Ukuze uthole uxhumano lwe-flange olungavuzi, ukufakwa kwe-gasket okufanele kuyadingeka, amabhawodi kufanele anikezwe ukushuba kwebhawodi okulungile, futhi amandla ebhawodi aphelele kufanele ahlukaniswe ngokulinganayo phezu kobuso bonke be-flange.

Ngokuqiniswa kwe-Torque (ukusetshenziswa kokulayisha kuqala kusixhumi ngokuphendula nati lesixhumi) ukungezwani okufanele kwebhawodi kungenziwa.

Ukuqiniswa okulungile kwebhawodi kusho ukusebenzisa kahle kakhulu izakhiwo zokunwebeka zebhawodi. Ukuze isebenze kahle, ibhawodi kufanele liziphathe njengesiphethu. Ekusebenzeni, inqubo yokuqinisa yenza i-axial pre-load tension kubhawodi. Lo mthwalo we-tension uyalingana futhi uphambene namandla okucindezela asetshenziswa ezingxenyeni ezihlanganisiwe. Kungabizwa ngokuthi "umthwalo oqinisayo" noma "umthwalo wengcindezi"

I-torque wrench

I-Torque Wrench yigama elijwayelekile lethuluzi lokujiya eliqondiswa ngesandla, futhi lisetshenziselwa ukusetha ngokunembile amandla okubopha njengenadi noma ibhawudi. Ivumela opharetha ukuthi alinganise amandla ajikelezayo (i-torque) asetshenziswe kubhawodi ukuze ifaniswe nezicaciso.

Isikrufu semanuwali kanye ne-hydraulic

Ukukhethwa kwendlela yokuqinisa ibhawudi ye-flange efanele kudinga ulwazi. Ukusetshenziswa ngempumelelo kwanoma iyiphi inqubo kudinga ukufaneleka kwakho kokubili amathuluzi azosetshenziswa kanye neqembu elizokwenza umsebenzi. Okulandelayo kufingqa izindlela ezivame ukusetshenziswa kakhulu zokuqinisa ibhawudi ye-flange.

• I-Wrench Manual
• Impact Wrench
• I-Hammer Wrench
• I-Hydraulic Torque Wrench
• I-Manual Beam kanye ne-Gear-Assisted Torque Wrench
• I-Hydraulic Bolt Tensioner

Ukulahleka kwe-torque

Ukulahleka kwetorque kungokwemvelo kunoma yiliphi ilunga eliboshiwe. Imiphumela ehlanganisiwe yokuphumula kwebholithi, (cishe u-10% phakathi namahora angu-24 okuqala ngemva kokufakwa), ukukhasa kwe-gasket, ukudlidliza ohlelweni, ukunwetshwa kokushisa kanye nokusebenzisana okunwebekayo ngesikhathi sokuqinisa ibhawudi kunomthelela ekulahlekeni kwetorque. Lapho ukulahlekelwa kwetorque kufinyelela ngokwedlulele, ingcindezi yangaphakathi idlula amandla acindezelayo abambe i-gasket endaweni futhi kwenzeka ukuvuza noma ukuphuma.

Isihluthulelo sokunciphisa le miphumela ukufakwa okufanele kwe-gasket. Ngokuhlanganisa ama-flange ndawonye kancane futhi ngokuhambisana lapho ufaka i-gasket futhi uthatha okungenani amaphasi amane okuqinisa amabhawodi, ngokulandela ukulandelana kokuqina kokuqina kwebhawodi, kuba nenkokhelo ezindlekweni zokunakekela ezincishisiwe kanye nokuphepha okwandisiwe.

Ukujiya okufanele kwe-gasket nakho kubalulekile. Uma i-gasket ishubile, i-gasket ikhuphuka phezulu, okungaholela ekulahlekeni kwe-torque. Kumaflange obuso ajwayelekile e-ASME, kuvame ukutuswa i-gasket engu-1.6 mm obukhulu. Izinto ezisetshenziswayo ze-gasket ezincanyana zingathatha umthwalo we-gasket ophezulu futhi ngenxa yalokho nezingcindezi zangaphakathi eziphezulu.

Ukugcoba kunciphisa ukungqubuzana

Ukugcotshwa kunciphisa ukungqubuzana ngesikhathi sokuqina, kunciphisa ukwehluleka kwebhawodi ngesikhathi sokufakwa futhi kwandisa impilo yebhawodi. Ukwehluka kwama-coefficients wokungqubuzana kuthinta inani lokulayisha kuqala elizuzwe ngetorque ethile. Ukungqubuzana okuphezulu kubangela ukuguqulwa okuncane kwetorque ukuze ilayishe kuqala. Inani le-coefficient yokungqubuzana elihlinzekwe ngumkhiqizi wezigcobo kufanele laziwe ukuze liqinisekise ngokunembile inani letorque elidingekayo.

Izinto zokuthambisa noma zokulwa nokuthunjwa kufanele zisetshenziswe kukho kokubili indawo ethwala amantongomane kanye nezintambo zesilisa.

Ukuqinisa ukulandelana

Iphasi yokuqala, qinisa kancane ibhawodi lokuqala bese udlulela ngqo ngaphesheya noma amadigri angu-180 ngebhawodi yesibili, bese unyakazisa1/4 ujike indilinga noma amadigri angu-90 ngebhawodi lesithathu futhi uwele ngokuqondile okwesine. Qhubeka nalokhu kulandelana kuze kuqiniswe wonke amabhawodi.
Uma uqinisa i-flange ene-bolt, sebenzisa iphethini ye-criss-cross.

Ukulandelana kokuqinisa

Ukulungiselela i-flange bolt-up

Ekuxhumekeni kwe-flanged, zonke izingxenye kufanele zilungile ukuze kutholakale uphawu. Isizathu esivame kakhulu sokuvuza kwamajoyinti afakwe i-gasket izinqubo zokufaka ezingafanele.

Ngaphambi kokuqala inqubo yokubhowula, izinyathelo zokuqala ezilandelayo zizogwema izinkinga ezizayo:

• Hlanza ubuso be-flange futhi uhlole izibazi; ubuso kufanele buhlanzeke futhi bungabi nasici (ama-burrs, imigodi, ama-dents, njll.).
• Hlola ngokubuka wonke amabhawodi namantongomane ukuze uthole izintambo ezilimele noma ezigqwalile. Shintsha noma ulungise amabhawodi noma amantongomane njengoba kudingeka.
• Susa ama-burrs kuzo zonke izintambo.
• Gcoba imicu yebhawodi noma ye-stud, futhi ubuso benati buncikene ne-flange noma iwasha. Amawasha aqinile ayanconywa ezinhlelweni eziningi.
• Faka i-gasket entsha futhi uqiniseke ukuthi i-gasket igxile kahle. UNGASEBENZISA KABUSHA i-gasket endala, noma usebenzise ama-gasket AMANINGI.
• Hlola ukuqondanisa kwe-flange ASME B31.3 Inqubo Yokufaka Amapayipi:
  …ubuso be-flange kufanele buhambisane phakathi kuka-1/16″ ngonyawo ngalunye lobubanzi, futhi izimbobo zebhawudi ye-flange kufanele ziqondaniswe phakathi kokungu-1/8″ okuphezulu kokusuka.
• Lungisa ukuma kwamantongomane ukuze uqinisekise ukuthi imicu engu-2-3 ibonakala ngaphezu kwentongomane.

Kungakhathaliseki ukuthi iyiphi indlela yokuqinisa esetshenziswayo, ukuhlolwa okunqunyiwe ngenhla kanye namalungiselelo kufanele kwenziwe njalo.

Eyami isipiliyoni mayelana…I-Torque Wrenches

• Esikhathini esedlule ngihlanganise amakhulukhulu ezixhumanisi ze-flange ezingavuzi, kusukela ku-NPS 1/2 kuya ku-NPS 24 nangaphezulu. Akuvamile ukuthi ngisebenzise i-Torque Wrench.
  Empeleni, ukuxhunywa kwe-pipe flange "okujwayelekile" cishe akukaze kuhlanganiswe ne-Torque Wrench. Ukuxhumana okunzima kakhulu kimi kwakuhlale "kwabancane" futhi ikakhulukazi uhlobo lwe-Raised Face ngaphezu kwe-Class 300 (RF Height = cishe u-6.4 mm).
  Ubuso be-flange obuhlobene obuvela ku-NPS 1/2 flange buncane ke isibonelo i-NPS 6 flange, futhi ithuba lokungaqondi kahle, ngokubona kwami ​​​​likhulu kakhulu.
  Ngokwenza njalo ngihlangabezana nokuxhumeka kwe-flange njalo, lapho ukuqondana kungabi emkhawulweni wokubekezelelana. Uma nje i-oda leNqubo Yokuqinisa ilandelwa umakhenikha akamatasatasa kahle. Kungenzeka ukuthi kuqalwe ngebhawodi lesithupha esikhundleni sebhawodi elilodwa. Sebenzisa amehlo akho ngesikhathi sokuhlanganisa i-flange, kubaluleke kakhulu futhi kunomthelela omkhulu ekuxhumekeni okungavuzi

Ukuxhumeka okungalungile kwe-flange - amabhawodi mafushane kakhulu!

Yini ongayenza?

• Isithombe sibonisa i-flange eboshwe ngokungafanele, ngoba ama-bolts amabili mafushane kakhulu, futhi amantongomane awekho ngokuphelele kuma-bolts. Lokhu kusho ukuthi ilunga lingase lingabi namandla ngendlela okufanele libe ngayo. Ama-flange aklanywe ngendlela yokuthi yonke inhlanganisela ye-nut-bolt ibambe amandla ku-flange. Uma inathi liboshwe kancane kubhawodi, ukuxhumana kungase kungabi namandla ngokwanele.
• Uma umsebenzi wakho uhlanganisa ukuhlanganisa izinto zokusebenza, ukuhlanganisa amapayipi avulekile, izimbobo zomgodi wokubhowula noma okunye ukuxhuma okuboshiwe emishinini, noma okunye ukuhlanganisa imishini, khumbula ukuthi umsebenzi awukaqedi kuze kube yilapho wonke amabhawodi efakwe kahle futhi aqiniswa.
• Eminye imishini idinga izinqubo ezikhethekile zokuqinisa amabhawodi. Isibonelo, kungase kudingeke usebenzise isikrufu se-torque ukuze uqinise amabhawodi ngendlela efanele, noma uqinise amabhawodi ngendlela ekhethekile. Qiniseka ukuthi ulandela inqubo efanele, sebenzisa amathuluzi afanele, nokuthi uqeqeshwe kahle ngenqubo yokuhlanganisa imishini.
• Hlola amapayipi nezinto zokusebenza ukuze uthole ama-flange aboshwe kahle njengengxenye yokuhlola ukuphepha kwezitshalo zakho. Njengesiqondiso esilula, amabhawodi angadluleli ngalé kwamantongomane kufanele abuyekezwe ingcweti yamapayipi ezitshalo noma unjiniyela.
• Uma ubona ama-flange aboshwe ngokungafanele esitshalweni sakho, zibike ukuze zilungiswe, futhi uqinisekise ukuthi ukulungiswa okudingekayo kuqediwe.
• Hlola okokusebenza okusha, noma okokusebenza okuhlanganiswe kabusha ngemva kokulungiswa, ukuze uqiniseke ukuthi kuhlanganiswe kahle futhi kufakwe ibhawudi ngendlela efanele ngaphambi kokuqala.

Bungakanani ubude obufanele be-Stud Bolt?
Njengomthetho, ungasebenzisa: Imicu yamahhala yebhawodi ngaphezulu kwentongomane ilingana nezikhathi eziyi-1/3 zobubanzi bebhawodi.
