Abstract
The utility model discloses a detachable fluid diversion guide, which aims to provide a diversion guide device which is used for a specific rotary fluid machine and can change the movement direction of fluid so as to improve the efficiency. The detachable fluid diversion guide comprises a diversion guide device and a positioning device which are arranged on a main body of the detachable fluid diversion guide. The utility model can be used for machines such as gear pumps, roots fans, double-screw compressors and the like, and can also be used for machines such as Roots expanders, double-screw expanders and the like.
Description
Technical Field
The present utility model relates to rotary fluid machines, and more particularly to a removable fluid diversion guide.
Background
In the machines for converting the internal energy of the fluid, the gear pump, the Roots blower, the double-screw compressor and other machines can do work through external force to increase the internal energy of the fluid, while the Roots expander, the double-screw expander and other machines can do work through the fluid to the outside to reduce the internal energy of the fluid. Such rotary fluid machines comprise a casing provided with a fluid inlet and a fluid outlet, a pair of end caps and a pair of impellers (or gears, screws) arranged in parallel in said cavities and engaged with each other, and an 8-shaped cavity inside said casing. The rotary fluid machinery has simple structure, low cost and durability. The defects are that: after entering the separation sides of the two impellers from the inlet, the fluid directly impacts the impellers, and the rotational kinetic energy of the impellers is consumed due to the fact that the movement direction of the fluid is opposite to the rotation direction of the impellers, so that the energy conversion efficiency is reduced.
Disclosure of Invention
The utility model aims to provide a detachable fluid diversion guide, which is arranged on the rotary fluid machine, and can change the direction of directional movement of fluid, so that when the fluid entering a shell impacts an impeller, the movement direction of the fluid is ensured to be consistent with the movement direction of the edge of the impeller, thereby reducing energy loss and improving the efficiency of energy conversion.
In order to solve the technical problems, the utility model adopts the following technical scheme: a detachable fluid diversion guide is provided with a diversion guide device and a positioning device on the main body.
The utility model can also: the split-flow guiding device is provided with two intersecting guiding curved surfaces, and the split-flow guiding device can be further provided with two secondary guiding curved surfaces. The positioning device can be a flange, and the inner side of the flange is connected with the main body of the detachable fluid diversion guide; the positioning means may also be a column with sides connected to the body of the removable fluid diversion guide. Of course, the positioning device can also adopt other prior art to perform positioning.
Compared with the prior art, the utility model has the beneficial effects that: the method has the advantages that the power moment of the impeller can be increased, the resistance moment of the impeller is reduced, and therefore the energy conversion efficiency is improved; and the shaft pressure is reduced, and the service life is prolonged.

Detailed Description
Case one:
in fig. 1 and 2, a main body of a detachable fluid diversion guide with a flange is provided with two guiding curved surfaces 1 and two secondary guiding curved surfaces 2, and the two guiding curved surfaces 1 intersect to form a diversion blade 3. The main body of the detachable fluid diversion guide with the flange plate is also provided with the flange plate 4, and the inner side of the flange plate 4 is connected with the main body of the detachable fluid diversion guide with the flange plate. In fig. 4 and 5, an expander housing 8 is provided with a flange which is adapted to the flange 4. As shown in fig. 8 and 9, a removable fluid diversion guide with flanges is coupled to the expander by corresponding flange positioning so that the direction of fluid movement into the expander is in line with the direction of rotation of the impeller.
Case two:
in fig. 3, a body of a detachable fluid diversion guide with a column is provided with two guiding curved surfaces 1 and two secondary guiding curved surfaces 2, and the two guiding curved surfaces 1 intersect to form a diversion blade 3. The two sides of the main body of the detachable fluid diversion guide with the column are provided with the column 5, and the column 5 is used for positioning. As shown in fig. 6 and 7, a groove 9 matched with the column 5 is arranged at the inlet of the gear pump shell. As shown in fig. 10, a removable fluid split guide 6 with a post is positioned in connection with a gear pump housing 7.
The utility model and its embodiments have been described above without limitation, and the actual construction is not limited thereto. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution can be designed without departing from the inventive concept and without the inventive concept, and the utility model shall fall within the protection scope of the present utility model.
