Description

Technical Field

[0001] The utility model relates to the technical field of buffers, and specifically relates to an adjustable-speed oil buffer. Background Art

[0002] The oil buffer can effectively stop a moving object in a balanced manner. Generally, the oil buffer is fixed and non-adjustable, and its specific performance parameters have been determined during the design and manufacturing process, and these parameters will not change during the product life cycle; the fixed non-adjustable oil buffers on the market usually can also meet the buffering requirements. During the working process, the oil buffer converts the kinetic energy generated by the object's movement into heat energy and dissipates it in the air, thereby eliminating impacts, vibrations, and effectively reducing noise; however, the situations where impacts occur are often diverse. The fixed non-adjustable oil buffer can only meet one current working condition, which is relatively single. The disadvantage of this buffer is its low flexibility and inability to adapt to equipment with large differences in working condition parameters; if the operating conditions or loads of the equipment change, it may be necessary to replace different types of buffers, which increases the maintenance and replacement costs.

[0003] In view of the above existing problems, an adjustable-speed oil buffer is developed, which can be applicable to equipment with large differences in working condition parameters. Summary of the Utility Model
