195-40-00800STEERING VALVE ASSY(B)
Walalka isteerinka B sida caadiga ah wuxuu qaataa cycloidal rotary valve naqshad buuxda, oo ka kooban qaybaha muhiimka ah sida jirka waalka, xudunta waalka, gacanka valve, iyo soo celinta guga. Qaab dhismeedka asaasiga ah waxaa ka mid ah: Valve body iyo dekedda saliidda: Waxaa jira dekedo laga soo galo (P), dekedaha soo laabashada (O), iyo dekedaha saliidda shaqeeya (A, B) oo ku xiran dhululubada isteerinka. marinka saliidda gudaha ayaa koontaroolaya socodka saliidda Haydarooliga iyada oo loo marayo barokicin ee core.Valve xudunta iyo gacanta valve: Xuddunta waalka waxaa kexeeyey by calaamadaha makaanikada ama koronto si ay u guurto axially gudaha sleeve waalka, beddelo xaaladda xidhiidhka marinka saliidda. Tusaale ahaan, marka xudunta valve u dhaqaaqdo dhinaca midig, wareegga saliidda waa P → A → qolka bidix ee dhululubada awoodda, gaaritaanka isteerinka bidix; Haddii kale, midig u leexo.Balancing valve core and load hold function: Qaar ka mid ah moodooyinka (sida taxanaha Crossmfg BA) waxay qaataan nashqadda asaasiga ah ee waalka si loo yareeyo daadinta oo looga hortago hoos u dhaca culeyska, hubinta xasiloonida cagafyada hoos yimaada jiirada ama xaaladaha culus ee culus Marka isteerinka uu wareego, barakicinta xudunta waalka waxa ay keentaa in saliidda hadhidarooliga ay gasho dhululubada isteerinka, iyada oo riixaysa usha piston si ay u leexiso taayiradaha. Isla mar ahaantaana, guga soo noqoshada waxay hubisaa in xudunta waalka ay si toos ah dib ugu dhigto booska dhexdhexaadka ah, ilaalinta wadista tooska ah. 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 qaab SD5 sida shantui SD5 qaab-dhismeedka caadiga ah 6. waalka isteerinka waa qaybta kontoroolka xudunta u ah. Waxaa si weyn loogu isticmaalaa xaaladaha hawlgalka bulldozer ee kala duwan sida injineernimada dhulka, macdanta, iyo dhismaha kaabayaasha, hubinta isteerinka dabacsan iyo wadista badbaadada ee qalabka ee xaaladaha adag ee shaqada.
Xaaladaha codsiga iyo cabbirrada waxqabadka
1. Goobaha codsiga ee caadiga ah
Xakamaynta isteerinka Bulldozer: Si toos ah u wad dhululubada isteerinka si aad u gaadho isteerinka xagal wayn ee ± 30 digrii ama ka badan, oo ku haboon goobaha dhismaha cidhiidhiga ah ama dhul adag.
Xawaaraha hooseeya ee culus -qalabka shaqada sida kuwa xamuulka qaada, cagaf-cagafyada, iwm. Qalabka isteerinka ee taxanaha ah ee BHR waxa uu u adkeysan karaa barokaca ilaa 1000m ³/r iyo isteerinka wareega 1.6-2.8N · m iyada oo loo marayo naqshad dhismeed la hagaajiyay.
Isteerinka gacanta degdega ah: Qaar ka mid ah moodooyinka (sida BZZ2) waxay taageeraan hawlgalka gacanta haddii ay dhacdo in mishiinku xumaado, ilaalinta shaqada isteerinka aasaasiga ah iyada oo loo marayo isku xirka farsamada.
2. Tilmaamayaasha waxqabadka muhiimka ah
Cadaadiska iyo Socodka: BLV -ZXFZ-SY-Kooxda isteerinka KTC waxay leedahay cadaadiska shaqada ugu badnaan 21MPa iyo heerka socodka 120L/min, buuxinaya shuruudaha cadaadiska sare iyo socodka ballaaran.
Xawaaraha jawaabta: Qalabka isteerinka ee dareema culeyska BHR5, iyadoo lala kaashanayo waalka mudnaanta, wuxuu gaari karaa qaybinta socodka heerka millisecond wuxuuna wanaajin karaa dareenka isteerinka.
Kalsoonida: Codsiga koofiyadaha isku dheeli tiran ee waalka iyo xidhashada{0} alaabta adkaysiga u ah (sida silikoon nitride ceramics) waxa ay kordhisaa cimriga kulanka waalka ilaa 5000 saacadood.
Tilmaamaha farsamada iyo isbeddellada warshadaha
Casriyeynta caqliga
2025, jiilka cusub ee isteerinka valve B wuxuu isku daraa xakamaynta baska iyo dareemayaasha barokaca ee CAN (sida taxanaha Hengli HSQD), kaas oo la socon kara booska xudunta u ah waalka iyo cadaadiska nidaamka wakhtiga dhabta ah, gaadha cilad-sheegid nafta iyo la socodka fog. Tusaale ahaan, iyada oo loo marayo tignoolajiyada jawaab celinta ee xidhan-, khaladka saxnaanta isteerinka waxa lagu xakamayn karaa ± 0.5 digrii gudahood.
Naqshadaynta tamarta tamarta
Qaadashada tignoolajiyada xasaasiga ah ee culeyska (sida nooca BHR5), socodka hydraulic si toos ah ayaa loo hagaajiyaa iyadoo loo eegayo culeyska isteerinka, badbaadinta 15% -20% tamarta marka loo eego kooxaha valve dhaqameed. Qaar ka mid ah moodooyinka sidoo kale waxay taageeraan "habka sabbeynaya", taas oo u oggolaanaysa cagaf-cagafku inuu si toos ah ugu habboon yahay goobta oo uu yareeyo isticmaalka tamarta.
Hal-abuurka Qalabka
Codsiga xargaha shaambada dhoobada ah (sida alumina ceramics) waxay si weyn u wanaajisaa iska caabbinta daxalka waxayna xidhataa caabbinta, waxayna kordhisaa nolosha adeegga in ka badan saddex jeer ciidda acidic ah ama jawiga boodhka sarreeya. Isla mar ahaantaana, isticmaalka agabka xidhidhiyaha ku salaysan bio-ga ayaa u hoggaansamaya heerarka deegaanka EU, taasoo hoos u dhigaysa qiiqa kaarboonka 10%. Cagaf-cagafayaasha taxanaha ah ee PLUS ayaa lagu hagaajiyay nidaamka xakamaynta, iyada oo koontaroolka isteerinka xawaaraha doorsooma uu ku urursan yahay hal gacan oo loo habeeyay dhinaca bidix ee darawalka.
Naqshadaynta isku dhafan ee kontoroolka waxay dhigaysaa baahiyo sare oo ku saabsan saxnaanta xakamaynta waalka isteerinka, isaga oo u baahan inay si sax ah uga jawaabto si ay u qabato hawlaha oo ay u gaadho ficilo isteerin ah oo hufan oo hufan. Intaa waxaa dheer, cagaf-cagafayaasha taxanaha ah ee PLUS waxay isticmaalaan tuubooyinka haragga masaska iyo T{1} qaabeeyayaasha ee xargaha fiilada baabuurta. Tuubooyinka haragga masaska ee aan cidhiidhiga lahayn waxay leeyihiin xoog sare iyo xidhid wanaagsan, taas oo si wax ku ool ah u ilaalin karta xadhkaha fiilooyinka baabuurta, oo ay ku jiraan wareegga kontoroolka waalka isteerinka, hoos u dhigida khatarta ah in waalka isteerinka lumiso xakamaynta cilladaha wareegga, iyo hagaajinta xasilloonida nidaamka isteerinka
