Riventa pump system optimisation reduces energy prices

In the port city of Yeosu in South Korea, pump optimisation specialist Riventa has created vital savings at a global tyre manufacturer’s water pumping plant, together with an annual power reduction of 13%.

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 a hundred and fifty hours, system strain was measured, along with circulate rate and head mixtures to pinpoint how successfully the pumps may meet the varying calls for of the system.
Included within the tyre manufacturer’s objectives was the want to handle stress aims for the system, which had been working at 4.5 kg/cm2, in comparability with the contractual minimal provide pressure of 3.eight kg/cm2. Although Black market had the identical casing, two of the impellers have been significantly different and Riventa discovered that by trimming the diameter of three pumps by 3.5%, an 11% discount in pressure can be achieved.
By fully understanding the operation of the system and how the pumps interacted with it, Riventa were additionally able to calculate optimum efficiency and make potential GPX recommendations.
At the start of the venture, the GPX index, which indicates the amount of power as a share that’s 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 64. So, of Recognized of electrical power consumed by the motor, just 54% of that energy was being successfully transformed into web hydraulic output energy.
