Double through pipe type rotation mechanism

Abstract

A double through pipe type rotation mechanism in the technical field of mechanical design comprises a capacity cavity, an elastic component, a rotating body, a partition plate, a rotating shaft, a rotating plate and a chain. The vertical section of the capacity cavity is ring-shaped, the vertical section of a fixed body and the vertical section of the rotating body are arc-shaped, exhaust pipes are uniform-section round pipes, a first through pipe and a second through pipe are arranged in the fixed body, and the upper wall surface of the second through pipe is connected with the partition plate through the elastic component. When pressure of an engine intake pipe is high, the rotating body drives the rotating plate to rotate counterclockwise, throat opening areas of the exhaust pipes are large, and engine pumping loss is small; when pressure of the engine intake pipe is small, the rotating body drives the rotating plate to rotate clockwise, throat opening areas of the exhaust pipes are small, pulse energy can be fully utilized, and turbine front available energy is much. The double through pipe type rotation mechanism is reasonable in design, simple in structure and suitable for a turbocharging system with one turbine inlet and a turbine arranged on the side.

Description

technical field [0001] The invention relates to a turbocharging system in the technical field of mechanical design, in particular to a double-through-pipe rotating mechanism. Background technique [0002] With the development of society and the improvement of environmental protection requirements, the application of engine supercharging technology is becoming more and more extensive. Most of the engines with medium and high power adopt turbocharging technology to improve power and reduce fuel consumption. The two basic types of turbocharging systems are constant pressure supercharging system and pulse supercharging system. Constant pressure supercharging system, each cylinder shares an exhaust pipe with a large volume, the structure of the exhaust pipe system is relatively simple, the pressure in the exhaust pipe is basically kept constant, the pressure is only related to the load and speed of the engine, different cylinder numbers The supercharging system of the diesel eng...

AI Technical Summary

Problems solved by technology

[0003] After searching the existing technical literature, it is found that Chinese patent number ZL201020532937.0, patent name: turbocharger device with variable exhaust pipe outlet area, this patent technology provides a device with continuously variable exhaust pipe outlet area , can better take into account the high and low speed conditions of the engine; but the change of the outlet area of ​​the exhaust pipe is realized by the rotation of the rotary handle, which requires adding a special control mechanism to control the rotation of the rotary handle, so that Make the supercharging system structure more complicated
