Settlemen-texperimental method of diagnostics of de-gradation of some knots of centrifugal pumps

Abstract

In presented article the settlement-experimental method of diagnostics of degradation (deterioration) is offered. Some mobile details pumps. The offered method has a special urgency at work pumps under trying conditions, at movement of a liquid with mechanical impurity. The analysis of the considered. In article of examples of diagnostics of degradation of slot-hole consolidations, an epiploon and a surface of shovels pumps shows. That for each considered case monitoring and settlement rashodno-perepadnye and rashodno-tokovye characteristics have the characteristic form. Comparing external a kind of settlement and monitoring characteristics. It is possible to make the conclusion about presence or absence of deterioration of basic knots pumps, and also to define, what knot is exposed to intensive deterioration.
