Cold and hot shock and performance test bench: help to create high-quality nuclear pump products

Nuclear pumps are the core components that ensure the safe and efficient operation of nuclear power plants. Compared to pump products in other fields, nuclear power pumps have higher requirements for performance, structure, materials, and inspection. Any slight negligence may cause irreversible safety accidents. Therefore, ensuring the operational reliability of such pump products and eliminating safety hazards during operation has become the primary goal of current pump companies. One of a group of domestic enterprises that focus on research and manufacturing of pumps and pump systems, has been deeply involved in the water pump market for many years. With the mission of "leading the rise of China's pump industry", we adhere to independent innovation and strive to develop and produce high-quality water pump products. Our aim is to demonstrate the strength of Chinese manufacturing to the world by driving the energy efficiency upgrade of the industrial system. In order to realize the independent design and domestic manufacturing of China's nuclear secondary and tertiary pumps as soon as possible, and ensure the safe development of the national economy, as early as 2010, we invested in the construction of a cold and hot shock and performance test bench. Cold and hot shock and performance test bench With a special investment of 25 million yuan, the cold and hot shock and performance test bed was independently designed, developed and built, covering an area of 1500 m2. It can carry out cold and hot hydraulic performance, cold and hot shock, impurities, cold and hot durability, startup, idle running and other tests of various nuclear grade pumps and pumps used in special fields, so as to achieve a fast thermal shock of 4 to 250 ℃ within 5 seconds, and sustainable hot operation after thermal shock. Compared with the stepped test data in the same industry, with the combination of high-speed data acquisition card and transient condition acquisition system, the test bench data presents a smooth curve and reaches level 1 accuracy. As one of the test benches in the domestic nuclear power pump manufacturing field, the completion of the thermal shock and performance test bench also provides a high-quality scientific research base for the localization research and development of nuclear power equipment.

Encourage the "pump" to break new paths! 2023 Supplier Conference of Sany Heavy Industry Pump Road Division Held

Spring is warm and flowers bloom, and all things revive. On March 6th, the 2023 Supplier Conference of Sany Heavy Industry's Pump Road Division, themed "Leading the Way with Strong Pump Development and Joining Hands to Explore New Roads," was held in Changsha Industrial Park. Representatives of 182 suppliers from around the world attended the event to jointly depict the new grand plan of pump road in 2023. Xiang Ru'an, Senior Vice President of Sany Heavy Industry and Chairman of the Pump Road Business Unit, and Tan Bo, General Manager, attended the conference. At the meeting, Xiang Ruan expressed gratitude to his suppliers and partners for their long-term strong support for the cause of Sany. He expressed that the two great opportunities, the Chinese Dream of the great rejuvenation of the Chinese nation and the super technology window of the fourth industrial revolution combined with the third energy revolution, have painted a beautiful future for the development of Sany's intelligence, electrification, and internationalization. He hopes that all suppliers and partners seize the opportunity and actively guarantee supply, Both sides will further deepen cooperation, work together for a win-win situation, and create a better 2023 together. Tan Bo gave a business report with the theme of "efficiency, health, and sustainability", reviewed the achievements of 2022, and analyzed the new situation and opportunities in the concrete machinery and road machinery markets in 2023. He hoped that both sides would continue to cooperate, innovate, and reduce costs, establish confidence, and work together to achieve steady progress.

Lithium dominates the world, and intelligent pumps assist the new energy lithium battery industry

Benefiting from the rapid development of the new energy vehicle industry, research on new materials for lithium batteries has become increasingly popular. Among them, all solid-state lithium-ion thin film batteries are increasingly receiving attention due to their higher safety advantages. Thin film solid-state lithium batteries are a new type of lithium-ion battery with a new structure developed on the basis of traditional lithium-ion batteries. Its basic working principle is similar to that of traditional lithium-ion batteries, that is, during the charging process, Li+detaches from the positive electrode film and undergoes a reduction reaction in the negative electrode film through the electrolyte; The discharge process is the opposite. Electrolyte plays a crucial role in the process, which directly affects the charge discharge ratio, cycle life, self-discharge, safety and high and low temperature performance of thin film batteries. Taking the practical application of an all solid-state thin film lithium battery production test line as an example, a customer from Lange needs three pumps in a group to transport reagents at different time points in the electrolyte testing process, with one hour as a cycle and 8 consecutive hours of operation per day.
