Taw qhia ntawm tes tsim dav arch roj hmab expansion sib koom ua ke:
Feem ntau cov neeg tsis paub nrog dav arch rubber mos pob qij txha. Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam, qee zaum tsis yog - qauv roj hmab expansion pob qij txha yuav tsum tau siv nyob rau hauv cov xwm txheej tshwj xeeb, thiab tus nqi ntawm kev ua pwm tshiab lossis hloov pwm yog kim heev. Yog li ntawd, txhawm rau txuag nqi, tib neeg xav txog kev siv cov pob qij txha txuas ntxiv los hloov cov pwm ruaj khov vulcanized roj hmab expansion pob qij txha. Tom qab ntawd, ntau tus neeg yuav nug, Dab tsi yog txhais tes tsim dav arch rubber expansion sib koom ua ke thiab nws cov txheej txheem tsim khoom yog dab tsi? tes tsim dav arch roj hmab expansion sib koom ua ke yog ib tug tubular roj hmab ib feem ntawm lub puab thiab sab nrauv roj hmab, qaum ntaub thiab steel nplhaib, uas yog ua los ntawm tes, vulcanized ntawm kub thiab siab siab, thiab ces ua ke nrog hlau flange los yog xoob lub tes tsho ntawm parallel. sib koom. Cov khoom no ua rau siv cov khoom zoo ntawm cov roj hmab, xws li elasticity siab, siab roj tsis kam, nruab nrab tsis kam, huab cua tsis kam thiab hluav taws xob tsis kam, tuaj yeem txo kev co thiab suab nrov, thiab tuaj yeem them nyiaj rau thermal expansion thiab txias contraction los ntawm qhov kub thiab txias. Lub pob loj yog hloov tau thiab muaj ntau haiv neeg, thiab tuaj yeem kho raws li qhov xav tau. Nws yog dav siv nyob rau hauv ntau yam pipeline systems.
China factory for wide arch rubber expansion joint. have material EPDM, NBR,etc, They are all hand built by our workers.
Multiple of rubber impregnated high strength polyester or nylon tire cord form the first pressure reinforcement over the tube. Arch swell in response to pressure and arch migration are virtually eliminated by criss-crossed layers of reinforcement that pass over the arch and around steel or ductile iron rings embedded on both sides at the base of the arch.
rubber expansion joint's Body arch is controlled by high strength fabric or spiral steel wire. Large diameter expansion joints are often built with steel rings in place of the wire when in addition to internal pressure, external pressure resistance is important.
Peb txais ntau hom kev hloov kho
Lub siab sab nraud tuaj yeem yog los ntawm kev faus tob, ntiav embankment nyob rau hauv txoj kev los yog cov pob qij txha hauv cov tso tsheb hlau luam.
Kev tsim cov txheej txheem ntawm winding rubber saj zawg zog sib koom ua ke: nyob rau hauv cov txheej txheem ntawm cov roj hmab saj zawg zog sib koom ua ke, sab hauv yog tsis ntshiab roj hmab, tab sis nrog woven mesh. Ua kom tsim nyog cov roj hmab cov pob qij txha, cov roj hmab sab hauv lub raj khoob yog muab tso rau ntawm qhov chaw ua haujlwm, qhov chaw ntawm lub raj tub ntxhais yog coated nrog tus nqi tsim nyog ntawm kev sib cais, thiab tom qab ntawd cov roj hmab txheej hauv lub raj tsis muaj qhov tsim nyog. cua los tes tsho lub hauv paus. Tom qab cov tub ntxhais yog sheathed, nws yuav tsum tau txheeb, tshuaj xyuas, qhov loj me thiab khaws cia, thiab xa mus rau cov txheej txheem tom ntej rau winding. Txiav txim siab cov ceg ntoo, lub qhov ncauj puab thiab winding stroke ntawm cov khoom siv winding raws li kev tsim khoom. Ua ntej winding cov roj hmab hloov tau yooj yim sib koom ua ke ntawm thawj cov hlau hlau, cov hlau hlau yuav tsum dhau los ntawm cov hlau lead, nro haum, ntu ntu thiab ua lub qhov ncauj raws li cov lus qhia tawm, thiab tom qab ntawd muab nruj nreem khi ntawm cov yeeb nkab txhuas ntawm lub tsheb laij teb nrog cov nplaum. daim kab xev raws li winding kev taw qhia. Pib lub tshuab winding kom ua rau cov yeeb nkab txuas mus rau pem hauv ntej maj mam, thiab kho cov traction ceev los ntawm tus tswv xeev kom lub winding stroke raws li qhov yuav tsum tau ua. Tom qab lub winding stroke raug kho, txhim kho cov yeeb yaj kiab nruab nrab, Thiab cov yeeb nkab dawb paug nrog cov txheej tiv thaiv braided tau qhia (qhov saum npoo tau raug wiped huv si nrog hnyav), lub winding ntawm steel hlau roj hmab mos sib koom yuav pib. Thaum pib winding, qhov ceev yuav tsum maj mam nce, thiab tom qab ncav cuag ib qho kev ceev, cov yeeb yaj kiab nruab nrab yuav tsum tau muab tso rau hauv cov txheej txheem winding tib lub sijhawm. Thaum lub sij hawm winding, steel hlau nro yuav tsum zoo ib yam, cov hlau hlau yuav tsum tau teem rau ntawm lub raj dawb paug nyob rau hauv kev txiav txim, tusyees thiab tiaj tus, thiab cov yeeb nkab nias ntawm lub traction ntaus ntawv yuav tsum tsim nyog thiab tsis nruj heev, tiv thaiv deformation ntawm cov yeeb nkab dawb paug.
Raws li qhov xwm txheej twg yuav tsis yog - cov qauv roj hmab hloov pauv tau siv tau?
1. Qhov ntev yog qhov sib txawv heev ntawm cov molded roj hmab muag kev sib txuas, uas yog luv luv los yog ntev heev.
2. Cov kab me me cov neeg siv khoom xav kom lub ntsej muag kawg yuav tsum tau ntim tag nrho. Nws yuav tsum tau muab sau tseg tias buckle groove roj hmab muag kev sib txuas yog qhov nyuaj rau qhov txhab.
3. Qhov sib txawv ntawm lub qhov drilling thiab tus qauv yog qhov loj heev, tshwj xeeb tshaj yog qhov chaw nruab nrab ntawm qhov deb yog qhov loj heev, thiab qhov tuag tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.
