摘要
利用杠杆原理,把水的浮力、永磁铁的磁力及惯性力进行合理的调配,克服抽采系统的高负压,使放水器在60kPa以上的负压状态下完成自动放水。
The study uses the level principle to deploy the buoyancy, magnetic force of permanent magnet and inertia force rationally. The high negative pressure of drainage and extraction system is overcome and the drainage device could drain water automatically under the state of negative pressure （〉60 kPa）.
