Dulmarka asalka iyo Codsiga Muuqaallada Isteerinka ee Shantui Bulldozers Nidaamka qalabaynta ee Shantui bulldozer, valve isteerinka, oo ah qayb muhiim ah oo ka mid ah nidaamka isteerinka, ayaa door muhiim ah ka ciyaara guud ahaan waxqabadka xakamaynta isteerinka ee mashiinka. Waqtigan xaadirka ah, inkasta oo xuduudaha gaarka ah ee "shirka isteerinka (B)" aan si toos ah loogu xusin natiijooyinka raadinta, naqshadeynta guud iyo macluumaadka laxiriira ee nidaamka isteerinka ee shantui SD bulldozers taxane ah ayaa lagu dari karaa si ay u bixiyaan tixraac si ay u fahmaan codsiga isteerinka valves ka aragtiyaha hawlaha nidaamka isteerinka, sifooyinka qaabeynta model caadiga ah, iwm nidaamka isteerinka ee caadiga ah qaab-dhismeedka 2 SD5 sida qaab-dhismeedka qaab-dhismeedka SD5 sida shantui SD5. waalka isteerinka oo ah qaybta kontoroolka xudunta u ah. Waxaa si weyn loogu istcimaalay xaalado hawlgal oo kala duwan sida injineernimada dhulka, macdanta, iyo dhismaha kaabayaasha, hubinta isteerinka dabacsan iyo wadista badbaadada ee qalabka ee xaaladaha adag ee shaqada.
Isku-xidhka waalka isteerinka ee cagaf-cagafku wuxuu u baahan yahay inuu si guud u tixgeliyo waxqabadka cagaf-cagaf, jawiga shaqada, cabbirada nidaamka hawo-biyoodka, iyo baahiyaha dhabta ah. Kuwa soo socda waa cabbirada muhiimka ah iyo hababka gaarka ah:
Isku beeg cabbirada ubucda ee cagaf-cagafayaasha
Tonnage iyo la qabsiga awoodda
Taxanka cagaf-cagafku wuxuu si toos ah u go'aamiyaa heerka cadaadiska iyo baahida qulqulka ee waalka isteerinka. Tusaale ahaan:
Cagaf-cagafayaasha yaryar iyo kuwa dhexdhexaadka ah (In ka yar ama la mid ah 20 tan): Sida caadiga ah dooro waalka isteerinka leh cadaadiska kala duwan ee 10-20MPa iyo heerka socodka 40-100L/daqiiqo, sida ZT taxanaha waalka hadhidarooliga ah (heerka socodka 40-100L/MP ama ka hooseeya 5).
Large bulldozers (>20 tan): waxay u baahan yihiin in lagu wajaho tilmaamo sare, sida waalka isteerinka ee loo isticmaalo 520 hooras cagaf, leh xadiga socodka 246L/min iyo cadaadiska 2.69MPa, oo lagu dhex daray is- waalka qufulka si uu ula qabsado culeyska culus iyo dhul kakan.
Laqabsiga awoodda: Tixraac awoodda duuliyaha injiinka (sida 447kW ee Caterpillar D10T2) si aad u hubiso in waalka isteerinka uu u adkeysan karo cadaadiska ugu sarreeya ee dhammaan nidaamka haydarooliga.
Waafaqsanaanta qaab-dhismeedka moodeelka
Waxaa jira farqi weyn oo u dhexeeya naqshadeynta hababka isteerinka ee moodooyinka kala duwan. Tusaale ahaan:
Crawler Buldozer: Waa lagama maarmaan in la doorto valve isteerinka taageeraya kontoroolka kala duwanaanshaha xawaaraha, sida 16Y-76-22000 isteerinka si gaar ah loogu talagalay cagaf-cagafyada SD16, kaas oo lala xiriirin karo xajinta biriiga si loo gaaro isteerin sax ah.
Cagaf-cagafeedka taayirrada leh: Tixgeli in lagu lammaaniyo waalka-weynaynta socodka (sida nooca VSFA) oo wata qalabka isteerinka si kor loogu qaado maneuverability iyada oo loo marayo mabda'a cabbir-weyneyn.
La qabsiga deegaanka shaqada iyo xaaladaha shaqada
Dhulka iyo xaaladaha rarka
Dhulalka isku dhafan (miinada, buuraha): Muhiimada waa in la siiyaa isteerinka dabaasha ee leh shaqada magdhowga cadaadiska, sida valves-ka isku dhafan ee leh valves badbaadada isku dhafan, kuwaas oo si toos ah u yareyn kara cadaadiska marka uu raadku ku dhegan yahay (cadaadiska inta badan waa 10-30MPa) si looga hortago waxyeellada qaybaha hydraulic.
Cagaf-cagafyo culus: Waa lagama-maarmaan in la doorto agabka jirka ee waalka leh iska caabin xooggan (sida sare -kabka birta ama birta), iyo in la hubiyo caabbinta xirashada xudunta waalka. Tusaale ahaan, koofiyadaha dahaarka leh ee tungsten carbide waxay u adkeysan karaan xirashada hawlaha culus ee soo noqnoqda.
Ilaalinta deegaanka ee xad dhaafka ah
Heerkul sare/hooseeya: Dooro walxaha heerkulka u adkaysta (sida silikoon carbide ceramic valve blocks oo u adkeysan kara heerkulka ilaa 1600 digrii) ama valves jihada leh magdhowga heerkulka heerkulka si looga fogaado khalkhalka uu keeno balaadhinta kulaylka iyo foosha.
Boodhka sare/ bay'ada qudhuntay: Qaadashada birta laba-laabka ah ee aan lahayn (sida 2205) ama Hastelloy valve body, oo leh O{1}} giraan xidhidh (sida fluororubber VITON) si looga hortago soo dhex galka boodhka iyo daxalka dhexdhexaadka ah
isbarbardhigga nidaamka Haydarooliga
Socodka iyo cadaadiska oo isbarbar dhigaya
Xisaabinta socodka: Iyada oo ku saleysan xawaaraha shaqada ee dhululubada isteerinka (sida xawaaraha dhaqdhaqaaqa usha piston ee 50mm/s) iyo dhexroorka dhululubo (sida φ 125mm), xisaabi heerka socodka loo baahan yahay (Q{2}}π × r ² × v) si loo hubiyo in heerka socodka ugu badan ee isteerinka (sida 120L/min) buuxiyo
Qiimaynta cadaadiska: Cadaadiska la qiimeeyay ee valve isteerinka waa inuu ka sarreeyaa cadaadiska ugu sarreeya ee nidaamka (sida caadiga ah 1.2-1.5 jeer cadaadiska shaqada). Tusaale ahaan, marka cadaadiska shaqadu uu yahay 15MPa, waa in la doortaa waalka leh cadaadiska 20MPa.
waafaqsanaanta saliidda
Xaqiiji nooca saliidda haydhiyrooliga (sida saliidda macdanta, saliidda synthetic) iyo kala duwanaanshaha viscosity (sida ISO VG 46) ee ku habboon waalka isteerinka si aad uga fogaato gabowga ama khalkhalka xudunta u ah waalka ee ay keento iswaafaq la'aanta saliidda.
Waxqabadka iyo shuruudaha shaqada
Xakamee saxnaanta iyo xawaaraha jawaabta
Dareenka xudunta valve: Dooro waalka isteerinka leh kantaroolka saamiga ama kontoroolka elektaroonigga ah (sida BPBS hydraulic gear+VSFA flow amplification valve) si loo gaaro "hagaajinta xagal yar" iyo jawaab degdeg ah, hagaajinta hufnaanta hawlgalka.
Kalsoonida soo noqoshada: Waa lagama maarmaan in la hubiyo qallafsanaanta guga soo noqoshada iyo tayada qaybaha xirmooyinka si loo hubiyo in xudunta valve si dhakhso ah ugu soo noqoto xarunta ka dib marka la sii daayo usha isteerinka, ka fogaanshaha leexashada.
Naqshadeynta amniga iyo shaqo-joojinta
Qufulka iyo xumaanta ka-hortagga: Tusaale ahaan, barreegga isteerinka ee cagaf-cagaf 520 hooras ah waxa uu dhexgeliyaa iskii - waalka quful Marka la bilaabayo, gacanku wuxuu u baahan yahay in lagu soo celiyo meeshiisii hore si looga hortago shilalka ay sababto hawl-xumo.
Nidaamka dheeraadka ah: Xaaladaha la isku halleyn karo ee sarreeya sida miinooyinka, alwaaxyada isteerinka ee aan badnayn ee leh valves solenoid ah ayaa la dooran karaa. Marka uu waalka weyni fashilmo, waxa uu si toos ah ugu wareegayaa wareegga kaydka, isaga oo yaraynaya wakhtiga hoos u dhaca.
