Shocking! Substandard oil hose can reduce excavator life by 50%
In the construction industry, excavators are undoubtedly one of the most critical pieces of machinery. Their powerful power and efficient operation allow them to play a leading role in a variety of complex construction environments. However, many people may overlook a seemingly insignificant but crucial component: the oil hose.
As an integral part of the excavator's hydraulic system, the oil hose carries the crucial task of transporting gear oil. Gear oil flows through the oil hose, boosting the power of the excavator's various working devices and ensuring smooth adjustment and rotation of the bucket and boom. It can be said that the oil hose is the "blood vessels" of the excavator, and the gear oil is its "blood."
Unfortunately, there are many substandard oil hoses on the market. These substandard oil hoses exhibit serious defects in materials and manufacturing processes. First, the materials used in counterfeit oil hoses cannot withstand the high pressures generated by the excavator's hydraulic system. During normal operation, hydraulic system pressure fluctuates frequently. Qualified oil hoses, due to their high-quality material properties, can successfully transport gear oil. However, under high pressure, the oil hoses are prone to problems such as loosening and cracking.

Flaws in manufacturing processes are also not to be ignored. Some small workshops fail to strictly adhere to standard operating procedures during the production of oil hoses. For example, the joints of the oil hoses are not welded securely. Under long-term vibration and pressure, the sockets can easily loosen and leak oil. This not only leads to unstable hydraulic system pressure, compromising the excavator's operating efficiency, but also causes significant gear oil leakage, polluting the environment and increasing maintenance costs.
How much damage do oil hoses do to the life of an excavator? Studies have shown that long-term use of oil hoses can reduce the life of an excavator by 50%. This is by no means alarming. When oil hose problems occur, the performance of the hydraulic system is reduced. Gear oil cannot be properly distributed to all working components, causing wear between components.
Take the excavator cylinder as an example. Normally, the cylinder is able to expand steadily, driven by gear oil. If the oil hose is clogged or leaking, the cylinder movement will be blocked, and friction between the piston and the cylinder wall will increase. Over time, the cylinder cavity will become scratched and damaged, and the piston's sealing function will be reduced. This not only affects the normal operation of the cylinder but can also cause failure of the entire hydraulic system.
Furthermore, oil hoses can also affect the excavator's engine. To address the power shortage caused by hydraulic system oil hose problems, the engine must output more power. This puts the engine under prolonged high load, accelerating wear on internal components and reducing its service life.
To ensure the proper service life of the excavator, construction companies and operators must pay close attention to the quality of the oil hoses. When purchasing oil hoses, choose products from reputable manufacturers and review product quality certifications and relevant test reports. Furthermore, regularly inspect and maintain the excavator's oil hoses to promptly identify and replace any problems.
In short, don't underestimate the small components of the oil hoses; they play a crucial role in the life of the excavator. Only by ensuring the use of qualified oil hoses can the excavator perform at its best during construction and provide reliable support for project construction.
