Description
Technical field
The utility model relates to the anti-surge installation of a kind of supercharger, specifically supercharger.
Background technology
Supercharger is widely used in diesel engine arts, has reached inorganic unpressurized degree, it may be said that supercharging
Device has had become as the parts that diesel engine is indispensable.But the supercharging to be far longer than of the working range of diesel engine
Device, it is extremely difficult with mating of diesel engine that this results in supercharger.Generally, generally by supercharger
Fitting between the high load region of diesel engine, this results in diesel engine when underload, and supercharger flow is too small.And
Turbocharger surge can be caused when supercharger flow is too small, seriously may result in supercharger damage.
Therefore, it is to avoid the surge of supercharger becomes emphasis and the difficult point of supercharger diesel engine coupling.People are also
Proposing a lot of effective method, such as casing bleed, high operating mode is exitted, and two-step supercharging increases in succession
The means such as pressure.But these methods, some meetings seriously reduce the work efficiency of supercharger, and will not be along with bavin
The duty of oil machine and supercharger is automatically adjusted, and some is the most complicated, changes supercharger and pressure charging system
Make excessively complicated.
Summary of the invention
The purpose of this utility model be to provide can solve the problem that surge problems that supercharger occurs when underload from
And expand the diffuser bypass anti-surge installation of supercharger range of flow.
The purpose of this utility model is achieved in that
This utility model diffuser bypass anti-surge installation, is characterized in that: include diffuser shell, diffuser
Blade, electromagnetic valve, diffuser shell is installed with diffuser vane, and baffle plate retaining wall is fixed on diffuser
On shell, electromagnetic valve is arranged on baffle plate retaining wall, and the electromagnetism valve stem end of electromagnetic valve is installed moving up and down
Baffle plate, the stroke of baffle plate is respectively positioned in baffle plate retaining wall, when electromagnetism valve rod is positioned at lowermost end, baffle plate and diffuser
Blade is fitted, and after electromagnetism valve rod promotes, pressure face and the suction surface of diffuser vane communicate.
Advantage of the present utility model is: this utility model can solve the problem that what supercharger occurred when underload breathes heavily
Shake problem, thus expand supercharger range of flow.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model；
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Illustrate below in conjunction with the accompanying drawings and this utility model be described in more detail:
In conjunction with Fig. 1～2, diffuser shell 6 is fixed together with diffuser vane 1, when baffle plate 7 with
When diffuser vane 1 is fitted, the runner that gas can only be formed between two blades flows.Baffle plate retaining wall
5 are fixed on diffuser shell 6, are placed with baffle plate 7 between baffle plate retaining wall, and baffle plate 7 can be up and down,
Baffle plate 7 is fixed together with electromagnetism valve rod 3, the control by electromagnetic valve 2 of moving of electromagnetism valve rod 3, and electric
The electric current that magnet valve 2 is then transmitted through solenoid valve control circuit by diesel engine control system controls.
Control process of the present utility model is as follows: the rotating speed of diesel engine control system monitoring supercharger and pressure
Power, flow, when finding that supercharger approaches stall margin, calculate what baffle plate promoted according to flow and tachometer
Highly, thus obtaining bestowing the size of current of electromagnetic valve, then electric current is transmitted by solenoid valve control circuit 4
To electromagnetic valve 2, electromagnetic valve 2 promotes electromagnetism valve rod 3 and baffle plate 7 arrives certain altitude, in the both sides shape of blade
Becoming passage, the gas of pressure face and suction surface just can mutually circulate, and decreases wall and separates, thus contains
The surge of supercharger, expands the range of flow of supercharging.
Fig. 1 is that diffuser bypasses anti-surge installation schematic top plan view, it can be seen that when baffle plate is close to diffuser
During vane tip, fluid can only flow from the runner that two blades are formed, and after baffle plate promotes, fluid can
Mutually flow with the both sides at a blade.
The rotating speed of diesel engine control system monitoring supercharger and pressure, flow, when finding that supercharger approaches surge
During border, calculate, according to flow and tachometer, the height that baffle plate promotes, if the least, shadow to surge
Ring the least, if the most excessive, then substantial amounts of fluid can be made to flow out from passage, so that diffusion ability
Declining, outlet pressure declines, so that the efficiency of supercharger declines, thus obtains bestowing the electricity of electromagnetic valve
Stream size, then electric current is transferred to electromagnetic valve 2 by solenoid valve control circuit 4, the electricity that electromagnetic valve 2 produces
Magnetic force promotes electromagnetism valve rod 3 and baffle plate 7 to certain altitude, forms passage in the both sides of blade, pressure face and
The gas of suction surface just can mutually circulate, and decreases wall and separates, thus contained the surge of supercharger, expands
The big range of flow of supercharging.When supercharger operating point is away from stall margin, diesel engine control system disconnects
Power supply to electromagnetic valve 2, baffle plate 7 falls back to above diffuser vane, cut off pressure face and suction surface it
Between the flowing of fluid, thus ensure that, at big range of flow internal supercharger, there is higher operational efficiency.
