Kev soj ntsuam tsis tu ncua thiab kev ntsuas qhov xwm txheej
Nws raug nquahu kom ua qhov kev soj ntsuam pom txhua hli, tsom rau kev kuaj xyuas cov kab nrib pleb, deformation, lossis corrosion ntawm lub cev clamp. Rau siab - kub, siab - siab, los yog corrosive media ib puag ncig, qhov no yuav tsum tau luv luv rau kev soj ntsuam txhua lub lim tiam.
Tus qauv tshuaj xyuas yuav tsum xa mus rau GB / T 19228.3-2019 Pipe Supports thiab Hangers. Yog tias qhov tawg qhov tob tshaj 10% ntawm phab ntsa tuab lossis qhov deformation ntau dua 5% ntawm qhov loj me, lub clamp yuav tsum tau hloov tam sim ntawd.
Kev kho ib puag ncig tshwj xeeb: Nyob rau hauv cov xwm txheej ntawm kev vibration hnyav, lub laser rangefinder yuav tsum tau siv los kuaj xyuas qhov kev hloov pauv ntawm lub clamp, kom ntseeg tau tias qhov kev hloov pauv hloov tsis pub dhau ± 2 hli ntawm tus nqi tsim.
Ntxuav thiab tiv thaiv corrosion
Cov txheej txheem ntxuav siv cov tshuaj ntxuav tes nruab nrab nrog pH ntawm 6-8. Siv txhuam txhuam los so raws axial kev taw qhia ntawm lub clamp, tsis txhob khawb qhov chaw. Rau cov roj stains, chav purging nrog ib tug tshwj xeeb degreasing tus neeg sawv cev yuav siv tau, nrog rau qhov kub thiab txias ntawm 60 degrees.
Kev tiv thaiv corrosion yog raws li ISO 12944-2018 ib puag ncig corrosion kev faib tawm:
C3 (Medium corrosion): Kub-dip galvanizing, zinc txheej thickness Ntau dua los yog sib npaug rau 65μm
C4 (High corrosion): Epoxy zinc-nplua nuj primer + polyurethane topcoat, tag nrho cov zaj duab xis qhuav thickness Ntau dua los yog sib npaug rau 200μm
C5 (Marine ib puag ncig): 316L stainless hlau yeeb nkab clamps.
Lubrication thiab txij nkawm ntawm cov khoom txav
Lub voj voog lubrication: Siv cov roj molybdenum disulfide rau kev sib txuas bolted peb lub hlis twg, thiab txhaj lithium - roj raws li cov roj rau hauv cov khoom sib hloov.
torque tswj: Bolt preload yuav tsum tau raws li tus qauv tsim muaj nuj nqis thaum lub sij hawm installation, tswj siv lub torque wrench:
M12 bolts: 35-40 Nm
M16 bolts: 70-80Nm
M20 bolts: 120-140 Nm
Kev tiv thaiv kev vibration: Nyob rau hauv vibration zaus> 25Hz, roj hmab damping pads nrog ib tug tuab ntawm tsis tsawg tshaj li 10 hli yuav tsum tau ntsia.
