Abstract
The invention provides a bent pipeline structure for inhibiting flow distortion, which mainly comprises a bent pipe body and guide fins inside the pipe body, wherein the guide fins are arranged at the junction of a bent pipe according to the bent shape of the pipe and are used for guiding gas which is shunted or collected in the pipe. The flow guide rib can improve the flow of fluid at the junction of the elbow, avoid the mutual interference of the flow at the splitting/collecting part, and particularly obviously inhibit the flow distortion in the pipeline caused by the reversal of the impellers of the two gas compressors when the two splitting branch pipes are respectively connected with the inlets of the two supercharger gas compressors, thereby achieving the purpose of improving the efficiency of the system.
Description
Technical Field
The invention belongs to the technical field of exhaust gas turbocharging, and particularly relates to a bent pipeline structure for inhibiting flow distortion.
Background
The requirements for high power density and plateau power recovery of internal combustion engines require continuous improvement and optimization of the supercharging system performance so that the supercharging system can be well matched with the engine. The interior of the supercharging system and the connection of the supercharging system and the engine are usually connected by a bent pipeline.
In the traditional connecting bent pipe, because the fluid often generates flow mutual interference at the collection position of the branch pipes, the flow loss is increased, and the system efficiency is reduced. Therefore, the gas flow in the connecting pipeline needs to be controlled, and particularly, the three-way connecting pipe for connecting the inlets of the two supercharger compressors to the two branch pipes for the double-row supercharger and the two branch pipes arranged on a V-shaped and other non-straight engines respectively inhibits the flow distortion in the pipeline caused by the reversal of the impellers of the two compressors, effectively improves the gas flow in the pipeline and improves the system efficiency. Therefore, there is a need for a curved conduit structure that suppresses flow distortion so that the flow properties of a fluid therein are better.
Disclosure of Invention
In view of the above, the present invention is directed to a curved pipeline structure for suppressing flow distortion, so as to improve the flow of fluid at the junction of the curved pipe, avoid flow interference at the splitting/converging portion, significantly suppress flow distortion in the pipeline, and achieve the purpose of improving system efficiency.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
the utility model provides an restrain crooked type pipeline structure of flow distortion, includes crooked body, crooked body comprises a plurality of reposition of redundant personnel branch pipes and house steward handing-over, crooked body is inside to be arranged according to the water conservancy diversion fin that the crooked shape of pipeline arranged in return bend juncture.
Furthermore, 1 flow guide rib is arranged at the intersection of the two branch pipes, and 1-3 flow guide ribs are arranged at the intersection of each branch pipe according to the pipe diameter and the flow guide requirement.
Compared with the traditional bent pipeline, the bent pipeline structure for inhibiting flow distortion can control and improve the flow of fluid at a shunting/collecting part due to the flow guiding effect of the flow guiding fins, avoids flow mutual interference at the shunting/collecting part, and obviously inhibits the flow distortion in the pipeline caused by the reversal of the impellers of the two gas compressors particularly when the two shunting branch pipes are respectively connected with the inlets of the two supercharger gas compressors, thereby achieving the purpose of improving the efficiency of the system.
