Experimental apparatus for pressure regulating chamber teaching

Abstract

The invention discloses a surge-chamber teaching experiment device, which is characterized by the following: setting the circulation pump between the inlet of water-supply radiator and outlet of water-drain radiator; connecting the inlet and outlet of diversion pipe with the inlet and outlet of water-supply radiator; setting two change-over valves between the bent tube of diversion pipe and outlet of diversion pipe separately; paralleling two change-over valves with the differential surge-chamber and impedance surge-chamber, which couple the rapid close valve; paralleling the water-return pipe within gate valve and electromagnetic flowmeter between diversion pipe and water-drain radiator. The device can finish different kinds of surge-chamber experiment on one test bench through changing parameters of influential surge-chamber hydraulic phenomenon, which is recorded the wave fluctuation course through the computer data collection system.

Description

technical field [0001] The invention relates to a surge chamber teaching experiment device capable of completing different types of surge chamber experiments on one test bench, and belongs to the technical field of teaching instruments including hydraulics and water conservancy engineering. Background technique [0002] The surge chamber is an important building to reduce the water hammer pressure and stabilize the operation of the unit in the water delivery system of the hydropower station and the pumping station of the water conservancy and hydropower project. The water flow phenomenon in the surge chamber is complex, and there are many factors affecting its hydraulic phenomenon, such as the type of surge chamber, the length of the water delivery pipeline and head loss, the hydraulic impedance of the water flowing into / out of the surge chamber, the water level of the reservoir, the opening and closing rules of the unit and Time, etc., and it is difficult to see the hydraul...

Problems solved by technology

The water flow phenomenon in the surge chamber is complex, and there are many factors affecting its hydraulic phenomenon, such as the type of surge chamber, the length of the water delivery pipeline and head loss, the hydraulic impedance of the water flowing into / out of the surge chamber, the water level of the reservoir, the opening and closing rules of the unit and Time, etc., and it is difficult to see the hydraulic phenomenon of the surge chamber in the actual project. Even the experimental model of the surge chamber of individual actual projects in the laboratory cannot meet the teaching requirements and reflect the influence of the above factors one by one.
