Kuyeza kwamphamvu kosiyanasiyana kumagwira ntchito yofunika kwambiri m'mafakitale ndi malonda, chifukwa kumakhudzanso kuyang'anira ndi kuwongolera kusiyana kwa kuthamanga pakati pa mfundo ziwiri mkati mwa dongosolo. Njira yoyezera iyi sikuti imangotsimikizira chitetezo chogwira ntchito komanso imapangitsanso mphamvu zamagetsi ndikuwonetsetsa kuti zinthu ndi ntchito zikuyenda bwino. Potenthetsa, mpweya wabwino, ndi makina owongolera mpweya (HVAC), kupanikizika kosiyana kumagwiritsidwa ntchito kuwunika kukana kwa mpweya kwa mafani, zosefera, ndi ma ducts, potero kukhathamiritsa magwiridwe antchito ndikuchepetsa kugwiritsa ntchito mphamvu. Momwemonso, popanga mafuta ndi gasi, mankhwala amadzi, ndi mafakitale azamankhwala, kuyeza kwamphamvu kosiyana ndikofunikira pakuwunika kayendedwe ka madzi, fyuluta, ndi magwiridwe antchito a pampu, kuthandiza kuti magwiridwe antchito asamayende bwino ndikupewa zoopsa zomwe zingachitike.
Ma transmitters osiyanasiyana ndi zida zofunika kwambiri kuti mukwaniritse cholinga ichi. Amatha kusintha kusiyana kwa kuthamanga kwa thupi kukhala ma siginecha amagetsi, omwe amatha kugwiritsidwa ntchito poyang'anira ndi kuwongolera. Pogwiritsa ntchito zinthu zomwe zimakhudzidwa ndi kupanikizika monga ma diaphragm, ma strain gauges, kapena piezoelectric crystal transmitters amayesa molondola kusiyana kwa kuthamanga ndi kutulutsa zizindikiro za 4-20 mA kapena 0-10 V. Zizindikirozi zikhoza kuperekedwanso ku dashboards, kupeza deta. machitidwe, kapena machitidwe owongolera owunikira ndikusintha nthawi yeniyeni.
Kugwiritsa ntchito miyeso yosiyana siyana ndikokulirapo. Sizimangothandiza kuonetsetsa kuti zipangizo zamafakitale zikugwira ntchito bwino ndi njira zake, kupewa kupanikizika kwambiri ndi zoopsa zina zomwe zingagwirizane nazo komanso kumapangitsanso mphamvu zowonjezera mphamvu komanso khalidwe lazogulitsa pogwiritsa ntchito ntchito zabwino. M'makampani opanga mankhwala, kuyeza kwamakasitomala kumatsimikizira kulondola kwa fermentation ndi kusefera, kuwonetsetsa kuti chomaliza chimakwaniritsa zofunikira ndikusunga chidaliro cha ogula pamtunduwo. Chifukwa chake, pakuwona zachitetezo, magwiridwe antchito, komanso kutsimikizika kwamtundu, kupanikizika kosiyana ndi kuyeza kwake ndizofunikira kwambiri pazantchito zamakono ndi zamalonda.
Kugwiritsa Ntchito Ma Differential Pressure Transmitters
Ma transmitters osiyanasiyana ofunikira ndi zinthu zofunika kwambiri pamakampani opanga makina. Ndi kulondola kwawo komanso kukhazikika kwawo, amatenga gawo lofunikira m'mafakitale osiyanasiyana monga mafuta a petrochemicals, kupanga magetsi, zitsulo, kuthira madzi, chakudya ndi zakumwa, ndi mankhwala. Zidazi makamaka zimagwiritsa ntchito mfundo zakuthupi, monga Bernoulli equation ndi static pressure principle, kuyeza kuthamanga, kuchuluka kwamadzimadzi, komanso momwe zosefera, potero zimapereka chidziwitso chofunikira kuti zithandizire kupanga ndi kuwunika.
Muyeso woyenda ndi gawo lalikulu logwiritsira ntchito ma transmitters ophatikizika osiyanasiyana. Poyesa kusiyana kwa kuthamanga komwe kumachitika pamene madzi akuyenda kudzera mu chipangizo chogwedeza, kuthamanga kwa mafuta, gasi, nthunzi, ndi madzi ena akhoza kuwerengedwa molondola. Kuphatikiza apo, ma transmitters osiyanitsa atsimikizira kufunikira kwawo pakuyezetsa kwamadzimadzi, kuwunika molondola kuchuluka kwamadzimadzi m'matanki osungira, ma boilers, ndi ma reactors, omwe ndi ofunikira kuwonetsetsa chitetezo ndi magwiridwe antchito.
Kuyang'anira zosefera ndi ntchito ina yofunika kwambiri. Ma transmitters osiyanasiyana amawonetsa ngati fyulutayo yatsekedwa pozindikira kusintha kwa kuthamanga kwapakati pasanafike komanso pambuyo pa fyuluta, motero kuonetsetsa kuti dongosololi likugwira ntchito bwino. Kupatula kugwiritsa ntchito izi, ma transmitters osiyanasiyana amagwiritsidwanso ntchito kwambiri kuyang'anira kutuluka kwa mapaipi, momwe mapaipi amagwirira ntchito, komanso momwe ma valve alili. Poyang'anira kusintha kwa kusiyana kwa kupanikizika, amapereka chithandizo chodalirika cha deta kuti apitirize kugwira ntchito bwino.
Ma transmitters osiyanasiyana amakhalanso ndi gawo lofunikira pakuwunika zachilengedwe, makamaka pakuwunika momwe mpweya ulili. Poyesa kusiyana kwa kuthamanga pakati pa malo osiyanasiyana mumlengalenga, zidazi zimatha kuwerengera molondola kuthamanga kwa mpweya ndi voliyumu, potero kuyang'anira kuchuluka kwa zinthu monga PM2.5 ndi PM10, ndi mpweya monga SO2 ndi NO2. Kuphatikiza apo, amagwira ntchito yofunika kwambiri pakuwunika kutulutsa kwamafuta m'mafakitale, utsi wamagalimoto, komanso mpweya wamkati wamkati.
Poyang'anira zipinda zoyeretsa, ma transmitters ophatikizika amawonetsetsa kuti ukhondo wa mpweya umakwaniritsa miyezo powunika kusiyana kwapakatikati mkati mwa zipinda zoyera, zomwe ndizofunikira pakuwongolera bwino m'makampani opanga mankhwala, zamagetsi, ndi zakudya. Kupitilira kuwunika kwa mpweya, ma transmitterwa amagwiritsidwanso ntchito powunika momwe madzi amayendera, chinyezi cha nthaka, komanso kuwunika kwanyengo, kuwonetsa kusinthasintha kwawo pantchito yowunikira zachilengedwe.
Chifukwa cha kuyeza kwawo kwakukulu (mpaka 0.1% -0.5%), kukhazikika kwanthawi yayitali, komanso kusiyanasiyana kogwiritsa ntchito, kuphatikizidwa ndi kuyika bwino ndi kukonza, ma transmitters osiyanitsa akhala zida zofunika kwambiri pakuwunika chilengedwe. Pamene kuzindikira zachitetezo cha chilengedwe kukuchulukirachulukira, zikuyembekezeredwa kuti ma transmitters osiyanasiyana aziwona ntchito zambiri mtsogolomu. Ndi kupita patsogolo kwaukadaulo, momwe amayezera komanso kuchuluka kwa momwe amagwiritsidwira ntchito akuyembekezeka kukulirakulira, ndikupereka chithandizo cholondola komanso chodalirika cha data pakuteteza chilengedwe.
Kuwerengera Kusiyana kwa Pressure
Kuwerengera kuthamanga kwa masiyanidwe ndi gawo lofunikira kwambiri pantchito zamafakitale ndi zamalonda, makamaka pakuyezera kuyenda, kuyeza kwamadzimadzi, komanso kuwunika masefa. Kupanikizika kosiyana, kusiyana kwa kukakamiza pakati pa mfundo ziwiri mkati mwa dongosolo, ndilo lingaliro lalikulu la thupi. Mawerengedwe ake ndi osavuta koma othandiza: kuthamanga kwapadera (Pd) ndikofanana ndi kuthamanga kwa mbali (Ph) kuchotsera kutsika kwapambali (Pl), ndipo kumatha kufotokozedwa m'mayunitsi osiyanasiyana monga Pascal (Pa), mapaundi pa inchi imodzi (PSI). ), kapena bar.
Kuwerengera kupanikizika kosiyana kumaphatikizapo njira zingapo zofunika: choyamba ndikukonzekera, kuonetsetsa kukhazikitsidwa kolondola ndi kulumikizana kwa chotengera chosiyana; chotsatira ndikuchita kuwerengera, kupeza zotsatira kudzera mu njira yosiyana ya kuthamanga; potsiriza, kutembenuza mayunitsi ngati kuli kofunikira. Mwachitsanzo, ngati kupanikizika kwambiri kwa dongosolo ndi 100 PSI ndipo kutsika kwapakati ndi 50 PSI, ndiye kuti kusiyana kwake ndi 50 PSI.
Kulondola kwa kuyeza kwamphamvu kosiyanasiyana kumatengera zinthu zosiyanasiyana, kuphatikiza kulondola kwa sensa, kutulutsa komwe kungachitike, kusintha kwa kutentha kwa chilengedwe, ndi kugwedezeka. Kuphatikiza apo, kutengera kugwiritsa ntchito, pali mitundu yosiyanasiyana ya ma transmitters ophatikizika, monga capacitive, piezoresistive, ndi piezoelectric, iliyonse yogwirizana ndi malo ndi zofunikira zina.
Kuthamanga kwamitundu yosiyanasiyana ndikotambasula kwambiri, osati kungoyang'anira kayendedwe, kuchuluka kwamadzimadzi, ndi zosefera, komanso kumaphatikizanso kuwongolera kukakamiza pakati pamadera ena. Kuyeza kwamphamvu kosiyanasiyana ndikofunikira pakuwonetsetsa kuti ntchito zamakampani zikuyenda bwino, kuwongolera magwiridwe antchito a zida, ndikuwonetsetsa kuti chitetezo pakupanga. Chifukwa chake, kumvetsetsa mfundo zoyambira za kukakamiza kwa masiyanidwe, njira zowerengera, ndi gawo lake pamagwiritsidwe osiyanasiyana ndi luso lofunikira komanso lofunikira kwa mainjiniya ndi akatswiri aluso.
