When the mortar spraying machine conveys and sprays the mortar, it may cause pipe blocking due to various reasons. The common pipe blocking phenomenon is basically due to the problem of mortar formula, the segregation of the mortar spraying machine , or the residence time in the pipeline is too long, and the working pressure is too high. These reasons are caused, so today we will take a closer look at these causes of blockage.
The plugging of mortar formulation problems generally occurs in the early stages of use. Due to the unsuitable mix of mortar, the lack of fluidity of the mortar causes the frictional force of the mortar to flow too much and cause the plugging of the pipe. The solution to this problem is to adjust the type or amount of the admixture, and at the same time, better fluidity can be obtained by adjusting the gelling material. After the adjustment, it needs to be tested to verify whether it can be used.
The phenomenon of mortar isolation generally occurs in the middle of spraying construction. It is due to the separation of the mortar at the bottom of the mortar bulk tank, which changes the properties of the mortar material. The blocked pipe caused by this reason can control the storage surplus of the bulk tank. When the mortar at the bottom of the bulk tank is less It should be stopped at 5 tons. For the mortar that has been segregated, you can try to increase the consistency of the mortar to prevent the bottom spraying.

The principle of mortar plugging caused by too long residence time in the pipeline is relatively simple. This requires users to pay attention to minimizing downtime. If the downtime is really required, the remaining mortar in the equipment should be used up first. Shut down and clean pipes.
The last one is the phenomenon of pipe plugging caused by high pressure during mortar conveying and spraying. In addition to the problems mentioned above, the pressure increase may be caused by too long conveying distances and clogging of foreign objects in the mortar spray machine. It usually occurs at the outlet of the slurry pipe. As the pressure increases, part of the water in the mortar leaks out through the discharge port. If there is a problem with the seal of the slurry pipe joint, it will also cause the mortar to leak water at the interface, which will cause blockage. Phenomenon occurs, but this phenomenon is a precursor to plugging the pipe. Generally, there will be a significant decrease in the amount of mortar transport and spraying, and the working pressure will gradually increase.
