Maintenance plan ye vacuum choto kubvinza

1. Vacuum furnace vacuum system spool valve pombi yekugadzirisa chirongwa: tarisa kupfeka kwemukati wepombi ye spool valve, ingave iyo shaft musoro yekuisa chisimbiso mhete ye spool valve pombi inodonhedza oiri, mamiriro ekuvharisa evhavhavha ndiro yekubuda. mudziyo, uye iyo vacuum oiri yedunhu Kuisa chisimbiso mamiriro, ingave iyo vacuum pombi oiri yakasvibiswa uye kuyedza iyo yekupedzisira vacuum yeslide valve pombi.

2. Midzi pombi yekugadzirisa chirongwa chevacuum furnace vacuum system: tarisa kusiyana pakati pe rotor ne rotor ye Roots pombi, uye pakati pe rotor uye mukati memadziro emukati wepombi yepombi, tarisa kupfeka kwegiya nemabhengi, uye mamiriro. yemhete yekusimbisa shaft yepombi yeRoots. Tarisa uone kana oiri yekuzora kumativi ese epombi yeRoots yakasvibiswa uye edza iyo yekupedzisira vacuum yepombi yeRoots.

3. Kugadzirisa chirongwa chepombi yekuparadzira muvacuum system yevacuum furnace: tarisa kuti zvinzvimbo uye mapundu ezviputi pamatanho ese epombi core ndizvo, ingave simba rekudziya repombi uye kutonhora kwepombi pachayo. zvakajairika, ingave mafuta epombi yekuparadzira akaiswa oxidized, uye kuti vhoriyamu yemafuta epombi yekuparadzira inozadzisa zvinodiwa. Kuonekwa kwekuvuza kwepombi yekuparadzira uye pombi dzayo dzakabatana nemavharuvhu, nzvimbo dzekuyeresa dzevacuum, matepi anotonhora nezvimwe zvisimbiso. Edza iyo yekupedzisira vacuum yepombi yekuparadzira. Tarisa tembiricha uye kuyerera kweinopinza uye yekubuda mvura yevacuum furnace diffusion pombi. Mumayuniti mazhinji, kutonhora kwepombi yekuparadzira hakuna kunaka nekuda kwechiyero mumvura inotonhorera, izvo zvinoita kuti vacuum degree itadze kuzadzisa zvinodiwa zvetechnical index. Mvura inotonhorera inogona kuwedzerwawo.

4. Kugadzirisa chirongwa chekunze kwemhepo inodonha chikamu chechoto chisimbiso: chisimbiso chegonhi rechoto, iyo huru valve stem chisimbiso, pneumatic ball valve stem seal, vent valve spool chisimbiso, kuputika-proof valve spool chisimbiso, pre- yekubvisa vharafu stem chisimbiso, uye thermocouple Kuisa chisimbiso uye kudziyisa electrode chisimbiso uye dzimwe nzvimbo dzakanamwa kuti ione kuvuza.

5. Venting yekugadziridza chirongwa chemukati wevacuum choto chemoto: Nyatsopisa mukati mevacuum choto chemoto kuburitsa adsorbed gasi mukati mechoto muviri uye kupomba kure. Paunenge uchitsvaira, argon uye nitrogen inozadzwa muchoto chevira, kuitira kuti chikamu chechinhu chinoputika uye adsorbed gasi chinokweverwa kure pamwe neargon uye nitrogen. Wokwesha madziro emukati mechoto muviri nedoro kubvisa adsorbed nyaya uye kuderedza kuwanda kwekubuda. Vacuum kamuri yevira kwenguva yakareba kuti uderedze mhepo yekamuri yevira kusvika kune yakaderera.
