The floor spring is a hydraulic door closer, but the device that compresses the spring is a worm gear instead of a rack and pinion.
Because the floor spring used for two-way opening must bear the weight of the door body, the weight of the door body plays a decisive role in selecting the floor spring compared with closing the door.
In practical applications, the weight of the door leaf is usually not exceeded, so choosing the width and wind pressure of the door on the hydraulic spring model is the first choice. Also pay attention to the aspect ratio, that is, the aspect ratio. If the ratio is too large, the door leaf will not work properly. Moreover, the weight of the door exceeds the weight of the original hydraulic spring, so the door leaf is prone to accidents.
The basic configuration of the floor spring is the sky axis and the earth axis (or feet). The sky shaft is an accessory used to connect the door frame and the upper door leaf. It is composed of a bolt-shaped shaft fixed on the door leaf and adjustable by bolts and a shaft sleeve fixed on the door leaf. It is suitable for almost all wood, steel, aluminum alloy doors and frameless glass doors. The installation accuracy of the floor spring has a great influence on its service life. Because the end of the service life of the floor spring is oil leakage
From the perspective of installation, the service life of the floor spring is also an issue that needs to be considered. If you choose a manufacturer that is cheap and cannot guarantee quality, the service life of the floor spring may be greatly shortened, and the shortened service life of the floor spring may cause oil leakage and prevent the door leaf from working properly. Therefore, choosing a qualified and reliable manufacturer is more important than anything else!
