For example, there may be noise in the motor or the overflow valve. First of all, let's take a look at the noise of the plunger or motor?

自上料搅拌车吸空现象时造成液压泵噪音过高的主要原因之一。当油液中混入空气后，很容易在高压区形成气穴现象，并以压力波的形式传播，造成油液震荡，导致系统产生气蚀噪音，主要原因有两方面；液压泵内部元件过度磨损，如柱塞泵的缸体与配流盘、柱塞孔等配合件的磨损、拉伤，使液压泵内泄漏严重，当液压泵输出高压、小流量油液时将产生流量脉动，引发较高噪音。此时可适当加大先导系统变量的机构偏角，以改善内泄漏对泵输出流量的影响。液压泵的伺服阀阀芯、控制流量的活塞也会因局部磨损、拉伤，使活塞在移动的过程中脉动，造成液压泵输出流量和压力的波动，从而在泵出口产生较大振动和噪音。此时可对磨损、拉伤严重的元件进行刷镀研配或更换处理。

It is one of the main reasons for the high noise of hydraulic pump caused by the phenomenon of suction of self loading mixer. When the oil is mixed with air, it is easy to form cavitation in the high-pressure area and propagate in the form of pressure wave, causing oil shock and causing cavitation noise in the system. There are two main reasons: excessive wear of internal components of hydraulic pump, such as wear and tear of matching parts such as cylinder block of plunger pump, port plate and plug hole, makes serious leakage in hydraulic pump High pressure, small flow of oil will produce flow pulsation, causing high noise. At this time, the deflection angle of the pilot system variable can be increased to improve the influence of internal leakage on the pump output flow. The servo valve core of the hydraulic pump and the piston controlling the flow rate will also have local wear and tear, which will cause the piston to pulsate in the process of moving, resulting in the fluctuation of the output flow and pressure of the hydraulic pump, resulting in greater vibration and noise at the pump outlet. At this time, the components with serious wear and tear can be prepared by brush plating or replacement.
            

液压泵流盘也是引发噪音的重要元件之一。配流盘在使用中因表面磨损或油泥沉积在卸荷槽开启处，都会是卸荷槽变短而改变卸荷位置，产生困油现象，继而引发较高噪音。

The flow plate of hydraulic pump is also one of the important components that cause noise. When the valve plate is in use, due to surface wear or sludge deposition at the opening of the unloading groove, the unloading position will be changed due to the shortening of the unloading groove, resulting in oil trapping phenomenon, and then causing higher noise.

溢流阀也会产生噪音，其原因主要有三个方面：一是，油液中混入空气，在先导阀前腔内形成气穴现象而引发噪音。此时只要排尽空气就可噪音问题；二是，针阀过度磨损，致使针阀锥面与阀座不能密合，造成先导流量不稳定、产生压力波动而引发噪音，此时更换针阀或及时修理即可；三是，先导阀因弹簧疲劳变形造成其调压功能不稳定，使得压力波动过大而引发噪音，此时应更换弹簧。

There are three main reasons for the noise of relief valve: first, air is mixed into the oil, which causes the noise due to cavitation in the front chamber of pilot valve. At this time, as long as exhaust air can solve the problem of noise; second, excessive wear of the needle valve, resulting in the needle valve cone and valve seat can not be closed, resulting in the pilot flow instability, pressure fluctuations and cause noise, at this time replace the needle valve or repair in time; third, the pilot valve due to spring spring fatigue deformation caused by its pressure regulating function is not stable, so that the pressure fluctuation is too large and cause noise The spring should be replaced.

自上料搅拌车的管路也会产生噪音，原因多半是管路死弯过多或固定卡子松脱。所以在管路的布置上应该避免死弯，对松脱的卡子须及时拧紧。

The pipeline from the loading mixer will also produce noise, which is mostly due to excessive dead bending of the pipeline or loosening of the fixing clip. Therefore, dead bending should be avoided in the pipeline layout, and the loose clips must be tightened in time.
