Dab tsi yuav tsum tau txiav txim siab los tiv thaiv kev hnav ntawm lub raj xa dej?
Muaj ntau cov kav dej siv hauv pneumatic conveying system. Lub hauv paus ntsiab lus yog hais tias cov khoom yog circulated nyob rau hauv txhua lub raj xa dej nyob rau hauv lub thrust ntawm airflow thiab nws lub ntiajteb txawj nqus. Kev sib tsoo rov qab los ntawm cov khoom siv thiab cov kav dej yuav ua rau muaj kev cuam tshuam thiab hnav mus rau sab hauv phab ntsa ntawm cov kav dej, thiab cov kav dej yuav yooj yim hnav tawm thiab xau thaum lub sijhawm.
Nws yog ib qho tsim nyog los ua kom muaj kev hnav tsis kam ntawm cov kav dej. Hnav-resistant kav yuav tsum tau xaiv, xws li hnav-resistant ceramic puas kav, nws kuj hu ua hnav-resistant ceramic lined yeeb nkab luj tshib. Sab hauv phab ntsa ntawm cov yeeb nkab yog lined nrog alumina ceramics. Alumina ceramics muaj qhov hnav tsis zoo thiab tuaj yeem tiv taus qhov hnav thiab cuam tshuam ntawm cov khoom hauv cov yeeb nkab. Hnav-resistant ceramic composite yeeb nkab yog tsim nyog rau siv nyob rau hauv pneumatic conveying tshuab.
Lub luj tshib nyob rau hauv lub tshuab xa roj kuj tseem tuaj yeem hnav thiab tsim kua muag. Kev cuam tshuam thiab kev sib txhuam ntawm cov ntaub ntawv ntawm lub luj tshib yuav ua rau qhov nkhaus ntawm lub luj tshib tau yooj yim hnav los ntawm. Thaum lub kaum sab xis ntawm lub luj tshib yog ntau dua, nws yuav siv sij hawm ntev dua rau qhov ntws los ntawm lub luj tshib, thiab cov yeeb nkab yog ntau dua hnav thiab tsim kua muag. Yog li ntawd, lub vojvoog ntawm curvature ntawm lub luj tshib yuav tsum tau tsim kom tsawg li sai tau, thiab qhov chaw ntawm lub luj tshib uas nquag hnav yog lined nrog alumina ceramics nrog siab hnav tsis kam ua kom nws hnav tsis kam. Kev siv lub luj tshib-resistant ceramic tuaj yeem txhim kho lub neej kev pabcuam ntawm cov yeeb nkab, uas yog ntau tshaj kaum npaug ntawm lwm cov kav hlau.
