METHOD OF DETECTING OCCLUSIONS IN A SOLUTION PUMPING SYSTEM |
摘要 |
A method of detecting occlusions in a solution pumping system includes monitoring and analyzing pressures within the system during selected portions of a pumping cycle. The pumping system of the illustrated embodiment includes a positive displacement pump operated by a reciprocable pump piston, with analysis of pressures within the system identifying those conditions which reflect the presence of an occlusion either upstream or downstream of the positive displacement pump. A suitable signal or alarm can then be activated to alert operating personnel.
