Kushanda uye Kugadzirisa Manual-Cast Steel Gate Mavhavha

3. Kuchengetedza, kuchengetedza, Kuisa uye kushanda

3.1 Kuchengeta uye kugadzirisa
3.1.1 Mavharuvhu anofanira kuchengetwa muimba yakaoma uye ine mhepo yakanaka.Iyo ndima inopera inofanira kubatanidzwa nemavhavha.
3.1.2 Mavhavha pasi pekuchengetedza kwenguva refu anofanirwa kuongororwa uye kucheneswa nguva dzose, kunyanya kucheneswa kwechiso chekugara kudzivirira kukanganisa, uye nzvimbo dzakapedzwa dzinofanira kuputirwa nehutu inodzivisa mafuta.
3.1.3 Kana nguva yekuchengetedza ichipfuura mwedzi ye18, mavharuvhu anofanira kuongororwa uye zvinyorwa zvinofanira kuitwa.
3.1.4 Mavharuvhu akaiswa anofanira kuongororwa uye kugadziriswa nguva dzose.Nzvimbo huru dzekuchengetedza dzinosanganisira zvinotevera:
1)Kuisa chisimbiso chiso
2)Vhunde yevharuvhu uye vharafu stem nati.
3)Kurongedza.
4) Kusvibisa mukati memukati wemuviri wevharuvhu uye bhoneti yevharuvhu
3.2 Kuiswa
Usati waiswa, ita chokwadi chekuzivikanwa kwevharuvhu (senge modhi, DN, 3.2.1PN uye zvinhu) zvakamisikidzwa zvinoenderana nezvinodiwa nepombi system.
3.2.2 Usati waiswa, nyatso tarisa muvharo wevharuvhu uye chisimbiso chechiso.Kana pane tsvina, ichenese zvakakwana.
3.2.3 Usati waiswa, ita shuwa kuti mabhaudhi ese akasungwa zvakasimba.
3.2.4 Usati waisa, ita shuwa kuti kurongedza kwakatsikirirwa zvakasimba.Zvisinei, kufamba kwevhavha stem hakufaniri kukanganiswa.
3.2.5 Nzvimbo yekuisa yevhavha inofanira kufambisa kuongorora nekushanda.Nzvimbo inodiwa inofanira kunge iri yekuti pombi yakachinjika, vhiri reruoko riri pamusoro, uye hunde yevharuvhu yakamira.
3.2.6 Pavharuvhu yakavharwa, haina kukodzera kuiisa panzvimbo ine simba rekushanda rakakura kwazvo kudzivirira kukuvara kwehunde yevharuvhu.
3.2.7 Socket welded mavharuvhu anofanira kunge azadzisa zvinotevera zvinodikanwa kana aiswa welded kuti agadzirwe papipeline system panzvimbo:
1) Welding inofanirwa kuitiswa nemucheri ane chitupa chekuweder chinotenderwa neHurumende Boiler uye Pressure Vessel Authority;kana welder awana chitupa chemugadziriso chakataurwa muASME Vol.Ⅸ.
2) Welding process parameters inofanirwa kusarudzwa sezvakatsanangurwa mumhando yekusimbisa bhuku rewelding zvinhu.
3) Kuumbwa kwekemikari, mashandiro emuchina uye kushorwa kwesimbi yekuzadza simbi yewelding seam inofanirwa kuenderana ne base simbi.
3.2.8 Ivhavha inowanzoiswa, kushungurudzika kukuru nekuda kwezvitsigiro, zvishandiso uye mapaipi zvinofanira kudziviswa.
3.2.9 Mushure mekuisa, panguva yekuedzwa kwekumanikidza kwepipeline system, valve inofanira kuvhurwa zvizere.
3.2.10 Poindi yekutakurisa: kana pombi iine simba rakakwana kutakura huremu hwevharuvhu uye torque yekushandisa, saka hapana poindi inotakura inodiwa, zvikasadaro vharafu inofanira kunge iine poindi yekuberekera.
3.2.11 Kusimudza: usashandise vhiri remaoko kusimudza nekusimudza vharafu.
3.3 Kushanda uye kushandiswa
3.3.1 Munguva yebasa, gedhi revharuvhu rinofanira kuvhurwa zvakazara kana kuvharwa zvakazara kudzivirira kukuvara kwepamusoro pechigaro chechigaro uye gedhi revharuvhu nekuda kwekumhanya-mhanya.Haikwanise kushandiswa kugadzirisa kuyerera kwehuwandu.
3.3.2 Paunenge uchivhura kana kuvhara vharafu, shandisa handwheel pane yekubatsira lever kana kushandisa chimwe chishandiso.
3.3.3 Pakushanda tembiricha, ita chokwadi chekukurumidza kudzvanywa kwadzikira pane 1.1nguva iyo inoshanda yekumanikidza-tembiricha zviyero muASME B16.34.
3.3.4 Midziyo yekuyamura yekuchengetedza inofanira kuiswa papombi kudzivirira kushanda kwevharuvhu patembiricha yekushanda kubva pakupfuura kudzvinyirira kunobvumirwa.
3.3.5 Kurova uye kuvhundutsa valve kunorambidzwa panguva yekufambisa, kuisa uye kushanda nguva.
3.3.6 Kuparara kwemvura isina kugadzikana, semuenzaniso, kuparara kweimwe mvura kunogona kukonzera kuwedzera kwehuwandu uye kutungamirira kushanda kwekumanikidza kukwira, nokudaro kukuvadza valve uye kukonzera kupera, saka, shandisa midziyo yekuyera yakakodzera kubvisa kana kuderedza zvinhu zvinogona kukonzera kuora. yemvura.
3.3.7 Kana mvura yacho iri condensate, izvi zvinokanganisa kushanda kwevharuvhu, shandisa midziyo yekuyeresa yakakodzera kuderedza tembiricha yemvura (somuenzaniso, kuvimbisa tembiricha yakakodzera yemvura) kana kuitsiva neimwe mhando yevharuvhu.
3.3.8 Pamvura inozvipisa yega, shandisa midziyo yekuyeresa yakakodzera kuvimbisa ambient uye kushanda nesimba kusapfuudza nzvimbo yayo yekuzvibatisa (kunyanya cherechedza kupenya kwezuva kana moto wekunze).
3.3.9 Kana paine mvura ine njodzi, seinoputika, inopisa.Toxic, oxidation zvigadzirwa, zvinorambidzwa kutsiva kurongedza pasi pekumanikidzwa (kunyangwe vharafu ine basa rakadaro).
3.3.10 Iva nechokwadi chokuti mvura haina kusvibiswa, iyo inokanganisa kushanda kwevhavha, haina kuoma kwakaoma, kana zvisina kudaro midziyo yekuyera yakakodzera inofanira kushandiswa kubvisa tsvina uye yakaoma yakaoma, kana kuitsiva nemamwe marudzi evhavha.

3.3.11 Tembiricha inobvumirwa kushanda:
