摘要
对KZW-A型空重车自动调整装置故障引起制动缸缓解不良的原因进行了分析和试验验证,发现减小限压阀阀芯弹簧压力可大幅消除传感阀触杆排气孔堵塞引起的制动缸缓解不良故障。
The causes to bad release of braking cylinders caused by troubles in the KZW-A empty and load automatic brake equipment are analyzed and verified by testing.It is found out that reduction of the pressure of core spring in the pressure limiting valve can greatly eliminate the trouble of bad release of braking cylinders caused by blocking of the exhaustion hole of the sensor contact rod.
