Oil inspection of domestic diesel generator sets
- 2019-03-05-

    Domestic diesel generator sets operate in the absence of oil, because Lack of oil causes abnormal wear or burning. Therefore, before starting and during the operation, it should be ensured that there is enough oil to avoid pulling the cylinder and burning the tile due to lack of oil. Do not slam the throttle after starting. If the throttle is slammed, the generator speed rises sharply, which will cause some conflicting surfaces on the aircraft to wear heavily due to dry friction. In addition, when the accelerator is subjected to an impact, the acceptance of the piston, the connecting rod, and the crankshaft varies greatly, the impact is severe, and the parts are easily damaged.

    Check the fuel quantity of the domestic diesel generator set, observe the fuel storage capacity of the fuel tank, add enough fuel as needed; check the oil level in the generator oil pan, the oil level should reach the oil dipstick On the above indication, when the oil quantity is insufficient, the specified amount increases the oil level of the diesel fuel injection pump governor, and the oil level should reach the engraved line mark on the oil scale. When it is insufficient, it should be added.

    Check the three leakage (water, oil, gas) of domestic diesel generator sets. Eliminate oil leakage and water leakage on sealing surfaces such as oil and water pipe joints; eliminate air leakage from intake and exhaust pipes, cylinder head gaskets and turbochargers; check the installation of accessories, including installation stability and anchors for each accessory Reliability of connection to work machines.

    Check all instruments of domestic diesel generator sets. Observe whether the reading is normal, otherwise it should be repaired or replaced in time; check the transmission connection of the fuel injection pump. Regardless of whether the connecting screw is loose or not, the spray advance angle should be adjusted again, and the connecting screws should be tightened to clean the appearance of the generator and auxiliary equipment. Wipe the oil, water, dust on the surface of the fuselage, turbocharger, cylinder head cover, air filter, etc. with a dry cloth or dry cloth soaked in diesel oil, and wipe or blow off the live generator, radiator, fan with compressed air. Dust on the surface.

    Inorganic fouling (such as road dust or wear products) mixed with domestic diesel generator oil will accelerate the wear of parts with multiple abrasive actions. If the amount of abrasive particles entering the cylinder with the lubricating oil can make the wear become the main form of wear, the axial wear characteristics of the cylinder will be changed, and the quality determines the wear resistance and the nature of the use of the part, thus determining the durability of the part.
