Description
Technical field
The utility model relates to motor auxiliary spare part technical field, particularly relates to a kind of anti-surge control device for engine supercharger.The utility model also relates to a kind of pressurized machine comprising above-mentioned anti-surge control device.
Background technique
For realizing Engine Downsizing, high power, low oil consumption design, supercharging technology application is on the engine more and more general, due to the complexity of car load operating mode, pressurized machine need do adaptability design to different operating mode, when car load anxious accelerator releasing, now closed throttle under middle and high load working condition work, a large amount of pressurized gas will be gathered in pipeline before closure and after blower outlet, as discharged by gas not in time, high pressure air knows from experience reverse impact compressor impeller, affects the pressurized machine life-span; This operating mode easily makes pressurized machine produce surge noise simultaneously, for anti-situation of planting here occurs, pressurized machine is all designed with recycle valve, pressurized gas earial drainage after pressurized machine recycle valve can make supercharging under specific operation, before supercharging, makes the gas before the gas after supercharging and supercharging realize Inner eycle in pressurized machine inside.
Please refer to Fig. 1-Fig. 4; Fig. 1 is the structural representation of a kind of typical pressurized machine in prior art; Fig. 2 is the schematic diagram of the other direction of pressurized machine shown in Fig. 1; Fig. 3 is the partial sectional view at recycle valve place in pressurized machine shown in Fig. 1; The connection diagram that Fig. 4 is recycle valve shown in Fig. 3 and intake manifold.
As shown in the figure, the recycle valve 3 of this pressurized machine is integrated in compressor housings, recycle valve 3 forms primarily of preloading spring 301, elastomer diaphragm 302, normally off is in for making recycle valve, spring is in compressive state and acts on elastomer diaphragm with the pretightening force producing suitable size, outlet 201 places after elastomer diaphragm is pressed in, under preventing normal working, the pressure release of blower outlet 2 pressurized gas is to compressor inlet 1, makes pressurized machine lose the effect of supercharging.Recycle valve 3 is communicated by connecting hose 4 with intake manifold 5, so intake manifold intracavity gas communicates with gas in recycle valve elastomer diaphragm 302, can ensure that the pressure in two cavitys is substantially identical like this, motor is when middle and high load working condition works, it is substantially identical that intake manifold 5 cavity pressure and pressure export 201 place's pressure afterwards, recycle valve elastomer diaphragm is at intake manifold 5 pressure, outlet 201 pressure after pressure, entrance 202 pressure before pressure, closed condition is under the effect of initial tension of spring, after supercharging, pressurized gas all enter in intake manifold, and then enter combustion chambers burn.
When car load works at middle and high load working condition, now anxious accelerator releasing, closed throttle in intake manifold, after supercharging, pressurized gas cannot enter intake manifold again, now supercharger rotor impeller proceeds supercharging under effect of inertia, a large amount of pressurized gas are gathered instantaneously in pipeline before closure and after supercharging, due to closed throttle, intake manifold intracavity gas is in larger negative pressure state, because recycle valve communicates with intake manifold, so also there is larger negative pressure in recycled rubber diaphragm 302, now elastomer diaphragm overcomes initial tension of spring Compress Spring under suction function, diaphragm moves upward, recirculation (egr) valve is opened, after pressure, outlet 201 place's pressurized gas can by entrance 202 place before valve pressure release to pressure, such blower outlet 2 pressurized gas and compressor inlet 1 gas form Inner eycle in pressurized machine inside.
But, when using above-mentioned pressurized machine, car load is under middle high loaded process state, anxious accelerator releasing, closed throttle, air-distributor pressure enters negative pressure state by high pressure needs the regular hour, intake manifold negative pressure is delivered to recycle valve diaphragm chamber by flexible pipe simultaneously also needs the regular hour, recycle valve is caused to be opened slower, responsiveness is poor, in anxious accelerator releasing process, can not in time by before pressurized gas pressure release to supercharging, pressurized machine is easily caused to produce surge noise, the pressurized gas simultaneously gathered in a large number easily produce disappointing noise by pressure relief valve instantaneously, affect the travelling comfort of car load, further, above-mentioned recycle valve opening time only can be determined by intake manifold negative pressure building-up time, and recycle valve controls underaction, and the response time is longer and uncontrollable.
Therefore, a kind of anti-surge control device for pressurized machine is provided, make its recirculation control valve opening time not by the restriction of intake manifold negative pressure building-up time, improve the opening and closing controllability of recirculation control valve, thus ensure that pressurized machine bleeding process is reliable in time, avoid pressurized gas to assemble the disappointing noise caused, prevent motor generation surge, improving car load travelling comfort, needing the problem of solution with regard to becoming those skilled in the art badly.
