gas spring

Function:

The structure of the controllable gas spring mainly consists of a gas cylinder, a piston, a piston rod, a spring, a sealing ring, an air cushion, a pressure sensor, a controller, etc. Among them, the air cylinder has a cylindrical structure, usually made of aluminum alloy, and has smooth internal processing to ensure the flexibility of the piston.

Features:

Lockable Gas springs 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.

Advantages:

In the aviation field, adjustable force gas spring are widely used in aircraft landing gear, shock absorption systems, zoom doors, protective shells and other parts. Due to its lightweight, high pressure resistance, corrosion resistance and other characteristics, it greatly improves the operating efficiency and safety of the aircraft.

Medical bed

Lift table

Office chair

Electric wheelchair

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.
