Valve yodzichitira ndi mtundu wa valavu kuti basi kusintha otaya, kuthamanga, kutentha ndi magawo ena malinga ndi kusintha magawo dongosolo, amene chimagwiritsidwa ntchito mafuta, makampani mankhwala, zitsulo, zomangamanga ndi mafakitale ena. Pepalali lisanthula mfundo yogwirira ntchito ndi njira yowongolera ya valavu yodziwikiratu kuchokera ku mbali ziwiri.
Choyamba, mfundo ntchito
Mfundo yogwiritsira ntchito valavu yodziwikiratu makamaka kudzera mu sensa kuti izindikire kusintha kwa magawo a dongosolo, chizindikiro chodziwika chimaperekedwa kwa actuator, actuator imasintha kutsegula kwa valve molingana ndi chizindikiro, kuti akwaniritse kusintha kwa kayendedwe ka kayendedwe kake. , kuthamanga, kutentha ndi zina.
1 Sensor: Sensa ndi chipangizo chomwe chimasintha kuchuluka kwa thupi m'dongosolo (monga kutentha, kuthamanga, kutuluka, etc.) kukhala zizindikiro zamagetsi. Sensa wamba ndi thermocouples, resistors kutentha, mphamvu masensa, masensa otaya ndi zina zotero.
2. Actuator: The actuator ndi chipangizo chomwe chimasintha zizindikiro zamagetsi kuti zikhale zoyenda zamakina ndipo zimagwiritsidwa ntchito pokonza kutsegula kwa valve. Ma actuators wamba ndi ma actuators amagetsi, ma pneumatic actuators, ma hydraulic actuators ndi zina zotero.
3. Valve: Valve ndi chipangizo chomwe chimayendetsa kuthamanga, kuthamanga, kutentha ndi zina zapakati pamadzi. Mavavu wamba ndi ma valve a globe, ma valve owongolera, ma valve otetezera, ma valve ochepetsa kuthamanga ndi zina zotero.
2. Control mode
Njira zowongolera ma valve otomatiki makamaka ndi awa:
1. Kutsegula kotsegula: Posintha kutsegula kwa valve, sinthani kayendedwe, kuthamanga, kutentha ndi zina zapakati pamadzi. Njira zowongolera zotsegulira zodziwika bwino zimaphatikizapo kuwongolera kutsegulira kwamanja, kuwongolera kutsegulira kwamagetsi, kuwongolera kutsegulira kwa pneumatic ndi zina zotero.
2. Kuwongolera pang'ono: kutsegula kwa valve kumayendetsedwa pamalo okhazikika kuti azitha kuyendetsa, kuthamanga, kutentha ndi zina zapakati pamadzi. Njira zodziwika bwino zowongolera pang'ono zimaphatikizapo kuwongolera pang'ono, kuwongolera kwamagetsi, kuwongolera kwa pneumatic ndi zina zotero.
3. Kuwongolera kusintha: Mwa kusintha kutsegula kwa valve, kuthamanga, kuthamanga, kutentha ndi zina za sing'anga yamadzimadzi zimatha kusinthidwa mosalekeza. Njira zowongolera zodziwika bwino zimaphatikizira kuwongolera kofananira-kusiyana (PID), kuwongolera movutikira, kuwongolera ma neural network ndi zina zotero.
4. Kuwongolera mwanzeru: Kupyolera mu kugwiritsa ntchito luso lamakono lanzeru, kukwaniritsa kuwongolera mwanzeru kwa mavavu odziwikiratu. Njira zodziwika bwino zowongolera mwanzeru zimaphatikizapo kachitidwe ka akatswiri, ma genetic algorithm, artificial neural network ndi zina zotero.
Pomaliza, mfundo yogwirira ntchito ya valavu yodziwikiratu ndikuzindikira kusintha kwa magawo a dongosolo kudzera pa sensa, kutumiza chizindikiro chomwe chapezeka kwa actuator, ndipo chowongolera chimasintha kutseguka kwa valavu molingana ndi chizindikirocho, kuti azindikire zodziwikiratu. kusintha kwa kayendedwe, kuthamanga, kutentha ndi zina. Njira zoyendetsera ma valve odzipangira makamaka zimaphatikizapo kutsegulira, kuwongolera pang'ono, kuwongolera kusintha ndi kuwongolera mwanzeru, ndi zina. Njira zowongolera izi zimatha kukwaniritsa zofunikira zowongolera ma valve odziyimira pawokha pamikhalidwe yosiyanasiyana yogwirira ntchito.
