摘要：

The inherently slim design of the eccentric helical pump appears to make this type of PumP to be attractive for delivering water from deep wells, as compared with multistage centrifugal pumps. The basic shape of the volumeflow-head (V-H characteristics) of displacement pumps Promises a more economical use of the available solar energy than possible with centrifugal pumps. This article presents the results of experiments concerning the wear in eccentric helical pumps operating with water containing abrasive particles. The temporary stability of the fluid flow and of the efficiency during delivery of abrasive suspensions is demonstrated. The results are used to derive a prognosis for the expectable service life of such a pump system.
