Abstract

Liquid-gas ejector is an energy conversion device capable of flowing air fluid by utilizing water fluid based on the pressure difference between the two fluids without using moving parts. This study aims to determine the effect of changing nozzle spacing on the two-phase flow on the performance of the liquid-gas ejector. The method used is to carry out an experiment whose stages include: determination of nozzle spacing parameters, primary flow rate, and secondary flow rate. Then perform tests on the liquid-gas ejector installation and collect data. The test was carried out by alternately varying the nozzle spacing, primary flow rate, and secondary flow rate. Then analyze the data that has been collected to get the efficiency or performance of the liquid-gas ejector from changes in nozzle spacing. Increasing the nozzle spacing causes a decrease in the efficiency of the liquid gas ejector. The efficiency of the liquid gas ejector with nozzle spacing 5, 10, 15, 20, and 25 mm is 17.17%, 13.49%, 12.06%, 11.41, respectively. %, and 10.47%.Keywords: Nozzle spacing, flow, two phases, performance, liquid-gas ejector.

Abstract

The Pneumatic System is a power transfer system utilizing compressed air as an intermediate medium. In conventional operation it is operated fully pneumatically or in combination with electricity (electropneumatic). In recent years it can be combined and controlled with a programmable logic controller (PLC). The operation of the pneumatic system with the PLC control system is carried out by desaign a program with a program language, one of which is the Ladder Diagram accompanied by I/O addressing, then the result design program must be transferred to the PLC as the controller of the pneumatic system in this case the controller. robot hand. This study aims to obtain a pneumatic robot hand circuit and a series of ladder diagram programs to control the PLC system in the robot's hand. The results of this research can be used as a reference in designing a pneumatic system with PLC control in the future.
