Dalilai da Magani Don Ƙarfin Girgizar Allon Girgizawa
1. Eccentric vibration na exciter
Ƙarfin centrifugal da aka haifar da nauyin eccentric yayin aiki na motsa jiki mai motsi zai lanƙwasa maɗaukakiyar maɗaukaki, yana haifar da jujjuyawar dangi na zobe na ciki da na waje na ɗaukar hoto. Ƙwararren ƙira zai haifar da girgizar da ke haifar da jujjuyawar mitar da mitoci masu jituwa.
Sabili da haka, ƙarfin inertia da ma'auratan inertia da aka haifar yayin aikin za su haifar da ƙarfin amsawa mai ƙarfi da rawar jiki na ɗaukar nauyi, lalata yanayin aiki na barga da sauran sassa, kuma ya haifar da girgiza mai girma. Lokacin da mitar girgiza mai motsi na allo mai jijjiga yayi daidai da mitar yanayi na wani mataki na girgizar akwatin allo na kayan aiki, zai haifar da girgiza mai ƙarfi na akwatin allo elastomer na allon jijjiga.
Duka ɓangarorin faifan tuƙi da tsarin tuƙi na abin ɗamara suna da mitar ƙarar ƙima. Idan wasu mitoci masu ban sha'awa suna kusa da mitar resonance, resonance yana faruwa. Bugu da ƙari, saboda kasancewar ƙarfin inertial na centrifugal a cikin eccentricity, lanƙwasa rawar jiki zai faru. Idan gudun yana kusa da ƙima mai mahimmanci, lanƙwasawa resonance zai faru.
2. Radial barranta na ɗaukar nauyi
Sakamakon gwajin ɗaukar hoto na shale shaker ya nuna cewa ƙarami ko babban sharewar radial zai haifar da girgizar tsarin ɗaukar hoto. Lokacin da izinin radial ya yi ƙanƙanta, zai haifar da girgiza mai girma; Lokacin da izinin radial ya yi girma sosai, zai haifar da ƙaramar girgizawa.
Idan izinin radial ya yi girma da yawa, za a rage mitar radial na tsarin roba mai ɗaukar nauyi, kuma sautin zai iya faruwa cikin sauƙi, wanda zai haifar da ƙaramar ƙaramar girgiza. Saboda haka, ƙyalli na radial yana da girma, wanda ke sa mai ɗaukar hoto ya yi rawar jiki a cikin lambar wucewa.
3. Daidaiton Geometric na ɗauka
Idan ƙarfin ban sha'awa na allon girgiza ya yi yawa, bearing ɗin zai ɗauki babban ƙarfin radial, don haka girgiza mai ƙarfi zai faru. Lokacin da hanyar tsere, musamman raƙuman ruwa a saman abin birgima, ke da tasiri mafi girma akan girgizar bearing, motsin da ke tsakanin abin birgima da keji da kuma saman birgima na zoben ciki da na waje zai haifar da girgizar bearing. Saboda haka, don rage girgizar bearing, ya kamata a fara inganta daidaiton sarrafa saman abin birgima.
4. Ciwon sanyi da lubrication
Bearing shine babban tushen jijjiga wanda ke da wahalar sarrafawa ga mai girgiza shale. Tun da shale shaker yana aiki da babban ƙarfin motsa jiki, ɗaukar nauyi zai sha wahala mai girma na radial. Idan man shafawa bai yi kyau ba, za a sami juzu'i mai yawa, wanda hakan zai sa yanayin zafi ya tashi da sauri da yawa, da haɓakar thermal ɗin da yawa, wanda hakan zai rage tasirin radial sosai, sannan kuma ƙara juzu'i, wanda zai ƙara haɓaka zafi.
5. Fitting na waje zobe da goyon bayan rami
Idan dacewa yana da ƙarfi, zai tilasta titin tseren don lalacewa, ƙara kuskuren siffar, kuma ya haifar da ƙarar girgiza. Ƙunƙarar da ba ta da kyau zai iya haifar da fim din mai a cikin yarda don toshewa. Lokacin da kaddarorin kayan ramuka masu goyan bayan zobe na waje da wurin zama sun bambanta sosai, musamman lokacin da aka sanya zoben damping na roba a tsakanin su, za a hana watsawar girgiza.
