Description

一种智能操控水试验平台 技术领域
本发明涉及一种试验平台，尤其涉及一种针对分布器的智能操控水试验平台。
背景技术
填料塔中需要用液体分布器来分布进料液体，为了更好的发挥填料的性能，往往需要配以高性能的液体分布器等塔内构件。而衡量液体分布器性能高低的主要标准就是其分布液体的均匀性。
工业生产制造出来液体分布器在出厂前应进行液体分布均匀性的检测试验，但目前此类检测平台较少，而且检测平台可检测的流量变化范围较小，自动化程度较低。因此，工业实际中有必要设计一个可测流量变化范围较大并且自动化程度较高的液体流量测量系统及测量方法。
发明内容
发明目的：针对背景技术中的缺陷，现提供一种智能操控水试验平台，通过对液体分布器不同区域的流量数据进行测量、记录处理，可方便准确地检测液体分布器分布液体均匀性，为评判液体分布器性能提供可靠依据，结合机械臂实现分布器的自动上下料拆装，通过主控平台实现整体的智能化控制。
技术方案：本发明所揭示的一种智能操控水试验平台，包括试验水池，安装在试验水池内的纵向支撑架，搁置在纵向支撑架上的横向支撑梁，安装在试验水池一侧边的变频水泵，该变频水泵上端连接有水管延伸至试验水池上方，所述试验水池两个对角上安装有四轴联动机械臂，实现待试验分布器的自动拆装，还包括主控台，显示屏及PLC控制器安装在试验水池外围地面上，通过主控台发送控制指令给PLC控制器，从而实现对四轴联动机械臂以及变频水泵的操控， 所述显示屏与主控台连接，显示水试验平台运行的各项参数。
作为优选，所述水管包括L型送水管及喷水管，送水管的一端连接变频水泵，另一端与喷水管中心位置连通，且喷水管与送水管垂直设置，所述喷水管下端面具有多个间隔设置的喷头。
作为优选，所述横向支撑梁侧面间隔安装有多个接收盒，用于收集分布器流下的液体，且接收盒底部的流出管上安装有液体流量计连接主控台，统计该局部位置的流量值，并由主控台进行分析。
作为优选，所述主控平台连接有线网络，实现试验数据的网络传输至云平台。
作为优选，所述纵向支撑架包括多根纵向梁以及安装在两根纵向梁之间的多个加强横轴。
有益效果：本发明所揭示的一种智能操控水试验平台，具有如下有益效果：
通过变频水泵可以根据控制要求自动调节送入水流量大小，同时通过分布在底部横向支撑梁上的收集盒进行局部流量统计，从而可以了解分布器不同区域的流量值，并回传给主控台进行记录分析，从而准确的检测分布器液体分布的均匀性，为分布器性能的评判提供可靠依据；
采用两个对向设置的机械臂可以实现分布器自动安装和自动拆卸，免除了人工拆装的繁琐性，极大的提高了测试效率；
采用主控台对整个水试验平台进行自动化控制及数据采集，通过显示屏进行全面显示实时掌控各部位的工作情况，还可以利用网络将试验数据上传云平台，整个平台自动化程度高，测量精度高，可以实现多点精确测量，提高了试验效率。
