Kuti ma valve agwire ntchito, ziwalo zonse za ma valve zikhale zathunthu komanso zokhazikika. Ma bolts omwe ali pa flange ndi bracket ndi ofunikira kwambiri, ndipo ulusi uyenera kukhala wokhazikika ndipo palibe kumasuka komwe kumaloledwa. Ngati nati yomangirira pa handguard yapezeka kuti yamasuka, iyenera kumangidwa nthawi yake kuti ipewe kusweka kwa cholumikizira kapena kutayika kwa handguard ndi nameplate. Ngati handguard yatayika, siloledwa kuisintha ndi wrench yosinthika, ndipo iyenera kumalizidwa nthawi yake. Gland yonyamulira siloledwa kupotoka kapena kukhala ndi mpata womangika kale. Pa ma valve omwe ali pamalo omwe amaipitsidwa mosavuta ndi mvula, chipale chofewa, fumbi, mphepo ndi mchenga, tsinde la valvu liyenera kukhala ndi chivundikiro choteteza. Sikelo pa valvu iyenera kusungidwa bwino, yolondola komanso yowonekera bwino. Zisindikizo za lead, zipewa ndi zowonjezera za pneumatic za valvu ziyenera kukhala zathunthu komanso zokhazikika. Jekete loteteza siliyenera kukhala ndi mabowo kapena ming'alu.
Sizololedwa kugogoda, kuima kapena kuchirikiza zinthu zolemera pa valavu yomwe ikugwira ntchito; makamaka mavalavu osakhala achitsulo ndi mavalavu achitsulo choponyedwa ndi oletsedwa kwambiri.
Kusamalira ma valve osagwira ntchito
Kusamalira ma valve osagwira ntchito kuyenera kuchitika pamodzi ndi zida ndi mapaipi, ndipo ntchito yotsatirayi iyenera kuchitika:
1. Tsukanivalavu
Mphepete mwa valavu iyenera kutsukidwa ndi kutsukidwa popanda zotsalira ndi madzi, ndipo kunja kwa valavu kuyenera kupukutidwa bwino popanda dothi, mafuta,
2. Konzani magawo a valavu
Pambuyo poti valavu yasowa, kum'mawa sikungathe kusweka kuti kukhale kumadzulo, ndipo ziwalo za valavu ziyenera kukhala zokonzeka bwino kuti zipange malo abwino ogwiritsira ntchito kenako ndikuwonetsetsa kuti valavuyo ili bwino.
3. Chithandizo choletsa dzimbiri
Tulutsani chikwamacho mu bokosi lodzaza kuti mupewe kuwonongeka kwa galvanicvalavutsinde. Ikani mankhwala oletsa dzimbiri ndi mafuta pamwamba pa valavu yotsekera, tsinde la valavu, nati ya tsinde la valavu, pamwamba pa makina ndi zina malinga ndi momwe zinthu zilili; mbali zojambulidwa ziyenera kupakidwa utoto woletsa dzimbiri.
4. Chitetezo
Pofuna kupewa kukhudzidwa ndi zinthu zina, kugwira ndi kusokoneza zinthu zopangidwa ndi anthu, ngati kuli kofunikira, zigawo zosunthika za valavu ziyenera kukonzedwa, ndipo valavu iyenera kupakidwa ndi kutetezedwa.
5. kukonza nthawi zonse
Ma valve omwe akhala osagwira ntchito kwa nthawi yayitali ayenera kufufuzidwa ndikusamalidwa nthawi zonse kuti apewe dzimbiri ndi kuwonongeka kwa valavu. Kwa ma valve omwe akhala osagwira ntchito kwa nthawi yayitali, ayenera kugwiritsidwa ntchito atapambana mayeso a kuthamanga pamodzi ndi zida, zida, ndi mapaipi.
Kusamalira zipangizo zamagetsi
Ntchito yokonza chipangizo chamagetsi tsiku ndi tsiku nthawi zambiri imakhala yosachepera kamodzi pamwezi. Zomwe zili mkati mwake ndi izi:
1. Maonekedwe ake ndi oyera popanda fumbi lochuluka; chipangizocho sichinaipitsidwe ndi nthunzi, madzi ndi mafuta.
2. Chipangizo chamagetsi chili chotsekedwa bwino, ndipo malo aliwonse otsekera ndi malo aliwonse ayenera kukhala okwanira, olimba, olimba, komanso osatulutsa madzi.
3. Chipangizo chamagetsi chiyenera kupakidwa mafuta bwino, kupakidwa mafuta pa nthawi yake komanso ngati pakufunika, ndipo nati ya tsinde la valve iyenera kupakidwa mafuta.
4. Gawo lamagetsi liyenera kukhala bwino, ndipo pewani kuwonongeka kwa chinyezi ndi fumbi; ngati lili lonyowa, gwiritsani ntchito megohmmeter ya 500V kuti muyese kukana kwa insulation pakati pa zigawo zonse zonyamula magetsi ndi chipolopolo, ndipo mtengo wake usakhale wotsika kuposa o. Powumitsa.
5. Chosinthira chokha ndi chosinthira kutentha siziyenera kugwedezeka, kuwala kowonetsa kumawonekera bwino, ndipo palibe kulephera kwa kutayika kwa gawo, dera lalifupi kapena dera lotseguka.
6. Kagwiridwe ka ntchito ka chipangizo chamagetsi ndi kabwinobwino, ndipo kutsegula ndi kutseka kumakhala kosinthasintha.
Kusamalira zipangizo za pneumatic
Ntchito yokonza chipangizo cha pneumatic tsiku ndi tsiku nthawi zambiri imakhala yosachepera kamodzi pamwezi. Zinthu zazikulu zomwe zimagwiritsidwa ntchito pokonza ndi izi:
1. Maonekedwe ake ndi oyera popanda fumbi lochuluka; chipangizocho sichiyenera kuipitsidwa ndi nthunzi ya madzi, madzi ndi mafuta.
2. Kutseka chipangizo chopopera mpweya kuyenera kukhala bwino, ndipo malo otsekera ndi mfundo ziyenera kukhala zokwanira komanso zolimba, zolimba komanso zosawonongeka.
3. Njira yogwiritsira ntchito pamanja iyenera kukhala yothira mafuta bwino, yotseguka komanso yotseka mosavuta.
4. Malo olowera ndi otulutsira mpweya a silinda saloledwa kuwonongeka; zigawo zonse za silinda ndi mapaipi a mpweya ziyenera kuyang'aniridwa mosamala, ndipo pasakhale kutuluka kwa madzi komwe kungakhudze magwiridwe antchito.
5. Chitoliro sichiloledwa kumiza, chodziwitsira chiyenera kukhala bwino, kuwala kowunikira kwa chodziwitsira chiyenera kukhala bwino, ndipo ulusi wolumikizira wa chodziwitsira mpweya kapena chodziwitsira magetsi uyenera kukhala bwino popanda kutuluka madzi.
6. Ma valve omwe ali pa chipangizo chopopera mpweya ayenera kukhala abwino, opanda kutuluka madzi, otseguka mosavuta, komanso mpweya woyenda bwino.
7. Chipangizo chonse cha pneumatic chiyenera kukhala chogwira ntchito bwino, chotseguka komanso chotseka mosavuta.
Kukayikira kapena mafunso ambiri kwa okhala olimba mtimavalavu ya gulugufe, valavu ya chipata, mungathe kulankhulana ndiVavu ya TWS.
