How does the chair lifts developed with gas spring lift support

/in /by
Choose the angle of the stand for the chair, so the rotation of the chair is normal. The development of the chair lift supported by pneumatic lift? We will explain briefly.

Mechanical support chair

In the early days, lifting and lowering was mechanical. They use threaded solid steel rods to support the back seat of the chair. When we need to adjust the height of the chair, when the chair is put down, fasten the bolts with the completed belt, and then adjust. Screw fixing height. Relatively simple, mechanically relatively simple, but we are not very easy. It takes more safety time to change the height, so the mechanical way is gradually eliminated.
On this basis, the hydraulic lift chair came into being for the plane layout and efficiency improvement.

Hydraulic support

According to the principle of hydraulic transmission, the lifting table of the display can be lifted by the hydraulic valve. But it improves the rod’s approach, and the grid troubles out the possibility of a mechanical display. Due to its hydraulic pressure, an oil leak occurs. High cost chairs that get dirty and dirty. Plus, multiple industry-installed switches are required to complete the height of the chair. Therefore, its conditioning effect is not very beautiful, therefore, its main assembly services such as hairdressing are not, decentralized conditioning. .

gas spring support chair

It is a rod lift chair that uses gas springs.
The spring can be stopped and locked in any position using the release mechanism. We can use completion. It enables easy operation and high control. applications and occasions. Chi is also popular in chairs, and there are many varieties to choose from.
Now the development of lift table technology will bring more convenience and convenience. .

Coding method on gas spring models

/in /by
We usually give a code on the gas spring models, which consist of numbers and letters. It requires us to know what they mean, and why suppliers mark them as such. That help us to get more details from gas spring models.
 
Peir gas spring works as industrial accessories. It offers the function of supporting, buffering, height and angle change. It consists of a steel cylinder with gas under pressure. And a rod that slides in and out of the cylinder through a sealing guide. It can also have control elements(for controlled ones) and end fittings

A coding method for some gas spring type

 
The code of gas spring model, in general, composes of the following important parts. They include type code, the diameter of the piston rod, the outer diameter of the cylinder, the stroke, the extension length, and the end fittings. Besides, the working method, the end joint fitting, and the small expansion force are all necessary iinformation.
 
Among them, you must know the code of gas spring type. The compression gas spring is YQ; SKQ stands for the height adjusted one and JKQ the angle adjusted one. The balance gas spring is PQ, and LQ stands for traction gas spring.
 
The regulations are as follows:
 
×××××/×× – ××× – ×××（×× – ××）×××
 
1. Various gas spring codes:
 
compress gas spring YQ,
 
height adjustable gas spring SKQ(KQ),
 
angle-adjustable gas spring JKQ,
 
balanced gas spring PQ,
 
traction gas spring LQ
 
2. The diameter of the piston rod(d), the outer diameter of the cylinder(D), the stroke(S). And the extension length (L) in mm, and the extension force in Newton (N).
 
3. Type code of joints(end fittings): single-core o type, double lug u type, single lug l type. spherical hinge type b, thread m type, taper s type.
 

Marking Example of Gas  Spring Models:

 
Description: compressed gas spring piston with 10mm rod diameter. The outer diameter of the cylinder is 22mm, with a 260mm stroke and an extension length 630mm. Rod end connector is integral, the end fitting is a ball hinge, tensile force Small 380N.
 
Marked as: YQ10/22-260-630(O-B)380

Instructions of attention in the use of rotary damper installation

/in /by

Rotary damper is of small size and delicate structure, so we must put some instructions to damper installation or use. We have to apply it properly and avoid mechanical damage. Please read attention notes carefully before rotary damper installation or use.

  1. Do ensure the installation strength of counterpart

In case of poor strength, your application may be broken and even cause personal injury. Please ensure the damper installation strength and torque are safe to support .

  1. Prohibit the use of a stop device

Do use the rotary damper within the available application range. Do not use dampers to stop other objects, or it may cause personal and mechanical injury accidents.

  1. Prohibit the use of axial overload

Axial overload can cause damage to the shaft so it reduce the life cycle of rotary damper.

  1. Do not exceed the max torque

If the application exceed the rated torque, oil leakage will happen and its life cycle goes down. Overload can damaged the damper shaft greatly. What’s worse, mechanical injury accidents will happen. So please use within the rated torque range.

  1. Avoid using beyond temperature range

The inner structure of rotary damper is very sensitive to temperature. In case of  extreme temperature beyond specified range, torque will become abnormal and cause leakage. Please use the rotary damper in the application temperature range.

  1. Use environmental attention

Please do not use rotary damper under vacuum or high pressure as it will probably cause mechanical damage.

  1. Do not litter the discarded damper

Waste oil in the the vane rotary damper can cause pollution to the environment. Instead we should deal with the discarded damper and its waste oil according to the regulation.

Small part plays a big role. Our rotary damper do helps to smooth motion. If we can use them properly, it will make bigger influence.

Gas spring mechanism

Firstly, according to gas spring mechanism(also called gas strut mechanism) ’s motion way, they can be divided into two types:
1. Compression gas spring

It cannot stop during the whole stroke, can only stop at the shortest and longest position. When it is in the free state, it is at its longest position;

Lockable gas spring

2. Self-locking gas spring

It is controlled by a switch. Self-locking gas spring can be stopped at any position in the stroke. When turn on the switch, its performance is the same as compression gas spring. When the switch is turned off, the self-locking gas spring can be stopped in any position. Its self-locking force can reach 8-10 times.

Further more, according to self-locking gas spring mechanism ’s  characteristics, they can be divided into two types:

1. Elastic self-locking

The self-locking force is about 3-5 times.  After turn off the switch, the gas spring can have a simple cushion.
2. Rigid self-locking

The self-locking force reaches 8-10 times. After turn off he switch, the gas spring can stop immediately without buffering.

According to gas spring application requirement, the self-locking gas spring can be divided into six types:

  1. Extension direction rigid self-lockinggas spring;
  2. Compression direction elastic self-lockinggas spring;
  3. Extension direction elastic self-lockinggas spring;
  4. Compression direction rigid self-locking;
  5. Two-way elastic self-locking;
  6. Two-way rigid self-locking.

What is gas spring dampers?

Gas spring hinge( also called gas struts)  is mainly for following functions:

  1. Buffers load impact in machinery and equipment
  2. Avoids collision damage and eliminate noise
  3. Increases circulation speed
  4. Improves user experience.

It is widely used in industries, like automation, robotics, furniture, fitness equipment, automobiles, and medical equipment. As we all know, gas struts with its functions as support, cushioning, braking, height adjustment angle and degree adjustment.

Gas springs manufacturing procedure is as following:

  1. Fill a closed cylinder with inert gas or a mixture of oil and gas with a certain pressure difference from the outside atmospheric pressure.
  2. Use the pressure difference acting on the cross section of the piston rod to complete the free movement.Compressed gas pring yq12The biggest difference between gas spring and general mechanical spring:
    1. For a general mechanical spring, its force changes greatly with the movement, while the force value of it remains basically unchanged during the whole movement.
    2. For general steel springs, with a certain external dimension, there is only one force.But for gas spring hinge, the one of the same size can be made into different forces.Peir In. | LinkedIn
