1. Kusamalira ma valve
1.1 Zida zazikulu kwambiri:
Zambiri "DN: NPS1" ~ NPS28 "
PN: CL150 ~ CL2500
Zinthu zakuthupi: ASTM A216 WCB
Tsinde - ASTM A276 410; Mpando-ASTM A276 410;
Kusindikiza nkhope-VTION
1.2 Ntchito Manambala ndi Miyezo: API 6A, API 6D
1.3 Kapangidwe ka valavu (onani mkuyu 1)
Fanizo la 1 vavu wa pachipata
2. Kuyendera ndi kukonza
2.1: Kuyendera kwakunja:
Yenderani kumtunda kwa valavu kuti muwone ngati kulibe vuto, kenako nkuwerengedwa; Lembani.
2.2 Yang'anani chipolopolo ndikusindikiza:
Onetsetsani ngati pali vuto lililonse ndipo mulembe zowunika.
3. Disassemble wa valavu ndi
Valavu ayenera kutsekedwa pamaso disassemble ndi kumasula ndi akapichi kulumikiza. Adzasankha spanner yoyenera yosasinthika kuti ikhale yotsekemera, mtedza udzawonongeka mosavuta ndi spanner yosinthika.
Mabotolo ndi mtedza wadzimbiri ayenera kuthiridwa ndi palafini kapena chotsitsa dzimbiri; Onetsetsani ulusi wowongolera kenako ndikupotoza pang'onopang'ono. Magawo omwe adasungunuka amayenera kuwerengedwa, kusungidwa ndi kusungidwa bwino. Tsinde ndi chimbale chitseko ziyenera kuvala bulaketi kupewa zikande.
3.1 Kukonza
Onetsetsani kuti zida zotsalira zimatsukidwa pang'ono posakaniza ndi palafini, mafuta, kapena zida zoyeretsera.
Mukatha kuyeretsa, onetsetsani kuti zida zopumira sizipaka mafuta & dzimbiri.
3.2 Kuyendera zida zopumira.
Yenderani zida zonse zopumira ndikupanga mbiri.
Pangani dongosolo loyenera lokonzekera malinga ndi zotsatira zoyendera.
4. Kukonza zida zosinthira
Konzani zida zogwiritsira ntchito molingana ndi zotsatira zoyendera ndi kukonza; sinthanitsani zida zopumira ndi zida zomwezo ngati zingafunike.
Kukonzekera kwa chipata:
Kukonzanso kwa T-slot: Kuwotcherera kumatha kugwiritsidwa ntchito pokonza T-slot fracture, Konzani kupotoza kwa T-slot, Weld mbali zonse ndi bar yolimbikitsa. Kuwotcherera kotheka kumatha kugwiritsidwa ntchito kukonza pansi pa T-slot. Pogwiritsa ntchito chithandizo chakutentha mutawotcherera kuti muchepetse kupsinjika ndikugwiritsa ntchito kulowa kwa PT kuti muwone.
Kukonzanso kwagwetsedwa:
Kutayika kumatanthauza kusiyana kapena kusokonezeka kwakukulu pakati pa nkhope yosindikiza pachipata ndi nkhope yosindikiza ya Seat. Ngati yofanana vavu chipata waponya, akhoza china chotulutsa pamwamba ndi pansi mphero, ndiye, ndondomeko umapezeka.
Kukonzekera kwa nkhope yosindikiza
Zomwe zimayambitsa kutuluka kwamkati kwa valavu ndikusindikiza kuwonongeka kwa nkhope. Ngati kuwonongeka kuli kwakukulu, muyenera kuwotcherera, kusinthana ndi kugaya nkhope yosindikiza. Ngati sizovuta, kungopera. Kupera ndiyo njira yayikulu.
a. Mfundo yayikulu yopera:
Lowani pamwamba pa chida chopera pamodzi ndi chogwirira ntchito. Jekeseni wa abrasive gap pakati pa malowa, ndikusunthira chida chopera.
b. Kupera nkhope yosindikiza pachipata:
Njira zopera: magwiridwe antchito
Pakani abrasive pa mbale wogawana, ikani workpiece pa mbale, kenako mutembenuzire pogaya molunjika kapena "8" mzere.
4.3 Kukonza tsinde
a. Ngati pali zikande zilizonse pamtengo wosindikiza kapena pamtunda wosagwirizana sizingafanane ndi kapangidwe kake, nkhope yosindikiza idzakonzedwa. Njira kukonza: lathyathyathya umapezeka, zozungulira akupera, yopyapyala yopyapyala, makina akupera ndi phirilo akupera,
b. Ngati tsinde la valavu lakhotakhota> 3%, ndondomeko Yowongoka chithandizo ndi makina ochepera pang'ono kuti awonetsetse kuti akumaliza ndikuwunika. Njira zowongoka: Kusunthika kwapanikizika, Kuwongolera kozizira komanso kuwongola kwa kutentha.
c. Kukonza mutu wa tsinde
Tsinde mutu mbali mbali ya tsinde (tsinde dera, tsinde pamwamba, pamwamba mphero, kulumikiza ufa etc.) olumikizidwa ndi mbali zotseguka ndi zotseka. Njira kukonza: kudula, kuwotcherera, Ikani mphete, Ikani pulagi etc.
d. Ngati sangakwaniritse zofunikira pakuwunika, ayeneranso kupanga zokhala ndi zinthu zomwezo.
4.4 Ngati padzawonongeka ndi mawonekedwe a flange mbali zonse ziwiri za thupi, ayenera pokonza makina kuti agwirizane ndi zofunika muyezo.
4.5 Mbali zonse ziwiri za kulumikizana kwa thupi RJ, ngati sizingafanane ndi zofunikira pambuyo pakukonza, ziyenera kutsekedwa.
4.6 Kusintha kwa zovala
Kuvala ziwalo kumaphatikizapo gasket, kulongedza, O-mphete ndi zina. Konzani magawo atavala malinga ndi kukonzanso ndikupanga mbiri.
5. Sonkhanitsani ndikuyika
5.1 Kukonzekera: Konzani zida zopangira zokonzedwa, gasket, kulongedza, zida zowonjezera. Ikani ziwalo zonse mwadongosolo; osagona pansi.
5.2 Chitsulo chotsuka: Tsukani zida zosungira (zomangira, kusindikiza, tsinde, nati, thupi, boneti, goli ndi zina) ndi mafuta a palafini, mafuta kapena wothandizira. Onetsetsani kuti palibe mafuta & dzimbiri.
Kuyika 5.3:
Poyamba, yang'anani kutsetsereka kwa tsinde ndi chipata chosindikiza nkhope kutsimikizira kulumikizana;
Chotsani, pukutani thupi, boneti, chipata, kusindikiza nkhope kuti mukhale oyera, Ikani zida zina kuti mukhale omangika bwino.
