Research on a new type of squirt gun for cleaning

摘要

A new type of squirt gun, which is similar to a jet pump and can better induce formation of cavitating water jet, is presented. The scheme of design of this new squirt gun is discussed. An investigation of effect of different area ratio, length of throat pipe, standoff distance, nozzle type, and suction air amount on decontamination ability was made by experiments. This new squirt gun is experimentally compared with conventional one. Test data indicate that under the same operating condition the new type of squirt gun have the advantages of better decontamination ability, lower energy consumption and less water consuming over conventional one. The optimum operating parameters of this new device are put forward on the basis of test results.
