A: Maitiro makuru anosanganisira kugadzirisa kusimba kwemugero zvakanaka (kunoongororwa vhiki nevhiki), kuongorora nguva dzose mamiriro echisimbiso uye kuona kudonha kwemvura nekukurumidza, kudzivirira kusukwa kwezvisimbiso zvine simba guru, kutsiva nekukurumidza pamiganhu yekusakara (kusati kwaitika kukuvara kwechipiri), nzira dzekutsiva dzakavakirwa pahurongwa (kuenzanisa maroller matsva necheni yakanaka), uye kudzidziswa kwemushandisi panzira dzakakodzera dzekufamba (kudzikisa kumhanya munzvimbo dzakaoma).

Mubvunzo: Mamiriro e track chain anokanganisa sei hupenyu hwe roller bottom?
A: Cheni yenzira yakasakara (kureba kwepitch kwakanyanya kupfuura 2-3%, chimiro cherail chakasakara) inokurumidza kupera kweroller nekuchinja contact geometry uye kuwedzera dynamic loading. Nzira dzakanakisisa dzeindasitiri dzinokurudzira kutsiva maroller necheni pamwe chete kana kupfeka kwecheni kuchipfuura 2-3% kureba.

Mubvunzo: Ndeipi nzira chaiyo yekuchengetedza maroller epasi ekuwedzera mumabasa ekuchera?
A: Chengeta munzvimbo yakachena, yakaoma yakachengetedzwa kubva kumamiriro ekunze (nzvimbo yekuchengetera mumba ndiyo inonyanya kunaka). Chengeta mupakeji yekutanga ine desiccant kana iripo. Tenderedza nguva nenguva (mwedzi mitatu kusvika mitanhatu yega yega) kudzivirira kusvibiswa kwemvura. Dzivirira kubva mukusvibiswa uye kukuvara. Tevedzera mazano ekuchengetedza emugadziri kuti agare kwenguva refu achivhara mafuta (kazhinji makore maviri kusvika matatu).

Mubvunzo: CQC TRACK iri kupi?
A: CQC TRACK iri muQuanzhou, Fujian Province, China—boka guru remaindasitiri rekugadzira michina yekuvaka rine mukana wekuenda kunzvimbo huru dzepasi rose kuti igoverwe pasi rose zvakanaka.

Bhuku iri rehunyanzvi rakagadzirirwa vatariri vemidziyo vane hunyanzvi, nyanzvi dzekutenga, uye vashandi vekugadzirisa mumabasa ekuchera nekuvaka kwakasimba. Magadzirirwo uye mazano akavakirwa pamitemo yeindasitiri nedata remugadziri rinowanikwa panguva yekuburitswa. Mazita ese emugadziri, nhamba dzezvikamu, uye mazita emhando zvinoshandiswa pakuziva chete. Kune zvinodiwa zvekushandisa uye magadzirirwo echigadzirwa aripo, ndapota bvunza timu yeinjiniya yeCQC TRACK zvakananga.
