Nthawi zambiri timanena kuti chitoliro chowonjezedwa chotentha chimatanthawuza chitoliro chachitsulo chokhala ndi kachulukidwe kakang'ono koma kuchepera kolimba, China National Standards Association imati chitoliro chachitsulo chowotcha chowonjezera chiyenera kukhala chitoliro chokulirapo chachitsulo chomwe chikukulitsidwa ndikupunduka pambuyo ponseponse. Kutentha kwa chitoliro chopanda kanthu chitsulo mapaipi amatha kupangidwa pogwiritsa ntchito mipope yokhazikika, ndipo mtengo wake ndi wotsika komanso magwiridwe antchito apamwamba. Ndi njira yodziwika bwino yopangira mapaipi opanda msoko. Chifukwa cha kukula kwakukulu kwa ma boiler opangira magetsi komanso kukula kwakukulu kwa zomera za petrochemical, kufunikira kwa mapaipi opanda msoko akulu akuchulukirachulukira, ndipo zimakhala zovuta kuti mayunitsi ogubuduza chitoliro apange chubu chopanda msoko chomwe chimakhala chachikulu kuposa 508mm, chiŵerengero cha m'mimba mwake ndi makulidwe a khoma (D/S)> 25, teknoloji yowonjezera kutentha, makamaka yotsika mtengo yapakati pafupipafupi yowonjezera kutentha kwapang'onopang'ono izo.

 

Chowonjezera chapaipi chowonjezera chamagulu awiri chomwe chimagwiritsidwa ntchito popanga mapaipi achitsulo owonjezera amaphatikiza ukadaulo wokulitsa ukadaulo wa cone die diameter, ukadaulo wapa digito wapakatikati wotenthetsera, komanso ukadaulo wa hydraulic mu makina amodzi. Ndi ndondomeko yake yololera, kugwiritsa ntchito mphamvu zochepa, ndalama zomangamanga zochepa, ndi zabwino The mankhwala khalidwe, osiyanasiyana zopangira ndi specifications mankhwala, kusinthasintha ndi otsika athandizira kupanga mtanda kusinthasintha alowa m'malo chikhalidwe kukoka-mtundu m'mimba mwake kukula luso la makampani zitsulo chitoliro. .

 

Tikumbukenso kuti mawotchi katundu otentha-wowonjezera zitsulo mipope zambiri zoipa pang'ono kuposa otentha adagulung'undisa zitsulo mapaipi.

 

Njira yowonjezereka yokulirapo kwa chitoliro ndikukonza chitoliro pa wononga zitsulo zotsogola, kuyika chotchingira chapamwamba chooneka ngati chulu chokhala ndi mainchesi akulu kuposa m'mimba mwake wa chitoliro kumapeto kwina kwa chitoliro, ndikulumikiza ndi kukonza chinacho. phula mu chitoliro. Kulumikizana pakati pa chitoliro ndi chowotcha chapamwamba kuli Pansi pa koyilo yapakatikati yotenthetsera, kuti muthane ndi kutentha kwambiri komanso kuphulika, muyenera kudutsa madzi mu chubu choyamba, yambitsani kutentha kwa koyilo, ndipo mutatha kufikira kutentha komwe kwatchulidwa. , chomangira chomwe chimalumikiza chubucho chimakankhira chubucho, kotero kuti chubucho chimasunthira kumtunda wapamwamba ndikufalikira. The top anvil taper imakulitsa kukula kwa chitoliro. Chitoliro chonsecho chikadutsa, chitolirocho sichidzakhala chowongoka chifukwa cha njira yowonjezera kutentha, choncho ayenera kuwongolera.

Zomwe zili pamwambazi ndizoyambira zamakono zamakono zowonjezera kutentha.

 Zotsatirazi ndi zoyenera chilinganizo cha matenthedwe kukod chitoliro

 

Kulemera kwake:

carbon steel: (kukhuthala kwa m'mimba mwake)× makulidwe× 0.02466 = kulemerat wa mita imodzi(kg)

aloyi: (diameter-thickness)× makulidwe× 0.02483 = kulemeramita imodzi (kg)

chiwerengero cha mamita pambuyo otentha kukodzedwa:

choyambirira chubu Diameter÷ otentha anawonjezera awiri× 1.04× kutalika *

 

machubu oyambira mita:

kutalika kwake× (diameter÷ choyambirira chubu awiri÷ 1.04)

 

liwiro:

100000÷ (kuchuluka kwake koyambirira× makulidwe)

 

makulidwe:

makulidwe owonjezera (nthawi imodzi) ) = makulidwe a chubu choyambirira× 0.92

Kukula kokulirapo (nthawi 2) = makulidwe a chubu choyambirira * 0.84

 

Diameter:

Kukula kwake = kukula kwa nkhungu + makulidwe okulirapo× 2

Kukula kwa nkhungu: kukula kwake-2 * kukulitsidwa makoma Makulidwe

 

Kulekerera kwa Diameter:

Diameter＜426mm, kulolerana±2.5

Mkati ndi kunja kwa zikande:

 

Kuzama kwakuya: 0.2mm, kutalika: 2cm, amatchedwa zikande. Zosaloledwa

Kuwongoka: ≤6 mita, kupindika ndi 5mm,≤12 mita, kupindika ndi 8mm

 

Mwachitsanzo:

Chubu choyambirira 610 * 19 chotentha chowonjezera 660 * 16

Kutalika kwa chitoliro choyambirira: 12.84meter

Kukula: 19 * 0.92 = 17.48 (1 nthawi)

19 * 0,84 = 15.96(2 nthawi）

Kutalika kwa chitoliro:610÷660*1.04*12.84=12.341962

M'mimba mwake: 625+17.48*2+1=660.96(nthawi imodzi)

625+15.96*2+1=657.92(2nthawi)

 

Kukula kwa gawo: 660-2 * 16 = 628
