A concrete pump truck is a device that integrates a pumping system for pumping concrete and a boom system for fabrics on a chassis of a vehicle. The pumping system uses the power of the chassis engine to pressurize the concrete in the hopper. Inside the pipe, the pipe is attached to the boom, and…
Pump manufacturers recommend between three to ten pipe diameters of undisturbed straight run upstream from pump inlets. Because process plants are designed to minimize plant floor space, it is not uncommon to find inadequate short runs of straight pipe upstream from pumps, control valves, check valves, flowmeters, and other critical process equipment. One of the most common flow disturbances found upstream from pumps in industrial process plants are 90°-degree elbows. Eliminating upstream piping requirements for pumps and irregularities associated with elbows can be accomplished by installing Taichan Company’s 90-Degree Elbow Flow Conditioner. This flow conditioner can be installed immediately upstream from pumps to ensure a swirl-free, repeatable and equally distributed flow profile. Flow Conditioning for Pump Protection Piping configurations that include 90-degree elbows introduce asymmetry and distortion resulting from accelerated flow near the outer wall of the bend. Although the cross-sectional area of an elbow may not change from section to section, separation will occur near the outer wall as the flow encounters the adverse pressure gradient that is developed in that region. Separation also occurs near the inside of the bend and downstream of the midsection due to adverse pressure gradients and sharp turn requirements. The combined separation reduces the area available to the core flow, causing the flow to be accelerated. Coriolis forces and the accelerated flow’s inertia through the bend produce a “dual eddy” swirl pattern with two counter-rotating vortices on either side of the center plane of the elbow. The vortices produce a strong traverse flow directed toward the outside of the elbow. The induced asymmetry may not only be extreme, but persistent In addition, some swirl is introduced into the flow as a radial velocity component. A single elbow close-coupled in a plane parallel to the shaft of a double suction pump generates distorted velocity profiles, vortices, and vapor pockets. The inertia of…
Other than capacity, the main difference between the various types of concrete pumps is determined by the additional equipment that comes as part of the pump. A concrete pump in its simplest form is best represented by a Stationary Concrete Pump. Additions to this, resulting in other types of concrete pump are: Transport – a dedicated vehicle…
Placing booms Placing booms support a 5-in.-diameter pipeline which re-ceives the discharge from a concrete pump and places it inthe forms. Booms have three or four articulating sections.The booms are mounted on a turret that rotates to enable the discharge of the pipeline to be located anywhere within a cir-cle. One type of boom telescopes 17 ft. Most booms are per-manently mounted to the trucks on which they are transported, along with the concrete pump. Some booms are designed to be…
Reliability, safety and efficiency are more important than ever for the pumping of ready-mixed concrete. Especially for deadline- bound projects, conveying pipes must not fail. Single-layer ST52 pipes will wear out within very short periods of time. This results in high costs for service providers in the ready-mixed concrete industry because of downtime due to repairs, service / maintenance work or the replacement of components. Taichan have developed and produced conveying pipes, elbows and special delivery line parts for truck-mounted concrete pumps, truck mixers concrete pumps or concrete distributing booms. The two-layer TWIN PIPES achieve a service life, which is significantly longer than ST52 pipes. Our pipes are checked for their pressure resistance at regular intervals. The hardness of TWIN PIPE pipes is constant over the entire pipe length so that service intervals can be scheduled more easily. All of our products are manufactured subject to the pump manu- facturers’ specifications. The special hardening process and high-quality welding process ensure that Taichan pipes achieve a service life, which is many times longer than that of commonly available ST52 pipes with the same…
Background to Concrete Pumps A concrete pump is a tool for conveying liquid concrete. Over a period of more than half a century, concrete pumps have slowly taken over from other methods of transferring liquid concrete. A number of different designs of concrete pump were developed in the first half of the 20th century…
Delivering the Concrete 4.1 WARNING! PLUGGING HAZARD. Do not put concrete into the concrete pump hopper, concrete pump truck hopper, and/or crane lift bucket until the operator directs you to do so. If the concrete pump or concrete pump truck has not been primed, filling the hopper can cause the concrete pump or concrete pump…
1. General WARNING! Concrete industry professionals should wear Personal Protective Equipment (PPE) when working near a concrete pump, concrete pump truck, or crane bucket. Proper equipment includes but is not limited to safety glasses, steel toe boots, hard hat, ear protection, and rubber gloves. These items are especially important when working near the hopper or…

concrete Pump pipe fittings, concrete pumping pipes are generally divided into two types, 125 and 150, and each of them has a high pressure and a low pressure. The low pressure type of the 125 type pump tube is a pipe with an outer diameter of Φ133, the high pressure is a pipe with an…
The pumping of concrete has become one of the fastest growing methods of trans- porting and handling at the job site. Pumping is a point-to- point delivery system in which con- crete is moved under pressure through rigid pipe, flexible hose or a combina- tion ofboth to its final destination in the forms with little ne- cessity for further handling of the mix. Hence, with pumping there is less chance for segregation. There are a number of other advantages in pumping concrete that should be con- sidered when evaluat-ing job site transport-ing and handling methods. The use of pumps can eliminate or greatly reduce the need for access roads, scaffolding, and other concrete handling equipment. Hoists and cranes are freed to handle other con- struction materials concurrently with concrete placing. Where tower cranes are being used the use of pumps permits them to be small-er and to speed…
