Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, provide a kind of constant-voltage type Worm gear pressurizing unit scroll.As shown in Figure 3 and Figure 4, the present embodiment comprises volute body (as volute body 1), and is located at the inner and voltage stabilizing gas storage pack arrangement of gas flow orifice with described volute body inside of described volute body.
Particularly, above-mentioned voltage stabilizing gas storage pack arrangement, comprises the suction port be located at bottom volute body, and coordinates the gas storage bag (as gas storage bag 2) and the air outlet that are located at volute body inside; Suction port, gas storage bag, air outlet and gas flow interface, be communicated with successively.This gas storage bag is circle drum type, and described suction port and air outlet lay respectively at the two ends of round drum type gas storage bag; This suction port and air outlet are the circular hole that two sizes are not identical.The size of the size of gas storage bag and the circular hole at gas storage bag two ends, all can carry out accommodation according to the actual requirements.The intake interface (i.e. suction port) of gas storage bag, can adopt face-flange, and collar-type also can be adopted to connect
Placement between above-mentioned voltage stabilizing gas storage pack arrangement and volute body, can be adopt casting integrated integral type to connect (as shown in Figure 3), also can be adopt the spiral connection of split type assembling that is assembled of machining (as shown in Figure 4, by split type parts, be formed by connecting with screw flanged surface).
The constant-voltage type Worm gear pressurizing unit scroll of above-described embodiment, adopt voltage stabilizing gas storage pack arrangement, because this voltage stabilizing gas storage pack arrangement has the gas flow interface utilizing suction port, gas storage bag and air outlet and volute body inside, make the flow of waste gas in volute body inner flow passage drink pressure, can be stabilized in the default operating range of the pressurized machine matched with this constant-voltage type Worm gear pressurizing unit scroll; Meanwhile, the rotating speed of this pressurized machine work and performance characteristics also can be made can to mate (see Fig. 3) with single cylinder or twin cylinder engine.
The constant-voltage type Worm gear pressurizing unit scroll of above-described embodiment, there is air inlet, gas storage, give vent to anger after carry out the voltage stabilizing gas storage pack arrangement that does work again, gas flow, the pressure stability in volute body internal gas runner can be made, by selecting the pore size of air inlet, gas storage, gas storage, can meet and be matched in different engine characteristics, to guarantee that pressurized machine normally works, reliably.
Prove after tested, with the turbosupercharger of above-described embodiment constant-voltage type Worm gear pressurizing unit scroll, can as the normal startup on plateau of effective solution small power single cylinder machine, twin-tub machine and effective means and the method for recovering motor normal output.
The constant-voltage type Worm gear pressurizing unit scroll of above-described embodiment, in the middle of the suction port front end of volute body and the relief opening of motor, install voltage stabilizing gas storage pack arrangement (see Fig. 3) additional, motor combustion gas enters (can according to air inflow in voltage stabilizing gas storage pack arrangement suction port D hole, the diameter of Matching and modification suction port), unnecessary gas, by behind suction port D hole, in the gas storage bag entered, temporarily stores by waste gas; Gas storage bag mesopore regulates the use entering the useless pressure gas flow control of volute body internal gas runner, and the diameter in hole mainly meets pressurized machine and Engine Matching is as the criterion; By regulating gas storage bag (as Fig. 3) D hole and diameter of bore, select volume size more simultaneously, reach the engine calls that coupling is different.
As seen from Figure 1, Figure 2, the exhaust gas pressure of discharging to reach motor enters useless kinetic pressure in Worm gear pressurizing unit scroll will be stabilized in certain area, the pressure ratio coupling motor after pressurized machine acting, and reaches the effect of supercharging.Based on showing unstable exhaust gas conditions in Fig. 1, Fig. 2, the gas storage bag of volute body inside, mainly can reach 20ms(twin-tub), 30ms(single cylinder) stablize gas pressure in the time.
