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

 

      Hydraulic Door Closer /Floor Spring/Floor Hinge for Glass Door FS-71 

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
The simplified method of drawing without springs is the same
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
Is the map tilted?.Look at the picture. It means that a naturally stretched spring is placed vertically and then put a mass of m at zero initial speed.If dropped to the lowest point, the speed of the object v=0, object by the acceleration of gravity g down, if not spring to give it an g greater than or equal to the acceleration, the object will continue to fall, do not conform to the original intention of "low".So the acceleration inside the spring must be greater than or equal to g.
Q:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching
Spring: Spring quenching hardening is the steel is heated to the critical temperature of Ac, or Ac: the above heat preservation time, the austenite with greater than the critical cooling rate of rapid cooling, so as to obtain the heat treatment method of martensite.
Q:Buffer spring buffer for automobile
Next, put a soapy water or lubricant on the loose coil spring. Then, insert a strong buffer of soap, water or lubricant into the loose spiral spring gap, and then release the car body after confirming it.Finally, the distance between the damping springs is a matter of concern for mounting the shock absorber. The distance between the springs is equal to the length of the shock absorber. If it is more difficult to squeeze by hand, loosen the screw of the shock absorber, and let the damping spring relax 2 - 3 centimeters.
Q:The shop glass spring door is too tight, how to adjust?
If it is the glass door of the ground spring, then call the installation worker to loosen it.
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:Cold rolled coil spring spring and difference "
The main production process is different, the compression spring as an example:The typical process of coil spring: blanking - end processing (rolled or forged flat) - heating - - - quenching - tempering spring roll grinding end - compressor (load - Test), shot peening (cleaning) - coating.Cold roll spring does not require heat treatment of material roll, point line process: rolling, annealing, stress to both ends of the surface grinding, (blast), (the whole school), (BKS), standing or forcing treatment, surface inspection and treatment.Coil spring is mainly used for rolling large spring, heating easily after twisting forming, springback is smaller, molding after quenching and tempering treatment.The cold coiling spring is directly coiled with spring steel wire, and the resilience is greater, and the winding tools need to consider the springback compensation amount and roll into the direct tempering process.
Q:The glass door spring is generally guaranteed for several years
,expect a warranty to ensure the quality is not very reliable.
Q:Want to practice how to use pectoral muscle spring expander
If your strength is not enough, a chest start even more difficult, not easy to do it.It is recommended that you should not rely solely on the chest muscle training, according to their ability, to start from the first push ups. Practice to a certain extent to practice chest.If possible, the best way is to do chest push arms parallel flexion, but more difficult.The best chest group 20, a group is appropriate.
Q:What is spring pressure and height?
Press the compression spring to the point where each circle is tightPress height = = (total coil number -0.5) * steel wire diameter
