Yuav Ua Li Cas Saib Cov Machinery Castings Los Tsis Zoo

Ningbo Qianhao Hlau Khoom Co., Ltd | Updated: Sep 29, 2017

Yuav ua li cas xyuas cov Machinery Casting defects

Los xyuas kom zoo ntawm Machinery Castingss, Machinery Castingss yuav tsum yog raws li kev sib txawv thiab kev siv, siv ntau txoj kev soj ntsuam, lub sij hawm txhim kho ntawm cov tsis raws cai uas tsis raug tso cai. Kev txheeb xyuas kev soj ntsuam feem ntau ua raws li cov hauv qab no.

(A) qhov kev kuaj pom ntawm qhov chaw ntawm qhov kev soj ntsuam yuav tsum muaj nyob rau hauv qhov tsim nyog lub teeb pom kev zoo rau kev pom - txhais tes kov thaiv, nrog lub siab ntawm qhov mob ntawm qhov kev txheeb xyuas, nrog ntsuas kev ntsuas kom tau Machine Machinery Casting size cov ntaub ntawv, kev tshawb pom los txiav txim xyuas qhov tseeb ntawm Machinery Castings Defect rate.

(B) tshuaj ntsuam ntawm tag nrho Machinery Castingss, tshuaj muaj pes tsawg leeg tseem ceeb heev, yog li feem ntau, cov tshuaj lom neeg muaj pes tsawg leeg yog qhov kev pom zoo. Tshuaj lom neeg muaj pes tsawg tus kuj txiav txim siab cov khoom siv dag zog ntawm Machinery Castings thiab qhov tshwm sim ntawm tsis xws luag.

(3) mechanical performance test Hardness test yog thawj qhov kev ntsuam xyuas seb puas muaj qhov muaj tshwm sim hauv Machinery Castings txhais tau tias, pib ntawm lub xyoo pua no, Tebchaws Meskas yog nyob hauv xuab zeb ntawm txoj kev xeem ntawm Machinery Castings Machinery Castings lub tog raj kheej lub taub hau, xws li raws li hardness tshaj ib qho nqi uas yog kev tsis pom kev los ua kom khawb. Qhov no yog qhov yooj yim thiab txawv txawv.

(4) metallographic muas (metallographic microscope test) nrog lub tsom iav qhov muag thiab tom qab ntawd ua kom muaj 50-2000 zaug mus saib cov nplaim hlau, cov qauv ntawm qhov tsis muaj kev yaig nyob rau hauv cov xwm txheej ntawm cov vaj tse (siv qaim, tsaus nti thiab polarized, cuam thiab micro hardness thiab lwm yam kev siv nrog reference GB10561-89 kev ntsuam xyuas), tom qab erosion ntawm lub koom haum thiab grain loj soj ntsuam. Txoj kev no yog siv los tshawb xyuas cov kab mob me me, tiam sis feem ntau kuj tseem siv los kawm txog tus cwj pwm me me ntawm cov tsis xws luag hauj lwm.

(5) Ntsuas cov kev ntsuas (tsis kuaj kev puas tsuaj) Ntawm lawv, cov tshuaj osmotic kuaj (ISO3452), kev nqus hlau txoj kev nqus hlau, txoj kev ntsuas tam sim no, tsuas yog siv rau Machinery Castings qhov chaw lossis ntu ib feem ntawm qhov kev kuaj xyuas tsis raws, kev soj ntsuam ntawm cov teeb meem sib sib zog nqus nyob rau hauv Machinery Castings, Kab kev kis kab mob (ISO5579), tomography thiab ultrasonic flaw nrhiav kom raug. Nondestructive xeem tau tsim tawm sai heev nyob rau hauv xyoo tas los, ua tsaug rau cov ntaub ntawv ua thiab kho vajtse nyhav kom txav tau, txhim kho txoj kev cia siab thiab muaj kev soj ntsuam.
