Scientific Maintenance Nzira dzePFA Mapaipi uye Welding tsvimbo

Mumaindasitiri akadai semakemikari, semiconductors, uye kugadzira chikafu, mapombi ePFA netsvimbo dzewelding anoshandiswa zvakanyanya nekuda kwekushomeka kwavo kwekuora uye kupisa kwakanyanya. Zvisinei, kana dzikasachengetwa zvakanaka, upenyu hwavo hwebasa nekushanda kwavo hunogona kuderedzwa zvikuru. Ichi chinyorwa chinosuma nzira dzakaringana dzekugadzirisa dzePFA pombi uye welding tsvimbo kubatsira vashandisi kuwedzera hupenyu hwavo hwesevhisi uye kuve nechokwadi chekushandiswa kwakakwana.

Maintenance points emapombi ePFA

Kusaita ngura uye kuchinjika kwepombi dzePFA dzinoita kuti dzive dzakanakira kutakura zvinwiwa zvinoora, asi mushure mekushandisa kwenguva refu-, dzinogona kuzosangana nematambudziko akadai sekuchembera, kumonereka, kana kusvibiswa kwemukati memadziro. Aya anotevera matanho akakosha ekugadzirisa:

Geza madziro emukati nguva nenguva
Rusvingo rwemukati rwemapombi ePFA runogona kukanganisa kuyerera uye kuchena nekuda kwekusara kwemvura kana kuunganidzwa kwezvinosvibisa. Zvinokurudzirwa kugara uchisukurudza pombi ne-zvinonyungudutsa zvine mucheno zvakakwirira (senge isopropyl alcohol kana mvura yakasvibiswa) uye kudzivisa kushandisa asidhi yakasimba kana mishonga yealkaline yakasimba kudzivirira kukoronga kwemadziro epombi.

Dzivisa kukuvara kwemichina
Kunyangwe mapaipi ePFA achichinjika, kupeta zvakanyanya kana kudzvanya kunogona kukonzera kutsemuka kana deformation yemadziro emukati. Panguva yekuisa, ita shuwa kuti kubhenda radius yepombi inosangana nekurudziro yemugadziri uye kudzivirira kubhenda kwakapinza.

Dzora tembiricha yekushandisa
Kureba-tembiricha yekushandisa kwePFA pombi kazhinji -200℃kusvika +260℃. Kupfuura mutsara uyu kunogona kuita kuti zvinhu zvipfave kana kuti embrittle, zvichikanganisa simba rayo remagetsi uye kugadzikana kwemakemikari.

Dzivisa-nguva refu kuratidzwa kwemwaranzi yeultraviolet
Kunyange zvazvo PFA isingadzivirirwe nemwaranzi yeultraviolet, kuratidzwa kwenguva refu-kuchiedza chakasimba kunogona kuita kuti kushanda kwezvinhu zvishate. Inokurudzirwa kushandisa chiedza chekudzivirira matanho ekudzivirira kunze kana munzvimbo dzakasimba dzechiedza.

Nzira dzekuchengetedza dzePFA welding rods

PFA welding tsvimbo dzinoshandiswa pakubatanidza mapombi, uye kuchena kwavo uye kuchena kunokanganisa zvakananga kunaka kwewelding. Aya anotevera mapoinzi akakosha ekugadzirisa welding rod:

Chengetedza munzvimbo yakaoma
PFA welding rods ine yakaderera hygroscopicity, asi ichiri kuda kuchengetwa munzvimbo yakaoma uye inotonhorera kudzivirira hunyoro hunokanganisa kushanda kwewelding. Inokurudzirwa kushandisa mudziyo wakavharwa kudzivirira guruva kana tsvina kubva pakusvibiswa.

Dzivisa-kuchengetera kupisa kwepamusoro
Welding rod inogona kupfava kana kukanganiswa munzvimbo -inopisa zvikuru, zvichikanganisa kushanda kwewelding. Inokurudzirwa kuichengeta munzvimbo iri pasi pe50℃uye kure nekupisa.

Tarisa utsanana usati washandisa
Usati waputira, tarisa kana pane zvakasvibiswa kana zvikweshwa pamusoro petsvimbo yewelding. Kana zvichidiwa, pukuta neguruva{1}}jira remahara kuti uone kuti nzvimbo yewelding yakatsetseka uye yakachena.

Ronga zvine musoro kuwanda kwetsvimbo yewelding inoshandiswa
Welding rod inofanira kushandiswa nekukasika mushure mekuvhurwa kuti isazogara kwenguva refu-pamhepo, izvo zvinogona kukonzera kuderera kwekushanda. Tsvimbo dzewelding dzisina kushandiswa dzinofanira kuvharwa pakuchengetedza.

Kuburikidza nesainzi nzira dzekuchengetedza, kuita uye hupenyu hwePFA pombi uye welding tsvimbo inogona kuvandudzwa zvakanyanya. Kugara kugadziridza hakugone chete kuderedza kutsiva mutengo, asi zvakare kuve nechokwadi kugadzikana uye kuchengetedzeka kwemaitiro ekugadzira.
