Abstract

Rancang bangun mesin turbin gas dimulai dengan mengidentifikasi beberapa komponen yang dibutuhkan dalam membangun sebuah mesin turbin gas. Turbocharger yang terdiri dari kompresor dan turbin sebagai penyusun utama komponen ini diambil untuk dijadikan Kompresor dan turbin mesin turbin gas yang juga merupakan unsur utama dalam sebuah mesin turbin gas. Agar sebuah mesin turbin gas dapat beroperasi maka perlu dirancang beberapa system pendukung seperti Oil System, Fuel System, Ignation System, Combustion Chamber dan beberapa system yang lain. Pada perancangan ini, penulis mendapat bagian dalam perancangan Sistem pelumas (Oil System) dimana tantangan yang dihadapi adalah mendapatkan jenis oil yang tepat untuk mesin turbin gas yang akan dibangun. Adapun rumusan masalah dalam perancangan system pelumas ini antara lain bagaimana menentukan viskositas pelumas yang digunakan, menghitung critical pressure bearing, menghitung jumlah pelumas yang digunakan, menghitung head pompa dan menghitung kapasitas reservoir yang digunakan. Output akhir yang dihasilkan dari perancangan ini adalah suplai oli yang mampu untuk melumasi shaft bearing pada turbocharger sehingga tidak terjadi overheating yang menyebabkan keausan serta metal to metal contact. Dari hasil perhitungan, didapatkan tekanan oli sebesar 37 psi yang diperlukan untuk melumasi shaft bearing pada turbocharger. Dan dihasilkan pembakaran yang continuous.

Abstract

Manufacturing of gas turbine engine was started by identification of some components and systems involve in building the gas turbine engine. A turbocharger which consist of turbine and compressor as the main part was taken to make a turbine and compressor in Gas turbine engine. Those component is also the essential part of the machine. To operate the gas turbine engine, it is important to design some system such as Oil system, fuel System, Ignition System, combustion chamber, and others. In this design project the writer obtains the task to design the oil system that fit and suitable for this type of gas turbine engine. Any issue related to this design such as how to decide the viscosity of the oil, calculate critical pressure of bearing, calculate mass of the oil fluid, head pressure of the pump and reservoir capacity. The final outcome of this design is correct supply of the oil flow which is used to lubricate shaft bearing in gas turbine engine. This system also prevent the machine from over heating that can degrade components of the engine due to metal to metal contact. From the final calculation found 37 psi oil pressure is needed to lubricate shaft bearing and can maintain the continuous operation of the engine.
