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
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 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:Cold rolled coil spring spring and difference "
Coil is to burn the red, generally large diameter to coil
Q:What are the categories of springs?
A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and are restored to original shape after removal of external forces. Also made as a spring". Usually made of spring steel. The type of spring is complex and varied. According to the shape, there are mainly spiral spring, scroll spring, plate spring, special-shaped spring and so on.
Q:Is spring steel manganese steel?
The most important characteristic of manganese steel is that it can be worked hard under strong impact and extrusion, and its wear resistance is improved, mainly by its working hardening.Spring steel mainly requires large elasticity, high yield strength, and can withstand repeated load without breaking. Spring steel only after heat treatment (quenching + medium temperature tempering) can show its high elasticity, that is, after a certain load, does not occur permanent deformation. The content of Mn in spring steel is much lower than that of Mn in manganese steel.
Q:Stainless steel and spring steel hardness, who is hard?
You should say that the deformation resistance, spring steel generally high strength, large deformation resistance, generally speaking, stainless steel generally than spring steel deformation easier, and some varieties of stainless steel deformation resistance is also very large
Q:How to choose spring steel 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..
Q:What are the main functions of spring?
There are many kinds of spring, and the spring is mainly divided into four kinds: stretching spring, compression spring, torsion spring and bent spring. If in accordance with the spring shape and can be divided into helical springs, disc springs, ring spring, plate spring, spring etc.. The basic types of springs are listed in the table. Air springs.
Q:What is an independent bagged spring?
Independent bags, spring inner bladder, column spring, non-woven fabric wrapped, unique ultra quiet design, for you and your sleeping partner to create a warm sleep atmosphere.Independent bagged spring bladder, designed and manufactured by leading domestic production line, fully conforms to the Qi curve formed when maintaining human body sleep. Straight cylindrical spring, non-woven separated, effectively avoid the metal liner due to friction also belongs to the voice with humanization ultra quiet design, to create a warm atmosphere for you to sleep, and when you sleep with the move will not give you his lying position caused by any vibration, so as to ensure the quality of your sleep. Straight cylinder liner using the circular shaped spring, with extraordinary comfort and elastic stability.
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
According to the conservation of mechanical energy, the object should be a free fall motion at the upper end of the spring
