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 pressure was measured, together with move rate and head combos to pinpoint how successfully the pumps could meet the varying calls for of the system.
Included within the tyre manufacturer’s goals was the want to address pressure objectives for the system, which have been working at four.5 kg/cm2, compared to the contractual minimal supply strain of three.8 kg/cm2. Although the 5 pumps had the same casing, two of the impellers had been considerably different and Riventa found that by trimming the diameter of three pumps by 3.5%, an 11% discount in stress could be achieved.
By fully understanding the operation of the system and the way the pumps interacted with it, Riventa have been additionally capable of calculate optimum performance and make potential GPX suggestions.
At the start of the challenge, the GPX index, which signifies the amount of power as a proportion that’s successfully converted into helpful work by the drive, motor, pump and system, was 54, however after Riventa’s modifications, had improved to a GPX index of 64. So, of เกจวัดแรงดันpsi of electrical power consumed by the motor, just 54% of that power was being successfully transformed into web hydraulic output power.
