Nov 15,  · This video demonstrates increasing the newton pressure of a gas whole process takes about a minute. How to Install Your Gas Strut When you purchase your gas strut, we recommend using those with ball joints that will help to alleviate uneven wearing of the piston rod and the seals. Place the cup of the baring over the ball joint and fit with the piston rod down within 60 degrees to the vertical.

Gas Struts are most steuts used to assist raising and lowering of hinged doors, such as on a stryts canopy or overhead cabinets. They are also used in many other applications such how to re gas struts in office and transportation equipment.

Co-Mac's gas strut length is measured from the centre of the ball joint at each end. If you want to replace an existing gas strut, measure the length of your strut from hos centre of each ball joint. If your gas strut does not have ball joints, measure the length of the gas strut with no end attachments.

If you cannot find a gas strut with exactly the same size, find the closest size up or contact us ask comac. There should always be 2 gas gaa installed per door. This ensures that equal weight is on each end of the door when opening. Having only one gas strut on a te can yas or damage your hinge.

Because of this it is also important to install 2 gas struts with the same length and pressure on both ends of the door. Hw means that both ends of the door open to the same height. Warning: Gas sttruts can be dangerous, please take all health and safety concerns and precautions into account when installing the gas struts. Ho you have found the gas strut in our range that will fit your door, it is time to install it.

Using the provided Hex Key, quickly open and shut the valve at the top of the strut. One open and shut equals one pulse. We recommend releasing gas in short sharp pulses. Remember to do the same amount of pulses on each gas strut on your door.

Test regularly to see if the struts have reached the right pressure. To avoid releasing to much gas we recommend adding a little weight to your door when adjusting the struts. If too much gas has been released from the struts, they will be too weak to open your door.

If this happens you will have to send them back to Co-Mac to be re-gassed. We are only able to Re-Gas Gas Struts from our range. If your gas strut will not compress you need to let more gas out of it. The pressure is too high for how to remove ear wax buildup at home strut to compress under the weight of the door.

This usually happens if wind has wrenched the door open, forcing the piston of the strut past the safety ring and jamming the strut in the open position. If this has happened you will need new struts as overextended struts are not safe to use.

Mounting Points

For the gas strut repair, the strut must be removed from the host equipment and sent to our workshop for a free inspection. We will then advise you if a re-gas will be successful or economical. The struts are tested and gassed on the day they are received and shipped back using a . Feb 24,  · Discussion Starter • #1 • Mar 14, I have 4 struts to fix or replace. I am assuming if I can hold them stretched and get them under enough pressure, that they will refill. (Thinking of 3/4" plumbers tube with compression end caps and a car tyre valve embedded in one of them) Put the strut in, close the joint, turn on the air, etc. The gas struts should now be holding the weight of your door. Adjust the gas struts to suit the weight of your door. Co-Mac’s gas struts are adjustable, allowing you to let the pressure down until it suits the weight of your door. Using the provided Hex Key, quickly open and shut the valve at the top of the strut.

Details will not be shared with third parties. As the names suggest, the fixed mounting point remains fixed, whereas the moving mounting point rotates through an arc as the application opens and closes.

This provides an extremely rough guide as to where to place a strut, but if this is developed further it will also give an indication of the size of the required product. This type of mounting can be identified by the fact that the end at the lowest point when closed, remains in its lowest position when fully open.

It can also be identified by the moving mounting point being located closer to the hinge than the fixed mounting point. Unless a means is utilised to lubricate the rod, then the strut should always be mounted rod down to ensure proper lubrication of the main seal. The main drawback of this mounting position is the additional strength required in the application being lifted, particularly the hinge; this is due to increased cantilever of the lid from the support provided by the strut.

The major advantage with this type of mounting and rod down orientation is that it provides consistent damping at the end of the stroke. This is due to oil always being at the bottom of the tube; thus, damping will always occur at the same point in the lift cycle.

This type of mounting can be identified by the end at the lowest point of the strut when closed, rotates to the highest point when fully open. It can also be identified by the moving mounting point being located further away from the hinge than the fixed mounting point. Unless a means is utilised to lubricate the rod then it is advised to mount rod down, ensuring proper lubrication of the main seal in the closed position.

The main drawback of this mounting position is the lack of damping control throughout the stroke. At the start of the stroke, the oil is at the bottom around the main seal. As the horizontal position is passed, the oil begins to run down the tube towards the tube end. Along this point it will meet the piston moving up through the tube. When the piston meets the oil, extension will be slowed until the oil has passed through.

At this point, the extension speed will increase and will reach the end of the stroke with no damping. The advantage of this design is that it places less strain on the hinges than the push up design. Crossover is the point at which the strut takes over the lifting action or gravity takes over to close. In practice, this will vary by several degrees between opening and closing, due to factors such as friction of the internal components of the spring, hinges and end connectors.

Self-rise is the angle at which the lid is lifted without any assistance from the operator. Similarly, self-close is the angle at which the lid will close without any assistance. This behaviour is unpredictable to the operator and can allow the lid to open without any warning, in instances where the P1 force increases above nominal due to elevated ambient temperatures, for example.

Temperature not only affects the output force, but also the handling forces. Gas Spring and gas strut installation handling forces chart. Crossover at 20 degrees Celsius. Angle of opening Degrees vs. Crossover at 65 degrees Celsius.

This behaviour is unpredictable to the operator, in some cases proving dangerous. It is also evident that handling effort to close the application increases. Should dampers be mounted rod up or rod down? The answer to this is dependent on whether the damper is a compression or extension damper; each having specific orientations and should be mounted as follows:. Extension damper and compression damper side by side comparison.

Lubrication of the main seal is not a problem due to the high volume of oil used in the damper. Positioning the moving mounting point so that it creates an over-centre condition when the lid is closed will aid in reducing instant opening of the lid. The figure below highlights two examples; one of a position which will lead to instant lift on the left and one which is over-centre and will reduce the potential of instant lift on the right.
