Cam lobe pump is a versatile machine used in petroleum, chemical, printing and dyeing, animal husbandry, power metallurgy, shipbuilding, light industry, agriculture, civil and national defense sectors, and occupies an important position in the national economy. The electrical energy consumption of pumps accounts for more than 21% of the national electrical energy consumption. Therefore, vigorously reduce the energy consumption of the pump, with very significant significance for energy conservation. In recent years, our pump industry has designed and developed many energy-saving products, which have played a positive role in reducing the energy consumption of pumps. The selection of lobe lobe pump mainly involves the working medium, working medium characteristics, head, flow rate, ambient temperature and other data, the appropriate lobe pump not only works smoothly, long life, and can save costs for the user to a large extent. However, in various fields of national economy, due to unreasonable selection, many pumps are in unreasonable operating conditions, low operating efficiency, wasting a lot of energy. There are also pumps due to unreasonable selection, camber lobe pump can not be used at all, or the use of maintenance costs increase, low economic benefits. This shows that reasonable pump selection is equally important for energy saving. The so-called reasonable selection of pumps is to consider the comprehensive technical and economic indicators such as the investment and operating costs of pump units and pump stations, so that they comply with the principles of economy, safety and applicability. Specifically, there are the following aspects: the requirements of flow and head must be met, that is, the operating condition point of the pump (the intersection of the characteristic curve of the device and the performance curve of the pump) is often kept in the zone of operation, so that it is not only power-saving but also not easy to damage the machine parts. The selected lobe lobe pump should be small in size, light in weight and cheap in cost, but also have good characteristics and high efficiency. It should have good anti-cavitation performance, which can reduce the excavation depth of the pump room and not make cavitation of the lobe lobe pump occur, and run smoothly and have a long life. Build the pumping station according to the selected lobe lobe pump, with less engineering investment and low operation cost.
