Abstract

The invention provides a central rotary joint, a pipe winder and continuous pipe operation equipment. The central rotary joint comprises a mandrel and a rotor. The mandrel comprises a sleeving part and a mounting part formed at one end of the sleeving part, one side of the mounting part is provided with a mounting surface, and a plurality of first liquid ports are formed in the mounting surface. Second liquid ports in one-to-one correspondence with the first liquid ports are formed in the rotor. A plurality of flow channels are formed on the mandrel, a plurality of ring cavities are formed between the sleeving part and the rotor, and each first liquid port communicates with the corresponding ring cavity through the corresponding flow channel. The flow channels comprise the first flow channel, the second flow channel and the third flow channel, and the distance between the axis of at least part of the third flow channel and the axis of the second flow channel communicating with the third flow channel is larger than zero. According to the central rotary joint, the distance between the axis of at least part of the third flow channel and the axis of the second flow channel communicating with the third flow channel is larger than zero, so that the structure of the central rotary joint is more compact, and the installation requirement of all pipelines on the first liquid ports can bemet.

Description

technical field [0001] The present application relates to the technical field of oil production engineering machinery, in particular to a rotary joint, a hose reel and coiled tubing operation equipment. Background technique [0002] In coiled tubing equipment, multiple pipelines are usually connected to a central rotary joint, and the central rotary joint usually includes a mandrel and a rotor that can rotate around the mandrel. The inlet and outlet of the pipeline are respectively connected with the mandrel and the rotor, wherein the pipeline at one end connected with the rotor is wound on the rotor and rotates together with the rotor. [0003] In the prior art, there are as many as 20 pipelines installed on the central rotary joint, thus forming 20 flow channels in the mandrel. In order to facilitate the disassembly of the connecting pipelines, a wrench for disassembling the pipelines needs to be reserved between the flow channels space, so the overall volume of the centr...
