Abstract

To meet the electricity needs at night and the production of agricultural products in Kp. Mulyasari was designed and built a Micro Hydro Power Plant (PLTMH) Turbine which can produce power up to 2,500 Watt. This machine is designed to be easy to install, easy to operate, inexpensive to maintain. The selected turbine type is a Cross-Flow air turbine for a low head. Turbines operate at impulse pressure, where the potential energy of water is converted into kinetic energy through the nozzles to push the turbine's front blades. In the design of this turbine, it is designed, so that it has a long life span, low investment value, minimal maintenance costs, easy installation costs, and is driven by water, thereby conserving natural resources. The turbine is designed based on data from field survey results in Kp. Mulyasari, with results; Head (H) = 1.85 m; Water discharge (Q) = 0.2 m3 / s; Turbine rotation (planned) (n) = 214 rpm; Turbine efficiency (plan) (ηt) = 68%; Density of water (ρ) = 997.8 kg / m3. From the calculation results, obtained the Cross-Flow turbine design specifications as follows: High waterfall (H) = 1.85 m; Water discharge (Q) = 0.2 m3 / s; Turbine efficiency (plan) (ηt) = 68%; Power (N) = 2,497 kW; Rotation (n) = 214 rpm; Specific speed (ns) = 770,4138831 rpm; Road blade diameter (DL) = 0.40 m; Naaf diameter (Dn) = 0.035 m; Steering blade width (B) = 0.032 m; Number of road blades = 26 pieces.

Abstract

Water pump adalah pompa sentrifugal yang tugasnya mensirkulasikan air ke dalam sistem pendingin pada engine.Dari data problem komponen di tahun 2020 pada Workshop Plant Rebuild Center PT X,sering terjadi kebocoran seal air pada water pump engine type SAA6D170E-5 sebanyak tujuh kali. Oleh karena itu,tujuan penelitian ini adalah untuk mencari penyebab terjadinya kebocoran pada seal air di water pump untuk dilakukan perbaikan agar tidak terjadi kerusakan lagi pada komponen water pump. Dengan menggunakan metode alir,dapat menganalisis kerusakan water pump. Dari hasil analisis tersebut untuk mendapatkan beberapa temuan penyebab sering terjadinya kebocoran pada water seal yaitu adanya partikel debu yang masuk ke permukaan water seal,pemasangan bearing shaft yang belum standar,dan metode pemasangan water seal yang salah. Setelah itu dilakukan perbaikan proses assembly,dari penambahan hose transparan di lubang indikator,mengganti alat pemasangan bearing dan mengganti pelumas water seal dari oil ke sabun.Setelah dilakukan perbaikan,dapat di evaluasi kualitas dari komponen water pump dari data problem engine type SAA6D170E-5 di bulan mei sampai bulan September tahun 2021 bahwa komponen water pump tidak terjadi kerusakan.Sehingga dengan perbaikan proses assembly komponen water pump pada engine type SAA6D170E-5 dan di tuangkan pada prosedur INK (Intruksi Kerja) yang sesuai dengan shopmanual yang terbaru menjadikan hasil kinerja dari komponen water pump menjadi baik dan berkualitas sangat tinggi

Abstract

When the generator set is operating it is often overheated, the load does not match the capacity of the power expended. An early indication of a high cooling system temperature and this affects the reliability of the generator set that is operating. Overheating can be the initial cause of damage to engine components and can cause fatalities. To find out the root cause of damage to overheating in the cooling system must be analyzed. The damage analysis method is to know the generator set operating system and ensure the loading conditions and temperature measurements on the radiator. The main cause of overheating is lack of radiator water, where the lack of water is caused by leakage on the radiator cap, radiator core, dead-end radiator tube, radiator blocking, water leakage from the water pump, leakage from the pipe or radiator hose. To minimize damage to the steps that must be done is, to recondition the radiator in case of damage to the core, radiator tube, and if there is a water leak from the water pump then what must be done is repair or replacement of the water pump. While damage to the pipe or hose must be replaced and if the radiator water is contaminated with oil, flushing of the radiator water must be carried out, doing regular cleaning of the radiator core. From the analysis and some cooling system maintenance actions, to minimize the occurrence of overheating periodic maintenance must be done
