Grooved couplings yog ib qho tseem ceeb ntawm cov yeeb nkab txuas txuas; Lawv cov yam ntxwv tseem ceeb yog raws li nram no:
Kev sib xyaw ua ke
Lawv feem ntau muaj peb yam: roj hmab sealing gasket, coupling vaj tse, thiab locking bolts. Qee cov qauv muaj cov qauv tsim tshwj xeeb- xws li cov qauv nruj lossis hloov tau yooj yim- kom haum raws li cov kev xav tau ntawm kev ua haujlwm sib txawv.
Cov yam ntxwv ua haujlwm
Kev txhim kho yog yooj yim thiab yuav tsum tsis muaj vuam lossis txoj kev txawj tshwj xeeb; Cov neeg ua haujlwm zoo tib yam tuaj yeem ua txoj haujlwm tom qab kev cob qhia luv luv, thiab kev teeb tsa kev nrawm nrawm dua li cov kev sib txuas ib txwm muaj.
Sealing kev ua tau zoo txhim kho nyob rau hauv tandem nrog nce siab hauv cov kua; Qhov ntsuas siab nce mus txog 2.5 MPa, haum rau cov yeeb nkab loj xws li DN20 txog DN600.
Lawv tsis ua puas tsuaj rau sab hauv los tiv thaiv -corrosion txheej ntawm cov yeeb nkab, tso cai rau kev sib txuas tsis zoo los yog hloov tau yooj yim, thiab tuaj yeem them nyiaj rau kev hloov pauv los ntawm thermal expansion thiab contraction.
Kev siv dav dav
Lawv tsim nyog rau ntau lub tshuab-xws li kev tiv thaiv hluav taws, dej thiab dej ntws, thiab petrochemicals- thiab yog sib xws nrog ntau hom piping cov ntaub ntawv xws li carbon steel, stainless hlau, thiab yas-liab steel. Lawv txhawb nqa ob qho tib si raug thiab faus kev teeb tsa.
