(1) High safety performance: maintenance free rotation Compensator The structure is reasonable, the thickness of the material used is equal to or greater than the thickness of the base material of the heat supply network pipe, and it can withstand the destructive force of water hammer during operation; the product can withstand the temperature and pressure resistance of the product, which can meet the engineering requirements, and can withstand the destructive stress caused by the sudden change of the temperature and pressure of the pipeline, and has high safety performance.                                                         

(2) Long product life: the service life of maintenance free rotary compensator can reach more than 20 years, which exceeds the service life of heat supply network pipeline. It has been tested and confirmed by relevant departments (heat supply network pipeline ~ standard 15 years) Corrugated compensator Life expectancy has been doubled.
(3) Reasonable structure: due to the special structure of the maintenance free rotary compensator, its internal pressure thrust has been eliminated in the product structure, so that the original material stress has evolved into mechanical dynamics. N groups of springs are installed above the packing compression flange (n is a constant, and its number is determined according to the size of the diameter), so that the sealing packing can be compressed automatically in case of wear and loss; rollers are machined between the inner and outer sleeves to make the product work freely and ensure the concentricity and stability of the product.
(4) Large amount of compensation: the compensation amount of maintenance free rotary compensator can reach 1800mm (other types of compensators ≤ 300 mm), and no product can be comparable with it; after being successfully installed in the Φ 480 heat supply network pipeline, the compensation distance is more than 500m, and it is generally suitable to use a group of 200-500m, depending on the site topography The transmission pipeline of medium can be used in long distance.
(5) maintenance free and superior sealing performance: maintenance free rotary compensator, rotary compensator and sleeve compensator all adopt mechanical seals, and the effects are different due to different operation modes. Due to the axial movement of sleeve compensator, the wear of sealing surface is large, and the rotary compensator is easy to leak due to the failure to compensate the wear clearance. The working principle of the maintenance free rotary compensator is that the inner and outer sleeves rotate relatively and the rotation angle is small, which causes less wear on the sealing material. When a small amount of packing wear occurs, compensation is made by the tension of the compression spring; when the wear amount exceeds the compensation amount of spring tension, just pull the nut above the spring compression flange. There is no limit of operation times and no leakage, which greatly improves the economic benefits of gas supply units and gas users. The product can compensate 5000 times under the pressure of 7.5Mpa without leakage and has excellent sealing effect.
(6) Due to the large amount of compensation and no thrust of maintenance free rotary compensator, the number of compensators and civil engineering scale are greatly saved, the total project investment is saved by 20%, and the economic benefits are considerable.
(7) The design is convenient; the use of maintenance free rotary compensator, due to the medium, flow rate, temperature, pressure and other technical parameters caused by the change of stress changes, without additional calculation, only need to calculate the friction force. And the layout is diversified and the design is much simpler.
(8) Under the standard parameters, compared with the traditional compensation method, the pressure drop of the pipeline is reduced, the medium is smooth, and the gas transmission distance of the pipeline is extended by 20% - 30%, which greatly improves the heating radius and the economic benefit of the heating unit.
(9) The installation mode and type are diversified; the maintenance free rotary compensator is suitable for various directions (bending, straight running and right angle) on overhead pipelines.
(10) The installation and construction are convenient; the installation of maintenance free rotary compensator does not need the complex process of cold drawing and pre tightening, and butt welding is OK.
Maintenance free rotary compensator is a new type of compensator for heat supply pipeline introduced by Shanghai Luoying product R & D staff after years of development, practice and efforts. It is evolved from the structure of sleeve compensator combined with the principle of rotary joint, breaking the working principle and design concept of traditional corrugated compensator. It has the advantages of simple structure, reasonable design, low cost and convenient installation.
