TEST STAND TO ANALYSE CENTRIFUGAL PUMP WORKING STAGE WEAR

摘要

FIELD: engines and pump. ^ SUBSTANCE: stand to analyse centrifugal pump working stage wear comprises motor drive 1, pump working stage chamber 2 that accommodates pump impeller 6 and abrasive material feed metering unit 7. Aforesaid element 6 represents variable-rigidity shaft 3. One end of shaft 3 is articulated, via coupling 4, with the shaft of motor 1. The other end of the said shaft that supports impeller 6 rests upon working stage guides vanes 5 via impeller hub 6. ^ EFFECT: higher validity of test results.
