1、 Can body vibration
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.
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.
3、 Heavy load weakness
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.
