuna kuonetsetsa kukhazikika kwa zinthu zazikulu kupanga, VMGZ hayidiroliki mafuta:

• ilibe silicon ndi zinc mankhwala omwe amachepetsa ntchito zotsutsana ndi kuvala;
• chisanadze kutsukidwa zonyansa ndi ogwira organic solvents;
• pakugwira ntchito, ngakhale pa kutentha kwapamwamba kwambiri, sikupanga phulusa lamadzi lomwe limayikidwa pamalo okhudzana;
• ilibe zida zankhondo zomwe zimachepetsa kulimba kwa zisindikizo;
• Imakhala ndi thovu lochepa, lomwe limapangitsa kuti pakhale zosavuta pakukonza zida nthawi zonse komanso kumachepetsa mwayi wa thovu la mpweya.

Phukusi lowonjezera limasankhidwa m'njira yowonetsetsa (pa chinyezi chambiri chozungulira) kulekanitsa bwino kwa madzi ndi mafuta mothandizidwa ndi zosefera zoyenera.

Kugwiritsa ntchito ndi kukhazikitsa

VMGZ mtundu hayidiroliki mafuta ndi chilengedwe ndipo ntchito:

1. Pogwiritsa ntchito ma hydraulic units a zida zomangira msewu, pogwiritsa ntchito kuthamanga kwambiri kwamadzimadzi ogwira ntchito.
2. Kuti mafuta azigudubuza ndi plain bearings ndi spur magiya.
3. Monga sing'anga yogwiritsira ntchito makina osindikizira a hydraulic kuchokera ku 2500 kN.
4. Kukonza makina amphamvu opangira zitsulo pamayendedwe apakatikati akuyenda kwa magawo ogwira ntchito.
5. Monga sing'anga yayikulu yogwirira ntchito pamakina onse aukadaulo, malo ogwirira ntchito omwe amatsatira zofunikira za DIN 51524.

Mtengo wa VMGZ hydraulic mafuta umatsimikiziridwa ndi wopanga, ndipo zimatengera kuyika kwa katundu ndi kuchuluka kwa zinthu zomwe zimagulidwa nthawi imodzi:

• Mgolo ndi mphamvu ya malita 200 - kuchokera 12500 rubles.
• Chitini chokhala ndi malita 20 - kuchokera ku ma ruble 2500.
• Chitini chokhala ndi malita 5 - kuchokera ku ma ruble 320.
• Pamene bottling pa mfundo zapaderazi muli awo - kuchokera 65 mpaka 90 rubles / l.
