Momwe Mavavu Olamulira a Pneamiatic Onetsetsani Kuyenda Kwambiri

Mavavu owongolera a pneamatic amapeza malamulo oyenda kwambiri kudzera munthawi ya kapangidwe kake, zigawo zenizeni, komanso mgwirizano wanzeru.

Pachiyambi chawo, mavuvu awa amatembenuza mphamvu ya chibayo (mpweya wothinikizidwa) kukhala makina opanga kudzera pa seaphragm kapena piston. Wochita sewerolo amasintha zinthu zamkati (mwachitsanzo, pulagi, malaya, kapena mpira) kuti musinthe malo oyenda, kuwongolera pang'ono madzi. Kutembenuka kumeneku ndi kothandizana kwambiri, ndi kupanikizika kwapang'onopang'ono kumatanthauza kusunthidwa bwino, kutayika maziko kuti athe.

Chinsinsi cha kulondola kwawo ndi kuphatikiza kwa oipitsa . Zida izi zimafanizira chizindikiro (nthawi zambiri 4 mpaka 20 ma, otembenuzidwa kukhala chibayo) omwe ali ndi mphamvu zenizeni) ndi malo enieni a valavu, amasintha mpweya kuti athetse zivomezi kuti zithetse zivomezi. Ndondomeko yotsekedwa iyi yotseka imawonetsetsa valavu ikamaliza ndi kukhala ndi mawonekedwe omwe akufunika, kuchepetsa zolakwika ku ± 0.1% ya kukula kwathunthu.

Konzani matalala amathandiziranso kulondola. Trum Retustations --Such monga gawo lofanana kapena mzere woyenda - zimagwiritsidwa ntchito kuntchito zofunikira. Mwachitsanzo, kuchuluka kofanananso kumapereka kusintha kofananira kudutsa mitundu ya valavu, zothandizanso kwa njira zomwe zimafunikira kuwongolera nthawi zonse zotsika komanso zazitali. Mosalala, kuchepetsa njira zotsikira mu thupi la valavu zimatetezanso kusinthasintha komwe kungasokoneze udindo.

Kugwirizana ndi machitidwe owongolera mafakitale (mwachitsanzo, DCS kapena PLC) kumathandizira kusintha kwa nthawi. Kuwunika kwa masensa, kupanikizika, kapena kutentha kwa kutentha ku kachitidweko, komwe kumasintha valavu kudzera pa woyang'anira, kuonetsetsa kuyankha mwachangu kuti asinthe kusintha.

Kukhazikika ndi kukonzanso maudindo. Amapangidwa kuchokera ku zodabwiza (mwachitsanzo, chitsulo chosapanga dzimbiri, oyang'anira osapanga dzimbiri) ndikusindikizidwa kuti athane ndi mavuto owopsa, mavuvu awa amasuntha magwiridwe antchito. Kuchita Zinthu Monga Kuyeretsa Mlengalenga kapena Ogwiritsa Ntchito Ogwirizana - amalepheretsa zolondola.

Mwakutero, mavalidwe owongolera achuma amaphatikizika, ndemanga zanzeru, ndi kusintha kapangidwe kake kuti zithetse kulondola kwa mafakitale monga mankhwala, mphamvu, ndi kupanga.
