Design of the Motor-less Fully Automatic Filter with Speed Variable

The motor-less Fully Automatic Filter is the most popular research type of filtration machine at domestic and abroad.This paper is concentrated on the work principles and structure characteristics of the Filter's driving system and a new motor-less fully Automatic Filter with speed variable has been developed. The experimental results demonstrate that its features are no interruption of downstream flow during flushing without electric motors and external power, water-saving, well interchangeability, easy assembly and disassembly, high automation,low cost, broad application prospects and a huge market potential.
