Mgwirizano Wokulitsa Mpira

Mgwirizano wokulitsa mphira, yomwe imadziwikanso kuti chophatikizira cha mphira, ndi njira yolumikizirana yowonjezera

1. Nthawi zofunsira:

Mgwirizano wokulitsa mphira ndi kuphatikiza kosinthika kwa mapaipi achitsulo, omwe amapangidwa ndi gawo la mphira lolimbikitsidwa ndi wosanjikiza wamkati wa mphira, nsalu ya chingwe cha nayiloni, wosanjikiza wakunja wa mphira ndi flange yachitsulo yotayirira.Ili ndi mawonekedwe a kukana kuthamanga kwambiri, kukhazikika bwino, kusamuka kwakukulu, kupatuka kwapaipi moyenera, kuyamwa kwa vibration, zotsatira zabwino zochepetsera phokoso ndikuyika kosavuta;Itha kugwiritsidwa ntchito kwambiri popereka madzi ndi ngalande, madzi ozungulira, HVAC, chitetezo chamoto, kupanga mapepala, mankhwala, petrochemical, sitima, mpope wamadzi, kompresa, zimakupiza ndi machitidwe ena mapaipi.

2.Momwe mungasungire mgwirizano wokulitsa mphira:

Sing'anga yake yotumizira imatsimikizira moyo wa mgwirizano wokulitsa mphira.Zidulo zowononga, maziko, mafuta ndi mankhwala zimakhudzana ndi ufa mu olimba, chitsulo ndi nthunzi mu gasi.Zitha kugwiritsidwa ntchito kusintha zinthu kuti ziwongolere zofalitsa zosiyanasiyana zopatsirana, zomwe ndikusunga valavu ndi zovuta zakuthupi.Kuyika mavuto Pakuyika, malo oyikapo adzawonekera padzuwa, zomwe zidzawononge mphira ndi zaka, choncho m'pofunika kuphimba pulojekiti yowonjezera mphira ndi filimu ya dzuwa.Pankhani ya kuyika, mgwirizano wokulitsa mphira wokhawokha umakhala ndi malo okwera kwambiri, ndipo kufunikira kokakamiza kumakhala kwakukulu, kotero kuti mgwirizano wowonjezera mphira ukhoza kuikidwa panthawiyi.Njira ziwirizi zimagwiritsanso ntchito mphamvu zakunja kuti zisunge mgwirizano wokulitsa mphira.Panthawi yogwira ntchito, pamene mphira yowonjezera yowonjezera ikugwiritsidwa ntchito, m'pofunika kuyang'anitsitsa nthawi zonse kulimba kwa bawuti ya gawo loyikapo gawo lokulitsa labala.Ngati zikugwiritsidwa ntchito kwa nthawi yayitali, zomangirazo zimachita dzimbiri ndikusweka, kotero ziyenera kusinthidwa.Njira yokonza iyi ndi ya m'malo mwa tizigawo tating'ono, zomwe zimatha kukhalabe ndi zigawo zazikulu.

3. Njira yoyika:

Chitsanzo, ndondomeko ndi makonzedwe a mapaipi a mgwirizano wokulitsa ayenera kufufuzidwa asanakhazikitsidwe kuti atsimikizire kuti akukwaniritsa zofunikira za mapangidwe.Pamalo olumikizirana ndi manja amkati, ziyenera kuzindikirika kuti komwe kolowera mkati kuzikhala kogwirizana ndi komwe kumayendera sing'anga, ndipo ndege yozungulira ya hinge yolumikizira mtundu wa hinge ikugwirizana ndi ndege yozungulira.Kwa compensator yomwe imafuna "kumizidwa kozizira", zida zothandizira zomwe zimagwiritsidwa ntchito popanga deformation sizidzachotsedwa mpaka payipi itayikidwa.Ndi zoletsedwa kusintha unsembe chifukwa kulolerana payipi ndi mapindikidwe a malata kukula olowa, kuti asakhudze ntchito yachibadwa ya compensator, kuchepetsa moyo utumiki ndi kuonjezera katundu wa payipi dongosolo, zipangizo ndi othandizira mamembala. .Pa unsembe, kuwotcherera slag sikuloledwa kuwaza pamwamba pa yoweyula mlandu, ndi yoweyula mlandu saloledwa kuvutika ndi kuwonongeka mawotchi ena.Dongosolo la chitoliro litayikidwa, zida zothandizira ndi zomangira zomwe zimagwiritsidwa ntchito pakuyika ndi kunyamula pagawo lokulitsa lamalata zidzachotsedwa posachedwa, ndipo chida choyikiracho chidzasinthidwa ku malo omwe adanenedwa malinga ndi zofunikira za kapangidwe kake. dongosolo la chitoliro lili ndi mphamvu zokwanira zolipirira pansi pa zochitika zachilengedwe.Zinthu zosunthika za mgwirizano wokulitsa sizidzatsekedwa kapena kuletsedwa ndi zigawo zakunja, ndipo ntchito yachibadwa ya gawo lililonse losunthika lidzatsimikiziridwa.Pakuyezetsa kwa hydrostatic, chithandizo chachiwiri chokhazikika cha chitoliro chokhala ndi kumapeto kwa chitoliro cholumikizira chiwonjezedwe chidzalimbikitsidwa kuti chitoliro chisasunthe kapena kuzungulira.Kwa compensator ndi payipi yake yolumikizira yomwe imagwiritsidwa ntchito popanga gasi, samalani ngati kuli kofunikira kuwonjezera thandizo kwakanthawi podzaza madzi.Ma 96 ion omwe ali mu njira yoyeretsera yomwe amagwiritsidwa ntchito poyesa hydrostatic sayenera kupitirira 25PPM.Pambuyo pakuyesa kwa hydrostatic, madzi osonkhanitsidwa mu chipolopolo cha mafunde adzakhetsedwa posachedwa ndipo mkati mwa chipolopolo cha mafundewo amawumitsidwa.

4.Makhalidwe a gulu lokulitsa labala:

Zolumikizira zowonjezera mphira zimagwiritsidwa ntchito kutsogolo ndi kumbuyo kwa mpope wamadzi (chifukwa cha kugwedezeka);Chifukwa cha zipangizo zosiyanasiyana, mphira akhoza kukwaniritsa zotsatira za asidi ndi kukana zamchere, koma ntchito kutentha zambiri m'munsimu 160 ℃, makamaka mpaka 300 ℃, ndi kuthamanga ntchito si lalikulu;Malumikizidwe olimba alibe asidi komanso kukana kwa alkali.Zapadera zimatha kupangidwa ndi chitsulo chosapanga dzimbiri.Kutentha kwa ntchito ndi kupanikizika ndipamwamba kuposa zamagulu okulitsa mphira.Zolumikizira zokulitsa labala ndizotsika mtengo kuposa zolimba zolimba.N'zosavuta kukhazikitsa iwo pamwamba;Mgwirizano wokulitsa mphira umagwiritsidwa ntchito makamaka kuchepetsa kugwedezeka kwa payipi.
