Chifukwa chakukula kwachangu kwa misewu yayikulu komanso kufunikira kwa phula, phula lokhala ndi mipiringidzo lakhala likugwiritsidwa ntchito kwambiri chifukwa cha mayendedwe ake mtunda wautali komanso malo abwino osungira. Makamaka, phula zambiri zomwe zimatumizidwa kunja zomwe zimagwiritsidwa ntchito m'misewu yothamanga kwambiri zimakhala ndi mipiringidzo. Izi Chomera chosungunula phula chomwe chimasungunuka msanga, chimachotsa migolo mwaukhondo, ndikuletsa phula kukalamba chimafunika.

Zida zopangira phula zomwe zimapangidwa ndi kampani yathu makamaka zimakhala ndi bokosi lochotsa mbiya, chitseko chokweza magetsi, thirayi yonyamula phula, trolley drive system, makina otenthetsera mafuta, makina otenthetsera mafuta otenthetsera mpweya, pampu ya phula ndi mapaipi, ndi magetsi. dongosolo control ndi mbali zina.

Bokosilo limagawidwa m'zipinda zapamwamba ndi zapansi. M’chipinda cham’mwambamo muli chipinda chotulutsira mbiya ndi kusungunula phula. Chitoliro chotenthetsera mafuta m'munsi ndi mpweya wotentha kwambiri wochokera mu boiler yamafuta otenthetsera molumikizana kutenthetsa migolo ya phula kuti mukwaniritse cholinga chochotsa phula. Chipinda chapansi chimagwiritsidwa ntchito makamaka kupitiriza kutentha phula lotengedwa mumgolo. Kutentha kukafika pakutentha (pamwamba pa 110 ° C), mpope wa asphalt ukhoza kuyamba kutulutsa phula. M'mapaipi a phula, fyuluta imayikidwa kuti ichotse zotsalira za slag mu phula lokhala ndi mipiringidzo.

Zida zopangira phula zosungunula phula zili ndi malo ogawa mozungulira zidebe zozungulira kuti chidebe chilichonse chiziyika bwino potsegula. Njira yopatsirana ndi yomwe imayang'anira kukweza ndi kutsitsa migolo yolemera yodzaza ndi phula ndi migolo yopanda kanthu mutatsuka ndikutuluka m'chipinda chapamwamba cha bokosilo. Njira yogwirira ntchito ya zidazo imamalizidwa ndi ntchito yapakati mu kabati yowongolera magetsi, ndipo imakhala ndi zida zowunikira komanso zida zowongolera chitetezo.
