The characteristics of independent hydropower plants were introduced,the demand,content and method of hydraulic regulation for independent hydropower plants were discussed.

Comprehensive and optimizational regularization of hydraulic stepout in the boiler system;

The solving method of hydraulic stepout in water system of air conditioning;

In this article according to hydraulic stepout and difficult balancing regulation phenomena in outdoor heat supply network a economic and practical regulation method is introduced for hydraulic balancing based upon formula derivation, which realize the proper distribution of discharges between customers and provide guaranteed foundations for heating quality and energy saving.

Analysis on hydraulic disorder of indoor two-pipe reverse-return heating systems with household metering;

Analyses on the hydraulic disorder problems in central heating system for single-storey houses(particularily for reverse return system),and puts forward the direction and measures to solve these problems.

Analyses the causes of hydraulic disorder in heating network and the technology of using hydraulic balance equipment to resolve hydraulic disorder problem,discusses the energy saving of multistage pump systems,and gives recommendations for using multistage pump systems.

In order to discuss the influence on the two-way electric valve for the hydraulic maladjustment caused by the change of hydraulic regime of air conditioning system,the author analyses the force of valve and discusses the valve actuator and its output force,then makes qualitative analysis and quantative analysis on fan-coil water system utilizing pressure diagram display.

The problems include hydraulic maladjustment, system air accumulation, system loss of water and pressure instability, etc.

The article explains the reason and result of hydraulic maladjustment in the heating network at No.
