Circulating pump real-time adjustment control system developed
Aiming at the design and operation mode of quality adjustment, quality mixing adjustment or distributed adjustment commonly used in domestic and international primary circulation pumps, an innovative energy-saving control system has been developed after 5 years of development and test in China. It takes the national patent as the core of technology, based on the related theories of fluid mechanics and thermal engineering, succeeds in adjusting the amount of circulating pump, which is the first in the world. And won the national invention patents, the maximum power-saving rate of up to 80%. A circulating pump real-time adjustment system for the design capacity of 1 ~ 1.5kW per thousand square meters of heating systems, the saving rate of up to 50 to 80%, and nowadays more advanced pump distributed design The calculated power saving rate was 33.8%. The system from the functional design and operational regulation, the first to ensure the stable and safe operation of the heating system as the starting point, the application of the system, without the transformation of large equipment, and technical programs one-time commissioning is completed, and then automatically adjust the operation . If the original design of a reasonable quality control system based on the transformation of construction per square meter of heating area of ​​0.15 to 0.3 yuan investment in 1 to 2 heating period to recover investment. The mentioned saving rate is obtained when the initial design of a circulating pump is relatively reasonable. For the general heating system in the industry, the operating capacity of a circulating pump is about 1 ~ 1.5kW per 10,000 square meters of heating area. For such a system, if the circulating pump real-time regulating control system is adopted, the actual saving rate Up to 50 ~ 80%. For those who originally designed, run, adjust the unreasonable heating area of ​​10,000 square meters of heating a pump up to 2 ~ 3kW or more systems, based on the energy-saving technology, coupled with the original design and use of an unreasonable and wasteful Part, you can double the power. Beijing heating plant in the 2004-2005 heating period, the use of real-time adjustment control system after the test run, the 600,000 square meters of heating area, a pump capacity of 1.25kW per thousand square meters, the current saving rate of 68%; 2005-2006 heating period saving rate of 72%; 2006-2007 heating period, as of February 2007, saving rate of 79%. Another example is a heating plant in Beijing, the heating area of ​​1.85 million square meters, a pump capacity of 1.03kW per million square meters, as of February 2007, the saving rate of 53%, the plant only modified the circulating pump control cabinet, Pipe network and heat exchanger station did not make any transformation, they have achieved such a satisfactory result (1.9 heating period will recover the investment cost).
