Reasonable configuration, safe operation, high quality water supply - centrifugal pump

How to rationally configure the power of the motor pump is the key to ensure the safe operation of pump, high-quality water supply, reduce production costs, rational allocation of pump power, pump the best work area of ​​safe operation, the actual situation of our water supply, Reasonable allocation of the importance, reliability and economy. 1, the importance of reasonable configuration of pump equipment. The main task of the water plant is to ensure that the people of the city's production and domestic water supply, the original maximum daily water supply of South Plant 900,000 tons, influent, effluent to meet the pressure in the region, but the last ten years, with the relocation of municipalities, large water users As the quality of life of the people is getting higher and higher, the demand for water quality is getting higher and higher, and the factory water reaches 0.3 NTU. How to ensure the quality of water supply, the company has adopted a series of measures: (a) Adjusting the reasonableness of the pump equipment Configuration, the implementation of the best combination of man-machine. (B) To increase scientific and technological innovation and devote substantial funds to reforming the original outdated water purification equipment. (C) Funds invested, renovation of old equipment, old pipe networks, improvement of hydraulic conditions, installation of static mixers, etc. (D) The installation of forty meters, the use of modern monitoring system, the whole process of water quality monitoring and control, to ensure that quality water. These measures fully demonstrate the importance of rational allocation of pump and water purification equipment. 2, pump equipment, safe operation of the reliability. In order to ensure the safe operation of pump equipment, equipment companies more standardized management of pump equipment, major maintenance once a year, the monthly secondary maintenance, once-a-level maintenance system, these ISO9002 quality management is to ensure that the pump equipment Safe operation of the various measures, in order to ensure the safe operation of the reliability of the technical quality of workers operating training, improvement, the implementation of safety procedures should be strictly enforced, the implementation of these safe operation system is to ensure the reliability of pump operation The guarantee. 3, the safe operation of pump equipment economy. When it comes to economy, it is the cost of making water for enterprises, including electricity, alum, chlorine and ammonia. It is necessary to control the economic activities of enterprises and raise the economy in the safest mode of operation, the optimal mode of operation and the lowest cost of water system Benefit, in this area enterprises have accumulated some experience. Such as: the safest mode of operation, Shanghai's urban water supply network is interoperable, the company's central dispatch room to control the pressure of water supply in the region, too high likely to cause squibs, to the people, the country caused property damage, water pressure is too low, Affect some users of water, resulting in a bad corporate image. Therefore, the pressure during the day to maintain the region is 30-35 kPa, nighttime pressure stays below 30 kPa. According to the requirements of pipe network pressure, high-lift pump open during the day and high-lift and low-lift combination at night effectively control the pressure of the factory water to ensure the water supply of the regional pipe network and the hotel's tall buildings. By adopting these best pump combinations, Not only saving power consumption, but also reasonably control the pressure, these methods to ensure the safe operation of pump equipment economy. With the continuous development of science and technology, the degree of modernization of pumps has been continuously improved, reducing many man-made management operations. Mostly now using computer monitoring of automatic mode of operation, which also raised the operator's own quality requirements. Because of a pump abnormal situation will affect the entire water supply network, with serious consequences. After several years of practical work and theoretical study, the learned knowledge can be applied to practical work, and the water distribution and scheduling can be reasonably arranged. Utilizing the characteristics of each pump to reach the maximum output of the pump with the least power, Best operating condition And to be safe, high quality, low consumption of water supply!
