Lub tshuab ntxhua khaub ncaws yog cov khoom siv los yog cov khoom sib xyaw ua ke ntawm cov khoom sib txuas ntawm ob qhov kev sib txuas ywj pheej (feem ntau yog flanges), uas nws txoj haujlwm yog los tuav lub foob ntawm ob qhov txuas thaum lub sijhawm ua haujlwm tau teem tseg.Lub tshuab ntxhua khaub ncaws yuav tsum muaj peev xwm kaw qhov sib koom ua ke thiab xyuas kom meej tias cov sealing nruab nrab yog impermeable thiab tsis corroded, thiab tuaj yeem tiv taus qhov kub thiab txias.Cov ntxhua khaub ncaws feem ntau muaj cov connectors (xws li flanges), washers, thiab fasteners (xws liboltsthiabtxiv ntseej ) . Yog li ntawd, thaum txiav txim siab qhov kev sib khi ntawm ib qho flange, tag nrho cov flange kev twb kev txuas yuav tsum raug suav hais tias yog ib qho system. Kev ua haujlwm ib txwm lossis tsis ua haujlwm ntawm lub tshuab ntxhua khaub ncaws tsis yog tsuas yog nyob ntawm kev ua haujlwm ntawm lub tshuab ntxhua khaub ncaws tsim nws tus kheej, tab sis kuj yog nyob ntawm qhov nruj thiab deformation ntawm lub cev, qhov roughness thiab parallelism ntawm qhov sib koom ua ke, thiab qhov loj thiab qhov sib xws ntawm qhov ceev ceev.
Tsib lub ntsiab ntawm Shim Xaiv:
1. kub:
Ntxiv rau qhov siab tshaj plaws thiab qhov ntsuas kub ua haujlwm tsawg kawg nkaus uas tuaj yeem zam tau rau lub sijhawm luv luv, qhov kev tso cai ua haujlwm tsis tu ncua yuav tsum tau txiav txim siab. Cov khoom siv ntxhua khaub ncaws yuav tsum muaj peev xwm tiv taus creep kom txo tau kev ntxhov siab ntawm lub tshuab ntxhua khaub ncaws, txhawm rau kom ntseeg tau tias nws sealing hauv kev ua haujlwm. Cov ntaub ntawv ntxhua khaub ncaws feem ntau yuav muaj kev nkag siab hnyav thaum qhov kub nce. Yog li ntawd, qhov taw qhia tseem ceeb ntawm lub tshuab ntxhua khaub ncaws zoo yog qhov ua tau zoo ntawm lub tshuab ntxhua khaub ncaws ntawm qhov kub thiab txias.
2.application:
Nws tsuas yog hais txog cov ntaub ntawv ntawm kev sib txuas ntawm qhov chaw ntxhua khaub ncaws, thiab cov khoom siv ntxhua khaub ncaws tsim nyog thiab hom yuav tsum tau xaiv raws li cov khoom siv ntawm flange, sealing nto hom ntawm flange, roughness ntawm lub flange. flange , thiab cov ntaub ntawv bolt. Cov flanges uas tsis yog xim hlau yuav tsum xaiv cov gaskets uas yuav tsum tau ua ntej nruj nruj, txwv tsis pub tej zaum yuav muaj cov xwm txheej uas lub gasket tsis tau compressed tsis tau thiab cov flange tau crushed thaum lub sij hawm flange zawm txheej txheem.
3. nruab nrab:
Lub tshuab ntxhua khaub ncaws yuav tsum tsis muaj kev cuam tshuam los ntawm qhov nruab nrab sealing thoob plaws hauv kev ua haujlwm, suav nrog kev kub siab oxidation tsis kam, tshuaj lom neeg corrosion, hnyav tsis kam, permeability tsis kam, thiab lwm yam. rau xaiv lub tshuab ntxhua khaub ncaws.
4. siab:
Lub tshuab ntxhua khaub ncaws yuav tsum muaj peev xwm tiv taus qhov siab tshaj plaws, uas tej zaum yuav yog qhov kev sim siab, uas tej zaum yuav yog 1.25 mus rau 1.5 npaug ntawm kev ua haujlwm siab. Rau cov khoom siv tsis yog xim hlau, lawv qhov siab tshaj plaws kuj tseem cuam tshuam rau qhov siab tshaj plaws ua haujlwm kub. Feem ntau, tus nqi ntawm qhov kub siab tshaj qhov sib npaug ntawm qhov siab tshaj plaws (piv txwv li PxT tus nqi) muaj qhov txwv tus nqi. Yog li ntawd, thaum xaiv lawv qhov siab tshaj plaws ua haujlwm siab, nws tseem yuav tsum tau xav txog qhov siab tshaj plaws PxT tus nqi uas lub gasket tuaj yeem tiv taus.
5.size:
Rau feem ntau tsis yog-metallic ntawv washers , nyias washers kuj muaj peev xwm ntau dua los tiv thaiv kev ntxhov siab. Vim qhov chaw me me ntawm kev sib cuag ntawm sab hauv ntawm lub tshuab ntxhua khaub ncaws nyias thiab qhov nruab nrab, qhov to ntawm lub tshuab ntxhua khaub ncaws kuj raug txo, thiab nyob rau hauv rooj plaub no, lub tshuab nqus tsev los ntawm lub tshuab ntxhua khaub ncaws kuj yog me me, ua rau nws nyuaj rau lub tshuab ntxhua khaub ncaws. tshuab ntxhua khaub ncaws
