Riventa pump system optimisation reduces energy prices

In the port metropolis of Yeosu in South Korea, pump optimisation specialist Riventa has created important savings at a global tyre manufacturer’s water pumping plant, including an annual energy discount 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 fee and head combinations to pinpoint how successfully the pumps could meet the various calls for of the system.
Included within the tyre manufacturer’s goals was the want to address strain objectives for the system, which had been operating at 4.5 kg/cm2, in comparison with the contractual minimum supply strain of three.8 kg/cm2. Although the 5 pumps had the same casing, two of the impellers had been considerably completely different and Riventa discovered that by trimming the diameter of three pumps by 3.5%, an 11% discount in strain can 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 suggestions.
At เพรสเชอร์เกจ4นิ้ว of the project, the GPX index, which indicates the quantity of energy as a percentage that is efficiently 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 sixty four. So, of the one hundred pc of electrical energy consumed by the motor, just 54% of that energy was being efficiently converted into internet hydraulic output power.
