Muaj ob hom grooved yeeb nkab fittings: saj zawg zog grooved couplings thiab rigid grooved couplings. Lawv txawv ntawm ob qho tib si tsos thiab kev ua haujlwm.
I. Qhov txawv txav
Flexible grooved couplings zoo nkaus li loj dua cov grooved couplings.
Flexible Grooved Coupling
Rigid Grooved Coupling
II. Kev ua haujlwm txawv
Qhov sib txawv ntawm kev ua haujlwm ntawm cov hlua khi thiab hloov tau yooj yim yog nyob rau hauv lawv lub peev xwm los hloov kho kom haum rau thermal expansion thiab contraction nyob rau hauv lub raj xa dej, hos cov couplings nruj tsis.
Grooved couplings yuav tsis zoo sib txawv ntawm ob hom no, tab sis lawv daim ntawv thov txawv. Flexible couplings tso cai rau axial hloov chaw thiab kev sib hloov hauv cov raj xa dej, yuam cov raj xa mus rau hauv lub xeev hloov tau, thaum cov couplings tsis muaj zog.
Cov kav dej uas siv cov couplings yog nruj; Hauv lwm lo lus, lub raj xa dej tsis tuaj yeem txav axially. Lawv tsis muaj cov yam ntxwv ntawm kev hloov pauv hloov pauv. Thaum cov yeeb nkab kawg txuas nrog, lawv tuaj yeem tsim ib chav tsev nrog cov yeeb nkab steel. Thaum qhov ntev ntawm cov khoom nqa nqa loj, cov kav dej tuaj yeem tso siab rau nws cov qauv nruj rau kev txhawb nqa. Hom kev sib txuas no feem ntau yog siv rau cov riser thiab cov kav dej sib txuas.
Flexible grooved couplings, thaum txuas nrog cov kav dej, tso cai rau ib nrab axial hloov chaw thiab kev sib hloov ntawm cov kav dej. Siv hom kev haum no tso cai rau lub kaw lus kom tswj tau yooj yim. Txawm tias muaj kev sib txuas ntawm cov yeeb nkab tsis zoo, qhov sib txawv ntawm ob lub kav dej, muab qhov chaw rau kev nthuav dav thiab kev cog lus. Lub coupling tswj ib txwm siab txawm nyob rau hauv siab tshaj plaws permissible misalignment.
III. Qhov sib txawv hauv Load Capacity
Flexible grooved couplings kuj tuaj yeem tiv taus qee qhov kawg loads. Hauv cov phiaj xwm sab hauv tsev, lub tsev, thiab cov kav khw hauv khw muag khoom, tsis muaj qhov sib txawv tseem ceeb hauv kev ua tau zoo ntawm kev sib txuas ua ke thiab hloov tau yooj yim. Txawm li cas los xij, nyob rau hauv cov dej num hauv av, hloov tau yooj yim couplings yog qhov zoo tshaj rau cov couplings nruj, muab qhov txiaj ntsig tseem ceeb. Cov kav dej hauv av tau raug rau ntau yam xws li kub thiab av noo, ua rau muaj teeb meem xws li thermal expansion thiab contraction, pipeline extension, deflection, thiab vibration. Flexible couplings tau yooj yim daws cov teeb meem no.
