Abstract

ABSTRACT Heat Exchanger is equipment used to carry out the process of exchanging heat between two fluids, either liquid (hot or cold) or gas, where these fluids have different temperatures. Singkarak hydropower plant also uses a plate type heat exchanger with the code M10-BFG in operation. Serves to exchange heat in the oil used in the upper oil pot, which functions as a cooler and lubricant for the upper bearing and thrust bearing. Seeing the function of the upper and thrust bearings, which are two important bearings in the unit. A good maintenance process is needed on the plate heat exchanger to maintain the condition of the oil at working temperature, which is at 45-55 0C. Through this research, the authors analyzed the performance of the M10-BFG plate heat exchanger with the parameters of the actual heat transfer coefficient and monthly temperature trends. After doing research with quantitative methods through data collection and data processing, it was found that unit 4 has the highest actual heat transfer coefficient of 875.666-900.574 W, but has the shortest usage time, for 42 days based on the existing trending temperature. This is because in unit 4 the oil flow (870-900 l/minute) is below standard, and the size of the heat exchanger plate (55 cm) has shrunk far from the initial value (63 cm). So it is necessary to carry out corrective maintenance on unit 4. Meanwhile, the lowest actual heat transfer coefficient is found in unit 1 with a value of 706.797-770.027 W and the longest plate heat exchanger usage time is in unit 3, with an estimated 121 days before reaching the 55 0C alarm.

Abstract

Turbine Bearing is a piece of equipment used to keep the shaft rotating about its axis or to keep a linearly moving component on track. The operation at PLTA Maninjau also makes use of a Turbine Bearing with a Journal Bearing type. The turbine bearing of the Maninjau hydropower plant experienced an abnormality, with the bearing temperature rising from 60°C to 80°C. Using the fishbone diagram method and failure mode and effects analysis, the authors conducted a root cause analysis of the causes of the increase in turbine bearing temperature in this study (FMEA). The cause of the increase in. The cause of the increase in the temperature of the turbine bearing unit 2 of the Maninjau Hydropower Plant was found to be a misalignment caused by a small bearing clearance of 0.2 mm, which should have been 0.4 mm according to the design value, after conducting research using the observation method through data collection and data processing. And reduced cooling water effectiveness from 18.41% to 1.15%. As a result, corrective maintenance on Maninjau Hydropower Unit 2 is required.

Abstract

In a new Honda Jazz car, there is a rotten smell coming from inside the AC cabin, the temperature is not cold and causes the windshield to fog up. The purpose of the research is to find out the causes of damage to the AC system and appropriate maintenance actions. The method used is primary data, namely by direct inspection it is known that the refrigerant parameters are low on the pressure gauge manifold device on both sides LO 0.6–0.8 kg/cm2 and HI 8–9 kg/cm2. Damage to the capillary pipe is leaking. The action taken is to replace the capillary tube components, so the temperature parameters become LO=1.5–2.0 kg/cm² and HI=14.5–15 kg/cm². Once the pressure on the compressor, LO=4–6 kg/cm² and LO=7–10 kg/cm². The temperature is hot in the vehicle cabin. After replacing the compressor Normal pressure LO=1.5–2.0 kg/cm² and HI=14.5–15 kg/cm². Unstable Condenser temperature, LO=15Psi. HI=300–350Psi. cleaning is carried out at the temperature parameters LO=25Psi and HI=150 Psi, normal conditions. The hot room temperature = 29.2ºC and the cleaning action is carried out, then the temperature becomes = 16.8ºC, the AC room temperature returns to normal.

Abstract

Motorcycles are vehicles that have quite high economic value when compared to other vehicles. Motorcycles are made up of several constituent components, one of which is the use of final gear. The purpose of this study was to determine the amount of torque and the ratio of torque produced from the final gear size 13,14,15 on the new 2013 vixion motor. From the data obtained, the maximum torque when using the final gear size 13 = 15.24 Nm at a speed of 7.05 rpm. 14 = 15.49 Nm at 7.33 rpm and 15 = 15.91 Nm at 6.83 rpm. While the difference in the ratio of torque produced by the final gear (standard) size 13 and size 14, the difference in value = 0.22 Nm, the final gear size 14 is larger, the difference in the torque ratio between size 14 and size 15, the difference in value = 0.35, is greater than 15 size 14, the difference in the torque ratio between size 15 and size 13 is the difference in value = 0.57 Nm, which is 15 greater than size 13

Abstract

Semen Padang Indarung IV unit has a screw compressor type compressor unit to produce high pressure air. In its operations, one of the Atlas Copco type compressor units often experiences over heating problems, namely the working temperature exceeds 1000 C. The method used is trouble shooting the compressor system, such as checking the lubricating oil, pressure, valves, working temperature and cooling system. , as well as overhaul maintenance actions if necessary. Based on the research results, it was found that the factors that cause overheating of the compressor are: Dirty air quality affects the condition of the air filter for air supply, limited space for placing the compressor causes the air supply to decrease, the oil filter has passed its useful life and is not suitable for use, and the oil cooler is clogged with scale, which hinders the oil cooling process. Based on this damage, recommendations for maintenance activities on the Atlas Copco Compressor are: maintaining air quality, periodically cleaning the tubes in the oil cooler, replacing the new oil filter according to compressor specifications, as well as comprehensive maintenance measures

Abstract

Compressor is one of the equipment on the ship in the process of smooth sailing for the purposes of starting the main engine and also functions to increase gas pressure, distribute air to other parts so that the process runs smoothly. MT Tanker Ship. Sea Serenity is a goods delivery ship. On this ship, the compressor is used to carry out maneuvers, namely the main air compressor which produces air pressure of 12 bar for 10 minutes, but it should only be 5 minutes, meaning the compressor performance is not optimal. The causes of decreased performance in the compressor are: Dirty/clogged air valve, wear of the piston ring/housing, non-functioning of the low pressure and high pressure suction valves. Recommendations for maintenance activities on the LSHC-50A air compressor are: Ensure air circulation to the compressor room is clean/free from dust or dirt, add an air filter, and maintain room temperature stability (providing air conditioning). Maintain the cleanliness of the blower, check the oil filter, replace damaged pistons, and replace new piston rings according to compressor spare parts every 6000 working hours
