Oxyacetylene vuam, feem ntau hu ua roj vuam, yog txheej txheem uas tso siab rau kev sib xyaw ntawm cov pa thiab acetyleneThaum sib xyaw ua ke hauv qhov sib npaug ntawm tes tuav los yog lub tshuab raj Cov nplaim hluav taws kub kub yog tsim nrog qhov kub ntawm li 3,200 deg. C.
Koj tuaj yeem txuas nrog oxy-acetylene dab tsi?
Cov hlau twg tuaj yeem txuas nrog Oxy-Acetylene? Yog tias Oxy-Acetylene welding tau ua tiav txoj hauv kev, nws tuaj yeem siv los txuas tag nrho cov khoom lag luam hlau. Cov hlau uas welded nrog Oxy-Acetylene muaj xws li qis-alloy steel, qis-carbon steel, wrought hlau, thiab cam khwb cia hlau.
Qhov twg yog cov roj hauv oxy-acetylene gas welding?
33 002 oxy-acetylene vuam: Gas vuam nyob rau hauv uas cov roj roj yog acetylene. Nco tseg. Lwm cov roj roj kuj tseem siv tau nrog cov pa oxygen (piv txwv li butane, hydrogen, thiab propane): Hauv cov xwm txheej zoo li no, kev hloov pauv rau lub sijhawm thiab cov ntsiab lus yog qhov tsim nyog.
Koj siv oxy-acetylene roj vuam li cas?
- Cais ntxuav ob qho tib si oxygen thiab roj kab.
- Qhib roj roj valve 1/2 tig.
- Khuv nplaim nrog tus ntaus.
- Ntawm roj roj ntws kom txog thaum nplaim taws tawm ntawm qhov kawg thiab tsis muaj pa taws.
- Txog kom txog thaum nplaim taws rov qab mus rau qhov kawg.
- Qhib oxygen valve thiab kho kom tsis muaj nplaim taws.
- Txo qis oxygen qib thiab ua kom tsim nyog hloov kho.
Vim li cas oxy-acetylene gases nyiam rau vuam?
Acetylene ua kom muaj nplaim taws kub ntawm ~ 3100 degree Celsius nrog rau cov pa oxygen Qhov kub kub no ua rau acetylene yog qhov tsim nyog rau cov roj vuam hlau. 2. Vuam: Thaum kub hnyiab hauv cov pa, acetylene tsim ib cheeb tsam txo, uas yooj yim ntxuav cov hlau nto.
