Q:How can the concrete pump pipe be cleaned?
When the concrete in the pipeline has all been emptied and the sponge ball has been fired, the air washing is completed. At this time, the compressed air intake valve should be closed, and then remove all kinds of pipe fittings.
Q:In general, how much concrete will be transported per hour for the concrete pump and the pump?
The length of day pump 36-62m, the efficiency has little effect, regular work is generally 30-40 cubic / hour
Q:What do these types of concrete pumps mean?
HBT represents the ground pump (tow pump). 80 represents the theoretical throughput per hour, and 16 is the maximum outlet pressure of 16 MPa
Q:What is the second generation pumping technology of concrete pump?
The whole hydraulic control technology delivery pump has no constant pressure pump, no PLC in the control box, no nitrogen gas storage tank and no close switch at the water tank. The structure is simple, and the maintenance cost is greatly reduced.
Q:What is the difference between concrete pump and ground pump?
The pump is easy to move and flexible, but generally limited to the length of the boom by 60-70m. The ground pump is not limited by height, but it needs to be connected with the conveying pipe, which is of poor flexibility
Q:What are the layout requirements of concrete pump for building engineering?
Concrete pump or pump truck layout, parking site should have enough space, in order to ensure concrete mixing truck feeding, shunting convenience
Q:How is the piping of the concrete pipe designed?
When pumping underground structures, the horizontal axis of the ground shall be perpendicular to the axis of the Y - shaped discharge port
Q:How to deal with the blockage in the outlet of the distributing valve of the concrete pump?
If this method does not dare, it can only be manually removed, remove the connecting pipe, remove the debris in the valve.
Q:Why would the plugging concrete pump pipe
When pumping, the operator shall observe the leftover material in the hopper at any time. The remaining material shall not be lower than the stirring shaft. If there is too little material, the air will be easily inhaled, which will lead to pipe blockage. The material in the hopper can not be piled too much, should be lower than the guard bar, so as to clean up the coarse aggregate and super large aggregate in time
Q:What are the precautions for gas washing of concrete pump?
Compressed air pressure shall not be higher than 0.7MPa
