Reason fine aggregate concrete pump pipe blockageThe first one

Reason fine aggregate concrete pump pipe blockage The first one is to check whether the machine itself has a problem, the system pressure is mainly the fine aggregate concrete pump is normal, glasses, plates, whether there is a gap between the cutting ring, concrete mold vibrator price leaks link between the pipes, whether running when s pipe swing normally, start the machine, check the concrete cylinders, cylinder running is stable, normal, after completion of the above checks, did not find any problems, said details of stone concrete pump itself is not a problem, this time, it is generally considered a matter of fine stone concrete. Not all of the fine stone and concrete are pumped, only to reach fine concrete pump is suitable for pumping the required concrete pumping, pumping concrete with many factors, concrete aggregate size, slump, with the ratio factor, sand rate will directly affect pumping concrete, Fine aggregate concrete pump piping should follow to shorten the distance pipelines, reducing the principle of the elbow, because the longer the piping, the more the elbow, the greater the resistance of concrete in the pipeline, so the higher the chance of plugging, fine stone concrete Note should be pumped down the pipe so that there is a certain slope distance, circular saw machine steel bar cutting machine for sale not straight down, otherwise it is easy from the concrete sound of rain and cause plugging, concrete aggregate size should also choose the larger inner diameter of the thick concrete pump pipe This failure to generate also concerned with the transport arrangement of piping, horizontal pipe with respect to the length of the vertical pipe less than the end of the concrete pump and delivery tube with L type connector so prone to S tube blockage. S tube blockage treatment after the occurrence of the general operation of the pump can be eliminated with anti-clogging. Plugging portion judgment is correct or not, in the pipeline to open very easy to judge: as long as the pumping operation, apart from the nozzle have concrete outflow.     If the blockage site not far from the end of the pipe, clogging section after being fitted to clean up the back line, due to the effect of this airlock empty tube will clog again. In this case, it should be connected to the tube, pumped out and then take the next concrete pipe. Under normal circumstances, then the tube is not more than 10 meters. Every hose must concrete needle vibrator for sale price be connected to a concrete pumped out before continuing, otherwise it will also cause plugging. Remove the plugging manpower to organize as soon as possible, remove one of the concrete, and clean water
