       Hydraulic Floor Hinge/ Door Closer/Floor Spring for Glass Door/Floor Hinge for Glass Door FS-222

     

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:How to process Spring Steel
After the spring is made, shot peening can produce residual compressive stress on the surface of the spring so as to offset part of the working stress on the surface layer and restrain the formation of surface cracks, which can significantly improve the fatigue limit of the 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:How to distinguish between spring steel and stainless steel
Mainly depends on the performance of spring steel, good elasticity, stainless steel toughness. The color should be slightly white stainless steel. Spring steel is easy to rust, with a little salt a day you can see the stainless steel does not rust.
Q:How should we choose the spring material?
The selection of spring materials shall be determined according to the nature of the load, stress state, stress magnitude, working temperature, working environment and service period of the spring.
Q:What are the categories of springs?
The tension spring is a coil spring that bears axial tension. In the case of no load, the coil between the coil and the coil is generally tight and without gaps.
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?
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:The glass door spring is generally guaranteed for several years
but once you change the maintenance fees are higher than the artificial spring spring price itself
Q:What are the main functions of spring?
Control the movement of a machine, such as a spring that controls the opening and closing of a cylinder valve in an internal-combustion engine, and a control spring in the clutch
Q:What is flat steel? Plain carbon flat steel? Spring flat steel
Flat steel, also called flat steel strip, is a long thin steel with a rectangular cross-section. According to the production process, it can be divided into hot rolled flat steel strip, fine shearing flat steel belt and cold drawn flat steel belt.Ordinary carbon flat steel - the component is ordinary carbon structural steel, suitable for wide range.Flat spring - flat steel used for making spring plates of automobiles, containing manganese.
