Njira zodzitetezera ndi ziti pambuyo pakuchulukirachulukira kwavalavuchoyatsira magetsi?

Njira yochepetsera ma valve
Choyamba, kuyeretsa masitepe
Zigawo za valve ziyenera kudutsa njira zotsatirazi musanayike:
1, malinga ndi zofunika processing, mbali zina ayenera kuchita kupukuta mankhwala, pamwamba sangakhale ndi processing burr, etc.;
2. Ziwalo zonse zadetsedwa;
3, pickling passivation pambuyo degreasing, kuyeretsa wothandizila lilibe phosphorous;
4, pambuyo pickling passivation, nadzatsuka ndi madzi oyera, palibe mankhwala zotsalira, mpweya zitsulo mbali sanatchule sitepe iyi;
5, mbali imodzi ndi sanali nsalu nsalu youma, sangathe kusunga waya mbali ubweya pamwamba, kapena woyera nayitrogeni youma;
6. Pukutani zigawozo chimodzi ndi chimodzi ndi nsalu zosalukidwa kapena pepala la sefa yolondola yodetsedwa ndi mowa weniweni mpaka palibe mtundu wakuda.
Chachiwiri, zofunika pa msonkhano
Zigawo zoyeretsedwa ziyenera kusindikizidwa kuti zikhazikitsidwe. Zofunikira pakukhazikitsa ndi izi:
1. Malo ochitirako unsembe ayenera kukhala aukhondo, kapena akhazikitse malo aukhondo kwakanthawi, monga nsalu zamitundumitundu zomwe zagulidwa kumene kapena filimu ya pulasitiki, kuti fumbi lisalowe poikapo.
2, ogwira ntchito pamsonkhano ayenera kuvala zovala zoyera za thonje, kuvala chipewa choyera cha thonje, tsitsi silingadutse, mapazi amavala nsapato zoyera, manja amavala magolovesi apulasitiki, degreasing.
3. Zida zochitira msonkhano ziyenera kuchotsedwa ndi kutsukidwa musanasonkhene kuti zitsimikizire zaukhondo
Zofunikira zina
1. Tsukani valavu yophatikizidwa ndi nayitrogeni kwa mphindi imodzi.
2, kuyezetsa kopanda mpweya kuyenera kukhala koyera nayitrogeni.
3. Mukadutsa mayeso oletsa mpweya, pangani ndikusindikiza ndi kapu yoyera ya polyethylene. Musanagwiritse ntchito kapu ya polyethylene, zilowerereni ndi zosungunulira za organic ndikupukuta.
4. Kenako sindikizani ndi thumba la vacuum.
5. Pambuyo ponyamula katundu.
6. Njira ziyenera kuchitidwa kuti zitsimikizire kuti phukusi silikuwonongeka panthawi yoyendetsa.
Iv. Zofuna kuvomereza
Kuvomerezedwa kudzatsatira HG 20202-2000 "Code for Construction and Acceptance of Degreasing Engineering". Musanasonkhane, gawo lililonse lipukutidwe ndi pepala loyera bwino bwino.
Kodi njira zodzitetezera ndi ziti pambuyo podzaza ma valve oyendetsa magetsi?
Vavu, monga chinthu chofunikira pamakina othandizira, imakhudza mbali zonse za moyo wa anthu, ndi kuchuluka kwa msika wa ma valve, makampani opanga ma valve m'malo ofunikira kwambiri, ilinso ndi chiyembekezo chabwino kwambiri cha chitukuko. Choncho, mwayi kutsogolo kwa msika valavu pafupifupi anapanga mankhwala khalidwe chitetezo ndi mpikisano mankhwala mtundu, aliyense valavu ogwira ntchito kufunafuna mankhwala adzakhala apamwamba chatekinoloje, magawo mkulu, amphamvu dzimbiri kukana, moyo wautali malangizo.
Valve electric actuator ndi chida chofunikira kwambiri kuti muzindikire kuwongolera pulogalamu ya valve, kuwongolera zokha komanso kuwongolera kutali. Kusuntha kwake kumatha kuyendetsedwa ndi stroke, torque kapena axial thrust. Popanga, mota siyimagwiritsidwa ntchito, izi siziloledwa kuchitika. Ngati pali chodabwitsa chotere, ndikofunikira kudziwa chomwe chimayambitsa, zomwe zimatsogolera ku zifukwa zotsatirazi za katundu:
1, magetsi ndi otsika, sangathe kupeza makokedwe ofunikira, kotero kuti mota imasiya kuzungulira;
2, molakwika ikani njira yochepetsera ma torque, kuti ikhale yayikulu kuposa torque yoyimitsidwa, zomwe zimapangitsa kuti ma torque apitirire mopitilira muyeso, kotero kuti mota imasiya kuzungulira;
3, pakagwiritsidwe ntchito, kupulumutsa kutentha, kuposa kutentha kovomerezeka kwagalimoto;
4. Pazifukwa zina, njira yochepetsera ma torque imalephera ndipo torque ndi yayikulu kwambiri;
5, kugwiritsa ntchito kutentha kozungulira ndikokwera kwambiri, kumachepetsa mphamvu yamoto.
Njira zodzitetezera zochulukirachulukira:
1, ntchito yosalekeza yagalimoto kapena ntchito yoteteza katundu wambiri, pogwiritsa ntchito thermostat;
2, chitetezo chamoto chotchinga, pogwiritsa ntchito matenthedwe opatsirana;
3, pangozi yaifupi yozungulira, gwiritsani ntchito fuse kapena relay overcurrent.
Valve electric actuator ndi chida chofunikira kwambiri kuti muzindikire kuwongolera pulogalamu ya valve, kuwongolera zokha komanso kuwongolera kutali. Njira yake yoyenda imatha kuyendetsedwa ndi sitiroko, torque kapena axial thrust. Kusankha kolondola kwa chipangizo chamagetsi cha valve ndikofunikira kwambiri kuti tipewe kuchulukirachulukira (makokedwe ogwirira ntchito apamwamba kuposa torque yowongolera). Kuyika kolakwika kwa magawo a dongosolo lowongolera kumayambitsa kugwedezeka kwa dongosolo lowongolera. Ngati kupindula molingana ndi chowongolera chimodzi ndi chachikulu kwambiri, nthawi yophatikizika ndi yaifupi kwambiri, ndipo nthawi yosiyana ndi kupindula kosiyana ndi yayikulu kwambiri, zitha kuchititsa kuti dongosololi lidutse, ndikupangitsa kuti actuator oscillation. Kwa machitidwe olamulira amitundu yambiri, kuwonjezera pazifukwa zomwe zili pamwambazi, palinso vuto la kugwirizana pakati pa malupu, vuto la resonance chifukwa cha kukhazikitsidwa kosayenera kwa parameter. Poganizira mavuto omwe alipo, magawowa akhoza kusinthidwanso kuti apangitse kuzungulira kwa ulamuliro kukhala ndi malire okhazikika popanda kukhudza kupanga komanso mogwirizana ndi zofunikira zoyendetsera ndondomeko.
