Fuel Pipe Pressure Cycle Test Bench

Fuel Pipe Pressure Cycle Test Bench yog siv los simulate qhov ntws ntawm cov roj los yog ethylene glycol: dej (50:50) ntawm ib lub siab thiab qhov kub thiab txias hauv qhov kev ua haujlwm tiag tiag ntawm kev kub siab, tsis tshua muaj siab, kev vibration siab, thiab kub ntawm automotive txias dej yeeb nkab thiab roj yeeb nkab, thiab saib xyuas seb cov yeeb nkab puas tuaj yeem ua tau raws li qhov kev ua haujlwm, uas yog siv los ua kom muaj lub voj voog siab thiab tsis tshua muaj siab, lub voj voog nruab nrab ntawm qhov kub thiab txias, thiab kev co kev sim siab ntawm cov roj yeeb nkab thiab cov kav dej.
