gas spring

heavy duty gas damper Function:

Compression gas spring is also called free best gas struts and support rod. Apply to hydraulic gas spring for bed,heavy duty gas damper.The common model is: YQ type compression gas spring. It mainly plays a supporting role. Using inert high-pressure gas as the energy storage medium, it is an actuator that does not require external energy and can be used instead of traditional cylindrical coil springs.

gas struts Features:

Heavy duty gas dampers are designed for high-load conditions. The heavy duty gas damper internal structure is optimized, using high-strength materials such as special alloy cylinder blocks and piston rods, which can carry tons of weight. This heavy duty gas damper is widely used in industry, large machinery and high-load construction facilities, such as heavy truck tail door support.

Heavy duty gas dampers has good cushioning and shock absorption performance. By means of internal high-pressure gas and throttling device, it can effectively absorb vibration, slow down the speed of movement, protect precision instruments, and help cranes to lift. Our Heavy duty gas dampers Can accurately control the speed, according to the demand to adjust the load lifting speed. High manufacturing precision, good sealing, special surface treatment, durable and reliable, suitable for harsh environments. Various installation methods, horizontal, vertical, tilt can be connected through pins, flanges and so on, versatility, adapt to different equipment and space.

Hood support

Tool box lid support

Trolley lid support

Aircraft luggage compartment cover

Parameters:

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.
