Résumé :
|
Erosion wear is a process that accompanies the facility for hydraulic transportation of solids. Since the pump is one of the vital parts of this facility, the working life of the pump is conditioned by the amount of wear. The working life can be realized only if the parameters chosen, for the pump elements, slurry, and transport conditions, will provide economic transport with minimal wear. Testing is the most reliable method for acquiring valid data. The two issues that need to be solved while planning the testing process are the choice of valid similarity criteria (test-industrial facility) and data selection. After the theoretical analyses, technically acceptable similarity criteria are obtained. A group of data needs to be defined through the experiment.
