Qhov sib txawv tseem ceeb ntawm cov kua dej hydraulic thiab cov roj hydraulic yog cov kua dej hydraulic yog siv rau hauv kev sib kis tsis siv neeg hauv lub tsheb thaum cov roj hydraulic tsis tuaj yeem siv rau lub hom phiaj no.
Hydraulic roj yog feem ntau hom hydraulic kua. Yog li ntawd, ntau tus neeg nyiam siv ob lo lus sib pauv.
Hydraulic Fluid yog dab tsi?
Hydraulic kua yog qhov nruab nrab uas muaj txiaj ntsig zoo hauv kev hloov hluav taws xob hauv cov tshuab hydraulic xws li excavators, backhoes, hydraulic brakes thiab tsheb khib nyiab. Txawm hais tias qhov tseem ceeb ntawm kev siv cov kua dej hydraulic yog hloov lub zog, muaj qee qhov kev siv thib ob thiab. Piv txwv li: hloov hluav taws xob, tshem tawm cov paug, sealing, lubrication, thiab lwm yam. Cov yam ntxwv tseem ceeb ntawm cov kua dej hydraulic yog raws li hauv qab no:
- Thermal stability
- Hydrolytic stability
- Tsawg tshuaj corrosiveness
- Tsawg nyiam cavitate
- Long life
- Tus nqi qis, thiab lwm yam
Daim duab 01: Hydraulic Nres Nres Fluid
Thaum xaiv cov kua dej hydraulic, peb yuav tsum xav txog qhov viscosity ntawm cov kua. Cov kua yuav tsum muaj qhov tsawg kawg nkaus viscosity ntawm qhov ua haujlwm siab tshaj plaws. Tsis tas li ntawd, foaming ntawm hydraulic kua yog ib qho teeb meem uas tshwm sim thaum siv cov kua hydraulic. Ua npuas ncauj tuaj yeem degrade thiab cuam tshuam rau kev ua haujlwm ntawm lub cev. Yog li ntawd, peb yuav tsum tshem cov npuas uas ua rau hauv cov kua.
Hydraulic Roj yog dab tsi?
Hydraulic roj yog cov kua hluav taws xob uas muaj txiaj ntsig zoo hauv kev hloov hluav taws xob hauv hydraulic system. Txawm li cas los xij, vim nws yog flammable, nws tsis yog ib qho kev xaiv zoo los siv cov kua dej no hauv qhov chaw tsis muaj zog. Tias yog vim li cas, nyob rau hauv high-pressure tej yam kev mob, cov roj tsuag tuaj yeem ignite. Vim li no, tib neeg ua cov kua dej hydraulic los siv rau hauv qhov chaw ntawm cov roj hydraulic ua cov tshuaj tua hluav taws.
Hydraulic roj muaj cov roj thiab cov khoom ntxiv. Cov roj no ua ib qho nruab nrab rau kev hloov hluav taws xob nrog rau cov roj nplua nyeem thiab cov dej txias. Cov roj no tuaj yeem txo qhov corrosion hauv hydraulic systems, thiab nws tuaj yeem ua tau raws li qhov kub thiab txias. Muaj peb hom qauv ntawm cov roj hydraulic;
- General hydraulic roj - cov roj no muaj txiaj ntsig hauv cov tshuab hydraulic feem ntau vim nws cov khoom tiv thaiv kev sib txhuam thiab oxidation stability.
- Hnav-tiv taus hydraulic roj - cov roj no muaj txiaj ntsig zoo hauv cov tshuab tshwj xeeb uas ua haujlwm nyob rau hauv cov xwm txheej kub thiab kub.
- Nplaim hluav taws xob hydraulic roj - cov roj no muaj txiaj ntsig zoo hauv cov tshuab uas muaj kev pheej hmoo ntawm hluav taws kub hnyiab.

Summary – Hydraulic Fluid vs Hydraulic Oil
Hydraulic roj yog ib hom ntawm cov kua dej hydraulic. Hydraulic kua txo cov teeb meem cuam tshuam ntawm hydraulic roj xws li flammability ntawm high-pressure tej yam kev mob. Qhov sib txawv ntawm cov kua dej hydraulic thiab cov roj hydraulic yog tias cov kua dej hydraulic muaj txiaj ntsig zoo hauv kev sib kis tsis siv neeg hauv lub tsheb thaum cov roj hydraulic tsis tuaj yeem siv rau lub hom phiaj no.
