Ndi chitukuko chofulumira cha mayendedwe apanyanja komanso kusinthanitsa pafupipafupi kwamayiko akunja, chuma chafalikira padziko lonse lapansi, ndipo makampani opanga makina a asphalt nawonso. Zida zochulukirachulukira za phula zimatumizidwa kunja. Komabe, popeza malo ogwiritsira ntchito zida za asphalt kunja ndi kosiyana ndi komwe ku China, makampani apakhomo amayenera kulabadira zovuta zina akamapanga zida za phula. Ndi nkhani ziti zomwe ziyenera kutsatiridwa ndi ife omwe takhala ndi zaka zambiri za kukonza, kupanga ndi kutumiza kunja zida za asphalt.
Choyamba, pali zovuta zingapo zomwe zimayambitsidwa ndi magetsi osiyanasiyana:

1. Mphamvu zamagetsi m'mayiko ambiri ndizosiyana ndi zathu. Zoweta mafakitale gawo voteji ndi 380V, koma ndi osiyana kunja. Mwachitsanzo, mayiko ena ku South America amagwiritsa ntchito 440v kapena 460v, ndipo maiko ena ku Southeast Asia amagwiritsa ntchito 415v. Chifukwa cha kusiyana kwa magetsi, tiyenera kusankhanso zida zamagetsi, ma motors, ndi zina.
2. Mphamvu pafupipafupi ndi yosiyana. Pali miyeso iwiri yama frequency amagetsi padziko lapansi, dziko langa ndi 50HZ, ndipo mayiko ambiri ndi 60hz. Kusiyanasiyana kwafupipafupi kungayambitse kusiyana kwa liwiro la injini, kukwera kwa kutentha, ndi torque. Izi ziyenera kuganiziridwa panthawi yopanga ndi kupanga. Nthawi zambiri tsatanetsatane imatsimikizira ngati zidazo zitha kugwira ntchito bwino kudziko lachilendo.
3. Pamene liwiro la galimoto likusintha, kuthamanga kwa pampu yofanana ya asphalt ndi emulsion pump idzawonjezeka moyenerera. Momwe mungasankhire mitayo yoyenera ya chitoliro, kuchuluka kwakuyenda kwachuma, ndi zina zambiri. Iyenera kuwerengedwanso motengera equation ya Bernoulli.
Kachiwiri, pali mavuto obwera chifukwa cha nyengo zosiyanasiyana. Ambiri a dziko langa ali m'dera lotentha ndipo ndi la nyengo yotentha ya monsoon. Kupatula zigawo zingapo payekha, magetsi apanyumba, injini zamagalimoto, dizilo, ndi zina zotere zidaganiziridwa pamiyezo yopangidwira panthawiyo. Onse zoweta emulsion phula zida ali ndi zabwino zoweta kusinthika. Emulsion phula zida zimagulitsidwa ku mayiko akunja akhoza acclimatized chifukwa cha nyengo. Zifukwa zazikulu ndi izi:
1. Chinyezi. Mayiko ena ndi otentha komanso amvula komanso amagwa mvula, zomwe zimapangitsa kuti pakhale chinyezi chachikulu, chomwe chimakhudza kutsekemera kwa zipangizo zamagetsi. Zida zoyamba za emulsion phula zomwe tidatumiza ku Vietnam zinali zovuta kugwira ntchito chifukwa cha izi. Pambuyo pake, maiko oterowo anasintha.
2. Kutentha. Chida cha emulsion cha phula palokha ndi chida chomwe chimafuna kutentha kuti chigwire ntchito. Malo ogwirira ntchito ndi okwera kwambiri. Ngati imagwiritsidwa ntchito m'nyumba, patatha zaka zambiri, sipadzakhala vuto ndi kasinthidwe ka gawo lililonse. Emulsified asphalt sangathe kugwira ntchito m'malo otentha (pansi pa 0 ° C), kotero sitidzakambirana za kutentha kochepa. Kutentha kwa injini chifukwa cha kutentha kwakukulu kumakhala kokulirapo, ndipo kutentha kwa mkati kumakwera kuposa mtengo wopangidwa. Izi zipangitsa kulephera kwa insulation ndikulephera kugwira ntchito. Choncho, kutentha kwa dziko lotumiza kunja kuyeneranso kuganiziridwa.
