21世纪以来,调查发现人们关注最多的话题是能源、效率与自动化。随着各种能源的逐渐枯竭和人们对能源需求的不断上升,能源的高效利用与持续循环利用已成为热门话题。而在所有的机械设备中,离心泵是耗能大户,但离心泵在各个领域应用非常广泛,所以改善离心泵的性能、降低能耗成为当务之急。 Since the 21st century, the survey found that the topics that people are most concerned about are energy, efficiency and automation. With the gradual depletion of various energy sources and the increasing demand for energy, the efficient use of energy and continuous recycling have become hot topics. In all the machinery and equipment, centrifugal pumps are energy-hungry, but the centrifugal pump is widely used in various fields, so to improve the performance of centrifugal pumps to reduce energy consumption has become a top priority.
