Taw qhia
Polypropylene Random Copolymer (PPR) cov kav dej tau siv dav hauv ntau cov kav dej thiab HVAC (Tshav Kub, Qhov Cua, thiab Cua Txias) daim ntawv thov vim lawv cov khoom zoo xws li corrosion tsis kam, tshuaj inertness, thiab kav ntev. Txawm li cas los xij, ib qho kev sib tw uas tau ntsib los ntawm PPR cov kav dej yog tsim cov suab nrov thiab kev co thaum ua haujlwm. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov tswv yim thiab cov txheej txheem siv los tswj cov suab nrov thiab kev co hauv PPR cov kav dej.
Noise Generation Mechanisms
Lub hauv paus ntsiab lus ntawm lub suab nrov hauv PPR cov kav dej muaj xws li cov dej ntws, kev hloov pauv siab, thiab kev vibrations txhua yam. Turbulent ntws hauv cov kav dej tuaj yeem tsim suab nrov vim kev sib txhuam ntawm cov kua dej thiab cov yeeb nkab phab ntsa. Tsis tas li ntawd, kev hloov pauv sai sai, xws li qhov tshwm sim los ntawm lub qhov rooj qhib lossis kaw, tuaj yeem tsim cov dej rauj cuam tshuam ua rau lub suab nrov nrov. Cov tshuab vibrations los ntawm lub twj tso kua mis, lub cev muaj zog, lossis lwm yam khoom siv txuas nrog cov kav dej tuaj yeem ua rau muaj suab nrov tag nrho.
Noise Control Measures
Ob peb lub tswv yim tuaj yeem ua haujlwm los txo cov suab nrov hauv PPR cov kav dej. Thawj kauj ruam yog txhawm rau txo cov dej nrawm thiab qhov hloov pauv siab los ntawm cov kav dej kom zoo, li qub, thiab lwm yam khoom kom txo tau qhov kub ntxhov. Txhim kho cov pob qij txha los yog cov khoom sib txuas tau yooj yim tuaj yeem nqus cov dej siab thiab tiv thaiv dej rauj. Tsis tas li ntawd, cov ntaub ntawv rwb thaiv tsev acoustic xws li ua npuas ncauj lossis roj hmab tuaj yeem siv rau hauv cov kav dej kom tsis txhob muaj suab nrov. Kev sib cais cov khoom siv vibrating los ntawm cov kav dej siv cov khoom siv vibration isolators lossis mounting pads tuaj yeem pab txo cov suab nrov nrov.
Vibration Analysis thiab Damping
Kev ntsuam xyuas kev vibration yog qhov tseem ceeb rau kev txheeb xyuas cov hauv paus hauv paus ntawm cov tshuab kev co hauv PPR cov kav dej. Qhov no suav nrog kev ntsuam xyuas lub ntuj frequencies ntawm cov kav dej thiab cov khoom siv los txiav txim siab cov ntsiab lus muaj peev xwm resonance. Thaum pom tau tias, cov txheej txheem damping tuaj yeem siv los ua kom lub zog vibration thiab txo cov suab nrov. Cov txheej txheem damping feem ntau suav nrog kev siv cov khoom siv vibration-absorbing xws li elastomeric pads lossis isolators, nrog rau kev hloov kho cov qauv kom khov lossis dampen vibrating Cheebtsam.
Installation Cov kev coj ua zoo tshaj plaws
Cov txheej txheem kev teeb tsa kom raug yog qhov tseem ceeb rau kev txo qis suab nrov thiab kev co hauv PPR cov kav dej. Kev saib xyuas yuav tsum tau ua kom ruaj ntseg rau cov kav dej, cov li qub, thiab cov fittings kom tiv thaiv kev txav los yog kev co. Kev txhawb nqa yooj yim lossis cov hangers tuaj yeem siv los nqus cov kev poob siab thiab kev vibrations. Tsis tas li ntawd, zam kev khoov ntse thiab kev cuam tshuam hauv cov txheej txheem piping tuaj yeem pab tswj cov kua dej ntws zoo thiab txo cov suab nrov nrov.
Kev saib xyuas thiab kev tu tsis tu ncua
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua yog qhov tseem ceeb rau kev ua kom lub sijhawm ntev ntawm cov suab nrov thiab kev co tswj kev ntsuas hauv PPR cov kav dej. Kev soj ntsuam cov cuab yeej ua tau zoo, tshawb xyuas cov cim ntawm kev hnav lossis kev puas tsuaj, thiab daws txhua yam teeb meem tam sim ntawd tuaj yeem pab tiv thaiv cov teeb meem suab nrov thiab kev vibration los ntawm kev nce ntxiv. Tsis tas li ntawd, kev ntsuas kev vibration ib ntus thiab kev soj ntsuam tuaj yeem txheeb xyuas cov teeb meem tshwm sim ua ntej lawv ua rau lub cev tsis ua haujlwm lossis poob sijhawm.
Xaus
Kev tswj lub suab nrov thiab kev vibration hauv PPR cov kav dej yog qhov tseem ceeb rau kev tswj xyuas qhov chaw xis nyob thiab ua haujlwm zoo hauv thaj chaw nyob, kev lag luam, thiab kev lag luam. Los ntawm kev nkag siab txog cov txheej txheem ntawm kev tsim suab nrov, ua raws li kev tswj xyuas kom tsim nyog, thiab ua raws li cov kev coj ua zoo tshaj plaws rau kev teeb tsa thiab kev saib xyuas, engineers thiab cov neeg saib xyuas chaw tuaj yeem txo cov suab nrov thiab kev vibration teeb meem, kom ntseeg tau tias muaj kev ntseeg siab thiab nyob ntsiag to ntawm PPR yeeb nkab tshuab rau xyoo tom ntej.
