Kufunika Kwa Mapaipi Owotcherera Pawiri ndi Mapaipi Opangidwa ndi Polyurethane mu Kuwotcherera Mapaipi

Kufunika Kwa Mapaipi Owotcherera Pawiri ndi Mapaipi Amizere A Polyurethane mu Kuwotcherera Mapaipi Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Pankhani ya kuwotcherera chitoliro, kugwiritsa ntchito mapaipi owotcherera pawiri ndi mapaipi okhala ndi polyurethane amathandizira kwambiri kuwonetsetsa kuti payipiyo ndi yodalirika komanso yodalirika.Zigawo ziwirizi ndizofunikira kwambiri kuti pakhale kukhulupirika kwa mapaipi, makamaka pazovuta zamafakitale pomwe mapaipi amatha kupanikizika kwambiri, kuwononga zinthu komanso kutentha kwambiri.

Chitoliro chowirikiza kawiriamatanthauza chitoliro chomwe chawotcherera pawiri kuti apange cholumikizira champhamvu, cholimba.Chitoliro chamtunduwu chimagwiritsidwa ntchito kwambiri pomanga mapaipi pomwe kuwotcherera kwabwino ndi mphamvu ndizofunikira.Njira yowotcherera pawiri imaphatikizapo kugwiritsa ntchito njira zowotcherera kuti muphatikize mapaipi awiri osiyana kuti atsimikizire kulumikizana kolimba komanso kopanda msoko.Sikuti izi zimangowonjezera mphamvu zonse ndi kulimba kwa chitoliro, zimachepetsanso chiopsezo cha kuwotcherera zolakwika ndi kutayikira komwe kungatheke.

Polyurethane chitoliro chokhazikika, kumbali ina, ndi chitoliro chokhala ndi zokutira za polyurethane zomwe zimapereka chitetezo chowonjezera ku dzimbiri, kuphulika, ndi kuukira kwa mankhwala.Mzerewu umagwiritsidwa ntchito mkati mwa chitoliro kuti apange chotchinga pakati pa madzi omwe amanyamulidwa ndi zitsulo pamwamba pa chitoliro.Mapaipi okhala ndi mizere ya polyurethane ndiwothandiza makamaka pamapaipi omwe amagwiritsidwa ntchito kunyamula zinthu zowononga kapena kugwira ntchito m'malo ovuta.Zingwe za polyurethane sizimangowonjezera moyo wa mapaipi anu, zimachepetsanso chiwopsezo cha kutayikira komanso mtengo wokonza.

Komanso, kupanga dzuwa lamipope yachitsulo yozungulirandi apamwamba kwambiri kuposa mapaipi achitsulo opanda msoko.Kwa chitoliro chopanda msoko, ntchito yopanga imaphatikizapo kutulutsa billet yolimba yachitsulo kudzera mu ndodo ya perforated, zomwe zimapangitsa kuti pakhale njira yochepetsetsa komanso yovuta kwambiri.Mosiyana ndi izi, chitoliro chopangidwa ndi spiral welded chimatha kupangidwa mokulirapo komanso kutalika kwake, zomwe zimapangitsa kuti nthawi yopanga ikhale yocheperako komanso kuti ichuluke.Izi zimatsimikizira kuperekedwa kosasinthasintha kwa mapaipi apamwamba kwambiri munthawi yochepa, ndikupangitsa kukhala njira yodalirika komanso yopulumutsira nthawi yamafakitale osiyanasiyana.

Ubwino wina wodziwika bwino wa mipope yowotcherera yozungulira ndi kukana kwawo kukakamiza kwakunja komanso kupsinjika kwamakina.Ma welds amapereka kulimba kwina, kulola mipope iyi kupirira kupsinjika kwakukulu kuposa mapaipi opanda msoko.Katunduyu ndi wofunikira kwambiri pakugwiritsa ntchito makampani amafuta ndi gasi, pomwe mapaipi amakumana ndi zovuta zamkati ndi zakunja.Pogwiritsa ntchito mipope yozungulira yozungulira, makampani amatha kuonetsetsa kuti zinthu zofunikazi zikuyenda bwino komanso motetezeka.

Mu kuwotcherera chitoliro, kuphatikiza chitoliro chowotcherera pawiri ndi chitoliro cha polyurethane chili ndi zabwino zambiri.Choyamba, kugwiritsa ntchito chitoliro chowotcherera kawiri kumatsimikizira kukhulupirika kwa chitoliro, kuchepetsa kuthekera kwa zolakwika zowotcherera ndi kulephera kotsatira.Izi ndizofunikira makamaka m'mafakitale omwe mapaipi amatha kupanikizika kwambiri komanso kusinthasintha kwa kutentha.Kuphatikiza apo, kugwiritsa ntchito mapaipi okhala ndi mizere ya polyurethane kumapereka chitetezo chowonjezera ku dzimbiri ndi kuvala, kukulitsa kulimba kwa chitoliro ndi moyo wautali.

Kuphatikiza apo, kugwiritsa ntchito chitoliro chowotcherera pawiri ndi chitoliro chokhala ndi polyurethane kumatha kupulumutsa ndalama kwa ogwiritsa ntchito mapaipi.The kumatheka mphamvu ndi durability wa pawiri welded chitoliro akhoza kuchepetsa kufunika kukonzanso pafupipafupi ndi kukonza, kupulumutsa nthawi ndi ndalama mu nthawi yaitali.Momwemonso, zokutira zoteteza zomwe zimaperekedwa ndi chitoliro chokhala ndi polyurethane zimatha kuwonjezera moyo wautumiki wa chitoliro, potero kuchepetsa ndalama zosinthira ndi kukonza.

Pomaliza, kugwiritsa ntchito mapaipi owotcherera pawiri ndi mapaipi okhala ndi polyurethane ndikofunikira pakuwotcherera mapaipi.Zigawozi sizimangotsimikizira kukhulupirika kwapangidwe ndi mphamvu ya payipi, komanso zimapereka chitetezo chofunikira ku dzimbiri, abrasion ndi kuukira kwa mankhwala.Mwa kuphatikiza matekinoloje apamwambawa pakumanga mapaipi, ogwira ntchito amatha kukwaniritsa zodalirika, zogwira ntchito komanso zotsika mtengo zamapaipi awo.
