Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
According to the utility model embodiment, 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 (such as volute body 1), and the voltage stabilizing gas storage pack arrangement that is located at described volute body interior and is communicated with the gas flow interface of described volute body interior.
Particularly, above-mentioned voltage stabilizing gas storage pack arrangement comprises the suction port that is located at volute body bottom, and cooperates gas storage bag (such as gas storage bag 2) and the air outlet that is located at the volute body interior; Suction port, gas storage bag, air outlet and gas flow interface are communicated with successively.This gas storage bag is the 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 two circular holes that size is not identical.The size of the circular hole at the size of gas storage bag and gas storage bag two ends all can be carried out accommodation according to the actual requirements.The intake interface of gas storage bag (being suction port) can adopt face-flange, also can adopt collar-type to connect
Placement between above-mentioned voltage stabilizing gas storage pack arrangement and the volute body, can be to adopt the casting integrated integral type that forms to connect (as shown in Figure 3), also can be to adopt the spiral connection of split type assembling that the machining assembling forms (as shown in Figure 4, with split type parts, be formed by connecting with the 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 that utilizes suction port, gas storage bag and air outlet and volute body interior, make the flow of waste gas in the volute body interior runner drink pressure, can be stabilized in the default operating range of the pressurized machine that is complementary with this constant-voltage type Worm gear pressurizing unit scroll; Simultaneously, also can make the rotating speed of this pressurized machine work and performance characteristics and single cylinder or twin cylinder engine can mate (referring to Fig. 3).
The constant-voltage type Worm gear pressurizing unit scroll of above-described embodiment, the voltage stabilizing gas storage pack arrangement that has air inlet, gas storage, does work again after giving vent to anger, can make gas flow, pressure stability in the volute body interior gas flow, by selecting the pore size of air inlet, gas storage, gas storage, can satisfy being matched in different engine characteristicses, to guarantee pressurized machine normal operation, reliable.
Proof with the turbosupercharger of above-described embodiment constant-voltage type Worm gear pressurizing unit scroll, can be used as the normal startup on the plateau of effective solution small power single cylinder machine, twin-tub machine and effective means and the method for recovery motor normal output after tested.
The constant-voltage type Worm gear pressurizing unit scroll of above-described embodiment, in the middle of the relief opening of the suction port front end of volute body and motor, installed voltage stabilizing gas storage pack arrangement (referring to Fig. 3) additional, the motor combustion gas enters (can be according to air inflow in the voltage stabilizing gas storage pack arrangement suction port D hole, the diameter of Matching and modification suction port), waste gas is by behind the suction port D hole, in the gas storage bag that has entered, unnecessary gas temporarily stored; Gas storage bag mesopore is the usefulness of regulating the waste gas body flow pressure control that enters volute body interior gas flow, and the diameter in hole mainly satisfies pressurized machine and Engine Matching is as the criterion; By regulating gas storage bag (such as Fig. 3) D hole and diameter of bore, selecting again volume size simultaneously, reach the different motor requirement of coupling.
As seen from Figure 1, Figure 2, useless kinetic pressure will be stabilized in certain area in the Worm gear pressurizing unit scroll for the exhaust gas pressure that reaches the motor discharge enters, and the pressure ratio after the pressurized machine acting is mated motor, and reaches the effect of supercharging.Based on showing unstable exhaust situation among Fig. 1, Fig. 2, the gas storage bag of volute body interior mainly can reach the 20ms(twin-tub), the 30ms(single cylinder) stablize gas pressure in the time.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
