This paper researches the jet pump performance in the water supply of hydropower station technology,through numerical value calculation to determine the geometric size of the flow components,and ensure the efficiency to be the highest value,and Derives the expression for efficiency and performance,protracts operating characteristics of jet pump and efficiency feature curve under different area.

Introduction and application of technical water supply system for Xiaolangdi Hydropower Plant;

Aiming at the faults of the technical water supply system of Unit 1 at the Xiaoshan Hydropower Station,such as solenoid valve block,oil leak,fluctuation of pressure,etc.

and to counter the analyzed cause of fault of technical water supply pump pf four pumping stations in urban flood control project of Jiaxing City, it is used some methods such as to implement back-flushing, adjust the poison of intake, reform sewage barrage and make pretreatment etc.

Aiming at the problems existed in the teaching of distribution technology course and the demand of the teaching reform, this paper discusses the combining of teaching contents about thoughts, methodology and principles.

Expound constitute principle and realize method for a branch of learning teacing material, develop stucture of pattern lump for a branch of learning teaching material of the distribution technology.

How to face to new century of heating technology;
