Leak yekuona nzira ye vacuum sintering choto

Kune nzira dzakawanda dzekuonekwa kwekuvuza muvacuum sintering furnaces. Zvinoenderana nemamiriro emidziyo ichaedzwa, inogona kupatsanurwa kuita mhando nhatu: kuvhurika kwebubble, kuwedzera kudzvinyirirwa kudonha kwekuona uye helium mass spectrometry leak yekuona.

1, bubble leak yekuona nzira

Nzira yekuona bubble leak ndeyekudzvanya mweya muchikamu chakatariswa, wobva wainyudza mumvura kana kuzora sipo panzvimbo inofungirwa. Kana pane kudonha pachikamu chakaongororwa, sipo inoputika, iyo inogona kutongwa nekucherechedza mabhubhu. Kuvapo uye nzvimbo yekudonha. Iyi nzira yekuona kuvuza inonyanya kushandiswa panguva dzekuti kubatanidzwa kwechoto chevacuum kuongororwe kwakabatana nemabhaudhi eflange uye kunogona kumirisana nekudzvanywa kwakanaka, uye inogona kushandiswa kuonesa kuvuza mumavira madiki evacuum sintering kana pombi dzevacuum. Kana iyo vacuum sintering furnace ine chimiro chakaomarara, vhoriyamu yakakura, uye nhamba huru yenzvimbo dzakabatana, iyo bubble leak yekuona nzira inowanzo shandiswa padanho rekutanga rekuonekwa kwekudonha. Iyi nzira ine hupfumi uye inoshanda, uye inokwanisa kuwana zvirinani zvekuonekwa kwekudonha.

2, wedzera leak yekuona nzira

Iyo yekudzvinyirirwa-inowedzera yekuvuza nzira ndeyekuisa mvura inovhuvhuta senge acetone kune inofungidzirwa kuvuza kana vacuum mumudziyo wakaedzwa ichisvika pazasi pe100Pa. Kana paine kuvuza, gasi reacetone rinopinda mukati memudziyo wakaedzwa kuburikidza nekudonha. Sarudza kana pane kudonha mumidziyo kubva pakumanikidzwa kunoratidzwa pane vacuum yekutarisa chiridzwa kana paine kamwe kamwe uye kuri pachena kuwedzera, uye kuona kuvepo uye nzvimbo yekudonha. Muchikamu chepakati chevacuum sintering furnace leak yekuona, kureva kuti, kana iyo bubble leak yekuona nzira isingakwanise kuwana zvachose kudonhedza kwemidziyo, iyo yakawedzera leak yekuona nzira inogona kuenderera mberi nekuona kudonha kwemidziyo, uye mhedzisiro yacho yakanaka.

3, helium misa spectrometry leak yekuona nzira

Helium mass spectrometry leak yekuona yakajairika uye yakavimbika vacuum furnace leak yekuona nzira. Iyo inoshandisa iyo magineti deflection musimboti weiyo helium mass spectrometer leak detector, uye inonzwa kune iri kubvinza gasi helium, kuitira kuona nzira yekuona kuvuza. Iyi nzira yekuona kuvuza inoshandisa zvizere kupinda kwakasimba, kuyerera kuri nyore, uye kupararira kuri nyore kwehelium. Iyo yekuvuza yekuona maitiro haisi nyore kukanganisa, haizofungidzirwe zvisizvo, uye ine mhinduro inokurumidza. Paunenge uchiyedza choto chevacuum sintering, tanga wapfekedza pombi, batanidza chinodzingirira chinodonhedza sezvinodiwa, uye batanidza nzvimbo yekutarisa yekuvuza kune yapfuura vacuum pombi zvakanyanya sezvinobvira; chechipiri, funga kutevedzana kwekuona kuvuza kwenzvimbo yekuona kuvuza. Kazhinji kutaura, Iyo inowanzo shanda vacuum chikamu chinopihwa pamberi, senge chisimbiso mhete yevacuum musuwo wekamuri, nezvimwewo, uyezve static mapoinzi eiyo vacuum system, senge vacuum gauge, iyo yekunze flange yevacuum pombi. , nezvimwewo, zvinotariswa, zvichiteverwa nemhepo system uye mvura system.
