Concrete pump in daily use, or to pay attention to some skills, good use habits can reduce the probability of failure of concrete pump, increase the life of concrete pump.

  1. Operators and equipment managers should read the instruction manual carefully to master its structural principles, use and maintenance and pumping of concrete-related knowledge, use and operation of concrete pumps, should be strictly in accordance with the instructions.

  2. The ground supporting the concrete pump should be flat and solid. The whole machine should be placed horizontally and should not be inclined in the process of working. The outrigger shall support the whole machine stably and be securely locked or secured. The location of the pump is not only convenient for the concrete mixer to feed into the hopper, but also beneficial to the pump distribution pipe and reduce the pump pressure loss Three concrete pump should be in accordance with the construction site characteristics and concrete pouring plan for pipe, pipe design to check whether the horizontal conversion distance of the pipeline and the pumping distance of the concrete pump. Piping should be as short as possible when the length of the pipeline, the use of bends and hoses. The laying of conveying pipe should be convenient for pipeline cleaning, trouble shooting, disassembly and maintenance. When the new pipe and the old pipe mix, should be placed in the new pipe pumping pressure greater.

  3. When the vertical pipe is needed for the concrete pump, there is a tendency of backflow in the concrete with the increase of height or potential energy, so a certain length of horizontal pipe should be laid between the concrete pump and the vertical pipe, to ensure that there is sufficient resistance to prevent the return of concrete. When pumping concrete for high-rise buildings, the vertical pipe should be arranged upwards, and the length of the horizontal pipe on the ground should not be less than 1/4 of the length of the vertical pipe. If the required length of the water pipe can not be placed due to site limitations, it can be replaced by a bend pipe or hose, and in the process of pumping concrete, with the increase of pumping pressure, pumping impact force will force the pipe to move back and forth, this is not only the loss of pumping pressure, but also the connection between the pump pipe in the state of impact and intermittent tension, can lead to premature damage to the pipe clamp and aprons, cement slurry overflow, so must be fixed; After the land concrete pump is connected with the conveying pipe, it should be checked according to the specification of the concrete pump. After running for 10 minutes without load, check if the mechanism or system is working properly, it is advisable to cover the concrete conveying pipe with wet straw bag, wet cover cloth and so on to avoid direct sunlight, which can prevent the pipe from clogging due to the rapid loss of concrete slump When concrete pumping construction is carried out in severe cold area in winter, proper heat preservation measures should be taken. It is advisable to wrap the concrete conveying pipe with heat preservation material to prevent the concrete in the pipe from freezing.
