Hydraulic performance measuring method and apparatus for heat distribution pipe network

Abstract

A heating distribution network hydraulic work condition measuring method and equipment belong to heat supply network move bugging field. Set temperature sensor and hot water runoff sensor on the entrance of each heating spur track to heating distribution network to test the water supply temperature tg and actual testing runoff Lt of the hot water to the heating spur track. Set temperature sensor on the export to heating spur track, inside and outside room of the consumer to test the backwater th to heating spur track, indoor temperature tn and outdoor temperature tw of the consumer. The said sensor send testing value to the data disposal system and the said system deals with the data to get water power maladjustment x of each heating spur track and fact demand flux Ls to each heating user. It ensures the fact demand flux of heating distribution network based on the locale fact load of heating user without destroy the existing pipe system. Its operation is easy with few test parameters for using at locale.

Description

technical field [0001] The present invention relates to a measurement method and device in the field of heating pipe network operation and debugging, in particular to a thermal measuring device suitable for on-site measurement, initial adjustment, and heat pipe network reconstruction and debugging of the hydraulic working conditions of the built heat pipe network. A method and device for measuring hydraulic conditions of a pipe network. Background technique [0002] In the heating system, hydraulic imbalance refers to the inconsistency between the actual flow rate and the specified flow rate of each thermal station (or heat user) in the hot water heating pipe network. (Heat station or heat user) The required flow (heat) is allocated to each user, resulting in the phenomenon of uneven cold and heat in different locations. The degree of hydraulic imbalance in the heating system is measured by hydraulic imbalance. Distribute the flow according to the user's heat load, so that...
