Description

Smart washing system{A SMART WASHING SYSTEM}

The present invention relates to a smart cleaning system for many parts such as engines and transmissions of vehicles, aircraft, ships, and agricultural machinery.

In general, engines or transmissions of vehicles, aircraft, ships, agricultural machinery, etc. are assembled by assembling many parts. To improve the performance and improve the quality of the assembled finished product, foreign substances must be removed from the many individual parts assembled in the engine or transmission and thoroughly managed. It is very important to do.

In order to remove carbon from parts where carbon has been deposited, the carbon attachment surface is heat treated (gas torch, etc.), then the carbon is first removed using a metal brush, and then soaked in a water bath containing an acidic cleaning solution for a certain period of time and then washed with a soft brush. Then, secondary carbon removal work is performed using a blade, or removal work is performed using an airbrush or high-pressure water.

In particular, in order to clean parts (scavenging device, cylinder head, etc.) on which high-viscosity tar, oil, and carbon are mixed and deposited, remove as much large foreign substances attached to the surface as possible by hand. After the soaking process is performed in a temperature water bath (acidic solution, solvent, etc.), the surface of the soaked product is cleaned by secondary manual work using an airbrush, high-pressure water, etc.

Recently, parts that have been initially washed manually are cleaned using an automatic washing machine with a structure similar to a dishwasher. In other words, high-pressure water is sprayed from a rotating nozzle attached to a small water tank and used to clean parts.

However, due to the large fluctuation in the cleaning rate depending on the complexity of the part structure, not only does the follow-up work for the operator increase, but it also has the disadvantage of making it difficult to achieve a 100% cleaning rate.
