Development of Mixed System Part-cleaning Machine

Abstract

The objectives of this research were to: 1) construct a mixed system part-cleaning machine, 2) find the efficiency of the mixed system part-cleaning machine, and 3) study the satisfaction of using the mixed system part-cleaning machine. The sample group included 5 service-center technicians selected by purposive sampling technique from Chairachakarn Chumphon Company. The research was conducted in the academic year 2022. The tool used in the research was a mixed system part-cleaning machine, assessment forms and satisfaction questionnaires analyzed by mean and standard deviation.

The research results showed that: 1) the mixed system part-cleaning machine consisted of a supporting sieve of 58 cm. wide and 85 cm. long. The conical basin to support the filtered oil for separating the impurities was 34 cm. wide and 85 cm. long. The lid for opening and closing has a diameter of 58 cm. The compartment for cleaning, blowing, and holding the parts has a diameter of 14 cm. with the glass window  of 24 cm. wide and 22 cm. long for looking through while washing or blowing air equipped with an oil mist fan. There is an oil circulation system consisting of a filter and a fuel pump with a 12 V solenoid valve system. To control the use of water or oil, the system works by using oil pressure to wash the parts with a filter system that can be repeated 9 cycles at one loop. There is also a blow-drying system after washing the parts. The machine was evaluated for the quality by the experts with the result on the design at the highest level. 2) The mixed system part-cleaning machine takes less time on the average than the traditional part-cleaning machine. And 3)the  users’ satisfaction level was very high.
