[Abstract]:Household cleaning machines are more and more widely used in home, generally used in yard cleaning and car cleaning, people enjoy the fun of life after work. Based on the electric high-pressure cleaning machine for household cold water, this subject has the advantages of compact structure, simple operation, flexible and light use, moderate price, and suitable for the life of the mass family. First of all, this paper describes the classification of household cleaning machines; Secondly, the working principle and washing mechanism of the cleaning machine are discussed and analyzed. Thirdly, the types of driving device and piston pump are briefly introduced, and the working principle and structure design of piston pump are introduced, and the main parameters of the mathematical model of piston pump are analyzed and calculated. The mechanical analysis and dimension check of the parts are also carried out. (this paper mainly describes the motor driven oblique disc piston pump; Then, the structure and basic parameters of the jet, the formation of the jet in the spray gun, the selection of the assembly of the gun rod based on the theory of the jet, the problems to be paid attention to with water as the driving medium are studied. The most suitable nozzle caliber is determined after experimental study and analysis. Finally, through the research on the application of Venturi tube in household cleaning machine, the structure of Venturi tube runner is optimized, and the engineering prototype is made to verify the experiment. The results show that the optimization scheme can reduce the pressure loss of Venturi tube and improve the overall performance of the pump.
