Thaum koj hnov 'cam khwb cia hlau', feem ntau lub siab dhia ncaj nraim mus rau 'hnyav' thiab 'xeb-nrhiav'. Qhov ntawd yog qhov cuab yeej cuab tam. Nyob rau hauv kev xyaum, zaj dab neeg yog hais txog damping peev, thermal stability, thiab nqi-zoo rau tej, feem ntau unforgiving, kev siv. Nws tsis yog ib qho loj-haum-tag nrho cov kev daws teeb meem, thiab nws cov txiaj ntsig tiag yog nkag siab tsuas yog tom qab koj tau pom ob peb qhov ua tsis tiav hauv daim teb lossis ua tiav qhov twg cov ntaub ntawv fancier tuav tsis tau.
Kev nkag siab yuam kev ntawm Materiality
Cia tus ntxhw tawm ntawm chav tsev: yog, nws hnyav. Tab sis qhov hnyav ntawd feem ntau yog qhov taw tes. Rau lub hauv paus thav duab ntawm high-vibration machinery-xav tias cov twj loj los yog compressor vaj tse-qhov loj yog ib qho feature, tsis yog kab laum. Cov cam khwb cia hlau casing ua raws li lub dab dej, absorbing thiab dissipating vibrational zog uas yuav ua rau qaug zog bolts, tawg welds, los yog ruin bearing tolerances nyob rau hauv ib tug sib zog alloy ncej. Kuv tau pom cov vaj tsev nyob ntawm qhov kev sim sawv ntsug ntawm lawv tus kheej sib nrug, thaum lub qub, greasy hlau counterpart ntawm nws cia li hummed nrog.
Kev txhawj xeeb xeb yog siv tau, tab sis overblown nyob rau hauv kev tswj ib puag ncig. Nws yog qhov teeb meem saum npoo, tsis yog feem ntau yog ib qho qauv rau cov thicknesses peb tab tom tham txog. Cov khoom sib tw tiag tiag yog brittleness. Ib qho kev cuam tshuam ntawm qhov tsis ncaj ncees lawm, zoo li lub ces kaum thaum tuav lossis lub cuab yeej poob, tuaj yeem ua rau tawg uas nthuav tawm. Koj tsis tuaj yeem welded zoo li hlau; nws yuav tsum muaj cov txheej txheem ua ntej cua sov thiab tom qab cua sov, thiab txawm tias tom qab ntawd, nws yog thaj chaw, tsis yog qhov lav. Tias yog vim li cas qhov kev xyaum nrhiav thiab kev tswj xyuas zoo tsis tuaj yeem sib tham.
Qhov no yog qhov uas tus neeg muag khoom lub pedigree tseem ceeb. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) nrog lawv peb lub xyoo caum nyob rau hauv casting tsis yog tsuas yog muag ib tug duab; lawv muag cov txheej txheem tswj. Pouring kub, txias npaum li cas, inoculant hom - cov no dictate lub kawg grain qauv, uas ncaj qha cuam tshuam qhov brittleness thiab damping kuv hais. Koj tsis tuaj yeem tshawb xyuas qhov ntawd rau hauv ib feem; nws yuav tsum tau muab pov tseg los ntawm qhov pib.
Txheej txheem yog huab tais: Los ntawm Pwm mus rau Tshuab
Lo lus 'casing' txhais tau tias nws yog ib lub thawv, tab sis nws tsis tshua muaj ib lub thawv. Nws muaj cov ntsiab lus mounting, cov chaw nres nkoj dej, cov rooj zaum hauv lub rooj, thiab feem ntau cov kab hauv. Yuav ua li cas koj tsim cov yam ntxwv no yog qhov tseem ceeb. Rau qhov nyuaj sab hauv geometries, plhaub pwm lossis peev casting - ob qho tib si tshwj xeeb tau sau tseg rau QSY's site- feem ntau yog qhov pib. Lawv tso cai rau kom meej meej thiab zoo dua saum npoo tiav tshaj li cov xuab zeb casting, uas txo cov nqi ntawm cov khoom siv tom ntej.
Tab sis 'txo' yog qhov tseem ceeb. Koj yuav luag ib txwm xav tau machining. Lub rooj zaum bearing hauv a cam khwb cia hlau casing tsis yog lub qhov xwb; nws xav tau ib tug meej txoj kab uas hla, nto tiav (Ra), thiab feem ntau ib tug tshwj xeeb concentricity txheeb ze rau lwm lub rooj. Qhov no yog qhov uas ua ke machining muaj peev xwm cais cov neeg muag khoom. Yog tias lub hauv paus tseem ua haujlwm rau CNC ua haujlwm, lawv tuaj yeem tsim cov casting nrog cov nyiaj ua haujlwm zoo thiab cov khoom siv hauv siab. Kuv tau npau suav phem nrog cov casings los ntawm ib tug foundry uas tsis tshuab, qhov twg 'as-cam khwb cia' nto yog li ntawd inconsistent hais tias peb lub tshuab khw siv sij hawm ntau qhia thiab shimming tshaj txiav.
Hais txog machining, hlau yog abrasive. Nws noj cov cuab yeej txiav. Siv cov qib zoo ntawm cov carbide, cov dej txias kom zoo, thiab kev nrawm / cov khoom noj kom zoo rau cov hlau chip-breaking cwj pwm yog nws tus kheej kos duab. Tus khub zoo yuav tsis yog xa cov khoom nyoos; lawv mam li xa ib feem uas cov machined nto yog npaj rau kev sib dhos. Qhov kev sib koom ua ke-casting thiab machining nyob rau hauv ib lub ru tsev-txuag ib tug loj npaum li cas ntawm logistical mob taub hau thiab zoo ntiv tes taw.
Thaum Nws Ua Haujlwm, thiab Thaum Tsis Ua
Daim ntawv thov zoo meej? Nyob ruaj ruaj, siab-load, siab vibration ib puag ncig. Loj gearbox vaj tse yog classic. Cov hlau dampens iav suab nrov thiab kev vibration, thiab nws cov rigidity tswj cov iav sib dhos hauv qab load. Peb siv lawv rau hydraulic manifold blocks nyob rau hauv daim ntawv thov xovxwm - lub thermal stability yog ib qho tseem ceeb raws li cov roj kub cycled, tiv thaiv distortion uas yuav xau siab.
Qhov kev ua tsis tiav? Txhua yam uas muaj qhov siab tensile lossis shock loads. Kuv nco qab txog qhov project rau cov khoom siv ua liaj ua teb mobile. Tus tsim hu ua a cam khwb cia hlau casing kom txuag tau tus nqi tshaj ib feem ntawm forged steel. Nws dhau qhov kev xeem thauj khoom zoo li qub tab sis ua tsis tau zoo hauv kev sim tom qab ob peb lub hlis. Kev cuam tshuam rov qab los ntawm kev hla cov av ntxhib tsim micro-cracks uas loj tuaj. Zaj lus qhia tsis yog hlau yog 'phem', tab sis hais tias peb tau misapplied nws. Tus nqi peb txuag ntawm cov khoom raug tshem tawm kaum npaug los ntawm qhov kev pab cuam retrofit.
Lwm qhov hloov maj mam yog corrosion hauv kev pabcuam tshwj xeeb. General nto xeb yog ib yam. Tab sis yog tias lub casing yog ib feem ntawm lub voj voog dej ntsev, txawm tias tsis tu ncua, qhov corrosion tuaj yeem dhau los ua galvanic thiab hauv zos, ua rau pitting thiab qhov tshwm sim. Nyob rau hauv cov xwm txheej zoo li no, kev qhia txog ntau dua-nickel alloy hlau los yog npaj rau cov txheej txheem tshwj xeeb los ntawm qhov pib yog qhov tseem ceeb. Nws tsis yog kev xav tom qab.
Alloy Nuance thiab Supplier Synergy
'Cast Iron' tsis yog ib qho khoom siv. Grey hlau, ductile hlau (nodular hlau), compacted graphite hlau - txhua tus muaj ib tug sib txawv matrix. Ductile hlau, nrog nws cov spheroidal graphite, muaj qee qhov muab rau nws, ua lag luam me ntsis ntawm damping rau kev cuam tshuam zoo dua. Xaiv cov qib zoo yog qhov kev txiav txim siab tsim qauv.
Qhov no yog vim li cas tus neeg muag khoom cov khoom siv ntau yog qhia. Thaum twg QSY npe cam khwb cia hlau, hlau, stainless, thiab tshwj xeeb alloys xws li npib tsib xee-raws li sawv daws yuav, nws qhia tau hais tias lawv to taub cov no yog engineering xaiv, tsis yog tsuas yog cov khoom muag khoom. Qee zaum, cov lus teb tsis yog hlau ntshiab. Rau lub casing xav tau kev kub siab tiv thaiv, kev txav mus rau nickel-based alloy yuav tsim nyog, txawm tias tus nqi dhia dhia. Ib tus neeg koom tes ua haujlwm zoo tuaj yeem qhia qhov kev sib tham raws li qhov tseeb ntawm kev ua haujlwm, tsis yog cov ntaub ntawv xwb.
Kev sib koom ua ke ntawm lawv lub plhaub / kev nqis peev casting thiab CNC machining yog qhov ua tau zoo. Rau qhov nyuaj valve casing, lawv muaj peev xwm nrum nyob rau hauv lub ntxhib ntws passages thiab chaw nres nkoj threads, ces CNC tshuab lub sealing nto thiab flange ntsej muag mus rau ib tug zoo meej tag. Qhov kev sib xyaw ua ke no feem ntau ua rau qhov zoo tshaj plaws ntawm kev ua tau zoo, lub sijhawm ua haujlwm, thiab tus nqi. Sim ua kom tshuab tag nrho cov yam ntxwv los ntawm cov khoom thaiv yuav txwv tsis pub kim thiab siv sijhawm.
Xaus Kev xav: Ib qho cuab yeej hauv Cov Khoom Siv
Yog li, txhawm rau sau qhov no, a cam khwb cia hlau casing yog ib qho cuab yeej tshwj xeeb. Nws tsis yog inherently outdated los yog superior. Nws tus nqi yog nyob rau hauv nws qhov tshwj xeeb ua ke ntawm damping, castability rau complex duab, thiab kuj tsis tshua muaj nqi khoom. Cov drawbacks - hnyav, brittleness, corrosion nyiam - yog tswj los ntawm ntse tsim, tsim nyog specification, thiab xaiv ib tug raug koom tes uas tswj tag nrho cov txheej txheem los ntawm yaj mus rau machined ib feem.
Qhov kev xaiv tiag tiag hauv ntiaj teb feem ntau npau taws rau qhov no: koj puas xav tau qhov kev vibration thiab thermal stability ntau dua li koj xav tau lub teeb yuag lossis corrosion tsis kam? Yog tias muaj, thiab yog tias qhov chaw thau khoom feem ntau yog compressive, hlau yog tej zaum koj cov lus teb. Tab sis ua hauj lwm nrog ib tug foundry uas nug koj txog kev khiav hauj lwm ib puag ncig, lub voj voog load, thiab cov ntsiab lus interface. Cov uas tsuas yog coj ib daim duab thiab nqe lus yog cov uas yuav ua rau koj muaj teeb meem.
Thaum kawg, nws yog hais txog haum. Thiab qee zaum, cov khoom qub, hnyav, tsis zoo yog qhov haum rau txoj haujlwm, ntsiag to ua nws txoj haujlwm ntev tom qab qhov kev xaiv 'siab dua' yuav tau hu nws tawm. Koj tsuas yog yuav tsum paub siv qhov twg.
