You think it is a cost saving, but in fact it is spending money!
On weekdays, many excavators will add oil into the diesel engine, and when asked why, they all agree that the oil is much cheaper than diesel oil, which can save a lot of cost. However, it is not known that this method will seriously cause the increase of the temperature of the excavator, the more serious operation is slow, when the oil mixed with diesel oil will aggravate the oil fluid in the tank, which causes the failure of the mechanical parts lubrication to aggravate the degree of wear. Therefore, it is very undesirable to use oil in diesel engines.
Next, Xiaobian will explain to you why the oil of excavator can not be mixed.
Reducing oil performance
The biggest difference between the new oil and the old oil is that there is a lot of oxygen in the old oil, which makes the oil produce a lot of oxide. When the new oil is mixed with these oxygen - containing old oil, the oxidation speed of the new oil will be greatly accelerated, thus causing the oil to deteriorate so that the normal service life of the oil can not be reached.
A data experiment has shown that the oil in a excavator tank is all used and then a new oil is added once, and the other half of the new oil is added when the engine is used in half of the tank. The synchronous operation of the excavator under the condition of two clocks is used. By contrast, it is found that the use of all the new oil excavators can be up to 1500 hours for a long time, while the use time of the excavator with new and old semi oil is only 200 hours, and the comparison of the use life of the excavators shows that the use life of the two is far away.
Therefore, experiments show that the use of old and new half will seriously affect the service life of oil.
Oil metamorphism
Because of the chemical difference in different brands and types of oil, special attention should be paid in the process of use. If the mixed use of different brands and types of oil will cause adverse chemical reactions, the acid and alkali compounds produced by them will aggravate the corrosion of parts and components, and then affect the lubrication effect of mechanical parts.
5 major hazards after the mixing of the oil in the excavator:
1. The discoloration of the piston rod or piston ring
2. Fracture of piston ring
3. The abnormal smoke of exhaust pipe
4, speed up the formation of oil sludge
5, the wear and tear of piston and cylinder are serious
The influence of the machine oil on the excavator:
1, if the oil of the excavator is too small, it will easily cause the cylinder to be pulled out.
2, too much engine oil will have an impact on the power of the excavator. Assuming that you do the move on the ground is absolutely not hard, if you do it in the water, it will be much harder than on the ground.
3, too much oil can also easily cause the phenomenon of oil and oil, so the oil should be added according to the standard, a certain type of oil that conforms to the driving environment, must not be mistaken, so that you will reduce the unnecessary loss.
4. The oil of the excavator is increased, and the phenomenon of oil consumption of excavators may also occur.
5, the engine oil is more damage to the engine, the pressure increases, the crankshaft oil seal, causing oil leakage, smoke, high temperature, and oil into the cylinder burning black gum, damaging the cylinder.
The excavator is a high precision instrument for the integration of mechanical and electrical fluid, so no matter how much oil or too little oil is added, it will affect the excavator. Therefore, when the excavator is refueling daily, it should be strictly in accordance with the standard standard, and then the failure of the excavator will be reduced.
