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?

自上料攪拌車吸空現(xiàn)象時造成液壓泵噪音過高的主要原因之一。當油液中混入空氣后，很容易在高壓區(qū)形成氣穴現(xiàn)象，并以壓力波的形式傳播，造成油液震蕩，導致系統(tǒng)產生氣蝕噪音，主要原因有兩方面；液壓泵內部元件過度磨損，如柱塞泵的缸體與配流盤、柱塞孔等配合件的磨損、拉傷，使液壓泵內泄漏嚴重，當液壓泵輸出高壓、小流量油液時將產生流量脈動，引發(fā)較高噪音。此時可適當加大先導系統(tǒng)變量的機構偏角，以改善內泄漏對泵輸出流量的影響。液壓泵的伺服閥閥芯、控制流量的活塞也會因局部磨損、拉傷，使活塞在移動的過程中脈動，造成液壓泵輸出流量和壓力的波動，從而在泵出口產生較大振動和噪音。此時可對磨損、拉傷嚴重的元件進行刷鍍研配或更換處理。

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.
            

液壓泵流盤也是引發(fā)噪音的重要元件之一。配流盤在使用中因表面磨損或油泥沉積在卸荷槽開啟處，都會是卸荷槽變短而改變卸荷位置，產生困油現(xiàn)象，繼而引發(fā)較高噪音。

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.

溢流閥也會產生噪音，其原因主要有三個方面：一是，油液中混入空氣，在先導閥前腔內形成氣穴現(xiàn)象而引發(fā)噪音。此時只要排盡空氣就可噪音問題；二是，針閥過度磨損，致使針閥錐面與閥座不能密合，造成先導流量不穩(wěn)定、產生壓力波動而引發(fā)噪音，此時更換針閥或及時修理即可；三是，先導閥因彈簧疲勞變形造成其調壓功能不穩(wěn)定，使得壓力波動過大而引發(fā)噪音，此時應更換彈簧。

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.

自上料攪拌車的管路也會產生噪音，原因多半是管路死彎過多或固定卡子松脫。所以在管路的布置上應該避免死彎，對松脫的卡子須及時擰緊。

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.
