采用自行设计的活塞式液体灌装试验系统,利用正交试验方法,考察了灌装速度、液位跟踪距离、喷嘴内径和喷嘴出液口形状对灌装过程中滴漏和起泡现象的影响,确定了该活塞式液体灌装系统的最佳灌装参数。通过试验,确定了影响滴漏现象的主要因素为低速段速度和出液口形状,影响系统起泡现象的主要因素为喷嘴内径和液位跟踪距离,可以为活塞式液体灌装系统设计研发以及调试过程中的参数选择提供一定的指导。

The effect of filling speed, tracking range of liquid level, nozzle diameter and the shape of nozzle ondripping and foaming during filling process was studied using orthogonal test method. The best operation parameters of the liquid filling system were determined. The result showed that the main influencing factors on drip phenomenon are speed in low speed period and shape of the nozzle; the main influencing factors on foaming phenomenon is nozzle diameter and tracking range of liquid level. The purpose was to provide gaidance for piston liquid filling system design and parameters selection.
