Riventa pump system optimisation reduces vitality prices

In the port city of Yeosu in South Korea, pump optimisation specialist Riventa has created significant savings at a global tyre manufacturer’s water pumping plant, including an annual energy 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 stress was measured, together with flow fee and head mixtures to pinpoint how effectively the pumps could meet the various calls for of the system.
Included within the tyre manufacturer’s aims was the want to address stress objectives for the system, which were operating at four.5 kg/cm2, in comparability with the contractual minimum provide strain of 3.eight kg/cm2. Although the five pumps had the same casing, two of the impellers were considerably totally different and Riventa found that by trimming the diameter of three pumps by three.5%, an 11% reduction in pressure would be achieved.
By absolutely understanding ไดอะแฟรม of the system and the way the pumps interacted with it, Riventa have been additionally capable of calculate optimum efficiency and make potential GPX recommendations.
At the beginning of the project, the GPX index, which signifies the quantity of energy as a proportion that is successfully converted into helpful work by the drive, motor, pump and system, was fifty four, but after Riventa’s modifications, had improved to a GPX index of 64. So, of the 100 percent of electrical energy consumed by the motor, just 54% of that power was being efficiently transformed into net hydraulic output power.
