Mechanical Seal vs Gland Packing
Cov khoom siv foob thiab lub caj pas ntim khoom yog qhov tseem ceeb ntawm txhua lub twj tso kua mis thiab cov ncej thiab siv hauv ntau daim ntawv thov engineering. Ob hom kev foob yog siv feem ntau thiab nws nyob ntawm pob nyiaj siv, kev xav tau thiab kev xaiv ntawm tus kheej. Txawm li cas los xij, muaj qhov sib txawv ntawm cov yam ntxwv ntawm ob hom kev ntim khoom thiab ib qho yuav tsum ua tib zoo xaiv kom muaj tsawg tus nqi tu thiab tiv thaiv lwm yam snags uas feem ntau ntog nrog kev xaiv tsis raug. Cia peb ua qhov sib piv ceev ntawm cov tshuab foob thiab lub caj pas packing.
Rau qhov pib, lub caj pas ntim khoom, uas tseem hu ua cov pa roj hmab foob tsis yog feem ntau nyiam los ntawm cov kws tsim khoom vim qhov yuav tsum tau ua ntawm kev saib xyuas. Leakage yog qhov teeb meem tshaj plaws uas tshwm sim txhua lub sijhawm tam sim no. Nws yuav tsum tau kho kom muaj qhov tsim nyog lubrication ntawm lub foob. Tom qab ntawd muaj teeb meem ntawm corrosion vim yog cov kua abrasive. Qhov no feem ntau txo lub neej ua haujlwm ntawm lub foob ua rau ib qho siv rau ntawm lub foob tshiab. Txawm li cas los xij, muaj cov xwm txheej thaum lub caj pas ntim khoom yog qhov kev xaiv zoo tshaj plaws xws li thaum cuam tshuam nrog cov kua qaub. Lwm qhov tshwj xeeb hauv kev pom zoo ntawm cov qog nqaij hlav yog tias nyob rau hauv cov ntaub ntawv xau, nws tuaj yeem hloov kho kom lub twj tso kua mis nyob rau hauv qhov kev pab cuam vim qhov no tsis tuaj yeem ua rau lub tshuab foob raws li lub twj tso kua mis yuav tsum tau muab tshem tawm.
Mechanical seals yog li nrov dua hauv ntau daim ntawv thov. Lawv muaj ntau dua vim tias lawv muaj kev saib xyuas tsis pub dawb thiab cov neeg siv ntsib teeb meem tsawg heev. Lub neej expectancy ntawm ib tug neeg kho tshuab foob kuj yog nyob ntawm cov kua yog pumped, lub sij hawm ntawm kev ua hauj lwm thiab ua hauj lwm kub. Ob qho tib si cov ntsaws ruaj ruaj thiab lub caj pas ntim khoom yog nquag hnav thiab tsim kua muag vim lawv raug kev kub ntxhov thiab kub. Tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm mechanical seals, kev sib tsoo qhuav tuaj yeem ua rau kev puas tsuaj ntawm cov ntsaws ruaj ruaj.
Ib yam uas mus rau hauv kev pom zoo ntawm cov tshuab ntsaws ruaj ruaj yog lawv cov kev siv hluav taws xob tsawg. Vim tias muaj cov xau tsawg heev, tsis tshua muaj kev cuam tshuam thiab yog li kev txuag nyiaj uas tuaj yeem ua tau ntau lub sijhawm.
