Conas seiceáil a dhéanamh ar shéalú an tsraith inslithe de chorna téimh leictreach cruach dhosmálta séalaithe táthaithe?

Seiceáil séalaithe an tsraith inslithe den chorna téimh leictreach cruach dhosmálta atá séalaithe táthaithe ag na modhanna seo a leanas:
Iniúchadh cuma
Breathnaigh go díreach ar chuma an táthaithe chun a fháil amach an bhfuil an táthú leanúnach agus aonfhoirmeach, agus an bhfuil lochtanna soiléire ar nós pores, scoilteanna, cuimsiú slaig, etc . má tá an dromchla táthaithe réidh agus cothrom, agus níl aon bhearnaí infheicthe nó poill infheicthe ann, léirítear go bhfuil an séalaithe go maith {{}}}, léirítear go réamhbheartaithe go bhfuil an séalaithe go maith {{}}}}
Seiceáil an nasc idir an ciseal inslithe agus an corna téimh leictrigh agus comhpháirteanna gaolmhara eile chun a fháil amach an bhfuil bearnaí, díorma nó ábhair ina saothraítear rónta ar iarraidh .
Brú
Tástáil brú aeir: Cuir an corna teasa leictreach i spás dúnta, cuir brú áirithe gáis (mar shampla), agus ansin bain úsáid as boilgeoga gallúnaí nó leacht braite sceite speisialta chun iarratas a dhéanamh ar an gcuid táthúcháin agus pointí sceite féideartha . Má ghintear boilgeoga, ciallaíonn sé go bhfuil sceitheadh ​​ann agus nach bhfuil an séala go maith {{}}}
Water pressure test: For some electric heating coil systems that can withstand water pressure, they can be filled with water and a certain pressure can be applied to observe whether there is water seepage in the welding part and the surrounding area. The pressure of the water pressure test is generally determined according to the design requirements and use environment of the electric heating coil, which is usually slightly higher than the actual working pressure.
Helium mass spectrometry leak detection: This is a high-precision leak detection method suitable for occasions with high requirements for sealing. Place the electric heating coil in a sealed test chamber, fill it with a certain amount of helium, and then use a helium mass spectrometer leak detector to detect the concentration of helium in the surrounding environment. If helium leakage is Ciallaíonn sé go bhfuil fadhb ann le séalaithe an chiseal inslithe . Is féidir leis an modh seo sceitheadh ​​an -bheag a bhrath le híogaireacht ard, ach tá costas an trealaimh sách ard .
Vacuum test: Place the electric heating coil in a vacuum environment and observe the changes in its internal pressure. If the pressure rises significantly within a certain period of time, it means that air or other gases have entered, that is, there is a sealing problem. A vacuum gauge can be used to accurately measure the pressure change to determine the quality of the sealing.
