Dab tsi yog qhov txawv ntawm daim ntawv thov scenarios ntawm nyias txiv ntseej thiab hnyav hex ceev?
I. Nyias ceev (TSI 936/ wb 6172)
Cov yam ntxwv tseem ceeb
Nws tag nrho cov tuab tsuas yog ib nrab ntawm cov qauv hex txiv ntseej (DIN934), nrog cov khoom siv tsawg dua thiab qis profile.
Lub luag haujlwm tseem ceeb
1. txwv xauv &anti-loosing Secondary txiv ntseej(feem ntau siv)
Siv ua ke nrog cov txiv ntoo tseem ceeb: cov txiv ntoo tseem ceeb fastens lub workpiece, thaum lub txiv ntseej nyias yog nruj nreem tiv thaiv nws kom kaw cov xov thiab tiv thaiv kom tsis txhob xoob los ntawm kev co. Dav siv nyob rau hauv kev tsim kho machinery thiab pipeline flanges.
2. Rau qhov txwv ntsug installation qhov chaw
Hloov cov txiv ntseej txheem rau cov khoom siv nyias nyias, nyias- cov khoom siv phab ntsa, nqaim grooves thiab counterbores qhov twg tus qauv - tuab txiv ntseej tsis tuaj yeem haum.
3. Kev kho kom zoo & qhov chaw
Siv rau cov ntsia hlau, kho cov brackets thiab conveying mechanisms kom zoo -tune clearances thiab positioning nrug.
Daim ntawv thov Scenario
• Anti-loosing sib dhos rau hydraulic lub tog raj kheej pob qij txha thiab valve flanges
•Nqaim mounting txoj hauj lwm ntawm pwm thiab nyias - phab ntsa txee fixation
•Txwv tsis pub tso rau kis tau tus mob thiab cov ntsia hlau lead
•Nqaim installation cov ntsiab lus ntawm photovoltaic brackets
Qhov tsis zoo
Tsis tshua muaj siab thiab load- bearing peev. Nws tsis tuaj yeem nqa cov khoom hnyav ntawm nws tus kheej thiab yuav tsum tsis txhob siv los ua tus thawj fastening txiv ntoo ib leeg.
II. Heavy Hex Ceev (Thickened Hex Ceev, DIN6330)
Cov yam ntxwv tseem ceeb
Ntau thicker tshaj tus qauv lub teb chaws tus qauv ceev, muab ib tug ntev xov kev koom tes ntev.
Lub luag haujlwm tseem ceeb
1. Cov xov txuas ntev dua rau kev txhim kho load thiab tensile kuj
Ib lub xov tooj loj dua qhov chaw xa tawm kev ntxhov siab tsis sib xws, tiv thaiv cov xov slipping thiab puas. Ua ke nrog siab - lub zog studs ntawm Qib8.8, 10.9thiab12.9.
2. Haum rau hnyav -load thiab ntev - lub sij hawm vibration ua hauj lwm tej yam kev mob
Zoo tagnrho rau cov tshuab mining, ntauwd cranes, steel qauv, cov hlab ntsha siab thiab cov tshuaj flanges nyob rau hauv kev cuam tshuam tsis tu ncua thiab siab - zaus vibration.
3. Compensate los ua ke qhov khoob
Ua kom cov xov tsis muaj kev sib koom tes thaum cov txheej txheem ceev ncav cuag tag nrho vim yog tuab workpiece interlayers, stacked gaskets los yog loj reserved flange gaps.
Daim ntawv thov Scenario
• Sib tw studs (tus qauv haum rau cov kav dej, cov hlab ntsha siab thiab lub twj tso kua mis & valve flanges)
• Heavy- thauj khoom sib txuas rau kev tsim kho tshuab, ntauwd cranes thiab cov khoom nqa nqa
• Txhim kho cov choj hlau thiab cov khoom siv loj
• Siab - cov khoom siv tshuaj kub thiab siab - cov kav dej siab
Qhov tsis zoo
Nyob hauv qhov chaw ntsug loj, tsis haum rau cov khoom siv hnyav thiab compact, nrog cov nqi ntau lawm.
III. Kev sib piv ceev Core
1. Load Bearing Capacity
• Heavy hex ceev: Thawj qhov kev xaiv rau cov khoom hnyav, kev kub siab, kev co thiab kev ywj pheej fastening
• Cov txiv ntseej nyias: Tsuas yog rau kev txwv kev txwv thiab tiv thaiv -loosing, tsis tuaj yeem nqa cov khoom thauj ib leeg
2. Qhov chaw nruab
• Cov txiv ntseej nyias: txwv kev tshem tawm ntsug thiab nqaim kab noj hniav
• Hex txiv ntseej hnyav: Tsis muaj kev txwv qhov chaw ntsug, yuav tsum tau sib txuas xov ntev
3. Sib phim fasteners
• Cov txiv ntseej nyias: Ua ke nrog tus qauv hex taub hau bolts raws li qhov ntsuas thib ob
• Hex txiv ntseej: Standard matched studs thiab ntev siab -lub zog bolts
4. Tej yam sib dhos ua ke
• Anti-loosing set: Standard txiv ntseej + Nyias txiv ntoo
• Hnyav -lub luag haujlwm siab- siab flange: Stud bolt + Heavy hex txiv ntseej
Thov koj xav tiv tauj peb kom tau txais cov lus hais dawb yog tias koj xav tau cov txiv ntseej nyias, tus qauv hex ceev, hnyav hex txiv ntseej lossis lwm yam tshwj xeeb. Peb muab ntau yam ntawm fasteners rau manufacturers thoob plaws lub ntiaj teb no.
