Xulashada Waalka Heerkulka Sare: Waalka Kubbadda ee PPL iyo kuwa Birta ku fadhiya ee loogu talagalay Saliidda Kulaylka iyo Nidaamyada Uumiga

1. Caqabadda Heerkulka Sare

Hawlgallada wareegyada saliidda kuleylka ama shabakadaha qaybinta uumiga ee cadaadiska sare leh ayaa ka mid ah waajibaadka ugu ciqaabta badan ee kastawaalka kubbadda heerkulka sare lehMarka heerkulka hab-socodku u dhexeeyo 200°C ilaa 550°C, waalka caadiga ah si dhakhso ah ayuu u burburaa—oo si qaali ah ayuu u dhacaa.

Wareegga kulaylka wuxuu keenaa cadaadis farsamo oo aan kala go 'lahayn oo ku yimaada qaybaha gudaha. Kuraasta jilicsan ee caadiga ah (PTFE saafi ah ama RPTFE galaas ku jira) waxay bilaabaan inay soo baxaan, si joogto ah u soo gurguuraan, oo si joogto ah u beddeshaan heerkul ka sarreeya 180°C. Marka giraanta kursigu lumiso xasilloonida cabbirka, uumi-baxa ayaa dhaca ama saliidda kulaylka ayaa ku daadata godka jirka, taasoo abuurta khataro badbaado iyo xidhitaan aan la qorshayn.

Haddana xad-dhaaf ah ma aha jawaabta. Kooxo badan oo wax soo iibsi ayaa si dareen leh u doorta waalka birta ku fadhiya adeeg kasta oo ka sarreeya 200°C, iyagoo u maleynaya inay tahay wadada kaliya ee badbaadada leh. Tani waxay inta badan kordhisaa kharashka raasumaalka iyadoo la adeegsanayo300%–400%iyada oo aan la keenin faa'iidooyin dhab ah oo loogu talagalay codsiyada heerkulka dhexdhexaadka ah.

Meesha ugu macaan ee injineernimada waxay ku jirtaa fahamka xuduudda u dhaxaysaKuraasta jilicsan ee PPL (Polyphenylene Phenylate)iyokuraasta birta ah ee wejiga adag- dheelitirka shaabadaynta eber-daadinta, isku halaynta muddada-dheer, iyo miisaaniyadda mashruuca.

3. Kuraasta PPL: Meesha Macaana ee 200–280°C

Waa maxay PPL?

PPL (Polyphenylene Phenylate) waa thermoplastic waxqabad sare leh oo loo sameeyay adkeysi kuleyl oo sarreeya. Si ka duwan PTFE (wuxuu jilciyaa 180°C) ama RPTFE (oo ku xaddidan 220°C), PPL waxay ilaalisaa adkaanta farsamada, xoogga cadaadiska, iyo iska caabbinta gurguurta ilaa280°C.

Codsiyada Ku Habboon

• Nidaamyada uumiga ee buuxa- cinwaanada ugu muhiimsan iyo khadadka laamaha ilaa Fasalka 300/600.
• Wareegyada saliidda kulaylka– wareegyada beddelaha kulaylka iyadoo la adeegsanayo dareere macdan ah ama macdan ah (tusaale ahaan, Dowtherm™, Therminol®) oo ka hooseeya 280°C.
• Biyaha kuleyliyaha- biyo kulul oo cadaadis sare leh oo u baahan xidhitaan adag.

Maxaad u dooran lahayd PPL Kuraas bir ah oo ka duwan kuraasta birta ah ee aaggan?

1. Shaabad adag oo dhab ah– Xusuusta dabacsan ee PPL waxay u oggolaanaysaa API 598 Heerka A eber daadasho; kuraasta birta ah waxay si dabiici ah u oggolaanayaan in qaar ka mid ah ay daadasho.
2. Keydinta kharashka badan- Qalabka PPL ee 4-inch Class 300 trunnion badanaa wuu ku kacayaa60% ka yarmarka loo eego u dhiganta birta ku dheggan.
3. Kharashyada dhaqdhaqaaqa oo hooseeya- is jiidjiid hoose wuxuu yareeyaa cabbirka dhaqdhaqaaqa, isagoo badbaadinaya isku-darka simbiriirixan.

4. Kuraasta Birta ah: Marka Heerkulku ka bato 280°C

Tiknoolajiyadda Hard-Facing

Ka sarreeya 280°C, kuraasta birta ah oo keliya ayaa badbaaday. Adkaynta sare ee dusha sare waa lama huraan:

• Stellite® (ku salaysan kobalt)- shoog kuleyl oo aad u fiican iyo iska caabin cuncun leh, oo ku habboon uumiga.
• Karbohaydrayt Chrome ah oo loo marayo HVOF- adkaansho 68–70 HRC, oo aan u adkeysan karin walxaha xoqaya ee saliidda kulaylka.
• Kaarboohaydrayt Tungsten ah- iska caabin xad dhaaf ah oo xirasho ah ilaa 400 ° C.

Magdhawga Gu'ga ee Belleville

Ballaarinta kulaylka waa caqabad muhiim ah. Inta lagu jiro bilowga kulul, kubbadu si ka dhaqso badan ayay u fidaysaa marka loo eego jirka. Naqshadaha heerkulka sare ee xirfadeed waxay ku jiraanKuraasta Belleville ee guga lagu rarokuwaas oo ilaaliya cadaadiska shaabadeynta iyadoo u oggolaanaya dhaqdhaqaaqa axial inuu la qabsado shoogga kulaylka.

Adeegyada Caadiga ah (>280°C)

• Tuubooyinka uumiga ee aadka u kulul ee warshadaha korontada.
• Foornooyinka dillaaca kiimikada batroolka iyo kulaylinta laamiga (300–450°C).
• Khadad kiciyayaal ah oo xoqan oo leh adkaha la tababaray.

5. Qodobbada Naqshadeynta Injineerinka ee Muhiimka ah ee Saliidda Kulaylka iyo Uumiga

Qalabka kursiga waa kala bar sheekada. Arrimahan labaad waa kuwo si isku mid ah muhiim u ah:

1. Xididka Ka-hortagga Baakadaha iyo Baakadaha Tooska ah

Wareegga kulaylka ayaa waqti ka dib debciya baakadaha garaafitka caadiga ah.Baakad toos ah oo la rarayoIyada oo la adeegsanayo dhaqayaasha Belleville oo si joogto ah u cadaadiya faraantiga garaafka, iyagoo ilaalinaya xoogga shaabadda iyada oo aan la adkeyn gacanta.

2. Gargaarka Cadaadiska Godadka (Muhiim u ah Saliidda Kulaylka)

Dareeraha kuleylku si weyn ayuu u fidaa marka uu ku xayirmo godka jirka ee xiran. Haddii aan la helin gargaar, cadaadisku wuxuu burburin karaa jirka ama wuxuu qarxin karaa kuraasta. Cadeekuraas is-dejisa(saameyn bistool ah oo keliya) ama godad isle'eg gudaha ah.

3. Naqshad Dab-badbaado leh (API 607 ​​/ ISO 10497)

Saliidaha kulaylka ee guban kara, waalka dabka badbaadiya waxaa ku jira shaabad labaad oo bir-ilaa-birta ah. Haddii kursiga PPL uu gubto inta lagu jiro dab, cadaadiska xariiqda ayaa kubadda ku riixaya bushimaha birta ah si loo xaddido daadinta hoose.

7. Liiska Hubinta 4-tallaabo ee Ka-soo-saarka Shiinaha

Marka laga soo iibsanayo waalka heerkulka sare lehShiinaha soo saaraha waalka kubadda, hubi in kooxdaada QA ay xaqiijiso heerarkan:

+----------------------------------------------------------------------+ | LIISKA HUBINTA KHUDBADDA KHAMRI-SILINTA HILIQADA SARE | +------------------------------------------------------------------------------------+ | [1] Hubi MTR-yada Agabka (EN 10204 3.1) ee jirka WCB/CF8M. | | [2] Waxay u baahan tahay tijaabooyin cadaadis heerkul sare ah iyo qolof ah sida ku cad API 598. | | [3] Hubi adkaanta dahaarka (≥68 HRC) ee Stellite/HVOF. | | [4] Kormeer baakadaha dhoofinta iyadoo la adeegsanayo daboolo flange ah oo ilaalinaya iyo qalab bir ah. | +------------------------------------------------------------------------------------+

Tallaabada 1 - Raad-raaca Agabka– Warbixinnada Tijaabada Warshadda ee Asaasiga ah oo leh lambarro kulayl ah oo lagu shaabadeeyay jirka (ASTM A216 WCB ama A351 CF8M).

Tallaabada 2 - Tijaabinta Heerkulka Sare– Baaritaannada biyaha ee caadiga ah ee deegaanka ayaa laga yaabaa inaysan muujin dhaqanka kursiga ee 250°C. Weydiiso tijaabooyinka gaaska kulul ama wareegga kulaylka ee qaybaha muunadaha.

Tallaabada 3 - Adkaanta Dahaadhka– Kuraasta birta ah, diiwaanka adag ee HVOF waa inuu muujiyaa ≥68−70 HRC si uu uga hortago xanaaqa iyo dhibcaha.

Tallaabada 4 - Dhoofinta Baakadaha– Sanduuqyo alwaax culus oo leh qalab xumbo gaar ah si looga hortago qaloocinta jirida inta lagu jiro rarista badda.
