With the continuous advancement of social urbanization, the demand for concrete is increasing, so the performance of the mixer of automatic mixer is required more strictly. At the same time, it is required to reduce the failure rate and the problems in the production process. The "axle holding" of the mixing machine of the concrete mixer truck is one of the common problems in the production process.
What is the meaning of "axle holding" of automatic mixer? What is the cause of this phenomenon
The shaft holding of the mixer of the automatic mixer truck refers to the binder formed by the mixing of powder, sand and liquid in the mixing process, which adheres to the mixing shaft and mixing arm, forming a very thick and hard to clean adhesive on its surface. At present, the most commonly used concrete mixing plant is the double horizontal shaft forced mixing machine, which has high efficiency and good mixing effect. However, once the shaft is held, there will be a lot of harm, and the quality of the concrete will be affected after the shaft is held by the mixing machine, so that the concrete mixing is uneven.
If the machine is not stopped and cleaned in time, there will be more and more concrete holding the shaft, which will increase the load of the mixer and increase its energy consumption. When the load exceeds a certain value, the motor of the mixing machine will be blocked due to overload, resulting in motor burnout. The service life of wear-resistant parts and shaft end seal is affected, and the wear of wear-resistant parts is accelerated. The wear of mixing arm after axle holding is very serious, which greatly reduces its service life.
Next, let's analyze the reason why the mixing machine of the automatic mixer truck "holds the shaft":
First of all, it may be due to the unreasonable design of feeding device. If the position and direction of the cement and fly ash inlet are unreasonable, a large part of the powder is put on the shaft, resulting in "shaft holding" phenomenon; the position and direction of flushing point are incorrect, or the flushing pressure is too low. When washing the tank, the concrete adhered to the mixing device can not be washed off, resulting in the phenomenon of "shaft holding"; the volume utilization rate of the mixing drum is unreasonable, and if the volume utilization rate is too small, the mixing shaft will be exposed to the concrete, and a part of the concrete adhered to it will not be stirred and will solidify on the shaft to form "shaft holding" The linear velocity of the mixing arm near the mixing shaft is too low.
