Raws li daim ntawv thov kev txwv - hom hydraulic coupler ntawm ob lub - toothed roller crusher, daim ntawv no txheeb xyuas qhov ua tsis tiav ntawm qhov txwv - hom coupler vim muaj kev cuam tshuam kev thauj khoom thiab muab tso rau hauv kev daws teeb meem. Qhov teeb meem ntawm lub coupler hauvmineral sizersyog daws tau zoo thiab kev ua haujlwm zoo ntawm cov cuab yeej siv tau zoo dua.
1 Lub sijhawm txwv cov kua dej sib txuas hauv cov dej ntxhia hauv cov dej ntxhia Daim ntawv thov qhov xwm txheej Txwv lub sijhawm cov kua dej sib txuas hauv qab no hu ua "coupling" yog hom tsis yog -rigid coupling nrog cov kua ua haujlwm nruab nrab, vim tias nws tuaj yeem ua rau lub cev muaj zog pib, txo qhov cuam tshuam thiab kev co thaum lub sijhawm pib lub cev muaj zog, nrog kev tiv thaiv ntau dhau. Nws muaj ntau yam zoo xws li kev sib cais ntawm kev poob siab thiab torsional vibration thiab tau siv ntau thiab ntau dua. Lub taub hau ntawm 2 lab tons ntawm lub tsev cov ntaub ntawv ntau lawm kab ntawm peb lub tuam txhab yog kev cob cog rua los ntawm ib tug coupling ntawm lub cev muaj zog YKK400 thiab lub reducer, thiab cov coupling hom yog TVA562. Tsis ntev tom qab cov kab ntau lawm steel tau muab tso rau hauv kev ua haujlwm, cov kev sib txuas tau tawg ntau zaus, uas cuam tshuam rau cov khoom ib txwm muaj. Vim tias cov kab ntau lawm siv lub khoos phis tawj sab saud (lub computer thiab PLC centralized tswj hom, lub khoos phis tawj tuaj yeem sau cia, khaws lub cev muaj zog tam sim no, qhov hluav taws xob thiab lwm yam ntaub ntawv khiav haujlwm, thiab tso saib hauv yoj nkhaus. Yog li ntawd, raws li cov lus qhia xws li tam sim no fluctuation nkhaus ntawm lub siab -voltage motor, peb ua tib zoo txheeb xyuas qhov laj thawj rau qhov tsis ua haujlwm ntawm lub coupler, thiab thaum kawg tau daws tag nrho cov teeb meem uas muaj nyob rau hauv ob peb lub koom haum. cov khoom qub.
Muaj tsib qhov teeb meem tseem ceeb hauv kev siv cov couplings hauv cov pob zeb loj. Kev poob siab kev vibration yog qhov ua rau muaj teeb meem, thiab qhov tsim tsis tsim nyog ntawm cov qauv sib txuas kuj yog ib qho ntawm lawv: Coupler jitter feem ntau tom qab 2 lub hlis ntawm kev siv, lub jitter maj mam nce, ua rau tsis tshua muaj kev puas tsuaj rau cov zis bearing ntawm high voltage lub cev muaj zog thiab bearing ntawm lub input ncej ntawm lub reducer. Cov kabmob ntawm lub tshuab hluav taws xob siab yog hloov ib zaug txhua 2 lub hlis ntawm qhov nruab nrab, thiab cov kabmob ntawm cov khoom siv ntawm lub reducer yuav tsum tau hloov ib zaug txhua 4 lub hlis ntawm qhov nruab nrab. Yog hais tias lub bearing tsis hloov raws sij hawm, thaum lub bearing poob sib nrug, lub input ncej ntawm lub reducer yuav tawg.
