Isku-xidhka Imtixaanka Cadaadis-sare ee 630 Bar ee Nidaamyada Haydarooliga

ISO 15171 waafaqsan yahay. Cabbiraadda cadaadis-free-leaks, muunad dareere ah, iyo hawo wareegga ilaa 630 bar. Cabbirrada dunta la isku hagaajin karo, alaabta shaabadaysan, iyo biraha jidhka

Waa maxay Isku-xidhka Tijaabada Haydarooliga?

Isku-xidhka tijaabada hydraulic (sidoo kale loo yaqaan  isku-xidhka ogaanshaha  ama  barta tijaabada ) waa qalab is haysta oo si toos ah loogu rakibay wareegga haydarooliga. Waxay ku siinaysaa deked gelitaan heersare ah oo aad ku xidhi karto cabirka cadaadiska, tuubada tijaabada, ama muunada muunada ilbidhiqsiyo gudahood - ma xidhidh, majiro khad, wax dareere ah oo lumin.

Shaabada qaabka poppet-guhu way xidhan tahay ilaa tuubada tijaabada ee isku dhafka ah ay riixdo furitaanka. Naqshadan  bilaa daadsan  macnaheedu waa eber daadad inta lagu jiro isku xirka iyo kala goynta labadaba, xitaa cadaadiska ku soo wajahan xadka la qiimeeyay.

TS EN ISO 15171  Isku-xireyaasha tijaabada ah waxay u hoggaansamaan  ISO 15171-1  (cabbirka iyo shuruudaha waxqabadka ee dhibcaha tijaabada) iyo  15171-2  TS Heerarkan caalamiga ahi waxa uu hubinayaa isdhaafsiga cabbirka ee soo saarayaasha - isla tuubada tijaabada ayaa ku haboon isku xidhka Parker, Stauff, Hydac, Minimess, iyo kuwa kale.

Xaaladaha isticmaalka caadiga ah:

• Jeegaga komishanka  - Hubi cadaadiska nidaamka marka la bilaabayo

• Korjoogteynta joogtada ah  - Baaritaan degdeg ah iyada oo aan la joojin wax soo saarka

• Muunad dareere ah  - Soo saar saambalo saliid si loo baaro wasakhda

• Neefsashada nidaamka  - Sii daaya hawada ku xayiran dayactirka ka dib

• Cilad-sheegid  - Ogow cilladaha cadaadiska wakhtiga dhabta ah

Tilmaamaha Muhiimka ah

Isku xirka Dekedda iyo Farsamaynta Seal

Qaybtani waxay ka hadlaysaa labada go'aannada injineernimada ee ugu muhiimsan: sida isku xidhku ugu xidhmo wareeggaaga, iyo waxa cadaadiska ku xidhaya.

Ikhtiyaarada cabbirka dunta

Isku-xidhku wuxuu si toos ah ugu xidhaa deked la taabtay oo ku taal mashiinnada biyaha, dhululubada, ama block-ga valve. Ku dhig dunta dekedda jirta - dunta aan is-qabin waxay sababaan dillaac iyo dhaawac labadaba.

M16x2  waa cabbirka kaliya ee inta badan la dalbado ee codsiyada warshadaha guud.  G1/4  iyo  G1/2  waxay ku badan yihiin gobollada ay BSP duntu ka tahay caadada (UK, Commonwealth, dhirta Yurub ka weyn).

Mechanism Seal Internal

Hawlgalka bilaa dareere ah wuxuu ku tiirsan yahay waalka poppet-ka ee saxan ee ku jira jidhka isku xidhka:

1. Marka la nasanayo  - Boob-guga-raar ah ayaa ku xiraya kursiga gudaha. Cadaadiska nidaamka ayaa si adag u haya poppet-ka oo xiran.

2. Isku xirka  - Dhamaadka tuubada tijaabada mating (sida ISO 15171-2) waxay hoos u dhigtaa poppet, furitaanka marinka cabbirkaaga ama muunadeeyaha. Shaabada u dhaxaysa dhamaadka tuubada iyo daloolka isku xidhka ayaa ka hortagaya daadinta dibadda.

3. Goynta  - Marka dhamaadka tuubada ka baxdo, xoogga guga ayaa isla markiiba xira poppet. Saliida hadhaaga ah ee dekeddu waxay ku sii jirtaa gudaha - eber dhibicyo.

Xarunta shaabadaysan (NBR, FKM, EPDM, ama kuleyl hoose) ayaa sameeya xayndaabka koowaad ee u dhexeeya poppet iyo kursiga, oo lagu daray xayndaabka labaad ee u dhexeeya tuubada dhamaadka tuubada iyo daloolka gudaha ee isku xidhka. Doorashada alaabta saxda ah ee heerkulka dareerahaaga iyo kiimikada ayaa lagu daboolay hagaha xulashada  hoose.

Maxaad u dooratay 630-ka Bar ee Isku-xidhaha Imtixaanka?

630 Bar - Xadka La tijaabiyay, Maahan Suuqgeyn

630 bar (9,135 psi) waa cadaadiska shaqada ee la xaqiijiyay marka loo eego borotokoolka tijaabada ISO 15171-1. Habayn kastaa waxa la mariyaa tijaabada cadaadiska wareegtada iyo xaqiijinta-cadaynta ka hor inta aan lagu sii dayn kaydka.

Afar Qalab, Afar Daaqadaha Ka Shaqeeya

Nidaamyada haydarooliga ee kala duwan waxay ku shaqeeyaan dareere kala duwan heerkul kala duwan. Hal xarun oo shaabadaysan ma dabooli karto dhammaan shuruudaha:

• NBR (code N)  - Dheecaannada haydarooliga macdanta-saliida ilaa 100 °C. Kharash wax ku ool ah oo loogu talagalay ~ 70% codsiyada warshadaha.

• FKM (code F)  - Heerkulka sare ilaa 200 °C. Sidoo kale waxa ay gacanta ku haysaa dareerayaasha phosphate-ester u adkaysta dabka. Iska caabin wanaagsan oo kiimiko ah oo lid ku ah waxyaabaha gardarrada ah.

• EPDM (code E)  - Steam, dareeraha biriiga (DOT 3/4), biyaha-glycol, iyo dareerayaasha synthetic polar. Heerkulku wuxuu gaaraa ilaa -40 °C. Aan ku habboonayn saliidaha batroolka.

• Heer-ku-hooseeya (code L)  - Iskudhis heerkiisu sarreeyo oo lagu qiimeeyay -50 °C. Loo isticmaalo qalabka mobilada arctic, nidaamyada hawo-qabow ee kaydinta qaboobaha, iyo wareegyada caawinta LNG. Lagu heli karo codsi.

Xulashada shaabada khaldan waa sababta #1 ee fashilka hore. Kaydinta $0.30 ee xulashada shaambada waxay ku kici kartaa kumanyaal wakhti dhimis aan la qorshayn.

Iska caabinta Daxalka ee u dhigma Deegaanka

• Zinc-plated (code Z)  - Ku filan meelaha kulul ee gudaha ee leh huurka la xakameeyey. Laguma talinayo soo-gaadhista bannaanka.

• Zinc Nickel CrVI-free (code N)  - 500+ saacadood iska caabin milix ah halkii ASTM B117. U hoggaansan si buuxda REACH Doorashada caadiga ah ee shixnadaha Yurub iyo rakibaadda dibadda

• Birta Aan-la-aanta ah 304 (code F)  - Iska caabbinta daxalka guud ee wanaagsan. Ku habboon aagagga u dhow ee cuntada laga soo saaro iyo jawiyada wasakhaysan.

• Birta Aan-la-aanta lahayn 316L (koodka L)  - Molybdenum-la xoojiyay. Waxa ugu fiican bey'ada badda, meelaha xeebaha ah, meelaha kiimikada lagu dhaqo, iyo meel kasta oo chlorides ama milix ay joogaan.

Koofiyadaha Ilaalinta ee La Jooga Cutubka

Ka-hortagga gariirka O-Ring Option

Qalabka ordaya gariir joogto ah (matoorada bistoonka>5 Hz, kombaresarada naaftada, qodayaasha raadraaca) waxay si tartiib tartiib ah u dabciyaan xirmooyinka dunta leh ee boqolaal saacadood oo shaqo ah. Ku darista ka-hortagga gariirka O-ring (code  1) waxay abuurtaa quful makaanikada labaad. Korodhka qiimaha ayaa ah mid aad u yar - helitaanka isku halaynta goobta ayaa ah mid muhiim ah.

Habaynta Tirada Qaybta

Isku xidh kasta oo tijaabo ah waxa loo dhisay kood lix qaybood ah:

Dusha sare - Shaabad - Dabool - Taxane - O-ring - Calaamadeynta

Z - N - R - TC - 0 - 0
│ │ │ │ │ └─ 0 = Midna / XX = Calaamadda ganacsiga
│ │ │ │ = └─── 1 O-ring
│ │ │ └───────── TC = Taxanaha Isku-xidhka Imtixaanka
│ │ └────────────────── W = Midna / H = Hex / R = Wareeg / E = Universal / P = Caag
│ └────────────────────── N = NBR / F = FKM / E = EPDM / L = Low-temp
└───────────────────────────────────── Z = Zinc- / N = 3 Midabka Madoow / N = 3 / L = 316LS

Tusaalooyinka Habaynta

Sida loo doorto Isku-xidhka Imtixaankaaga

1. Aqoonso dunta dekedda  ee qaybtaada hawo-mareenada. Ku hubi sawirka ama ku cabbir cabbir dunta. Inta badan:  M16x2 , M10x1 , G1/4 , ama  G1/2.

2. Xaqiiji cadaadiska nidaamkaaga ugu sarreeya . Haddii ay dhaafto 630 bar, u gudub fasalka ku habboonaanta heerka sare.

3. Ku dheji shaabadda iyo dareerahaaga iyo heerkulkaaga . Saliida macdanta ee ka yar 80 °C → NBR. Ka sarreeya 100 °C ama dareere u adkaysta dabka → FKM. Dareeraha biriiga, uumiga, ama synthetics polar → EPDM. Ka hooseeya -40 °C → codso kuleyl hoose.

4. Dooro biraha jirka oo ku saleysan deegaanka . Gudaha engegan → bir ka samaysan zinc. Banaanka/ badda/dhaqashada → 316L SS. Dhoofinta Yurub → Zn-Ni CrVI-free sida gundhig ahaan.

5. Ku dar ikhtiyaarada shaqeynta . Koofida silsilad-ku-xiran ee adeegga goobta. Ka-hortagga gariirka O-ring ee mashiinnada wareegta ama isku-celinta. Koofida caalamiga ah haddii loo baahan yahay awoodda hawo-qaadista.

6. Caddayn tirada iyo wakhtiga loo baahan yahay . Habaynta caadiga ah waxay u rabtaa si ka dhakhso badan dufcadaha calaamadaysan.

Haddii aadan hubin wax halbeeg ah, noo soo dir sawirka dekedda jira iyo qoraal ku saabsan xaaladahaaga shaqo - waxaan kugula talineynaa qaabeynta saxda ah.

Hagaha Rakibaadda

1. Diyaari dekedda.  Ku nadiifi daloolka dunta leh dareere. Ka saar burburka, dunta duugta ah, iyo burburka. Deked wasakhaysan waxay sababtaa burburka rakibaadda iyo daadinta rakibidda ka dib.

2. Si sax ah u codso dunta dunta.  Isticmaal sharooto PTFE (2-3 duub, arrimaha jihada) ama dareere anaerobic ah oo lagu qiimeeyay 630 bar. Si xad dhaaf ah ha u dalban - shaandhaynta xad-dhaafka ah waxay geli kartaa wareegga biyaha oo waxay sumayn kartaa saliidda.

3. Torque ilaa qeexid.  Gacmaha- adkee marka hore, ka dibna mari torque adigoo isticmaalaya qiyamka hoose. Weligaa ha u isticmaalin furayaasha saamaynta ku leh isku xidhka tijaabada - waxay wax ka beddelaan kursiga poppet ee gudaha.

4. Ku dheji daboolka ilaalinta.  Daboolka ha shido mar kasta oo aan barta tijaabada la isticmaalin. Boodhka iyo dhogorta dusha sare ee poppet ee gudaha ayaa sababa dhibcaha iyo daadinta aakhirka.

5. Cadaadis-tijaabi ka hor inta aan la dirin.  Keen nidaamka cadaadiska shaqada oo hubi isku-xidhka jirka iyo dekedda si aad u ooyaan. Hagaajin hadda halkii aad ka ahaan lahayd inta lagu jiro wax soo saarka.

Codsiyada caadiga ah

Su'aalaha Inta Badan La Isweydiiyo

Isku xirka 630 bar tijaabinta ma xamili karaa adeega gaaska?

Naqshadeynta heerka ISO 15171 waxaa loogu habeeyay saliidaha hydraulic iyo dareerayaasha macdanta ku saleysan. Hawo cufan ama warbaahin kale oo gaas ah, joomatari xidhidhiyaha guduhu waxa laga yaabaa in aanu bixin wax-qabad ku filan oo ka caagan gaasaska oo yaraada awgeed. Haddii codsigaagu uu ku lug leeyahay adeegga gaaska, caddee tan wakhtiga la dalbashada si aanu u qiimayno xeryahooda shaabadaysan oo beddelka ah oo aan u xaqiijinno ku habboonaanta walxaha jidhka ee cadaadiskaaga hawlgalka gaarka ah.

Waa maxay faraqa u dhexeeya 304 iyo 316L ahama birta ah ee isku xidhka tijaabada?

Farqiga ugu weyni waa maadada molybdenum. 304 SS waxa uu leeyahay ku dhawaad ​​18% chromium iyo 8% nikkel, kaas oo siinaya caabbinta daxalka guud ee deegaanka gudaha ee engegan qiimo jaban. 316L SS wuxuu ku daraa 2-3% molybdenum, taas oo si weyn u wanaajisa iska caabbinta xayndaabka chloride-ka iyo daxalka dillaaca. Deegaannada badda, rakibaadda xeebaha, meelaha kiimikada lagu dhaqo, ama codsi kasta oo lagu buufiyo milixdu ama milixyada baraf-ka-jaridda, 316L ayaa ah doorashada lagu taliyey in kasta oo qiimaha alaabtu sareeyo.

Miyaan heli karaa calaamado gaar ah oo ku xardhan isku xidhka imtixaanada?

Haa Adeegso summada XX ee xadhkaha qaybta oo soo gudbi faylka astaantaada vector (qaabka AI/EPS/PDF waa la door biday). Calaamaddu waxay ku xardhan tahay laysarka cutub kasta ka hor inta aan la rarin. Cabbirka dufcadda ugu yar ee calaamadaynta caadada ah waxay ku kala duwan tahay wadarta habka mugga - caadi ahaan la heli karo laga bilaabo 50 unug SKU kasta.

Miyaan u baahanahay O-ring-ka-hortagga gariir kasta ee isku xidhka imtixaan kasta?

Had iyo jeer maaha. O-ring-ga-gariir-ka-hortagga ah (code 1 ee lambarka qaybta) wuxuu ku darayaa sifo haynta labaad ee u dhexeeya jirka ku habboon iyo gelinta dunta. Waxaa si xoog leh loogu talinayaa qalabka la kulma gariir joogto ah oo ka sarreeya 5 Hz - sida bamamka piston-ka, kombaresarada naaftada, qodista mobaylada, ama nidaamyada gaadiidka gariiraya. Rakibaadaha taagan sida istaarooyinka shaybaadhka ama mashiinada jaraa'id ee taagan, nooca caadiga ah ee aan lahayn O-ring ayaa caadi ahaan ku filan.

Waa kuwee xajmiyada dunta ee loo heli karo 630 xidhmooyinka tijaabada ah?

Helitaanka caadiga ah wuxuu daboolayaa dunta metric M10x1, M12x1.5, M14x1.5, M16x2, M18x1.5, iyo BSP threads barbar G1/4, G3/8, G1/2. Cabbirrada ugu badan ee la cayimay waa M10x1 (wareegyada is haysta), M16x2 (Haydaroogayaasha warshadaha caadiga ah), iyo G1/2 (nidaamyada socodka sare). Mawduucyada gaarka ah ee ka baxsan noocyadan waa la soo saari karaa iyadoo loo eegayo tirada sida ugu yar.

Sideen ku dooran karaa shaabadda saxda ah ee nidaamka hydraulicka?

Ka bilow nooca dareerahaaga dhabta ah iyo heerkulka ugu sarreeya ee hawlgalka. NBR waxay u shaqeysaa dareerayaasha haydarooliga ee saliidda ku saleysan ilaa 100 °C - tani waxay dabooshaa qiyaastii 70% codsiyada warshadaha waana ikhtiyaarka ugu hooseeya. U beddelo FKM haddii nidaamkaagu ka sarreeyo 100 °C ama uu isticmaalo dareeraha phosphate ester (dabka u adkaysta). Dooro EPDM haddii aad ku shaqeyso dareeraha biriiga, uumiga, isku darka biyaha-glycol, ama synthetics polar. Deegaannada arctic ama cryogenic ee ka hooseeya -40 °C, codso xarunta kulaylka yar. Ku socodsiinta shaabadda khaldan ee habka kulaylka sare waa sababta ugu weyn ee daadinta dhicis ah.

Zinc nickel CrVI-daaqsin la'aan ma looga baahan yahay suuqyada Yurub?

Si adag sharcigu ugama baahna dhammaan alaabooyinka, laakiin si weyn ayaa loogu taliyay. Xeerarka EU REACH (EC) Maya 1907/2006 ayaa xaddidaya chromium hexavalent marka la dhammeeyo dusha sare. Dajinta caadiga ah ee zinc waxa ay inta badan ka kooban tahay raadraaca Cr(VI) lakabyada passivation. Dasinnada-free Zinc Nickel CrVI waxay meesha ka saaraysaa khatarta u hoggaansanaanta gebi ahaanba iyadoo la bixinayo 500+ saacadood oo caabbinta milixda ah halkii ASTM B117 - aad uga fiican zinc-ga caadiga ah. Alaab kasta oo loo soo raro EU, CrVI-free waa talada ugu talagalka ah.

Waa maxay ISO 15171 iyo maxay muhiim ugu tahay isku dhafka tijaabada?

ISO 15171 waa halbeeg caalami ah oo si gaar ah u daboolaya isku dhafka tijaabada hydraulic si loogu isticmaalo nidaamyada tamarta dareeraha. Qaybta 1 (ISO 15171-1) waxay qeexaysaa cabbirada, shuruudaha waxqabadka, iyo hababka tijaabada ee isku dhafka tijaabada. Qeybta 2 (ISO 15171-2) waxay dabooshaa xirmooyinka dhamaadka tuubada tijaabada. U hoggaansanaanta macneheedu waxa weeye badeecaddu waxay la kulmeysaa is beddelka cabbirka iyo cabbirrada cabbirka cadaadiska caalamiga ah ee la aqoonsan yahay - waa muhiim marka qalabkaaga tijaabada uu u baahan yahay inuu la xiriiro qaybaha soo saarayaasha kala duwan. Alaabooyinka la kulma ISO 15171 waxaa mararka qaarkood loogu yeeraa warshadaha sida 'isku-xirnaanta ogaanshaha' ama 'qaabka yar-yar'.
