Abstract
The invention relates to a turbine volute structure meeting the requirement for containing a booster. The turbine volute structure comprises a turbine impeller (1), a turbine volute open gear (2), a double flow passage middle rib (3), turbine volute channels (4) and a turbine volute outer wall (5); the turbine impeller (1) is arranged on a turbine shaft (6); the reinforced double flow passage middle rib (3) is arranged in a turbine volute body provided with the turbine impeller (1); the double flow passage middle rib (3) separates the turbine volute body into two turbine volute channels (4); the turbine volute outer wall (5) of the turbine volute channel (4) on the right side is locally reinforced; the turbine volute open gear (2) is arranged in front of the double flow passage middle rib (3) at the inlets of the turbine volute channels (4). The outer wall of the turbine volute is reinforced and the turbine volute structure meets the requirement for containing scattered turbine blades.
Description
Technical field
The invention belongs to turbo-charger technical field, be specifically related to a kind of turbine box structure that pressurized machine contains that meets.
Background technique
Along with improving constantly of motor reinforcing degree, the reliability and safety of pressurized machine is had higher requirement.During pressurized machine overspeed, turbine wheel High Rotation Speed, under the effect of centrifugal force, turbine wheel may disperse, for the infringement that prevents its potential failure to cause, the containment that must improve turbine box, all wraps in turbine box the turbine fragment dispersing, and avoids the infringement of turbine fragment to other parts of motor and personnel thereof.The inclusive design of existing pressurized machine adopts turbine box to add anti-explosion cover mostly, and for middle-size and small-size motor, structure is compact, add anti-explosion cover after turbine box can not meet the requirement of motor to pressurized machine bulk.Pressurized machine has increased anti-explosion cover in addition, has also increased manufacture cost simultaneously.
Summary of the invention
Technical problem to be solved by this invention is exactly for limited space in pressurized machine, is the infringement that prevents turbine wheel may disperse and cause, and has proposed a kind of turbine box structure that pressurized machine contains that meets.
The technical solution used in the present invention: a kind of turbine box structure that meets pressurized machine containing, comprise turbine wheel 1, turbine box is opened shelves 2, rib 3 in the middle of double flow channel, turbine box passage 4, turbine box outer wall 5, turbine wheel 1 is installed on turbine shaft 6, in the turbine box casing of installing turbine wheel 1, be provided with the middle rib 3 of double flow channel of reinforcement, in the middle of double flow channel, rib 3 is divided into two turbine box passages 4 by turbine box casing, the wherein local reinforcement of turbine box outer wall 5 of the turbine box passage 4 on right side, described turbine box is opened shelves 2 and is arranged on before the middle rib 3 of double flow channel that enters turbine box passage 4 inlets.
The present invention compared with prior art its beneficial effect is:
The present invention adopts on the basis of conventional turbine box, strengthens the middle rib of turbine box double flow channel, and the local outer wall of strengthening turbine box, meets the containing to the turbine blade that disperses in addition.In this design space size, meet the requirement of motor to pressurized machine.Be the local outer wall of strengthening turbine box in addition, basic not increase in pressurized machine manufacture cost and weight.
By test of many times, show: when turbine wheel linear velocity 670m/s disperses, turbine box is intact.The containing rotating speed of turbine box promotes 1.2 times.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of turbine box structure that meets pressurized machine containing, comprise turbine wheel 1, turbine box is opened shelves 2, rib 3 in the middle of double flow channel, turbine box passage 4, turbine box outer wall 5, turbine wheel 1 is installed on turbine shaft 6, in the turbine box casing of installing turbine wheel 1, be provided with the middle rib 3 of double flow channel of reinforcement, in the middle of double flow channel, rib 3 is divided into two turbine box passages 4 by turbine box casing, the wherein local reinforcement of turbine box outer wall 5 of the turbine box passage 4 on right side, described turbine box is opened shelves 2 and is arranged on before the middle rib 3 of double flow channel that enters turbine box passage 4 inlets.
Claims (1)
1. one kind meets the turbine box structure that pressurized machine contains, comprise turbine wheel (1), turbine box is opened shelves (2), rib (3) in the middle of double flow channel, turbine box passage (4), turbine box outer wall (5), it is characterized in that: turbine wheel (1) is installed on turbine shaft (6), in the turbine box casing of installing turbine wheel (1), be provided with the middle rib (3) of double flow channel of reinforcement, in the middle of double flow channel, rib (3) is divided into two turbine box passages (4) by turbine box casing, wherein the turbine box outer wall (5) of the turbine box passage (4) on right side is local strengthens, described turbine box open shelves (2) be arranged on enter the double flow channel of turbine box passage (4) inlet in the middle of rib (3) above.
