gas spring

Function:

Mechanical lock structure: the lockable gas fpring features a special locking structure, usually consisting of an external support tube or similar mechanism. When locking is required, the mechanical structure acts to limit the movement of the piston rod and hold it in place.

Valve control principle: the rigid locking gas strut through the valve mechanism to control the flow of gas, lock and unlock functions. When in the unlocked state, the gas can flow relatively freely in the pressure cylinder, at this time the piston rod can normally extend or retract to adapt to different use requirements; when the need to lock, the valve will be closed or switched, it blocks the flow of gas, thereby limiting the movement of the piston and keeping the piston rod in its current position.

Rigid Locking Gas Strut Features:

The rigid locking gas strut allows the stroke to stop at any position. It is mostly used in tables, beds, tables, chairs, paint lamps and other places where the angle and height need to be adjusted. According to the locking force, it can be divided into elastic locking and rigid locking. Rigid locking can be divided into compression locking and tension locking according to the different locking directions.

Rigid Locking Gas Strut Advantages:

By actuating the release pin, the piston rod of the lockable gas spring can be adjusted in every desired position throughout its stroke. Depending on the forces present in your application, we can rationally fit your lockable gas springs to different load limits.

FAQ:

1. What are JUTENG gas springs filled with?

Only nitrogen is used as the pressure medium in JUTENG gas springs. About 75% of the air we breath consists of this gas. Nitrogen is absolutely safe and harmless to health. In addition, nitrogen does not burn. On the contrary, nitrogen is used in the chemical industry to prevent and extinguish fires. In addition, every JUTENG pneumatic spring contains flame-retardant oil to lubricate the seals and to achieve certain functions, such as damping or rigid locking.

2. How high is the pressure in a gas spring?

The filling pressure of JUTENG gas springs depends on the extension force and the geometry and is between 5N and 3000N.

3. Should gas spring be installed with the piston rod facing up or down?

In general, gas springs should be installed with the piston rod facing down to ensure the piston rod seal is lubricated and to reduce the permeation of nitrogen through the seal. However, the opposite installation may be necessary in some special cases, for example if the gas spring requires a very specific damping characteristic. In such cases, the lubrication of the piston rod seal must be ensured by special measures (space mat).

4. What is "F1" force?

The "F1 force" is the designed force of gas springs. This is measured when the piston rod of the gas spring is extended to 5 mm. It should be noted that the measured point of a significantly shorter position is approached with a defined speed and the value of the "F1 force" is read only about 3 seconds after the measurement devices comes to a standstill. The measurement must take place at 20°C gas spring and room temperature.

5. Does the force of the gas spring change when displacing the piston rod?

Yes. The inner volume of the gas spring is closed to the outside. This means that the filled gas volume can only occupy the free space in the pressure pipe that is not needed for components or oil. By pushing the piston rod in, this free space [V] is reduced by the inserted piston rod volume. Because the same gas volume has a smaller volume available, the pressure [p] in the gas spring increases.

6. Can gas springs be repaired?

No. All gas springs and dampers are by a plastic deformation of the external pipes during production. This makes it impossible to open the gas spring to replace individual components without destroying it.

7. How long can the gas springs be stored?

The storage of gas springs has no negative consequences on their function if it is ensured that the piston rods point down and no dirt accumulates on the piston rod. If gas springs are not actuated for a long time, they only have a slightly increased amount of friction during the first retraction. However, this effect is equalized after the first actuation and the gas spring then again exhibits the usual friction values.

8. Does the temperature affect the function of gas springs?

Yes. However, three temperatures ranges must be distinguished between. Between -40°C and +80°C (operating range), the temperature only affects the pressure of the gas in the gas spring.

The temperature has an additional effect on the damping behavior of the gas springs. The temperature increase makes the oil be less viscous, which reduces the oil's resistance to the flow of the piston. This results in less damping. Likewise, the damping increases with a lowering temperature.
