"Pump, fan testing key technology research" subject acceptance

Recently, the “Eleventh Five-Year” National Science and Technology Support Program “Key Technologies for Key Technologies for Energy Saving of Industrial Motors and Typical Pump Valves” key projects of the “Eleventh Five-Year” National Science and Technology Products Testing Institute and other units were jointly undertaken in Hefei, Anhui Province. acceptance.

The project carried out studies on inflow characteristics testing, tracer particle follow-up testing, inflow induced noise testing, vibration and pressure pulsation testing, new diffuser and tip clearance tests, and established a rotating turbulent flow field in a centrifugal pump. Tracer particle follow-up mathematics model, summarizing the development of the PIV test technology for the internal flow field of fan diffuser with diffuser, and the pump four-quadrant test system based on pump full-featured test, can grasp the characteristics of the pump's full operating conditions. Accurately understand the operating range of the pump and maximize the potential of the pump. The research results provide technical means for further improving the reliability of the pump and achieving energy saving. The relevant results have been applied in the fields of 1 million tons of PTA, ship life support system and other fields.
