Kusiyana Pakati pa Kuyenda kwa Misa ndi Kuyenda kwa Volumetric
Kuyeza kwamadzimadzi muzinthu zolondola muzinthu zosiyanasiyana zamainjiniya ndi mafakitale, zomwe zimatsimikizira kugwira ntchito bwino komanso kuchita bwino. Pali maubwino odziwikiratu pakuyezera kuchuluka kwakuyenda kuposa kuchuluka kwa ma volumetric, makamaka kwa mpweya woponderezedwa ndi mpweya waukadaulo monga argon, co2 ndi nayitrogeni. Werengani nkhaniyi ndikuwona kuzindikira kwaukadaulo mumiyeso yonse iwiri.
Kodi mass flow ndi chiyani?
Misa flow imatanthawuza muyeso wa kuchuluka komwe kumadutsa pa nthawi ya unit. Misa imayimira chiwerengero chonse cha mamolekyu omwe akuyenda kudzera muzitsulo zinazake, osakhudzidwa ndi kusintha kwa kutentha ndi kupanikizika. Mosiyana ndi voliyumu, kuchuluka kwa gasi kumakhalabe komweko ngakhale kusinthasintha kwa chilengedwe. Kuthamanga kwa misa kumafotokozedwa mumagulu monga ma kilogalamu pa ola (kg/hr) kapena mapaundi pamphindi (lb/min); Mpweya umafotokozedwa mu ma kiyubiki mita wokhazikika pa ola (Nm³/hr) kapena ma kiyubiki mapazi pa mphindi (SCFM).
Kodi Volumetric Flow ndi chiyani?
Volumetric flow imatanthawuza kuyenda kwenikweni, kuyeza voliyumu yomwe ikuyenda pa nthawi ya unit. m3/hr, m3/min, CFM kapena ACFM ndi mayunitsi wamba akuyenda kwa volumetric, omwe amagwiritsidwa ntchito pofotokoza kukula kwake mu danga la mbali zitatu. Kuchuluka kwa mpweya kumayenderana mwachindunji ndi kutentha ndi kuthamanga. Kuchuluka kwa mpweya kumawonjezeka ndi kutentha ndi kupanikizika; m'malo mwake, imachepa ndi kuchepa kwa kutentha ndi kupanikizika. Mwa kuyankhula kwina, kutentha ndi kupanikizika kuyenera kuganiziridwa poyesa kuyenda kwa volumetric.
Kuchuluka kwa ma flow flow vs volumetric flow rate
Chidziwitso chatsatanetsatane cha kuchuluka kwa misa ndi kuchuluka kwa ma volumetric ndi kopindulitsa kusankha njira yoyenera yoyezera. Kuthamanga kwa misa kumakhala kolondola kwambiri komanso kodalirika m'machitidwe, momwe kachulukidwe kamadzimadzi amatha kusintha ndi kutentha ndi kuthamanga. Ukadaulo uwu ndiwodziwika m'mafakitale omwe amafunikira kwambiri kuwongolera moyenera zinthu zamadzimadzi, monga mankhwala ndi mafuta a petrochemical.
M'malo mwake, kuyeza kwa volumetric ndi mphamvu zokwanira m'mafakitale omwe kulondola sikuli kofunikira. Mwachitsanzo, njirayo ndi yodalirika mokwanira poyang'anira ndi kulamulira kayendedwe ka ulimi wothirira ndi madzi ogawa madzi, osatchula malipiro ovuta omwe amafunikira pokonza. Volumetric ndi njira yosavuta komanso yotsika mtengo m'mafakitale apadera. Zolakwika zitha kuchitika ngati chilengedwe sichikuyendetsedwa bwino.
Ubwino wa Misa Flow Measurement
Ubwino waukulu wogwiritsa ntchito kuyeza koyenda kwa misa umadalira kulondola kwake ndi kudalirika kwake, kuchepetsa kudalira kutentha ndi kuwongolera kuthamanga. Kugwirizana kwachindunji pakati pa kutuluka kwa misa ndi katundu wamadzimadzi kumalola kuyang'anitsitsa nthawi yeniyeni popanda zovuta zowerengera zowerengera.
Sankhani misa yoyezera kuti muwongolere molondola kwambiri. Zosankha zodziwitsidwa zitha kupangidwa ndi ogwiritsa ntchito omwe ali ndi tsiku lolondola lomwe angagwiritse ntchito kuti achepetse zinyalala komanso kukulitsa mtundu wazinthu. Kuwunika kosalekeza kwa kuchuluka kwa kayendetsedwe kake kumathandizira ogwira ntchito kusintha malinga ndi kusintha kwa mikhalidwe, ndikusiya ntchito zanu kukhala zogwira mtima komanso zogwira mtima.
Ndi liti pamene mungagwiritse ntchito mita yothamanga ya volumetric kapena mita yothamanga kwambiri?
Volumetric flow mita amalimbikitsidwa kuti agwiritse ntchito zomwe sizikufunika kulondola kwambiri. Komabe, mita ya voliyumu imafunikira chipukuta misozi kuchokera ku kutentha kowonjezera ndi kupanikizika. Pomwe zambiri zokhudza kutentha ndi kupanikizika sizikanatha kuopseza kulondola kwakukulu ndi kubwerezabwereza. Choncho, mamita othamanga kwambiri ndi odalirika komanso olondola poyerekeza ndi ma volumetric flow meters.
Ndi liti pamene mungagwiritse ntchito mita yothamanga ya volumetric kapena mita yothamanga kwambiri?
Ubwino wa mita otaya misa umakakamiza anthu omwe amazolowera ma volumetric flow metres kuti asinthe zina mwazokonza makampani apadera. Mwamwayi, n'zosavuta kupereka otaya voliyumu ndi misa otaya mita, kufika cholinga powonjezera voliyumu (aka chitoliro m'mimba mwake) kwa otaya mita.
Momwe mungasinthire misa kupita ku volumetric?
Mwina pakufunika nthawi zina kutembenuza misala kupita ku volumetric. Kutembenuka kumafikiridwa mutagwiritsa ntchito chilinganizo chowongoka, kugwiritsa ntchito milingo yoyenera mu equation yotsatirayi.
Volumetric Flow Rate=Kuchuluka kwa Kuyenda Kwambiri/Kuchulukana
Kachulukidwe kameneka kamayenderana ndi kuchuluka kwa mafunde a volumetric. Ndipo kachulukidwe amasiyana mosiyanasiyana ndi kutentha ndi kuthamanga. Momwemonso, kutentha kwakukulu kumayambitsa kachulukidwe kakang'ono ndipo kupanikizika kwambiri kumayambitsanso kutsika kwambiri. Thekuchuluka kwa volumetricimapezedwa pogawakuchuluka kwamayendedwendi kachulukidwe madzimadzi. Akuchuluka kwa volumetriczimasiyanasiyana ndi kutentha ndi kuthamanga, pamene akuchuluka kwamayendedweimakhalabe nthawi zonse pamene kutentha kapena kupanikizika kumasintha.
Njira zoyezera zoyeserera zophatikizika zokhala ndi mayankho odzipangira okha zimakulitsa magwiridwe antchito komanso mtundu wazinthu zomaliza kwambiri. Kuphatikiza apo, kuwongolera bwino kwamitengo yoyenda komanso kusanthula kwanthawi yeniyeni kumathandizira kuti ntchitoyo ikhale yabwino popanda kusokoneza njira iliyonse. Njira yolimbikitsira imakhudza magwiridwe antchito osinthika komanso kuwongolera kosalekeza.
Mwachidule, kumvetsetsa ma nuances akuyenda kwa misa ndi kuyeza kwa ma volumetric ndikofunikira kuti mukwaniritse bwino magwiridwe antchito osiyanasiyana. Pogwiritsa ntchito njira zoyenera zoyezera komanso kukumbatira mphamvu za njira iliyonse, akatswiri amatha kupititsa patsogolo ntchito zawo ndikukwaniritsa kulondola kwambiri pakuwongolera madzimadzi.
