In this report, the torque losses using the calculating equation of power sprayer performance are analyzed, and the mechanical efficiency of power sprayer in a designing process are predicted by these calculating equations.
We were considered with a algorism to obtain the optimum values of plunger diameter and stroke giving a maximum mechanical efficiency in power sprayer.
Its algorism was programed by FORTRAN, and the designed calculations giving a discharge flow and a rotational speed of power sprayer were done by digital computer TOSBAC-3400/41.
The following results obtained.
(1) The torque loss was occured by the friction, in part of plunger seal, was fairly large value.
(2) The optimum values of plunger diameter and stroke calculated by this program were agreed with the these values in power sprayer supplied the previous experiment.
(3) If these were of the same contact width in part of plunger seal, a combination value of plunger diameter and stroke having the smaller stroke was shown the smaller torque loss.
