Problems in the use of the pump

1. The design technology of the pump itself is not high. At this stage, the design of water pumps in my country mainly follows the traditional model exchange algorithm and speed coefficient method. These design methods are out of date to some extent, because they are based on the old pump design experience On the basis, in the design process, it cannot surpass the past design level, and cannot make a breakthrough in efficiency improvement. In addition, the pump design unit's insufficient investment in technology and personnel, the lack of innovation motivation and lack of innovation awareness of the pump designers, has led to the lack of a qualitative improvement in the technical content of the pump products, and the technical content of the pump itself. Naturally, energy-saving work can't be done to improve. In addition, water pump manufacturers focus on economic benefits and ignore the energy-saving work of water pumps. The state does not have policy support and financial concessions in this regard. This results in water pump manufacturers not being motivated to save energy and improve pump efficiency.　　　　2, there is a misunderstanding about water pump energy saving 　　　　 Our past understanding of water pump energy saving is mainly to improve the efficiency of water pumps. In fact, this is a misunderstanding of water pump energy saving and a one-sided understanding. The energy-saving range we are talking about is not only an efficiency index, but also includes various factors such as the stability of the performance of the pump, the life of the pump, and the saving of materials. In the specific environment of the water pump, we must also carry out targeted energy-saving design, such as the sealing performance of the water pump, the hydraulic performance of the water pump, the high temperature resistance of the water pump, etc., which must be targeted at different environments and different uses Design. Therefore, the energy-saving research of water pumps is a very complex task, and our understanding of energy-saving concepts should not be too one-sided, but a comprehensive and overall understanding.　　　　3. Factors of users and individuals 　　　　 When purchasing water pumps, users and everyone often pay attention to whether the pump meets their own needs and whether the price is cheaper. However, they do not care about the energy-saving technical indicators of the pump. This consumer demand has also dispelled the enthusiasm of pump design units and manufacturing units to carry out energy-saving technological innovations. And when choosing a pump, a large part of consumers should choose a pump with a large flow and head margin to ensure that they can meet their own needs. This consequence will directly cause the actual operating efficiency of the pump to be much lower than that during use. The highest efficiency of the water pump has not been able to operate in the high-efficiency zone. In addition, in the process of use, due to the lack of strict management and inspection of the user unit, improper operation and maintenance, and untimely maintenance, the water pump often fails during use, causing a lot of energy waste.
