Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of back adjustable backrest double sided impeller turbosupercharger, comprise: body 1, described body 1 offers at least 2 suction ports, be respectively and often drive gas port 2 into and can open and close suction port 3, described body 1 inside is provided with a pair of side pressure impeller 4, describedly often drive gas port 2 into and can open and close suction port 3 and be located at respectively the both sides that described bilateral is pressed impeller 4, described bilateral presses the output terminal of impeller 4 to be provided with diffusion passage 5, by described diffusion passage 5, be communicated with eddy current road 6, one sidewall of described diffusion passage 5 is provided with packaged type diffusion adjustment disk 7, described diffusion adjustment disk 7 is connected with a regulating valve.
Described switching on suction port 3 is equipped with and opens and closes valve 8, and described switching valve 8 is connected with a diffusion adjustment disk 7 by a linkage 9.By controlled opening/closing valve 8, can drive diffusion adjustment disk 7 to move by linkage 9.
By opening and closing the switching of suction port 3, increase or reduce the air inflow of gas compressor, in order to meet the motor requirement of large range of flow.
As shown in Figure 1, when switching valve 8 is closed condition, diffusion adjustment disk 7 is adjusted to minimum width by the channel width of diffusion passage 5.
When engine speed is lower, in the few situation of fuel injection quantity, the required air inflow of motor is few.Now open and close valve 8 and close and can open and close suction port 3, air can only enter by often driving gas port 2 into, presses under the effect of impeller 4 left side blades enter eddy current road 6 by diffusion passage 5 at bilateral.Now under the effect of linkage 9, diffusion adjustment disk 7 makes the width of diffusion passage 5 to meet current bilateral, press impeller 4 to only have the requirement in left side blade effect situation in minimum state.
As shown in Figure 2, when switching valve 8 is open mode, diffusion adjustment disk 7 is adjusted to Extreme breadth by the channel width of diffusion passage 5.
When engine speed high, fuel injection quantity is large, in the large situation of required air inflow, opening and closing valve 8 opens and can open and close suction port 3, make the air can be simultaneously from often driving gas port 2 into and can opening and closing suction port 3 air inlets, and bilateral presses the left and right sides blade of impeller 4 to play a role simultaneously, makes gas enter eddy current road 6 by diffusion passage 5.Now under the effect of linkage 9, diffusion adjustment disk 7 makes the width of diffusion passage 5 to meet current bilateral, press the requirement in impeller 4 left and right sides blades effect situation simultaneously in maximum rating.
At pressurized machine, under same rotating speed, the air inflow of two suction port air inlets is simultaneously the twices while only having a suction port air inlet, and the scope that whole gas compressor can offer the air inflow of motor has obtained quite effectively expansion.
Wherein, linkage 9 comprises connecting rod and push rod, connecting rod connecting valve valve and push rod, and described push rod is connected with diffusion adjustment disk 7, on described push rod, is equipped with spring structure.
Back adjustable backrest double sided impeller turbocharger arrangement of the present invention is simple, reliable, takes up room little, and large-scale air inflow can be provided, and meets the motor that air inlet area requirement is large, and effectively saves installing space.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
