Do you know the risk situation caused by the mixing of water in the hydraulic system of the excavator? Today, I will take everyone to take a look at the adverse effects of water intrusion in the hydraulic system.
1. When the oil is mixed with water, the hydraulic oil will have an emulsification reaction. Once the hydraulic oil has poor anti-emulsification ability, it will cause the hydraulic oil to separate from the oil in a short period of time. If things go on like this, the emulsified oil accumulates into the hydraulic system, causing its internal components to corrode and rust, reducing its wetting level, and ultimately endangering all the normal operation of the hydraulic system.
2. Deterministic preservatives in water and oil cause chemical changes to produce precipitation and collagen fibrosis, leading to increasingly serious malignant changes in oil.
3. Sulfur and chlorine substances in water and oil cause chemical changes to produce hydrochloric acid and sulfuric acid substances. The cause of this substance will immediately cause the corrosion damage of the components in the system to increase, and accelerate the oil and air oxidation.
4. After the metal material in the hydraulic system is rusted, the rust residues that fall will follow the fluidity of the hydraulic system pipeline, and then gradually diffuse into the entire hydraulic system, causing more serious air oxidation and residues. accumulation.
Fifth, in the ultra-low temperature natural environment, the water solidifies into ice crystals, which is one of the key reasons that cause the gap between components to be blocked.
These five points are summarized in the summary about the damage caused by the water mixed in the hydraulic system. In the future maintenance, everyone should be vigilant and resolute to put an end to this seemingly insignificant small key point. Ignoring the key point usually leads to great Disaster.
