Tus qauv tsim yuav tsum xyuas kom meej tias lub kaw lus ua haujlwm nyob rau hauv qhov kev ceev siab tshaj plaws uas tau teev tseg thaum suav nrog cov xwm txheej muaj peev xwm overspeed.
④ Cov teebmeem thermal:
Tus tsim yuav tsum suav rau thermal expansion thiab contraction, ua kom muaj kev ua haujlwm zoo thoob plaws tag nrho qhov ntsuas kub.
API 671 Coupling Khoom specifications
① High-Strength Steels:
Hom Qib:API txuasfeem ntau siv cov hlau alloys muaj zog xws li AISI 4140, 4340, lossis cov ntaub ntawv zoo sib xws.
Cov Khoom Siv: Cov hlau no paub txog lawv lub zog zoo heev, toughness, thiab qaug zog tiv thaiv, ua rau lawv tsim nyog rau kev siv siab.
②Stainless hlau:
Cov Qib Siab: Cov qib stainless hlau zoo li AISI 316, 321, thiab 347 qee zaus siv rau lawv cov kev tiv thaiv corrosion.
Cov yam ntxwv ntawm cov hlau tsis muaj steel yog qhov tsim nyog rau lawv cov kev tiv thaiv corrosion thiab oxidation, uas yog ib qho tseem ceeb nyob rau hauv ib puag ncig hnyav.
③Nickel-Based Alloys:
Cov Qib: Inconel (xws li Inconel 718) thiab lwm yam nickel-raws li alloys yuav siv tau rau cov ntawv thov uas yuav tsum tau kub-kub lub zog thiab zoo heev corrosion kuj.
Cov Khoom: Cov alloys no muab kev tiv thaiv zoo rau kev kub siab oxidation thiab tswj lawv cov khoom siv kho mob nyob rau hauv huab cua.
④ Titanium Alloys:
Kev siv Titanium alloys xws li Ti-6Al-4V hauv cov ntawv thov tshwj xeeb uas qhov sib piv ntawm lub zog-rau-qhov hnyav thiab kev tiv thaiv corrosion yog qhov tseem ceeb yog hu ua Common Grades.
Cov khoom ntawm titanium suav nrog nws lub teeb yuag, muaj zog, thiab tiv taus corrosion, ua rau nws tsim nyog rau kev ua haujlwm siab.
API 671 Coupling Test Procedures
API txuasKev ntsuas kev sib npaug yog ib txoj hauv kev tseem ceeb los xyuas kom meej tias cov couplings siv nyob rau hauv rotating machinery ua haujlwm zoo thiab ntseeg tau. Cov couplings tsis sib npaug tuaj yeem ua rau muaj kev vibration ntau dhau, ua rau hnyav dua, thiab muaj peev xwm ua tsis tau ntawm cov tshuab.
① Txo kev vibrations: Kev sib txuas kom zoo yuav pab txo qis kev vibrations, uas tuaj yeem ua rau kev puas tsuaj thiab txo lub neej ntawm lub tshuab.
② Txhim kho Efficiency: Sib npaug couplings kom muaj zog sib kis tau zoo thiab txo qis zog.
③ Txhim kho kev nyab xeeb: txo qis kev vibrations thiab tiv thaiv kev tsis sib haum xeeb cuam tshuam txog kev ua haujlwm ntawm kev ruaj ntseg ntawm lub tshuab.
④ Ua raws: Ntau cov qauv kev lag luam, suav nrog API 671, yuav tsum muaj kev sib txuas ua ke kom sib npaug rau cov kev zam tshwj xeeb.
◆ Overspeed Test:
Kev ntsuas overspeed yog ib feem tseem ceeb ntawm cov txheej txheem validation rau couplings siv nyob rau hauv high-ceev rotating machinery. Qhov kev sim no ua kom ntseeg tau tias qhov sib txuas tuaj yeem tiv taus qhov nrawm dua li nws qhov kev ua haujlwm siab tshaj plaws yam tsis ua haujlwm.
Lub hom phiaj ntawm Kev Tshawb Fawb Tshaj Tawm
① Txheeb xyuas cov qauv kev ncaj ncees: txhawm rau xyuas kom lub coupling tuaj yeem ua haujlwm dhau sijhawm dhau sijhawm yam tsis muaj kev ua haujlwm tsis ua haujlwm.
②Safety Assurance: Kom paub meej tias qhov sib txuas yuav tsis tawg lossis ua haujlwm tsis zoo yog tias nws ntsib kev nrawm dua li qhov kev txwv.
③ Kev Ua Raws Cai: Ua kom tau raws li cov qauv kev lag luam thiab cov kev qhia tshwj xeeb, xws li cov txheej txheem API 671, uas yuav xav tau kev ntsuas nrawm dhau los ua ib feem ntawm cov txheej txheem tsim nyog.
