pobowola makina ozungulira

Pali mitundu iwiri: imodzi ili mu makina obowola mozungulira potengera kuwonjezera mphamvu, makamaka pobowola mozungulira, pokumana ndi mwala wosanjikiza wobowola pawiri-cholinga chobowola bwino, kusinthasintha kwamphamvu kumagulu osiyanasiyana;Zina ndi momwe zimagwirira ntchito komanso zozungulira zomwe zimaphatikizidwa ndi chobowolera chitsime, monga kubowola nyundo ya DTH.Kubowola nyundo ya DTH (FIG. 5) kumapangidwa ndi cylinder liner ndi pistoni yomwe imayenda mmwamba ndi pansi muzitsulo za silinda.Mapeto apansi a cylinder liner amalumikizidwa ndi kubowola, ndipo kumtunda kumalumikizidwa ndi chitoliro chobowola kudzera pagulu lolumikizidwa.Mpweya wothamanga kwambiri woperekedwa ndi mpweya wa compressor ndi 0.7 ~ 1.4 mpa kupyolera mu valavu yoyang'ana pamwamba pa pisitoni, wogawira mpweya ndi mpweya wolowera pansi pa pistoni, ndipo mafupipafupi a pistoni amakankhidwira mmwamba ndi pansi ngati 700 ~ 1200. times/min, kotero kuti pisitoni nthawi zambiri imakhudza pobowola.Kupititsa patsogolo luso la kubowola pobowola miyala.Pa nthawi yomweyi, chitoliro chobowola chimayenda pa liwiro lotsika la 35 ~ 60 RPM.Mpweya wochokera kumtunda ndi kumunsi kwa pisitoni umalowa pansi kuti uziziziritsa ndikutulutsa zodulidwa zapansi pamutu.Maonekedwe a gawo lotsuka bwino lomwe limazungulira ndi lofanana ndi la pobowola rotary ndi mpweya woponderezedwa, ndipo kagawo kamene kamagwiritsidwa ntchito ndi tungsten carbide ball tooth bit or roller cone bit.Pneumatic DTH kubowola nyundo itha kugwiritsidwa ntchito pobowola zitsime zakuya mumiyala yolimba.Liwiro lobowola ndilokwera, ndipo kuthamanga kwa kubowola sikuchepa chifukwa cha kuwonjezeka kwakuya kwakuya, ndipo dzenje lobowola ndilolunjika.

Kuti agwirizane ndi zosowa zosiyanasiyana strata pobowola bwino pobowola dzuwa, bwino pobowola cholumikizira ndi Mipikisano zolinga pobowola cholumikizira ndi zonse hayidiroliki kufala ndi kulamulira malangizo a chitukuko: ndiko, pobowola ndi zipangizo zosiyanasiyana ndi Chalk. , angagwiritse ntchito mphamvu, nyundo ya rotary ndi DTH ndi njira zina zobowola;Kuchapira chitsime chamatope, kuchapa mpweya woponderezedwa komanso kutsuka kwabwino komanso kusintha kozungulira kungagwiritsidwe ntchito.
