Cov Ntsiab Cai Kev Tshawb Fawb Tom Qab 100 Thib Ob
Lub sijhawm 100-thib ob lub sijhawm rau electrofusion pob qij txha yog hais txog lub sijhawm ua haujlwm ntawm cov cua sov. Thaum tam sim no dhau los ntawm cov hlau tsis sib haum, qhov chaw sib cuag ntawm cov yeeb nkab thiab qhov sib txuas ua tiav peb theem: 40 vib nas this ntawm preheating thiab softening, 30 vib nas this ntawm melting thiab bonding, thiab 30 vib nas this ntawm txias thiab teeb. Lub sijhawm no tau rov qab xyuas dua los xyuas kom meej tias cov khoom siv polyethylene cov saw hlau molecular tau hloov kho tag nrho, tsim cov txheej txheem sib txuas kom muaj zog dua li cov khoom siv hauv paus.
Tej yam kev thov Scenarios
Kev Siv Dej Hauv Nroog thiab Dej Dej: Rau kev kho cov kav dej hauv av hauv av, kev xau - kev sib txuas dawb tuaj yeem ua tiav sai sai hauv 100 vib nas this.
Gas Pipelines: Explosion-cov ntaub ntawv pov thawj tsim kom muaj kev tswj xyuas lub sijhawm cua sov.
Industrial Pipelines: Corrosion-cov kav dej tiv taus hauv cov chaw ua haujlwm tshuaj lom neeg siv cov txheej txheem vuam segmented.
Kev ceev faj txog kev ua haujlwm
Thaum lub ambient kub qis dua 5 degree, lub vuam lub sij hawm yuav tsum tau ncua los ntawm 20%.
Voltage fluctuations ntawm ± 10% tuaj yeem ua rau txo qis hauv vuam zoo.
Kev tshem tawm tsis tiav ntawm oxide txheej ntawm cov yeeb nkab kawg yog qhov ua rau 80% ntawm qhov tsis ua haujlwm.
