When we operate the shotcrete machine daily, we often encounter such and other problems. Therefore, our shotcrete machine company has made a small summary of these problems, as follows.
1. The pressure of the conveying air flow is too low. If this situation is encountered, we should immediately stop the motor and air supply pipeline of the sprayer. If the rotor is blocked during the stop, we should disassemble the air inlet pipe and the upper air pipe, and clean the material cavity with a brush. clean.
2. The particle size of the aggregate is too large. In this case, we should stop the rotation of the shotcrete machine, close the air valve, then remove the feed pipe from the elbow, and open the air valve, then blow out the rotor material, and then check Whether the feeding pipe is blocked, finally connect the feeding pipe to the elbow and blow it out with pressurized air.
3. The section of the air inlet pipe is small, and the air supply of the compressor is small. At this time, we should replace the spraying machine with a large air duct and a large-capacity compressor.
4. The moisture content of the dry mix is too large. At this time, we should close the air valve of the shotcrete machine, clean the elbow and rotor cavity, and minimize the water-cement ratio of the mixture.
