Pumping simulator for completely penetrating well under water

Abstract

The complete submersible well pumping simulation device of the present invention comprises a water storage tank with a water pump and a simulation tank. In the simulation tank, there are a water supply chamber, a simulation chamber with an aquifer, and a pumping well. The cross-sectional shape of the simulation chamber is fan-shaped, and the simulation chamber and the water supply chamber , There is a permeable mesh plate between the simulation chamber and the pumping well, and the overflow return chamber in the fixed head overflow tank at the upstream end communicates with the water storage tank through the overflow pipe, and the overflow tank is respectively connected with the water storage tank water pump and water supply through the pipeline. The cavity is connected, and the overflow return cavity in the pumping overflow tank at the downstream end is connected with the water storage tank through the pumping overflow flow measuring tube, and the overflow tank is connected with the pumping hole in the pumping well through a pipe, and at least three sets of pressure measuring glass tubes are vertical Installed on the wall of the simulated cavity, one end of the pressure measuring hose respectively connected with the bottom of the pressure measuring tube passes through the wall of the simulated cavity and is inserted into the aquifer. It can determine the hydrogeological parameters and calculate the water output of the aquifer, and clearly show the groundwater seepage state, aquifer and pumping well structure that cannot be observed in nature.

Description

Technical field: [0001] The invention is related to a submersible complete well pumping simulation device for studying groundwater movement laws. Background technique: [0002] When studying groundwater movement, mathematical methods are often used. The premise is to solve the aquifer or aquifer system under a series of generalization and restriction conditions. If these generalizations and restriction conditions can still reflect the main characteristics of the actual aquifer features, then a mathematically analytical solution is available. [0003] But for the actual aquifer, if its heterogeneity, anisotropy and complex boundary geometry do not allow too much generalization, then the mathematical method is difficult to apply, and the mathematical method is relatively abstract, making it difficult for beginners to understand . Therefore, the simulation method is used to study the law of groundwater movement under complex conditions. Among them, physical simulation is a c...

Problems solved by technology

In recent years, because production units are busy completing their own production tasks, it is difficult to accept college teachers and students for scientific research and on-site teaching practice, and the field pumping test costs a lot, so it is necessary to strengthen scientific research and practical teaching in the laboratory to make up for the Insufficiency of Field Test and Practice
