For a pressurised system that circulates cooling water for synthetic rubber processing, Riventa utilised its FREEFLOW know-how and Green Pump Index (GPX) benchmarking system to concurrently monitor five pumps. For 150 hours, system pressure was measured, together with flow price and head mixtures to pinpoint how effectively the pumps might meet the varying calls for of the system.
Included in the tyre manufacturer’s objectives was the necessity to handle pressure objectives for the system, which had been working at four.5 kg/cm2, in comparability with the contractual minimum provide stress of 3.8 kg/cm2. Although the 5 pumps had the identical casing, two of the impellers were considerably completely different and Riventa found that by trimming the diameter of three pumps by 3.5%, an 11% discount in strain would be achieved.
By absolutely understanding the operation of the system and how the pumps interacted with it, Riventa had been additionally capable of calculate optimum performance and make potential GPX recommendations.
At Save of the venture, the GPX index, which indicates the quantity of energy as a percentage that is efficiently transformed 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 Downloadable of electrical power consumed by the motor, simply 54% of that energy was being efficiently converted into net hydraulic output power.
