The up and down limit of Industrial air spring, we maybe not know how important it has
Although the installation of equipment design, process production characteristics are as far as possible to the direction of human development, but in actual production, the work environment is still far more than imagined in the event of failure, experienced season workers can Losses are minimized, including personnel safety, equipment damage, cargo protection, and energy waste.
In order to cope with the abnormal situation caused by the sudden situation of the air spring damage caused by the air spring to improve the ability to deal with the failure of the air spring in the trip the highest and lowest position are set up a limited device, and retain a certain distance from the space.
The minimum height in the compressed state is always defined as slightly higher than the height of the balloon compression (the lowest height that can be lowered after the exhaust gas). If the balloon is in the above-mentioned deflated state for a long time, it may cause damage. Therefore, it is required to have a downward limit to prevent this from happening. There are two ways to set the lower limit of the air spring, one is the outer lower limit, which can be placed around the air spring a simple steel block, the limit height should be slightly higher than the minimum height of the high-mater air spring, for example: if No gas state to a minimum of 60, the minimum limit of the minimum should not be less than 65mm. The other is in the air spring working environment can not use the external limit of the case, the air inside the spring can also be set to an internal cushion block as the minimum limit of air spring limit.
2. the highest limit
Air spring in its longest distance from the location, will also set its length limit device, the purpose is to prevent the air spring in its length to a certain position when the eyes, and will not be due to excessive pull and damage, air spring, after all, Metal and rubber combination of products, if more than the length of the air spring limit, first of all, the air spring rubber balloon part of the tensile strength is not high for the long-term use of air springs will cause serious impact, greatly reducing the air spring Service life. Second, the above figure shows that the air spring rubber balloon and the air spring between the end of the cap was designed in the air spring by the tension, if the tension is too large, it is easy because the stress concentration makes the rubber balloon in the With the first cover of the end of the tear, directly damage the air spring.
At the same time, the upper limit also played a role in the rebound limit, the use of air spring in the process, if the direction of the air spring in the direction of no restrictions, then the air spring is likely due to excessive pull caused by the withdrawal or Direct pull off.
There are also many ways to set the upper limit of the air spring, and the usual means include chains, cables, and metal contact limits.
