Rotary system with flow holes on the rotating body

Abstract

The invention provides a rotating system with a through hole in a rotator, and belongs to the technical field of machinery design. The rotating system comprises a volumetric cavity, an elastic component, a rotator, a partition, a rotating shaft, a rotating plate and a chain, wherein the longitudinal section of the volumetric cavity is ring-shaped; the longitudinal section of a fixator and the longitudinal section of the rotator are arc-shaped; an exhaust pipe is a round pipe with the uniform section; both a first penetration pipe and a second penetration pipe are arranged in the fixator; and upper wall surfaces of the second penetration pipe are connected with each other through the elastic component and the partition. When the pressure of an air inlet pipe of an engine is high, the rotator drives the rotating plate to rotate anticlockwise, the necking rate of an exhaust manifold is high, and the pumping loss of the engine is low; and when the pressure of the air inlet pipe of the engine is low, the rotator drives the rotating plate to rotate clockwise, the necking rate of the exhaust manifold is low, the pulse energy can be sufficiently used, and the available energy of the front of a turbine is high. The rotating system is reasonable in design and simple in structure, and is applicable to a turbocharger system with a turbine inlet and a side turbine.

Description

Technical field [0001] The invention relates to a turbocharging system in the technical field of mechanical design, in particular to a rotating system with circulation holes on a rotating body. Background technique [0002] With the development of society and the improvement of environmental protection requirements, the application of engine supercharging technology has become more and more extensive. Most of the medium and high-power engines use turbocharging technology to increase power and reduce fuel consumption. The two basic types of turbocharging systems are constant pressure charging system and pulse charging system. Constant pressure supercharging system. Each cylinder shares a large exhaust pipe. The structure of the exhaust pipe system is relatively simple. The pressure in the exhaust pipe remains basically constant. The pressure is only related to the load and speed of the engine. The number of cylinders is different. The supercharging system of the diesel engine can...

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
