For a pressurised system that circulates cooling water for synthetic rubber processing, Riventa utilised its FREEFLOW expertise and Green Pump Index (GPX) benchmarking system to simultaneously monitor five pumps. For 150 hours, system pressure was measured, together with circulate price and head mixtures to pinpoint how effectively the pumps may meet the various demands of the system.
Included in the tyre manufacturer’s aims was the necessity to address pressure aims for the system, which had been operating at four.5 kg/cm2, in comparison with the contractual minimum supply stress of three.eight kg/cm2. Although the five pumps had the identical casing, two of the impellers had been considerably different and Riventa discovered that by trimming the diameter of three pumps by 3.5%, an 11% discount in stress can be achieved.
By absolutely understanding the operation of the system and how the pumps interacted with it, Riventa were additionally capable of calculate optimum efficiency and make potential GPX recommendations.
At pressure gauge 0 10 bar ราคา of the project, the GPX index, which indicates the quantity of energy as a percentage that is successfully transformed into useful 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 100% of electrical power consumed by the motor, simply 54% of that energy was being efficiently transformed into web hydraulic output power.
