由于设计或施工的缺失,在水力管网系统中,经常会产生水力失调现象,即当某些环路存在剩余压头时,这些环路的实际流量就将超过设计流量,致使其它环路的实际流量达不到设计流量。这种水力失调是管网系统运行中,特别供冷面积较大或管路较长时常遇到的问题。如不采取有效改善措施,将带来大量的能源浪费,并使供冷品质低下。本文结合我司冷冻水系统运行状况,说明采用平衡阀对水力失调系统进行改造,将产生的节能效益。 Due to the lack of design or construction, hydraulic imbalance often occurs in the hydraulic pipe network system. When there are surplus heads in some loops, the actual flow of these loops will exceed the design flow, resulting in other loops. The actual traffic cannot reach the design flow. This kind of hydraulic imbalance is a problem often encountered in the operation of the pipe network system, especially when the cooling area is large or the pipeline is long. Failure to adopt effective improvement measures will result in a large amount of energy waste and low quality of cooling. This article combines the operating status of our chilled water system to illustrate the use of a balancing valve to reform the hydraulic imbalance system, which will result in energy-saving benefits.
