An oscillating controlvalavuzingawoneke ngati gwero la kusakhazikika kwa ulamuliro ndipo ntchito zokonzanso nthawi zambiri zimangoyang'ana pamenepo. Izi zikalephera kuthetsa vutoli, kufufuza kwina nthawi zambiri kumatsimikizira kuti ma valve ndi chizindikiro cha vuto lina. Nkhaniyi ikufotokoza za njira zothetsera mavuto kuti athandize ogwira ntchito kubzala kuti adutse zodziwikiratu ndikupeza zomwe zimayambitsa zovuta zowongolera.
"Valovu yatsopano yowongolera ikugwiranso ntchito!" Mawu ofananirako adanenedwa ndi zikwizikwi za ogwiritsa ntchito zipinda zowongolera padziko lonse lapansi. Chomeracho sichikuyenda bwino, ndipo ogwira ntchito amafulumira kudziŵa wolakwayo—valavu yodziŵika posachedwapa, yosachita bwino. Zitha kukhala zopalasa njinga, zitha kukhala zikulira, zitha kumveka ngati zili ndi miyala, koma ndiye chifukwa chake.
Kapena kodi? Pothetsa zovuta zowongolera, ndikofunikira kukhala ndi malingaliro otseguka ndikuyang'ana kupyola zodziwikiratu. Ndi chibadwa cha anthu kuimba mlandu “chinthu chotsiriza chimene chinasintha” chifukwa cha vuto lina lililonse limene lachitika. Ngakhale kuti machitidwe olakwika a valve amatha kukhala odetsa nkhawa, chifukwa chenichenicho nthawi zambiri chimakhala kwina.

Zitsanzo zotsatirazi zikusonyeza mfundo imeneyi.
Kukuwa Control Valve. Valavu yopopera yopopera kwambiri inali ikulira pambuyo pa miyezi ingapo yautumiki. Vavuyo idakokedwa, kufufuzidwa, ndipo idawoneka kuti ikugwira ntchito bwino. Atabwerera kuntchito, kulira kunayambiranso, ndipo chomeracho chinafuna kuti "valavu yowonongeka" ilowe m'malo.
Wogulitsayo adaitanidwa kuti akafufuze. Kufufuza pang'ono kunasonyeza kuti valavu ikuyendetsedwa ndi kayendetsedwe ka kayendetsedwe kake pakati pa 0% ndi 10% yotsegulidwa pa mlingo wa 250,000 pachaka. Kuthamanga kwapamwamba kwambiri pakuyenda kotsika koteroko ndi kutsika kwamphamvu kwambiri kunayambitsa vutoli. Kusintha kwa kuwongolera kwa loop ndikugwiritsanso ntchito pang'ono kumbuyo kwa valve kunayimitsa njinga ndikuchotsa ma squeals.
Kuyankha kwa Jumpy Valve. Valavu yobwezeretsanso madzi a boiler inali itakhazikika pampando poyambira. Vavu ikayamba kutsika pampando, imadumphira motseguka, ndikupanga kusokonezeka kwamphamvu chifukwa chakuyenda kosalamulirika.
Wogulitsa valavu adaitanidwa kuti adziwe valavu. Kuwunika kunayendetsedwa ndipo kukakamiza kwa mpweya kunapezeka kuti kumayikidwa pamwamba pa ndondomeko komanso kuwirikiza kanayi kuposa momwe zimafunikira kuti mukhale ndi malo okwanira. Vavu itakokedwa kuti iwunikenso, akatswiri adapeza kuti pampando ndi mphete zapampando zidawonongeka chifukwa cha mphamvu yamagetsi yochulukirapo, zomwe zidapangitsa kuti pulagi ya valavu ipachike. Zigawozo zidasinthidwa, mphamvu yotulutsa mpweya idatsitsidwa, ndipo valavu idabwezedwa kuti igwire ntchito momwe idapangidwira.
