The use of agricultural machinery and diesel engine lubrication system maintenance

2020 - the use of agricultural machinery and diesel engine lubrication system maintenance 09 - 28 lubrication system maintenance requirements to choose qualified lubricating oil. Must be according to the instruction of filling oil, especially for supercharged diesel engine should be paid attention to more. Within the oil filling does not allow mixed with water, dust and impurities, etc. Regularly check the crankcase oil level height, and keep the oil level height but high, but also low. The new engine should add slightly more oil, after running, check the oil level height, parking has put more, less is more. Add the oil must be the same with the original use of the oil brand level. The oil when the oil level is lower than the lower limit markers, are not allowed to start the engine; Below the intermediate tag, not allowed to drive. Check the oil level, at the same time with the hand twist rub oil the oil on the foot, examine its viscosity, and presence of gasoline or blisters. Water cut of oil it is gray. Found oil metamorphism discoloration, sediment excessive oil pan or oil mixed with water, fuel, should be replaced in a timely manner. Before starting the engine, the crankshaft using hand rotation number of circle, and then start the engine, so that the ministries have been fully lubrication; Before the start of winter, lubricating oil should be preheated heating. In operation, often should pay attention to moderate oil pressure, oil pressure alarm indicator, adverse phenomenon should stop in time to check, and troubleshooting. Daily parking should rotate the oil strainer handle after 2 ~ 3 turn and listen to find running inertia of the rotor of the centrifugal oil filter 'buzzing' sound, if they do not conform to the requirements, should be in time for maintenance. Often do crankcase ventilation device maintenance, repair work, ensure oil well in the oil sump. Took advantage of the maintenance and overhaul to cleaning of lubricating oil and lubricating system, and replace the oil filter or filter according to the requirements of regulations. Should strictly implement the system of winter and summer seasonal oil change alternately. As stipulated in the model of the engine oil change cycle, combined with the oil quality of oil change in time. When replacing oil of different grades, different manufacturers, must clean the lubricating system, in case of different type of oil deterioration caused by each other. Oil lubrication system maintenance notice before the car check, provisions must keep the height of oil level and oil without deterioration. Attention should be paid to the oil in the operation of the table of reading, keep the hydraulic oil temperature is normal. Oil pressure too low, can't use the method of adjusting oil pump pressure limiting valve to solve, must find out excess oil in oil duct leakage ( Oil pressure build up) Why, if necessary, check the relevant parts ( Such as the axis and tile) Wear and tear, repair, respectively. Lubrication system maintenance daily to check the oil reserves and quality and supply of lubricating oil. Pay attention to the instructions of hydraulic work. Cycle timely replacement of lubricating oil in accordance with the relevant provisions, oil change, should be under the engine hot, put all the old oil, with special cleaning equipment, cleaning, lubricating oil way after, again as stipulated in the original factory capacity and brand new lubricating oil filling. According to the technical level of maintenance for maintenance. Timely check centrifugal oil filter operation is normal; To clean strainer; The coarse filter (for an oil change Filter paper) 。 When necessary, remove the fine filter shell cleaning rotor cover inner surface sediments, and cleaning of rotor, keep clear of the oil nozzle; After the assembly, the rotor rotation should be flexible, no leakage phenomenon; Daily check and add lubricating oil. In accordance with the provisions, oil change, filling oil shall comply with the provisions of the brand specifications; Remove oil filter and oil in the dirt; To prevent engine ventilation pipe plug. Before the car every day, want to check the engine oil surface and oil. Oil level cannot under the lack of oil below the mark, but not in excess of the prescribed scope. Oil drain shall be carried out in hot engine ( For from the crankcase from dirt and oil) ； After the oil is put, can add half of the oil, turn the crankshaft 1 ~ 2 minutes, then the oil out, and then filling the new oil; Start the engine, rotating 3 ~ 5 minutes at low speed, parked, and then check the oil and add to the amount of oil level. When cleaning, should use a used engine oil, unavailability of thin oil washing, more do not use kerosene. When carries on the repair and maintenance, must remove the crankcase, refitted after dry cleaning, filter should be cleaned at the same time set filter, oil filter and other components. In use that the oil level of oil increases, should immediately check the reason and ruled out. The oil level of oil rise, usually because the engine temperature is too low, bad gas atomization combustion, condenses into the oil pan after mixed with oil; After the engine oil pan and clean from oil filling mouth filling grade of lubricating oil, until the oil on the plane to the oil scale line. Lubricating oil filling cannot too little or too much, more can't let the dust into the mouth filling, in order to avoid clogging oil. Cleaning of engine lubricating system. Under the engine thermal state, the crankcase oil and coarse, fine filter all is put on oil. From oil mouth filling equivalent standard capacity 60% ~ 80% of cleaning oil ( Or the filter of high quality light diesel oil) And then the engine idle speed running 2 ~ 3 minutes ( Or use the hand crank rocking-turn crankshaft 3 ~ 5 minutes) 。 After cleaning, put clean oil, remove the coarse, fine filter core, with a touch of wash oil cotton wipe cleaner lumen. The coarse filter cartridge assembly on wash oil with hair brush net, and then use clean compressed air to blow up. After the replacement of the fine filter with clean oil soaked up, and to join the new oil filter, packed fine filter cover. Use a wash oil cotton wipe oil sump lumen, shave their external oil, and then use wash oil clean the oil sump from inner to outer, and makes it dry, or dry. （ Source: China agricultural mechanization)
