Tus npauj npaim lub taub hau yog ib hom taub hau nyob rau hauv cov cuab yeej siab txog nkoj, muaj npe rau nws cov duab geometric. Piv nrog rau lwm hom taub hau, npauj npaim lub taub hau hluav taws xob ntau ntau yam ntxwv ntawm cov qauv tsim qauv thiab cov ntaub ntawv thov. Kab lus no yuav qhia txog cov yam ntxwv thiab qhov zoo ntawm tus qauv npauj npaim ntawm nws cov qauv pib, cov khoom siv cov khoom siv, muaj cov xwm txheej siv tau, thiab kev lag luam.
1. Cov Qauv Txheej Txheem
Tus npauj npaim taub hau muaj peb ntu: ib ntu spherical, lub nplhaib hloov pauv, thiab ntu ncaj. Lub spherical tshooj yog lub ntsiab}}} bearing} cov kabmob thaj tsam ntawm curvature feem ntau tuaj yeem ua kom zoo tawg sab hauv siab. Lub nplhaib Transition plhaub txuas cov spherical seem thiab ntu ncaj qha, txo kev hloov pauv kev ntxhov siab los ntawm kev hloov pauv kev hloov pauv. Ntu ntug kev ncaj yog siv rau taub qab vuam rau lub nkoj txiav txim siab. Qhov kev ua ke sib xyaw ua ke ua kom muaj kev ntxhov siab ntawm lub taub hau thaum tsis txhob muaj kev ntxhov siab hauv ib puag ncig hauv nroog los ntawm kev hloov pauv ntau hauv nroog.
2. Cov Khoom Siv Ntau Yam
Npauj npaim taub hau tuaj yeem siv cov ntaub ntawv sib txawv raws li cov ntawv thov. Cov ntaub ntawv nquag muaj xws li cov hlau, hlau hlau, hlau hlau, thiab cov hlau alloy. Carbon Steel Hau yog cov pheej yig thiab haum rau ib puag ncig muaj kev lag luam; stainless hlau taub hau muaj zoo corrosion tsis kam thiab yog siv ntau siv hauv kev lag luam tshuaj thiab zaub mov; alloy steel heads are mostly used in high-temperature and high-pressure environments. Cov kev xaiv ntawm cov khoom cuam tshuam rau kev pabcuam lub neej thiab kev nyab xeeb ntawm lub taub hau, yog li ntawd, nws yog qhov tsim nyog los xaiv cov hom uas tsim nyog raws cov kev ua haujlwm tshwj xeeb.
3. Kev Ua Haujlwm Zoo
Nyob rau hauv lub siab sab hauv, kev ntxhov siab faib ntawm lub taub hau npauj npaim yog cov khoom siv hluav taws xob. Vim nws txoj kev nkhaus du hauv qhov chaw hloov pauv, nws zam qhov kev ntxhov siab siab concentration teeb meem ntawm cov npoo ntawm lub taub hau tiaj tus taub hau. Piv nrog hemispherical hau, lub taub hau npauj npaim yog qhov tsis zoo, txo qhov chaw siab tshaj plaws thiab txuag cov khoom siv txuag. Npauj npaim taub hau ua rau muaj kev qaug zog zoo dua hauv kev ua haujlwm zoo ib yam nkaus rau cov ntawv thov kom nquag siv lossis ua haujlwm siab lossis loj.
4. Kev tsim khoom thiab ua kom yooj yim
Cov txheej txheem tsim khoom lag luam rau npauj npaim lub taub hau yog tus ua kom paub tab, thiab feem ntau cov tuam ntxhab tuaj yeem ua tiav cov txheej txheem txias, kub stamping, lossis kiv. Vim yog lub siab mos curvature hloov pauv hauv thaj chaw hloov pauv, pwm hnav yog tsawg, uas tau txais txiaj ntsig zoo rau huab hwm coj ntau lawm. Hais txog vuam, ncaj- ntug tsim ua rau lub taub hau wandd nruab nrab ntawm lub taub hau thiab kev tshuaj xyuas teeb meem thiab kev phom sij zoo.
