Kho ntawm high-speed centrifuge commutator

Kho ntawm high-speed centrifuge commutator

Txhim kho qhov kawg npog ntawm ob qho kawg ntawm tus kov hluav taws xob. Ua ntej disassembly, ua ib qho cim rau ntawm xya lub hauv qab kawg npog kom lawv tuaj yeem ntsia tau raws li lawv tau kho tom qab kho. Cov bearings ntawm R armature yuav tsum tau ua tib zoo ntxuav. Thaum ntxuav, siv cov roj av huv si. Tom qab cov roj av qhuav, sau cov kabmob chamber nrog 7014 (lossis 7018) cov kabmob roj (cov roj ntsha ib txwm siv lossis molybdenum disulfide tsis tuaj yeem siv rau cov kabmob ntawm cov motors ceev). Muab tso rau hauv qhov chaw huv si rau kev siv; Yog hais tias qhov chaw ntawm lub commutator yog tiaj tus thiab muaj ib tug liab qab luster, qhov no yog ib tug oxide txheej uas yuav tiv thaiv lub nto ntawm lub commutator. Siv txhuam txhuam kom tshem tawm cov hmoov av

Khiav-hauv ntawm Armature

Nruab lub armature thiab carbon txhuam nyob rau hauv qhov kev txiav txim rov qab ntawm disassembly, maj mam txav lub commutator ntawm tes, thiab manually grind nyob rau hauv cov pa roj carbon txhuam. Ua ntej, grind lub commutator raws li txoj kev hauv (1). Tom qab ntawd, lub hwj chim rau thiab khiav hauv. Qhov kev khiav hauv cov txheej txheem yog raws li nram no: ua ntej, khiav ntawm 5000 RPM yam tsis muaj load rau 10 teev. Yog tias pom muaj lub txim loj thaum lub sijhawm ua haujlwm, nres qhov khiav hauv. Yog tias tsis muaj lub txim taws, theem ob tuaj yeem siv tau ntawm 10 000 RPH rau 4 teev. Tom qab txhua yam zoo li qub, theem peb tuaj yeem nkag mus. Qhov thib peb theem yog 2500 RPM nrog load. Yog tias siv lub centrifuge siab ceev rau kev thauj khoom khiav-hauv, qhov taw qhia ntawm lub centrifuge's tachometer tuaj yeem siv tau raws li qhov tseeb khiav-hauv. Txawm li cas los xij, nws yog ib qho tsim nyog yuav tsum siv lub taub hau centrifuge nrog lub siab tshaj plaws ceev rau lub teeb load. Yog tias siv lub centrifuge ultra high-speed centrifuge rau kev thauj khoom khiav-hauv, qhov sib txawv ntawm qhov ceev yuav tsum tau kho. Thaum teeb tsa qhov ceev tshaj 80000 r / los nag rau ib qho kev kub ceev centrifuge, me me tig lub taub hau nrog kev ceev dua tuaj yeem siv los ua kom lub nra hnyav dua, Vim tias qhov sib txawv ntawm qhov sib txawv ntawm qhov kub ceev centrifuge yog 4.2: 1, Thaum lub tachometer qhia 10000 rpm, qhov tseeb ceev ntawm lub cev muaj zog yog nyob ib ncig ntawm 2500 r / los nag. Yog tias muaj ob peb lub pob me me los yog ob lossis ntau lub pob zeb loj thaum lub sij hawm tag nrho tsis muaj kev thauj khoom lossis kev thauj khoom khiav-hauv cov txheej txheem plaub, nws tsis tuaj yeem txuas ntxiv, Ntxiv rau kev ua tib zoo xyuas seb lub installation puas tsim nyog, nws tseem yuav tsum tau rov qab los. mus rau yav dhau los khiav hauv cov txheej txheem thiab rov ua haujlwm kom txog thaum nws tsim nyog.

Kho ntawm commutator

(1) Lub commutator yog lub hauv paus tiaj tus, nrog me ntsis khawb lossis sparks. Piv txwv li, nyob rau hauv rooj plaub thib ob, qhov chaw nres nkoj 1 yog manually hauv av nrog dej xuab zeb yam tsis muaj disassembling lub armature. Kev sib tsoo yog raws li hauv qab no: ua ntej, raws li qhov curvature ntawm lub commutator lub sab nrauv lub voj voog, tshuab ib lub cuab yeej ntoo, txiav ob peb thicknesses ntawm cov xuab zeb rau hauv ib lub strips ntev raws li lub commutator, tshem tawm cov pa roj carbon txhuam (thov nco ntsoov kos tus kov. thiab zawj ntawm cov txhuam hniav tshem tawm kom ntseeg tau tias nws tsis hloov sab laug lossis txoj cai tsis raug thaum lub sijhawm teeb tsa), siv cov cuab yeej ntoo qhwv hauv cov ntawv xuab zeb los lo rau lub commutator kom nruj, thiab siv lwm txhais tes los nias cov kev taw qhia ntawm lub cev muaj zog, maj mam tig. tus ncej commutator rau grind. Siv cov ntawv xuab zeb nyob rau hauv qhov kev txiav txim ntawm thickness, thawj coarse thiab ces zoo. Thaum ib daim ntawv xuab zeb dig muag dhau los siv, hloov nws nrog lwm cov ntawv xuab zeb kom txog thaum cov ntawv xuab zeb zoo tshaj plaws (lossis metallographic sandpaper) siv.

(2) Qhov saum npoo ntawm lub commutator yog qhov tsis sib xws (tactile los ntawm tes) lossis sparks tshwm sim thaum lub sijhawm ua haujlwm, raws li tau piav qhia hauv plaub qhov xwm txheej. Hauv qhov no, nws yog ib qho tsim nyog yuav tsum tau disassemble lub armature thiab siv lub tshuab cuab yeej los ua cov commutator. Lub tshuab dhos yuav tsum yog lub tshuab dhos precision,
