Litšobotsi tsa oli ea hydraulic VMGZ
Litšobotsi tsa tekheniki tsa VMGZ
Boleng bo ka sehloohong ba ts'ebetso ea oli ea hydraulic ke ho itšetleha ka bonyane ba viscosity ea bona ho li-parameter tsa khatello ea ts'ebetso le monyetla oa ts'ebetso e tsitsitseng maemong a fapaneng a mocheso. Bakeng sa libaka tse ka leboea ho naha ea rona, oli ea hydraulic VMGZ e nkoa e le nako e seng ea nako, bakeng sa phomolo e khothalletsoa hore e sebelisoe nakong ea serame. Ho ea ka GOST 17479.3-85, e na le lebitso la MG-15-V (oli ea hydraulic e nang le viscosity ka mocheso o tloaelehileng o sa feteng 15 mm.2/c).
Analogue e haufi ka ho fetisisa ea kantle ho naha ke oli ea hydraulic MGE-46V (kapa HLP-15), e hlahisoang ke lets'oao la khoebo la Mobil. Leha ho le joalo, ho na le lihlahisoa tse ling tse ngata tse tšoanang ka morero ho tsoa ho lik'hamphani tse ling. Kaofela ha bona ba tlameha ho latela litloaelo tsa machaba tsa DIN 51524-85 standard.
Matšoao a mantlha a oli ea hydraulic VMGZ:
- Kinematic viscosity ho 50 °C, eseng ka tlase ho: 10.
- Kinematic viscosity ho -40 °C, eseng ho feta: 1500.
- flash point, °C, eseng ka tlase ho: 135.
- Mocheso o teteaneng, °C, eseng ka tlase: - 80.
- Boima ba lebitso ka mocheso oa kamore, kg/m³: 860±5.
- Nomoro ea asiti ho latela KOH, eseng ho feta: 0,05.
- Likahare tsa molora tse lumelletsoeng, %: 0,15.
Mekhahlelo ea ho beha oli e tlase e fanoa ka lebaka la kalafo ea hydrocatalytic ea setsi sa oli, moo ho kenyelletsoang li-additives tse khethehileng.
Likarolo tsa sebopeho le thepa
Li-additives tse fumanehang ka har'a oli ea motheo li arotsoe ka mefuta e meraro:
- Antioxidant.
- Ho fokotsa ho senyeha ha likarolo tse sebetsang tsa lisebelisoa.
- Li-anticoagulants.
Moreki a ka sebelisa sehlopha sa ho qetela sa li-additives ka boithaopo ka ho fetola boleng ba moeli oa mocheso o teteaneng. Ka lebaka leo, hoa khoneha ho fumana oli ea hydraulic VMGZ-45, VMGZ-55 kapa VMGZ-60, e khonang ho etsa mesebetsi ea bona ka mocheso o fapaneng o fosahetseng (tekanyo e tloaelehileng ea kenyelletso e khethoa ke moetsi ka litaelo tsa tekheniki). Ha u hloekisa oli, ho ba sieo ha likarolo tse kotsi metsing a litšila ho tiisitsoe.
E le ho netefatsa botsitso ba litšobotsi tsa mantlha tsa tlhahiso, oli ea hydraulic VMGZ:
- ha e na silicon le metsoako ea zinki e fokotsang ts'ebetso ea anti-wear;
- ho hloekisoa pele ho litšila ka li-solvents tse sebetsang hantle;
- nakong ea ts'ebetso, esita le ka mocheso o phahameng oa ts'ebetso, ha e thehe metsoako ea molora e behiloeng holim'a libaka tsa ho kopana;
- ha e na likarolo tse mabifi tsa lik'hemik'hale tse fokotsang ho tšoarella ha liqibi;
- E na le foaming e tlase, e eketsang boiketlo nakong ea tlhokomelo ea kamehla ea lisebelisoa le ho fokotsa menyetla ea li-bubble tsa moea.
Sephutheloana sa tlatsetso se khethiloe ka mokhoa oa ho netefatsa (mongobong o phahameng oa tikoloho) karohano e ntle ea metsi le oli ka li-filters tse loketseng.
Kopo le ts'ebetsong
Oli ea "hydraulic brand" ea VMGZ e fumaneha hohle 'me e sebelisoa:
- Nakong ea ts'ebetso ea li-hydraulic units tsa thepa ea kaho ea litsela, ho sebelisa lebelo le phahameng la ho tsamaea ha mokelikeli o sebetsang.
- Bakeng sa lubrication ea rolling le plain bearings le spur gears.
- E le mokhoa oa ho sebetsa bakeng sa likhatiso tsa hydraulic ho tloha 2500 kN.
- Bakeng sa tlhokomelo ea mechine e matla ea tšepe ka lebelo le bohareng la ho tsamaea ha lihlopha tse sebetsang.
- E le mokhoa o ka sehloohong oa ho sebetsa litsamaisong tsohle tsa tekheniki, maemo a ho sebetsa a lumellanang le litlhoko tsa DIN 51524.
Theko ea oli ea hydraulic VMGZ e khethoa ke moetsi, 'me e itšetlehile ka ho paka thepa le boholo ba theko ea nako e le' ngoe ea lihlahisoa:
- Moqomo o nang le matla a ho fihla ho lilithara tse 200 - ho tloha ho li-ruble tse 12500.
- Sekoti se nang le matla a lilithara tse 20 - ho tloha ho li-ruble tse 2500.
- Sekoti se nang le matla a lilithara tse 5 - ho tloha ho li-ruble tse 320.
- Ha u kenya libotlolong libakeng tse ikhethileng ka har'a lijana tsa bona - ho tloha ho li-ruble tse 65 ho isa ho tse 90 / l.
