Rancang Bangun Simulator Elektro-pneumatik Berbasis Relay Dengan Dua Aktuator

Abstract

DESIGN OF ELECTRONIC-PNEUMATIK SIMULATOR BASED ON RELAY WITH TWO ACTUATORS The purpose of this final project is to design, assemble, and test the electro-pneumatik simulator as an educational trainer. The designed simulator consists of 2 (two) actuators which can be simulated sequence of actuators. Size of component, component type, and size of a whole simulator was designed on the basis of financing and aesthetics. Simulator consists of 2 (two) systems, namely pneumatik system and electronic system. Components on a pneumatik system were compressors, F. R. L. s (F.R.L), distributor, 5/2-solenoid valve, throttle valve and double acting cylinder as an actuator. The electronic system consists of 220V AC / 24V DC transformator, Push Button, timer, counter, relay, limit switch, and solenoid on pneumatik valve. Electro-pneumatik components were attached on a vertical melamine board. Simulator testing is done by functional test of each component and Electro-pneumatik circuit test. Supporting instruments used for the functional test were the stopwatch and the dynamometer. The functional test of the compressor was performed to know the accumulator charging flow rate in the parameters of free air delivery (FAD) in order to indicates that the component functions according to its characteristics. The functional test of force generated by the cylinder was measured by a dynamometer. The functional test of each component shows that the component function fit to its characteristics. The rate of air filling to the accumulator was 70.05 Nm3/minute and the force that was generated by the cylinder at pressure 6 kg /cm 2 was 14.73 kg. Functional test of electronic components was done by giving a 24V DC current on each component and observed its active status (ON / OFF). Electro-pneumatik circuit test was done by performing an electro-pneumatik circuit to fit a determined sequence. Keywords: Electronic System, Pneumatic System, Electro-pneumatic System
