As urban industrial development progresses, the replacement of thermal pipelines and petrochemical pipelines is increasingly necessary, especially in recent years with the emergence of many long-distance compensating pipelines and three-dimensional pipelines. These pipelines require a significant number of support brackets during installation, leading to high construction costs. Particularly in space networks, the installation of fixed brackets is extremely challenging, and in some cases, impossible, severely impacting the design and development of the pipeline network.
Maintenance-Free and Superior Sealing Performance: Both the maintenance-free rotary compensator, rotary compensator, and sleeve compensator utilize mechanical seals, but their effects vary due to their different operational methods. The sleeve compensator experiences significant wear on the sealing surface due to its axial movement, and the rotary compensator is prone to leakage due to its inability to compensate for wear gaps. The maintenance-free rotary compensator operates with an inner and outer sleeve that rotate relatively at a small angle, resulting in minimal wear on the sealing material. In case of minor wear on the packing, the tension from the compression spring provides compensation; when the wear exceeds the spring tension compensation, simply tightening the screw on the compression flange is required. The operation has no limit in terms of the number of cycles, ensuring no leakage, thus significantly enhancing the economic benefits for both the gas supply and utility units. The product can compensate 5,000 times without leakage at a pressure of 7.5MPa, demonstrating superior sealing performance.
The maintenance-free rotating compensator, by using the inner tube and reducer with the same diameter, ensures smooth and unobstructed flow, thus solving the aforementioned issues. Certain similar products, due to the use of reducers, create vortices in the medium as a result of the diameter change during operation, leading to flow resistance and significant pressure loss, as well as reduced flow speed.
