如果搅拌机的减震器出现故障或问题，应先检查减震器是否有漏油现象，按下减震器，然后松开，如果搅拌机有两到三次跳跃，说明减震器良好。

If the shock absorber of the mixer fails or has problems, first check whether the shock absorber has oil leakage, press the shock absorber, and then release it. If the mixer jumps for two or three times, it indicates that the shock absorber is in good condition.

搅拌车在慢速行驶时紧急制动时，如果车辆振动严重，说明减振器有问题。必须拆下减震器，将其竖起，将下连接环卡在台钳上，并将减震器杆拉压数次。

If the mixer truck vibrates seriously during emergency braking at a slow speed, it indicates that there is a problem with the shock absorber. The shock absorber must be removed, erected, the lower connecting ring clamped in a vice, and the shock absorber rod pulled and pressed several times.

这时，应该有稳定的阻力，向上拉的阻力应该大于向下拉的阻力。如果电阻不稳定或没有电阻，如果振动器内缺油或阀门零件损坏，则可能是电阻降低，应停止修理或更换零件，并立即送零件修理。

At this time, there should be stable resistance, and the resistance to pull up should be greater than that to pull down. If the resistance is unstable or there is no resistance, if there is a lack of oil in the vibrator or the valve parts are damaged, the resistance may be reduced. Stop repairing or replacing the parts and send them to repair immediately.

油封和密封垫圈可能损坏失效，应更换新的。如果仍不能漏油现象，则拔出减震器。如果感觉有卡或重量不同，应进一步检查活塞与气缸间隙是否过大，减震器活塞连杆是否弯曲，活塞连杆与气缸表面是否有划伤或拉伤痕迹。

The oil seal and sealing washer may be damaged and invalid, and they should be replaced with new ones. If the oil leakage cannot be eliminated, pull out the shock absorber. If there is a card or the weight is different, further check whether the clearance between the piston and the cylinder is too large, whether the piston connecting rod of the shock absorber is bent, and whether the piston connecting rod and the cylinder surface are scratched or pulled.

如果上述检查正常，应进一步拆卸减振器，检查混凝土搅拌机活塞与筒体的配合间隙是否过大，筒体是否拉紧，阀密封是否良好，阀瓣与阀座配合是否紧密，伸出量是否过大混凝土搅拌机减震器弹簧太软或断裂。应根据情况采用磨削或更换零件的方法。

If the above inspection is normal, the vibration damper shall be further disassembled to check whether the fitting gap between the piston and the cylinder of the concrete mixer is too large, whether the cylinder is tensioned, whether the valve seal is good, whether the valve disc fits closely with the valve seat, and whether the extension is too large. The vibration damper spring of the concrete mixer is too soft or broken. The method of grinding or replacing parts shall be adopted according to the situation.

另外，自动上料搅拌车的减振器在实际使用中会产生噪音，主要是由于自动上料搅拌车的减振器与钢板弹簧、车架或轴发生碰撞，橡胶垫损坏或脱落，减振器防尘筒变形，缺油，等，找出原因并修复。

In addition, the vibration damper of the automatic feeding mixer will produce noise in actual use, mainly because the vibration damper of the automatic feeding mixer collides with the leaf spring, frame or shaft, the rubber pad is damaged or falls off, the dust cylinder of the vibration damper is deformed, lack of oil, etc., find out the causes and repair them.
