Riventa pump system optimisation reduces power costs

In ราคาเพรสเชอร์เกจ of Yeosu in South Korea, pump optimisation specialist Riventa has created important savings at a worldwide tyre manufacturer’s water pumping plant, together with an annual power 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 5 pumps. For one hundred fifty hours, system strain was measured, together with circulate price and head combos to pinpoint how successfully the pumps may meet the varying calls for of the system.
Included in the tyre manufacturer’s aims was the want to tackle pressure aims for the system, which were working at four.5 kg/cm2, in comparability with the contractual minimal provide stress of three.8 kg/cm2. Although the 5 pumps had the same casing, two of the impellers were considerably different and Riventa discovered that by trimming the diameter of three pumps by 3.5%, an 11% reduction in stress can be achieved.
By totally understanding the operation of the system and how the pumps interacted with it, Riventa were additionally in a position to calculate optimum efficiency and make potential GPX recommendations.
At the beginning of the venture, the GPX index, which signifies the amount of energy as a share that’s 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 64. So, of the one hundred pc of electrical energy consumed by the motor, simply 54% of that energy was being efficiently transformed into net hydraulic output energy.
