Oli Hydrolik Overheat_Error B@HANS_PC200-10M0_Bagaimana cara Pemeriksaannya agar tidak salah Analisa

Understanding Hydraulic Oil First, it's important to understand what hydraulic oil is. Hydraulic oil is a type of oil that has a viscosity and classification similar to engine oil. The difference is that hydraulic oil viscosity levels are not specified by SAR or API Service codes. To better understand hydraulic oil, it's helpful to understand the properties of this type of oil, including: 1. Hydraulic oil is fluid, meaning it flows easily. 2. It is incompressible, meaning it cannot be compressed. 3. It has stable physical and chemical properties. 4. It has lubricating properties. 5. It prevents rust by protecting engine parts. 6. It can separate impurities. Damage to hydraulic oil can be caused by two main factors: deterioration and contamination. Deterioration is damage caused by factors within the oil, while contamination is damage caused by factors outside the oil. You should never ignore or trivialize oil problems, as when they occur, the engine can experience problems, as the oil has a significant impact on various components within the engine. The various properties of hydraulic oil mentioned above can only be utilized optimally if the oil is free from problems, including hot hydraulic oil. Causes of Hot Hydraulic Oil Several factors can cause hot hydraulic oil, including: 1. Coolant Circulation System One cause of hot hydraulic oil is a malfunctioning coolant circulation system. Blockages and dirty channels result in decreased cooling efficiency and higher oil temperatures. 2. Hydraulic System Working Pressure Hydraulic oil heats up when the adjusted working pressure of the hydraulic system is much higher than the actual requirement. 3. Worn components Such as pump gears, pump pistons, motor cylinders, valve plates, bores, and plungers. This can lead to increased internal leakage and cause hot hydraulic oil. 4. High Load Use Prolonged high load use and excessively high ambient temperatures can also cause hot hydraulic oil. 5. Air Circulation The hydraulic system may not have sufficient flow to dissipate heat if the hydraulic fuel tank is too small, causing the oil temperature to rise. 6. Hydraulic Oil Grade Differences in quality, viscosity, and hydraulic oil grade can cause the hydraulic oil viscosity index to be too low or too high. 7. Other Factors Various factors such as serious pollution, poor construction environments, and the ingress of contaminated hydraulic oil into the gaps of pumps, motors, and valves can increase friction, wear, and leaks, leading to high oil temperatures. 8. Filter Plug Hot hydraulic oil can also be caused by a filter plug, which creates oil resistance and increases energy consumption. 9. Electrical System It could also be a problem with the electrical system, such as the hydraulic oil temperature sensor, wiring, or controller. How to Maintain Hydraulic Oil To prevent hydraulic oil from overheating and ensure long-term use, there are several proper maintenance methods you can follow, including: 1. Try to store the hydraulic oil drum under a roof. 2. Always clean the top of the drum before opening it to prevent dirt from entering the oil when the drum is opened. 3. Make sure you use a clean jerry can or container and hose. 4. Before pouring oil into the reservoir, filter the oil first. 5. Protect the oil from contamination that can be caused by condensation. 6. Ensure the assembly parts are securely attached and the filter system is in good condition to prevent oil contamination. 7. Schedule an oil change before total damage occurs. #komatsu #HYDOilOverheat #pc200
