Kuvumbulutsa Chinsinsi cha Centrifugal Compressor Head Coefficient

Mu dziko la makina a mafakitale, centrifugal kompresas imagwira ntchito yofunika kwambiri pa ntchito zosiyanasiyana, kuyambira mafakitale opanga mafuta mpaka malo opangira magetsi. Chimodzi mwa zinthu zofunika kwambiri zomwe zimatsimikiza momwe ntchito yakompresa wa centrifugalndi mutu wokwanira. M'nkhaniyi, tifufuza mozama za mutu wokwanira, chifukwa chake uli wofunika, komanso momwe umakhudzira magwiridwe antchito a makina ofunikira awa.

Kodi Mutu Wokwanira Ndi Chiyani Kwenikweni?

Mutu wa coefficient wa a choponderezedwa cha centrifugalrndi kuchuluka kopanda muyeso komwe kumapereka chidziwitso chofunikira pa momwe compressor imagwirira ntchito. Ndi muyeso wa ubale womwe ulipo pakati pa mphamvu zomwe zimaperekedwa ku madzi ndi Chokompressor AKupeza liwiro la impeller pa dayamita yake yakunja. Mwachidule, zimathandiza mainjiniya ndi ogwiritsa ntchito kumvetsetsa momwe compressor ikusinthira mphamvu yamakina kukhala mphamvu yokakamiza ya madzi omwe akukanikizidwa.

Mwa masamu, coefficient ya mutu (ψ) imawerengedwa pogwiritsa ntchito fomula iyi: ψ = (gH) / u₂², pomwe g ndi kuthamanga chifukwa cha mphamvu yokoka, H ndi mutu wa compressor (mphamvu pa kulemera kwa unit ya madzi), ndipo u₂ ndi liwiro la impeller. Fomula iyi imalola kufananiza kokhazikika kwa magwiridwe antchito a compressor m'mapangidwe osiyanasiyana ndi mikhalidwe yogwirira ntchito.

Nchifukwa chiyani Mutu wa Coefficient Ndi Wofunika?

Kuchuluka kwa mphamvu ya mutu ndikofunikira kwambiri pazifukwa zingapo. Choyamba, ndi chinthu chofunikira kwambiri pakudziwa momwe compressor imagwirira ntchito. Kuchuluka kwa mphamvu ya mutu kumasonyeza kuti compressor imatha kukweza mphamvu ya injini pa liwiro la impeller, zomwe zikutanthauza kuti mphamvu zochepa zimawonongeka panthawi yopondereza. Izi sizimangochepetsa ndalama zogwirira ntchito komanso zimapangitsa compressor kukhala yotetezeka ku chilengedwe pochepetsa kugwiritsa ntchito mphamvu.

Kachiwiri, zimathandiza pakupanga ndi kusankha ma compressor a centrifugal. Mainjiniya amatha kugwiritsa ntchito head coefficient ngati muyezo woyerekeza mitundu yosiyanasiyana ya compressor ndikusankha yomwe ikugwirizana bwino ndi zofunikira za ntchito inayake. Mwachitsanzo, mu ntchito zomwe ma ratios okwera kwambiri amafunika, compressor yokhala ndi head coefficient yapamwamba ingagwiritsidwe ntchito.

Kuphatikiza apo, chiŵerengero cha mutu chimathandizanso poneneratu momwe compressor imagwirira ntchito pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito. Pomvetsetsa momwe chiŵerengero cha mutu chimasinthira malinga ndi zinthu monga kuchuluka kwa madzi, kutentha, ndi kupanikizika, ogwiritsa ntchito amatha kukonza bwino ntchito ya compressor kuti atsimikizire kuti ikugwira ntchito bwino komanso yodalirika.

Zotsatira pa Ntchito ya Compressor

Mutu wa coefficient umakhudza mwachindunji mbali zosiyanasiyana za kompresa wa centrifugalntchito. Mwachitsanzo, zimakhudza kukwera kwa kuthamanga kwa mpweya pa compressor. Kuchuluka kwa mphamvu ya mpweya kumatanthauza kuti compressor imatha kupanga kusiyana kwakukulu kwa kuthamanga kwa mpweya, komwe ndikofunikira pa ntchito monga kunyamula gasi ndi kuzizira.

Zimakhudzanso kukhazikika kwa compressor. Ma compressor okhala ndi head coefficient yodziwika bwino amatha kugwira ntchito mokhazikika pamitundu yosiyanasiyana ya kayendedwe ka madzi. Izi zili choncho chifukwa head coefficient imathandiza kusunga bwino pakati pa kuthamanga ndi kayendedwe ka madzi a compressor, kupewa mavuto monga kukwera ndi kutsamwa.

Kuphatikiza apo, kuchuluka kwa mphamvu ya mutu kumatha kukhudza kuwonongeka ndi kung'ambika kwa zigawo za compressor. Ma compressor omwe amagwira ntchito pa kuchuluka kwa mphamvu ya mutu amatha kukhala ndi nkhawa kwambiri pa impeller ndi ziwalo zina, zomwe zingayambitse kufunikira kowonjezereka kosamalira ndi moyo wautali ngati sakuyang'aniridwa bwino.

Mapeto

Kuchuluka kwa mphamvu ya centrifugal compressor ndi chinthu chofunikira kwambiri chomwe chimagwira ntchito yofunika kwambiri pozindikira momwe makina ofunikirawa amagwirira ntchito, momwe amagwirira ntchito, komanso kudalirika. Pomvetsetsa momwe mphamvu ya head coefficient ilili komanso momwe imakhudzira magwiridwe antchito a compressor, mainjiniya ndi ogwiritsa ntchito amatha kupanga zisankho zolondola pankhani yopanga, kusankha, ndi kugwiritsa ntchito ma compressor a centrifugal. Pamene kufunikira kwa makina opondereza ogwira ntchito bwino komanso odalirika kukupitilira kukula m'mafakitale osiyanasiyana, kumvetsetsa mozama kwa mphamvu ya head coefficient kudzakhala kofunikira kuti zitsimikizire kuti ma compressor a centrifugal akugwira ntchito bwino m'zaka zikubwerazi. Chifukwa chake, nthawi ina mukakumana ndi compressor ya centrifugal, kumbukirani kufunika kwa mphamvu ya head coefficient ndi momwe imakhudzira magwiridwe antchito onse a makina odabwitsa awa.
