Problems solved by technology

The pipe network system forms heat supply losses at both ends of the heat exchange points of heat exchange stations, unit buildings, units, and heat users. Due to different loads, the heat supply is unbalanced and affects the heating efficiency.
[0006] In short, the existing water supply and heat supply pipe network system cannot realize the hydraulic balance adjustment of the regional network, resulting in low load, high power and heat consumption, and affecting water supply and heat supply efficiency.

Abstract

The invention discloses a control system for equal pressure difference flow increasing. A pipe network system is divided into an operation network and a load network, and a venturi type injection pumpis installed at the front end of the load network. The invention further discloses a control method for equal pressure difference flow increasing. According to the system and method, the hydraulic imbalance of a heat pipe network can be solved, the load on the heat pipe network is improved, the power consumption of the heat pipe network is reduced, the heat consumption of the heat pipe network system is reduced, and the water supply or heat supply efficiency of the heat pipe network is improved.

Description

technical field [0001] The invention relates to a water supply and heat supply technology, in particular to a control system and method for increasing flow with equal pressure difference. Background technique [0002] Venturi tube is a device for measuring fluid pressure difference. Venturi tube (Venturi tube) is divided into built-in Venturi tube and plug-in Venturi tube according to the structure. Good results have been obtained in the measurement of combustion-supporting air, cold air, and gas (blast furnace gas, coke oven gas, converter gas) of hot blast stoves in iron and steel plants, and the measurement of primary air and secondary air of boilers in thermal power plants with large pipe diameters and low flow rates. It solves the problem of accurate measurement of various gas flows at medium and low pressures, large pipe diameters, and low flow rates in current industrial enterprises. Fluid measuring device with wide measuring range and easy installation. The unique ...
