The concrete pump is designed to safely pump wet concrete through a delivery system of pipes and hoses within its published ratings and specifications. Stability of the concrete pump during operation is provided by the outriggers and front jack. Controls for the outriggers are located on the sides of the concrete …
This thesis studies the optimal design for a photovoltaic-powered medium-head (30 meters) water pumping system, with the emphasis on improving the efficiency and reducing the maintenance requirements of the electrical subsystem.
28 A Case Study: Design and Construction of Foundation and Braced Excavation at a Reclaimed Site at Waterfront The pumping station is located on reclaimed land and is just 11m from the harbour. The heterogenous nature of the dumped ﬁll forming the
A concrete pump is a machine used for transferring liquid concrete by pumping.There are two types of concrete pumps. The first type of concrete pump is attached to a truck or longer units are on semi-trailers. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately.

The Pumping System Design Process • Collect information • Determine type of pump to be used • Develop station layout • Develop system curves • Select pumps that match the system curves • Write your specification • Coordinate • Finalize the design 12
of truck-mounted concrete pump. Developed an optimal control strategy for booms of truck-mounted concrete pump and analyzed the characteristics of the hydraulic system also the joint angles, and then proposed the closed-loop detection and open
10/9/2016 · Excessive displacement of water by solids in fresh concrete mixture, after the compaction process is called Bleeding in Concrete. Concrete in fresh state is a suspension of solids ( aggregates and cement) in water, and after compaction there is a tendency for the solids to settle. This sedimentation displaces the water and water is pushed upwards.
concrete slab. soil pumping—vertical displacement and rebound of the soil support system in response to applied moving loads. water slump—magnitude of slump, measured in accor-dance with ASTM C143/C143M, which is directly attributed to the amount of
By far there is lack of research on different working conditions between rigid and flexible dynamics of truck mounted concrete pump booms. First a 3D model has been established by using virtual prototyping technology of a 37 m long boom in Pro/Engineering software. Then …

Basic Paralleled Pump Operating Point Figure 2 Figure 1 shows that each pump in a two pump parallel system with identical pumps is pumping one-half of the total design flow rate. If the pumps are identical, and are pumping the same flow rate, it follows that each
Design of reinforced concrete structures is governed by the nonlinear behavior of concrete and by its di erent strengths in tension and compression. The purpose of this article is to present a computational procedure for optimal conceptual design of reinforced
Reverse pumping links the concrete piston in the suction stroke and S-Tube valve to suck concrete from the s-tube instead of the hopper. As a result, the concrete piston pumps concrete into the hopper. The power for operation of the concrete pump is provided by the engine, which drives the hydraulic pumps. All functions for operation of the
To solve the problems of concrete piston striking cylinder and pumping insufficiency caused by the mismatch between varying loads and system's open-loop control property, the optimal model of concrete pumping displacement control was built.To be precise
1/1/2020 · Hence, the main contribution of this study is to propose an optimal design of the RFD for the seismic vibration control of an inelastic single–story steel moment–resisting frame (SMRF). For achieving this purpose, the parameters of the RFD subjected to an artificial earthquake were first optimized through minimizing the ratio of seismic input energy to dissipated the energy in the RFD.

This paper is focused on the optimal design of integrated sensor systems with both strain gauges and displacement transducers. Unlike traditional sensor placement approaches, in which these two types of sensors are often designed separately to monitor structural deformations and displacements respectively, the integrated design procedure presented in this study treats the sensor system as a …
