Hydraulic hoses yog lub luag hauj lwm rau kev thauj cov siab - hydraulic kua nyob rau hauv hydraulic systems. Lawv xaiv cov khoom siv ncaj qha cuam tshuam rau kev ua haujlwm siab, ua haujlwm ntev, kev hloov pauv ib puag ncig, thiab kev nyab xeeb ntawm kev ua haujlwm tag nrho. Raws li kev ua haujlwm sib txawv thiab cov xwm txheej hauv xov xwm, kev xaiv cov khoom siv suab nrov tuaj yeem ua kom muaj kev ua haujlwm zoo thaum txuas cov kav dej thiab txo cov nqi tu.
Hydraulic hoses feem ntau muaj peb ntu: ib txheej roj hmab sab hauv, ib txheej reinforcing, thiab txheej tiv thaiv txheej. Cov ntaub ntawv ntawm txhua txheej yuav tsum ua hauj lwm ua ke kom tau raws li cov kev xav tau ntawm kev ua tau zoo xws li roj tsis kam, siab tsis kam, kub tsis kam, tiv thaiv kev laus, thiab hnav tsis kam. Cov roj hmab sab hauv feem ntau siv cov roj hmab tshwj xeeb xws li roj hmab nitrile (NBR), hydrogenated nitrile roj hmab (HNBR), lossis fluororubber (FKM). Ntawm cov no, NBR muaj kev tiv thaiv zoo rau cov roj ntxhia thiab tus nqi nruab nrab, ua rau nws haum rau cov pa roj hydraulic ib puag ncig; HNBR muaj kev tiv thaiv kev laus zoo dua thiab tiv thaiv tshav kub hauv siab - kub thiab sulfur- muaj roj; thiab FKM tuaj yeem tiv taus ntau yam tshuaj lom neeg thiab qhov kub thiab txias, feem ntau siv rau hauv cov xwm txheej tshwj xeeb lossis corrosive.
Cov txheej txheem txhawb nqa yog qhov tseem ceeb hauv kev txiav txim siab lub siab - cov kabmob muaj peev xwm ntawm cov raj, thiab feem ntau siv cov qauv siab - lub zog steel hlau braiding lossis winding. Braided khaubncaws sab nraud povtseg muab zoo yooj thiab nruab nrab siab- bearing muaj peev xwm, haum rau me me mus rau nruab nrab ntws thiab siab circuits; cov khaubncaws sab nraud povtseg, nrog cov txheej txheem ntau dua thiab qhov ntom ntom, txhim khu kev ua haujlwm siab thiab tuaj yeem ua tau raws li qhov xav tau ntawm ultra-siab hydraulic systems. Lub braiding los yog winding lub kaum sab xis thiab qhov ceev yuav tsum tau optimized raws li kev ua hauj lwm siab thiab mem tes yam ntxwv kom sib npaug zog thiab elasticity.
Cov khoom siv sab nrauv yuav tsum tiv thaiv ib puag ncig corrosion thiab kev puas tsuaj, feem ntau siv neoprene (CR), polyurethane (PU), lossis thermoplastic elastomers (TPE). CR muaj kev sib xyaw ua ke ntawm huab cua tsis kam, ozone tsis kam, thiab kev puas tsuaj, dav siv hauv cov khoom siv sab nraum zoov thiab engineering; PU ua tau zoo nyob rau hauv kev puas tsuaj, haum rau siab -kev sib txhuam lossis pob zeb; TPE yog lub teeb yuag thiab rov ua dua tshiab, tsim nyog rau ib puag ncig thiab hnyav- cov ntawv thov nkag siab.
Thaum xaiv cov khoom siv, qhov ntsuas kub ntawm kev khiav hauj lwm, hom kua dej, mem tes zaus, thiab muaj peev xwm raug tshuaj lom neeg yuav tsum tau txiav txim siab. Piv txwv li, nyob rau hauv cov cheeb tsam txias, cov roj hmab formulations uas tsis zoo - kub elasticity yuav tsum tau xaiv, thaum nyob rau hauv siab - kub, lub thermal stability ntawm hose thiab reinforcing txheej yuav tsum tau guaranteed. Nyob rau tib lub sijhawm, kev sib raug zoo ntawm cov khoom sib txawv yog qhov tseem ceeb kom tsis txhob muaj kev ua haujlwm degradation los ntawm o lossis degradation tshwm sim ntawm cov hose thiab cov kua dej hydraulic.
Kev tshawb fawb ntawm hydraulic hose cov ntaub ntawv tsis tsuas yog ua tau raws li qhov system siab thiab xov xwm yuav tsum tau ua tab sis kuj tswj kev ua haujlwm ruaj khov nyob rau hauv ib puag ncig nyuaj thiab ntev - lub sij hawm voj voog, yog li muab kev lees paub zoo rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm hydraulic system.
