Description

Technical Field

[0001] The utility model relates to the technical field of interface pipe fittings, and particularly relates to a shock isolation and anti - detachment transition pipe for an oil - free compressor interface. Background Technique

[0002] An oil - free compressor, also known as an oil - free air compressor, refers to a compressor that does not use lubricating oil in the compressor cylinder. Since no lubricating oil is used, the quality of the output air is high, without oil and other pollutants. It eliminates the steps of regularly replacing lubricating oil and cleaning the oil circuit, reducing the maintenance cost. By adopting advanced energy - saving technologies such as variable - frequency speed regulation and high - efficiency motors, it has a high energy efficiency ratio and does not produce waste oil, which is beneficial to environmental protection. Oil - free compressors are widely used in multiple industries due to their unique advantages and show good performance in terms of environmental protection and energy conservation.

[0003] The problems of oil - free compressor vibration may stem from multiple aspects. For dry - type oil - free air compressors, their noise and vibration mainly come from the meshing and friction of the screw profiles. If parameters such as the screw profile and screw clearance are not optimized, it may lead to increased friction and impact during meshing, thus generating vibration. Although oil - free compressors do not use lubricating oil, the lubrication condition of key components such as bearings is still important. For example, if the bearing oil inlet nozzle size is too small or blocked, it may result in insufficient lubricating oil volume, rising bearing temperature, and thus causing vibration. When the inlet oil temperature of the compressor exceeds the specified requirement and the cooling water volume is insufficient, it may cause high bearing temperature due to insufficient lubrication and cooling, resulting in vibration. Loose base fixing bolts will cause the base to loosen, thus generating vibration. This vibration usually shows non - linear vibration in the vertical direction, and the vibration frequency may contain high - order harmonics. Scratches, burrs on the shaft surface or poor material wear resistance may lead to severe imbalance of the compressor after long - term use, thus generating vibration. The collision and friction between static and moving parts due to the dimensional accuracy of parts or the thermal expansion of materials are also one of the reasons for generating vibration.

[0004] In the existing compressor system, especially for oil - free compressors, due to the vibration and impact generated during operation, the connection parts between the compressor and other equipment or pipelines are often loosened or detached, thus affecting the normal operation of the compressor and even causing equipment damage. Therefore, we provide a shock isolation and anti - detachment transition pipe for an oil - free compressor interface. Content of the Utility Model

[0005] The technical problem solved by the utility model is: in the existing compressor system, especially for oil - free compressors, due to the vibration and impact generated during operation, the connection parts between the compressor and other equipment or pipelines are often loosened or detached, thus affecting the normal operation of the compressor and even causing equipment damage.
