1. Inspection before the concrete trailer pump works

Routine inspection, including the hydraulic oil level, whether there is water in the tank, the wear 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 is the inspection of lubricating oil quantity, which can lead to abnormal wear of large and small end 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.

2. Notes on the work of the concrete trailer pump

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, and it is best to mix the concrete every half an hour in between, 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, in case the rain enters the hopper when it rains, 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.

3. How to deal with the concrete pump machine after the blockage of the 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., 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.
