1. There are misunderstandings about the energy saving of water pumps
In the past, our understanding of pump energy saving was mainly to improve the efficiency indicators of water pumps, in fact, this is a misunderstanding of the understanding of water pump energy saving, which is a one-sided understanding. The range of energy saving we are talking about is not only an efficiency index, but also includes the stability of the pump's performance, the life of the pump, the saving of materials and other factors. Then specific to the use environment of the pump, we should also carry out targeted energy-saving design, such as the sealing performance of the pump, the hydraulic performance of the pump, the high temperature resistance of the pump, etc., which should be designed for different environments and unused uses. Therefore, the energy-saving research of water pump is a very complex work, and our understanding of the concept of energy-saving should not be too one-sided, but should have a comprehensive and overall understanding.
2. Factors of the user unit and individual
When purchasing pumps, users and people often pay attention to whether the pump meets their own needs and whether the price is relatively cheap, but they do not care much about the energy-saving technical indicators of the pump. This demand from consumers has also discouraged pump design and manufacturing units from carrying out energy-saving technological innovation. And a large part of consumers in the choice of pumps, to choose the flow and head margin of the pump is too large, to ensure that they can meet their own needs, such a consequence directly causes the pump in the use process, the actual operating efficiency is much lower than the highest efficiency of the pump, has not been able to operate in the high-efficiency area. In addition, in the process of use, due to the management and inspection of the user unit is not strict, the operation and maintenance are not appropriate, and the maintenance is not timely, etc., the pump often fails in the process of use, resulting in a lot of energy waste.
