Q: Kodi ndingasankhe bwanji pakati pa ma configurations osiyanasiyana a bottom roller pa ntchito zolemera?
A: Kusankha kumadalira: kufotokozera za unyolo wa njanji (pitch, rail profile, bushing diameter), makina ogwiritsira ntchito (mtundu wa migodi, malo, ma slope angles), momwe ntchito ikuyendera (mlingo wa kuipitsidwa, nyengo, kusakhazikika kwa zinthu), ndi zofunikira pakugwira ntchito (zolinga za moyo wautumiki, zoletsa mtengo). Thandizo la uinjiniya kuchokera kwa opanga monga CQC TRACK lingathandize kusankha bwino.

Q: Kodi kusiyana pakati pa ma rollers apansi a single-flange ndi double-flange ndi kotani?
Yankho: Ma double-flange roller amapereka malo abwino osungira njanji mbali zonse ziwiri, ndipo amagwiritsidwa ntchito kwambiri poyendetsa mbali ndi malo otsetsereka komanso kugwiritsa ntchito kwambiri. Ma single-flange roller amalola kuti pakhale kusakhazikika bwino ndipo nthawi zambiri amagwiritsidwa ntchito mkati mwa njanji yokha. Kwa ma excavator a class class a matani 70, ma double-flange roller ndi okhazikika mbali zonse ziwiri.

Q: Kodi ndimayesa bwanji kutayika kwa roller pansi molondola?
A: Miyeso yofunika kwambiri ikuphatikizapo: dayamita yakunja (pogwiritsa ntchito ma caliper akuluakulu kapena tepi ya pi), makulidwe a flange (ma caliper), radial play (dial indicator yokhala ndi pry bar), axial play (dial indicator yokhala ndi axial loading), ndi seal gap (feeler gauges). Lembani miyeso nthawi ndi nthawi kuti mudziwe kuchuluka kwa kuwonongeka.

Q: Kodi zizindikiro zotani zosonyeza kuti kusintha kwa roller pansi kuli pafupi?
A: Zizindikiro zikuphatikizapo: kutuluka kwa chisindikizo chooneka, kuzungulira kozungulira komwe kumamveka potembenuza ndi manja, kutentha kwakukulu kogwira ntchito (komwe kumaonekera pokhudza kapena infrared), phokoso losazolowereka panthawi yogwira ntchito (kukupera, kugunda), kuwonongeka kwa flange komwe kumaoneka ndi m'mbali zakuthwa, ndi kusewera koyezeka kopitilira zomwe zafotokozedwa.

Q: Kodi ma roller apansi angamangidwenso kapena kupangidwanso?
A: Inde, ntchito zodziwika bwino zokonzanso zinthu zitha kusintha ma bearings ndi ma seal, kumanganso ma treads ndi ma flanges osweka kudzera mu hardfacing, ndikubwezeretsa zinthu kukhala zatsopano pa 50-70% ya mtengo watsopano. CQC TRACK ikupanga luso lokonzanso zinthu kuti zithandizire zolinga zokhazikika.

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

Q: Kodi njira yoyenera yosungira ma roller owonjezera pansi ndi iti?
Yankho: Sungani pamalo oyera komanso ouma otetezedwa ku nyengo. Sungani m'maphukusi oyamba okhala ndi desiccant ngati alipo. Sinthasinthani nthawi ndi nthawi (miyezi 3-6 iliyonse) kuti mupewe kuipitsidwa ndi madzi. Tetezani ku kuipitsidwa ndi kuwonongeka. Tsatirani malangizo a wopanga kuti musunge mafuta nthawi yayitali komanso kuti mafuta azikhala nthawi yayitali.

Buku laukadaulo ili lapangidwira oyang'anira zida zaukadaulo, akatswiri ogula zinthu, ndi ogwira ntchito yokonza zida 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 pongodziwitsa okha. Nthawi zonse funsani zikalata za zida ndi akatswiri oyenerera aukadaulo kuti mudziwe zomwe zingagwiritsidwe ntchito.
