1. Lub Hom Phiaj
Lub hom phiaj ntawm cov neeg nqa khoom hnyav hnyav yog pab txhawb kev thauj mus los. Piv txwv li, lawv tau siv rau sab hauv tsev, ntau yam khoom siv thiab ntau lub tshuab tuav uas yuav tsum tau thauj hauv cov tsev. Lawv tau txhawb nqa los ntawm tib neeg txhais tes. Thov ua raws li cov hauv paus ntsiab lus hauv qab no: Txoj hauv kev thiab cov xwm txheej ntawm kev siv, siv kom raug thiab teeb tsa kom raug.
Qhov thib ob, kev siv thiab siv cov casters
Thaum siv cov neeg hnyav hnyav ua haujlwm hnyav, koj xav ua ntej txiav txim siab nws qhov kev siv, yuav tsum tau ua haujlwm, thiab cov xwm txheej siv (ntau yam siv), thiab tom qab ntawd xaiv hom uas tsim nyog. Thov xyuam xim rau cov hauv qab no:
1. Cov xwm txheej ntawm kev siv
Raws li cov cuab yeej tshwj xeeb rau kev txhim kho cov casters, txiav txim siab txoj kab uas hla ntawm cov caster, nws cov khoom siv, txheej txheem teeb tsa (xws li phaj-ntsia, thiab ntsia hlau-tsau, thiab lwm yam) thiab hom caster siv (xws li kev hloov pauv tau yooj yim, tsau, nres Hom, thiab lwm yam). Hauv ntej, qhov tsim nyog tshaj plaws yuav tsum raug xaiv tom qab hnyav raws li cov caster uas twb muaj lawm lossis ntau hom uas tuaj yeem xaiv tau.
2. Hais txog cov nres ntawm casters
Vim yog kev siv mus sij hawm ntev, cov neeg caij tsheb yuav ploj mus, thiab kev ua haujlwm ntawm cov casters yuav poob qis, yog li thov ua tib zoo saib nws txhua lub sijhawm.
Raws li qhov xwm txheej ib txwm muaj, cov yas caster (nylon, cob, thiab lwm yam) tom qab siv sijhawm ntev, nws qhov kev tiv thaiv kev sib hloov yuav raug txo kom tsawg.
Hais txog kev tiv thaiv kev sib hloov, thov siv lwm txoj hauv kev tiv thaiv kev sib hloov (xws li caster brakes, av tiv thaiv plam, thiab lwm yam) raws li cov khoom' kev nyab xeeb xav tau lossis tshwj xeeb xav tau tshwj xeeb.
3. Ib puag ncig ib puag ncig rau kev siv casters
Cov khoom lag luam dav dav tau siv hauv ib puag ncig hauv tsev teeb tsa ntawm chav sov, yog li sim zam kev siv lawv hauv ib puag ncig tshwj xeeb, xws li: kub, kub tsawg, kub ntau, kub ntau, acidity siab, alkalinity, siab ntsev cov ntsiab lus, Tshuaj lom kuab tshuaj , cov chaw nrog roj, lossis dej hiav txwv thiab cov kua tshuaj ncaj qha hu rau cov casters, uas yuav txo qis kev ua haujlwm ntawm cov casters.
Thaum nws tsis raug tso cai siv, nws yuav tsum tau nruab nrog lwm qhov kev ntsuas uas ntseeg tau hauv cov xwm txheej sib txawv, xws li cov khoom siv ntawm cov cuab yeej siv hlau, cov khoom ntawm cov casters, cov khoom siv roj nplua nyeem, thiab lwm yam kom hnyav nws, thiab coj mus rau hauv tus account tias qee cov ntaub ntawv yuav ua rau av.
4. Tsim nyog rau kev ua haujlwm load-bearing
Lub peev xwm nqa tau cov kabmob hauv cov lus piav qhia khoom hais txog kev thauj khoom dav dav uas yooj yim txav thaum thauj mus rau hauv av tiaj tus los ntawm kev ua haujlwm. Tib lub sijhawm, nws yog lub nra hnyav uas tuaj yeem nqa tawm hauv lub xeev muaj kev nyab xeeb ntev. Nws yog qhov tsim nyog los kwv yees tag nrho cov khoom thauj ua ntej. Nyhav, thiab tom qab ntawd xaiv tus caster tsim nyog raws li qhov tso cai thauj khoom. Feem ntau, tsuas yog 3 ntawm 4 tus casters nyob rau hauv kev quab yuam, yog li tag nrho qhov hnyav txwv yuav tsum yog theoretical *0.8 (uas yog, tsis txhob suav ntau dhau).
Thaum siv 4 tus neeg tsav tsheb, tag nrho qhov hnyav txwv=qhov tso cai thauj khoom ntawm txhua (1) caster*4*0.8. Thaum siv cov casters ntawm ntau qhov sib txawv, thov xa mus rau tus caster uas muaj qhov qis tshaj qhov ua haujlwm hnyav. Xam tag nrho qhov hnyav tshaj qhov hnyav-nqa qhov hnyav.
5. Txog kev nrawm
Qhov yuav tsum tau ua kom nrawm ntawm cov neeg hnyav hnyav yog: hauv qhov kub ib puag ncig ib puag ncig, tsis siab dua kev taug kev nrawm, hauv av tiaj tus, muaj qhov xwm txheej siv dav hauv lub xeev ua haujlwm tsis ua haujlwm. (Thov zam kev tsis tu ncua (tsis nres) siv cov plaub hau caster)
Caster log inch 75mm lossis tsawg dua ------ 2km/h lossis tsawg dua; 100mm lossis tsawg dua ------ 4km/h lossis tsawg dua.
