Zifukwa ndi Mayankho a Kugwedezeka Kwambiri kwa Screen Yogwedezeka
1, Eccentric vibration ya exciter
Mphamvu ya centrifugal yomwe imapangidwa ndi kulemera kwa eccentric panthawi ya ntchito ya vibration exciter idzapindika tsinde la eccentric, ndikupangitsa kuti mphete yamkati ndi mphete yakunja ikhale yosiyana. Eccentricity imatulutsa kugwedezeka komwe kumachitika chifukwa cha kusinthasintha kwafupipafupi komanso ma frequency ake a harmonic.
Chifukwa chake, mphamvu ya inertia ndi ma inertia awiri omwe amapangidwa panthawi ya opareshoni amayambitsa kugwedezeka kwamphamvu ndi kugwedezeka kwa chimbalangondo, kuwononga kukhazikika kwa magwiridwe antchito ndi magawo ena, ndikupanga kugwedezeka kwapang'onopang'ono. Pamene kubala kugwedera pafupipafupi wa kugwedera chophimba exciter ndi ofanana ndi masoka pafupipafupi siteji ya zotanuka kugwedera wa zida chophimba bokosi, izo zichititsa kugwedera amphamvu ya chophimba bokosi elastomer kugwedera chophimba.
Ma drive shaft onse ndi ma shaft shaft oyendetsa amakhala ndi ma frequency a resonance amtengo wina. Ngati ma frequency osangalatsa ali pafupi ndi ma frequency a resonance, resonance imachitika. Kuphatikiza apo, chifukwa cha kukhalapo kwa mphamvu ya centrifugal inertial mu eccentricity, kugwedezeka kopindika kudzachitika. Ngati liwiro liri pafupi ndi mtengo wofunikira, kupindika kwa resonance kudzachitika.
2, Ma radial chilolezo cha kubala
Zotsatira zoyeserera za shale shaker zikuwonetsa kuti kutsitsa kwakung'ono kapena kwakukulu kwambiri kumayambitsa kugwedezeka kwakukulu kwa dongosolo lonyamula. Pamene chilolezo cha radial chili chochepa kwambiri, chimayambitsa kugwedezeka kwakukulu; Pamene chilolezo cha radial ndi chachikulu kwambiri, chimayambitsa kugwedezeka kwafupipafupi.
Ngati chiwongolero cha ma radial ndi chachikulu kwambiri, ma radiation achilengedwe amtundu wa zotanuka adzachepetsedwa, ndipo resonance imachitika mosavuta, yomwe imatulutsa kugwedezeka kwakukulu kocheperako. Chifukwa chake, chilolezo cha radial ndi chachikulu, chomwe chimapangitsa kugwedeza kugwedezeka mu passband.
3, kulondola kwa geometric kwa kubala
Ngati mphamvu yosangalatsa ya chinsalu chogwedezeka ndi yayikulu kwambiri, bearing idzakhala ndi mphamvu yayikulu kwambiri ya radial, kotero kugwedezeka kwamphamvu kumachitika. Pamene msewu wothamanga, makamaka kugwedezeka pamwamba pa chinthu chozungulira, kumakhudza kwambiri kugwedezeka kwa bearing, mayendedwe ogwirizana pakati pa chinthu chozungulira ndi khola ndi pamwamba pa mphete zamkati ndi zakunja zidzayambitsa kugwedezeka kwa bearing. Chifukwa chake, kuti muchepetse kugwedezeka kwa bearing, kulondola kwa kukonza pamwamba pa chinthu chozungulira kuyenera kukonzedwa kaye.
4, Kunyamula mikangano ndi mafuta
Kubereka ndiye gwero lalikulu la kugwedezeka komwe kumakhala kovuta kuwongolera kwa shale shaker. Popeza shale shaker imagwira ntchito ndi mphamvu yayikulu yosangalatsa, chonyamulacho chidzavutika ndi mphamvu yayikulu yozungulira. Ngati mafutawa ndi osauka, padzakhala kukangana kwakukulu, komwe kumapangitsa kutentha kwa kutentha kukwera mofulumira kwambiri komanso kukwera kwambiri, ndi kuwonjezereka kwa kutentha kwakukulu, komwe kumachepetsa kwambiri kutulutsa kwa radial, ndiyeno kuonjezera kukangana, komwe kumawonjezera kutentha.
5. Kuyika mphete yakunja ndi dzenje lothandizira
Ngati kukwanira kuli kolimba, kukakamiza njira yothamanga kuti iwonongeke, kukulitsa cholakwika cha mawonekedwe, ndikupangitsa kugwedezeka kwakukulu. Kusakaniza kotayirira kungayambitse filimu yamafuta yomwe ili pachilolezo kuti itseke. Pamene zinthu zakuthupi za mabowo othandizira a mphete yakunja ndi mpando wonyamulira ndizosiyana kwambiri, makamaka pamene mphete zowonongeka za mphira zimayikidwa pakati pawo, kufalikira kwa vibration kudzaletsedwa.
