ASME SA179 chiyero chemapombi esimbi asina musono emuchina wekupisa wakagadzirwa neAmerican Society of Mechanical Engineers (ASME), iyo inotsanangura zviratidzo zvakakosha zvakaita semaitiro ekugadzira, kuumbwa kwemakemikari, hunhu hwemakanika uye kushivirira kwepaipi nehukuru hwayo. Chiyero ichi chinovimbisa kuti pombi yesimbi ine simba rakanaka rekudzivirira kumanikidzwa, kufambisa kupisa uye kuramba ngura muzvishandiso zvakasiyana-siyana zvekupisa, uye yakakodzera mamiriro ekushanda akaomarara mumakemikari, magetsi, chikafu nedzimwe nzvimbo.
Zvakanakira zvikuru zvemaitiro ekudhirowa anotonhora
Pombi yemusono inodhonzwa inotonhora yeAmerica inoshandisa tekinoroji yekudhirowa tembiricha yemumba uye inogadzirwa nemazvo nemolds. Ine hunhu hunotevera:
Saizi yakanyatsojeka: kutsungirira kwakasimba kwedhayamita yekunze (senge ± 0.10mm), ukobvu hwemadziro hwakafanana, hwakakodzera chimiro chekupisa chinovhara zvakanyanya.
Kusimbisa hunhu hwemakanika: kushanduka kwechando kunoita kuti tsanga dzitarire, kunovandudza simba rekudhonza (≥325MPa) uye kuomarara, ukuwo zvichiramba zvakasimba.
Hunhu hwakanaka hwepamusoro: madziro emukati akatsetseka (kuomarara kweRa≤0.8μm), anoderedza kuramba kwemvura, uye anovandudza mashandiro ekuchinjana kwekupisa.
Zvimiro zvehukuru hwekiyi
ASME SA179 inosanganisira zvakasiyana-siyana zvinodiwa kuti zvienderane nezvinodiwa nemamiriro akasiyana ekuchinjana kwekupisa:
Chiyero chedhayamita yekunze (mm) Chiyero cheukobvu hwemadziro (mm) Mamiriro ezvinhu akajairika ekushandisa
12.7~25.4 1.24~2.11 Chinochinja kupisa kweplate diki
25.4~38.1 2.11~3.81 Muchina wekupisa wemakemikari nechubhu
38.1~50.8 3.81~5.59 Kondensa yemagetsi ine simba rakawanda
Nyaya dzekushandisa muindasitiri
1. Indasitiri yemakemikari
Kuchenesa peturu: Mapakeji echubhu yekuchinjisa kupisa anoshandiswa muma hydrogenation reactors, anodzivirira hydrogen sulfide corrosion (H₂S concentration ≤50ppm).
Kugadzirwa kweasidhi yesulfuric: Kutonhodza gasi reSO₂ rinopisa zvakanyanya (≤450℃), chifukidziro chekudzivirira ngura chinodiwa pakushandisa simbi yekabhoni.
2. Simba remagetsi
Mapaipi eCondenser: Mumafekitori emagetsi anodziya, mapaipi esimbi eSA179 anodzivirira kumanikidzwa kwemhepo ye0.1MPa, ine conductivity yekupisa ye50W/(m·K), uye kuwedzera kwekushanda kwecondensation kwe15%.
