Shotcrete Machine Should Be Overcome Some Problems In Normal Operation

There will be some shotcrete machine rotor blockage, discharging elbow blockage, sandblasting pipe clogging phenomenon in the actual operation, to analyze the causes of these problems and solutions. Shotcrete machine rotor, material elbow or conveying pipe blocking reasons: aggregate size; dry mixture containing water; conveying air pressure is too low; the air inlet pipe section is too small, the pressure fan for air volume is small. 1, The aggregate is too large solution: the pipe blockage, should stop the machine rotation, turn off the gas valve, remove the pipe from the elbow, open the gas valve, the rotor of the stored material blow out. Then check the transportation pipe material, with a wooden stick, knocking the blocked parts, vibration loose or emptied blockage (Note: in apart from material elbow or the pipeline before to the material conveying pipe pressure drop to 0) finally, the conveying pipe is connected to the elbow, compressed air is blown out, if the transmission distance of more than 40m, every 20m long pipeline respectively. 2, Dry mix moisture way to solve the large: the machine stops rotating, air valve is closed, if the discharging elbow plug should be open the pipeline for, cleaning elbow and rotor material cavity, reduce mix water cement ratio. 3, The transmission of air pressure is too low solution: to stop the motor and supply air lines, if the rotor is blocked, should be open into the wind pipe and the upper hand, with a brush to clean up the rotor cavity, etc.. 4, Into the wind pipe section is too small, the pressure fan for small wind flow solutions: the replacement of large section of the wind pipe, the large capacity of the wind pressure.
