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 concurrently monitor five pumps. For a hundred and fifty hours, system stress was measured, together with move price and head mixtures to pinpoint how effectively the pumps could meet the various calls for of the system.
Included within the tyre manufacturer’s aims was the necessity to address stress objectives for the system, which had been working at four.5 kg/cm2, in comparability with the contractual minimal provide pressure of 3.eight kg/cm2. Although the 5 pumps had the identical casing, two of the impellers were significantly totally different and Riventa discovered that by trimming the diameter of three pumps by three.5%, an 11% discount in strain would be achieved.
By fully understanding the operation of the system and the way the pumps interacted with it, Riventa had been additionally able to calculate optimum efficiency and make potential GPX recommendations.
At the beginning of the project, the GPX index, which indicates the amount of power as a percentage that is efficiently transformed into helpful work by the drive, motor, pump and system, was 54, however after Riventa’s modifications, had improved to a GPX index of sixty four. So, of the 100 percent of electrical energy consumed by the motor, simply 54% of that power was being efficiently converted into net hydraulic output energy.
