Abstract

PLTD (Diesel Engine Power Plant) is one generator used by several companies, especially electricity providers. It’s just that PLTD requires a large enough cost to produce electrical energy. Therefore it is necessary to make efforts to reduce operational costs, one of which is by making an alternative to charging the accumulator on the diesel engine. The alternatif is a prototype solar cell that can charge the 200 Ah 12 Volt accumulator so that the accumulator can be used for the starting process diesel engine (PLTD). So, at this writing the author tries to make an experimental study of the use of solar cells as an alternative to charging a 200 Ah 12 Volt accumulator which in this experimental study proceduces a 2 x 80 Wp mobile solar cell prototype that can be used for charging the accumulator of PLTD machines. In addition, from this experimental study, the results of accumulator charging of 1,444.92 Wh are sufficient to be used for the dynamo starter process on diesel diesel engines and the annual savings value is obtained.

Abstract

Pellet machine is a machine used to print feed in the form of pellets. In this machine, if it operates, it can experience excessive vibration and the force acting on the machine is close to its natural frequency and can cause damage, so it needs to be reduced. In this study, the objective of this research is to model and simulate vibrations in the gearbox and grinder to determine the results of the displacement and acceleration vibration responses on the pellet machine. In this study, an electric motor is used as a source of rotation and an input clutch as a connection between the shaft of the electric motor and the gearbox as a transmission to reduce the speed of the electric motor, where the rotation produced by the electric motor contains vibrations, the output coupling is the connecting shaft between the gearbox shaft and the shaft grinder and miller as a tool used to print pellets. From the existing physical form, mathematical equations and simulation blocks are constructed. In this research, it is found that the vibration response generated from the gearbox and grinder can be modeled with the x and z axes as the center of the system. The higher the vibration response, the higher the given frequency, the greater the amplitude and rms of the displacement and acceleration responses in each part, namely the motor, clutch in, gearbox gearbox, coupling out, and grinder will be greater. The result of displacement vibration response yields an rms of 1.956. The worm gear in the gearbox produces a displacement vibration of 1.0585 m and an acceleration of 6.8485 m/s2. The mill produces a displacement vibration of 1.0891 m and an acceleration of 5.1095 m/s2.
