Zvishandiso Zvitatu zveTsvimbo Dzepasi Pakutarisisa

1. Tsvimbo yesimbi yakaputirwa nemhangura (CCS)

Matavi esimbi akaputirwa nemhangura ane musimboti wesimbi ine kabhoni shoma ine simba guru (kabhoni iri ~0.15%) ine kabhoni yakasungirirwa kuburikidza ne electroforming. Kuchena kwemhangura kuri ≥99.95%, uye ukobvu hwekabhoni hwakajairwa huri ≥0.254 mm.Tsvimbo yesimbi yaSHIBANG yakagadzirwa nemhanguramutsetse, dhayamita dzinotangira pa14.2 mm kusvika 25 mm (5/8″ kusvika 3/4″), kureba kubva pa1.2 m kusvika 3.0 m, uye simba rekudhonza ≥580 N/mm².

Ndichiri kuyeuka ndakamira padivi petambo yedu yemagetsi pafekitori yaSHIBANG, ndichiona danda re16 mm CCS richibuda mutangi repurasitiki. Mushandi anoongorora danda rega rega nechiyero chekukora kwemagineti— mudziyo unobatwa nemaoko unoverenga ukobvu hwemhangura nekuyera kukwezvana kwemagineti kuburikidza nemhangura. Batch imwe chete yakaratidzwa nekuti gauge yaiverenga 0.248 mm pamucheto wekutyaira — ma microns matanhatu chete pasi pe 0.254 mm spec. Batch yese yakadzokera kunogadziriswazve. Kuranga ikoko kunokosha kana tsvimbo yapera muvhu regungwa kune rumwe rutivi rwenyika.

Rutivi rwemhangura runopakuramba ngura uye kufambisa kwemhangura yakachena pamusoro, nepo simbi iri pakati ichipa simba rekushandisa muvhu rakakora. Chisungo chemhangura nesimbi chinoedzwa nekukombamisa tsvimbo 90° pa 100 mm pasina kutyoka kana kucheka. Hupenyu hwebasa muvhu rakajairika hunodarika makore makumi mashanu. Musanganiswa uyu ndosaka CCS iriyo default earthing specification pasi rose.

2. Tsvimbo yePasi yeMhangura Yakachena

Matavi emhangura akachena anoshandisa mhangura yeT2 (≥99.95% yakachena).Tsvimbo yesimbi yemhangura chaiyo yaSHIBANGpeji, sarudzo dzakafanana dzedhayamita nehurefu seCCS dziripo. Asi mhangura inodhura zvakanyanya kupfuura simbi pakirogiramu imwe neimwe. Tsvimbo yemhangura yakasimba inopa simba rakaderera kune dhayamita yakatarwa, ine simba rakanaka rekuora muvhu rine simba. Zvisinei, mhangura yakachena yakapfava - kutyaira muvhu rine matombo kana rakamanikana kunogona kukonzera kugocha kana kuomesa mugumo, ndosaka vashandi vazhinji vachiboorera maburi ekutanga. Basa iroro rekuwedzera rinowedzera kumutengo wezvinhu zvatove wakakwira.

Mumwe muvaki wekuManila akambondifonera, achishungurudzika kuti matanda esimbi esimbi ari panhare yake yenharembozha yaiva pagomo akanga aita ngura mushure memakore mana chete ari muvhu regungwa. Kutsiva kwacho kwaida kucherwa panheyo yekongiri inoshanda. Basa racho roga rakapfuura mari yaizoshandiswa nematanda eCCS pakutanga. "Ndaifanira kunge ndakateerera data remvura yemunyu yawakandiratidza," akabvuma. Kufona ikoko kwakaramba kuri mupfungwa dzangu - ndosaka ndichibvunza mutengi wese nezvemamiriro evhu kutanga.

3. Tsvimbo yesimbi inopisa inonyudzwa nesimbi

Matavi esimbi akagadzika isimbi isina kabhoni yakawanda ine zinc coating inoshandiswa kuburikidza nekupisa-kunyika galvanizing. Zinc layer inopa dziviriro yekuzvipira - inotanga yaora, ichidzivirira simbi iri pasi.Tsvimbo yevhu yaSHIBANG yakagayiwa negiraziMutsetse wechigadzirwa, tsvimbo idzi dzine saizi dzakafanana asi dzine mutengo wakaderera pakati pesarudzo nhatu idzi.

Ukobvu hwezinc coating hunowanzova pakati pe55 kusvika 85 µm. Muvhu rine pH isina kusimba uye rine mvura yakanaka, galvanized rod inogona kugara kwemakore 15-25. Asi muvhu rine acidic (pH iri pasi pe5.5) kana munyu, zinc layer inogona kudyiwa mukati memakore 5-8, mushure mezvo simbi inoora nekukurumidza. Ndakaona galvanized rods dzichibviswa kubva kumapurojekiti emahombekombe mushure memakore matanhatu chete zinc yapera zvachose. Tinoshandisa nzira dzese dzekushandisa.imba yekupfapfaidza munyupa5% NaCl kwemaawa makumi manomwe nemaviri - bvunzo iyoyo inoratidza maburi ari mu zinc coating ayo pasina kuongororwa nemaziso kwaizomboonekwa.

Matavi esimbi akapendwa ane mashandisirwo ari pamutemo. Kuisa pasi kwekuvaka kwenguva pfupi, mapurojekiti enguva pfupi (makore mashanu kusvika gumi ekugadzira), uye nzvimbo dzakaoma dziri mukati menyika dzine ivhu re pH risina kuenzana zvese zvinonzwisisika kushandiswa. Ndinopa zano kune vatengi kuti vasataure nezvemagadziko ekugara munzvimbo dzine mvura inonaya pagore inopfuura 800 mm, nzvimbo dziri mumahombekombe dziri mukati memakiromita gumi nemashanu kubva mumvura ine munyu, kana nzvimbo dzemaindasitiri dzine makemikari.tsvimbo yevhu yakagayiwachigadzirwa chakasimba kana chikumbiro chacho chakakodzera.
