Vavu yosindikiza pamwamba kuwonongeka chifukwa valavu Buku butterfly valavu

Kuwonongeka kwamakina, kusindikiza pamwamba pakutsegula ndi kutseka kwa US kudzatulutsa abrasion, kugunda, kufinya ndi kuwonongeka kwina. Pakati pa malo awiri osindikizira, pansi pa kutentha kwakukulu ndi kuthamanga kwapamwamba, maatomu amalowa mkati mwa wina ndi mzake, zomwe zimapangitsa kuti pakhale chodabwitsa. Pamene malo awiri osindikizira amasuntha wina ndi mzake, zomatira zimakoka mosavuta. Kusindikiza pamwamba pa roughness ndipamwamba, chodabwitsa ichi chimachitika mosavuta. Vavu mu njira yotseka, valavu chimbale pobwerera ku mpando adzapweteka ndi kufinya kusindikiza pamwamba, kuti kusindikiza pamwamba m'deralo kuvala kapena indentation.
Kukokoloka kwa sing'anga ndi chifukwa cha kuvala, kutsuka ndi cavitation ya kusindikiza pamwamba pamene sing'anga ikugwira ntchito. Pa liwiro linalake, tinthu tating'onoting'ono tating'onoting'ono timaphwanya kusindikiza pamwamba ndikupangitsa kuwonongeka kwanuko. Sing'anga yothamanga kwambiri idzatsuka mwachindunji malo osindikizira ndikupangitsa kuwonongeka kwanuko. Sing'anga ikasakanizidwa ndi kusungunuka pang'ono, thovu lokwiya limaphulika ndikukhudza malo osindikizira, zomwe zimapangitsa kuwonongeka kwanuko. Kusinthana kwa kukokoloka kwa media ndi kukokoloka kwa mankhwala kudzawononga kwambiri malo osindikizira.
Electrochemical kukokoloka, kusindikiza pamwamba kukhudzana wina ndi mzake, kusindikiza pamwamba ndi kutsekedwa thupi ndi valavu thupi kukhudzana ndi sing'anga ndende kusiyana, mpweya ndende kusiyana ndi zifukwa zina, adzabala lingathe kusiyana, electrochemical kukokoloka, chifukwa mu anode mbali ya kusindikiza pamwamba ndi kukokoloka. .
Chemical kukokoloka kwa sing'anga, sing'anga pafupi kusindikiza pamwamba pa nkhani ya palibe panopa, sing'anga mwachindunji amasewera mbali mankhwala ndi kusindikiza pamwamba, kukokoloka kusindikiza pamwamba.
Kuyika kosayenera ndi kusamalidwa bwino kumayambitsa ntchito yosadziwika bwino ya malo osindikizira, ndipo valavu imagwira ntchito ndi matenda, zomwe zimawononga malo osindikizira nthawi isanakwane.
Kuwonongeka kobwera chifukwa cha kusankha kosayenera ndi kuwongolera. Ntchito yaikulu ndi yakuti valavu simasankhidwa molingana ndi momwe ntchito ikugwirira ntchito, ndipo valavu yodulidwa imagwiritsidwa ntchito ngati valavu yowonongeka, yomwe imayambitsa kuthamanga kwapamwamba kwambiri komanso kuthamanga kwambiri kapena kutsekedwa kwachisawawa, kuti malo osindikizira awonongeke. ndi kuvala.
Kusindikiza pamwamba Machining khalidwe ndi zoipa, makamaka kusonyeza kusindikiza pamwamba zolakwika monga ming'alu, porosity ndi achepetsa mapangidwe, chifukwa cha kuwotcherera pamwamba ndi kutentha specifications mankhwala kusankha kosayenera mu ndondomeko ya pamwamba kuwotcherera ndi kutentha mankhwala ndi kulamulira, chifukwa cha nkhope yosindikiza yoyipa kwambiri kapena yotsika, chifukwa cha kusiyana komwe kumabwera chifukwa cha zolakwika kapena kutentha kosayenera, sankhani kulimba kwa zinthu zakuthupi, kulimba, kusakhala ndi dzimbiri, makamaka chifukwa poyang'ana pamwamba, chitsulo chapansi chimawombera pamwamba, kuchepetsa kusindikiza. pamwamba aloyi zikuchokera chifukwa. Inde, palinso nkhani za mapangidwe.
Zomwe zimayambitsa kuwonongeka kosindikiza pamwamba zitha kufotokozedwa mwachidule motere.
Chifukwa cha kusindikiza kuwononga pamwamba ndi kuwonongeka kwa anthu ndi kuwonongeka kwa chilengedwe. Kuwonongeka kochita kupanga kumachitika chifukwa cha zinthu monga kusapanga bwino, kupanga kosapanga bwino, kusankha zinthu molakwika, kuyika molakwika, kusagwiritsa ntchito bwino komanso kusamalidwa bwino. Kuwonongeka kwachilengedwe ndikuwonongeka kwa valavu pansi pazikhalidwe zogwirira ntchito, komanso kuwonongeka komwe kumachitika chifukwa cha kukokoloka kosalephereka ndi kukokoloka kwa malo osindikizira ndi sing'anga.
Valavu ya butterfly Imayendetsedwa ndi chogwirira kapena chida chotumizira magiya, valavu yagulugufe yamagetsi kapena pneumatic imayendetsedwa ndi chipangizo chamagetsi kapena chipangizo cha pneumatic, kotero kuti mbale yagulugufe imazungulira 90 ° kuti itsegule kapena kutseka valavu. Kwa mavavu agulugufe omwe amagwira ntchito pamanja (kuphatikiza gudumu la m'manja la chipangizo choyendetsera) kapena ndi wrench, valavu iyenera kutsekedwa potembenuza gudumu lamanja kapena wrench molunjika poyang'ana pa handwheel kapena wrench, pokhapokha atanenedwa mwanjira ina. Vavu iyenera kusungidwa m'chipinda chouma, cholowera mpweya. Mapeto onse awiri a ma valve ayenera kutsekedwa. Mavavu osungidwa kwa nthawi yayitali amayenera kuyang'aniridwa pafupipafupi ngati ali ndi dothi. Chisamaliro chapadera chiyenera kuperekedwa pakuyeretsa kwa malo osindikizira kuti ateteze kuwonongeka kwa malo osindikizira.

4.3 Malangizo otsegula ndi kutseka a ma valve agulugufe amagetsi ndi pneumatic amadziwika ndi zizindikiro za malo pazida zamagetsi ndi pneumatic.
5. Kusungirako, kukonza, kukhazikitsa ndi kugwiritsa ntchito
5.1 Vavu iyenera kusungidwa m'chipinda chowuma ndi mpweya wabwino, ndipo mapeto onse a valve ndi otsekedwa.
5.2 Mavavu osungidwa kwa nthawi yayitali ayenera kuyang'aniridwa nthawi zonse ngati ali ndi dothi. Chisamaliro chapadera chiyenera kuperekedwa pakuyeretsa kwa malo osindikizira kuti ateteze kuwonongeka kwa malo osindikizira.
5.3 Musanayambe kukhazikitsa, fufuzani mosamala ngati chizindikiro cha valve chikugwirizana ndi zofunikira zogwiritsira ntchito.
5.4 Musanakhazikitse, ndime ya valve ndi malo osindikizira ayenera kufufuzidwa. Ngati pali zonyansa, ziyenera kutsukidwa ndi nsalu yoyeretsera.
5.5 Musanakhazikitse, fufuzani ngati kulongedza kumaponderezedwa kuti zitsimikizidwe kuti kulongedza ndi mpweya ndipo sayenera kulepheretsa kuzungulira kwa tsinde la valve.
5.6 Pakuyika, mphamvu yolimba ya cholumikizira wononga iyenera kutsekedwa mofanana.
5.7 Vavu yagulugufe imatha kuyikidwa pamapaipi opingasa ndi ofukula, ndipo malo oyikapo ayenera kuwonetsetsa kuti ndiyosavuta kugwiritsa ntchito, kukonza ndikusintha.
5.8 Pamene valve yamanja imatsegulidwa kapena kutsekedwa, chogwiriracho chiyenera kugwiritsidwa ntchito potsegula ndi kutseka, ndipo chothandizira chothandizira kapena zida zina siziyenera kubwereka.
5.9 Valavu iyenera kuyang'aniridwa pafupipafupi kuti iwonongeke komanso kuyika gasket pamalo osindikizira. Pakawonongeka kapena kulephera, konzani kapena kusintha munthawi yake.
5.10 Kusungirako, kukonza, kukhazikitsa ndi kugwiritsa ntchito zipangizo zamagetsi zamagetsi ndi pneumatic valve transmission, chonde onani "Malangizo ogwiritsira ntchito zipangizo zamagetsi zamagetsi" ndi "Malangizo Ogwiritsira Ntchito Zida Zopangira Pneumatic valve".
6. Zolakwika zomwe zingatheke, zomwe zimayambitsa, ndi njira zochotsera zikuwonetsedwa mu Gulu 1
Table 1 Zolakwika zomwe zingatheke, zomwe zimayambitsa, ndi njira zothetsera mavuto
Chitsimikizo cha 7.
Wopanga ali ndi udindo wotsimikizira za valve mkati mwa chaka chimodzi atagwiritsidwa ntchito, koma osapitirira miyezi 18 atabereka. Mkati mwa chitsimikizo nthawi, chifukwa cha zifukwa khalidwe mankhwala akhoza anakonza kapena m'malo mbali.
