Diseño y simulación del sistema automático de distribución de diésel tipo II desde el tanque principal hasta los tanques secundarios y de almacenamiento diario de 1850 y 380 galones respectivamente

Abstract

The present degree thesis was involved at the Nueva Aurora Gynecological-Obstetric Hospital "Luz Elena Arismendi" (HGONA), to serve as much as possible of the lost time of the personnel at the facility, through automation. The main objective is to design an optimal route to transport diesel from the main tank of 11800 gallons to the secondary tanks that provide fuel to the daily tanks of 1850 and 380 gallons respectively, so that the different areas have an excellent performance, thus optimizing the operation of the hospital. Using a study and sizing of the system, the type of accessories required will be determined. According to the results obtained, a VOGT pump n=1750 rpm, model NE 620, will be used to distribute the fuel through a black pipe with a diameter of 2 inches. Different accessories such as elbows, valves, unions, and universal conical fittings will be used, and a Kobold NKP-401 plastic level sensor will be used to measure the liquid in each tank. A Danfoss EV220B 2" EPDM 032U7150 solenoid valve will be used in the system, which will be controlled by a LOGO! programmable logic module with the expansion of digital inputs and outputs LOGO! DM8 230R, to make the electrical connections from the PLC to the valves and sensors. It will also be used mini-din 5-pin straight communication cable for the sensors and control cable 3 cond. 1.0 mm/ 18 AWG black conductor for the solenoid valve. The present project will have a cost of $10,276.24, thanks to that the requirement was from the hospital, it isn’t necessary to have an economic feasibility analysis of the project, due to a budget destined for a possible implementation of the diesel distribution system.
