Abstract
The utility model belongs to the technical field of turbochargers, and relates to a double-flow-channel turbocharger volute. The double-flow-channel turbocharger volute comprises a volute body. A partition wall divides a flow channel of the volute body into a left side flow channel and a right side flow channel. The double-flow-channel turbocharger volute is characterized in that grooves are formed in the partition wall in an extending mode, the number of the grooves is two, and the two grooves are symmetrically formed in the two end faces of the partition wall. The double-flow-channel turbocharger volute is simple, compact and reasonable in structure, capable of effectively improving the reliability of the turbocharger volute, simple in manufacturing, and capable of saving part of material cost.
Description
Technical field
The utility model belongs to turbo-charger technical field, relates to a kind of Double flow path turbo-charger spiral case.
Background technique
During turbocharger operation, turbine shroud is constantly heated and is cooling.When motor starts from the state of cooling, the temperature of turbine shroud is substantially with extraneous the same, but its temperature can sharply rise in normal course of operation, thereby causes volute to expand.After motor is switched off, volute just begins to cool down and shrinks.The reexpansion of volute and cooling contraction make it easily produce thermal fatigue cracking, are especially expanding and the different place of shrinkage possibility.Spiral case inlet flange is one of place needing most concern, easily at the fillet place of flange, produces very high thermal stress.
But existing double flow channel spiral case also has inevitable defect, be mainly spiral case in use, because temperature cycles easily causes spiral case flange, crack, and produce thermal fatigue failure, have a strong impact on the global reliability of pressurized machine.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Double flow path turbo-charger spiral case simple in structure, ingenious, rational is provided, and this spiral case manufacturing is simple, and spiral case global reliability is high.
The technological scheme providing according to the utility model: a kind of Double flow path turbo-charger spiral case, comprise spiral case, division wall is divided into left side runner and right side runner by the runner of described spiral case, is characterised in that: on described division wall, extend and be provided with groove.
As further improvement of the utility model, described groove has two, and two grooves are symmetricly set on the end face of division wall both sides.
As further improvement of the utility model, described groove has one, and this groove is arranged on the either side end face of division wall.
As further improvement of the utility model, described groove connects division wall both ends of the surface, links up left side runner and right side runner.
As further improvement of the utility model, described groove extends to spiral case aditus laryngis portion.
As further improvement of the utility model, described groove extends to division wall end.
As further improvement of the utility model, described groove longitudinal section semicircular in shape.
Compared with prior art, advantage is the utility model: the utility model is simple in structure, compact and reasonable, can effectively improve the reliability of spiral casing of pressure booster, and spiral case manufacturing is simple, can save part cost of material.

Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Fig. 1 ~ 5, comprise spiral case 1, groove 2, flange 3, division wall 4, left side runner 5, right side runner 6 etc.
As shown in Figure 1, the first mode of execution of the present utility model: a kind of Double flow path turbo-charger spiral case, comprise spiral case 1, division wall 4 is divided into left side runner 5 and right side runner 6 by the runner of described spiral case 1, division wall 4 is positioned on the both sides end face of runner and extends a groove 2 is set respectively, and two groove 2 is symmetricly set in division wall 4 both ends of the surface, concentrated for effectively eliminating stress, groove 2 longitudinal sections arrange semicircular in shape, in concrete practice, as shown in Figure 5, the groove 2 for the full division wall turbosupercharger of double flow channel spiral case extends to spiral case aditus laryngis place; As shown in Figure 4, for the groove 2 of double flow channel part division wall turbosupercharger spiral case, extend to division wall 4 rear end, and for guarantee spiral case whole stressed evenly, groove 2 is opened in division wall 4 intermediate portions conventionally.
Fig. 2 shows the second mode of execution of the present utility model, the difference of this mode of execution and the first mode of execution is, on division wall 4, only offer a groove 2, groove 2 can be opened in and also can be opened in right side runner 6 in division wall 4 upper left side runners 5, be that assurance flange 3, division wall 4 are stressed evenly, groove 2 is preferably opened in the intermediate portion of division wall 4 simultaneously.
Fig. 3 shows the third mode of execution of the present utility model, the difference of this mode of execution and above-mentioned two kinds of mode of executions: groove 2 is a through slot, that is, groove 2 is opened in the place, neutral position of division wall 4, and groove 2 is linked up left side runner 5 and right side runner 6.
More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
The utility model is simple in structure, compact and reasonable, can effectively improve the reliability of spiral casing of pressure booster, and spiral case manufacturing is simple, can save part cost of material.
