Detailed Description
The following describes embodiments of the present utility model in detail with reference to the accompanying drawings, and the embodiments and specific construction processes of the present utility model are given by implementing the embodiments on the premise of the technical solution of the present utility model, but the scope of protection of the present utility model is not limited to the following embodiments.
As shown in fig. 1-4, the damping oil return structure for a refrigerator pipeline according to the present utility model is located near a power plant 1. The power plant 1 is typically a compressor having an inlet connection and an outlet connection. The inlet joint of the power equipment 1 is connected with the inlet pipe 2, an inlet damping bend is arranged at the position, close to the power equipment 1, of the inlet pipe 2, and comprises an inlet U-shaped oil accumulation bend 31 and an inlet U-shaped damping bend 32 which are sequentially arranged along the medium flow direction, wherein the inlet U-shaped oil accumulation bend 31 has the functions of damping and accumulating oil; the outlet joint of the power equipment 1 is connected with the outlet pipe 4, an outlet damping bend is arranged at the position, close to the power equipment 1, of the outlet pipe 4, the outlet damping bend comprises an outlet U-shaped oil accumulation bend 51 and an outlet U-shaped damping bend 52 which are sequentially arranged along the medium flow direction, and the inlet U-shaped oil accumulation bend 31 has the functions of damping and accumulating oil. The openings of the inlet U-shaped oil accumulation bend 31 and the outlet U-shaped oil accumulation bend 51 are upward, and the openings of the inlet U-shaped damping bend 32 and the outlet U-shaped damping bend 52 are downward. Compared with the hard connection of the straight pipe, the design of the U-shaped bent structure is easier to weaken the vibration of the pipeline caused by the vibration transmission and resonance effects of the internal high-speed airflow and the power device. Further, a rubber balancing weight 6 (i.e. an elastic balancing weight and other materials can be selected) is installed on the vertical section of the outlet U-shaped oil accumulation elbow 51, which is close to one side of the power equipment, and the rubber balancing weight can cooperate with the U-shaped elbow to achieve a good damping effect under the working condition of extremely strong vibration amplitude. The openings of the inlet U-shaped oil accumulation bend 31 and the outlet U-shaped oil accumulation bend 51 are upward, and when the high-speed air flow passes through the lowest middle position, the oil mixed therein is accumulated, and the position can be designed into a circular arc shape, a flat shape or a bending structure with the inlet side inclination being larger than the outlet side inclination (respectively shown in fig. 2-4) according to the requirements, and the purpose of smooth oil return can be realized in any shape. Specifically, because the accumulated oil U-shaped bent liquid is stored, the drift diameter of the turning part is reduced, the air flow speed is increased from V1 at the inlet to V2 at the outlet, and the accumulated oil at the liquid storage part is forced to be carried out along with high-speed air flow, so that the purpose of oil return of a pipeline is achieved. The inlet damping bend and the outlet damping bend are respectively arranged at the inlet and the outlet of the power equipment 1, and the specific size is designed according to the actual working condition, thereby being beneficial to saving the material cost and the installation space. Based on this, in the case of satisfying the shock absorption and smooth oil return, it is also preferable to design one of the inlet U-shaped oil accumulation bend 31 and the inlet U-shaped shock bend 32 of the inlet shock bend, the outlet U-shaped oil accumulation bend 51 and the outlet U-shaped shock bend 52 of the outlet shock bend.
It should be noted that, in the description of the present utility model, terms such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element to be referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
