If the concrete pump valve jam how to judge and deal with？
After checking the blocked section, remove the pipe and use high-pressure air blowing or heavy hammer or high pressure water to wash it. After thoroughly cleaning, connect the pipeline to pump the concrete work.
The method of hammering with a wooden hammer can be combined with a positive and reverse pump to make it clear; when the above method is invalid, the obstruction is serious
When the pipe is blocked, the pump shall be taken repeatedly, reversing the pump, and gradually pump the concrete at the pump's outlet back to the hopper and mix again
After pumping concrete, be sure to use high-pressure water to pump the body and S pipe clean. When the rinse is not available, tap the tap to remove the residue until it is thoroughly clean.
The valve plug is formed gradually, the main reason is that after the completion of concrete pump, no time to use high-pressure water washing, resulting in concrete residue in the tube after a considerable period of time, gradually thickening, accumulation of consolidation, resulting in congestion.
