Cov khoom siv ntawm cov rooj tog uas yog cov rooj tog uas muaj rau cov neeg siv kev paub thiab lub neej?

Cov ntaub ntawv ntawm lub citer ncaj qha txiav txim siab nws cov neeg siv kev paub (du, thiab lub neej, thiab thauj khoom tsis kam, thiab thauj khoom {{1} {{1} - bearing muaj peev xwm). Cov ntaub ntawv tseem ceeb tau txheeb xyuas hauv qab no:

 

1. Log Khoom (hu rau hauv av)

Roj Hmab Log: Zoo dua nyob ntsiag to (tsawg dua los yog sib npaug rau 40 decibels), tiv thaiv cov av hauv av, thiab muab cov ntaub qhwv zoo heev. Txawm li cas los xij, lawv muab nruab nrab hnav tsis kam thiab muaj kev ntxim nyiam roj, tshav ntuj, thiab qis kub (lab) yog txo los ntawm 30-50%), nrog ib lub neej ntawm 1-2 xyoos.

 

Polyurethane (PU)-coated wheels: The best overall choice. They offer a balanced balance of quietness and wear resistance (adjustable hardness from A70-95), a wide load capacity (50-300 kg), and are water and low-temperature resistant. Their lifespan is 2-3 years on smooth surfaces and 1-2 years on rough surfaces. Low-quality PU wheels are prone to debonding and are sensitive to high temperatures (>80 degree).

 

Nylon wheels: They offer a load capacity (>300 kg), muaj sia nyob tiv thaiv (lifespan ntawm cov nplaim taws yog 20-30% ntev dua li pu log), thiab yog cov roj thiab corrosion resistant. Txawm li cas los xij, lawv tsis muaj suab nrov (ntau dua lossis sib npaug nrog 50 decibels, thiab yooj yim cov plag tsev yooj yim, ua rau lawv muaj kev txom nyem hauv tsev.

 

Metal wheels: They offer strong load-bearing capacity (>500kg) and are durable (over 5 years). However, they are noisy (>60 Decibels), tuaj yeem ua rau cov plag tsev, yog hnyav thiab nyuaj rau kev thawb, xav tau kev tiv thaiv kev tu thiab xeb, thiab tsis tshua muaj siv hauv tsev.

 

2. Cov Khoom Siv Nrig (Txhawb Nqa thiab Kev Tiv Thaiv Xub)

Galvanized steel: muaj lub zog nruab nrab thiab lub neej ntawm 3-5 xyoos nyob rau hauv cov chaw qhuav. Rusts yooj yim hauv cov chaw noo noo (cov nyiaj ntawm 1-2 xyoos).

 

Stainless hlau nkhaus: Qhov kev xaiv uas nyiam rau xeb tiv thaiv. Lawv muaj zog, tiv taus ya raws thiab roj, thiab muaj lub neej ntawm ntau tshaj 5 xyoos.

 

Cov kab hlau txawv teb chaws: Lawv nquag muaj xeb thiab qaug dab peg, thiab muaj lub neej luv luv (1 xyoo nyob rau hauv cov chaw qhuav, 3-6 lub hlis nyob rau hauv ib puag ncig qhuav). Lawv tsis pom zoo.

 

3. Cov kabmob cov khoom siv (du thiab ntsiag to)

Pob bearings (steel lossis nylon): du thiab ntsiag to (Nylon yog quieter). Cov pob zeb pob muaj lub neej ntawm 3-5 xyoos (xav tau lubrication); Nylon pob muaj lub neej muaj ib lub neej ntawm 2-3 xyoos rau loads tsawg dua lossis sib npaug rau 100kg.

 

Bushings (tsis muaj bearings): siab tiv taus, nquag mus rau cov suab nrov, hnav zoo dua, thiab lub neej ntawm tsuas yog 6-12 lub hlis.

 

Ntsiab lus thiab cov lus pom zoo:

Qhov kev ua tiav zoo rau kev siv hauv tsev: Pu -} coated log + stainless hlau nkhaus + pob bearings. Lawv muab cov kev tiv thaiv, cov xeb tsis kam, kev tiv thaiv pem teb, thiab lub plab zom mov, nrog lub neej ntawm 3-5 xyoos.

 

Tej xwm txheej tshwj xeeb:

Ntoo / cov pobzeb pem teb uas yuav tsum muaj suab nrov nrov → cov roj hmab muag muag roj hmab.

Cov chaw sawv ntxov (chav ua noj / chav dej) → steel hlau nkhaus + pu log.

Cov rooj tog hnyav → High high - thauj}}} tus tiv thaiv pick (nrog tiv thaiv pem teb).

 

Cov khoom siv tseem ceeb: zam cov log roj hmab, qis}} haze} hardness yas lub log, thiab cov qauv hlau tsis muaj kev tiv thaiv tsis muaj kabmob.
