Gas spring installation instructions and precautions:

Gas spring piston rod to the down position to install, no flip, which can reduce friction and ensure the best quality and buffer damping performance. Determine whether the gas spring pivot position is guaranteed to work correctly, when the axis of the spring off the gas component to be moved off center.
No transverse force gas spring. Handrails shall not be used. To ensure the reliability of sealing and shall not damage the surface of the piston rod is forbidden to paint and chemical substances applied to the piston rod. Strictly forbidden to install gas spring and then spray paint in the desired position.
Gas spring for the high-pressure products, non-random analysis, fire and hit touch. Gas spring piston rod to the left is strictly prohibited. To adjust the joint position, can only turn right. Ambient temperature: -35 - +60 ℃ (specific manufacturing 80 ℃) Installation connection points should be flexible rotation, can not have jamming phenomenon. Select size should be reasonable, the size of force to the right, the piston rod stroke size to 10 mm left margin.

A - Rod Design stroke (mm)
B - gas spring extension length (mm)
B1 - gas spring compression length (mm)
D - gas spring cylinder length (mm)
E - gas spring both ends of the connector length (mm) (center to install the end connector installation) the minimum force required to stretch the value of force formula
Determination of F1
F1 = kGL / bn where the minimum extension force F1, Unit N
G = door weight, unit kg
L = distance from the center of gravity to the rotation center, unit mm
b = gas spring rod extension, the effective moment arm, unit mm
n = number of Gas Spring
k = safety factor, usually 11
P = gas spring is installed on the door, about 1/3L from the rotation center
G = 30kg L = 400mm n = 2 b = 200mm F1 = 30 × 400 × 11 / (200 × 2) = 330N

Gas spring piston rod stroke (A) and stretching the length of (B) Determination

1, piston rod stroke (A) the actual use is generally +10 mm stroke
2 cylinder length (D) generally B-B1 + f when B-B1 <150mm when, f> 40mm when B-B1 in the 150mm ~ 200mm between the time, f> 50mm when B-B1 in the 200mm ~ 300mm when, f > 60mm where Note: f-oriented factors
3, stretching the length of B = A + D +2 E where:
A - Rod itineraries
B - stretching the length of gas spring
B1 - the length of gas spring compression
D - the length of gas spring cylinder
E - gas spring both ends of the connector length (center to install the end connector installed)
