Nyob rau hauv lub complex ecosystem ntawm industrial machinery, lub lubrication system yog feem ntau kho raws li ib tug afterthought-kom txog rau thaum nws ua tsis tau tejyam. Thaum tus kws kho tsheb lossis tus tsim lub tshuab zoo li hloov lub twj tso kua mis tsis ua haujlwm lossis tsim lub tshuab hluav taws xob tshiab, lawv tau tsoo lub phab ntsa ntawm cov lus qhia. Qhov tseem ceeb tshaj plaws, tab sis feem ntau tsis to taub, qhov sib txawv hauv daim teb no yog qhov txawv ntawm Resistive Lubrication Systems thiab Volumetric (PDI) Lubrication Systems.
Ntawm Ishan Precision, peb tau txais kev nug txhua hnub los ntawm cov neeg siv khoom tsis meej pem los ntawm ob lub thev naus laus zis no. Lawv nug seb lawv puas tuaj yeem hloov lub twj tso kua mis Showa rau tus qauv Ishan, lossis yog vim li cas lawv lub twj tso kua mis tshiab tsis tsim lub siab ntawm lub tshuab qub. Cov lus teb yuav luag ib txwm nyob hauv kev txheeb xyuas qhov system hom. Tsis meej pem ob lub tshuab no tsis yog ib qho kev ua yuam kev me xwb; nws yog qhov yuam kev loj heev uas tuaj yeem ua rau cov bearings qhuav, scorched slideways, thiab ntau txhiab nyiaj hauv kev kho spindle.
Phau ntawv qhia no yog sau rau cov tuam txhab siv tshuab, cov kws kho mob, thiab cov tswv khw. Peb yuav tshem tawm cov kev lag luam fluff thiab dhia tob rau hauv cov dej dynamics thiab engineering cov hauv paus ntsiab lus uas cais cov resistive thiab volumetric systems, pab koj xaiv txoj cai rau koj machinery.
Kev tsis sib haum xeeb tseem ceeb: Nruam Nruam vs. Kev ntsuas txhaj tshuaj
Txhawm rau kom nkag siab qhov txawv, peb yuav tsum xub saib lub tswv yim tom qab txhua tus qauv tsim. Ob lub tshuab tsom ua ib yam: xa cov roj los ntawm lub hauv paus reservoir mus rau ntau qhov sib txhuam cov ntsiab lus (cov kabmob, pob ntsia hlau, cov lus qhia tawm). Txawm li cas los xij, txoj kev xa khoom yog txawv heev.
Lub Resistive System ua zoo li lub vaj hose nrog ntau lub qhov punched hauv nws. Cov dej (roj) ntws tsis tu ncua raws li ntev raws li tus kais dej (tswj) nyob rau. Qhov loj ntawm lub qhov txiav txim siab npaum li cas dej tawm ntawm txhua qhov chaw. Nws tso siab rau cov dej tsis kam.
Volumetric System, feem ntau hu ua Positive Displacement Injector (PDI) system, ua ntau yam zoo li lub koob txhaj tshuaj. Nws tsis muaj teeb meem ntev npaum li cas lub twj tso kua mis yog nyob rau; lub kaw lus xa ib qho tshwj xeeb, ua ntej - ntsuas koob tshuaj roj- "shot"- thiab tom qab ntawd nres. Nws tso siab rau piston txav.
Kev sib xyaw cov khoom no yog qhov ua rau tuag taus. Yog hais tias koj muab lub twj tso kua mis resistive rau ntawm lub kaw lus volumetric, lub pistons yuav tsis recharge. Yog tias koj muab lub twj tso kua mis ntim rau ntawm lub cev muaj zog, cov roj yuav ntws mus tsis tau.
Deep Dive: Lub Resistive Lubrication System
Lub zog tiv thaiv yog lub zog ua haujlwm ntawm lub teeb - mus rau - nruab nrab CNC kev lag luam. Koj yuav pom nws ntawm feem ntau ntawm cov qauv ntsug machining chaw, lathes, thiab grinders tsim nyob rau hauv Asia. Nws cov koob meej tshwm sim los ntawm nws qhov yooj yim thiab tus nqi- ua tau zoo.
Hauv kev teeb tsa kev tiv thaiv, cov ntsuas ntsuas li qub (feem ntau hu ua distributors lossis junctions) yog qhov tseem ceeb txwv. Lawv muaj ib tug me me orifice los yog ib tug ntxeem tau pas nrig ntxig uas tsim kev tiv thaiv rau cov roj ntws. Qhov kev txwv nruj dua, cov roj tsawg dhau los. Cov li qub no tau categorized los ntawm "Flow Numbers" feem ntau cim li #0, #1, #2, #3, thiab lwm yam. Lub # 3 valve tso cai rau cov roj ntau dua li # 0 valve.
Lub twj tso kua mis nyob rau hauv ib tug resistive system khiav ntawm ib tug yooj yim timer. Nws tig rau, pressurizes txoj kab, thiab roj thawb los ntawm tag nrho cov txwv ib txhij. Lub siab nyob rau hauv lub kaw lus yog txiav txim los ntawm tag nrho cov tsis kam ntawm tag nrho cov li qub ua ke tiv thaiv cov zis muaj peev xwm ntawm lub twj tso kua mis.
Txawm li cas los xij, cov txheej txheem tiv thaiv muaj Achilles lub pob taws: Viscosity. Vim tias nws tso siab rau ntws los ntawm lub qhov me me, cov roj xa tawm hloov pauv nrog qhov kub thiab txias. Nyob rau lub caij ntuj no txias thaum sawv ntxov, cov roj yog tuab, thiab ntws yog txo. Nyob rau yav tav su kub, cov roj thins tawm, thiab ntws nce. Tsis tas li ntawd, vim tias nws yog "txoj kev ntawm qhov tsis muaj zog" qhov system, yog tias txoj kab tseem ceeb tawg nyob ze ntawm lub twj tso kua mis, cov roj yuav tawm mus yooj yim, thiab cov bearings nyob deb ntawm qhov kawg ntawm kab yuav tshaib plab. Qhov no yog vim li cas kev saib xyuas siab yog qhov tseem ceeb hauv cov ntawv thov kev tiv thaiv.
Deep Dive: Volumetric (PDI) Lubrication System
Lub Volumetric lossis PDI system yog qhov ntsuas qhov tseeb ntawm lub ntiaj teb lubrication. Nws hais txog qhov tsis zoo ntawm lub cev tiv thaiv los ntawm kev ua kom ntseeg tau tias txhua qhov lubrication point tau txais cov roj npaum li cas, tsis hais qhov kub, roj viscosity, lossis lub raj ntev.
Cov khoom tseem ceeb ntawm no yog Piston Distributor. Nyob rau hauv txhua tus distributor yog ib tug me me piston thiab lub caij nplooj ntoos hlav. Thaum lub twj tso kua mis tig rau thiab nias rau txoj kab, lub siab yuam kom lub piston txav mus, thawb cov roj ntsuas (piv txwv li, 0.1cc lossis 0.2cc) rau hauv cov kabmob.
Ntawm no yog qhov tseem ceeb: Thaum lub piston tau txav mus thiab tso nws cov roj txhaj tshuaj, nws nyob ntawd. Nws zoo thaiv kab. Tsis muaj roj ntxiv yuav ntws, txawm tias lub twj tso kua mis tseem khiav. Rau qhov system ua haujlwm dua, lub siab nyob rau hauv kab tseem ceeb yuav tsum poob mus rau xoom. Thaum lub siab txo qis, lub caij nplooj ntoos hlav hauv lub distributor thawb lub piston rov qab mus rau nws qhov chaw pib, tso cai rau lub chamber rov qab nrog roj rau lub voj voog tom ntej.
Qhov kev xav tau no tsim ib qho kev thov tshwj xeeb ntawm lub twj tso kua mis. Lub twj tso kua mis tsim los rau lub kaw lus ntim yuav tsum muaj lub Decompression Valve (lossis Siab nyem Valve) ua rau hauv nws. Thaum lub tshuab twj tso kua mis nres, lub valve no qhib kom tso cov kab siab rov qab rau hauv lub tank. Yog tias koj siv lub twj tso kua mis txheem yam tsis muaj qhov decompression feature, lub siab yuav nyob twj ywm hauv kab, lub pistons yuav tsis rov pib dua, thiab koj lub tshuab yuav qhuav tom qab thawj lub voj voog.
Yuav txheeb xyuas qhov system koj muaj li cas
Yog tias koj tab tom sawv ntsug ntawm lub tshuab sim xaj kom hloov lub twj tso kua mis lossis tus xa khoom, koj yuav tsum txheeb xyuas qhov system tam sim ntawd. Ntawm no yog cov duab cues nrhiav.
Ua ntej, saib cov blocks faib. Resistive distributors feem ntau yog tooj dag los yog zinc blocks nrog cov lej cim rau lawv xws li "ST," "SS," "MAS," lossis ib tus lej xws li "0," "1," "2." Lawv yog cov khoom zoo li qub uas tsis muaj qhov txav.
Volumetric distributors saib txawv. Lawv feem ntau siab dua thiab muaj qhov txawv "cap" lossis lub tog raj kheej zoo nyob hauv lub piston. Koj yuav pom cov cim uas qhia qhov ntim, xws li "0.1," "0.2," "0.3," lossis "0.03 cc/st." Qhov "cc/st" sawv cev rau cubic centimeters ib stroke, uas yog tus cim tseem ceeb ntawm PDI system.
Qhov thib ob, mloog lub tshuab. Lub zog tiv thaiv feem ntau khiav lub twj tso kua mis rau lub sijhawm teem sijhawm (xws li, 15 vib nas this) thiab lub siab tuav lub sijhawm ntawd. Lub kaw lus volumetric feem ntau muaj luv luv "mulse." Tej zaum koj yuav pom qhov ntsuas qhov ntsuas siab nrawm mus rau 15-20 kgf / cm2 thiab tom qab ntawd poob qis thaum lub twj tso kua mis tig tawm. Qhov kev poob sai no yog theem decompression, lub plawv dhia ntawm PDI system.
Qhov cuam tshuam ntawm kev xaiv lub twj tso kua mis ntawm qhov System Longevity
Ntawm Ishan Precision, peb tsim cov twj tso kua mis rau ob lub tshuab, tab sis lawv tsis hloov pauv. Peb YET-A thiab YET-C series feem ntau yog teeb tsa rau cov tshuab tiv thaiv, muab cov roj ntws tsis tu ncua. Peb YET-R thiab YET-P series tau tsim tshwj xeeb rau cov tshuab ntim khoom.
YET-R series muaj cov txheej txheem tshwj xeeb uas ua kom lub siab nyem valve lub sijhawm lub cev muaj zog nres. Qhov no ua kom ntseeg tau tias qhov seem siab nyob hauv kab tseem ceeb poob mus rau zero yuav luag tam sim ntawd. Peb tau pom ntau qhov xwm txheej uas ib tus neeg yuav khoom pheej yig dua, cov twj tso kua mis hauv online uas tsis muaj qhov tshwj xeeb no. Lawv nruab rau ntawm PDI - tshuab nruab, thiab ib lub lim tiam tom qab, lawv cov kab ntawv qhia raug puas tsuaj. Lub twj tso kua mis ua haujlwm, nws ua kom siab, tab sis nws yeej tsis cia lub kaw lus "ua pa" kom rov pib dua lub pistons.
Vim li cas Volumetric Systems Yeej Yeej Hauv Kev Lag Luam hnyav
Thaum lub tshuab hluav taws xob tswj hwm lub tshuab me me ua lag luam vim tus nqi, lub tshuab ntim khoom tau dhau los ua tus qauv rau kev lag luam hnyav, loj gantry, thiab cov kab hloov. Qhov laj thawj yog kev ntseeg siab tshaj qhov deb.
Xav txog lub tshuab loj gantry milling qhov twg qhov deb tshaj plaws yog 10 meters deb ntawm lub twj tso kua mis. Nyob rau hauv ib tug resistive system, kev sib txhuam nyob rau hauv uas 10 meters ntawm tubing txo tus nqi txaus. Cov kabmob ze ntawm lub twj tso kua mis tau roj ntau dhau, thiab cov kabmob deb tau tsawg dhau.
Lub volumetric system daws qhov teeb meem physics. Lub siab nthwv dej hla tag nrho 10-meter kab. Ntev npaum li lub kaw lus nce mus txog qhov ntsuas siab (feem ntau nyob ib puag ncig 12 kgf / cm2), lub piston ntawm qhov kawg yuav tua tau tib yam 0.2cc roj raws li lub piston sab xis ntawm lub twj tso kua mis. Qhov "kev hloov pauv zoo" no tau lees paub tias qhov tseem ceeb ntawm kev thauj khoom- cov ntsiab lus bearing yeej tsis nyob hauv-lubricated, ua rau PDI systems tseem ceeb rau cov khoom kim heev, siab load.
Cov lus qhia daws teeb meem rau Txhua Qhov System
Kev kuaj mob tsis ua hauj lwm yuav tsum muaj kev xav sib txawv rau txhua hom kab ke.
Thaum teeb meem kev tiv thaiv qhov system, koj tab tom nrhiav kev ntws. Yog tias lub siab tsis tshua muaj, nrhiav kev tawm. Yog hais tias lub siab yog siab, nrhiav ib qho thaiv los yog ib txoj kab crushed. Ib qho teeb meem tshwm sim yog qhov teeb meem "txoj kev ntawm qhov tsis zoo"-yog tias ib lub ntsuas ntsuas valve poob los yog ib txoj kab tawg, lub siab poob mus rau xoom txhua qhov chaw, thiab tag nrho lub tshuab tsis muaj kev tiv thaiv.
Thaum daws teeb meem ntawm qhov system volumetric, koj tab tom nrhiav rau lub voj voog rov pib dua. Qhov feem ntau tsis ua hauj lwm yog qhov yuam kev "Pressure Switch On" , txhais tau hais tias lub kaw lus ua tsis tiav rau kev ntxhov siab. Qhov no taw qhia rau lub pob nyem nyem valve hauv lub twj tso kua mis lossis siv cov roj uas tuab heev (siab viscosity) kom ntws rov qab sai thaum huab cua txias. Lwm qhov teeb meem tshwm sim yog ib qho thaiv tus xa khoom. Tsis zoo li cov txheej txheem tiv thaiv, yog tias ib lub piston ntes tau, qhov seem ntawm lub kaw lus feem ntau tseem ua haujlwm, uas yog qhov muaj kev nyab xeeb, tab sis nws txhais tau tias koj yuav tsum tshuaj xyuas cov ntsiab lus lubrication ntawm tus kheej kom ntseeg tau tias lawv ntub.
Hloov Hloov Ntawm Cov Txheej Txheem: Puas Yog Ua Tau?
Peb feem ntau nug yog tias lub tshuab tuaj yeem hloov pauv los ntawm kev tiv thaiv mus rau volumetric lossis rov ua dua. Cov lus teb luv luv yog yog, tab sis nws yuav tsum tau kho kom tiav. Koj tsis tuaj yeem hloov lub twj tso kua mis xwb. Koj yuav tsum hloov txhua qhov ntsuas qhov ntsuas thiab qhov sib txuas ntawm lub tshuab.
Kev kho dua tshiab rau lub kaw lus ntim yog qhov nrov retrofit rau cov tshuab qub uas raug kev txom nyem los ntawm kev hnav. Los ntawm kev txhim kho PDI distributors thiab lub twj tso kua mis Ishan sib haum nrog decompression, koj tuaj yeem rov qab tswj lub lubrication zoo thiab nres qhov "stick-slip" cov lus tsa suab uas ua rau lub ntsej muag ua tiav. Nws yog kev nqis peev, tab sis piv rau tus nqi ntawm kev khawb thiab rov tsim kho lub thawv, nws yog ib qho kev sib tham.
