The selection of water pump is not distressed. See here for the correct selection of specifications.

At present, in various fields of the national economy, due to unreasonable selection, many pumps are in unreasonable operating conditions, low operating efficiency, and waste a lot of energy. There are pumps due to unreasonable selection, simply can not be used, or the use of maintenance costs increased, low economic efficiency. It can be seen that reasonable selection of pumps is also of great significance to energy conservation. The so-called reasonable selection of pumps is to comprehensively consider the investment and operating costs of pump units and pumping stations and other comprehensive technical and economic indicators, so that it conforms to the principles of economy, safety and application.
The selection of the pump mainly involves the working medium, the characteristics of the working medium, the head, the flow rate, the ambient temperature and other data. The suitable pump not only works smoothly, has a long life, but also can save the cost for the user to the greatest extent.
Water pump is a kind of general-purpose machinery and equipment, which is widely used in petroleum, chemical industry, electric power metallurgy, mining, shipbuilding, light industry, agriculture, civil and national defense departments, occupies an important position in the national economy. According to statistics, China's pump output reached 5.256 million sets. The electric energy consumption of the pump accounts for more than 21% of the national electric energy consumption. Therefore, it is of great significance to reduce the energy consumption of the pump and to save energy. In recent years, our pump industry has designed and developed many high-efficiency energy-saving products, such as IHF, CQB, FSB, UHB and other types of pump products, which have played a positive role in reducing the energy consumption of pumps.
Necessity of correct selection of water pump
However, in various fields of the national economy, due to unreasonable selection, many pumps are in unreasonable operating conditions, low operating efficiency, and waste a lot of energy. There are pumps due to unreasonable selection, simply can not be used, or the use of maintenance costs increased, low economic efficiency. It can be seen that reasonable selection of pumps is also of great significance to energy conservation. The so-called reasonable selection of pumps is to comprehensively consider the investment and operating costs of pump units and pumping stations and other comprehensive technical and economic indicators, so that it conforms to the principles of economy, safety and application. Specifically, there are the following aspects: must meet the requirements of the use of flow and head, that is, the operating point of the pump (the intersection of the device characteristic curve and the performance curve of the pump) is often kept in the efficient range of operation, which saves power and is not easy to damage the parts. The selected water pump should not only be small in size, light in weight, low in cost, but also have good characteristics and high efficiency. It has good anti-cavitation performance, which can not only reduce the excavation depth of the pump room, but also prevent the pump from cavitation, which has stable operation and long service life. According to the selected pump to build pumping station, the project investment is small, low operating costs.
