Test Profile:
Tembiricha / humidity / yakaderera pressure comprehensive test inonyanya kushandiswa kuona kana chigadzirwa chinogona kumira nekugona kuchengeta kana kushanda mukupisa / humidity / low pressure nharaunda.Zvakadai sekuchengetedza kana kushanda munzvimbo dzakakwirira, kutakura kana kushanda mumakabhini akamanikidzwa kana asina kuvharidzirwa endege, kutakura kunze kwendege, kuratidzwa kune kukurumidza kana kuputika kwekuora mwoyo nharaunda, nezvimwewo.
Njodzi huru dzekudzikira kwemhepo kune zvigadzirwa ndeidzi:
▪Muviri kana kemikari zvinokonzerwa, zvakadai sekugadzirwa kwechigadzirwa, kukuvadzwa kana kuputika, kuchinja kwemuviri nemakemikari zvinhu zvepasi-density zvinhu, kuderedzwa kwekushisa kwekushisa kunokonzera kuti midziyo iwedzere, kuvhara kukundikana, nezvimwewo.
▪Magetsi ekuita senge arcing achikonzera kutadza kwechigadzirwa kana kushanda kusina kugadzikana.
▪ Mamiriro ezvakatipoteredza akadai sekuchinja kwe dielectric properties ye low pressure gasi uye mhepo inotungamirira kuchinja mubasa nekuchengetedzwa kwekuchengetedzwa kwemaitiro ekuedzwa.Pakudzika kwemhepo yemhepo, kunyanya kana yakabatanidzwa nekupisa kwepamusoro, simba re dielectric remhepo rinonyanya kuderedzwa, zvichiita kuti kuwedzera kwengozi ye arcing, pamusoro kana corona discharge.Kuchinja kwezvinhu zvemukati nekuda kwekudzika kana kutonhora kwakanyanya kunowedzera njodzi ye deformation kana kuputika kwemidziyo yakavharwa kana zvikamu pasi pemhepo yakaderera.
Edzai Zvinhu:
Aerospace midziyo, yakakwirira-yakakwirira zvigadzirwa zvemagetsi, zvigadzirwa zvemagetsi kana zvimwe zvigadzirwa
Test zvinhu:
Kudzikira kudzvanywa bvunzo, tembiricha yakakwira uye yakaderera kudzvanywa, yakaderera tembiricha uye yakaderera kudzvanywa, tembiricha / mwando / yakaderera kudzvanywa, nekukurumidza decompression bvunzo, nezvimwe.
Test Standards:
