Mfundo yogwirira ntchito komanso njira yokonza ndi kukonza zolakwika za valavu ya gulugufe wa pneumatic

Valavu ya gulugufe wa pneumaticIli ndi choyatsira mpweya ndi valavu ya gulugufe. Vavu ya gulugufe ya pneumatic imagwiritsa ntchito mbale yozungulira ya gulugufe yomwe imazungulira ndi tsinde la valavu kuti itsegule ndi kutseka, kuti igwire ntchito. Vavu ya pneumatic imagwiritsidwa ntchito makamaka ngati valavu yotseka, ndipo ikhozanso kupangidwa kuti ikhale ndi ntchito yosinthira kapena valavu ya gawo ndi kusintha. Pakadali pano, valavu ya gulugufe imagwiritsidwa ntchito pamavuto otsika komanso akuluakulu. Imagwiritsidwa ntchito kwambiri pamapaipi apakati.

Mfundo yogwirira ntchito yavalavu ya gulugufe ya pneumatic

Mbale ya gulugufe ya valavu ya gulugufe imayikidwa mbali ya m'mimba mwake ya payipi. Mu njira yozungulira ya thupi la valavu ya gulugufe, mbale ya gulugufe yooneka ngati disc imazungulira mozungulira mzere, ndipo ngodya yozungulira ili pakati pa 0°-90°Pamene kuzungulira kufika pa madigiri 90°, valavu ili yotseguka kwathunthu. Vavu ya gulugufe ndi yosavuta kapangidwe kake, yaying'ono kukula kwake komanso yopepuka kulemera kwake, ndipo ili ndi zigawo zochepa chabe. Kuphatikiza apo, imatha kutsegulidwa ndi kutsekedwa mwachangu pozungulira 90 yokha.°, ndipo ntchito yake ndi yosavuta. Nthawi yomweyo, valavu imakhala ndi makhalidwe abwino owongolera madzi. Vavu ya gulugufe ikatseguka bwino, makulidwe a mbale ya gulugufe ndiye okhawo omwe amalimbana ndi njira yolumikizira madzi ikadutsa m'thupi la valavu, kotero kutsika kwa kuthamanga komwe kumapangidwa ndi valavu kumakhala kochepa kwambiri, kotero kumakhala ndi makhalidwe abwino owongolera kuyenda kwa madzi. Mavalavu a gulugufe ali ndi mitundu iwiri yotsekera: chisindikizo cholimba ndi chisindikizo chachitsulo. Pa mavalavu otsekera olimba, mphete yotsekera imatha kuyikidwa pa thupi la valavu kapena kumangiriridwa kumphepete mwa mbale ya gulugufe.

Valavu ya gulugufe ya Pneumatickukonza ndi kukonza zolakwika

1. Ndondomeko yowunikira ndi kukonza masilinda

Kawirikawiri chitani bwino ntchito yoyeretsa pamwamba pa silinda ndikupaka mafuta kuzungulira kwa shaft ya silinda. Tsegulani chivundikiro cha silinda nthawi zonse miyezi 6 iliyonse kuti muwone ngati pali zouma ndi chinyezi mu silinda, komanso ngati mafuta ali bwino. Ngati mafuta opaka akusowa kapena auma, ndikofunikira kusokoneza silinda kuti ikonzedwe bwino komanso kutsukidwa musanawonjezere mafuta opaka.

2. Kuyang'ana thupi la valavu

Miyezi 6 iliyonse, yang'anani ngati thupi la valavu lili bwino, ngati pali kutuluka kwa madzi pa flange yoyikira, ngati kuli koyenera, yang'anani ngati chisindikizo cha thupi la valavu chili bwino, palibe kuwonongeka, ngati mbale ya valavu ndi yosinthasintha, komanso ngati pali zinthu zina zakunja zomwe zakodwa mu valavu.

Njira zochotsera ndi kusonkhanitsa ma cylinder block ndi zodzitetezera:

Choyamba chotsani silinda kuchokera ku thupi la valavu, choyamba chotsani chivundikiro kumapeto onse a silinda, samalani ndi komwe pistoni imalowera mukachotsa pistoni, kenako gwiritsani ntchito mphamvu yakunja kuzungulira silinda mozungulira kuti pistoni iyende mbali yakunja, kenako tsekani valavu. Dzenje limapumira pang'onopang'ono ndipo pistoni imakankhidwira kunja pang'onopang'ono ndi mpweya, koma njira iyi iyenera kusamala kuti mpweya utuluke pang'onopang'ono, apo ayi pistoni idzatuluka mwadzidzidzi, zomwe ndi zoopsa pang'ono! Kenako chotsani circlip pa silinda, ndipo silinda ikhoza kutsegulidwa kuchokera kumapeto ena. Tulutsani. Kenako mutha kuyeretsa gawo lililonse ndikuwonjezera mafuta. Zigawo zomwe ziyenera kupakidwa mafuta ndi: khoma lamkati la silinda ndi mphete yosindikizira ya pistoni, choyimitsa ndi mphete yakumbuyo, komanso shaft ya giya ndi mphete yosindikizira. Mukapaka mafuta, mafuta ayenera kuyikidwa motsatira dongosolo lochotsera ndi dongosolo losinthira la zigawo. Pambuyo pake, ayenera kuyikidwa motsatira dongosolo lochotsera ndi dongosolo losinthira la zigawo. Samalani malo a giya ndi chogwirira, ndipo onetsetsani kuti pisitoni yachepa kufika pamalo pomwe valavu yatsegulidwa. Mzere womwe uli kumapeto kwa giya umafanana ndi chipika cha silinda mkati mwa malo, ndipo mzere womwe uli kumapeto kwa giya umalunjika ku chipika cha silinda pamene pisitoni yatambasulidwa kufika pamalo akunja pamene valavu yatsekedwa.

Kukhazikitsa ndi kukonza thupi la silinda ndi ma valavu ndi njira zodzitetezera:

Choyamba ikani valavu mu mkhalidwe wotsekedwa ndi mphamvu yakunja, ndiko kuti, tembenuzani shaft ya valavu mozungulira mpaka mbale ya valavu itakhala yotseka ndi mpando wa valavu, ndipo nthawi yomweyo ikani silinda mu mkhalidwe wotsekedwa (ndiko kuti, valavu yaying'ono pamwamba pa shaft ya silinda. Mzerewo ndi wolunjika ku thupi la silinda (la valavu yomwe imazungulira mozungulira kuti itseke valavu), kenako ikani silinda ku valavu (njira yoyikira ikhoza kukhala yofanana kapena yolunjika ku thupi la valavu), kenako yang'anani ngati mabowo a screw ali ofanana. Kupotoka kwakukulu, ngati pali kupotoka pang'ono, ingotembenuzani block ya silinda pang'ono, kenako limbitsani zomangira. Kukonza valavu ya gulugufe ya pneumatic choyamba yang'anani ngati zowonjezera za valavu zayikidwa kwathunthu, valavu ya solenoid ndi muffler, ndi zina zotero, ngati sizili kwathunthu, musasinthe, mpweya wabwinobwino ndi 0.6MPA±0.05MPA, musanagwiritse ntchito, onetsetsani kuti palibe zinyalala zomwe zakodwa mu mbale ya valve m'thupi la valve. Mukayamba kugwira ntchito, gwiritsani ntchito batani logwiritsira ntchito pamanja la valavu ya solenoid (chophimba cha valavu ya solenoid chimazimitsidwa panthawi yogwira ntchito pamanja, ndipo ntchito yamanja ndi yovomerezeka; pamene ntchito yowongolera magetsi ikuchitika, kupotoza pamanja kumayikidwa pa 0 ndipo chophimba chimazimitsidwa, ndipo ntchito yamanja ndi yovomerezeka; 0 malo 1 ndikutseka valavu, 1 ndikutsegula valavu, ndiko kuti, valavu imatsegulidwa magetsi akayatsidwa, ndipo valavu imatsekedwa magetsi akazima.

Ngati zapezeka kuti wopanga ma valve a gulugufe opumira amakhala pang'onopang'ono kwambiri pamalo oyamba a kutsegula kwa valve panthawi yoyambitsa ndi kugwira ntchito, koma amakhala mofulumira kwambiri akangoyenda. Mwachangu, pankhaniyi, valavu yatsekedwa mwamphamvu kwambiri, ingosinthani kusuntha kwa silinda pang'ono (sinthani zomangira zosinthira kugwedezeka kumapeto onse a silinda pang'ono nthawi imodzi, mukasintha, valavu iyenera kusunthidwa pamalo otseguka, kenako gwero la mpweya lizimitsidwe. Zimitsani kenako sinthani), sinthani mpaka valavu ikhale yosavuta kutsegula ndikutseka pamalo osatuluka. Ngati choletsa chimasintha, liwiro losinthira la valavu likhoza kusinthidwa. Ndikofunikira kusintha choletsa chitseko kuti chifike pamalo oyenera a liwiro losinthira valavu. Ngati kusintha kuli kochepa kwambiri, valavu singagwire ntchito.
