Qhov kawg ntawm cov yeeb nkab yog li no a qhov chaw txav chaw. Txhawm rau kom tsis txhob txav huab cua, kaw cov yeeb nkab kawg yuav tsum tau siv lub zog ntawm cov molecules los ntawm kev siv lub siab, kom qhov kawg kaw yog lub siab antinode.
Puas yog cov yeeb nkab kaw ntawm ib kawg lossis nws qhib rau ob qhov kawg?
Kev sib txuas ntawm tag nrho cov cuab yeej no yog qhov ntev ntawm lub raj txiav txim siab lub suab ntawm cov yeeb nkab ua. … Nco ntsoov tias cov kav dej tuaj yeem muaj ob qhov kawg qhib, lossis muaj ib qho kawg qhib thiab ib kawg kaw. Rau lub suab nthwv dej, qhov qhib kawg ntawm cov yeeb nkab zoo li qhov kawg pub dawb, thaum lub kaw qhov kawg ntawm cov yeeb nkab zoo li qhov kawg.
Thaum ib kawg ntawm cov yeeb nkab kaw?
Ib lub yeeb nkab kaw yog ib qho uas ib qho kawg qhib thiab lwm qhov raug kaw, thiab zoo li cov kav dej qhib, cov no tuaj yeem tsim nthwv dej nrog lub suab ntawm qhov tsim nyog.
Vim li cas thiaj muaj qhov kawg ntawm cov kav dej kaw?
kaw cov raj Cov huab cua molecules tsis muaj kev vibration rov qab thiab tawm mus rau tib lub raj, yog li
qhov kev hloov chaw sawv nthwv dej muaj yogib qho ntawm qhov kaw kawg. Qhov qhib kawg ntawm lub raj yog ib txwm muaj antinode txij li cov huab cua molecules tuaj yeem vibrate horizontally parallel mus rau qhov ntev ntawm lub raj.
Vim li cas thiaj tsis muaj qhov sib haum xeeb hauv cov yeeb nkab uas raug kaw ntawm ib kawg?
Closed Cylinder Air Column
Qhov kawg kaw yog txwv los ua ib qho ntawm nthwv dej thiab qhov qhib kawg yog qhov tseeb antinode. Qhov no ua rau lub hom phiaj tseem ceeb xws li lub wavelength yog plaub npaug ntawm qhov ntev ntawm huab cua. Qhov kev txwv ntawm qhov kawg kaw tiv thaiv kablos ntawm kev tsim cov kev sib raug zoo.
Pom zoo:
Puas yog qhov kub thiab txias cuam tshuam qhov zaus ntawm cov yeeb nkab hauv nruab nrog cev?
Qhov cuam tshuam ntawm cua sov ntawm cov yeeb nkab zaus ntau dua li qhov nce ntawm qhov ntev ntawm cov yeeb nkab kom qhov zaus ntawm cov yeeb nkab hauv nruab nrog cev nce ntxiv thaum kub nce. Thaum kub nce zaus ntawm cov yeeb nkab hauv nruab nrog cev?
Nyob rau lub sijhawm 80 yeeb nkab?
Teem sijhawm 80 PVC yeeb nkab yog siv rau kev lag luam thiab kev siv dej siab dua. Teem sijhawm 80 PVC yeeb nkab tuaj yeem tuav 140 degrees F hauv qhov kub thiab txias. Cov yeeb nkab tuaj hauv cov qauv 10' lossis 20' ntu thiab muaj nyob rau hauv qhov kawg lossis lub tswb kawg yog li tsis muaj kev sib txuas yog xav tau rau kev teeb tsa.
Vim li cas cov yeeb nkab flanges siv?
Flanges yog siv txhawm rau txuas li qub, kav dej, twj thiab lwm yam khoom siv los ua cov kav dej. Feem ntau flanges yog welded los yog threaded, thiab ob lub flanges txuas ua ke los ntawm bolting lawv nrog gaskets muab lub foob uas muab kev yooj yim nkag mus rau hauv cov kav dej.
Vim li cas qhov ntev ntawm cov yeeb nkab cuam tshuam rau lub suab?
Lub ntev lub raj yog qhov qis dua ntawm daim ntawv uas nws tuaj yeem tso tawm. Thaum lub raj cua sov nws nthuav dav thiab ntev dua! Yog li, yog tias qhov kub ntawm lub raj mus rau qhov ntev yuav luv dua thiab lub suab ntawm daim ntawv yuav tsum tau siab dua.
Cov yeeb nkab condensate nyob qhov twg ntawm boiler?
Saib hauv qab lub boiler kom pom tias muaj cov yeeb nkab yas - Nws feem ntau yog dawb thiab nyob ib ncig ntawm 20mm (txog ¾ ") dav. Cov yeeb nkab yuav tsum khiav mus rau sab nraud ntawm koj lub tsev thiab yuav tsum khiav mus rau hauv qhov dej ntws.
