Maintenance tips and cleaning points for generators
Generators are very important for modern life. In modern life, the modern use of electrical energy requires generator conversion to be used. After a long time of use, generator cleaning is also very important. Then everyone knows the maintenance of generators. What are the methods? What are the cleaning elements? Let's learn more about the maintenance skills and cleaning points of the generator.
Maintenance of generator sets
1. Oxidative. The generator is oxidized for a certain period of time at a certain temperature, and then the acid value, viscosity change and formation of precipitates of the oil are measured. All lubricating oils have different auto-oxidation tendencies depending on their chemical composition and external conditions. Oxidation occurs with the use process, so some aldehydes, ketones, acids and gums, asphaltenes and other substances are gradually formed. The oxidizing property is the performance that inhibits the formation of the substances that are not conducive to the use of oils.
2. Thermal. Some high-quality anti-wear hydraulic oil, compressor oil, etc. have proposed thermal requirements. The thermal properties of oil products mainly depend on the composition of the base oil. Many additives with low decomposition temperature often have an adverse effect on the oil properties. Antioxidants cannot significantly improve the thermal properties of oil products.
3. Oily and extreme pressure. Therefore, it plays the role of resistance to high load and friction and wear, and extreme pressure is that the polar substance of the lubricating oil on the metal surface of the friction part is decomposed by friction chemistry under high temperature and high load, and the friction chemistry with the surface metal occurs. It reacts to form a soft or plastic film with extreme low melting point and extreme pressure film, so as to play the role of impact resistance, high load and high temperature lubrication.
4. Corrosion and rust. The corrosion test for generator maintenance is generally to put the copper bar in oil, leave it at 100 ℃ for 3 hours, and then observe the change of copper; while the rust test is under the action of water and water vapor, the steel surface will rust. The rustiness is to add 30 ml of distilled water or artificial seawater to 300 ml of test oil, and then place the steel rod therein, stir at 54 ° C for 24 hours, and then observe whether the steel rod is rusty. Oil products should have anti-corrosion and anti-corrosion effects. In the industrial lubricant standard, these two items are usually required items.
Generator maintenance impurity removal
1. Generator repair These colloidal substances can be divided into sol-soluble and non-sol-sol based on the solubility of gasoline.
2. The non-solaceous substance is also known as sediment. When it is added to the fuel tank of the car with fuel, it will adhere to the fuel filter, block the filter medium, reduce the amount of oil supplied, make the amount of fuel insufficient, and atomize the fuel. Poor, causing the combustible mixture to become lean, and the engine's power and economy are reduced.
3. To eliminate these problems, you must remove the carbon deposits and the gum in gasoline. However, the method commonly used in many auto repair plants is to disassemble the engine and then clean it. This method is not only time-consuming, labor-intensive, but also The effect is not ideal.
4. It is even more difficult to remove the glue in the fuel tank and the fuel tank, and it is not suitable for the engines of today's cars, because today's automobile engines are assembled under strict process requirements in a constant temperature, dust-free, and ultra-quiet environment. After reassembly, its power and sealing performance cannot be compared with the original performance.
5. Now you don't have to worry about this because you only need to add a certain amount of fuel system cleaning and protecting agent in the fuel tank. Repairing the generator can solve various problems caused by carbon deposits. The fuel system cleaning and protecting agent has gasoline. Products that are common with diesel, specially designed for EFI vehicles, and special for gasoline engines, can automatically remove hard carbon deposits during the driving of the car, so that the performance of the engine returns to normal and no longer suffers from disintegration. Can completely remove carbon deposits and enjoy driving pleasure.
The above is a brief introduction about the maintenance skills and cleaning points of the generator. I hope this knowledge will help you!
