Asphalt Paver Screed hauv qab phaj sib dhos nrog rau cov cua sov Rods Screed Phaj thiab Tamper Bars
Lub screed hauv qab phaj, nrog rau lub ntsiab screed phaj sib dhos, ua rau lub screed phaj sib dhos ntawm ib qho asphalt paver.Lub screed hauv qab phaj txuas mus rau hauv qab ntawm lub ntsiab screed phaj thiab ua ke lawv pab theem, du, thiab compact asphalt khoom thaum nws tawm hauv paver.Txuas rau hauv qab phaj yog cov khoom tseem ceeb, nrog rau cov cua sov, tamper bar, thiab siab bar.Lub hom phiaj tseem ceeb ntawm screed hauv qab phaj yog kom ruaj ntseg txhua qhov yuav tsum tau ua kom zoo compaction thiab smoothing ntawm asphalt khoom.Lub phaj steel muab cov khoom ruaj khov, ruaj khov uas tuaj yeem tiv taus qhov kub thiab txias.Cov cua sov rods txuas ncaj qha mus rau hauv qab ntawm cov hlau phaj kom sov cov screed daim hlau mus rau qhov xav tau paving kub.Lub tamper bar yog steel bar uas mounted rau hauv qab heev ntawm screed hauv qab phaj.Nws ua hauj lwm kom ntxiv compact thiab du cov ntaub ntawv asphalt thaum nws hla hauv qab screed.Lub siab bar nrog cov hydraulic pulsing system ua rau muaj kev sib zog ua haujlwm siab ntawm cov pavement hauv paving, thiab nws yuav tsum tiv taus kev ntxhov siab loj thaum lub sijhawm ua haujlwm.
Cov khoom siv tes ua asphalt paver screed hauv qab phaj sib dhos tuaj yeem ua tau zoo rau yuav luag txhua hom nrov asphalt pavers, xws li VOGELE, DYNAPAC, CAT thiab lwm yam. Cov khoom txuas nrog rau cov screed hauv qab phaj ua hauj lwm ua ke kom zoo sib kis, compact, thiab kev ntxhib los mos cov ntaub ntawv asphalt. .Cov rhuab screed daim hlau sov lub asphalt mus rau qhov kub thiab txias rau kev ua haujlwm.Cov vibrators ceev ceev cov khoom siv hauv qab screed.Thaum kawg, lub tamping bar muab qhov pib nto kev ntxhib los mos thiab compaction raws li lub asphalt tawm ntawm hauv qab lub screed.Los ntawm kev txuas ntau yam uas yuav tsum tau ua rau paving rau lub phaj hauv qab, lub phaj pab ua kom lub screed sib dhos ua tiav nws txoj haujlwm.Lub phaj hauv qab, nrog rau lub ntsiab screed phaj, ua rau lub plawv ntawm lub screed system.Nws cov Cheebtsam ua haujlwm ua ke kom ua tiav qhov tseem ceeb paving qhov yuav tsum tau ua ntawm longitudinal joint compaction, deg smoothness, pavement depth control, and deg texture asphalt material flows under the haib screed phaj sib dhos thaum lub sijhawm ua haujlwm paving.
