Bapisa likarolo tsa mantlha tsa li-bulldozers
Tonnage le matla a ho ikamahanya le maemo
Tonnage ea bulldozer e khetholla ka ho toba tekanyo ea khatello le tlhokahalo ea phallo ea valve e tsamaisang. Ka mohlala:
Li-bulldozers tse nyenyane le tse mahareng ({0}}ka tlase kapa li lekana le lithane tse 20): Hangata khetha valve e tsamaisang e nang le khatello ea 10-20MPa le tekanyo ea phallo ea 40-100L/min, joalo ka ZT series hydraulic directional valve (phallo ea 40-100L/min kapa khatello e lekanang le Les2MP).
Large bulldozers (>20 tons): e hloka ho tsamaisana le lintlha tse phahameng, joalo ka setereke sa brake se sebelisoang ho bulldozer ea 520 horsepower, e nang le sekhahla sa phallo ea 246L/min le khatello ea 2.69MPa, e kopantsoeng le{4}}valve e notlelang ho sebetsana ka katleho le meroalo e boima le sebaka se rarahaneng.
Ho tsamaisana le matla: Sheba matla a enjene a flywheel (a kang 447kW bakeng sa Caterpillar D10T2) ho netefatsa hore valve e tsamaisang e ka mamella khatello e phahameng ea tsamaiso eohle ea hydraulic.
Ho lumellana ha sebopeho sa mohlala
Ho na le phapang e kholo moralong oa litsamaiso tsa ho tsamaisa har'a mefuta e fapaneng. Ka mohlala:
Crawler bulldozer: Hoa hlokahala ho khetha valve e tsamaisang e ts'ehetsang taolo ea phapang ea lebelo la pina, joalo ka 16Y-76-22000 e etselitsoeng li-bulldozer tsa SD16, e ka hokahanngoang le brake clutch ho fihlela setataiso se nepahetseng.
Bulldozer e nang le mabili: Nahana ka ho hokahanya valve ea amplification ea phallo (joalo ka mofuta oa VSFA) le lisebelisoa tsa ho tsamaisa ho ntlafatsa ho tsamaisana ka molao-motheo oa ho holisa ka mokhoa o lekanang.

Ho ikamahanya le maemo a mosebetsi le maemo a mosebetsi
Boemo ba naha le maemo a boima
Libaka tse rarahaneng (merafo, lithaba): Ntho ea pele e lokela ho fanoa ho li-valve tse tsamaisang tse nang le ts'ebetso ea matšeliso ea khatello, joalo ka li-valve tse kopantsoeng tse nang le li-valve tse kopantsoeng tsa tšireletso, tse ka imollang khatello ha pina e tsitsitse (mohatla oa khatello hangata ke 10-30MPa) ho thibela tšenyo ea likarolo tsa hydraulic.
Heavy load bulldozer: Hoa hlokahala ho khetha lisebelisoa tsa 'mele tsa valve tse nang le ts'usumetso e matla (joalo ka tšepe e matla e phahameng- kapa tšepe), 'me u netefatse hore karolo ea mantlha ea valve ha e sebetse. Ka mohlala, li-valve cores tse koahetsoeng ka tungsten carbide li ka mamella ho roala ha mesebetsi e boima khafetsa.
Tšireletso e feteletseng ea tikoloho
Tikoloho ea mocheso o phahameng / o tlase: Khetha lisebelisoa tse hanyetsanang le mocheso (joalo ka li-valve tsa silicon carbide ceramic valve tse khonang ho mamella mocheso ho fihlela ho likhato tse 1600 ) kapa li-valve tsa tataiso tse nang le matšeliso a taolo ea mocheso ho qoba ho jamming ha li-valve ho bakoang ke ho atoloha ha mocheso le ho honyela.
Tikoloho e phahameng ea lerole/e senyang: Ho amohela duplex stainless steel (jwalo ka 2205) kapa mmele wa valve ya Hastelloy, e nang le O-e tiisitsweng ka ring (jwalo ka fluororubber VITON) ho thibela ho kena ha lerole le ho hola ha mahareng.

Ho tsamaisana le paramethara ea tsamaiso ea Hydraulic
Phallo le khatello e tsamaisanang
Palo ea phallo: Ho ipapisitsoe le lebelo la ho sebetsa la moqomo oa ho tsamaisa (joalo ka lebelo la motsamao oa piston oa 50mm / s) le bophara ba cylinder (joalo ka φ 125mm), bala lebelo la phallo e hlokahalang (Q=π× r ² × v) ho netefatsa hore sekhahla sa phallo e phahameng ea seterata se kopana le 0L/min 1.
Tekanyo ea khatello: Khatello e lekantsoeng ea valve ea ho tsamaisa e lokela ho ba e phahameng ho feta khatello ea tlhōrō ea tsamaiso (hangata 1.2-1.5 linako tse ling tsa khatello ea ho sebetsa). Ka mohlala, ha khatello ea ho sebetsa e le 15MPa, valve e nang le khatello e lekantsoeng ea 20MPa e lokela ho khethoa.
Ho lumellana ha oli
Netefatsa mofuta oa oli ea haeteroliki (joalo ka oli ea diminerale, oli ea maiketsetso) le mefuta ea viscosity (joalo ka ISO VG 46) e loketseng setereke sa ho tsamaisa ho qoba botsofali ba tiiso kapa tšibollo ea mantlha e bakoang ke ho se lumellane ha oli.

Litlhoko tsa ts'ebetso le ts'ebetso
Laola ho nepahala le lebelo la karabo
Sensitivity of valve core: Khetha valve e tsamaisang e nang le taolo e lekanang kapa ts'ebetso ea taolo ea elektroniki (joalo ka BPBS hydraulic steering gear + VSFA flow amplification valve) ho fihlela "phetoho e ntle ea angle angle" le karabelo e potlakileng, ho ntlafatsa ts'ebetso ea ts'ebetso.
Ho tšepahala ho khutla: Hoa hlokahala ho hlahloba ho tiea ha selemo sa ho khutla le boleng ba likarolo tsa ho tiisa ho tiisa hore motsoako oa valve o khutlela ka potlako bohareng ka mor'a ho lokolla molamu oa ho tsamaisa, ho qoba ho kheloha.
Tšireletso le boqapi bo fokolang
Ho notlela le ho thibela misoperation: Ka mohlala, valvefo ea brake ea 520 horsepower bulldozer e kopanya-valve e notlelang. Ha o qala, mofeng o hloka ho khutlisetsoa sebakeng sa oona sa pele ho thibela likotsi tse bakoang ke ho se sebetse hantle.
Sistimi ea Redundant: Maemong a ts'epahalo e phahameng joalo ka merafo, li-valve tse tsamaisang tse sa sebetseng tse nang le li-valve tsa solenoid tsa backup li ka khethoa. Ha valve e kholo e hloleha, e fetohela ho "backup circuit", e fokotsa nako ea ho theoha.
