Saliida Hydraulic VMGZ
Tusmo
Waddankeena, qaybta saliidaha hydraulic waa mid aad u horumarsan. Mid ka mid ah alaabooyinka qaybtan waa saliid VMGZ. Soo gaabintan waxaa lagu qeexaa: "saliid hydraulic oo dhumucdey xilliyada oo dhan." Noocani waa mid ku baahsan dalkeena. Saliida Hydraulic ee astaantani waxay ka shaqeysaa unugyo aan la tirin karin. Caan ku ah xaalado badan sida VMG three.
Magaca sida waafaqsan GOST
Marka loo eego GOST 17479.3, astaantan waxaa loo magacaabay MG-15-V:
- "MG" - saliid hydraulic macdanta;
- "15" - heerka viscosity. Tani waxay ka dhigan tahay in marka uu gaaro 40°C viscosity kinematic uu yahay 13,50 - 16,50 mm2/s (cSt)
- "B" - kooxda waxqabadka. Tani waxay ka dhigan tahay in saliidaha macdanta lagu sameeyay antioxidant, anti-corrosion iyo daroogooyinka ka hortagga xirashada. Meesha lagu taliyay ee codsiga waa nidaamyada hawo-mareenada leh bambooyin nooc kasta ah oo cadaadis ah in ka badan 25 MPa iyo heerkulka saliidda 90 ° C.
Astaamaha, baaxadda
VMGZ waxaa loo isticmaalaa sida dareeraha hydraulic ee kala duwan ee wax soo saarka, dhismaha, kaymaha, iyo sidoo kale dhammaan meelaha suurtogalka ah ee tiknoolajiyada hydraulic ka jirto. Tani waxay sabab u tahay xaqiiqda ah in saliidda VMGZ ay tahay mid wax ku ool ah, waxaa lagu hayaa xaaladaha shaqada -35 ° C ilaa + 50 ° C, taas oo u oggolaanaysa mashiinnada inay ka shaqeeyaan inta badan dhulka dalkeena xilliga qaboobaha iyo xagaaga iyada oo aan loo baahnayn. si loo beddelo dareeraha hydraulic. Xaaladaha bartamaha Ruushka, waxaa lagu talinayaa in loo isticmaalo dalagyada jiilaalka. Sidoo kale faa'iidada weyn ee noocan oo kale ah ayaa ah in loo isticmaali karo in lagu bilaabo matoorada hydraulic heerkulka hooseeya.
VMGZ waxaa lagu heli karaa saddex nooc oo ku kala duwan dhibicda shubista iyo viscosity (hoos u dhaca dhibicda shubka, hoose ee viscosity):
- VMGZ-45 ° C
- VMGZ-55 ° C
- VMGZ-60 ° C
Soo-saareyaasha iyo teknoolojiyadda wax-soo-saarka
Soo saarayaasha ugu muhiimsan ee saliidda VGMZ
Waqtigan xaadirka ah, waxaa dalkeena ka jira saddex shirkadood oo soo saara saliidda VMGZ:
- Gazpromneft
- Rosneft
- Lukoil
Qeybta ugu muhiimsan waa saliid tayo wanaagsan leh oo lagu sameeyay sifeyn xulasho leh oo leh maaddo baaruud ah oo ugu yar. Qaybaha noocan oo kale ah waxay leeyihiin viscosity hoose oo firfircoon iyo dhibic shub ah oo taban. Dhammaan guryaha kale ee sumadda VMGZ ay leedahay waxaa lagu gaaraa waxyaabo lagu daro oo kala duwan kuwaas oo bixiya dharka ka-hortagga, xumbo-ka-hortagga, antioxidant-ka iyo guryaha daxalka.

MEESHA TOgan
- Waxay bixisaa ilaalin la isku halleyn karo oo ah qaybaha gudaha ee ka hortagga daxalka iyo xirashada farsamada;
- Kala duwanaansho ballaaran oo dareeruhu ku jiro xaaladaha shaqada, laga bilaabo - 35 ° C ilaa + 50 ° C;
- Awoodda lagu bilaabi karo nidaamka iyada oo aan horay loo sii kululayn;
- Looma baahna beddelka dareeraha hydraulic xilliyeed;
- Guryaha ka-hortagga xumbo-ku-soo-saarka waxay kaa caawinayaan inay yareeyaan khilaafka dareeraha shaqada;
Talo-yaqaanno ku saabsan xulashada iyo hawlgalka
Ha isticmaalin VMGZ la isticmaalay ama dareere tayadiisu hoosayso, iyo xataa in ka badan oo aan la garanayn meesha uu ka yimid.
Cawaaqibta shaqada ee tayada hooseeysa ee VMGZ:
- Heerka sare ee wasakhowga, qaybaha gudaha ee nidaamyada hydraulic.
- Kala shaandhaynta xidhidhiyaha iyo fashilka
- Heerka sare ee xirashada iyo daxalka qaybaha gudaha.
- Guuldarada ay sabab u tahay isbiirsaday qodobada kor ku xusan.
Fikradda khubarada: Wakhtiga dhimista ee mishiinnada qaarkood aad bay qaali u tahay, markaa isha ku hay xaaladda dareeraha hydraulic-ga oo u beddel wakhtiga ku habboon.
Markaad dooranayso, had iyo jeer ka qaado soosaarayaasha la aamini karo. Guryaha ugu muhiimsan ee VMGZ waxay ku dhow yihiin isku mid dhammaan soosaarayaasha. Wax-soo-saarayaashu waxay beddeleen isku-dhafka antioxidant-ka iyo kuwa-daxalka ka-hortagga. Si taxadar leh u darso halabuurka oo dooro saliidda kaa caawin doonta inaad sare u qaaddo nolosha nidaamyadaaga hawo-mareenka. Xaaladna ha ka bilaabin qiimaha.
Laba arrimood oo muhiim ah in la tixgeliyo marka la dooranayo:
- Qayb ka mid ah guryaha ay saliida VMGZ bixiso (oo lagu tilmaamay dukumeenti farsamo);
- Caannimada iyo awoodda summada ee isticmaalayaasha nidaamyada hawo-biyoodka;
Saliida Haydarooliga LUKOIL VMGZ
