Kev kho tshuab rau ntxaib-ntsia hlau chim

Thaum kev txhaj ntsia hlau sib ntsib nyuaj rau nias cov khoom ntawm kev pub khoom noj khoom haus ntawm lub chaw nres nkoj pub dawb raws qhov ntev ntawm cov thoob txwv los thauj cov khoom siv, cov ntsia hlau yuav plam. Thaum lub hau ntswj ua ntej molding rau theem, cov ntsia hlau tig hauv lub thoob rau cov khoom siv ntawm cov khoom siv txhaj tshuaj tom ntej, ua rau cov ntsia hlau mus plam.

Lub puab sab hauv hardness ntawm lub thoob yog siab tshaj qhov ntawm cov ntsia hlau, thiab nws kev puas tsuaj tshwm sim tom qab ntawm cov ntsia hlau. Qhov scrapping ntawm lub thoob tsib yog hais txog qhov nce nyob rau hauv inner diam vim hnav thiab kua muag. Txoj kev kho rau ntxaib-ntsia hlau chim tsuas yog suav nrog cov ntsiab lus hauv qab no.

1. Thaum txoj kab uas hla ntawm lub thoob dej nce ntxiv vim tias hnav, yog tias tseem muaj qee qhov ntawm lub taub loj tuaj yeem npaj tau raws li cov kab no.

2. Lub inner iner ntawm lub thoob yog machined, thiab rov ua dua nrog tungsten carbide alloy, thiab tom qab ntawd precision machined rau lub taub loj.

3. Feem ntau, cov seemogenization seem ntawm lub tshuab chim ntoo hnav tawm sai. Seem no (5 ~ 7D ntev) tuaj yeem haum nrog lub pob khawm lub tes tsho thiab cov nitrogen impregnated alloy Liner. Lub qhov taub sab hauv uas cov taub yuav tsum hais txog cov ntsia hlau txoj kab no thiab tau sab laug hauv qhov sib dhos uas haum rau kev ua thiab npaj.

Ntsia thawv thiab chim yog ob qhov tseem ceeb, ib qho yog ib tus pas nrig khi, thiab lwm qhov yog lub taub me me thiab ntev. Lawv cov txheej txheem kev kho tshuab thiab cov txheej txheem kho cua sov yog cov txheej txheem kub, thiab ua kom tau qhov tseeb yog qhov nyuaj. Yog li, seb puas kho tau los yog hloov ob qhov chaw tom qab hnav thiab kua muag yuav tsum tau kev txheeb xyuas kev lag luam los ntawm kev lag luam kev lag luam. Yog tias tus nqi kho yog qis dua tus nqi ntawm kev hloov cov ntsia hlau, tom qab ntawv txiav txim siab kho tsis yog qhov tseeb xaiv. Qhov sib piv ntawm cov nqi kho thiab hloov kho tus nqi tsuas yog ib qho. Tsis tas li ntawd, nws tseem nyob ntawm qhov kev sib piv ntawm cov nqi kho rau lub sijhawm siv cov ntsia hlau tom qab kho tau rau tus nqi kho thiab siv cov ntsia hlau. Txais cov phiaj xwm nrog cov piv txwv me me yog kev lag luam thiab kev xaiv yog.
