The problems in the process of fountain pump in use

The problems in the process of fountain pump in use

1, design of fountain pump itself is not high technology content

Fountain pump design in our country at present stage is mainly follow the traditional model conversion method and the velocity coefficient method, the design method to some extent have been out of date, because it is based on the basis of the old fountain pump design experience, in the design process can't surpass the past design level, can't be a breakthrough on efficiency improvement. Plus fountain pump design units to inadequate investment and personnel, fountain pump design personnel of innovation power is insufficient, lack of innovation consciousness, which leads to the fountain pump product technology content is not a quality, the technical content of the fountain pump cannot ascend, energy conservation and nature also cannot do it. Plus fountain pump manufacturing enterprise one-sided emphasis on economic benefits, and neglected the fountain pump energy conservation, the country also does not have this aspect of the policy support and financial incentives, caused the fountain pump manufacturing enterprise of fountain pump energy saving, improve the efficiency of fountain pump no enthusiasm.

2, fountain pump energy saving existence erroneous zone

Our understanding of the fountain pump energy saving in the past was mainly is to improve the efficiency indicators of fountain pump, it is a myth of fountain pump energy saving understanding, is a kind of one-sided understanding. Scope of what we call the energy saving is not only an efficiency index, but also contains the fountain pump performance of stability, fountains, water pump, the material life savings, and other factors. And the use of specific to fountain pump environment, we should also be targeted for energy saving design, such as fountain pump seal performance, fountain pump hydraulic performance, high temperature resistant performance of fountain pump, etc., these are for different environment, not the purpose of the design. So the fountain pump energy saving research is a very complicated work, we also cannot too one-sided understanding of the concept of energy saving, and must have a comprehensive understanding of whole.

3, use the unit and individual factors

Using unit and everyone in purchasing fountain pump, tend to focus on the fountain pump is in line with their own needs, the price is cheaper, but the fountain pump energy saving technology indicators, but don't care much about. The needs of consumers also dismissed fountain pump design and manufacturing units in energy saving technical innovation enthusiasm. When choosing fountain pump, and a large part of the consumers to choose the fountain pump capacity and head allowance is too high, to ensure that can meet the demand of their use, the consequences of such cause the fountain pump in use process, directly to the actual operation efficiency is far lower than the maximum efficiency of fountain pump, always will not operate in high efficient area. In the use process, due to the use of the unit management and inspection is not strict, and improper operation and maintenance, maintenance is not timely, etc., make the fountain pump failure often occurs in use process, cause a lot of energy waste.
