To give everyone a practical understanding of the effects of energy-saving upgrades, we are sharing several recent success stories from our company: 1. In a company in Binzhou, after replacing the #qsn300-m9 double-suction pump with our specially designed high-efficiency impellers, the motor current dropped from 280A to 230A while maintaining the same flow rate, resulting in an energy-saving rate of 17.8%. 2. In another company in Binzhou, after installing the specially designed high-efficiency impellers on the #qsn250-m6 double-suction pump, the flow rate increased slightly, yet the motor current decreased from 223A to 153.8A, achieving an energy-saving rate of 30%； 3. A double-suction pump model #qsn250-m9 at a chemical company in Binzhou was upgraded for increased capacity; with the same valves and piping system, its flow rate increased from 490 cubic meters per hour to 560 cubic meters per hour, and its efficiency also improved significantly. 4. The circulating water pump 24SH-9B of a certain chemical company has a flow rate of 2,800 cubic meters per hour, a head of 56 meters, and an electric motor with a power rating of 560 KW. It originally consumed 520 kWh of electricity per hour; after replacing it with our high-efficiency impeller, the electricity consumption dropped to 470 kWh per hour, resulting in a savings of 50 kWh. 5. A company replaced its OS350-510B double-suction pump with our energy-saving pumps, achieving an energy savings rate of 15%. 6. A company in Binzhou replaced its 10sh-6A water pump with our energy-saving pumps; the current required for the same flow rate decreased from 145A to 105A, resulting in an energy savings rate of 27%. To dispel customers’ concerns about whether the energy-saving upgrades are truly effective, our company records parameters such as flow rate and current with the customers before the upgrades are carried out, and then records these parameters again after the upgrades are complete. By adjusting the flow rates to be the same and conducting comparisons, we allow the customers to verify the results themselves, ensuring authenticity and reliability. Before the renovation, our company will first inspect the site, assess its operating conditions, determine the appropriate parameters for the water pumps, design and manufacture specialized energy-saving impellers for these pumps, and develop a comprehensive plan for the technical renovation. Our company will cover all the costs associated with the renovation; the customer does not need to pay anything until the renovation is completed and inspected. All energy-saving water pumps, impellers, and other components are provided by our company, and we assume all related costs and risks. In other words, the renovation is carried out first, and payment is made only afterward. If the renovation is not successful, no fee will be charged; payment is made only after it is proven that money has been saved as a result of the renovation. For the clients we serve, we generally first modify one unit, gain their trust and appreciation, and then proceed to modify several units. Designing and manufacturing high-efficiency water pumps or high-efficiency impellers to replace old ones is the main approach for energy-saving upgrades of water pumps. As an advanced technology for designing high-efficiency impellers, the three-dimensional flow impeller technology has been widely used in China’s impeller machinery industry, playing a crucial role in the energy-saving transformation of water pumps; it is attracting increasing attention and being increasingly promoted for use. Implementation method for the technical renovation project of three-dimensional flow impellers: Based on the actual operating conditions of the user’s water pumps, and with the goal of fully meeting those operational requirements, this approach utilizes the theory of full three-dimensional flow involving jets and wakes. Design software such as PCAD and CFD is employed, along with the extensive experience accumulated by senior engineers, to carry out comprehensive optimization. High-efficiency three-dimensional flow impellers that can be interchanged are then redesigned and manufactured; these impellers can be installed directly within the original pump casing without any modifications to the existing equipment, motors, pipelines, etc. The installation process is simple and fast, the project is safe and easy to implement, and it offers significant energy-saving benefits. It can thus be considered the preferred solution for energy-saving renovations of water pumps. The total amount of the energy-saving service fee we charge is determined by taking into account factors such as the complexity of the project, the amount of investment required, the size of the water pumps, the extent of energy savings, and electricity prices. The amount varies depending on the specific circumstances, but it generally does not exceed the amount saved in electricity costs over 10 months. In other words, customers are assured that the savings they achieve in electricity costs within one year will be greater than the total amount of service fees paid; there is a surplus left after the service fees are settled for that year. Compared to the electricity costs incurred before the renovation, the cost of the energy-saving renovation service does not impose any additional burden on the customer; on the contrary, the customer can save this amount of money in the same year, and even earn a profit as well. Once this service fee is paid, no further charges will be incurred. The energy-saving equipment provided by our company, as well as the energy savings it generates, all belong to the customer, who will continue to benefit from them in the long term. Customers only experience success, no failures – true zero risk, zero investment, saving time, effort, and money. Based in Zibo and serving the entire Shandong region, our company is eager to work together with pump users who place emphasis on energy savings and reduced consumption.
