Recently, many owners of cleaning vehicles are asking why the exhaust pipe of my car is always dripping. At each stop, there is a pool of water on the ground. Is the engine problem? Or the generator of the exhaust pipe has a problem? The following small series to answer everyone.

In fact, it is normal for the automobile exhaust pipe to be dripping, which means that the engine is in good condition. Water is the fogging effect produced by the combustion of the engine. In winter, we can see that the exhaust gas from the exhaust pipe of the car is fogged. This shows that the sweeper engine works well.

The reason for dripping water in the exhaust pipe of a car is to generate water and carbon dioxide after the gasoline is completely burned. The water produces steam at high temperatures, and the water vapor is colorless and transparent at high temperatures. We cannot see it, but when the temperature is lower than 100 degrees. Afterwards, water vapor condenses into water. If the condensed water droplets are small and suspended in the air, the water vapor is a white gas. When the ambient temperature decreases, the white smoke emitted by the exhaust pipe is water vapor; after the water droplets have accumulated, the water becomes water. If there is a large amount of water vapor and white smoke in the exhaust pipe when the engine is running, check the tank for stagnant water at this time, check whether the cylinder is damaged, whether there is a crack in the cylinder, and whether the seal of the cylinder liner is good.

Sometimes the exhaust pipe will be black, even black water. The reason why the phenomenon of black water drop occurs is that the engine eats oil. Before the road, pay attention to the oil stock of the sweeper . If the engine runs for a period of time, the temperature rises and the exhaust pipe emits black smoke. This indicates that the cylinder pressure is too low or the individual cylinders have already gone on strike. At this time, they must go to the maintenance factory for inspection and maintenance.

To sum up, we can know: if the exhaust pipe shows that the engine works well, the exhaust gas is misty to indicate that the engine is in good working condition. However, if a large amount of water accumulates in the exhaust pipe, it will lead to corrosion of the exhaust pipe. At this time, it is necessary to clean the water and find a ramp and a few throttles. If you have been drip, you can go to the car manufacturer to repair it.

Daily maintenance of excavator hydraulic cylinders
The hydraulic cylinder of an excavator is one of the important hydraulic components responsible for driving and controlling mechanical movements. In order to ensure the normal use of hydraulic cylinders and extend their service life, daily maintenance is necessary.
1. Regularly clean the hydraulic cylinder: During use, the hydraulic cylinder will be attacked by various pollutants, such as dust, sediment, oil stains, etc. These pollutants can affect the working efficiency and lifespan of the hydraulic cylinder. Therefore, it is necessary to regularly clean the hydraulic cylinder.
2. Regular inspection of seals: The seals of hydraulic cylinders are key components to ensure their normal operation. If the seals are damaged or worn, it can lead to oil leakage or unstable operation of the hydraulic cylinder. Therefore, it is necessary to regularly inspect the sealing components of the hydraulic cylinder and replace them in a timely manner if there is any damage or wear.
3. Regular inspection of hydraulic oil: The operation of hydraulic cylinders requires the support of hydraulic oil, so the quality of hydraulic oil has an important impact on the working effect of hydraulic cylinders. Regularly check the quality of hydraulic oil, and replace it promptly if there is contamination or deterioration.
4. Regularly check the hydraulic pipeline: The hydraulic pipeline is the blood vessel of the hydraulic cylinder. If there is oil leakage or damage to the pipeline, it can cause the hydraulic cylinder to not work properly. Therefore, it is necessary to regularly inspect the hydraulic pipelines and promptly repair or replace them if there is any oil leakage or damage.
5. Regularly lubricate the hydraulic cylinder: The piston rod and piston ring of the hydraulic cylinder need to be lubricated to reduce wear and friction. Therefore, it is necessary to regularly apply lubricating oil to ensure the normal operation of the hydraulic cylinder.
In short, the daily maintenance of excavator hydraulic cylinders is very important, which can extend their service life and improve work efficiency. Regular cleaning of hydraulic cylinders, inspection of seals, hydraulic oil, hydraulic pipelines, and lubrication of hydraulic cylinders are required.
