Momwe mphika wokulira umagwirira ntchito.
Ntchito yaikulu ya chidebe chowonjezera cha galimoto ndikusintha kuthamanga kwa mpweya mu makina oziziritsira mpweya kuti mpweya usakhale wokwera kwambiri kapena wotsika kwambiri, motero kuteteza injini. Imachita izi m'njira zingapo:
Kulekanitsa madzi ndi mpweya ndi kulamulira kuthamanga: Ketulo yowonjezera imakwaniritsa kulamulira kuthamanga kudzera mu valavu ya nthunzi pa chivindikiro chake. Pamene kuthamanga kwamkati kwa makina oziziritsira kukupitirira kuthamanga kotseguka kwa valavu ya nthunzi (nthawi zambiri 0.12MPa), valavu ya nthunzi imatseguka yokha, kulola nthunzi yotentha kulowa mu gawo lalikulu loziziritsira, motero kuchepetsa kutentha kozungulira injini ndikuwonetsetsa kuti injini ikugwira ntchito bwino.
Onjezani choziziritsira: Ketulo yowonjezera imawonjezera choletsa kuzizira kumbali yolowera madzi ya pampu kudzera mu payipi yodzaza madzi yomwe ili pansi pake kuti ipewe kutsekeka kwa mpweya komwe kumachitika chifukwa cha kuphulika kwa thovu la nthunzi pamwamba pa makina.
Ntchito yochepetsera kupanikizika: Pamene kupanikizika kwa dongosolo kupitirira mtengo womwe watchulidwa, monga kuwira, valavu yochepetsera kupanikizika ya chivindikiro idzatsegulidwa, ndipo kupanikizika kwa dongosolo kudzachotsedwa nthawi yake kuti tipewe mavuto aakulu.
Ntchito zimenezi zimagwira ntchito limodzi kuti zitsimikizire kuti makina oziziritsira galimoto akugwira ntchito bwino komanso kuti injini ikhale yotetezeka.
Chivundikiro chokulitsa sichitulutsa mpweya.
Ngati chivindikiro chowonjezera sichitulutsa mpweya, thanki yamadzi sigwira ntchito bwino, zomwe zingakhudze magwiridwe antchito abwinobwino a injini. Chivindikiro chowonjezera, chomwe chimadziwikanso kuti chivindikiro cha thanki yopanikizika, ndi gawo lofunika kwambiri la makina oziziritsira magalimoto. Ntchito yake yayikulu ndikusunga kuthamanga mu makina oziziritsira, kuphatikizapo ntchito yochepetsa kupanikizika, ndiko kuti, pamene kuthamanga mu makina kupitirira kuthamanga komwe kwatchulidwa, chivindikirocho chingatulutse kuthamanga kochulukirapo kuti kupewe kuthamanga mu makina kusakhale kwakukulu kwambiri. Ngati chivindikiro chowonjezera sichitulutsa mpweya, ndiko kuti, ntchito yochepetsa kupanikizika yalephera, izi zimapangitsa kuti kuthamanga mu makina oziziritsira kulephereke kusinthidwa bwino, zomwe zingayambitse kuti thanki yamadzi igwire ntchito molakwika, komanso kukhudza magwiridwe antchito abwinobwino a injini. Kuphatikiza apo, ngati chivindikiro chowonjezera chawonongeka kapena chosayikidwa bwino, chidzapangitsanso kuti mpweya ndi madzi ziziwonjezeka mu makina oziziritsira, zomwe zingayambitse kutentha kwambiri kwa injini, zomwe zikuwonjezera chiopsezo cha kuwonongeka kwa injini. Chifukwa chake, kusunga magwiridwe antchito abwinobwino ndi momwe chivindikiro chowonjezera chilili ndikofunikira kuti galimoto igwire ntchito bwino.
Kodi valavu yochepetsera kuthamanga kwa madzi yotenthetsera madzi ingachotsedwe?
Chokulungira cha valavu yochepetsera kupanikizika ya chotenthetsera madzi sichingachotsedwe, ndithudi, valavu yochepetsera kupanikizika nthawi zambiri imakhala yotseguka, imatha kusintha kupanikizika kwa chotenthetsera madzi, ngati chokulungira chalimbikitsidwa kupanikizika kwina kumawonjezeka, ngati chokulungira chamasulidwa kupanikizika kwina kumachepa, pambuyo pochotsa chidzakhudza kutentha kwa chotenthetsera madzi, komanso kuwononga thanki yamkati ya chotenthetsera madzi. Chidziwitso chodziwika bwino cha sayansi: 1, valavu yochepetsera kupanikizika ya chotenthetsera madzi makamaka imateteza kupanikizika kwa chotenthetsera madzi, imatha kutulutsa kupanikizika komwe kumachitika chifukwa cha chotenthetsera madzi, ndipo ingathandizenso kulamulira, nthawi zambiri ikatsekedwa, kupanikizika kwa chotenthetsera madzi kokha kumafika pafupifupi 0.7mp, valavu yochepetsera kupanikizika imachotsa kupanikizika, valavu yochepetsera kupanikizika yozungulira madzi, zimatsimikizira kuti valavu yochepetsera kupanikizika ikugwira ntchito. 2, pamene kupanikizika kuli kwakukulu kwambiri kuti kutulutsidwe, thanki yamkati ya chotenthetsera madzi imaphulika, ndipo yesetsani kusakhudza valavu yochepetsera kupanikizika kapena kulimbitsa chokulungira panthawi yogwiritsa ntchito tsiku ndi tsiku, kotero kuti valavu yochepetsera kupanikizika ili mu mkhalidwe wosintha wokha. 3, kuyika chotenthetsera madzi ngati kutuluka kwa valavu iyi kudzakhala ndi chiopsezo cha chitetezo, chotenthetsera madzi chakhala chotsekedwa ndi vacuum, kutentha kwa madzi kukapitilira kukwera, kuthamanga kudzapitirira kukwera, kuthamanga kwa madzi kukapitirira kukwera, valavu yochepetsera kuthamanga idzachita gawo lotulutsa kuthamanga, ndipo chotenthetsera chokhala ndi kuthamanga kwambiri chidzapangitsa kuti malo owetsera madzi asweke.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
