Causes the concrete pump car to plug the tube to explode the situation to have those Concrete pump in the pump when there is a burst pipe and plugging the problem is also the most common, because this problem is also by the commercial concrete and the nature of the machinery itself to decide, Until now there is no way to fully guarantee that the concrete pump truck in the pump will not occur when the tube and plug the situation, can only be said to be in the pump when the most likely to avoid the occurrence of this situation.
That usually the most easily lead to the concrete pump tube explosion and plug the situation have those? 1, because of foreign bodies of materials and other foreign bodies of the blockage caused by the tube burst. In fact, the occurrence of this situation is mostly, the most often occurs is the foreign body because of the mixing of the blades, because sometimes the tanker transport if the number of concrete transported more times, will cause in the inside of the blade has broken or more serious wear, if At this time, the size of the broken blades is not particularly large, in case it is just able to pass through the hopper of the metal mesh and into the concrete pump truck in the hopper, then will be stuck in the conveyor cylinder and concrete pipe, as long as it is stuck, then inevitably there will be plugging the situation, It is also more difficult to check out the cause of the failure. If the blade is stuck in the position of the first arm tube, then the location of the pipe blockage may not be in the first arm, because the first arm of the pressure is very large, it is possible that the concrete will use this exit position of the high-pressure situation, will continue to flow downward, In the end, it will stay in the fourth and the third arm of the tube caused the blockage, but, in the maintenance staff will be the fourth arm pipe apart, you will find that the internal conditions are normal, but after the installation has not been a long time again appeared blocked.
So, in the presence of such a blockage of the situation, the first thing to consider is that in front of a certain part of the foreign body is stuck, the need to remove from the simple degree of difficulty, parts one by one of the demolition of the investigation. 2, the use of cement is high grade will be relatively easy to lead to the tube and plug the situation. The use of high grade cement configuration is easier on the occurrence of plugging, because concrete pump truck in the transport of concrete after a certain time, gradually will appear segregation and the situation of the initial coagulation, if in this key point directly to pump, then the situation of plugging pipe is also obvious,
The most serious will even cause the concrete pump car plug the situation, as long as there is a full line of blocking the situation, then need a large degree of disassembly and maintenance.
