Maintenance methods of diesel engine fuel injection pump

(1) Use good diesel oil and filters to ensure that the diesel oil entering the fuel injection pump is highly clean
Generally speaking, the filtration requirements of diesel engines for diesel oil are much higher than those of gasoline engines for gasoline. When using diesel engines, you must choose diesel oil that meets the requirements, and it must be precipitated for at least 48 hours. Strengthen the cleaning and maintenance of the diesel filter, clean or replace the filter element in time; clean the diesel tank in time according to the working environment conditions, and completely remove the sludge and water at the bottom of the fuel tank. Severe corrosion or wear of the valve coupling and transmission parts.
(2) Always check whether the oil quantity and quality in the oil pool of the fuel injection pump meet the requirements
Before starting the diesel engine, the quantity and quality of the oil in the fuel injection pump should be checked (except for the fuel injection pump that is forced to lubricate by the engine), to ensure that the quantity of oil is sufficient and the quality is good. If the engine oil deteriorates due to mixing with water or diesel oil, it will cause early wear of the plunger and the oil outlet valve assembly, resulting in insufficient power of the diesel engine and difficulty in starting. In severe cases, it will cause corrosion and corrosion of the plunger and the oil outlet valve assembly. Internal leakage of the oil pump, poor operation of the oil outlet valve, wear of the tappet and casing of the oil delivery pump, and damage to the sealing ring will cause diesel oil to leak into the oil pool and dilute the engine oil, so it should be replaced in time according to the quality of the engine oil. When replacing, the oil pool should be thoroughly cleaned to remove impurities such as sludge at the bottom of the oil pool, otherwise the oil will deteriorate after a short period of use. The amount of engine oil should not be too much or too little. Too much oil in the governor will easily cause the diesel engine to "speed". In addition, when the diesel engine is not used for a long time, be sure to check whether there are water, diesel and other impurities in the oil in the oil pump oil pool, and replace it immediately if there is any, otherwise, due to long-term storage, the water will easily damage the plunger and the oil outlet valve. Even parts are corroded, stuck and scrapped.
