Yog tias koj nyob hauv kev ua lag luam rau kev txhim khu kev qha ntsia hlau hom ib-theem compressors-txawm yog rau cov dej zoo drilling, kev tsim khoom, lossis kev tsim kho-koj paub tias qhov tseem ceeb ntawm kev ua tau zoo li cas rau kev ua haujlwm zoo thiab ua haujlwm ntev. Raws li tus neeg muag khoom ntawm cov tshuab no, kuv tau siv ntau xyoo los daws qhov teeb meem dab tsi ua rau qhov sib txawv loj tshaj plaws hauv compressor lub neej ntev, thiab ib qho ntawm feem cuam tshuam, tab sis feem ntau tsis saib xyuas, yam tseem ceeb yog qhov ua tiav ntawm compressor lub rotors. Lub rotor ntxhib los yog tsis zoo tiav tsis yog ua mob rau kev ua haujlwm xwb; nws tuaj yeem ua rau cov nqi hluav taws xob ntau dua, kev tawg tsis tu ncua, thiab txawm tias cov khoom siv luv luv. Niaj hnub no, kuv tab tom rhuav tshem cov kev ua tau zoo, kev tshawb fawb-txhawb txoj hauv kev los txhim kho qhov chaw tiav, yog li koj lub compressor khiav smoother, kav ntev dua, thiab txuag koj cov nyiaj dhau sijhawm.
Ua ntej, cia peb mus rau tib nplooj ntawv: dab tsi yog qhov rotor nto tiav hauv cov ntsia hlau compressor? Cov rotors (txiv neej thiab poj niam) yog lub plawv ntawm chav tsev-lawv mesh ua ke rau ntxiab thiab compress cua thaum lawv tig. Yog tias lawv qhov chaw muaj qhov siab tsis sib xws, hav, lossis cov cuab yeej cim, ob peb teeb meem tshwm sim. Rau ib qho, huab cua xau los ntawm cov qhov khoob, yog li koj lub tshuab compressor yuav tsum tau ua haujlwm hnyav dua los ntaus lub siab xav tau, noj rau hauv lub zog. Qhov thib ob, qhov chaw ntxhib ntes cov roj thiab cov khib nyiab, ua rau muaj kev hnav ntau dua ntawm cov rotors thiab lwm qhov chaw, uas txhais tau tias kev saib xyuas ntau dua thiab cov nqi mus sij hawm ntev dua. Thiab cia peb tsis txhob hnov qab, qhov ua tiav tsis zoo tuaj yeem ua rau cov suab nrov nrov nrov, uas yog qhov tsis muaj qhov loj rau qhov chaw ua haujlwm. Tias yog vim li cas nailing no nthuav dav yog tsis-negotiable yog hais tias koj xav tau ib tug compressor uas muab kev ua tau zoo ib yam.
Tam sim no, cia peb dhia mus rau qhov tseeb, cov kauj ruam ua tau zoo uas peb siv (thiab pom zoo rau peb cov neeg siv khoom) kom tau txais qhov rotor nto tiav lawm. Qhov xwm zoo yog, koj tsis xav tau cov cuab yeej zoo nkauj, tawm ntawm cov cuab yeej-koj tsuas yog yuav tsum ua raws li cov txheej txheem raug thiab ua tib zoo saib xyuas cov ntsiab lus me me ntawm txhua theem ntawm kev tsim khoom.
Ua ntej, qhov sib tsoo theem: qhov no yog qhov feem ntau ntawm qhov pib shaping tshwm sim, thiab nws yog lub hauv paus ntawm qhov kawg nto tiav. Ntau tus neeg muag khoom tau txiav cov ces kaum ntawm no los ntawm kev siv lub tshuab sib tsoo los yog rushing hla dhau, tab sis peb tau pom tias kev nqis peev hauv kev sib tsoo ua rau txhua qhov sib txawv. Qhov tseem ceeb ntawm no yog siv cov khoom siv zoo, pob zeb diamond-tipped sib tsoo lub log (tsis yog tus qauv txhuas oxide ib qho) uas sib phim rau cov khoom siv rotor-feem ntau cov rotors yog tsim los ntawm cov hlau los yog cam khwb cia hlau, yog li lub log yuav tsum muaj zog txaus los txiav cov khoom ntawd yam tsis muaj qhov sib sib zog nqus khawb. Tsis tas li ntawd, qhov sib tsoo pub tus nqi thiab ceev tseem ceeb heev. Yog tias koj thawb lub log nrawm dhau ntawm lub rotor, nws tsim cov ncov tsis sib xws uas peb tau tham txog; siv qeeb heev, thiab koj tau txais cov cua sov uas tuaj yeem ua rau lub rotor ntog (lub tshav kub yog yeeb ncuab ntawm no, los ntawm txoj kev-qhov kub tshaj ua rau cov khoom nthuav dav thiab tuaj yeem tawm hauv qhov kev ntxhov siab, uas cuam tshuam qhov kawg thiab qhov tseeb qhov tseeb). Peb sim peb cov kev sib tsoo tsis zoo, thiab peb tau pom tias lub log ceev ntawm ib ncig ntawm 30-35 m / s nrog tus nqi pub ntawm 0.1-0.2 hli rau ib lub kiv puag ncig muab peb lub hauv paus du uas yog txoj hauv kev yooj yim dua rau tom qab. Rau peb cov neeg xav tau kev xav tau tshwj xeeb los yog kev hloov pauv, qhov kev sib tsoo no ua kom muaj kev sib raug zoo nrog txhua yam ntawm peb.Ua tau zoo Cua compressorqauv rau peb lojLoj-txav Air Compressorkab.
Tom ntej no, qhov tseem ceeb heev (thiab feem ntau hla) ua tiav cov kauj ruam: honing. Tos, kuv paub koj tab tom xav li cas - "tsis sib tsoo txaus?" Tsis yog. Kev sib tsoo tawm cov kab me me uas koj tsis tuaj yeem pom ntawm qhov muag liab qab, tab sis lawv txaus ua rau huab cua ntws thiab hnav dhau sijhawm. Honing siv pob zeb abrasive (feem ntau yog silicone carbide los yog pob zeb diamond) uas txav mus rau hauv tus qauv ntoo khaub lig-hatch thoob plaws lub rotor nto, smoothing tawm cov micro-peaks thiab tawm hauv ib qho chaw, tiaj tus. Qhov ua kom yuam kev ntawm no yog tswj cov honing siab thiab pob zeb grit loj. Peb pib nrog cov ntxhib ntxhib (ib ncig 120-180) kom tshem tawm cov kev sib tsoo tsis zoo, tom qab ntawd txav mus rau nruab nrab grit (280-320) rau ib nrab-theem tiav, thiab thaum kawg ib qho zoo grit (400-600) kom tau qhov super-smooth nto peb xav tau. Yog tias koj hla qhov kev nce qib grit, koj yuav tawm cov pob zeb ntxhib uas tsuas yog tsim teeb meem ntxiv tom qab. Tsis tas li ntawd, lubrication thaum lub sij hawm honing yog qhov tseem ceeb-siv cov roj honing (tsis yog dej) txias lub rotor, tshem tawm cov hlau shavings, thiab tiv thaiv cov pob zeb los ntawm glazing dhau (thaum hlau clogs lub pob zeb lub pores, ua kom nws tsis txhob txiav sib npaug). Cov kauj ruam no yog qhov yuav siv lub rotor los ntawm "zoo txaus" mus rau "ua tau tiag tiag li nws yuav tsum," uas yog vim li cas peb cov qauv zoo liKev txuag hluav taws xob cua CompressorthiabMedium Pressure Dej Zoo Cua Compressorxa qhov ua tau zoo ib yam li peb cov neeg siv khoom ntseeg siab.
Tom qab ntawd muaj cov txheej txheem tom qab ua tiav - qhov no yog qhov tseem ceeb tshaj li cov neeg feem coob paub. Txawm tias ib qho me me ntawm cov hlau shavings, honing roj residue, los yog sib tsoo cov khoom siv sab laug ntawm lub rotor nto tuaj yeem ua rau micro-scratches thaum lub sij hawm sib dhos, los yog muaj kab mob hauv lub tshuab cua compressor. Peb mus los ntawm cov txheej txheem peb-kauj ruam ntawm no: ua ntej, ib lub qhov hnyav da dej kom tshem tawm cov roj hnyav, tom qab ntawd ib qho ultrasonic ntxuav nrog cov tshuaj ntxuav me me kom nkag mus rau hauv cov khoob me me thiab cov cuab yeej cim, thiab thaum kawg yaug nrog dej deionized los tiv thaiv cov pob zeb hauv av, ua raws li huab cua kom qhuav ntawm qhov kub thiab txias (tsis muaj phom cua sov ntawm no - ntau dhau cua sov warps lub rotor). Peb tau muaj cov neeg siv khoom qhia rau peb tias cov neeg muag khoom pheej yig dua hla lub qhov tob tob, thiab tsis pub dhau ob peb lub hlis lawv cov compressor pib tawm cua vim tias cov khib nyiab pov tseg rau hauv lub rotors. Tsis txhob ua yuam kev.
Lwm yam uas tib neeg saib tsis taus yog cov khoom siv rotor thiab kev kho cua sov ua ntej ua tiav. Yog tias koj lub rotor yog ua los ntawm cov qib qis qis uas yog mos heev, txawm tias qhov zoo tshaj plaws kev sib tsoo thiab honing yuav tsis muab rau koj qhov chaw ruaj khov-nws yuav hnav sai sai. Tias yog vim li cas peb siv high-qib alloy steel rau tag nrho peb rotors, thiab peb ua ib rooj plaub hardening tshav kub kev kho mob: uas txhais tau tias peb ntxiv ib tug nyias, nyuaj txheej rau lub rotor nto thaum ua kom cov tub ntxhais tawv txaus los daws kev ntxhov siab. Cov ntaub ntawv hardening kuj ua rau saum npoo tiv taus hnav, yog li txawm tias muaj kev sib cuag me me nrog rau lwm lub rotor (uas yuav tsum tsis muaj, tab sis txawm tias me ntsis yog qhov qub), nws yuav tsis tawm qhov khawb tob. Yog tias koj hla kev kho cua sov kom zoo, qhov ua tiav saum npoo yuav zoo thaum xub thawj, tab sis nws yuav degrade sai, ua rau cov nqi saib xyuas ntau dua rau koj hauv kab.
Tos, ua li cas txog txheej? Puas yog lub tswv yim zoo? Nws nyob ntawm daim ntawv thov, tab sis rau feem ntau cov ntsia hlau compressors, cov txheej nyias nyias tuaj yeem nqa qhov chaw tiav mus rau qib tom ntej. Peb siv lub tshuab ziab khaub ncaws qhuav rau qee qhov ntawm peb cov qauv uas khiav hauv qhov chaw muaj av noo lossis plua plav-cov txheej no tsuas yog ob peb microns tuab, yog li nws tsis hloov lub rotor qhov ntev (uas yog qhov tseem ceeb heev rau meshing), tab sis nws sau rau hauv cov me me me me thiab txo kev sib txhuam. Qhov ntawd txhais tau hais tias hnav tsawg dua, huab cua zoo dua qub, thiab txawm tias siv lub zog qis dua vim tias cov rotors tig tau zoo dua. Qhov tseem ceeb ntawm no yog tias cov txheej yuav tsum tau siv sib npaug - txhua qhov tuab tuab yuav muab pov tawm ntawm lub rotor txoj kev sib dhos thiab ua rau cov dej ntws. Peb ua haujlwm ze nrog peb cov neeg muab txheej txheej kom paub tseeb tias cov txheej txheem thov yog qhov tseeb, thiab peb sim txhua tus txheej txheem coated rotor kom raug qhov tseeb ua ntej nws nkag mus rau hauv compressor.
Tam sim no, cia peb tham txog kev tswj kom zoo-koj tsis tuaj yeem txhim kho qhov chaw tiav yog tias koj ntsuas tsis zoo. Peb siv lub tshuab roughness tester, uas muab peb tus lej (Ra tus nqi) uas qhia peb tias lub ntsej muag du npaum li cas. Rau peb cov rotors, peb tsom rau tus nqi Ra ntawm 0.2 txog 0.4 micrometers-txhua yam siab dua 0.5 yog qhov ntxhib dhau, thiab txhua yam qis dua 0.1 yog qhov tsis tsim nyog (nws tsuas yog ntxiv tus nqi tsis muaj txiaj ntsig kev ua haujlwm tiag tiag). Peb kuj siv ib tug profileometer los xyuas lub rotor profile (yuav ua li cas ncaj thiab uniform lub saum npoo yog raws nws ntev) vim hais tias txawm ib tug zoo kawg nkaus du nto uas yog me ntsis khoov ntawm ib tug taw tes yuav ua rau huab cua to thiab hnav. Txhua lub rotor dhau los ntawm cov kev sim no ua ntej nws tau sib sau ua ke rau hauv compressor, thiab peb khaws cov ntaub ntawv ntawm txhua feem-yog li yog tias tus neeg siv khoom muaj teeb meem, peb tuaj yeem taug qab nws tau ua li cas. Qhov ntawd yog hom kev lav phib xaub uas koj tsis tau txais nrog cov neeg xa khoom random.
Kuv kuj yuav tsum tau hais tias txawm tias tom qab lub compressor tau tsim, kev txhim kho thiab kev kho kom zoo yuav ua kom lub rotor nto tiav lawm. Yog tias koj nruab lub compressor tsis raug, nrog misaligned rotors, uas yuav ua rau lawv txhuam ua ke, khawb qhov saum npoo, thiab ua kom puas tag nrho cov hauj lwm uas koj muab tso rau hauv kom tiav. Kev hloov roj tsis tu ncua (siv hom roj zoo rau koj lub tshuab compressor) thiab kev hloov pauv huab cua kuj tseem tiv thaiv cov khib nyiab kom nkag mus rau hauv lub rotor chamber thiab khawb qhov chaw. Peb ib txwm muab cov lus qhia kev saib xyuas nrog peb cov neeg siv khoom, thiab peb muab kev txhawb nqa yog tias lawv muaj lus nug txog kev teeb tsa lossis kev saib xyuas.
Cia kuv muab qhov no tso rau hauv qhov kev xav rau koj. Ob peb lub hlis dhau los, peb muaj cov neeg siv khoom uas tau siv lub tshuab compressor sib tw, thiab lawv tau pom 20% cov nqi hluav taws xob ntau dua li lawv qhov qub. Lawv tab tom ua haujlwm ntawm qhov dej zoo drilling, yog li lawv xav tau ib lub chaw ruaj ntseg uas tuaj yeem ua haujlwm ntev ntev. Thaum lawv xa lawv cov compressor rau peb kuaj, peb rub tawm cov rotors thiab pom tias qhov chaw tiav yog Ra 1.2 micrometers-super ntxhib, nrog sib sib zog nqus cov cim. Tus neeg sib tw tau txiav cov ces kaum ntawm kev sib tsoo thiab hla lub honing kauj ruam nkaus. Peb hloov lawv cov rotors nrog cov ua tiav rau Ra 0.3 micrometers, siv cov txheej txheem sib tsoo thiab honing uas kuv tau tham txog, thiab teeb tsaHigh Pressure Dej Zoo Cua Compressorlos ntawm peb cov kab uas phim lawv cov kev xav tau hloov chaw. Tsis pub dhau ib hlis, lawv cov nqi hluav taws xob poob los ntawm 18%, thiab lawv tau hais rau peb tias lub compressor khiav ntsiag to nrog tsawg dua kev puas tsuaj. Qhov ntawd yog qhov sib txawv zoo rotor nto tiav ua.
Yog tias koj nyob hauv kev ua lag luam rau cov ntsia hlau hom ib-theem compressor, txawm tias dej zoo ua haujlwm, kev siv hauv tsev, lossis lwm yam kev thov, tsis txhob saib tus nqi tag. Nug txog cov txheej txheem rotor deg tiav-Ra tus nqi lawv xav li cas, kev sib tsoo thiab honing cov kauj ruam lawv siv, thiab seb lawv puas ua kom zoo thiab kho cua sov. Lub compressor nrog lub rotor ua tiav zoo yuav txuag koj nyiaj ntau dua lub sijhawm ntawm cov nqi hluav taws xob thiab kev saib xyuas dua li lub tsev pheej yig dua nrog lub rotor ntxhib.
Peb tau ua tiav peb cov compressor ntau lawm ntau xyoo, thiab peb tsom ntsoov rau txhua yam me me-los ntawm rotor nto tiav rau lub zog ua haujlwm-yog vim li cas peb cov neeg siv khoom rov qab los. Yog tias koj tab tom nrhiav rau lub tshuab compressor uas muab kev ua haujlwm zoo ib yam, siv lub zog qis, thiab ua haujlwm ntev, peb tau txais koj them. Peb tuaj yeem taug kev koj los ntawm peb cov khoom lag luam, los ntawm peb cov qauv ua tau zoo heev rau peb cov chaw xa khoom loj, thiab pab koj nrhiav qhov haum rau koj cov kev xav tau. Hu rau peb los tham txog koj cov kev xav tau thiab tau txais cov lus pom zoo uas ua haujlwm rau koj txoj haujlwm.
