What are the hazards of abnormal oil to the vane pump?
I believe that friends who know oil should know that normal oil can lubricate and provide power, but due to our living environment and the oil itself, it may cause abnormal changes in the oil. For example, the oil quality deteriorates and pollutants are mixed in. These changes have a serious destructive effect on the vane pump of construction machinery. Today I will tell you about the harm of abnormal oil to the vane pump as follows:
Accelerate the deterioration of oil performance
1.The heat energy of water and air in the oil is the main condition for the oxidation of the oil, and the metal particles in the oil play an important catalytic role in the oxidation of the oil. In addition, the water and suspended air bubbles in the oil significantly reduce the The strength of the oil film between the moving pairs reduces the lubricating performance.
Component blockage and clamping failure
1.Solid particles block the gap and orifice of the hydraulic valve, causing the valve core to be blocked and clamped, affecting the working performance and even causing serious accidents. According to statistics, about 70% of the vane pump failures at home and abroad are caused by pollution.
2.Therefore, the quality of a vane pumpnot only depends on the rationality of the system design and the performance of the system components, but also the pollution protection and treatment of the system. The pollution of the system directly affects the reliability of the vane pump and the reliability of the components. service life.
Contamination and wear of components
1.Various pollutants in the oil cause various forms of wear of the components, and solid particles enter the gap of the moving pair, causing cutting wear or fatigue wear on the surface of the parts.
2.The impact of solid particles in the high-speed liquid flow on the surface of the component causes erosion and wear. The water in the oil and the products of oxidation and deterioration of the oil will corrode the components. Additionally, air in the system's fluids causes cavitation, leading to erosion and destruction of component surfaces.
