Technical details and manufacturing context for Delivery System

Definition
The delivery system in a truck-mounted concrete pump is the core component that transfers mixed concrete from the hopper through the boom's articulated pipeline to the precise placement location. It consists of hydraulic cylinders, pumping pistons, valves, and pipeline sections that work together to maintain continuous concrete flow under pressure. The system is designed for high-strength alloy steel and wear-resistant hardened steel components, with specialized rubber seals to ensure durability and leak-free operation. Key parameters include a delivery capacity of 15–60 m³/h, a maximum delivery pressure of 8–16 MPa, and a hydraulic system pressure of 25–35 MPa. The pipeline diameter ranges from 125–150 mm, and the delivery cylinder stroke and diameter are 1400–2100 mm and 180–230 mm, respectively. Operating temperature ranges from -20°C to 60°C, and hydraulic oil viscosity should be 46–68 cSt at 40°C per ISO 3448. Seal materials are NBR–PU, and the system weight is 800–1500 kg. These values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The delivery system is a critical component that affects the pump's performance, reliability, and safety. Proper selection and maintenance are essential to ensure efficient operation and prevent failures. Regular inspection of seals, pistons, and valves is recommended to detect wear and avoid downtime. The system's design allows for continuous concrete flow, minimizing pressure fluctuations and ensuring consistent placement. Understanding the working principle and maintenance requirements is crucial for operators and maintenance personnel. This directory entry provides a neutral overview of the delivery system's function and specifications, without endorsing any particular brand or manufacturer.
Working Principle
Hydraulic cylinders drive reciprocating pistons that create suction to draw concrete from the hopper into the pumping chamber, then apply pressure to force it through the delivery pipeline. S-valves or gate valves alternate flow direction to maintain continuous output while preventing backflow. The system operates within a hydraulic pressure range of 25–35 MPa, and the delivery pressure is controlled to stay within 8–16 MPa to avoid pipeline damage. The reciprocating action is synchronized with valve timing to ensure smooth flow and minimize pulsation. The delivery cylinder stroke and diameter determine the volume per stroke and the force applied, affecting the overall capacity and pressure. The system is designed to handle concrete with appropriate viscosity and aggregate size, and the pipeline diameter is selected to balance flow rate and pressure loss. Proper hydraulic oil viscosity and operating temperature are critical for efficient operation and component longevity.
