Problems solved by technology

[0002] In actual working conditions, it is often necessary to pressurize two different media. Two independent centrifugal supercharging devices are commonly used to work independently, but they must be equipped with corresponding parts such as volutes. The structure is complex and bulky. Not available in some space-constrained environments

Embodiment 1

[0019] The present invention is a dual-channel supercharging device, such as figure 1 As shown, it includes the inner channel a and the outer channel b coaxially sleeved together, and the outlet ends of the inner channel a and the outer channel b are located at the same end of the axis, and the inlet ends are located at the other end of the axis, and the corresponding outlet It communicates with the inlet in the axial direction, and the inner channel a and the outer channel b are set as the air intake section and the booster section from front to back in turn. In the intake section and the booster section, the two fluids flow independently; A pressurization part is arranged in the pressurization section of the pressurization part, and the pressurization part pressurizes the fluid passing through the inner channel a and the outer channel b simultaneously. The pressurized part includes a centrifugal impeller 1 for sheathing on the rotor body c. The centrifugal impeller 1 is arra...

Embodiment 2

[0025] A two-channel pressurized device, such as figure 2 As shown, it includes the inner channel a and the outer channel b coaxially sleeved together, and the outlet ends of the inner channel a and the outer channel b are located at the same end of the axis; the inner channel a and the outer channel b are arranged sequentially from front to back Intake section and pressurized section, in the intake section and pressurized section, the two fluids flow independently; in their pressurized section, a pressurized part is arranged, and the pair of pressurized parts passes through the inner channel a and the outer channel b The fluid is pressurized at the same time.

[0026] The above-mentioned pressurized part includes a centrifugal impeller 1 for being sleeved on the rotor body c, and the centrifugal impeller 1 is arranged in the pressurized section of the inner passage, perpendicular to the direction of incoming flow; the outer end of the centrifugal impeller 1 is wound around ...

Abstract

The invention discloses a dual channel supercharging device. The dual channel supercharging device comprises an inner channel and an outer channel which are coaxially sleeved together. The outlet endof the inner channel and the outlet end of the outer channel are located at the same end of the axis. The inner channel and the outer channel are each sequentially provided with a gas inlet segment and a supercharging segment from front to back. In the gas inlet segment and the supercharging segment, two kinds of fluid flow independently. A supercharging part is arranged in the supercharging segment of each of the inner channel and the outer channel, and the supercharging parts supercharge the fluid of the inner channel and the outer channel at the same time. According to the dual channel supercharging device, two media are supercharged at the same time under the limited space condition.

Description

technical field [0001] The invention belongs to the technical field of gas, liquid and mixture pressurization, and in particular relates to a dual-channel pressurization device. Background technique [0002] In actual working conditions, it is often necessary to pressurize two different media. Two independent centrifugal supercharging devices are commonly used to work independently, but they must be equipped with corresponding parts such as volutes. The structure is complex and bulky. Not available in some space-constrained environments. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dual-channel pressurization device for simultaneously pressurizing two media under the condition of limited space, aiming at the shortcomings of the above-mentioned prior art. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is that a double-channel booster...
