Description
Technical field
The utility model relates to worm gear machine technical field, particularly relates to a kind of adjustable turbo machine that is applicable to turbosupercharger.
Background technique
Turbosupercharger is actually a kind of air compressor, increases air inflow by pressurized air.It is that the waste gas inertia impulsive force that utilizes motor to discharge promotes the turbine in turbine chamber, and turbine drives again coaxial impeller, and the air that impeller force feed is sent here by air-strainer pipeline makes it supercharging and enters cylinder.When engine speed speeds, the waste gas velocity of discharge is also synchronizeed and is speeded with secondary speed, and impeller just compresses more air and enters cylinder, and the pressure of air and density increase the more fuel that can burn, corresponding increase fuel quantity and adjust the rotating speed of motor, just can increase the output power of motor.
Turbosupercharger is widely used in the machinery such as vehicular engine, marine engine, power generating equipment and engineering machinery.It can significantly improve engine performance, energy-saving and emission-reduction.Along with the increasingly stringent of motor emission regulation demands, the performance of turbosupercharger is also had higher requirement.In the turbosupercharger in conventional variable cross section, its adjustable vane is molar behavior, and in changing air inlet area, variation has occurred the angle of whole blade, makes its angle inconsistent with the angle of the waste gas motion entering, the incident loss that has increased waste gas.

In preferred embodiment of the utility model, described fixed guide vane is fixed on diversion disk, on the inner of described fixed guide vane, there is an arc groove, on described adjustable guide vane, there is arc end, described arc end matches with arc groove, has the rotatingshaft that runs through described diversion disk on described arc end.
In preferred embodiment of the utility model, described adjustable guide vane entirety is wedge shape.
In preferred embodiment of the utility model, described adjustable guide vane entirety is wing.
In preferred embodiment of the utility model, described turbo machine also comprises final controlling element, link assembly and volute, described volute inside is provided with synchronous circle, on described synchronous circle, rocking arm is installed, the other end of described rocking arm is connected with described rotatingshaft, described synchronous circle is also connected with master rocker by connecting pin, and described link assembly is connected with final controlling element and master rocker respectively.
The beneficial effects of the utility model are: the adjustable turbo machine of the utility model, simple in structure, reliable, by the cooperation of fixed guide vane and adjustable guide vane, the incident loss of waste gas is dropped in making air inlet area at waste gas adjustable minimumly, improve turbine efficiency.
