Q: Kodi ubwino wopeza zinthu zokumbira migodi kuchokera ku CQC TRACK ndi wotani?
A: CQC TRACK imapereka mitengo yopikisana (30-50% kuposa OEM), luso lopanga zinthu za migodi yokhala ndi aloyi yapamwamba ya SAE 4140 ndi kuuma kwa pamwamba kwa HRC 58-62, makina otsekera owonjezera magawo ambiri kuti awonongeke kwambiri, chitsimikizo chapamwamba (chovomerezeka cha ISO 9001, kuwunika kwa 100% UT, kutsimikizira mayeso), komanso ukatswiri waukadaulo pakugwiritsa ntchito migodi.

Q: Kodi momwe ntchito yogwirira ntchito m'migodi imakhudzira bwanji moyo wa roller pansi?
A: Zinthu zomwe zimachepetsa moyo wa ma roller ndi monga: kuchuluka kwa quartz/silika mu miyala (kumathandizira kuwonongeka kwa abrasive ndi nthawi 2-3), kuwonekera m'madzi/matope (kumawonjezera kupsinjika kwa seal ndi chiopsezo cha kuipitsidwa), kutentha kwambiri (kumakhudza mafuta ndi zinthu zomatira), kutsika kwa mphamvu (kumathandizira kutopa kwa bearing), kugwira ntchito kwa mbali (kumawonjezera kuwonongeka kwa flange), ndi kuyenda kothamanga kwambiri (kumawonjezera kutentha ndi kuchuluka kwa kuwonongeka).

Q: Ndi njira ziti zosamalira zomwe zimawonjezera nthawi yogwira ntchito mu migodi?
Yankho: Njira zofunika kwambiri ndi monga kukonza bwino kupsinjika kwa msewu (kumayang'aniridwa sabata iliyonse), kuyang'ana nthawi zonse momwe chisindikizo chilili komanso kuzindikira kutayikira koyambirira, kupewa kutsuka zisindikizo mwamphamvu, kusintha mwachangu pamalire owonongeka (kusanachitike kuwonongeka kwachiwiri), njira zosinthira pogwiritsa ntchito makina (kufananiza ma rollers atsopano ndi unyolo wabwino), ndi maphunziro a ogwiritsa ntchito njira zoyenera zoyendera (kuchepetsa liwiro pamalo ovuta).

Q: Kodi mkhalidwe wa unyolo wa njanji umakhudza bwanji moyo wa roller pansi?
A: Unyolo wosweka (kutalika kwa ma pitch opitilira 2-3%, mawonekedwe a njanji osweka) umathandizira kuwonongeka kwa ma roller mwa kusintha mawonekedwe a contact ndikuwonjezera kukweza kwamphamvu. Njira zabwino kwambiri zamakampani zimalimbikitsa kusintha ma roller ndi unyolo pamodzi pamene kuwonongeka kwa unyolo kupitirira kutalika kwa 2-3%.

Q: Kodi njira yoyenera yosungira ma rollers otsala pansi pa ntchito zamigodi ndi iti?
Yankho: Sungani pamalo oyera komanso ouma otetezedwa ku nyengo (ndi bwino kusunga mkati). Sungani m'mabokosi ake oyambirira okhala ndi desiccant ngati alipo. Sinthasinthani nthawi ndi nthawi (miyezi 3-6 iliyonse) kuti mupewe kusungunuka kwa madzi oundana. Tetezani ku kuipitsidwa ndi kuwonongeka. Tsatirani malangizo a wopanga osungira kuti mafuta azikhala nthawi yayitali (nthawi zambiri zaka 2-3).

Q: Kodi CQC TRACK ili kuti?
A: CQC TRACK ili ku Quanzhou, m'chigawo cha Fujian, China—gulu lalikulu la mafakitale opanga makina omangira okhala ndi mwayi wopita ku madoko akuluakulu apadziko lonse lapansi kuti agawidwe bwino padziko lonse lapansi.

Buku laukadaulo ili lapangidwira oyang'anira zida zaukadaulo, akatswiri ogula zinthu, ndi ogwira ntchito yokonza zinthu m'migodi ndi ntchito zomanga nyumba zolemera. Mafotokozedwe ndi malangizo amachokera ku miyezo yamakampani ndi deta ya opanga yomwe ilipo panthawi yofalitsa. Mayina onse opanga, manambala a magawo, ndi mayina a zitsanzo amagwiritsidwa ntchito podziwitsa okha. Pazofunikira zinazake zogwiritsira ntchito ndi mafotokozedwe azinthu zomwe zilipo, chonde funsani gulu la mainjiniya la CQC TRACK mwachindunji.
