我公司1台压路机在柴油机熄火后,其制动系统的压力不到1h即迅速从0.8MPa降到0,不能保证该机可靠工作。由于此前该机在正常工作时制动系统气压正常,初步判断其制动系统可能存在漏气。检查该机制动系统连接管路,结果未发现管路连接处和储气筒存在漏气问题。由压路机正常工作过程中制动系统压力正常,可以排除加力器、制动阀和气压调节阀存在问题的可能,唯一可
After a diesel engine is turned off, the pressure of the brake system of a roller of our company drops rapidly from 0.8MPa to 0 in less than 1h, which can not guarantee the reliable operation of the engine. Due to the normal working hours before the normal braking system pressure, the initial judgment of the brake system may be leaks. Check the machine brake system connecting pipe, the results did not find the pipe connection and the gas cylinder leakage problems. By normal operation of the roller brake system pressure is normal, you can rule out the booster, brake valve and pressure regulating valve may be the problem, the only
