Frequency control of circulating water pump

In the current use of the vacuum pump unit of the circulating water pump frequency control has a certain amount of research, and now the economic benefits of this unit is given certain, if you have any questions about the realization of the vacuum pump unit of the circulating water pump frequency control.

In the realization of water ring vacuum pump combined with engineering examples, the typical working condition time period method will be adopted to simplify the calculation of total energy consumption of pump operation. In this paper, the energy-saving characteristics of different parallel units and different operation control modes are analyzed. Based on the similarity law of water pump, the equal efficiency curve method to determine the efficiency of water pump at various operating points is given. The analysis results show that for the common control mode of water system, the relationship between the speed (flow) ratio of water pump and the power ratio of shaft is not tenable; for the water system with three pumps running in parallel, the efficiency of the rated operating point of water pump can be used to replace the efficiency of the typical operating point, so that the calculation is greatly simplified; for the air-conditioning water system, the frequency control device of water pump is adopted, its economy is certain, and The economy is closely related to the type of project, and the energy saving of VFD operation of circulating water pump in air conditioning system has been generally recognized in the industry.

For the realization of the frequency conversion and speed regulation of the circulating water pump of the vacuum pump unit, I hope it can help you, and in the later use, you can better understand the use principle and create higher profits for users.
