一定量の供給がなされなければならない。By the way, in order to clean the cylinder of a printing machine, it is necessary to always supply a required fixed amount of cleaning liquid, and it is necessary to be able to adjust the amount of cleaning liquid as needed. This is because if the amount of the cleaning liquid is small, the cleaning is not performed sufficiently, and if it is too large, the cylinder of the printing machine and other precision parts are unnecessarily wetted, which adversely affects the printing accuracy. Further, since it is necessary to adjust the amount of cleaning liquid depending on the degree of contamination, the amount of cleaning liquid must be accurately supplied at a constant amount.
