Miyezo Yoyang'anira ndi Njira Zopangira Zida Zamakampani
1.1 Dimensional kulondola kwazinthu zomalizidwa
Kulondola kwazithunzi ndi chimodzi mwazinthu zazikulu zowunikira zinthu zomwe zamalizidwa, mizere yotsekera yotsekeka komanso yozungulira yocheperako ndiyofunikira, motero pakati ndi m'mimba mwake mwazozungulira zimapezedwa pomaliza.Pakulondola kwatsatanetsatane kwa mphete zamkati ndi zakunja za zinthu zomalizidwa, sizingakhudze kokha kutulutsa kwamkati kwamkati kwa bearing, komanso magwiridwe antchito a wolandirayo, komanso moyo wautumiki wa faniyo.
1.2 Kuzungulira kolondola kwazinthu zomalizidwa
Kuzungulira kolondola ndichinthu chofunikira kwambiri pakuwunika kwa zinthu zomwe zatsirizidwa.Panthawi yoyika zinthu zomalizidwa, kuthamangitsidwa kwa ma radial pamalo olumikizirana ndi zida zoyikirako kumatha kuthetsedwa molumikizana, motero kuwongolera kuyika kwa magawo oterowo kumathandizira kwambiri.Chifukwa chake, pali chofunikira kwambiri pakuwongolera kozungulira kozungulira.Pakalipano, makina obowola bwino a makina obowola a jig, kulondola kwa nkhwangwa zamagudumu zopukutira bwino, komanso mizere yoziziritsa kuzizira zonse ndizogwirizana kwambiri ndi kusinthasintha kozungulira.
1.3 Radial mkati chilolezo cha zomalizidwa zonyamula katundu
Radial internal clearance ndiye chizindikiro chachikulu chowunikira zinthu zomalizidwa.Popeza ma bearings ali ndi zolinga zosiyanasiyana, chilolezo chamkati chomwe chasankhidwa chimasiyananso kwambiri.Chifukwa chake, panthawi yopanga mafakitale amakono, chilolezo chamkati chamkati chazinthu zomalizidwa chagwiritsidwa ntchito kwambiri ngati chizindikiritso cha muyezo wowongolera, kuyang'anira ndi kuyang'anira zinthu zomalizidwa ndi magawo ena.Chifukwa chake zitha kuwoneka kuti, kuyang'anira chilolezo chamkati ndi chinthu chofunikira pakuwunika zinthu zomaliza zonyamula.
1.4 Kusinthasintha kozungulira ndi phokoso la kugwedezeka kwa zinthu zomaliza zonyamula
Popeza kunyamula kumayang'aniridwa ndi kupsinjika ndi kupsinjika panthawi yogwira ntchito, ndiye kuti pali mawonekedwe apamwamba komanso olimba, malire otanuka kwambiri komanso zofunikira zamphamvu zophatikizika pazomaliza.Chifukwa chake, pakuzungulira, kubereka kwabwino kuyenera kugwira ntchito mwachangu popanda kutsekeka.Kuti muwongolere bwino phokoso la kugwedezeka kwa chotengera, miyeso yofananira iyenera kuchitidwa pakugwedezeka kwa phokoso lochokera pakuyika kolakwika.
1.5 Kuchuluka kwa maginito otsalira azinthu zomalizidwa
Kuchuluka kwa maginito otsalira ndi chimodzi mwazinthu zowunikira zinthu zomwe zatsirizidwa chifukwa pangakhale maginito otsalira panthawi ya opareshoni.Izi ndichifukwa choti ma electromagnetic cores awiri sadzalumikizidwa, chifukwa chake azigwira ntchito pawokha.Pakadali pano, pachimake cha koyilo yamagetsi amatengedwa ngati gawo la makina, pomwe koyiloyo siili.
1.6 Mawonekedwe apamwamba azinthu zomalizidwa
Ubwino wapamtunda ndi chimodzi mwazinthu zowunikira zinthu zomalizidwa, chifukwa chake, kuwunika kofananirako kudzachitika pokhudzana ndi roughness, ming'alu yosiyanasiyana, kuvulala kwamakina ndi mtundu, ndi zina zambiri. koma adzabwezeredwa kwa wopanga kuti akonzenso.Akagwiritsidwa ntchito, amatha kuvulaza makina ambiri pazida.
1.7 Kuuma kwa zinthu zomaliza zonyamula
Kuuma kwa kubereka ndi chizindikiro chachikulu cha khalidwe.Popeza mpira wachitsulo umazungulira mumsewu wozungulira, umakhalanso ndi zotsatira zina zapakati panthawi imodzimodzi, choncho, zitsulo zokhala ndi kuuma kosagwirizana sizidzagwiritsidwa ntchito.
2.1 Njira yachikhalidwe
Njira yoyendera yomalizidwa yomalizidwa ndi njira yowunikira pamanja, pomwe, momwe magwiridwe antchito amkati mwa zida zamakina angayesedwe mozama ndi ogwira ntchito odziwa kugwira ntchito ndi manja kapena kumvetsera ndi makutu.Komabe, ndikukula kwachangu kwamakampani opanga mafakitale masiku ano, pali zolakwika zambiri pakugwiritsa ntchito njira zachikhalidwe, ndipo pakadali pano, zolakwikazo sizingachotsedwe bwino munthawi yake m'njira yamanja.Chifukwa chake, njira yamwambo yakhala ikugwiritsidwa ntchito kawirikawiri masiku ano.
2.2 Njira yowunikira kutentha
Njira yowunikira kutentha kwa ma bearings ndi njira yogwiritsira ntchito zida zotengera kutentha kuti zitsimikizire zolondola za moyo wautumiki wa ma bearings ndikuwongolera zolakwikazo.Kutentha kuyendera mayendedwe ndi tcheru kwambiri kusintha katundu, liwiro ndi kondomu, etc. wa mayendedwe, ndipo makamaka ntchito kasinthasintha mbali ya zida makina, kusewera mbali yaikulu ya kubala, fixation ndi kondomu.Choncho, njira yoyendera kutentha ndi imodzi mwa njira zofala.
2.3 Njira yoyendera ma acoustic emission
The mayendedwe akanakhala kutopa ndi kulephera pambuyo nthawi yaitali ntchito, amene akuwonetseredwa ndi maenje pa kubala kukhudzana pamwamba.Njira yowunikira ma acoustic emission ndikuwunika momwe zinthu zamalizidwira potolera ma sign awa.Njirayi ili ndi zabwino zambiri monga nthawi yochepa yoyankha ku siginecha yotulutsa mawu, kuwonetsa zolephera mwachangu, kuwonetsa nthawi yeniyeni ndikuyika malo olakwika, ndi zina zambiri, chifukwa chake, ukadaulo wa acoustic emission wagwiritsidwa ntchito kwambiri poyang'anira mayendedwe.
2.4 Njira yowunikira kuthamanga kwa mafunde
Pressure wave inspection njira ndi njira yofunika kwambiri yodziwira zolakwika zomwe zidatsirizidwa.Panthawi ya opaleshoniyo, popeza njanji ya mpira, khola ndi mbali zina za zitsulo zimagwidwa ndi abrasion nthawi zonse, choncho, zakhala njira yoyendera yodziwika bwino polandira chizindikiro cha kusinthasintha kuti tifufuze ndikuweruza izi.
2.5 Ukadaulo wozindikira ma vibration
Munthawi yogwira ntchito, chizindikiro cha kugunda kwanthawi ndi nthawi ndiye chinsinsi chowunikira ma bearings pogwiritsa ntchito ukadaulo wozindikira ma vibration.Ming'alu ya zimbalangondo makamaka chifukwa cha ngozi zobisika ku processing osauka, kumene, pa ntchito ndi mkulu mwamphamvu, madera opanda chilema adzakhala ndi ming'alu ndipo ngakhale fracture, motero kutha kwa mayendedwe.Kulakwitsa kwa zinthu zomaliza zonyamula kumayesedwa ndi kulandira ndi kusanthula chizindikiro.Ndikosavuta kugwiritsa ntchito njirayi poyang'anira kuyika ndi kuyika zida, chifukwa chake, iyi ndi imodzi mwa njira zodziwika bwino zowunikira zinthu zomalizidwa.
3.1 Zinthu zowunikira zabwino
Popeza ma bearings ndi amitundu yambiri komanso zolinga zosiyana kwambiri, ndipo khalidwe lililonse limakhalanso ndi zofunikira zosiyana pamayendedwe osiyanasiyana, choncho, zimakhala zofunikira kwambiri kuti pakhale kukonzedwa bwino kwa ntchito zowunikira zinthu zomwe zatsirizidwa.Monga tonse tikudziwa, kuyesa kogwira ntchito komweko ndi kwa mayeso owononga, chifukwa chake, pangakhale kuwonongeka kwina kwa ma bearings popanga kuyendera komwe kukubwera, kuyang'anira ntchito ndikuwunika kwazinthu zomalizidwa.Popanga chiwembu choyendera zasayansi komanso zogwira mtima, kupanga kufunikira kwaubwino wa chinthu china, ndikukhazikitsa muyeso wolondola, zofunikira zolondola komanso mtengo woyezera wa chinthu choyang'aniridwa ziyenera kuganiziridwa makamaka.Zitha kudziwika kuchokera ku chiphunzitso choyambirira cha kusanthula kwa ma siginecha kuti, chizindikiro cha kugwedezeka chiyenera kukhala ndi chizindikiro cha nthawi komanso chizindikiritso cha ma frequency domain, komanso chikoka cha kukonza ndi njira zosiyanasiyana pamikhalidwe yosiyanasiyana yazinthu ziyeneranso kumveka.
3.2 Njira zowunikira bwino
Pankhani yachitukuko ndi zofunikira zamakampani onyamula katundu ku China pakadali pano, njira zingapo zowunikira zimafunikira kuti musankhe chiwembu choyenera kuchokera pamadongosolo ambiri otheka.Papepalali, zinthu zowunikira zinthu zomalizidwa bwino zimafotokozedwa mwatsatanetsatane, kuphatikiza njira zowunikira, zinthu zowunikira komanso njira zowunikira.Zofunikira pakukula kwamakampani onyamula katundu ku China zitha kukwaniritsidwa pokhapokha pakulemeretsa komanso kusinthidwa kosalekeza.
Chifukwa cha chitukuko chofulumira cha sayansi ndi luso lazopangapanga komanso momwe moyo wa anthu ukukulirakulira ku China, pali mitundu yosiyanasiyana ya makina omwe ali ndi moyo wa anthu, omwe amagwira ntchito yofunika kwambiri.Ubwino wa ma bearings ukhoza kutsimikiziridwa ngati kulongedza kwa ma bearings akale ku fakitale kuli bwino.Popeza kunyamula kumagwiritsidwa ntchito makamaka ngati gawo la makina othandizira nsonga yozungulira, chifukwa chake, panthawi yogwira ntchito, imanyamula katundu wa radial ndi axial kuchokera kumtunda, ndikuzungulira ndi axis pa liwiro lalikulu.Pakali pano, pali njira ziwiri zoyendera zomalizidwa ndi zinthu: kuyendera ndi kuyesa zitsanzo.Njira zoweruzira ndizosiyana malinga ndi momwe makina amagwirira ntchito, kufunikira ndi nthawi yoyendera, ndi zina. Zinthu zowunikira zinthu zomwe zimapangidwa makamaka zimatsimikiziridwa molingana ndi mawonekedwe amtundu, koma chilichonse chimakhala ndi mawonekedwe abwino pazinthu zingapo.Kuti apereke kusewera kwakukulu pakuchita bwino kwa mayendedwe, ma bearings amawunikiridwa pafupipafupi ngati njira yodzitetezera.
