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 a hundred and fifty hours, system stress was measured, along with flow price and head combinations to pinpoint how effectively the pumps could meet the various demands of the system.
Included within the tyre manufacturer’s goals was the want to handle stress goals for the system, which were working at 4.5 kg/cm2, compared to the contractual minimum supply pressure of three.eight kg/cm2. Although the five pumps had the identical casing, two of the impellers have been significantly different and Riventa discovered that by trimming the diameter of three pumps by three.5%, an 11% reduction in strain would be achieved.
By fully understanding the operation of the system and how the pumps interacted with it, Riventa were additionally in a position to calculate optimum performance and make potential GPX suggestions.
At the start of the project, the GPX index, which indicates the quantity of power as a percentage that’s successfully converted into helpful work by the drive, motor, pump and system, was fifty four, but after Riventa’s modifications, had improved to a GPX index of 64. So, of the 100% of electrical power consumed by the motor, simply 54% of that energy was being efficiently converted into net hydraulic output energy.
