The feeding pipe is the material conveying device of the wet shotcrete machine. With the help of the feeding pipe, long-distance wet spraying operation can be realized. However, when using the wet shotcrete machine, the feeding pipe is often blocked. Regarding the cause of the blockage and the troubleshooting method, Next, the editor will discuss the reasons for the pipe blockage of the wet shotcrete machine!
1. Causes of blockage
1. The wet shotcrete machine encounters a temporary shutdown during operation, and the shutdown time is too long without clean water. 2. The feeding pipe was not cleaned after the last wet spraying. 3. There are too few fine-grained materials in the material, and the slurry leaks from the joint. 4. The material is too thick or unevenly stirred.
2. Elimination method
1. Use water to flush out the blocked material in the conveying pipe, and rinse it several times until the conveying pipe returns to normal. In addition, first lubricate the pipe with white ash when starting the wet shotcrete machine again. 2. After each wet spraying, clean the pipes of the wet shotcrete machine with clean water and then stop the machine. 3. Check the pipeline condition frequently to prevent material leakage. 4. Before conveying, mix the materials in strict accordance with the specified consistency before conveying.
