Debugging method and system for hydraulic balance

Abstract

The invention discloses a debugging method and system for hydraulic balance. The debugging method comprises the steps that a product identification of a hydraulic balance valve to be debugged is determined, and a valve parameter curve corresponding to the product identification is obtained from a preset data base; the valve opening degree of the hydraulic balance valve is obtained, and a flow coefficient corresponding to the valve opening degree is determined according to the valve parameter curve; and the pressure difference of the two ends of the hydraulic balance valve is obtained, and the current flow flowing through the hydraulic balance valve is worked out according to the pressure difference and the flow coefficient. According to the debugging method and system for hydraulic balance, the valve parameter curve corresponding to the product identification of the hydraulic balance valve to be debugged is obtained from the preset data base, and accordingly the flow coefficient corresponding to the valve opening degree of the hydraulic balance valve can be determined; then, the current flow flowing through the hydraulic balance valve can be worked out by combining the pressure difference obtained through measurement; and thus the limitation that a debugging instrument only can be used with the hydraulic balance valve in a matched mode can be relieved, and the debugging difficulty of hydraulic balance is reduced.

Description

technical field [0001] The application relates to the technical field of debugging of heating and air-conditioning water systems, in particular to a method and system for debugging hydraulic balance. Background technique [0002] Hydraulic balance technology is an important technology in heating and air-conditioning water systems, which directly affects the use effect of heating and air-conditioning and system energy saving. The hydraulic imbalance is a chronic disease in the heating and air conditioning water system, and the phenomenon of hydraulic imbalance will cause serious uneven flow of cold and hot water in the heating and air conditioning system. [0003] Taking the heating system as an example, in the design calculation, each building is calculated and assigned a fixed hot water circulation flow, and the hot water is supplied according to this flow, so that the room temperature of the building can meet the design requirements, but in actual operation, due to constru...

Problems solved by technology

[0005] However, because the valve parameters solidified inside the debugging instruments produced by different manufacturers are different, the debugging instruments can only be used with the matching hydraulic balance valve. When the debugging instrument and the hydraulic balancing valve are not matched, accurate debugging cannot be performed. Balanced debugging is very difficult
