PUTZMEISTER/JUNJIN concrete boom pump:

The main principle of the pumping pipeline is to use the high-strength ceramic material to protect the inner wall of the pipeline, and the dynamic mechanical principle is used to optimize the pipeline to minimize the wear of the pipeline.

Pump truck pipeline operating specifications:

1. After replacing the new pipe, in order to avoid blocking the pipe, the pressure can be appropriately increased by 2-3MPa. After the 3000-4000 cubic meter is delivered, the pressure will be restored to normal.

2. When conveying gravel concrete, do not fill the top 3000 squares, so that the material in the pipe does not exceed 40%.

3. During the waiting period, the air pump should be used several times to avoid blocking the pipe.

4. After the operation is completed, all the concrete in the pipeline should be output, and then the pipeline should be washed. It is strictly forbidden to wash the pipe with a sponge ball to avoid blockage.

5. When the pipeline is clogged, it is not advisable to strike the pipeline with force. The reverse operation method can be used to eliminate the pipeline blockage. When it is invalid, the pipe should be cleaned.

6. If conditions permit, it is recommended to connect the entire set of pipes to another pump truck to clear them. If the conditions are not available, remove the first arm 90 degree elbow, tap the 3m straight pipe, and take out the blocked concrete.

There are many types of pump tubes, including wear-resistant pump tubes, thick-wall pump tubes, thin-wall pump tubes, and wear-resistant pump tubes. Many of them are also in the category of machining, and many of them are stamping, forging, and roller processing. , rolling method, bulging method, stretching method, bending method, and combined processing method.

Wear-resistant pump tube processing is an organic combination of machining and metal pressure processing. The wear-resistant pump pipe is illustrated as follows: Forging method. The end or part of the pipe is punched out by a swaging machine to reduce the outer diameter. The common forging machine has a rotary type, a link type and a roller type.

Stamping: The tube ends are expanded to the required size and shape with a tapered core on the press. Roller method: The core is placed in the tube, and the outer circumference is pressed by a roller for round edge processing. The rolling method generally does not use a mandrel, and it is suitable for the inner edge of the thick-walled tube.

Bending forming method: There are three methods that are more commonly used. One method is called stretching method, the other method is called stamping method, and the third one is the roller method which is familiar to everyone. There are 3-4 rollers, two fixed rollers, one adjustment. Roller, adjust the fixed roll distance, the finished pipe is bent. This method is widely used, and if the spiral tube is produced, the curvature can be increased.

Inflating method: One is to place rubber in the tube, and the upper part is compressed by a punch to make the tube convexly formed, the other method is hydraulic expansion molding, filling the middle of the tube with liquid, and the liquid pressure drums the tube into a desired shape.

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.
