Cholumikizira cha Rabara

1. Kodi cholumikizira cha rabara n'chiyani? Kodi ntchito yake ndi yotani mu mapaipi?

Ma raba, omwe amadziwikanso kuti ma raba ofewa ndi ma raba osinthasintha, ndi zinthu zolumikizira zosinthika zomwe zimayikidwa pakati pa ma valavu ndi mapaipi. Ntchito zake zazikulu zimaphatikizapo mfundo zinayi: kuchepetsa kugwedezeka ndi kuchepetsa phokoso - kuyamwa kugwedezeka ndi phokoso lamakina lomwe limapangidwa ndi ntchito ya mapampu amadzi, ma compressor ndi zida zina; kubwezeretsa kusuntha - kugaya kukulirakulira ndi kufupika kwa axial ndi kufupika kwa mapaipi chifukwa cha kukulirakulira ndi kufupika kwa kutentha; kuchepetsa kupanikizika - kuteteza ma valavu ndi mapaipi ku kuwonongeka ndi mphamvu zakunja; kusavuta kukhazikitsa - kulola cholakwika china chokhazikitsa ndikuchepetsa zofunikira za coaxiality ya mapaipi.

2. Kodi mitundu ikuluikulu ya zolumikizira za rabara ndi iti?

Pali mitundu itatu yodziwika bwino: dera limodzi (lomwe limagwira ntchito mosiyanasiyana, loyenera kuchepetsa kugwedezeka kwachizolowezi komanso kubweza kusamuka), monga momwe zasonyezedwera pa Chithunzi 01; dera lawiri (lowonjezera mphamvu, loyenera kusamuka kwakukulu), monga momwe zasonyezedwera pa Chithunzi 02; dera lochepetsera mphamvu (logwiritsidwa ntchito kulumikiza mapaipi a mainchesi osiyanasiyana), monga momwe zasonyezedwera pa Chithunzi 03, njira yolumikizira kumapeto imagawidwa m'magulu a flange (kulumikizana kwa bolt ndi flange ya valve) ndi mtundu wa clamp (kulumikizana mwachangu).

3. Kodi mungasankhe bwanji zinthu za rabara malinga ndi momwe zinthu zilili?

Rabala yachilengedwe ndi yoyenera kutentha kwabwinobwino monga madzi ndi mpweya; rabala ya nitrile ili ndi kukana mafuta bwino ndipo ndi yoyenera mapaipi okhala ndi mafuta ndi mafuta; rabala ya EPDM ndi yolimba ku ozoni, yolimba ku nyengo, yolimba ku asidi ndi alkali, ndipo imagwiritsidwa ntchito kwambiri m'mapaipi akunja ndi mankhwala; rabala ya fluorine/silicone imagwiritsidwa ntchito makamaka pa kutentha kwambiri (mpaka 200°C kapena kupitirira apo) kapena pazida zowononga kwambiri. Kusankha zinthu zolakwika kungapangitse kuti cholumikiziracho chitupa, chisweke kapena chifewere mwachangu.

4. Kodi ndi njira ziti zofunika kuzitsatira pokhazikitsa?

Choyamba:Kutalika kwa kuyika kuyenera kutsatira kutalika kwa chinthucho, ndipo kutambasula kapena kukanikiza kwambiri sikuloledwa (cholakwika chofala ndikutambasula dzenje mwamphamvu kuti liyikidwe, zomwe zimachepetsa kwambiri nthawi yogwirira ntchito);

Chachiwiri:Mabotolo ayenera kumangidwa mofanana mopingasa kuti apewe kuwonongeka pang'ono komwe kumachitika chifukwa cha kukondera;

Chachitatu:Mukayika pamalo otulukira madzi pa mpope, iyenera kuyikidwa kumbali ya pansi pa valavu kuti madzi asakhudze nyundo;

Chachinayi:ziyenera kusungidwa kutali ndi magwero a kutentha ndi magwero a ozone (monga ma mota ndi ntchito zowotcherera);

Chachisanu:Sizololedwa kugwiritsidwa ntchito m'mapaipi otayira mpweya. Pokhapokha ngati cholumikizira chapadera chotsutsana ndi waya wachitsulo chagwiritsidwa ntchito, mpirawo ukhoza kuphwanyika.

5. Kodi mungadziwe bwanji nthawi yomwe cholumikizira cha rabara chiyenera kusinthidwa?

Iyenera kusinthidwa nthawi yomweyo ngati pali chilichonse mwa izi: pali ming'alu yoonekeratu, thovu kapena mapindikidwe pamwamba; kutseka kwa flange pamwamba pa flange kumatuluka ndipo kumangika sikuthandiza; rabala imakhala yolimba ndipo imataya kusinthasintha (palibe chizindikiro cha kubwerera m'mbuyo ikakanikiza ndi chala); nthawi yogwira ntchito yomwe yalembedwa pa chinthucho imadutsa (nthawi zambiri zaka 5 mpaka 8). Ndikofunikira kuchita kuwunika nthawi zonse, makamaka m'malo ofunikira monga malo opopera madzi ndi madzi m'nyumba zazitali.

6. Mapeto

Malumikizidwe a rabara ndi omwe amachititsa kuti kulumikizana ndi chitetezo zikhale zosinthasintha, komansoTWSali ndi udindo wowongolera molondola komanso kuletsa kuyenda kwa madzi. Pokhapokha ngati ziwirizi zaphatikizidwa, dongosolo la mapaipi lidzakhala lathunthu komanso lodalirika. Mukasankha valavu, sankhaniTWS—mavavu a gulugufe, mavavu a chipatandima valve owunikira, zonse pamalo amodzi! Takulandirani kuti mutiyimbire foni kuti tikupatseni upangiri ndi kugula.
