This contribution presents a novel wear dependent virtual flow rate sensor for single stage single lobe progressing cavity pumps. We study the wear-induced material loss of the pump components and the impact of this material loss on the volumetric efficiency. The results are combined with an established backflow model to implement a backflow calculation procedure that is adaptive to wear. We use a laboratory test setup with a highly abrasive fluid and operate a pump from new to worn condition to validate our approach. The obtained measurement data show that the presented virtual sensor is capable of calculating the flow rate of a pump being subject to wear during its regular operation.

“这里就是我心归属之地”,这是30年前我第一次踏进重庆大学校园时第一个闪过脑海的念头。在德国工作三年后,我决定去中国。那个早晨完美地始于街边摊上一碗辣辣的面条——重庆小面。1987年,北京的个体餐馆仍很少见,但是在重庆它们已经是街头不可或缺的风景了。重庆大学的校园更是无与伦比的美丽:亚热带植被、盛开的鲜花、上世纪20年代的历史建筑、校园中的湖泊和嘉陵江——重庆两大河流之一的峡谷,我还从未见过这样漂亮的校园。数小时后,当我离开重庆大学时,手里多了一份工作合同。这就是那个上午,那个似乎将改变我一生的上午。
