基于PLC的液压混凝土输送泵电气控制系统设计
摘要
混凝土泵是通过专用管道依靠压力输送符合施工和泵送条件的混凝土到施工现场的建筑施工机械，它能一次连续地完成水平输送和垂直输送，具有高效的工作效率和方便的移动功能。本文在深入地分析和研究混凝土泵控制系统的功能和要求后，采用PLC对混凝土输送泵电气控制系统进行设计，控制三台异步电动机分别实现混凝土输送泵的主油泵电机和风冷电机启停控制以及系统的润滑工作；通过控制其液压系统中的电磁换向阀的通断，实现使液压系统驱动泵的正泵、反泵运行；主油缸前进、后退控制及点动等控制。在实现近程、远程控制的同时，并对控制系统实现了一种S管的摆动和主油缸的动作实行“步步到位”的新型控制模式。实践证明，基于PLC的混凝土输送泵电气控制系统提高了系统工作效率，具有良好的工程应用价值。

Design of Electrical Control System For Hydraulic Crete Delivery Pump Based on PLC
ABSTRACT
The concrete pump is a building construction machinery through a dedicated pipeline to transmission concrete meet the construction and pumping conditions to the construction site rely on pressure, it can transport the concrete with horizontal and vertical continuously, with high efficiency and convenient mobility features. This paper under detailed analysis and research of functions and requirements of the concrete pump control system, use PLC to design the concrete pump electrical control system, control three asynchronous motor to respectively realize on off control of the oil pump motor and air-cooled motor of concrete pump and the lubrication of system; By controlling the electromagnetic valve on-off of hydraulic system, realize to making the drive pump of hydraulic system positive pump and negative pump run; forward control and back control of the master cylinder, and jog and other controls. While short-range and remote controlling, realize a new control mode to the control system that an S pipe swing and master cylinder moves to implement step by step in place. It is proved that the design of hydraulic concrete pump electrical control system based on PLC improve the efficiency of the system, it has a good value of engineering applications.
