Concrete pump and pump pipe installation requirements

Concrete construction can not be separated from the concrete pump, a reasonable installation of concrete pump and pump tube can reduce the occurrence of failure to improve the efficiency of concrete transmission. Then the concrete pump and pump pipe installation requirements which, here we come to introduce.

  1 concrete pump must be arranged on the hard ground, there can not be obstacles around, easy access to concrete mixer.

  2 tubing turns at 90 ° elbow. Should be reserved from the floor through the hole, the level of the pump tube to use the horse stool to support the vertical pump tube at regular intervals to be fixed in the floor to use the hole with the use of cork and floor clamping, to prevent the pump tube full.

  3 pump pipe connection must use the standard tube card, the location of the card can not contact with the ground or support, tube card in the horizontal distance from the support ≥ 100mm, from the ground ≥ 100mm, pump pipe joints need to use the seal seal.

  4 When using a tower crane and other tools to pour an independent column, the floor, wall, roof beam of concrete using the pump pouring.

Concrete pump pipe English (Concrete pumppipe) referred to as concrete referred to as concrete (tóng), it is often referred to as concrete pump pipe. It is easy to understand that the pump tube is a new type of construction parts with the appearance of concrete pumps, and its appearance has greatly improved the efficiency of construction, the need to use artificial or crane a bucket or a Fighting the way to change the operation of the concrete to the need to pour the place, so that the construction efficiency increased nearly a hundred times.

Pumps are generally divided into 125 and 150 and 80 three, and these two have their own high pressure and low pressure of the points. 125 type pump tube low pressure model is the diameter of Φ133 pipe, high pressure for the diameter is Φ140 pipe; 150 type pump tube low pressure model is the diameter of Φ159 pipe, high pressure for the diameter is Φ168 pipe. The pipe head is a specially machined pipe joint, which is connected to the pipe body by welding. The connection of each pipe is connected by a pipe card which is processed by casting process.

Pump tube in accordance with the scope of use is divided into two types of car pump and pump tube, pump tube, including boom tube, hinge elbow, reducer and elbow, made of cast steel, straight pipe material 45mn2. To the pump tube for the ordinary 20 # carbon steel, by the fluid pipe or straight pipe, processed from.

Many types of pump tubing, including wear-resistant pump tubing, thick-walled pump tubing, thin-walled pump tubing, wear-resistant pump tube also belong to the category of mechanical processing, with the most punching method, forging method, roller processing Rolling method, bulging method, stretching method, bending method, and combination processing method. Wear-resistant pump tube processing is the organic combination of machining and metal pressure processing. Wear-resistant pump tube is illustrated as follows: Forging method: the use of forging the end of the tube or a part of the extension, so that the outer diameter reduction, commonly used forging machine has a rotary, connecting rod, roller type. Stamping method: Use a tapered core on the punch to extend the pipe end to the desired size and shape. Roller method: the tube placed in the tube, the outer wheel with a roller, for the round edge processing. Rolling method: generally do not have mandrel, suitable for thick-walled tube inside the round edge. Bending method: there are three methods are more commonly used, one method is called extension method, the other method is called stamping method, the third is more familiar with the roller method, there are 3-4 rollers, two fixed roller, an adjustment Roller, adjust the fixed roller distance, finished pipe is bent. This method is applied to a wider, if the production of spiral, the curvature can be increased. Bulging method: one is placed in the tube rubber, the top with a punch compression, the tube protruding shape; another method is the hydraulic bulging forming, filling the middle of the tube liquid, the liquid pressure to the drum drum into the required shape
