一种实验室压力模拟装置

Abstract

本公开涉及实验室用工具技术领域，本公开的一个实施例提供了一种实验室压力模拟装置，其包括：集成板，集成板上设置有循环风机，连通管与循环管之间相连通。通过上述技术方案，解决了现有技术中传统装置仅能实现简单的压力调节，难以精准模拟复杂多变的压力环境，像一些早期的水压模拟试验装置，在试验件体积短时间内迅速变化时，由于水的压缩性极小，装置内压力会急剧上升，既无法满足试验件动作过程中水压恒定或按规定压力变化的要求，还可能对试验系统造成危险，还有一些压力模拟设备，其结构复杂、成本高昂，如利用国外高转速离心机进行特殊流体挤出测试，单次测试成本巨大，限制了相关研究的广泛开展的技术问题。
