Description

Technical Field

[0001] The utility model belongs to the technical field of slip ring design, and in particular relates to a large-diameter multi-channel slip ring system suitable for gas, liquid and gas-powder mixed fluids. Background Art

[0002] Parts of the equipment usually need to rotate, but the pipes and cables are subject to rotational angle restrictions and cannot be bent or twisted. Otherwise, the service life of the equipment will be greatly reduced. In severe cases, gas, liquid, or mixed fluids may leak, causing unnecessary risks.

[0003] Many existing equipment mechanisms have pneumatic slip rings, electric slip rings, and hydraulic slip rings, but they all have size limitations. Their diameters are usually small due to structural limitations, which limits the flow rate of the fluid and reduces the feasibility of the local equipment structure.

[0004] In addition, the existing slip ring channels are relatively precise and can only realize single-channel or multi-channel with small diameter for ventilation or hydraulic pressure. There are few slip rings for fluids with powder or other mixed fluids, which can only be used for single channels and have diameter restrictions.

[0005] For multi-channels with powder mixed fluids, pure gas, etc., a large diameter is usually required. Existing slip rings are difficult to meet the needs, so a large-diameter multi-channel slip ring suitable for gas, liquid, and gas-powder mixed fluids is designed. Utility Model Content
