Manifold yog dab tsi?

Lub hli tas los ib tug txiv leej tub hu kuv txog ib lub pwm uas nws yuav los ntawm Tuam Tshoj. Kaum rau kab noj hniav hau pwm. Zoo nkauj ua haujlwm sab nraud. Nws tua nws thiab rau qhov kab noj hniav yuav tsis puv. Tshawb xyuas lub nozzles, kuaj lub rooj vag, txhua yam zoo li zoo. Rub lub manifold tawm thiab pom qhov teeb meem. Cov channel mus rau cov tee no tau drilled ntawm 5mm. Lwm kaum yog ntawm 8mm. Leej twg tshuab lub manifold tsuas yog rub lub laum tsis ncaj ncees lawm ib nrab thiab tsis muaj leej twg ntes tau.

Qhov ntawd yog dab tsi manifold ua. Nws yog qhov faib thaiv. Yas los hauv ib lub qhov, tawm mus ntau lub qhov. Ntsia nws thiab tsis muaj dab tsi ua haujlwm zoo.

What Is Manifold?

Ntu Tsis Muaj Neeg Hais Txog

Cov txiv neej siv mus ib txhis xaiv cov lus qhia nozzle thiab rooj vag style. Lawv yuav sib cav txog lub rooj vag valve piv rau cov rooj vag thermal kom txog thaum koj xav tawm hauv chav. Tab sis lub manifold zaum hauv nruab nrab ntawm txhua qhov ntawd?

"Cia li ua kom nws ua haujlwm."

Kuv tau hnov txog qhov project engineers ntau zaus tshaj qhov kuv suav tau.

Lub manifold yog ib qho thaiv ntawm cov cuab yeej hlau nrog qhov drilled los ntawm nws. Qhov ntawd yog nws. H13 feem ntau. Lub qhov txuas koj sprue bushing rau koj lub nozzle tee. Cov cua sov ua kom cov hlau kub kom cov yas nyob twj ywm melted thaum nws mus los. Yooj yim.

Tsuas yog thaum nws tsis yog.

Cov channel sab hauv yuav tsum yog qhov loj me rau koj qhov hnyav txhaj tshuaj. me me heev thiab koj nyob nraum sib ntaus sib tua siab poob tag nrho txoj kev. Loj dhau thiab cov khoom zaum hauv qhov ntev dhau, ua noj, tig mus rau cov khib nyiab. Kuv tau khiav txoj haujlwm kho mob xyoo rov qab uas peb tau txais cov specks dub hauv cov khoom PC meej. Tsav txhua tus neeg vwm rau ob lub lis piam. Tshaj tawm yav dhau los txhaj tshuaj molding manifold tus neeg muag khoom tau nthuav dav cov channel rau "dhau zoo dua." Cov khoom tau degrading nyob rau hauv lub sij hawm ntxiv nyob.

Hloov mus rau qhov loj me me los ntawm Incoe thiab qhov teeb meem ploj mus ib hmos.

Cov neeg kub kub muaj kev xav

Tham nrog Mould-Masters txiv leej tub thiab nws yuav qhia rau koj tias cov khoom siv hluav taws xob sab nraud yog tib txoj kev mus. Cartridge rhaub rau sab nraud, cua sov ua hauv.

Tham nrog ib tug laus Husky thiab nws yuav cog lus los ntawm cov cua sov sab hauv. Cua sov txoj cai nyob rau hauv lub melt kwj. Teb sai dua. Kev tswj zoo dua.

nkawd ob leeg yog lawm. Nkawd ob leeg yuam kev. Nyob ntawm qhov koj tab tom khiav.

Kuv nyiam cov cua sov sab nraud rau kev ua haujlwm feem ntau. Tsawg mus tsis ncaj ncees lawm hauv txoj kev ntws. Tab sis kuv tau pom cov tshuab cua sov sab hauv khiav tau ntau xyoo tsis muaj teeb meem ntawm cov ntawv thov raug. Ntim phab ntsa nyias, lub voj voog nrawm, cov ntaub ntawv uas tsis mloog me ntsis ntxiv shear. Txhua qhov kev txhaj tshuaj molding kub khiav lag luam yog ob qho tib si. Xaiv raws li koj cov txheej txheem, tsis yog ntawm qee tus neeg muag khoom yog thawb lub quarter ntawd.

Ntawm no yog qhov uas tau txais cov neeg. Hlau nthuav thaum koj kub nws. Ib tug manifold uas yog 600mm dav ntawm chav tsev kub tej zaum yuav 601.5mm ntawm khiav kub. Tsis zoo li ntau txog thaum koj paub tias tag nrho koj cov ntsaws ruaj ruaj nyob ntawm qhov kev nthuav dav.

Lub manifold bolts down ntawm nws qhov chaw. Thaum nws sov, nws loj hlob sab nraud ntawm qhov chaw nruab nrab. Cov nozzles zaum hauv hnab ris hauv cov phaj pwm. Ntawm chav tsev kub muaj qhov sib txawv ntawm lub ntsej muag manifold thiab lub xub pwg nozzle. Kub txhua yam thiab qhov sib txawv ntawd kaw. Lub manifold thawb tawm tsam cov nozzles. Hlau rau hlau foob. Tsis muaj cov yas xau tawm.

Tau qhov sib txawv tsis ncaj ncees lawm txias thiab koj muaj teeb meem. Kuv tau ua hauj lwm nrog ib tug txhaj tshuaj molding tooling neeg muag khoom nyob rau hauv Ohio uas tsim cov pwm zoo nkauj tab sis cia screwing li manifold preload xam. Pwm yuav tuaj rau hauv, koj yuav sov lawv, thiab cov yas yuav oozing tawm txhua qhov chaw vim hais tias lub manifold tsis ua kev sib cuag nrog lub nozzles. Los yog qhov teeb meem rov qab- txias txias heev, tej yam kub kub, thiab koj tsoo lub rooj zaum nozzle.

Synventive tshaj tawm preload specs rau tag nrho lawv cov tshuab. Mould-Masters zoo li ntawd. Nyeem phau ntawv. Ua lej. Xyuas nws ob zaug.

Qib Steel

H13 ua haujlwm feem ntau. Nws yog yam uas txhua tus siv. Tuav mus rau thermal cycling, tshuab zoo, tsim nyog tus nqi.

Tab sis yog tias koj khiav PVC lossis ib yam dab tsi nrog cov nplaim hluav taws, H13 yuav corrode. Kuv tau pom manifolds tawm zoo li swiss cheese tom qab kaum yim lub hlis ntawm FR-ABS txoj haujlwm. Mus nrog 420 stainless lossis S136 rau txhua yam corrosive. Tus nqi them ua ntej. Txuag nyiaj mus ntev.

Ib yam uas kuv tau kawm txoj kev nyuaj- yog tias koj tau txais ib qho khoom siv los ntawm kev txhaj tshuaj molding cov chaw tsim khoom txawv teb chaws, xyuas cov qib steel. Tau txais daim ntawv pov thawj. Kuv tau pom "H13" manifolds uas tau meej meej tsis H13 raws li sai npaum li cas lawv hnav tawm.

Channels thiab Flow

Cov channel sab hauv tau txais phom- laum ces honed. Yuav tsum du li iav nyob rau hauv. Txhua qhov chaw ntxhib dhau los ua qhov chaw uas cov khoom dai. Cov xim hloov mus ib txhis. Cov khoom qub degraded flakes tawm thiab paug qhov chaw.

Channel txoj kab uas hla tseem ceeb tshaj li cov neeg feem coob paub. Cov txiv neej ua lub kaus mom thiab kaw khiav me me, tej zaum 6-8mm. Automotive khoom nrog kev txhaj tshuaj loj xav tau cov channel loj dua, 12mm, 14mm, qee zaum ntau dua. Koj qhov kev pabcuam kev txhaj tshuaj molding pwm tuaj yeem qhia koj cov dab neeg txaus ntshai txog manifolds uas tau hais tsis raug rau daim ntawv thov thiab tsis tau khiav txoj cai.

Flow balance yog lwm daim. Nyob rau hauv ib txwm sib npaug manifold tag nrho cov channel yog tib qhov ntev ntawm inlet mus rau txhua qhov poob. Yas nkag mus rau txhua qhov kab noj hniav tib lub sijhawm, tib qhov kub thiab txias, tib lub siab. Unbalanced manifolds muaj qee cov channel ntev dua li lwm tus. Koj tuaj yeem ua rau lawv ua haujlwm nrog kev hloov kho qhov kub thiab txias tab sis nws ib txwm muaj kev cuam tshuam.

Channels And Flow

Thaum khoom tawg

Cua sov tuag. Thermocouples drift. Nws tshwm sim.

Cartridge rhaub nyob rau hauv ob- lub khw ua haujlwm yuav kav tau ob xyoos, tej zaum peb. Internal heaters tsawg dua. Khaws cov khoom seem. Thaum ib cheeb tsam poob qis koj tsis xav tos peb lub lis piam rau ntu.
Thermocouple nyeem ntawv drift lub sijhawm. Tus maub los hais tias 450℃F tab sis cov hlau tiag tiag yuav yog 430℃F lossis 470℃F. Ib xyoos rub cov TCs thiab xyuas lawv tawm tsam cov ntaub ntawv paub. Kev pov hwm pheej yig.

Qhov tsis zoo tiag tiag yog cov teeb meem ntws channel. Hnav, corrosion, tawg. Yog tias koj tab tom khiav cov ntaub ntawv abrasive- iav ntim, cov ntxhia pob zeb puv - tshuaj xyuas cov channel thaum lub sijhawm tu loj. Ib qho borescope ua haujlwm. Yog li rub lub manifold thiab xa tawm mus kuaj. Catching hnav thaum ntxov txhais tau tias koj tuaj yeem tau txais cov channel resleeved lossis repolished. Tos ntev heev thiab koj tab tom yuav ib lub manifold tshiab.

Yuav Cov Lus Qhia

Standard manifolds tuav cov haujlwm txheem. Plaub poob, yim poob, ntau configurations. Koj tus neeg muab khoom rub tawm ntawm lub txee, xa tawm, ua tiav.

Kev cai ua haujlwm yuav siv sijhawm. Weird kab noj hniav sib nrug, angled tee, valve gate systems, pawg pwm. Daim duab rau rau mus rau kaum lub lis piam ua lub sij hawm rau kev cai manifold ua hauj lwm. Tsis txhob hnov qab tias koj xav tau ib lub hlis ua ntej koj cov pwm yuav tsum xa tuaj.

Thiab muab cov ntaub ntawv. Channel qhov ntau thiab tsawg, ntsuas cua sov specs, qhov chaw thermocouple, preload xav tau, daim ntawv pov thawj steel. Koj yuav xav tau tag nrho nws thaum kawg. Cov khw uas muaj teeb meem - pub dawb rau xyoo yog cov uas khaws cov ntaub ntawv zoo.
