Our company's water pumping consumes a lot of electricity and the monthly electricity bill is e

I've managed water pumps in a mining company before, so I'm a little familiar with this aspect. Our company has also had this problem before. Later, we used Qingdao Cubang energy-saving paint to carry out energy-saving renovations, and the energy consumption was immediately reduced. Let me do the math for you. Take the water pump used by our company as an example. The diameter of the pump impeller is 30 cm, the flow rate is 1200 m/h, the pressure head is 65 m, the rotation speed is 1480 rpm. the efficiency is 83% and the supporting power is 100 kW. When 20 units operate every day, after modification, the minimum energy saving can be 8% according to the electricity cost of 0.7 yuan/kWh, operating 20 units per day and 300 days per year, it can save 33,600 yuan per year and 50 pumps can save 1.68 million yuan.
