Thaum lub sij hawm tsis muaj-load sim ua haujlwm ntawm asphalt tov khoom, lub tshuab dheev poob, thiab qhov teeb meem ntawm kev pib dua tseem muaj. Qhov no tuaj yeem ua rau cov neeg siv ntxhov siab, thiab cov txheej txheem ua haujlwm yuav raug ncua. Qhov teeb meem yuav tsum tau kov yeej sai li sai tau.

Hauv qhov no, tib txoj kev xaiv yog sim hloov cov thermal relay ntawm asphalt tov khoom nrog ib qho tshiab, tab sis qhov teeb meem tseem tsis tau daws; thiab cov contactor, lub cev muaj zog theem tsis kam, grounding kuj, theem voltage, thiab lwm yam yog kuaj, tab sis tsis muaj teeb meem; tshem nws Txoj siv kis tau tus mob thiab pib vibrating npo yog txhua yam qub, uas qhia tau hais tias qhov txhaum ntawm asphalt tov khoom tsis yog nyob rau hauv hluav taws xob.
Kuv tsuas tuaj yeem rov txhim kho txoj siv kis tau tus mob thiab rov pib lub vibrating npo, tsuas yog kom pom tias qhov thaiv eccentric tau ntaus hnyav dua. Tom qab hloov lub vibrating npo bearing, txhim kho lub eccentric thaiv, thiab rov pib lub vibrating screen, lub ammeter qhia tau zoo li qub thiab lub tshuab lub tripping tshwm sim ploj.
