1.气制动系统密封性检验 (1)贮气系统密封性 在贮气系统气压力600kPa的情况下,将样车熄火停放2h,若系统气压不低于500kPa,则判为贮气系统密封合格;否则,为不合格。 (2)制动系统密封性 样车熄火,在气压为600kPa情况下,将制动踏板踏到底,待气压稳定后观察,经5min时间,若气压不下降,则判为制动系统密封合格;如气压下降,但下降量不超过50kPa,则判为制
1. Gas brake system sealing test (1) gas storage system sealing Gas storage system in the case of pressure 600kPa, the sample vehicle parked flame 2h, if the system pressure is not less than 500kPa, then sentenced to gas storage system seal Eligible; otherwise, unqualified. (2) Braking System Sealing The sample vehicle is flame-extinguished. When the pressure is 600kPa, the brake pedal is stepped on until the air pressure is stable. After 5 minutes, if the air pressure does not decrease, the brake system is judged to be sealed. If the pressure drops, but the amount of decline does not exceed 50kPa, the sentence for the system
