Dirt can cause wear and corrosion of parts, especially for precision machined parts, which can scratch the inner wall of the rubber tube, oil seal ring, and packing. After these things are damaged, more dirt can enter the system, forming a vicious cycle of damage. Overheating will cause rapid oxidation of the oil, which will release insoluble resins, sludge, acids, etc. These substances accumulate in the oil, causing accelerated wear and corrosion of the parts, and they will adhere to the surface of the precision machined parts, causing them to lose their original function. The thinning of oil due to overheating can also slow down the transmission operation.In working oil containing air, there will be sudden jumps and spasms when transmitting power, resulting in uneven power transmission. The resulting pressure fluctuations and stresses will cause damage to components, and in severe cases, the entire system may be damaged. Working oil containing air can also pose a risk of cavitation in hydraulic pumps, resulting in greater suction and drawing more air and other impurities into the system. Overheating occurs due to the entry of air into the oil, which also brings in dust, causing the oil to quickly deteriorate.Air entering the oil not only causes overheating, but also a considerable amount of air is dissolved in the oil under pressure. If about 10% of the compressed volume is dissolved air, foam will be formed when the pressure drops. When the working hydraulic cylinder depressurizes and returns oil, the oil with foam will form“ Sponge” The nature of. In addition, the oil containing many foam will increase the total volume, which will cause oil spill in the oil tank or oil reservoir.If the manufacturing quality of the hydraulic system is not a problem, the cause of the malfunction is mostly due to improper preventive maintenance, and there are generally fewer factors of improper operation. The main reason for this is due to insufficient understanding of its working conditions. If you understand some basic principles and comprehend the three harmful factors that cause faults, you can ensure that the system is in good working condition for a long time.Repair various construction machinery, providing repair services for thousands of excavators over the years, as well as engine repair, hydraulic pump repair, hydraulic system and multi way valve repair, rotary drilling rig repair, paver repair, etc. All the accessories provided are genuine factory parts.
