Why do hydraulic hoses need to be replaced regularly?

A hydraulic hose is an indispensable component of the hydraulic system. It undertakes the important task of transmitting hydraulic capacity and protecting the hydraulic system. However, due to long-term use and environmental factors, hydraulic hoses will have problems such as aging, wear, and damage, so they need to be replaced regularly. This article will discuss the working principle of hydraulic hose, the cause of aging, and the necessity of regular replacement.

First, let's understand the working principle of hydraulic hose. A hydraulic hose realizes mechanical movement by transmitting liquid pressure to various components of the hydraulic system. It consists of an inner rubber layer, a reinforcement layer, and an outer rubber layer. The inner rubber layer plays the role of sealing and transmitting hydraulic capacity, the reinforcement layer increases the strength and pressure resistance of the hose, and the outer rubber layer plays the role of protecting the hose. When the hydraulic system is working, the hydraulic oil flows through the hose and generates pressure, thereby driving the hydraulic cylinder, hydraulic motor, and other actuators to complete the work.

However, due to long-term use and environmental factors, hydraulic hoses will have problems such as aging, wear, and damage. First of all, the inner rubber layer of the hydraulic hose will gradually age due to the erosion and friction of the hydraulic oil, resulting in a decrease in the sealing performance of the hose, which will cause leakage problems in the hydraulic system. Secondly, during the working process, the hydraulic hose will be impacted by the friction of high-pressure liquid, causing the hose surface to wear and rupture, which will cause pressure loss and leakage in the hydraulic system. In addition, the hydraulic hose will also be affected by factors such as temperature changes, chemical erosion, and mechanical vibration, which will gradually reduce the performance of the hose.

In view of the aging and damage of the hydraulic hose, it is very necessary to replace the hydraulic hose regularly. First of all, regular replacement of hydraulic hoses can ensure the normal operation of the hydraulic system. Leakage problems in the hydraulic system will lead to loss of hydraulic capacity, thereby affecting the working efficiency and performance of mechanical equipment. Regular replacement of hoses can promptly repair leakage problems and ensure the normal operation of the hydraulic system. Secondly, regular replacement of hydraulic hoses can improve the safety of the system. Leakage problems in the hydraulic system will not only lead to energy waste but also may cause safety accidents such as fire and explosion. Regular replacement of hoses can avoid the occurrence of these safety hazards. In addition, regular replacement of hydraulic hoses can also extend the service life of the hydraulic system. Aging and damage of the hose will lead to pressure loss and leakage in the hydraulic system, which will increase the load of actuators such as hydraulic pumps and hydraulic motors and shorten their service life. Regular replacement of hoses can reduce these loads and extend the service life of the hydraulic system.

So, how to regularly replace hydraulic hoses? First of all, it is necessary to regularly check the appearance and connection parts of the hydraulic hose. If the hose surface is found to have problems such as wear, cracks, or deformation, or the connection parts are loose or leaking, it is necessary to replace the hose or repair the connection parts in time. Secondly, it is necessary to regularly check the pressure and temperature of the hydraulic system. If the pressure and temperature are found to be abnormal, it may be caused by aging or damage to the hose, and the hose needs to be replaced in time. In addition, it is necessary to regularly replace the hydraulic oil and filter element to keep the hydraulic system clean and working properly.

In summary, hydraulic hoses, as important transmission and protection devices in hydraulic systems, need to be replaced regularly. Regular replacement of hydraulic hoses can ensure the normal operation of the hydraulic system, improve the safety of the system, and extend the service life of the system. Therefore, we should attach importance to the regular inspection and replacement of hydraulic hoses to ensure the stable operation and safe use of the hydraulic system.
