Description
Technical field
The present invention relates to a kind of turbocharger test device, relate to a kind of variable cross section supercharger gear train reliability test bench that is used to test specifically.
Background technology
The gear train of variable cross section supercharger is constantly regulated nozzle vane according to the actual condition of engine, to realize and engine better matching under different operating modes.But the nozzle vane axle of the gear train that generally uses now and nozzle vane will have bigger gap to realize the rotation of nozzle vane.Because when the existence in gap can make turbocharger operation; There are bigger noise and vibration; And high temperature and high speed waste gas also has very gear train through the gap and seriously influences; These all can influence the reliability and the life-span of gear train, so the reliability quality of variable cross section supercharger gear train has very big influence to the performance and life-span of variable cross section supercharger.But the present domestic testing equipment that does not also have to test specially variable cross section supercharger gear train reliability; Therefore; Design a kind of novel changable cross section supercharger gear train reliability test and be necessary, this improvement for the exploitation of instructing variable cross section supercharger new product and structure is significant.
Summary of the invention
The problem that the present invention will solve is the test unit that has no test variable cross section supercharger gear train reliability to domestic; A kind of variable cross section supercharger gear train reliability test bench is provided, can analyzes, test variable cross section supercharger reliability through test.
In order to address the above problem, the present invention adopts following technical scheme:
A kind of variable cross section supercharger gear train reliability test bench; Comprise the empty filter that connects through pipeline successively, big air tank, solenoid valve, little air tank; Said little air tank is connected with gear train, and solenoid valve is connected with controller, and closing by controller of said solenoid valve controlled.
Below be the further improvement of the present invention to such scheme:
On the connecting tube between said empty filter and the big air tank restricting element and pressure maintaining valve are installed.
Further improve:
On the pipeline that between little air tank and gear train, is communicated with restricting element is installed.
The present invention adopts such scheme, and when solenoid valve was opened, pressurized air entered into little air tank, and air promotes flexible sheet through the elastic force that overcomes back-moving spring behind the restricting element and drives the motion of supercharger gear train then.After the solenoid valve release, the gaseous tension that gets into little air tank reduces, because the existence of back-moving spring pretightning force can realize the to-and-fro movement of supercharger gear train.
The another kind of improvement:
The first high-speed switch valve is installed on the pipeline between said solenoid valve and the little air tank, the second high-speed switch valve is installed on the release pipeline of little air tank.
The first high-speed switch valve is the pressure of adjustments of gas rapidly.
The second high-speed switch valve can change gaseous tension at short notice rapidly, improves the response of supercharger gear train.
Adopt such scheme; Compressed air source is introduced into big air tank behind restricting element and pressure maintaining valve, flow into solenoid valve again, and the switching of solenoid valve is controlled by controller; Get into little air tank through first acceleration switching valve gas behind the door; Gas promotes flexible sheet and drives the motion of supercharger gear train through overcoming in the cylindrical shell elastic force near the back-moving spring on flexible sheet right side behind the restricting element then, to the rapid release of little air tank, the interior gaseous tension of little air tank is reduced through the second quick Open valve rapidly; Because the existence of back-moving spring pretightning force can realize the to-and-fro movement of supercharger gear train.
The another kind of improvement:
Two parallelly connected high-speed switch valves are installed on the pipeline between said solenoid valve and the little air tank, one of them with cylindrical shell in be communicated with near the cavity in the left side of piston, another cavity with the interior right side near piston of cylindrical shell is communicated with.
Further improve:
The high-speed switch valve of two parallel connections is the 3rd high-speed switch valve, the 4th high-speed switch valve; Said the 3rd high-speed switch valve is in series with the 6th high-speed switch valve; The 4th high-speed switch valve is in series with the 5th high-speed switch valve, and said the 6th high-speed switch valve is communicated with the 5th high-speed switch valve.
The pressure reduction of the open and close controlling piston both sides through four high-speed switch valves; Lean on the motion of the gas differential pressure realization gear train of piston both sides; Make the gaseous tension control of both sides freer; The employing acceleration switching valve can change the pressure of gas behind the door at short notice rapidly, improves the response of supercharger gear train.
In the testing table course of work; When the 3rd high-speed switch valve is opened, the 4th high-speed switch valve is closed; The 5th high-speed switch valve is closed, when the 6th high-speed switch valve is opened, piston right side gaseous tension reduces rapidly, pressurized air gets into the piston left side; Cylindrical shell inner carrier left side gaseous tension promotes piston toward right motion greater than the right side gaseous tension.
When the 3rd high-speed switch valve is closed, the 4th high-speed switch valve is opened; The 5th high-speed switch valve opens, when the 6th high-speed switch valve is closed; Piston left side gaseous tension reduces rapidly; Pressurized air gets into the piston right side, and cylindrical shell inner carrier right side gaseous tension promotes piston toward right motion greater than the left side gaseous tension.
The pressure reduction of the open and close controlling piston both sides through four high-speed switch valves is realized the to-and-fro movement of supercharger gear train.
