What are the reasons for the blockage of concrete pump trucks?

When the concrete pump truck has blocked the pipe, it is necessary to carefully analyze the concrete pump truck to the blocked pipe from the aspects of pump wear, pipe connection, external environment, and local pump pipe leakage. the reason. Then in the daily operation, it is necessary to obey the correct operating rules to reduce the risk of blockage.  

1. Plugging due to improper pipe connection of the concrete pump truck : The horizontal distance of the pipe connection of the pump truck should be shortened. This can reduce the arrangement of the maximum elbows and elbows so that the concrete resistance will be effective. The reduction in the number of pipe plugs has also been reduced. If the height of the pipeline is too high, the pump truck should be installed with a separate isolation device to prevent pipe plugging. When the pump truck is pumping at a high level, a stop valve should be installed at the junction of the vertical pipe and the horizontal pipe to prevent the pipe plugging.  

2. Plugging caused by improper operation of the operator: When the concrete pump truck is pumping, the pumping speed is too fast and too slow. When the pipeline is in excess of resistance, it will Caused a blockage. When the pumping starts, the speed should be slowed down. Once the pumping is normal, the pumping speed can be increased. Because the pump pipe that was pumped last time did not do a clean-up work, this caused the blockage caused by the excessive resistance of the concrete. When the concrete pump truck is feeding, because of improper control, it leads to blockage of the pipe. Therefore, when pumping, the operator should observe the concrete in the hopper anytime and anywhere, and should not be too much or suitable. too little. If the amount is too small, the pump will cause a blockage due to inhalation of too much air.  

3, because of the concrete pipe pump pump wear caused by blocking the pipe. The operator should regularly observe whether there is turbidity in the water in the water tank of the pump. If there is mortar in the water or it has been muddy, then the piston has been worn out. This will reduce its The pressure value will easily cause a blockage.
