Precautions for use

  1. Please control the stroke of the air spring within the maximum stroke range allowed by the product. For specific parameter information, please refer to the product catalog.
  2. If the action height of the air spring exceeds the maximum height, the upper and lower panels will be separated from the rubber body, and the internal air will leak rapidly, which is very dangerous. Therefore, some blocks must be installed.
  3. Please control the commonly used maximum internal pressure of the air spring within the internal pressure range allowed by the product (see the product performance table for specific information). To ensure long-term use, it is recommended to control the commonly used internal pressure within 0.6MPa. In addition, for self-sealing air springs, when the internal pressure is too low, it may not be able to maintain sufficient sealing performance. Therefore, please control the internal pressure to more than 0.2MPa as much as possible.
  4. Please pay attention to avoid the air spring from colliding with other objects during the action. For specific data, please refer to the minimum installation space value of the product.
  5. If the air spring may be scratched due to contact with metal sheets, etc., it must be covered with iron plates to prevent damage to the air spring.
  6. Air springs adhering to oil will affect durability, please be careful to avoid it.
  7. Please control the ambient temperature of the air spring within the range of -40℃~80℃, otherwise the durability of the air spring will be reduced. If the working temperature exceeds the recommended operating temperature, please communicate with Eurasia Rubber Company before use.
  8. If the volume of the auxiliary gas tank is too large, please handle it in accordance with relevant regulations and pay attention.
  9. When the air spring is extended to near the maximum height, do not release the internal pressure quickly. Otherwise, the rubber membrane may be concave and the waist ring may fall off. Therefore, the minimum internal pressure must be maintained at 1kgf/cm2 at this time.
  10. When applying internal pressure to the air spring, be sure to install it on the machine before doing so. If the internal pressure is applied in a free state, the upper and lower panels may slip or even fall off, which is very dangerous.
  11. If the air spring is compressed to near the minimum height and the internal pressure is released for a long time, it will deform, so please pay attention.

Storage

  1. When storing the air spring, please store it in a low-temperature dark place with poor ventilation as much as possible, and avoid direct sunlight.
  2. Avoid oil and chemicals on the air spring. If left unattended after being stained, the durability may be reduced due to the reduction of the physical properties of the rubber.
  3. The wall thickness of the air spring is relatively thin, about 5mm. Please be careful to avoid scratches, etc.
  4. It is ideal to store the air spring in a free state.
  5. Do not place it in a place with a temperature above 50°C.

Maintenance and inspection

For air springs, daily inspection and safe use must be carried out. If abnormalities are found after inspection, they must be replaced with new ones immediately.

  1. Before using the air spring, it is necessary to confirm whether the upper and lower panels and waist rings are installed correctly, especially the waist ring. If internal pressure is applied to the rubber membrane when the waist ring is offset or detached, the rubber membrane will rupture.
  2. If impurities, oils, chemicals, etc. adhere to the air spring, be sure to clean them.
  3. If lubricating oil enters the inside of the air spring, it must be wiped frequently and the inside of the air spring must be washed regularly.
  4. Please confirm whether the appropriate pressure can be provided during use, especially in many cases, the piping system may be abnormal, please pay attention.
  5. Please replace the air spring in the following cases.
  • The outer rubber layer has cracks, scratches, and wear that can reach the reinforcing cord layer.
  • The air spring is abnormally deformed or expanded. Even if there is no external damage, air will accumulate inside the air spring, resulting in separation.
  • The rubber surface expands or cracks due to oil, chemicals, heat, etc.
  1. If the upper and lower panels and waist rings are corroded, the air spring will be scratched. Therefore, the corroded parts must be replaced.
