For a pressurised system that circulates cooling water for artificial rubber processing, Riventa utilised its FREEFLOW expertise and Green Pump Index (GPX) benchmarking system to simultaneously monitor 5 pumps. For one hundred fifty hours, system stress was measured, along with flow price and head combos to pinpoint how successfully the pumps might meet the various demands of the system.
Included in the tyre manufacturer’s goals was the need to handle stress objectives for the system, which had been operating at 4.5 kg/cm2, compared to the contractual minimum supply strain of three.eight kg/cm2. Although the 5 pumps had the same casing, two of the impellers have been considerably different and Riventa found that by trimming the diameter of three pumps by three.5%, an 11% discount in pressure can be achieved.
By totally understanding the operation of the system and the way the pumps interacted with it, Riventa have been also capable of calculate optimum performance and make potential GPX recommendations.
At the beginning of the venture, the GPX index, which indicates the quantity of energy as a share that is successfully converted into helpful work by the drive, motor, pump and system, was fifty four, however after Riventa’s modifications, had improved to a GPX index of sixty four. So, of the one hundred pc of electrical energy consumed by the motor, just 54% of that energy was being efficiently transformed into web hydraulic output power.
