自动搅拌车正常的噪音是没有问题的,但假如搅拌车发生不正常的噪音,那便是车辆的某个部位出现问题了,在自拌混凝土搅拌车,液压体系出现异常噪音比较多,一起来看看搅拌车液压体系的噪音解决办法。搅拌车液压体系发生噪音主要是先导阀功用不稳定构成的,便是先导阀前腔压力高频振荡引起空气振荡而发生的噪音。自动搅拌车液压溢流阀引发噪音的原因及解决办法:
Automatic mixer normal noise is no problem, but if the mixer abnormal noise, it is a part of the vehicle problems, in the self mixing concrete mixer, hydraulic system abnormal noise more, let's see the mixer hydraulic system noise solutions. The noise of the mixer hydraulic system is mainly caused by the unstable function of the pilot valve, that is, the noise caused by the air oscillation caused by the high frequency oscillation of the pressure in the front chamber of the pilot valve. Causes and solutions of noise caused by hydraulic relief valve of automatic mixer truck:
1. 油液中混入空气,在先导阀前腔内构成气穴现象而引发高频噪音,此刻要做的便是及时的排尽空气并防止外界空气的进入。
1. Air mixed in the oil will form cavitation phenomenon in the front chamber of the pilot valve and cause high-frequency noise. What we need to do now is to exhaust the air in time and prevent the outside air from entering.

2. 针阀在使用过程中因频频敞开而过度磨损,使针阀锥面与阀座不能密合,构成先导流量不稳定,发生压力动摇而引发噪音,此刻应及时修补或许替换针阀。
2. The needle valve is excessively worn due to frequent opening during use, so that the cone surface of the needle valve and the valve seat can not be closed, resulting in unstable pilot flow and noise caused by pressure fluctuation. At this moment, the needle valve should be repaired or replaced in time.
3. 先导阀因绷簧疲劳变形构成其调压功用不稳定,使得压力动摇大而引发噪音,此刻需求替换绷簧。
3. The pressure regulating function of the pilot valve is unstable due to the fatigue deformation of the tension spring, which makes the pressure fluctuate greatly and causes noise. At this moment, the tension spring needs to be replaced.
自拌混凝土搅拌车液压油缸噪音原因及解决办法:
Causes and solutions of hydraulic cylinder noise of self mixing concrete mixer truck:
1. 油液中混入空气或许液压缸中空气未彻底排尽,在高压作用下发生气穴现象而引发较大噪音,此刻应尽快排尽空气。
1. Air is mixed in the oil, or the air in the hydraulic cylinder is not completely exhausted. Cavitation occurs under the action of high pressure, which causes large noise. At this moment, exhaust the air as soon as possible.
2. 缸头油封过紧或活塞杆曲折,在运行过程中也会因为别劲而发生噪音,此刻有必要替换油封或许校正活塞杆。
2. If the oil seal of the cylinder head is too tight or the piston rod is bent, the noise will also occur during the operation because of other strength. At this moment, it is necessary to replace the oil seal or correct the piston rod.
