Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
Referring to fig. 2-5, an embodiment of the present invention discloses a novel silencing cover, which includes a first cover body 10 and a second cover body 20, wherein the first cover body 10 is covered above the second cover body 20; the first cover body 10 is provided with an air outlet 11, the second cover body 20 is provided with an air outlet 21, and the air outlet 11 is communicated with the air outlet 21. Through the arrangement, when flowing, the air flow generated in the compressor firstly collides with the bottom of the second cover body 20, and then flows from the air outlet 21 of the second cover body 20 to the air outlet 11 of the first cover body 10 to be discharged, so that the phenomenon that the air flow directly collides with the rotor from bottom to top to cause instability of the rotor and high noise can be avoided. The first cover 10 and the second cover 20 may be fixed to each other by bolts, fasteners, welding, or the like.
In this embodiment, the air outlet 11 is disposed to be offset from the air outlet 21 in a projection of the first cover 10 to the second cover 20 along the axial direction. That is, the projection of the air outlet 11 to the second cover 20 along the axial direction of the first cover 10 does not overlap with the air outlet 21, so that when the high-speed airflow in the compressor flows upwards, part of the airflow directly passes through the air outlet 21 of the second cover 20 and then collides with the lower surface of the first cover 10, and the airflow is scattered by the collision and then flows out from the air outlet 11 of the first cover 10.
In this embodiment, an upper guide piece 13 and a lower guide piece 14 are disposed at the air outlet 11 of the first cover 10; the upper guide piece 13 and the lower guide piece 14 are disposed at the edge of the air outlet 11 to guide the air outlet direction of the air outlet 11, and the upper guide piece 13 covers a portion of the air outlet 11 on the upper surface of the first cover 10. The lower guide piece 14 is connected to a lower surface of the first cover 10 and covers a portion of the air outlet 11. By the arrangement of the upper guide piece 13 and the lower guide piece 14, most of the air flow does not enter the air outlet 11 from a direction perpendicular to the lower surface of the first cover 10, and most of the air flow is guided by the upper guide piece 13 so as not to directly hit the rotor perpendicular to the upper surface of the one cover. In this embodiment, the upper guide piece is provided with a connecting rib and a flat plate portion, the flat plate portion is connected to the upper surface of the first cover body through the connecting rib, and the flat plate portion and the upper surface of the first cover body are arranged in parallel to each other. One side of the connecting rib is fixed on the edge of the air outlet, the connecting rib extends towards the direction far away from the second cover body, and the other side of the connecting rib is fixed on the edge of the flat plate part. The flat plate portion may block a part of the air flow discharged from the air outlet. The airflow blocked by the flat plate part can only flow along the direction parallel to the flat plate part, and the airflow collides with other airflow flowing out from the air outlet, so that the integrated airflow deviates towards the edge direction of the first cover body, and the airflow cannot directly impact the rotor.
In this embodiment, an included angle between a connecting line between the air outlet 11 and the center of the first cover 10 and the air outlet direction is smaller than 90 °, so that the air flow is not directly rotated.
In this embodiment, the first cover 10 is formed with a first protruding portion 12 protruding upward, and the air outlet 11 is provided at the first protruding portion 12. The second cover 20 is formed with a second protrusion 22 protruding upward, and the position of the first protrusion 12 corresponds to the second protrusion 22, so that the first protrusion 12 is located above the second protrusion 22. The exhaust port 21 is provided at the second protrusion 22. In this embodiment, the first cover 10 is provided with four first protruding portions 12, the second cover 20 is formed with four second protruding portions 22, the first protruding portions 12 and the second protruding portions 22 are arranged in a one-to-one correspondence, and the height of the first protruding portions 12 is higher than that of the second protruding portions 22, so that a certain gap is left between the first protruding portions 12 and the second protruding portions 22 for airflow to pass through. In this embodiment, the first cover 10 is provided with two air outlets 11 symmetrically around the central axis, and the arrangement is such that the pressure of the air flow does not cause the noise reduction cover to be subjected to excessive moment.
The utility model also discloses a compressor, it includes casing, rotor and foretell amortization lid, the rotor with the amortization lid sets up in the casing, the rotor is located amortization lid top, the direction of giving vent to anger of gas outlet with the direction of rotation of rotor is the same.
The utility model discloses a novel amortization lid is through setting up the flat plate portion of guide vane to produce the hindrance to high velocity air, and change the direction that jets out of air current, avoid directly striking the rotor, thereby reduced the noise, improved rotor stability simultaneously.
