Su Qingrong, Engineer of Technical Equipment Department of City Water Company, was very excited to tell the author: "After we painted the pump with the new industrial paint in the United States, we reduced the food intake of these tigers to eat electricity, saving 158,400 kWh , The company can save 80,000 yuan a year to do it! "City water company responsible for the city's water supply task force, there are only white turtle water plant has a flow of 2160 cubic meters / hour of large-scale water intake pumps 9, in normal operation, each shift To open 7 to 8 pumps, each pump 24 hours average power consumption of about 10,000 degrees, each pump consumes about 4,500 yuan a day. 8 pumps consume 200 million degrees per month, electricity bill more than 1 million yuan. In the company's production and operation, the consumption of electricity has become the largest company's expenses. By adopting a method of avoiding peaks and valleys, they avoided the peak of electricity consumption during the day and increased the production of tap water at night when the electricity bill was low, which saved electricity costs by $ 2.1 million each year. In order to minimize power consumption, the company decided to invest 15,000 yuan, the United States Belzona's ultra-smooth metal coating on the pump smear transformation, by increasing the pump casing and the smoothness of the impeller to improve water flow in the pump housing Flow conditions, reduce resistance, improve pump efficiency. In May, the company carried out coating treatment on No.9 water intake pump at Baiguishan Water Plant. After 712 hours of electricity measurement and tracking, it found that after the coating treatment, the electricity consumption per ton of water was reduced from 223 degrees before transformation to 215 degrees. Every day Saving 440 degrees, saving 13,200 degrees per month, the daily electricity savings equivalent to 220 yuan, each pump can save 80,000 yuan throughout the year. If the operation of the mainframe pump after the transformation, each year can save electricity and materials costs more than 50 million.
