4、ct the lubrication of diesel lubricantsDiesel engine used in the lubricant oil and butter, most of the moving parts is the use of oil to lubricate, only to lubricate the shaft and the bearing of the pump, start the engine, generator and other components using butter. First, oil the selection ofA Cum

5、mins engine of the world's only elected oil "Extreme Blue" Premium Biue oil, the oil's performance level for the CH - 4/SJ viscosity grade 15W - 40 for Cummins series engine.Domestic diesel engine the group is generally the Great Wall brand oil.Two, how to use some simple method of

6、 testing oil quality is the status1 Appearance: The oil is milky white or mist, that the oil into the water; oil grayed out, may be contaminated by the fuel; oil change black, is caused by a product of incomplete fuel combustion.2 Odor: pungent odor, indicating that the oil temperature oxidation; ha

7、s a very strong smell of fuel, indicating that severe fuel dilution (with a small amount of fuel smell is normal).3 droplets spot test: Remove a drop of oil drops on filter paper, observe the change of its spots. The oil quickly spread, with no sediment, indicating that the oil is normal; the middle

8、 of the sediments, showed that the oil is dirty and should be replaced immediately.Third, the replacement of diesel oilStart the engine idle for 2-3 minutes so that the engine temperature rose to normal operating temperature, turn off the diesel engine. Hot to waste lubricating oil to a net release

9、(including crude oil filter and radiator). Waste oil into waste oil container recycling to the reduce pollution.Oil and diesel, the ratio of 1:1 to the preparation of cleaning the oil, cleaning oil to require the oil level, start the engine, medium-speed (rated speed at 750-1000 rpm / min) run for 1

10、0 minutes, while it is hot clean oil put the net when necessary, cleaning twice.Cleaning and replacement of oil the filter, disposable filter must be replaced.4 Install the new by-pass filter to the filter to inject as much as oil.5 in accordance with the provisions of the user manual, select the ap

11、propriate viscosity and quality level of the lubricating oil poured into the injection port. View the oil gauge, to determine the full scale in the static position, start the engine-load operation for 2-3 minutes, check for oil leakage from the oil pan or oil filter, if everything is normal, replace

12、 the end of the oil program.The four basic functions of the four diesel engine. Lubricating oilThe diesel engine lubricating oil of the four basic functions: to reduce friction, cooling, sealing, cleaning.1 to reduce the friction is the essential function of the diesel engine lubrication system and

13、diesel engine lubricating oil supply to the moving parts, friction will cause rapid wear of the diesel engine life will become very short, and can even say you can not run.2 cooling is another important feature of the diesel engine lubrication system, oil must absorb the friction of the moving parts

14、 and combustion heat generated. Combustion chamber temperature is often as high as 2,200 ° C, and passed to the heat of diesel engine parts must be taken away. The cooling function is done through the lubricating oil. The oil absorbed the heat of the diesel engine, the heat transfer to the engi

15、ne water jacket, to bring it to the sump. Where the heat into the atmosphere, or to bring it to the oil cooler, oil cooler heat transferred to the diesel engine cooler.3 lubrication system also performs a sealing function, or plug the effective implementation of its main function, and lubricants to

16、form a film between the piston and cylinder walls, to ensure full sealing. Film, the expansion of the energy of the gas would be a waste.4 cleaning function is also a major function of the lubrication system, oil must be able to effectively take away or remove many different types of impurities. Fue

17、l combustion generated oxides, water vapor, incomplete combustion of carbon deposition, metal particles, such as impact from the metal surface, these wastes remain in the bearing surface on the diesel engine is harmful. Efficient oil containing additives necessary to remove these byproducts, diesel

18、collar kept clean and effective work.Fifth, the role of oilA lubricating effect: moving parts at high temperatures, high speed and under high pressure operation, dry grinding to produce a lot of heat to the metal wear, melting, and even sintered intermetallic. Engine oil to the crankshaft, connectin

19、g rod, piston, cylinder walls, camshaft, valve and other parts in the formation of a layer of oil film between the friction, prevent metal damage.Cooling: the heat generated from fuel combustion only 30% - 40% converted to mechanical energy, and the rest consumed in the friction outside, but also th

20、e engine heat. A lot of engine oil flow from the friction surface can take the heat will not protect the engine. temperature is too high and burned.The sealing effect: the piston of the engine cylinder, piston rings have a certain clearance between the piston groove, to ensure the freedom movement o

21、f the piston. Engine oil filling during which the formation of oil seals, so that does not leak, keep the cylinder pressure, thus ensuring the engine power play. Oil seals play at the same time prevent the exhaust fleeing into the role of the crankcase contamination and dilution of lubricating oil.4

22、 cleaning effect: formation of coke fuel combustion, lubricant oxidation of colloidal material, the moving parts of friction of metal shavings and dust into the air, the engine parts formed on the surface sediments and varnish. Engine oil through the cycle, its unique active ingredient in a timely m

23、anner to the sludge and impurities away, a coarse and fine filters to remove harmful substances, to ensure the normal operation of the engine.5 anti-rust and anti-corrosive effect: corrosion from water, acid, air and lubricant oxidation products. Engine oil by adding anti-rust and anti-corrosion add

24、itives and has a good anti-corrosive effect.6 buffer dispersed impact: film fluid cushion can be decentralized to ease the impact, to absorb vibration. 6, oil oxidation harmAn oxidation of the acidic material may corrode metal parts, and will intensify in the water. And produce organic acids, iron s

25、alts, copper salts, lead salts and other dissolved substances.Produce various oil-soluble and easy to plug the oil and filter sediment, in the lubrication system, disruption of normal lubrication and impact of the thermal conductivity, and serious damage to parts such as bush.3 oxide deposited on th

26、e valve on the piston ring slot, it will burn out the valve, bonded piston ring.Formed by oxidation of 4 oil varnish adheres to the piston ring, piston ring loses its elasticity, increase friction, reduce engine power output. Will result in the bad cylinder and piston closed, resulting in the phenom

27、enon of channeling gas and oil burning.Seven, the oil in use why bubbleThe foam is a diesel engine operation, oil is subject to intense agitation, air agitation into the oil formation. A lot of foam on the normal work of the diesel engine have an adverse effect, it reduces the sealing effect, so tha

28、t the cooling effect is reduced. Moving parts can not get enough lubrication. Therefore, anti-foam performance diesel engine oil is very important.A, bubble generated the following factors1) the influence of viscosity and temperature. Viscosity to teach large, foaming tendency of stability, the temp

29、erature increases the viscosity decreased.2) long-term use after the oil oxidative deterioration and decomposition of the resin and asphaltene and sludge will contribute to blistering.3) the amount of oil is too much or too little. Too much oil stir radical exacerbated foaming tendency, too little f

30、uel, the pump is easily pumped into the air bubble.4) oil by water on the C. A pollution prone to bubbles.Eight diesel why replacement of oilThe diesel engine lubricating oil additives in their work continue to be consumed, so that the lubricant performance declining, dust, sludge and diesel engine

31、operation, the iron filings, water, acid, soot and carbon deposits will accumulate in the diesel internal. Lubricating oil additives account for 15 - 30% of the lubricating oil, only to work in a certain period of time to fully protect the diesel engine. Time is too long, additives consumption growing to
