The energy-saving problem of oil pumps has always been a topic that engineers have been studying, because oil pumps are produced in a large number and have a wide range of applications, which can involve various departments such as petroleum, chemical industry, medicine, and food. Moreover, according to national statistics, the power consumption of pump products accounts for about 20% of the country's total power generation and 5% of the country's total fuel consumption. Therefore, strengthening the energy-saving technical work of the pump industry has become an important part of the current national energy-saving work. The "China Energy Conservation Technology Policy Outline" jointly promulgated by the Ministry of Science and Technology and the National Development and Reform Commission clearly states that it is necessary to "develop and promote high-efficiency pump equipment. The future development prospects of pumps should be energy-saving and high-efficiency development. This requires oil pump companies to be serious. Think about how to develop your own business. The energy-saving method adopted in the future development is mainly to make the pump unit (pump, prime mover and rotating part) run at the highest efficiency, so that the energy input from the outside is reduced to lowest point.
