Water inflow of engine oil in water well drilling rig can be said to be a common fault problem. A master with sufficient experience can directly judge the quality of engine oil used in the machine from the color, smell and viscosity of the oil. Today, we will talk about how to judge the oil inflow of the drilling rig engine, the main causes of the inflow and the treatment measures.
First, how to judge the oil water
1. Observe the oil dipstick
If the amount of water contained in the engine oil is relatively large, the oil level of the oil will rise. At this point, we can judge by dipstick. Once the water content in the oil is too high, the level of the lubricating oil will exceed the range marked on the dipstick.
2. Check the engine coolant
Check engine coolant for oil. If some parts of the engine are damaged, the engine coolant will enter the lubrication system, and oil is often found in the coolant.
3. Observe the color appearance of the oil
Careful observation of the appearance of the oil can also easily determine whether the oil contains water. Oil that does not contain water is translucent and bright, while oil that contains water is opaque brown or yellow. If the engine oil contains moisture, the engine oil will show Milky White and foam after the engine has been running for a period of time. This is because under the action of the high temperature inside the engine, the oil and the coolant chemically react, and the oil will be emulsified into an emulsion.
Second, the main reason for the oil water
1. Damage to the oil radiator causes the oil to enter the water. The oil radiator is damaged, the radiator pipeline is broken, and the water outside the radiator will penetrate into the oil radiator, causing the oil to enter the water.
2. The damage to the sealing ring of the cylinder liner causes the oil to enter the water. The wet cylinder liner directly contacts the cooling water. The sealing ring at the lower part of the cylinder liner can effectively prevent the leakage of oil and cooling water. In use, the sealing ring bears a certain pressure, and sometimes the poor water quality of the cooling water will cause corrosion. After the engine runs for a long time, the sealing ring is easy to fail. Cylinder liner sealing ring damage is a major cause of oil water, so, when checking the cause of oil water, be sure to remember to check whether the cylinder liner sealing ring is intact.
3. Cylinder liner cracks easily lead to oil water? When the heating cylinder liner directly contacts the cooling water, it is easy to produce cracks. Once cracks occur, the cooling water will directly enter the cylinder and enter the oil pan through the cylinder wall. This will make the oil white, and the oil white will lead to poor engine combustion, white smoke and other problems.
4. Damaged cylinder head gasket leads to oil water ingress? Engine cylinder head gasket is used to seal each cylinder and the corresponding water channel and oil channel of each cylinder, so as to avoid oil ingress. If the cylinder head gasket is damaged and the water circulation speed is fast, the water in the water channel will flow into the oil passage, causing the oil to enter the water. Tip: Cylinder head gasket damage is one of the important reasons for oil water ingress. After each disassembly of the machine, try to use a new cylinder head gasket to avoid oil water ingress caused by cylinder head gasket leakage, which may cause engine damage.
Three, how to deal with oil water
If the oil enters the water lightly, it will cause the engine temperature to be too high, if it is serious, it will cause failures such as cylinder pulling and tile holding, and if it is more serious, it will cause the engine to be scrapped. In general, the water content in the oil is below 0.03 percent, and if the water content exceeds 0.1 percent, the additives in the oil (e. g., antioxidants, detergents, dispersants, etc.) will react with water and fail, and the performance of the oil will decline.? Under the action of the high temperature inside the engine, the oil will chemically react with the coolant, the oil will be emulsified, and the lubrication effect of the oil will be greatly reduced. After the oxidation resistance of the engine oil decreases, the organic acid produced by the oxidation of the engine oil will react with water to form inorganic acid, and these acidic substances will cause corrosion to the engine parts, causing the parts to rust or damage.
1. Water ingress of engine oil can be said to be a common fault, and we can judge whether the oil has entered water by observing the appearance color of the oil, the oil level of the oil, and the observation of the oil coolant.
2. If water ingress is found in the oil, we can also check the oil radiator, water plug, cylinder liner sealing ring, cylinder liner, cylinder head gasket, etc. to determine the cause of the oil ingress.? After the engine oil of the water well drilling rig enters the water, if it is not handled in time, it will cause more serious consequences, such as faults such as cylinder drawing and drawing. The more serious ones will cause the engine to be scrapped. Therefore, always pay attention to keeping the water away from the engine oil.
