Problems solved by technology
[0003] Restricted by power formation conditions, the current mainstream U-shaped oscillation tube still uses pistons, cylinders, wave generators and other equipment to continuously provide power conditions. However, in this case, forced oscillation requires continuous input power, which is neither environmentally friendly nor economical. Difficulties in promoting applications

Embodiment Construction
[0018] An energy-saving pneumatic free-oscillating tube of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings.
[0019] An energy-saving air pressure free oscillating tube of the present invention adopts electric inflating technology, uses an air pump to inject gas into one end of the U-shaped oscillating tube filled with water column, and pumps air to the cylinder connected to the piston while inflating, so that the piston moves down , to block the air outlet. After the inflation is completed, inflate the cylinder reversely to make the piston move up, deflate, and the liquid in the U-shaped oscillating tube begins to oscillate freely.
[0020] like figure 1 As shown, an energy-saving air pressure free oscillation tube of the present invention includes a U-shaped oscillation tube 1 and a support platform 2 for supporting and fixing the U-shaped oscillation tube 1, and the two ports of the U-shaped oscillatio...

An energy-saving pneumatic free oscillating tube includes an oscillating U-tube and a support platform used for supporting and fixing the oscillating U-tube, wherein two ports of the oscillating U-tube are fixed at the upper part of the support platform and both adopt non-closed opening structures; a piston and a cylinder are arranged above one of the two ports, the piston is used for closing or opening the port, and the cylinder is used for driving the piston to move up and down; a gas inlet is formed in the tube wall of the port with the piston and is connected with a gas outlet of a gas pump through a pipeline; the gas outlet of the gas pump is further connected with a gas inlet of a three-way valve through a gas circuit; a gas port of the three-way valve is connected with a gas port of the cylinder through a pipeline, and the other gas port of the three-way valve is connected with the other gas port of the cylinder through a pipeline. The energy-saving pneumatic free oscillating tube disclosed by the invention provides an efficient and reliable power technology; generated oscillatory flows are in a free oscillating status, so that power conditions needn't be continuously provided, which meets the requirements for economization and environmental protection, and achieves the applicability for practical production and life.
Description
technical field [0001] The invention relates to a fluid dynamics model. In particular, it relates to an energy-saving air pressure free oscillation tube used in the pressure principle experiment of physics. Background technique [0002] The method of using a medium such as a piston to push a stationary fluid to generate an oscillating flow is an important technical means of fluid mechanics experiments and is very important in hydrodynamic research. As a commonly used experimental instrument, U-shaped tubes are generally U-shaped transparent glass tubes or plastic tubes, which can hold liquids or solids. They are widely used in physical experiments and chemical experiments, such as measuring liquid density, making oscillating flow Experiments, making pressure gauges, etc. The U-shaped oscillating tube applies the principle of connector and pressure, and the liquid in the tube forms an oscillating flow under the action of external pressure. The U-shaped oscillating tube has...
