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 5 pumps. For 150 hours, system stress was measured, along with circulate price and head combinations to pinpoint how successfully the pumps could meet the various demands of the system.
Included in the tyre manufacturer’s aims was the need to address stress goals for the system, which have been working at four.5 kg/cm2, in comparability with the contractual minimum supply pressure of 3.8 kg/cm2. Although the five pumps had the same casing, two of the impellers were significantly different and Riventa discovered that by trimming the diameter of three pumps by three.5%, an 11% discount in stress would be achieved.
By absolutely understanding the operation of the system and the way the pumps interacted with it, Riventa were also capable of calculate optimum efficiency and make potential GPX recommendations.
At the beginning of the venture, the GPX index, which indicates the amount of energy as a proportion 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 the one hundred pc of electrical power consumed by the motor, simply 54% of that power was being successfully converted into net hydraulic output energy.
