Kulephera kofala kwa mavavu a pneumatic

Valavu ya pneumatic imatanthawuza kwambiri silinda yomwe imasewera gawo la actuator, kudzera mu mpweya woponderezedwa kuti ipange gwero lamphamvu loyendetsa valavu, kuti akwaniritse cholinga chowongolera kusintha. Pamene payipi yosinthidwa imalandira chizindikiro chowongolera chomwe chimapangidwa kuchokera ku makina oyendetsa okha, magawo oyenerera (monga: kutentha, kuthamanga, kuthamanga, etc.) zidzasinthidwa.

Valve yathu ya TWS imatha kuperekamphira wokhala ndi butterfly valve, monga mtundu wa wafer, valavu yagulugufe ya lug, valavu ya butterfly eccentric,valve pachipata, valavu ya mpira, valavu yoyendera ndi zina zotero. Opaleshoniyi ikuphatikizapo pneumatic actuator.

Valve ya pneumatic makamaka ili ndi ubwino wotsatirawu: choyamba, valve ya pneumatic imayenda mofulumira ndipo lamulo lokonzekera likhoza kumalizidwa mu nthawi yochepa; chachiwiri, valavu ya pneumatic ikhoza kukhala mphamvu yoyendetsa ya silinda yayikulu kuti ikwaniritse makokedwe akulu; chachitatu, valavu ya pneumatic ikhoza kukhala pamalo otetezeka komanso okhazikika kwa nthawi yayitali pansi pa zovuta zamtundu uliwonse.

Kulakwitsa kofala kwa ma valve pneumatic

1 Kuchulukitsa ndi kutayikira kwa valavu ya pneumatic

Kuchuluka kwa kutayikira kwa valavu ya pneumatic makamaka kumadalira kusintha kwa valve. Kuwonjezeka kwa kutuluka kwa valve ya pneumatic makamaka chifukwa cha zinthu ziwiri zotsatirazi: choyamba, kuvala kwa chitseko cha valve pneumatic; ngati valavu imasakanizidwa ndi zinthu zakunja kapena tchire lamkati likuphwanyidwa, kapena pansi pa ulamuliro wa kupanikizika pakati pa zofalitsa, pamene kusiyana kwapakati papakati kuli kwakukulu, chifukwa valavu singakhoze kutsekedwa kwathunthu, ndipo pamapeto pake imayambitsa kutuluka kwa mpweya. valavu ya pneumatic yowonjezera.

2 Kulakwitsa kosakhazikika kwa valve ya pneumatic ndi chifukwa chake

Kusasunthika kosasunthika kwa chizindikiro komanso kutulutsa mpweya kungayambitse kuti valavu ya pneumatic ikhale yosakhazikika. Kuthamanga kwa chizindikiro kosasunthika kudzachititsa kuti kusasunthika kosasunthika kwa wolamulira, ndipo pamene mpweya wa mpweya umakhala wosasunthika, valve yochepetsera mphamvu idzalephera chifukwa cha mphamvu yaing'ono ya compressor. N'zothekanso kuti valavu ya pneumatic chifukwa cha kusiyana pakati pa wina ndi mzake ndi yosakhazikika pamene malo a amplifier spray baffle sali ofanana. Kuphatikiza apo, chitoliro cholimba chotulutsa kapena mzere wotulutsa umapangitsanso kusakhazikika kwa valavu ya pneumatic; valavu ya mpira wa amplifier idzakhudzanso kukhazikika kwa valve ya pneumatic.

3.Kulephera kwa valve ya pneumatic ndi chifukwa chake
Mavavu a pneumatic amatha kukhudzidwa ndi zinthu zachilengedwe zomwe zimagwira ntchito. Pambuyo pa bushing ndi ntchito yapakati pa valve kwa nthawi yayitali, pansi pa kukangana, ziwirizo zimapanga ming'alu, kukhalapo kwa kugwedezeka kwina kuzungulira valavu ya pneumatic, kusalinganika kwa malo a pneumatic valve kumayambitsa kugwedezeka kwa valve pneumatic. . Kuonjezera apo, pamene kukula kwa valve ya pneumatic kumasankhidwa molakwika kapena njira yotsekera ya valavu ya mpando umodzi sikugwirizana ndi kayendetsedwe ka kayendedwe kapakati, valve ya pneumatic idzagwedezekanso.

4 Pneumatic valve action pang'onopang'ono kulephera komanso chifukwa

Kufunika kwa tsinde sikukayikitsa panthawi ya kayendedwe ka valve pneumatic. Pamene tsinde la valve likupindika, kukangana komwe kumachitika chifukwa cha kayendetsedwe kake kozungulira kudzawonjezeka, zomwe zimapangitsa kuti valavu ya pneumatic ikhale yochedwa. Pamene mafuta opaka mafuta a graphite ndi asbestos, kudzaza kwa polytetrafluoroethylene kumakhala kwachilendo kumapangitsanso kuti valavu ya pneumatic ichitike pang'onopang'ono, valavu ya pneumatic mukakhala fumbi mkati mwa valavu, valavu ya pneumatic yoyikidwa ndi position-er, etc. kukana ntchito, motero kumayambitsavalavu ya butterfly ya pneumaticzochita pang'onopang'ono.
