I plant specializing in the production of concrete pump pipe, wear-resistant pipe products, concrete pump tubing should be based on the model of pump, mixing material properties, the total output, unit output, transmission distance, and aggregate size, etc. selection; when concrete coarse aggregate maximum particle size of not more than 25mm, can not be less than the inner diameter of the pump tube 125mm; when concrete coarse aggregate maximum particle size of not more than 40mm, can not be less than the inner diameter of 150mm tube pump; concrete pump pump tubing should bracket, the bracket should be firmly connected to the structure, the steering pump tube at the stand should be encrypted. Stand should be determined by calculation, if necessary, set the position to deal with checking the structure; concrete pump tube is short, because concrete short concrete (tóng), so often referred to as a concrete pump. It is easy to understand, with the emergence of concrete pump tube concrete pump while the emergence of a new type of building engineering accessories, it has significantly improved the efficiency of the construction of the previously required by manual or crane buckets or Doudou operating mode to a fast delivery to require pouring concrete place, so that the construction efficiency by nearly a hundred times. ? Wear pump pipe wall through a special treatment, with a certain compressive strength and abrasion resistance; abrasion resistance tubing belongs among the concrete mechanical wearing parts, because in the process of delivery of concrete which concrete will wear the pump tube to wall caused great pressure (there are about a dozen ordinary concrete pumps MPa), plus the concrete pump pipe friction and wear, abrasion resistant tubing wall becomes thinner, until finally damaged and need a new one wear tubing to much-needed work. So be sure to pay attention to wear tubing procurement and maintenance.
