Kuti uwedzere hupenyu hwebasa reHeli CQCTRACK lower roller assemblies muHITACHI ZX850/ZX900 mining applications, nzira dzinotevera dzekugadzirisa dzinokurudzirwa:

7.1 Nzira Yekuongorora Nguva Dzose

• Nguva Yokuongorora: Ongorora marollers panguva yemaawa mazana maviri nemakumi mashanu (kazhinji kana paine zvinhu zvakanyanya kushandiswa mukuchera) kuti uone kana paine humbowo hwekubuda kwemafuta, mapatani asina kunaka ekupfekwa, nzvimbo dzakati sandara, kana kukuvara kunooneka.
• Kuongorora Zvinhu Zuva Nezuva: Kuongorora zvinhu zuva nezuva kunofanira kusanganisira kuongorora kuti hazvina kutenderera here, mafuta ari kubuda (zvichiratidza kuti chisimbiso chakanganiswa), uye kusakara kweflange.
• Kuyera Kupfeka: Kuyera nguva dzose kukwirira kweflange uye dhayamita yeroller zvichienderana nemiganhu yebasa kwakakosha.
• Kuongorora Kutenderera: Iva nechokwadi chekuti maroller ese anotenderera zvakasununguka—roller yakabatwa ichaonekwa kuti yakarembera uye inokonzera kupera kwecheni yemumugwagwa nekukurumidza. Chero roller ine kutenderera kwakaganhurirwa inofanira kutsiviwa nekukasika.

7.2 Maitiro Ekuongorora Chirwere

• Kuongorora Zvinoonekwa: Tarisa kana roller surface isina kuenzana, izvo zvinogona kuratidza kuti zvinhu hazvina kurongeka zvakanaka kana kuti hazvina kumira zvakanaka.
• Kuona Kubuda Kwemvura: Ongorora kana mafuta asina kubuda, zvinoreva kuti chisimbiso chakundikana.
• Kuongorora Kunzwa: Teerera ruzha rwekukuya kana kurira panguva yekushanda, izvo zvinogona kuratidza kusakwana kwekunyorovesa kana kukuvara kwemabheya.
• Kuongorora Mutambo: Tarisa kana kutamba kwakanyanya kana kuzununguka, zvinoreva kuti mabheya akasakara.

7.3 Kuchengetedza Kudzivirira

• Kutarisira Kushushikana Kwenzira: Chengetedza kushushikana kwenzira zvichienderana nezvinodiwa nemugadziri weHITACHI. Kushushikana kusina kunaka ndicho chikonzero chikuru chekukurumidzira kupera kweroller—kunyanya kuomarara kunowedzera kupera kwemabearing netread; kusunuruka kwakanyanya kunokonzera kurohwa kwenzira uye kukuvara kwekukuvara.
• Nzira Yekuchenesa: Gara uchichenesa marara nevhu pasi pechitsiko kudzivirira kukuvara kwechisimbiso nekukurumidza. Mumigodhi, kugeza nemhepo ine simba kunofanirwa kuitwa nguva dzose.
• Kuongorora Kurongeka: Nguva nenguva ongorora kurongeka kwakakodzera kweroller nefuremu yenzira. Kana maroller akaratidza kusakara kweflange kusina kuenzana, izvi zvinoratidza kusarongeka kunoda kuferefetwa.
• Kuzora Mafuta Kwakakodzera: Kushandisa mafuta akasarudzwa anodziya zvakanyanya panguva dzakakurudzirwa. Kuzora mafuta zvakanyanya kunogona kukuvadza zvisimbiso, nepo kudzora mafuta zvishoma zvichikonzera kusakwana kwemafuta uye kupisa zvakanyanya.
• Kutsiva Kwakarongeka: Tsiva maroller akasakara mumaseti akafanana padivi rimwe chete kuti mutoro ugoverwe zvakaenzana uye kuti uchengetedze mari yekutakura. Kutsiva roller imwe chete yakasakara pakati pemamwe akasakara kunogona kukonzera kugoverwa kwemutoro kusina kuenzana uye kukurumidza kutadza kushanda kwechikamu chitsva.

7.4 Nhungamiro dzeKutsiva Nzvimbo yeMugero

Tsiva zvikamu zve sprocket kana:

• Kupera kwezino kunodarika kudzikiswa kwe8-12mm kubva paprofile yepakutanga
