Locking struts Function:

The working principle of locking strut is based on the cooperative mechanism of gas energy storage and mechanical locking. Its core is composed of a sealed cylinder filled with high-pressure nitrogen and a telescopic piston rod. When the external force is applied, the piston compresses the nitrogen to store energy, and the gas expands to provide stable support force when released. The key innovation is the locking feature: through the built-in mechanical buckle, hydraulic valve or electromagnetic device, the user can trigger the lock in any position, forcing the fixed piston rod stroke, forming a rigid support. In the locked state, the system can withstand static load and resist vibration or unexpected pressure changes to prevent the equipment from sinking or losing control. After unlocking, the dynamic adjustment ability is immediately restored to realize smooth lifting. This kind of gas strut mechanism has both energy buffering and precise positioning characteristics, and is widely used in automobile tail doors, medical beds, industrial manipulators and other scenarios.

Lockable gas pressurized spring Features:

Lockable gas pressurized spring consist of a gas pressurized tube together with a piston rod and piston.

The piston is fitted with a valve that is actuated by the release pin. When the valve is shut, the gas spring does not move, thus providing locking in the desired position.

Industrial locking gas springs are designed for harsh industrial applications. They combine high load performance with intelligent lock-in functions. This gas strut mechanism adopt reinforced cylinders and corrosion resistant materials to withstand hundreds to thousands of dynamic/static loads, adapt to high temperature, dust and corrosive environment.

Safety Lockable Gas Struts Advantages:

Lockable spring 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 lockable spring?

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

3. Should lockable 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.
