Tubing is machined metal pressure processing of organic combination made of. Tubing is an important part of the peristaltic pump, and the end user is often the wrong choice of pipe, causing it unsuitable for the desired applications. With the type of tubing on the market increased, but also the pump tube selection difficult. It has significantly improved the efficiency of the construction of the previously required by manual or crane buckets or practices changed a doo-fast delivery to require pouring concrete place, so that the construction efficiency by nearly a hundred times. Pump Pipe swaging machine will be part of the red end of the tube or extension, reducing the outer diameter, commonly swaging machine has a rotary, link type, roller. Stamping punch with a core that is tapered end of the tube to expand to the desired size and shape. Roller Method: Place the core in the tube, with the outer periphery of the roller pushing for a round edge processing. Rolling laws generally do mandrel adapted to the inside of the circular edge of thick-walled tube. Bending method: There are three methods more commonly used, a method called stretching method, another method called stamping method, and the third is more familiar roller method, 3-4 rollers and two fixed rollers, an adjustment roller, adjust the fixed roll away, finished pipe is curved. Wider application of this approach, if the production of spiral curvature can be increased only by understanding the concrete pump pipe in order to better use, concrete pump pipe has the following characteristics: (1) the pumping system constant power point: at home and abroad production of concrete pump, its pumping mechanism are constant power system, when pumping high pressure side at low pumping capacity, pumping pressure is low, the amount of increased power constant pumping parties, in favor of power and a main pump a reasonable match, can be seen from the pumping performance curve, from the transfer point hydraulic power curve is generally constant at around 15 ~ 18MPa. (2) Actual construction inevitable downtime and intermittent time: For a project should be translated to estimate the amount of conveyance, according to the pouring amount to be completed within the stipulated time to configure the device, it is quite sure. Therefore, the amount of the average pump concrete square at the operational time shall be 40% to 55% of the theoretical amount determined pumping party.
