1、 Can body vibration

拌和车的罐体在轴线上，正常状态下罐体运行稳定。由于积料或料工作不均匀，就会导致罐体偏移，罐体工作中就会呈现颤动。由于积料造成的颤动故障具体表现在：1，罐体颤动呈现周期性变化 2，罐体转动一周颤动不超越两次。假如罐体颤动没有规则，能够查看油箱油液是否浑浊，减速机是否有损坏导致油液混入金属颗粒。

The center of gravity of the tank body of the mixer is on the axis, and the operation of the tank body is stable under normal conditions. Because of the unevenness of the accumulated material or the material work, the center of gravity of the tank body will shift, and the tank body will vibrate during the work. The vibration faults caused by the accumulation of materials are as follows: 1. The vibration of the tank body changes periodically; 2. The vibration of the tank body does not exceed twice in one cycle. If the tank vibrates irregularly, check whether the oil in the tank is turbid and whether the reducer is damaged and the oil is mixed with metal particles.

二、噪音

2、 Noise

首要，液压体系本身在输出功率时就会有声响，尤其在大功率输出时，所以假如空车就有大功率输出的规则性噪音时，应排除罐体严峻积料的或许。假如是沉重的轰鸣声，应考虑空气混入的要素；假如声响比较尖锐，又要分高压溢流噪音和机械原因导致的噪音，在重载时，假如负载过大并超出体系溢流阀的设定值，体系会溢流，此时会发生急剧的嚣叫声，同时随同油温敏捷升高。机械原因的噪音往往会随着发动机的转速提高而发生。

First of all, the hydraulic system itself will have sound when it outputs power, especially when it outputs high power, so if the empty car has regular noise of high power output, it is necessary to eliminate the possibility of severe material accumulation in the tank. If it is a heavy roaring sound, the elements of air mixing should be considered; if the sound is sharp, the high-pressure overflow noise and the noise caused by mechanical reasons should be divided. In case of heavy load, if the load is too large and exceeds the set value of the system overflow valve, the system will overflow. At this time, a sharp roaring sound will occur and the oil temperature will rise rapidly. Mechanical noise often occurs as the engine speed increases.

三、重载无力

3、 Heavy load weakness

假如混凝土拌和车呈现重载无力的状况，能够首要考虑拌和车车龄。拆开滤芯查看，假如在滤芯内发现金属粉末、铜沫甚至大块金属物，即可判定液压泵或马达磨损。

If the concrete mixer is in the condition of heavy load and weak, the age of mixer can be considered first. Disassemble the filter element for inspection. If metal powder, copper foam or even large metal objects are found in the filter element, it can be determined that the hydraulic pump or motor is worn.
