INTRODUCTION
Floor Spring is used for glass door, and they can be used together with door clamp. Floor Spring can be opened with double sizes, and on this point, it is different from that of door closer, which can just be opened by one size. The key of technique lies on the loading seat under the main bearing, which decides the level of loading on the floor spring. Usually it can be opened from 300thousand or 1million times

SPECIFICATION
INSTALLATION STEPS
1. Draw lines and make floor spring pivot center and door-nip pivot coincide with each other.
2. Drill holes on the floor according to the instructions. The sizes of the holes must tightly match the floor spring.
3. Place the floor spring into the holes and position it.
4. Raise the door leaf installed with door-nip, and insert the floor spring pivot into the hole of the door leaf.
5. Adjust the screws at three directions. Make them vertical and the upper and lower pivot center coincide with each other.
6. Adjust the speed of door closing.
7. Put the decoration cover on the floor spring.

- Q: Is spring steel manganese steel?
- Manganese steel and spring steel are the names produced under different classifications. The spring steel is classified from its use, and manganese steel is classified from its constituents. Spring steel also contains manganese, which is a kind of manganese steel.
- Q: Hydraulic diagram of the one-way valve has two kinds of drawing, with a spring, without a spring, what is the difference between automatic reset function is not? Without a spring, it will not be repeated
- Certain large diameter one-way valves have no springs, and steel balls rely on gravity return. These valves usually require vertical mounting.In fact, in the oil flow driven, the ball will always reset, no spring one-way valve can also be closed. Only the closing action has hysteresis, better than the spring back reliable.
- Q: What is spring pressure and height?
- Press the compression spring to the point where each circle is tight. Press it and press it high
- Q: Can springs be used for support?
- One point, the spring you choose to bear the force is higher than the gear weight pressure, if higher than, then the spring to withstand 0. Unless the heat changes, the spring steel is denatured. Long periods of rust change can also make a difference. Deal with the above two points. 0 pressure spring does not exist short pressure
- Q: What kind of material does spring have?
- In some specific occasions, such as pH and humidity, we often use stainless steel to make springs.The material of the die spring is usually made of chrome alloy steel. Chromium alloy spring steel has the characteristics of high temperature resistance, great rigidity and long service life.
- Q: How should we choose the spring material?
- Whether the spring is good or not is of great importance to the choice of the spring material. In general, selection of spring material, should take into account the load properties, spring force, various factors should be size, working conditions and price, etc.. Specific can follow the following principles: 1) in determining the shape and size of spring material, should be preferred dimensions behind national standards or standard stipulated, try to avoid using non standard materials. Although the spiral spring square or rectangular cross section material, the elastic deformation can be higher than, can make the small volume of the spring, for spring, in small space or under impact load but because of square or rectangular section material shortage, the price is higher, and the spring forming is difficult, so should be avoided. Ring section spring material diameter series see table 3-9. 2) the degree of cold plastic deformation of cold drawn spring materials is high. Most finished steel wires have reached the required mechanical properties when they leave the factory. The surface quality of the steel wire is high, and the manufacturing process of the spring is simple. For springs of medium or small spring or high fatigue life, the cold spring or cold drawn spring or steel wire or strip shall be selected as far as possible. Carbon spring steel wire (group I, group II, group II A, dish group) and important uses of 65Mn spring steel wire during the cold drawing process caused in large residual stress, the larger the size change after low temperature tempering, and thus affect the dimensional accuracy of the spring. For the bending radius of smaller tension and torsion spring, as well as smaller steel wire compression...
- Q: Is the car short spring good?
- Hello: no modification is recommended! Although the spring shortening can reduce the height of the body to make the car appear more sporty, it can also reduce partial roll during cornering. But it does more harm than good. Below say, change the disadvantage of short reed. First of all, lowering the body will affect the passing, and the over speed belt is easy to drag the chassis. Another major drawback is that the full set of shock absorbers consists of a helical spring and a hydraulic cylinder shock absorber.
- Q: How to process Spring Steel
- Spring steel must pay special attention to decarburization and surface quality during rolling. When the steel surface is seriously decarburization, the fatigue limit of steel will be significantly reduced. For high silicon spring steels, such as 70Si3MnA, caution shall be taken to avoid graphitization. Therefore, stop rolling temperature in hot working time should not be too low (less than 850 DEG C), avoid in the temperature range of graphite is easy to form (650 to 800 DEG C) in the long residence time.
- Q: In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position"
- In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position"
- Q: The glass door spring is broken. How much would it cost to change it?
- Replace the ground spring, the price of the earth spring itself, but also part of the labor costs, after all, it is very expensive. Land springs in general, if used in general, that is, about 150, but with labor costs, usually around 80. Specific prices should be based on your actual situation, you and the master speak.
