Yuav ua li cas thiaj paub cov lus qhia thiab cov qauv ntawm cov saw hlau

1. Ntsuas qhov suab ntawm cov saw hlau thiab qhov deb ntawm ob lub pins.

2. Qhov dav ntawm sab hauv, qhov no muaj feem cuam tshuam nrog qhov tuab ntawm lub sprocket.

3. Qhov tuab ntawm lub phaj saw hlau kom paub seb nws puas yog hom txhawb nqa.

4. Lub cheeb tsam sab nraud ntawm lub menyuam, qee cov saw hlau siv cov menyuam loj.

5. Feem ntau hais lus, tus qauv ntawm cov saw hlau tuaj yeem raug tshuaj xyuas raws li plaub cov ntaub ntawv saum toj no. Muaj ob hom saw hlau: A series thiab B series, nrog tib lub suab thiab cov kab sib txawv ntawm cov menyuam.

1. Ntawm cov khoom zoo sib xws, cov khoom saw hlau tau muab faib ua pawg raws li cov qauv yooj yim ntawm cov saw hlau, uas yog, raws li cov duab ntawm cov khoom, cov khoom thiab cov khoom sib xyaw nrog cov saw hlau, qhov sib piv ntawm cov khoom, thiab lwm yam. Muaj ntau hom saw hlau, tab sis lawv cov qauv yooj yim tsuas yog cov hauv qab no xwb, thiab lwm cov yog cov kev hloov pauv ntawm cov hom no.

2. Peb pom tau los ntawm cov qauv saw hlau saum toj no tias feem ntau cov saw hlau yog ua los ntawm cov phaj saw hlau, cov koob saw hlau, cov bushings thiab lwm yam khoom. Lwm hom saw hlau tsuas muaj kev hloov pauv sib txawv rau lub phaj saw hlau raws li qhov xav tau sib txawv. Qee qhov muaj cov scrapers ntawm lub phaj saw hlau, qee qhov muaj cov kabmob qhia ntawm lub phaj saw hlau, thiab qee qhov muaj cov menyuam ntawm lub phaj saw hlau, thiab lwm yam. Cov no yog kev hloov kho rau kev siv hauv ntau daim ntawv thov.

Txoj kev sim

Qhov tseeb ntawm qhov ntev ntawm saw yuav tsum tau ntsuas raws li cov hauv qab no:

1. Yuav tsum ntxuav cov saw hlau ua ntej ntsuas.

2. Qhwv cov saw hlau uas raug sim ncig ob lub sprockets, thiab sab saud thiab sab hauv qab ntawm cov saw hlau uas raug sim yuav tsum tau txhawb nqa.

3. Ua ntej ntsuas, cov saw yuav tsum nyob twj ywm li 1 feeb nrog ib feem peb ntawm qhov tsawg kawg nkaus tensile load siv.

4. Thaum ntsuas, siv qhov ntsuas qhov ntsuas tau teev tseg rau ntawm cov saw hlau kom nruj cov saw hlau sab saud thiab sab qis, thiab xyuas kom meej tias cov saw hlau thiab lub sprocket sib txuas ua ke.

5. Ntsuas qhov nruab nrab ntawm ob lub sprockets.

Kev ntsuas qhov ntev ntawm cov saw hlau:

1. Yuav kom tshem tawm qhov kev ua si ntawm tag nrho cov saw hlau, nws yog ib qho tsim nyog los ntsuas nrog qee qib ntawm kev rub tawm ntawm cov saw hlau.

2. Thaum ntsuas, txhawm rau kom txo qhov yuam kev, ntsuas ntawm 6-10 knots.

3. Ntsuas qhov ntev sab hauv L1 thiab sab nraud L2 ntawm cov menyuam ntawm tus lej ntawm cov ntu kom pom qhov loj me txiav txim siab L = (L1 + L2) / 2.

4. Nrhiav qhov ntev ntawm txoj saw hlau. Tus nqi no yog muab piv rau tus nqi txwv tsis pub siv ntawm txoj saw hlau hauv cov khoom dhau los.

Cov qauv saw: Nws muaj cov txuas sab hauv thiab sab nraud. Nws muaj tsib qhov me me: phaj txuas sab hauv, phaj txuas sab nraud, tus pin, lub tes tsho, thiab lub menyuam. Qhov zoo ntawm cov saw nyob ntawm tus pin thiab lub tes tsho.
