Raws li ntau hom tsheb nres, tuaj yeem faib ua hydrauliccov yeeb nkab nres, pneumatic nres hose thiab nqus tsev nres hose. Raws li nws cov khoom siv, nws muab faib ua roj hmab nres hose, nylon nres hose thiab PTFE nres hose.
Cov roj hmab nres hose muaj qhov zoo ntawm lub zog tensile muaj zog thiab yooj yim installation, tab sis qhov tsis zoo yog tias qhov chaw yooj yim rau kev laus tom qab siv ntev.
Yog tias qhov kub qis, lub zog tensile ntawm nylon nres hose yuav qaug zog, yog tias cuam tshuam los ntawm cov rog sab nraud, nws yooj yim tawg
Tab sis PTFE hose muaj qhov kub thiab txias tsis kam, kub tsawg, siab siab tsis kam, hnav tsis kam, corrosion tsis kam thiab lwm yam ntxwv, lub neej ntev, tsis tas yuav hloov pauv ntau zaus. Nws tuaj yeem them rau qhov tsis zoo ntawm ob yam khoom siv.
Kev nyab xeeb, lub neej ntev, thiab kev ua tau zoo yuav tsum yog koj qhov tseem ceeb tshaj plaws. E85 lossis ethanol tau ua pov thawj tias yog roj pheej yig thiab ua haujlwm tau zoo uas tuaj yeem muab tus lej octane thiab lub zog rau cov ntawv thov uas xav tau. Tab sis cov khoom ntxiv hauv cov roj niaj hnub tuaj yeem ua rau feem ntau cov ntaub ntawv tawv thiab lwj. Qhov no tuaj yeem ua rau muaj kev xau txaus ntshai thiab tuaj yeem tawm tsw phem. Thaum cov kab roj puas tsuaj, cov khoom tsis zoo hauv cov hose tuaj yeem ua rau paug thiab txhaws cov roj injector thiab carburetor channels, cuam tshuam rau kev ua haujlwm thiab ua rau muaj teeb meem.
Qhov kev daws teeb meem zoo tshaj plaws yog cov khoom siv polytetrafluoroethylene (PTFE). PTFE yog cov khoom siv yas uas yog cov yeeb nkab roj nyias thiab sib dua tshaj plaws. Nws sib xyaw ua ke cov hlau tsis xeb 304 qib siab elastic nrog lub raj PTFE sab hauv du kom nce kev ntws, thiab cov qauv sab nraud nyuaj muab kev ywj pheej zoo kawg nkaus. Lub raj PTFE sab hauv yog tsim nyog rau kev siv nrog txhua yam roj thiab tuaj yeem tiv taus qhov kub txog li 260 degrees Celsius. Cov khoom siv tsis cuam tshuam los ntawm kev puas tsuaj ntawm roj, yog li cov pa roj tsis xau tawm.
Cov lus qhia dav dav rau cov tshuab roj:
Thaum txhim kho ib qhoPTFE hosentawm cov tsheb, khaws cov kav roj kom deb ntawm cov chaw kub, cov ntug ntse thiab cov khoom txav mus los. Ib txwm tso cai rau qhov chaw txaus rau kev txav mus los ntawm lub zog fais fab. Tshawb xyuas qhov chaw ntawm cov khoom siv ncua thiab cov khoom siv kis. Nco ntsoov xyuas cov khoom siv ncua thoob plaws hauv cov txheej txheem kom tsis txhob zawm lossis nthuav cov kav roj. Rau cov kav roj uas yooj yim rau cov khib nyiab ntawm txoj kev thiab qhov kub siab, sivPTFE roj hosesSiv cov hlau tsis xeb lossis hlau tawv los yog hlau tawv los khi. Nco ntsoov tuav cov kav dej kom nruj kom tiv thaiv kev tawg. Cov hlua khi kuj pab txo qhov kev co ntawm lwm cov khoom. Siv cov khoom sib cais kom tsim nyog thaum txuas cov vaj huam sib luag.
