Quantitative air entrapment fault test device

The invention discloses a quantitative air entrapment fault test device. In the field of liquid delivery, an air entrapment fault is an inevitable fault, the liquid delivery quality is directly influenced by the air entrapment amount and position of the air entrapment fault, particularly, air entrapment caused by long-term air leakage has direct influence on the liquid quality, and corresponding quantitative air entrapment research needs to be developed. The device can effectively simulate the air entrainment condition, can add targeted gas into the conveyed liquid according to the demand quantity, and studies the states of the conveyed liquid under different air entrainment quantity conditions, so that the air entrainment condition in the actual work of liquid conveying is diagnosed, and corresponding measures can be taken. 本发明公开了一种量化夹气故障试验装置。在液体输送领域中，夹气故障是一种必然存在的故障，其夹气量的大小和位置直接影响液体输送的质量，特别是长期的漏气带来的夹气对液体品质有直接影响，需要开展相应量化夹气的研究。本装置可有效模拟夹气情况，能够按照需求量在输送液体中加入针对性气体，研究输送液体在不同夹气量情况下的状态，从而为液体输送实际工作中的夹气情况进行诊断，并可采取相应措施。
