During the use of the shotcrete machine, the faults that are usually seen are generally the following items. Here, China Coal will interpret the judgment and solution of the shotcrete machine maintenance problem for you.
In the actual operation of the shotcrete machine, there will be some rotor clogging, discharge elbow clogging, sandblasting pipe clogging, etc. Now I will analyze how to repair the problems and solutions.
Reasons for the blockage of the shotcrete machine rotor, discharge elbow or conveying pipe: 1. The aggregate particle size is too large 2. The moisture content of the dry mix is too large 3, the conveying air pressure is too low 4. The section of the air inlet pipe is too small and the air supply of the compressor is small
Solution for 1. The aggregate is too large: the feeding pipe is blocked, the machine should be stopped, the air valve should be closed, the feeding pipe should be removed from the elbow, the air valve should be opened, and the rotor material should be blown out. Then check the feeding pipe, tap the blockage with a wooden stick to loosen or hollow out the blockage (note: before disassembling the discharge elbow or pipeline, the pressure in the feeding pipe should be reduced to 0). The material pipe is then connected to the elbow and blown out with compressed air. If the conveying distance exceeds 40m, each 20m long pipeline should be treated separately.
For 2. The solution to the excessive moisture content of the dry-mixed material: stop the rotation of the machine and close the air valve. If the discharge elbow is blocked, the pipeline should be dismantled, and the elbow and rotor material cavity should be cleaned to reduce mixing. Mixture water-cement ratio.
The solution for 3. The conveying air pressure is too low: stop the motor and the air supply pipe. If the rotor is blocked, disassemble the air inlet pipe and the upper air pipe, and clean the rotor material cavity with a brush.
For 4. The section of the air inlet pipe is too small and the air supply volume of the compressor is small. The solution: replace the large section air pipe and replace the large-capacity compressor.
I believe that if you read this article carefully and carefully, you can fully grasp the judgment method and solution of shotcrete machine maintenance problems, and users can easily solve the small problems that occur during the use of these shotcrete support equipment.
