Tips

(1) operators and related equipment management personnel should read the instruction manual and grasp the structural principle, use and maintenance of the knowledge and pumping concrete; the use and operation of concrete pump, should be strictly in accordance with the instructions executed. Because the operator can fully grasp the mechanical properties of the need to have a process, it should be randomly alternate instruction manual. 90m3 ready mixed concrete batching plant At the same time, should develop specific action points based on manual, to achieve effective control of pumping technology in some variables, such as the pump position, piping, etc. (2) supporting concrete pumps ground should be flat, solid; machine required horizontal, not inclined during operation. Legs should be stably support machine, and securely locked or fixed. Position both easy to pump concrete mixer truck in and out of the hopper and feed, but also beneficial to consider pumping and piping to reduce the pumping pressure loss, and to ask from the pouring location near convenient power and water supply. (3) should be carried out according to the construction site characteristics pipes and concrete placement scheme, piping design to the level of checking whether the pipeline in terms of distance from the concrete pumps and pumping adapt. Piping should be as short as possible length of the pipeline, less elbow and hose. Delivery pipe laying pipelines should be easy to clean, troubleshooting, and disassembly and maintenance. When the new pipes and old pipe mix, should the new pipe installation in pumping pressure at large. Piping process should draw piping diagrams, lists a variety of pipe fittings, pipe card, elbow and hose size and number, and provide a list. (4) the need to perpendicular to the pipe, as the height increases an increase of potential energy, there is upward trend reflux concrete, and therefore should be laid horizontal pipe length between the concrete pump and vertical piping, in order to ensure 2015 dasion js750 concrete mixer specifications there is enough concrete to prevent resistance reflux. When pumping concrete high-rise buildings require vertical pipe up, at which time the ground level pipe length less than 1/4 the length of the vertical tube. When as a result of space limitations, can not be placed above the desired length of water pipe, can be bent pipe or hose instead. (5) in the concrete pumping, pumping with pressure increases, pumping the impact will force the tube back and forth, not only the loss of the pumping pressure, but the pump pipe joints in between shocks and discontinuities state by pulling can lead to premature failure of control card and apron, slurry overflow, and therefore must be fixed to the pump. (6) concrete pump in communication with the delivery tube, the pump should be concrete instructions for the full inspection, in order to meet the requirements after the boot empty running. After the load operation 10min, and then check the bodies or systems are working properly. (7) When construction of the hot season, it is appropriate wet straw bags, drop cloths and other objects covered with wet concrete delivery pipe to avoid direct sunlight to prevent the collapse of the concrete due to the rapid fall of the loss caused by blocked tubes. (8) in the winter cold areas of concrete pumping hls120 concrete batching plant manufacturer construction, should take appropriate insulation measures, it is appropriate insulation material encased concrete pipes, cold concrete to prevent the inner tube.
