Kupopera mabomba amapangidwa kuti apange zipangizo zabwino

Kupopera mabomba amapangidwa kuti apange zipangizo za mafuta ndi zitsime za mafuta. Pothandizidwa ndi zipangizo zoterezi, chida chogwiritsira ntchito miyala chimachotsedwa ndipo chimatsikira mu dzenje, mpweya umatuluka, katundu (axial) amagwiritsidwa ntchito pa chida, ndipo kukanika kwa mpweya kapena kutsuka kumayikidwa mu nkhope. Zomwe amapanga zimagwiritsidwa ntchito motsatira ndondomeko za GOST No. 50278-92. Malingana ndi chizoloŵezi ichi, zinthuzo zimapangidwa ndi chitsulo, zimapangidwa mosasunthika ndipo zimabzala, zomwe zimamangiriza.

Dalapipes akhoza kukhala ndi mitundu yosiyanasiyana ya malo omwe anabzalidwa, kuphatikizapo: mkati, kunja komweko kapena kumodzi komwe kumatchedwa (MF, MN kapena PC). Zogulitsidwa za gulu la PV zimapangidwa ndi maina a kunja kwa mamita 73 mpaka 101.6 mm, kukula kwake kwa 8.4 mpaka 11.4 mm, kuwerengeka kwa mita imodzi ya phala yosalala kumachokera pa 14 mpaka 22 kg.

Ma diameter a mapepala a pulasitiki a PC afika pamtengo wotsika wa 139.7 mm (mtengo wochepa ndi 114.3 mm). Mipope yomwe imachokera kunja (PN) ili ndi pang "ono laling'ono laling'ono malinga ndi GOST (127 mm) yomwe ili pamwambayi. Kuwonjezera pa kutalika kwake, chifukwa cha mayina a mapaipi, mapaundi ofanana ndi mlingo wa loko (wopangidwa molingana ndi GOST 27 834) ndi kukula kwake kwa mgwirizano wodula, kuphatikizapo mkati mwake ndi m'mimba mwake pansi pa elevator, amalingaliridwa. Chinthu china chofunika kwambiri ndi kutalika, komwe kumaimiridwa ndi magulu atatu: kuchokera pa 5.9 mamita mpaka 6.3, kuchokera 8 mpaka 8.6 mamita ndi kuchokera 11.9 mpaka 12.5 mamita. Kukonzekera kwamakono kumachititsa kupanga mapaipi a kutalika ndi ang'onoang'ono kutalika, koma pakali pano sangathe kukwaniritsa miyezo yomwe ilipo.

Mipope yoyenerera yoyenerera iyenera kupangidwa kotero kuti pamtunda pawo panalibe ming'alu, mitolo, zipolopolo ndi zolakwika zina. Kukonza zolakwika zoterezi kungakhale pambali pa chitoliro, pamene kusindikiza, zachekanka ndi kutseketsa mavuto akuloledwa sizingaloledwe, iwo akhoza kutsukidwa kapena kudula.

Kupanga mapepala a kubowola kumapangidwira kotero kuti peresenti yaikulu ya phosphorous ndi sulfure pakasungunuka iliyonse imayang'aniridwa mosamala. Ngati bizinesi ikugwiritsa ntchito zipangizo zamtundu wina, ndiye kuti wopanga kampani amafuna zolemba potsatira khalidwe. Masiku ano, makampani ena amapanga mankhwala okhala ndi zophimba mkati (mwachitsanzo, TK-34R), zomwe zimathandiza kuteteza mapaipi kuti asawonongeke komanso kuvala, kutaya kutupa, kuchepetsa mpata wotopa, komanso kuwonongeka kwa magetsi panthawi ya kubowola. Chophimbacho chimagwiritsidwa ntchito mu ufa ndipo chimalola kuti chitoliro chipirire maola oposa 500 opaleshoni pa kutentha pamwamba pa 150 ° C, kuti apeze kutentha kosapitirira 8 J kutentha kwa 20 ° C,

Kupopera mapaipi amadziwika ngati zipangizo, zomwe nthawi zambiri zimaphwima chifukwa chovala madiresi (kunja, mpaka 60%). Mbali zina zotsala za chitoliro zikhale zoyenera kugwira ntchito. Posachedwapa, njira zowonjezera zitsulo zamagetsi zakhala zikugwiritsidwa ntchito kuthetsa vutoli. Izi zimapewa ming'alu yomwe imapangidwira mwapamwamba komanso zinthu zina zowononga kwambiri.
