Hlau hlau foob yog ib qho khoom siv dav thiab siv ntau tshaj plaws ntawm kev ua lag luam. Txawm li cas los xij, thaum muaj ntau tus neeg siv tau ntsib nrog cov hlau xaim rau thawj zaug, lawv tseem tsis paub yuav siv nws li cas? Ntawm no yog cov ncauj lus kom ntxaws txog kev siv cov txheej txheem steel hlau ntsaws ruaj ruaj:
1. Txiav ib daim ntawm cov hlua khi rau qhov ntev uas koj xav tau, xws li 10cm, 15cm, thiab lwm yam. Cov hlua khi uas tuaj yeem siv nrog cov yas ntsaws ruaj ruaj muaj xws li roj hmab-coated steel hlau, hlau threaded sealing hlau, muaj yeeb yuj roj hmab-coated hlau thiab tooj liab, thiab lwm yam;
2. Tshem tawm cov hlau lead, uas feem ntau muaj 3 qhov: 2 ntawm ib sab thiab 1 sab. Txiav qhov ntev ntawm cov hlau foob kab los ntawm lub qhov hauv qab ntawm sab nrog 2 qhov, uas yog lub taub hau hlau foob. Hla nws los ntawm ib lub qhov nyob hauv qab (nco ntsoov tias nws kuj dhau los ntawm lub qhov ntawm lub tshuab rotary), thiab tom qab ntawd tig nws ib lossis ob zaug;
3. Lub sijhawm no, cov hauv qab tau raug kho, thiab tom qab ntawd hla lwm qhov kawg ntawm cov kab hlau lead sealing los ntawm ob lub qhov sab nraud ntawm cov khoom koj xav muab khi (xws li lub ntsuas hluav taws xob), thiab tom qab ntawd dhau los ntawm ob qhov sib txawv ntawm qhov khoom. cov hlau nplaum, thiab tom qab ntawd tig cov hniav nyob rau sab saum toj ntawm lub foob clockwise;
4. Tig kom txog thaum koj xav tias nws tuaj yeem kaw tau, nres rotating, thiab tom qab ntawd tawg cov hniav nyob rau saum cov hlau foob.
