In the last piece, we learned some factors that can cause the blockage of concrete pump rubber hose. While this time let me introduce you how to prevent this problem.

Methods to prevent blockage problem of concrete pump rubber hose

First, before pumping concrete, pump some mortar to lubricate the concrete hose. Until the mortar is output from the end of the pipeline. Be sure to do this step well. You can use concrete pipe moisturizer instead of mortar. Because it is more convenient, fast and cheap.

Second, check if the concrete is qualified. Besides, check if there are large particle and segregation. While if you find any problems, deal with them in a timely manner.

Third, when you connect the delivery pump pipe, place a sealing rubber ring at the interface. Then use tools to tighten the pipe clamp. Then you can prevent the blockage caused by air leakage and slurry leakage.

Fourth, after the use, clean the concrete pump pipe in time. You can use a cleaning ball to clear the remaining concrete in the pump pipe. Then you can prevent concrete from solidifying in the pump pipe and causing pipe blockage.

Fifth, operators should pay attention to the pressure dial at all times. If they find a sudden increase in pressure, stop the pump immediately and perform a reverse pump operation. Repeat the operation three times to clear a small-scale pipe blockage.

Last, when using towed pumps or vehicle mounted pumps, you should use more straight pipes. Because if you use elbow hoses, the reinforce will be high inside the concrete pipe. Thus it will be easy to cause blockage.
