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

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: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
General one-way valve is spring to reset, as for drawing may be the standard of drawing is not the same. As long as no oil passes, it closes.
Q:The glass door spring is broken. How much would it cost to change it?
The ground springs are not expensive, they are artificially expensive. It won't cost more than 300 yuan, depending on where you are. For example, 180-220 people will do it in the county. In the township, then you do not want to do aluminum alloy will not exceed 200
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:Displacement problems in a spring oscillator
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:Is spring steel manganese steel?
With wings are not necessarily the "angel", also may be "bird". Steel not containing Mn elements is called manganese steel. Manganese steel refers to those with high strength steel, mainly used for impact, friction and extrusion, mainly wear and tear.
Q:Stainless steel and spring steel hardness, who is hard?
To sell the spring steel where seen relatively hard two pliers are very difficult to open
Q:The glass door spring is generally guaranteed for several years
,expect a warranty to ensure the quality is not very reliable.
Q:What are the main functions of spring?
Absorb vibration and impact energy, such as damping springs in various kinds of vehicles and springs of various buffers
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:Physics high school. Why does a spring fall to the lowest point and the acceleration a must be greater than the acceleration of gravity g ah. Seek expert
For small spheres, the energy is conserved from the free fall to the ultimate spring compression equal to the maximum value of XMgX=0.5kX^2 (this formula is obtained by integration, do not know if you have no calculus)Calculate X=2mg/k, then the lowest point is the resultant force of the ball is kX-mg=2mg-mg=mg, in the direction of acceleration, the size is exactly equal to GIf the ball is considered to fall from high, then the energy conservation before it converts the energy of the potential energy into springs is naturally more, and the acceleration of the lowest point ball is greater than g
