AI Technical Summary
In a rotary fluid machine, the direction of movement when the fluid enters the impeller is opposite to the direction of rotation, resulting in energy loss and reduced efficiency.
A detachable fluid shunt guide is designed, using two intersecting guide curved surfaces and positioning devices (such as flanges or columns) to make the movement direction consistent with the impeller when the fluid enters the shell, reducing energy loss.
It improves energy conversion efficiency, reduces the resistance torque and shaft pressure of the impeller, and extends the service life.

Abstract
Description
Technical Field
[0001] The invention relates to a rotary fluid machinery, in particular to a detachable fluid flow distribution guide device. Background Art
[0002] In the machinery for converting the internal energy of fluid, the gear pump, Roots blower, twin-screw compressor and other machinery can do work through external force to increase the internal energy of the fluid, while the Roots expander, twin-screw expander and other machinery can do work through the fluid to reduce the internal energy of the fluid. This type of rotary fluid machinery includes a housing, a pair of end covers and a pair of impellers (or gears, screws), the housing is provided with an inlet and an outlet for the fluid, an 8-shaped cavity is provided inside the housing, and the two impellers are arranged in parallel in the cavity and mesh with each other. This type of rotary fluid machinery has a simple structure, low cost and durability. Its disadvantage is that after the fluid enters the separation side of the two impellers from the inlet, it directly hits the impeller. Since the movement direction of the fluid is opposite to the direction of rotation of the impeller, the rotational kinetic energy of the impeller is consumed, reducing the efficiency of energy conversion. Summary of the invention
[0003] The technical problem to be solved by the present invention is to provide a detachable fluid diverter guide, which can be installed on the above-mentioned rotary fluid machinery to change the direction of the fluid's directional movement, so that when the fluid entering the casing hits the impeller, its movement direction is consistent with the movement direction of the impeller edge, thereby reducing energy loss and improving the efficiency of energy conversion.
[0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: A detachable fluid flow diversion guide, wherein a flow diversion guide device and a positioning device are provided on the main body of the detachable fluid flow diversion guide.
[0005] The present invention can also be: the flow diversion guide device is two intersecting guide surfaces, and the flow diversion guide device can also be provided with two secondary guide surfaces. The positioning device can be a flange, the inner side of which is connected to the main body of the detachable fluid flow diversion guide; the positioning device can also be a column, the side of which is connected to the main body of the detachable fluid flow diversion guide. Of course, the positioning device can also be positioned using other existing technologies.
[0006] Compared with the prior art, the beneficial effects of the present invention are: (1) it can increase the dynamic torque of the impeller and reduce the resistance torque of the impeller, thereby improving the energy conversion efficiency; (2) it can reduce the shaft pressure and extend the service life.
