Abstract

The invention discloses a rotary flow guiding device and aims to provide the rotary flow guiding device enabling liquid to be led in and led out during rotation. The rotary flow guiding device comprises a shaft sleeve and a hollow shaft, wherein the hollow shaft is rotationally connected with the shaft sleeve through a bearing; a water inlet hole and a water outlet hole in the shaft sleeve are communicated with an annular water inlet groove and an annular water outlet groove formed in the hollow shaft respectively; the annular water inlet groove and the annular water outlet groove are respectively communicated with a water inlet hole and a water outlet hole formed in the hollow shaft; sealing rings are arranged on the upper and lower surfaces of the annular water inlet groove and the annular water outlet groove respectively; a water inlet connecting pipe is connected with the water inlet hole in the hollow shaft, and a water outlet connecting pipe is connected with the water outlet hole in the hollow shaft; the bearing is arranged on the right side of the corresponding sealing ring on the right side of the annular water outlet groove and is used for rotationally connecting the shaft sleeve and the hollow shaft. The rotary flow guiding device is applicable to flow guidance of the liquid capable of flowing, such as water and oil, and can also be used for flow guidance of gas.

Description

technical field

[0001] The invention relates to a rotary flow guide device, which is mainly used for flow guide of flowing liquid. Background technique

[0002] In production and application, the flowing liquid is fixedly connected to the working device of the required liquid through the conduit. When the liquid completes its mission, it is directly discharged from the working device; The flowing liquid is introduced into a relatively rotating working device, and when the liquid needs to be discharged from the relatively rotating working device after the liquid completes its mission, this specific operation requirement cannot be met. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a rotary flow guiding device capable of introducing and exporting liquid during rotation.

[0004] The present invention is accomplished in this way. A rotary flow guide device includes a shaft sleeve and a hollow shaft. The hollow sha...

Embodiment Construction

[0009] The present invention is further described in detail in conjunction with the accompanying drawings. A rotary flow guide device includes a shaft sleeve 7 and a hollow shaft 11. The hollow shaft 11 is rotationally connected with the shaft sleeve 7 through a bearing 6. The water inlet provided on the shaft sleeve 7 The hole 1 and the water outlet hole 10 communicate with the water inlet annular groove 8 and the water outlet annular groove 4 respectively on the hollow shaft 11, and the upper and lower sides of the water inlet annular groove 8 and the water outlet annular groove 4 are provided with sealing rings 9. The water inlet annular groove 8 and the water outlet annular groove 4 communicate with the water inlet connecting pipe 12 and the water outlet connecting pipe 13 respectively arranged in the hollow shaft 11 .

[0010] In order to ensure that the hollow shaft 11 can run normally, an oil filling hole 2 is provided on the bearing sleeve.
