How far can a concrete pump truck reach? this 6 factors determine the pumping distance, get it now

How far can a concrete pump truck reach? How much pressure? Are there requirements for the pump pipe? The most difficult thing about concrete pumps in the pumping process is the high concrete grade, small slump, high viscosity, long distance and high pumping pressure factors, which can lead to low pumping efficiency or insufficient pumping distance.

How to increase the pumping distance of concrete pump?

  1. using ready-mixed commercial concrete

The commercial concrete in pumping should usually use ready-mixed commercial concrete, and can also set up a commercial concrete station on site to supply pumping commercial concrete, it should be noted that hand-mixed commercial concrete cannot be pumped.

At the same time, the supplied commercial concrete should be strictly controlled in the pumping, and the change of slump should be noted at any time, and the commercial concrete which does not meet the requirements of pumping should not be allowed to enter the pump to ensure the effective work of the commercial concrete pump.

  1. Dedicated feeder

In the process of pumping commercial concrete, a separate screen should be set on the hopper of the commercial concrete pump, and at the same time, a person should monitor the feeding to avoid blocking the concrete pump due to the entry of too large diameter aggregate or foreign objects.

  1. Avoid pipeline vibration

In the pumping process, usually the stock of commercial concrete in the hopper should not be lower than the position of the mixing shaft, so as to avoid air entering the pump pipe causing pipe vibration.

  1. Pumping interruption time

If the pumping of commercial concrete needs to be interrupted, then generally the interruption time should not exceed 1 hour, and at the same time, reverse pumping and positive pumping should be carried out every 5-10 minutes to prevent the pipeline from being blocked due to water secretion or excessive slump loss of commercial concrete.

  1. Cleaning of hopper and conveying pipeline system

Usually, after the pumping of commercial concrete is finished, the hopper and conveying pipeline system must be cleaned carefully. If the residual commercial concrete cylinder is not cleaned, there will be the result of curing on the cylinder wall, and when the piston runs again, the piston sealing surface will directly bear the impact of the cured commercial concrete on the cylinder wall, which eventually leads to the local flaking of the pushing piston.

If this damage is different from the normal wear and tear of the piston seal, then the sealing surface will not be able to self-compensate under the action of pressure, which will eventually lead to slurry leakage or suction air condition, causing the powerless blockage of pumping, etc.

  1. Handling of pumping difficulties

If the pumpability of commercial concrete is poor or commercial concrete appears water, segregation and difficult to pumping conditions, then at this time should be immediately on the ratio, commercial concrete pump, piping and pumping process, etc., while taking appropriate measures to solve, and observe the pressure of the commercial concrete pump and the work of the system, after the normal work of the system in the normal speed of pumping.

How far can a concrete pump truck reach? How much pressure is there? Is there a requirement for the pump pipe? In fact, no matter how far the pumping, how much pressure, are very related to the product itself, and each kind of concrete pump will be equipped with a special pump pipe, not only can buffer the pressure and bearing capacity generated in the pumping.

What is the farthest pumping distance of a trailer pump?

There are many factors that determine the pumping distance of concrete trailer pump, first of all, the maximum pumping pressure of the equipment, the maximum pumping pressure directly determines the farthest pumping height and horizontal distance. The Zoomlion concrete pump mentioned above pumped C70 concrete to a height of 452 meters, the maximum pumping pressure of this pump is 48Mpa.

Secondly, the performance of the concrete will also affect its pumping distance. The same trailer pump, the concrete with low strength will pump farther than the concrete with high strength. This is because the different strengths of the concrete will cause the fluidity of the concrete to change. The better the fluidity, the smaller the pumping pressure required is naturally.

Therefore, all the time, the major brands are constantly challenging the limit of the farthest pumping distance. The farthest known human horizontal pumping distance is more than 2000 meters, however, the strength of pumped concrete is relatively low. Therefore, how far can the farthest pumping distance of concrete trailer pump? This is still an unknown.

The farthest concrete pumping distance directly determines how high your house can be built. In the future, as more and more super high-rise buildings, the existing pumping distance record may still be broken, looking forward to that day.

Trailer pump work in the notes

  1. Pre-work inspection

Routine inspection, including the hydraulic oil level, whether there is water in the tank, the wear and tear of wearing parts, the amount of lubricating oil and whether there is a blocked pipe and other parts of the inspection. If it is a motor pump, check whether the external voltage is normal, whether it is out of phase, whether the phase sequence of wiring is correct, etc.

It is easy to be neglected to check the amount of lubricating oil, which can lead to abnormal wear of the large and small ends and mixing wearing parts. At the same time, the external pump pipe line of the trailer pump should also be checked round, in case the pump pipe wears and leaks slurry, or the pump pipe card is not installed in place.

Therefore, there is a great risk to start construction as soon as you arrive at the site, and it is the safest way to start the machine after checking to.

  1. Precautions in work

Before pumping concrete, the drag pump also needs to pump a certain amount of mortar to lubricate the pump pipe. At the same time, according to the increase in the length of the connected pump pipe, the amount of mortar provided also needs to be increased accordingly to prevent the end of the pump pipe lubrication is not in place.

Before the mortar has been pumped, it should be lowered into the hopper to prevent the concrete concrete cylinder from sucking empty, which may lead to the occurrence of pipe blocking. At the same time, in the pumping process, waiting for the concrete to stop pumping should not be too long, in between it is best to mix the concrete every half hour forward and backward. In summer construction, the maximum interval should not exceed 1 hour.

The pump should be placed in a position that can block the rain to prevent the rain from entering the hopper when it rains and causing the concrete to segregate. During the working process, you should always pay attention to the pressure value of the pressure gauge of the trailer pump, to avoid holding the pump for a long time, or pumping pressure is not enough.

  1. How to deal with the blocked pipe?

Blocked pipe is one of the most common problems in daily life, first of all, after the blocked pipe should quickly find the location of the blocked pipe, unblock the pipeline, after completing the above work, but also do not rush to work immediately. You should find out the cause of the blocked pipe. If you don’t find out the cause, it is likely that the pipe will be blocked again, and the pipe just unblocked will be blocked again, which is not worth the loss.

Concrete segregation, concrete aggregate particle size is too large, pump pipe leakage, equipment failure resulting in insufficient pumping pressure, poor piston seal, poor sealing of the cobalt cutting ring, etc., all may lead to the problem of pipe blockage.

To sum up: every inspection and troubleshooting work is very important, do not ignore some problems you think is not a problem, these may become the hidden danger of equipment failure in the future. Operation, repair and maintenance should also be in accordance with the prescribed operating procedures, safe construction is the most important.

How to judge the distance that a concrete pump truck reach

Concrete pump truck reach the distance:

Concrete pump truck can reach the distance is related to the brand of the concrete pump truck. Concrete pump truck can reach the distance is also related to the size of the concrete pump truck. Pump concrete horizontal pumping distance can reach almost 300 meters, vertical conveying can reach about 100, much higher than the ordinary truck-mounted pump horizontal pumping 200 meters.
