Hose feem ntau plays lub luag haujlwm tseem ceeb hauv kev ua tshuaj, tshuaj thiab zaub mov. Vim tias cov hoses thiab cov pob qij txha yog nyob rau hauv kev sib cuag ncaj qha nrog cov tshuaj los yog cov khoom noj khoom haus, kev siv cov qauv ntawm cov hoses thiab hose pob qij txha tau nce nqi los ntawm kev lag luam. Raws li peb txhua tus paub, vim muaj kev txwv ntawm kev ua hlau thiab kev ua haujlwm, qee cov khoom siv tsis tuaj yeem lossis tsis raug tso cai los cuam tshuam nrog cov khoom hlau, xws li chlorides xws li hydrochloric acid, high-purity huv kua, thiab lwm yam, yog li cov hlau. Cov pob qij txha ntawm lub hose yuav raug fluorine. Nws yog clad joint (tseem hu ua fluorine-lined joint); Qhov thib ob yog flanging ntawm hose PTFE fluorine khoom.
Cia peb saib qhov zoo thiab qhov tsis zoo ntawm ob txoj kev daws teeb meem txog PTFE-coated fittings thiab hose PTFE flanging.
Qhov zoo thiab qhov tsis zoo ntawm Shrouded Joints
Qhov zoo: txheej txheem yooj yim, tus nqi qis
tsis txaus:
1. cuam tshuam cov khoom siv thauj khoom ntws
Coupling ntawm qhov sib koom ua ke yuav txo cov khoom ntws; qhov no yog ib qho teeb meem loj hauv kev siv cov clad joint. Txhawm rau kom tsis txhob muaj kev sib cuag nrog cov khoom siv, qhov sib koom ua ke yuav tsum tau muab qhwv tag nrho, kom qhov tseeb txoj kab uas hla ntawm kev sib koom ua ke uas tuaj yeem siv rau hauv cov khoom siv thauj mus los ua me me, uas cuam tshuam kev thauj mus los ntawm cov ntaub ntawv thiab txo cov kev thauj mus los; txhawm rau daws qhov teeb meem ntws ntawm cov khoom siv thauj khoom, cov neeg siv khoom Yuav yuav ib lub taub loj dua hose, uas kuj nce nqi.
2. Yooj yim rau khaws cov ntaub ntawv
Cov coated (fluorine-lined) sib koom ua ke protrudes nyob rau hauv lub puab phab ntsa ntawm lub hose, uas yog ib qho yooj yim mus sau; qhov no kuj yog ib qho teeb meem uas cov neeg siv feem ntau qhia thaum siv cov coated sib koom ua ke. Vim hais tias cov coated sib koom ua ke muaj ib tug loj barrier nyob rau hauv lub hose, tom qab siv mus sij hawm ntev cov khoom tsub zuj zuj ntawm cov khoom yuav tsim nyob rau hauv lub puab kev sib koom ua ke ntawm cov yeeb nkab, uas tsis tsuas yog cuam tshuam rau ib txwm ntau lawm, tsub kom lub zog noj thiab kev siv zog, thiab txo cov zis, tab sis kuj. cuam tshuam rau cov khoom lag luam zoo thaum cov khoom ntim tau nce mus txog qee qhov nyiaj, thiab tseem ua rau muaj kev phom sij rau kev nyab xeeb.
3. Nws yog ib qho yooj yim los tsim cov khoom nkag
Cov ntaub ntawv permeation yog ib qho yooj yim tshwm sim ntawm kev sib cuag ntawm clad joint thiab hose.
4. Txo lub neej hose
Thaum siv lub sijhawm ntev, kev sib txuas ntawm cov coated sib koom ua ke thiab cov hose yuav ua rau muaj kev puas tsuaj rau lub hose, uas ua rau txo qis hauv kev pab cuam lub neej ntawm lub hose.
5. Cov khoom siv sib txuas ntawm qhov sib koom ua ke yog qhov sib txawv ntawm cov khoom ntawm cov phab ntsa sab hauv ntawm lub hose
Cov khoom siv txheej txheej ntawm qhov sib koom ua ke sib txawv ntawm cov khoom siv ntawm cov phab ntsa sab hauv ntawm lub hose, uas yuav ua rau muaj teeb meem tsis tsim nyog hauv kev thauj khoom.
Qhov zoo thiab qhov tsis zoo ntawm Teflon hose flanging
qhov zoo
1. Tsis lees paub qhov kev sib cuag ntawm cov khoom siv thiab cov hlau sib txuas; xyuas kom meej tias cov khoom raug xa mus rau hauv lub hose;
2. Txoj kab uas hla ntawm lub hose tseem tsis hloov, uas tsis cuam tshuam rau cov khoom siv thauj khoom ib txwm muaj;
3. Sab hauv phab ntsa yog du yam tsis muaj kev cuam tshuam thiab tsis muaj cov khoom sib txuam.
Qhov tsis zoo: cov txheej txheem siab xav tau, tus nqi yog me ntsis kim dua li cov coated (fluorine-lined) sib koom ua ke, thiab cov khoom siv nruj.
