　　隨著建筑行業的智能化程度越來越高，很多建筑機械已經代替了人工作業，大大的提高了工作效率，降低了人力成本的支出。混凝土輸送泵，又稱混凝土泵，由泵體和輸送管組成，是一種利用壓力將混凝土沿管道連續輸送的機械，主要應用于房建、橋梁及隧道施工。為了提高輸送泵的移動性，一般將泵體裝在汽車底盤上，再裝備可伸縮或屈折的布料桿，構成輸送泵車。目前，主要分為閘板閥混凝土輸送泵和S管閥混凝土輸送泵。
　　設備結構及基本性能
　　本項目以山東某設備產商WF型輸送泵車為例，其主要部件混凝土輸送泵由料斗、泵送系統、液壓系統、清洗系統、電氣系統、電動機、行走底盤等組成。
　　泵送機構由2只主缸水箱、換向裝置、2只混凝土缸、2只混凝土活料斗、分配閥(S形閥)、擺臂、2只擺動液壓缸和出料口組成。整機性能和液壓系統參數分別如表1、表2所示。
　工藝原理
　　混凝土活塞分別與主液壓缸活塞桿連接，在主液壓缸液壓油作用下，作往復運動，一缸前進，則另一缸后退;混凝土缸出口與料斗連通，分配閥一端接出料口，另一端能過花鍵軸與擺臂連接，在擺動液壓缸作用下，可以左右擺動。
　　泵送混凝土料時，在主液壓缸作用下，混凝土活塞可前進或后退。同時在擺動液壓缸作用下，分配閥與混凝土缸連通，混凝土缸與料斗連通。這樣混凝土活塞后退，便將料斗內的混凝土吸入混凝土缸，混凝土活塞前進，將混凝土缸內混凝土料送入分配閥泵出。
　　當混凝土活塞后退至行程終端時，觸發水箱中的換向裝置，主液壓缸換向，同時擺動油缸換向，使分配閥與混凝土缸連通，混凝土缸與料斗連通，這時活塞后退前進依次循環，從而實現連續泵送。
　　反泵時，通過反泵操作，使處在吸入行程的混凝土缸與分配閥連通，處在推送行程的混凝土缸與料斗連通，從而將管路中的混凝土抽回料斗。
　　泵送系統通過分配閥的轉換完成混凝土的吸入與排出動作，因此分配閥是混凝土泵中的關鍵部件，會直接影響到混凝土泵的性能。
　　方案選型
　　該設備所需的控制點數為數字量輸入12點，數字量輸出8點。其中主要的輸入輸出點為正泵、反泵、遠控/近控、主缸進/退、擺缸進/退、高壓 /低壓、電動機起動/停止、2個接近開關、4個電磁閥、指示燈運行指示。I/O點設置如表3所示。
　　由于該設備主要銷往海外市場，設備廠商在電控系統選型時主要考慮產品的高可靠性和品牌知名度。前者保證設備穩定運行，最大限度降低售后服務的成本，甚至無需售后服務;后者有助于提升設備整體的品牌，提升在海外市場的競爭力。
