There area unit many sorts of pump tubes, together with wear-resistant pump tubes, thick-wall pump tubes, thin-wall pump tubes, and wear-resistant pump tubes. several of them are within the class of machining, and lots of of them area unit stamping, forging, and roller process. , rolling technique, bulging technique, stretching technique, bending technique, and combined process technique.
Wear-resistant pump tube process is associate degree organic combination of machining and metal pressure process. The wear-resistant pump pipe is illustrated as follows: formation method: the top or a part of the pipe is punched out by a swaging machine to cut back the outer diameter. The common formation machine includes a rotary sort, a link sort and a roller sort.
Stamping: The tube ends area unit dilated to the desired size and form with a tapered core on the press. Roller method: The core is placed within the tube, and therefore the outer circumference is ironed by a roller for spherical edge process. Rolling method: usually, the spindle isn't used, and it's appropriate for the inner fringe of the thick-walled tube.
Bending forming method: There area unit 3 ways that area unit additional usually used. One technique is termed stretching technique, the opposite technique is termed stamping technique, and therefore the third one is that the roller technique that is acquainted to everybody. There area unit 3-4 rollers, 2 fastened rollers, one adjustment. Roller, modify the fastened roll distance, the finished pipe is bent. This technique is wide used, and if the spiral tube is created, the curvature may be hyperbolic.
Inflating method: one is to position rubber within the tube, and therefore the higher half is compressed by a punch to form the tube convexly formed; the opposite technique is hydraulic enlargement molding, filling the center of the tube with liquid, and therefore the liquid pressure drums the tube into a desired form.
The piping of the pump tube ought to be set in keeping with the principle of short distance and fewer elbow;
● The transport pipeline ought to be placed in associate degree accessible location for personnel to prepare and replace the transport pipeline;
● it's necessary to confirm that the joints area unit firm and stable, and a firm fixing purpose is more at the bend to stop the pipeline from being jolted and unsnarled throughout pumping;
● every tube card mustn't bit the bottom or the support surface, and may have an exact gap to facilitate dismantlement and assembly. At a similar time, all the pipe clamps should be in situ to confirm that the joints area unit tightly sealed, no suspension discharge, no air leakage;
● Horizontal pipe giving birth mustn't be suspended, and therefore the pump pipe should have sturdy support. once the transportation pipeline works for an extended time, it's necessary to own a wood support liner;
● At the outlet cone of the pump, it's not allowed to directly connect the elbow. a minimum of the straight pipe of over three meters ought to be connected, then the elbow ought to be connected;
●The transportation pipeline from three to five meters far from the pump ought to have instrumentation for fixing the transportation pipe to soak up the reaction force once the pumping concrete flows, in order that the pump is stable and therefore the oscillation of the concrete conveyancing pipeline is reduced; the concrete pump tube manufacturer
● The pipeline ought to be placed within the distance of the primary gushing, then secured to stop the pumping method from receiving, moving the operation;
●In summer, the pipeline is exposed to sturdy daylight. as a result of the concrete is hot, it causes dehydration and easily causes the pipe to be blocked. Therefore, the pipe is roofed with wet straw bag or alternative protecting merchandise. In winter, once the temperature is -5 °C, the transportation pipeline ought to be cowl the grass bag insulation to confirm the concrete mildew temperature;
● The transport pipe directly connected to the outlet cone of the pump should be fastened in order that every pumping is suspended, and therefore the pipe is straightforward to dismantle once cleansing the pipe;
