What are the types of floor spring?
How to choose floor spring?
The basic components of hydraulic door closer include supporting guide, transmission gear, return spring, one-way valve, rack plunger, throttle valve core and shell, end cap, sealing ring and connecting rod. The basic configuration of floor spring is the ceiling shaft and anchor.
Door closer can only be used for one-way open doors, while the floor spring can be used for two-way opening doors because the worm gear can rotate forward and backward.
The door closer is not only to automatically close the door, but also to protect the door frame and door body to close smoothly. More importantly, door closer has become an executive part of intelligent management of modern buildings. The technical key of the floor spring is the bearing seat at the lower part of the main shaft, which determines the bearing grade. The floor spring is one type of door closers.
There are many sizes of floor springs for glass doors that the appropriate door width 900mm, 1000mm, 1300mm, 1500mm, and 1600mm.
Luxury and economical floor springs have almost the same overall dimensions, the applicable angle of the door leaf, and some characteristics are similar. But the fan weight bearing capacity of the luxury floor spring is larger. The economic floor spring is suitable for one-stage speed adjustment, while the luxury one is suitable for two-stage speed adjustment.
The heavy floor spring is larger than others in appearance that the maximum load-bearing of the door leaf is 230 to 300kg and the applicable angle of the door leaf is 1200mm to 1500mm. The lightweight floor spring has a small shape that the load-bearing capacity of the door leaf is only 90kg and the use angle of door leaf is 800-900mm. However, the characteristics of these two types of floor springs are the same, which are two-way opening type of center arm, 90 ° stop device and two-stage speed adjustment.
The action range of fireproof and moisture-proof floor springs is similar. But the fireproof floor spring is longer than the waterproof floor spring with smaller in width and height. In terms of the load-bearing size of the door leaf, the fireproof floor spring should be higher than the waterproof floor spring and the applicable of the door leaf also be wider.
Choosing floor spring is more over similar to door closer. In addition to weight capacity, other criteria may include door dimensions with door weight and width, closing speed variation, control over the rate of closing, safety, durability, door closer’s performance in fire situation, anti-ligature and aesthetics.
The size of floor spring is selected according to the size and weight of the door. Add the weight of all accessories and the weight of glass to get the weight of the whole door.
It is not that the larger the size of the floor spring, the better it is. If the size of the floor spring is too large, it will be very laborious to open the door. Therefore, it is good to be appropriate to the specification of the door.
The floor spring with insufficient bearing capacity also directly affect the service life.
The floor spring of antifreeze hydraulic oil shall be selected in cold areas. The speed regulating button shall be properly adjusted in winter.
