| Abstract: | This paper analyses the failure modes and problems when working and safety brakings in existent hydraulic station. A highly reliable hydraulic system was developed from safe and reliable angles. It is Provided with some addional safe and protective functions, such as multi-line returning oil when safety braking, fault monitoring for the electromagnetic valves, and protection of high residual oil pressure, etc., and improves the adjusting oil pressure function of working braking and electric control system. So the reliability of the whole braking system is improved. |
