First of all, hydraulic hoses, as pipeline connections in the hydraulic system, undertake multiple functions such as transmitting hydraulic oil, withstanding pressure, sealing, and protecting. Its excellent pressure resistance and flexibility enable it to withstand the transmission of high-pressure hydraulic oil and adapt to deflection and deformation during mechanical movement. The selection of materials and the application of sealing technology directly affect the reliability and durability of the hydraulic system.

Secondly, hydraulic hoses can effectively transmit mechanical power. In construction machinery, the hydraulic system converts the input mechanical power into hydraulic energy through a hydraulic pump and transmits it to the hydraulic actuator through the hose system to drive various tasks of the machinery. This transmission method is efficient and flexible and can meet the needs of construction machinery under different working conditions, such as lifting, movement, steering, etc.

In addition, hydraulic hoses can also withstand impact, vibration and large-scale movements during mechanical work, and have good wear resistance, aging resistance and high temperature resistance. In harsh environments such as construction sites, the excellent characteristics of hydraulic hoses can ensure the normal operation of the hydraulic system and improve the stability and reliability of construction machinery.

However, due to the complex and changeable working environment of construction machinery, the service life of hydraulic hoses will be affected to a certain extent. Therefore, regular inspection and maintenance are particularly important. For hydraulic hoses that are aging, severely worn or leaking, timely replacement is a key measure to ensure the safe operation of the hydraulic system.

To sum up, hydraulic hoses, as a key component of the hydraulic system in construction machinery, inject powerful power into the machinery and have multiple functions such as bearing pressure, transmitting power, and sealing protection. Its excellent performance can effectively support the working needs of engineering machinery under various working conditions and improve work efficiency and mechanical stability. Therefore, in the design, production and maintenance process of construction machinery, the role of hydraulic hoses is irreplaceable, and its quality is directly related to the reliability and safety of the hydraulic system.  

In future development, the hydraulic hose industry will continue to innovate and improve to adapt to the continuous development of construction machinery and the increasing demand. At the same time, users should also pay more attention to hydraulic hoses and establish a sound maintenance and replacement system to ensure the normal operation of the hydraulic system and provide reliable guarantee for the efficient and safe operation of construction machinery.
