Thaum lub sij hawm tsis muaj-thauj mus sib hais ua haujlwm ntawm asphalt tov, lub tshuab tam sim ntawd tripped, thiab qhov teeb meem ntawm kev pib dua tseem muaj. Qhov no tuaj yeem ua rau cov neeg siv kev ntxhov siab, thiab cov txheej txheem ua haujlwm yuav qeeb. Qhov teeb meem yuav tsum tau kov yeej sai li sai tau.

Hauv qhov no, tsuas yog kev xaiv yog sim hloov cov thermal relay ntawm asphalt tov nrog ib qho tshiab, tab sis qhov teeb meem tseem tsis tau daws; Thiab tus neeg sib cuag, lub cev muaj zog ua hauj, theem tsis kam, theem voltage, thiab lwm yam raug kuaj xyuas; Tshem nws cov kev xa tawm thiab pib vibrating npo yog txhua qhov qub, uas qhia tau hais tias kev txhaum ntawm asphalt tov tsis nyob hauv cov hluav taws xob.
Kuv tsuas yog rov nruab txoj siv sia thiab rov qab pib lub vijtsam vibrating, tsuas yog kom pom tias cov eccentric block tau ntaus ntau dua li kev ntaus heev. Tom qab hloov lub vibrating npo coj cov kabmob, txhim kho ECCENTRIC thaiv, thiab rov ua dua lub vibrating pib thiab lub tshuab tripping tshwm sim.
