The stainless steel sanitary centrifugal pump is a single-suction, single-stage, centrifugal sanitary pump, suitable for conveying various liquids. It is an indispensable conveying equipment for the pharmaceutical, food, chemical and other industries, and its application range is very broad. However, in recent years, with the strengthening of environmental awareness, energy-saving requirements for stainless steel sanitary-grade centrifugal pumps have become higher and higher in all walks of life.
On August 27th, the website of the National Energy Administration released the target of ultra-low emission and energy-saving renovation of coal-fired power in all provinces (autonomous regions and municipalities) in 2018, and requested to continue to intensify efforts to promote ultra-low emission and energy-saving transformation of coal-fired power. The central region strives to be in 2018. It was basically completed years ago and the western region was completed in 2020. As one of the high-energy-consuming electrical equipment, the energy-saving retrofit work of stainless steel sanitary-grade centrifugal pumps has also attracted the attention of enterprises.
For stainless steel sanitary centrifugal pumps, how to achieve energy saving and emission reduction, the effect of effective use is not only the direction of the country, but also the issue that enterprises and individuals should pay attention to. Only by achieving the goal of energy saving and high efficiency can we adapt to the trend of national development and reduce the cost of electricity consumption of enterprises and bring more benefits to enterprises.
So how do you get stainless steel hygienic centrifugal pumps to run more efficiently? The technical staff of a company summarizes the following points and is only for reference in the industry.
Correct selection of the size of the centrifugal pump
According to the industry, the choice of stainless steel sanitary grade centrifugal pump should be used in the high efficiency zone to avoid the waste of large horse-drawn trolleys. For example, in practice, only 3kw of sanitary pump is needed. If 7.5kw is forcibly installed, this will result in waste of resources, and it will easily cause overload and empty play, causing certain damage to the centrifugal pump.
Control the volatility of water pressure
It is reported that because the stainless steel sanitary centrifugal pump runs in a curve mode, as the flow rate increases, the lift is reduced.
At the same time, we should also pay attention to controlling the fluctuation of the water pressure of the sanitary pump to ensure the stability of the outflow, so as to promote the implementation of energy-saving technologies.
Optimize the operation of the centrifugal pump
Combined with the hydraulic calculation of the pipe network, the accurate and reasonable selection of the stainless steel sanitary centrifugal pump is the basis for optimizing the pump selection and ensuring its stable operation in the high efficiency zone. When calculating the relevant parameters of the sanitary pump operation, the wear of the impeller generated by the stainless steel sanitary centrifugal pump in long-term operation should be taken into consideration, and the applicability of the safety factor should be improved.
It is worth noting that the pump selection should not be too large, otherwise it may cause inefficient operation and increase energy consumption, which is not worth the loss.
Avoid high lift and low use
The industry said that stainless steel sanitary grade centrifugal pumps should be avoided as much as possible. If you only need 10m lift, try to choose a slightly higher lift of 10m. Therefore, if the sanitary pump with too high lift is selected, it will not be reached in actual use, which will result in a low inflection point of performance, resulting in waste of performance.
In addition, if the variable speed stainless steel sanitary centrifugal pump is operated at the rated speed, it should be at the end of the efficient operation of the sanitary pump.
It is understood that when selecting the speed-regulating sanitary centrifugal pump, the second-flow data is mainly referred to, and the working point is the operating point that meets the second-flow rate. However, the time involved in the second-flow in the pipe network is very short, and most of the pumps are below the design value. Run under conditions.
Therefore, if the working point of the pump is at the end position of the high efficiency zone, the pump can achieve efficient and stable operation and achieve good energy saving effect.
