Expansion sib koom
2021-06-25
Expansion Joint tseem hu ua yeeb nkab expansion sib koom ua ke, expansion sib koom ua ke, compensator thiab expansion joint. Kev sib koom tes nthuav dav yog ib yam khoom tshiab rau kev sib txuas ntawm cov twj, li qub, cov kav dej thiab lwm yam khoom siv nrog cov kav dej. Nws txuas nrog tag nrho bolts kom nws tag nrho, thiab muaj ib qho kev hloov pauv, uas yooj yim rau kev teeb tsa. Nws muaj peev xwm dais axial siab ntawm pipeline. Nyob rau hauv txoj kev no, lub installation thiab txij nkawm tuaj yeem hloov kho raws li qhov loj me ntawm qhov chaw teeb tsa. Thaum ua hauj lwm, nws tsis tsuas yog txhim kho kev ua hauj lwm efficiency, tab sis kuj plays lub luag hauj lwm nyob rau hauv kev tiv thaiv lub twj tso kua mis, li qub thiab lwm yam pipeline khoom. Daim ntawv kev sib txuas ntawm kev sib koom ua ke yog flange kev sib txuas, nrog ib sab flange thiab ib sab vuam. 1. Txhawb kev nthuav dav deformation tshwm sim los ntawm axial, transverse thiab angular cua sov ntawm lub raj xa dej. 2. nqus cov khoom vibration thiab txo cov khoom siv vibration ntawm cov kav dej. 3. Ncua qhov deformation ntawm cov raj xa dej los ntawm av qeeg thiab av qeeg. Vim tias cov cua sov nthuav dav thiab qhov txias txias ntawm cov raj xa dej, qhov kev ntxhov siab thiab thawb-rub lub zog ntawm cov yeeb nkab phab ntsa yuav raug tsim rau cov kav dej; Kev ntxhov siab ntawm cov yeeb nkab phab ntsa cuam tshuam rau lub zog ntawm cov yeeb nkab. Nrog rau qhov nce ntawm lub zog thawb-rub, qhov kev txhawb nqa ruaj khov ntawm cov yeeb nkab yuav tsum tau ua ntau yam los tuav lub zog thawb-rub los ntawm kev nthuav dav ntawm cov yeeb nkab; Yuav kom txo tau qhov kev ntxhov siab thiab thrust ntawm cov yeeb nkab phab ntsa, cov expansion sib koom them nyiaj yog siv.
