Mixing shaft stop failure and of Sicoma concrete mixer

1. Reasons for the agitator shaft failure

In the process of using Sicoma concrete mixer, the bearing is a relatively common part, and the problem of the stalling of the stirring shaft also occurs from time to time. The main reasons for this phenomenon are as follows:

First, the concrete mixer has a very high speed during operation. During the operation, if the load exceeds its own load, the pre-rotation speed of the mixer will be significantly slower. Seriously, it will affect the effect of mixing. If the operator does not pay more attention to this problem, or does not take any solution, it will inevitably cause damage to sicoma twin shaft mixer and directly affect the smooth progress of the construction project.

Second, there is a large volume of foreign matter between the stirring blade and the inner wall of the can. The mixer is prone to internal plugging during operation. If a large foreign matter occurs, it is easy to affect the smooth operation of the mixing blade and the inner wall of the tank. If there is a significant change in the operating conditions of these two parts, the work of the mixing machine will be seriously affected.

Third, the motor’s tape is too loose. It is common for concrete mixers to loosen the tape during construction.

The looseness of the motor tape is an important factor in reducing the transmission power, and the stirring work cannot be performed smoothly.

2. Maintenance of the stalling failure

If the concrete mixer is overloaded, the operator needs to adjust the operating condition reasonably to ensure that the concrete feed volume is consistent with the mixer load. At the same time, it is also possible to control the amount of feed while unloading the excess load. During the operation of the concrete mixing blade, if there is a phenomenon of foreign matter clogging, it is necessary to control the degree of friction in the operation. Control the appearance of harsh sounds. At the same time, the corresponding operator is required to observe the fault of the machine and directly find the fault.

In the process of handling the motor loose tape , the operator should check the parts where the motor tape is loose, especially when the mixer stops. To stop the machine in time, re-adjust the device, straighten the tape, and continue to run after checking.
