For a pressurised system that circulates cooling water for artificial rubber processing, Riventa utilised its FREEFLOW know-how and Green Pump Index (GPX) benchmarking system to concurrently monitor five pumps. For 150 hours, system stress was measured, together with circulate rate and head combinations to pinpoint how effectively the pumps could meet the various demands of the system.
Included within the tyre manufacturer’s aims was the necessity to handle pressure goals for the system, which had been working at four.5 kg/cm2, in comparison with the contractual minimum supply pressure of 3.8 kg/cm2. Although the five pumps had the identical casing, two of the impellers were significantly different and Riventa discovered that by trimming the diameter of three pumps by three.5%, an 11% reduction in pressure can be achieved.
By absolutely understanding the operation of the system and the way the pumps interacted with it, Riventa were additionally in a position to calculate optimum efficiency and make potential GPX recommendations.
At เกจวัดแรงดันออกซิเจนราคา of the project, the GPX index, which signifies the quantity of energy as a percentage that is successfully transformed into useful 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, simply 54% of that power was being successfully transformed into net hydraulic output power.
