General Service Life for Floor Spring

There is a wide variation in the quality of floor springs themselves. High - quality brand - name floor springs usually use better materials, such as high - strength spring steel, wear - resistant sealing materials, and high - quality hydraulic oil (for hydraulic floor springs). Their internal mechanical structure design is also more reasonable, and the manufacturing process is more precise. These factors enable them to have a relatively long service life.

Harsh environmental conditions can have an adverse impact on the floor spring. For example, in a humid environment, the metal components of the floor spring are prone to rust, especially products that have not been well - protected against rust. In an environment with a large amount of dust and sand, these impurities may enter the interior of the floor spring, increasing the friction between the components and even clogging the hydraulic system (for hydraulic floor springs), affecting their normal operation and thus reducing the service life.

Correct installation is a prerequisite for the normal use of the floor spring. If the floor spring is not installed horizontally during installation, or the connection with the door body is not firm or accurate, additional friction and stress will be generated between the components during the opening and closing of the door. This will not only lead to problems such as abnormal noise and jamming but also accelerate component wear and shorten the service life.

Heavier and larger doors exert more pressure on the floor spring. For example, heavy solid - wood doors or large - scale glass revolving doors require the floor spring to have a higher load - bearing capacity. If the load - bearing specification of the floor spring does not match the door and it bears an excessive load for a long time, the internal components such as the spring, the rotating shaft, and the hydraulic system (if it is a hydraulic floor spring) will be damaged more quickly, thus reducing the service life.

This is a crucial factor. In high - traffic commercial areas such as shopping centers, supermarkets, and hotel lobbies, the door may be opened and closed hundreds of times a day or even more. Such frequent use will accelerate the wear of the internal components of the floor spring and lead to a shortened service life. In contrast, in a domestic environment or an office with a low frequency of use, the door is opened and closed less frequently, and the floor spring may last longer.

Under normal operating conditions, that is, with correct installation, the door's weight and size being suitable, a favorable operating environment, and qualified product quality, the service life of an ordinary floor spring is approximately 3 - 5 years. However, if it is a high - quality floor spring used in a high - traffic commercial area, its service life may be around 2 - 3 years; while in a low - traffic domestic environment, the service life may be extended to 5 - 8 years or even longer. For high - end, heavy - duty floor springs used for the doors of large - scale commercial buildings or industrial sites, their designed service life may reach 10 years, but this also needs to be judged in combination with the actual usage situation.
