Duo Yabwino Kwambiri: Vavu ya Mpira Wamagulu Awiri ndi Magetsi Amagetsi

Duo Yabwino Kwambiri: Vavu ya Mpira Wamagulu Awiri ndi Magetsi Amagetsi

Mawonekedwe a mavavu awiri a mpira

Ma valve awiri a mpira amapangidwa ndi magawo awiri, omwe ndi osavuta kusamalira ndikusintha. Mapangidwe awo apadera a magawo awiri amalola kuti pakhale m'malo mwa intaneti pazigawo zamkati, zomwe zimachepetsa kwambiri nthawi yochepetsera dongosolo ndi kukonza ndalama. Ma valve a mpira amapereka njira yowongoka yowongoka ndi kukana kwamadzi otsika, ndipo amatha kuchepetsa chipwirikiti chamadzimadzi ndi kung'anima, kuonetsetsa kuwongolera kokhazikika. Kuonjezera apo, ma valve awiri a mpira ali ndi ntchito yabwino kwambiri yosindikiza ndipo ndi yoyenera pazochitika zosiyanasiyana zogwirira ntchito, kuphatikizapo kutentha kwakukulu, malo othamanga kwambiri komanso zofalitsa zosiyanasiyana zowononga.

Ubwino wa ma actuators amagetsi

Ma actuators amagetsi amayendetsedwa ndi ma motors kuti athe kuwongolera bwino kutsegulira ndi kutseka kwa ma valve, omwe amatha kuyankha mwachangu komanso kuwongolera molondola kwambiri. Nthawi zambiri amakhala ndi zida zamagetsi zamagetsi kuti azithandizira kuyang'anira ndi kuyang'anira kutali, kotero kuti njira yowongolera imatha kuphatikizidwa ndi makina apamwamba kwambiri. Poyerekeza ndi ma pneumatic kapena hydraulic actuators, ma actuators amagetsi ndi osavuta kuyiyika ndikuwongolera, komanso amakhala ndi mphamvu zambiri.

Njira zoyendetsera bwino

Kuphatikiza ma valve awiri a mpira ndi magetsi oyendetsa magetsi amatha kukwaniritsa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Makina opangira magetsi amatha kupereka mayankho azizindikiro za 4-20mA, kuzindikira kuwunika kwenikweni kwa malo a valve, ndikuwongolera molondola kuthamanga kwa ma valve posintha kutsegulidwa kwa valve. Makhalidwe anzeru a kuphatikiza uku amatanthauza kuti itha kuyendetsedwa pakati kudzera mu dongosolo la SCADA (Supervisory Control and Data Acquisition), kuzindikira kusamalidwa molosera, ndikuchepetsa kulephera.

Milandu Yofunsira

Kutengera mafakitale amafuta ndi gasi monga mwachitsanzo, ma valve amitundu iwiri amagwiritsidwa ntchito kwambiri munjira zazikulu monga mapaipi amafuta ndi makina ojambulira gasi okhala ndi zida zamagetsi. Muzochitika zotere zogwiritsira ntchito, makina oyendetsa magetsi amatha kuyankha mwamsanga malangizo owongolera, kusintha mlingo wotsegulira wa valve ya mpira, ndikuwonetsetsa kuperekedwa molondola kwa mafuta osakanizika kapena gasi. Panthawi imodzimodziyo, m'makampani opanga mankhwala, kuphatikiza kumeneku kumakhalanso kofala pochiza ndi kunyamula mankhwala owononga. Kuwongolera kolondola komwe kumaperekedwa ndi woyendetsa magetsi kumatsimikizira kukhazikika ndi chitetezo cha njira yochizira mankhwala.

Mapeto

Kuphatikizika kwabwino kwa ma valve awiri a mpira ndi magetsi oyendetsa magetsi sikungowonjezera kuwongolera ndi kuwongolera bwino, komanso kumawonjezera kudalirika ndi chitetezo cha dongosolo. Kuphatikiza uku ndikupita patsogolo kwakukulu pazantchito zamafakitale. Imakwaniritsa miyezo yapamwamba yamakampani amakono pakuwongolera njira, komanso kuchepetsa ndalama zogwirira ntchito ndi kukonza. Pamene ukadaulo wa mafakitale akupitilira kupita patsogolo, titha kuyembekezera kuti njira zina zatsopano zituluke, ndikupititsa patsogolo kuwongolera kwachitetezo cha mafakitale ndi chitetezo.
