The Difference Between Floor Springs And Door Closers
Door closers and floor springs are more likely to be encountered in everyday life as door control products than automatic door control products (automatic door machines). Floor springs and closers are commonly used on doors in shopping centers, office buildings, residential areas, hotels and other public places. The main function is to ensure that the door can be opened properly or that it can be closed to its initial position in an accurate and timely manner. What is the difference between the two, which are also door control products and have such similar performance? When you need to buy a door closing products and how to choose what you need? Let's explore it together!
The core of the door closer design thinking is to achieve control of the closing process, so that you can adjust the closing process according to human needs of various functional indicators. For example, closing speed, locking speed, etc. The significance of the door closer is not only to automatically close the door, but also to protect the door frame and door body. Door closers are mainly used in commercial and public buildings, but they are also used in homes. They have many uses, the most important of which is to make the door close by itself to limit the spread of fire and ventilation in the building.
Although ground springs are considered hydraulic door closers, the mechanism used to compress the spring is a turbine rather than a rack and pinion. The basic configuration of a floor spring is a sky shaft and a floor shaft. The overhead shaft is the fitting that connects the door frame to the door sash at the top. It consists of a bolt-type shaft fixed to the door sash and a sleeve fixed to the door sash.
Installation Position Is Different
A major difference between door closers and floor springs is that the installation position is different. Door closers are often installed above the door, while floor springs are installed below the door's door shaft. Seen the store glass doors are clear, the basic is always closed glass doors, push up the effort, and the ground is installed under the ground spring.
Different Functions
Another major difference between door closers and floor springs is that door closers have the function of automatically closing the door. But the door closer can only open the door in one direction, while the door controlled by the floor spring can open the door in two directions. The reason for this is that the spring-compressing device of the floor spring is a worm gear instead of a gear or rack. Because the worm wheel can rotate in both directions, the floor spring can be used for doors that open in both directions.
Different Load-Bearing
Another big difference between door closers and floor springs is in the selection of products, because the floor springs for bi-directional doors have to carry the weight of the door body, compared to door closers, the weight of the door body plays a decisive role in the selection of floor springs. In practice, the weight of the door is usually not too much, so the door width and wind pressure are the preferred factors for the selection of the floor spring model. Also pay attention to the aspect ratio, i.e. the ratio of height and width, if it is too disproportionate, the door will not work properly.
Different Composition
Door closers and floor springs in addition to the above differences there is a fundamental difference is the composition of different. The basic components of the door closer are the support guide, transmission gear, reset spring, one-way valve, rack and pinion plunger, throttle core and shell, end caps, seals and connecting rods. The shell and the connecting rod play a role in fixing the door closer and connecting the door fan to the door frame. The basic configuration of the ground spring is the sky shaft and the ground shaft (or the ground foot). The sky shaft is an accessory that connects the door frame and the door fan in the upper part, and consists of a pin-type shaft that can be adjusted with a bolt fixed to the door fan and a sleeve fixed to the door fan. The technical key of the floor spring is the load-bearing seat in the lower part of the spindle, which determines the load-bearing level of the floor spring.
GEKRONE floor spring body is ultra-thin and light, using imported springs, which can run 500,000 times; using low-temperature anti-freeze hydraulic oil, which keeps the door closed smoothly under -40℃, controlling the floor spring load-bearing force through special torque design, reducing the use of opening and closing the door, using high-strength leak-proof structure, preventing damage or oil leakage caused by external strong pressure or strong wind condition, prolonging the service life, adjustable in the cement box Length 5mm, width 5mm can be adjusted longitudinally ± 2 ° when calibrating the zero position, making the product more convenient to install.
GEKRONE door closer with specially designed high precision oil seal to prevent oil leakage from the body, high strength body, is the fundamental guarantee of quality, imported high-quality hydraulic oil, regardless of cold and heat can ensure that open automatically, smooth operation, stable quality, durable. HD8000 also has backcheck and delay action function. Our products have UL fireproof certification and American Standard Class I certification, can be used in the fire door with confidence.
