Nhanganyaya
Mabhoti zvinhu zvakakosha mumidziyo yeindasitiri uye masisitimu ehurongwa. Munzvimbo dzinopisa-pamusoro, mabhaudhi haafanire kushingirira kwete kungoremerwa nemichina asiwo kupisa kwakanyanya, kuwedzera kwemafuta, oxidation, uye kushushikana kwenguva refu-. Maindasitiri akadai sekugadzira magetsi, petrochemical processing, aerospace, kugadzira mota, metallurgy, nekugadzirwa kwemaindasitiri echoto zvese zvinoenderana nepamusoro-mabhaudhi ekudziya kuchengetedza kugadzikana kwemidziyo uye kusashanda zvakanaka.
Kusarudza mabhaudhi asina kunaka emamiriro ekushisa akakwira kunogona kutungamirira kumatambudziko akakomba. Kupisa kwakanyanya kunogona kuderedza simba rekusimba, kuderedza simba rekusunga, kukurumidza kukora, kana kukonzera kukanganisa kwekufamba kwenguva. Muzviitiko zvakakomba, kutadza kwebhaudhi kunogona kukonzera kudzimwa kwemidziyo, njodzi dzekuchengetedza, kugadzirisa kunodhura, uye kurasikirwa kwekugadzira.
Vatengi vakawanda vemumaindasitiri vanotarisa kuhukuru hwebhaudhi uye giredhi resimba, asi -tembiricha yemhando yepamusoro inoda kutariswa zvakadzama. Kuumbwa kwezvinhu, oxidation kuramba, kupisa kuneta kuita, dhizaini yeshinda, uye nzira dzekuisa zvese zvinopesvedzera kuvimbika kwebhaudhi pasi pekupisa.
Chinyorwa chino chinotsanangura nzira yekusarudza mabhaudhi akakodzera kune-nzvimbo dzetembiricha yepamusoro uye chinoratidza zvinhu zvakakosha zvinokanganisa kushanda kwefastener mumamiriro ekuda maindasitiri.
Nzwisisa Mashandiro eMamiriro eKunyanya-Kupisa Kwemamiriro ekunze
Usati wasarudza mabhoti, zvinodikanwa kuti uongorore iyo chaiyo yekushanda nharaunda. Kusiyana kwekushisa kwemamiriro ezvinhu kunoda zvinhu zvakasiyana-siyana zvebhaudhi uye michina yemagetsi.
Ziva Working Temperature Range
Nhanho yekutanga ndeyekutarisa kupisa kwekushanda kwemidziyo. Mamwe masisitimu anoshanda anoramba ari pakati nepakati tembiricha akatenderedza 200 dhigirii kusvika 400 dhigirii, nepo mamwe anogona kudarika 800 dhigirii kana kunyange 1000 dhigirii mukunyanyisa maindasitiri kunyorera.
Standard carbon steel bolts inogona kuita zvakanaka pakudziya kwakajairika, asi simba rawo rinodzikira nekukurumidza pasi pekuratidzwa kupisa kwenguva refu. Kukwirisa-kupisa kunoda mabhaudhi akagadzirirwa kuchengetedza zvinhu kana tembiricha yakakwira.
Mainjiniya anofanirwawo kusiyanisa pakati pekuenderera kwekushanda tembiricha uye tembiricha yepamusoro. Nguva pfupi-kutarisana nekupisa kwakanyanya kungada zvinhu zvakasiyana-siyana zvebhaudhi zvichienzaniswa nekuramba kuchipisa-kwenguva refu.
Ongorora Thermal Cycling Mamiriro
Mazhinji maindasitiri masisitimu anoona anodzokororwa kudziyisa uye kutonhora kutenderera. Maboiler, masisitimu ekupedza simba, turbines, uye maindasitiri mareactor anowanzo kuwedzera panguva yekushanda uye chibvumirano panguva yekudzima.
Thermal cycling inogadzira kushushikana mukati memabhaudhi uye zvinhu zvakabatana. Kuwedzera kudzokororwa uye kuputika kunogona kusunungura majoini zvishoma nezvishoma kana kukonzera kuneta kutsemuka. Nokufamba kwenguva, kuneta kwekupisa kunogona kuderedza chisungo uye kuwedzera njodzi yekukundikana.
Mabhaudhi anoshandiswa munzvimbo dzinopisa dzekuchovha bhasikoro anofanirwa kupa kuneta kwakasimba kuramba uye yakagadzikana yekusunga simba pasi pekuchinja kwekushisa.
Ongorora Mutoro uye Kumanikidza Zvinodiwa
Yepamusoro-midziyo yetembiricha inowanzoshanda pasi pemitoro inorema uye nepakati pesimba. Zvichipisa zvinopisa, mapaipi ehutsi, midziyo yekumanikidza, uye vira remaindasitiri zvinoisa kushushikana kwakanyanya pamasisitimu ekusimbisa.
Pane tembiricha dzakakwirira, mabhaudhi zvinhu zvinorasikirwa nechikamu chekusimba kwavo. Uku kuderedzwa kwesimba kunokanganisa kugona kwemabhoti kuchengetedza preload uye kubatana kutendeseka.
Kusarudza mabhaudhi ane mutoro wakakwana-anotakura simba patembiricha yekushandisa kwakakosha pakuchengetedzeka kwemidziyo.
Ongorora Environmental Exposure
Tembiricha haisiriyo yega chinhu chinokanganisa kuita kwebhoti. Kukwirira-mhoteredzo yetembiricha inogonawo kusanganisira oxidation, mwando, makemikari, kana magasi anoparadza.
Semuyenzaniso:
