Is gmt floor spring expensive? What does gmt ground spring mean?

Hello, you asked a professional question, not an answer from this industry. Let's not talk about the problem, that is, I have heard of it, and I may not have heard of it. Here, let me check it for you. Gmt floor spring is one of the brands, and the price will be higher. Let me give you a brief introduction for your reference. There are many brands of floor springs in China market, but when it comes to well-known products, gmt is the brand that consumers trust. Among the latest prices of GMT floor springs, the price quoted by this brand still belongs to middle and high-end products in China floor spring market. So the price also reflects the quality of this product from another aspect, so many products of this brand are used in some large-scale fields, such as hotels, guesthouses and so on. Friends who know something about the floor spring market know that there are actually many kinds of floor springs in this field, and as the most deadly brand in China, there are naturally many kinds of gmt floor springs. According to the latest price of gmt floor spring, we can see that the price difference of different models is still very big, ranging from several hundred yuan to thousands of yuan, so consumers must choose the right products according to their own needs. The floor spring is also a hydraulic door closer, but the device that compresses the spring is a worm gear instead of a rack and pinion. Because the worm wheel can rotate back and forth, the ground spring can be used for two-way doors, while the door closer can only be used for one-way doors. The technical key of the ground spring is the bearing seat at the lower part of the spindle, which determines the bearing grade of the ground spring. Because the floor spring used for two-way door opening bears the weight of the door body, the weight of the door body plays a decisive role in the selection of the floor spring relative to the door closer. In practical application, the weight of the door leaf is generally not too large, so choosing the door width and wind pressure is the first choice for the type of ground spring. In addition, pay attention to the aspect ratio, that is, the aspect ratio. If it is out of proportion, the door leaf will not be used normally. From the manufacturing point of view, the worm structure of the ground spring makes the compression degree of the spring less than that of the door closer driven by the rack and pinion, and the force arm of the ground spring to close the door is shorter, so the quality of the ground spring depends more on the structural design and machining accuracy. In addition, the service life of the low-grade floor spring will be very different from that of the high-grade floor spring because the door leaf with two-way door opening exerts great force on the floor spring along the plane of the door leaf. The structure of grounding spring constitutes the basic configuration of grounding spring. The basic configuration of the ground spring is the celestial axis and the ground axis (or foundation). The ceiling shaft is an accessory connecting the door frame and the upper part of the door leaf. It consists of a pin shaft fixed on the door leaf and a shaft sleeve fixed on the door leaf. The sky axis and the earth axis can be applied to almost all wooden, steel and aluminum alloy doors and frameless glass doors using glass door clips. Installation steps and precautions of floor spring: legend of floor spring installation A. Draw a line to make the center of floor spring shaft coincide with the door clamp shaft. B. Make a hole in the ground according to the instruction and the physical object. The size of the hole should be closely matched with the shell of the ground spring and cannot be loosened. C put the floor spring into the open hole and straighten it. D. Lift the door leaf with the door clip installed. Insert the rotating shaft of the floor spring into the rotating shaft hole of the door leaf. E. adjust the screws of the floor spring in three directions. Keep the door leaf vertical and the upper and lower rotating shafts coincide. F. adjust the closing speed. G. cover the floor spring with a decorative cover. The installation accuracy of floor spring has a great influence on its service life. The quality defects of the ground spring mainly include: oil leakage from the body and eccentricity of the ground axis. The oil leakage of car body is caused by the casting process of grounding spring. In the casting process, if the hydraulic pressure in the body increases after sand holes are installed, oil leakage will occur. Eccentricity of the ground axis will cause the door body to deviate from the center line of the door leaf after installation. Although some quality defects can be made up by adjusting the position of the door body, it is best to contact the manufacturer for replacement. The end of the service life of the floor spring is the oil leakage of the shaft, and the elasticity is weakened. If the axis connecting line between the celestial shaft and the main shaft of the ground spring is not strictly perpendicular to the ground, the movement of the door leaf will bring great torsion to the ground spring, increase the wear between the main shaft and the bearing, and eventually lead to oil leakage of the shaft. After a long stretch in spring, it will inevitably weaken its elasticity. Gmt ground spring ends here. I believe you should know something about it. The prices here are for reference only. Subject to the price of the local physical store. Interested friends can choose their own products according to their own needs, hoping to help you.
