Embodiment 1

[0053] as Figure 1-Figure 4 、 Figure 6-Figure 7 As shown, in the present embodiment there is provided a counterweight device adjustable in-line counterweight, the counterweight device comprising:

[0054] Double-layer casing, along the pipe direction sleeve is located on the outside of the pipe 1 that needs to be counterweighted, the inner diameter of the double-layer casing is greater than the outer diameter of the pipe 1 that needs to be counterweighted, the double-layer casing is composed of the inner tube 102 and the outer tube 101, the inner tube 102 and the outer pipe 101 form a circular counterweight cavity, the pipe that needs to be counterweighted extends in the inner tube 102;

[0055] Separator assembly, arranged between double-layered casings, for separating the ring counterweight cavity 4 out of multiple subweight chambers;

[0056] Vibration detection device for testing line 1 to determine the position of the counterweight to be placed in line 1;

[0057] Magnetic co...

Embodiment 2

[0065] In the present embodiment, there is provided a control method for adjusting the counterweight of the pipeline, the control method for controlling any one of the counterweight devices in Example 1 to counterweight the pipe 1. The control method comprises: detecting the pipeline 1, selecting the position of the maximum vibration value in the pipeline 1 as the position to be counterweighted; determining the subweight cavity corresponding to the position to be counterweighted according to the position to be counterweighted; energizing the magnetic ceiling cover 3 to adsorb the magnetic counterweight material into the corresponding subweight cavity.

[0066]In some alternative ways, the magnetic ceiling cover 3 is energized to adsorb the magnetic counterweight material into the corresponding subweight chamber comprising: opening the flow hole on the separator assembly between the subweight chamber where the magnetic counterweight material is located and the corresponding subwei...

Abstract

The invention discloses a counterweight device with adjustable pipeline counterweight, a control method and an air conditioner. The counterweight device includes: a double-layer casing, which is used to be sleeved on the pipeline that needs counterweight. The inner diameter of the double-layer casing is larger than the outer diameter of the pipeline that needs counterweight. tube and an outer tube, an annular weight cavity is formed between the inner tube and the outer tube, and the pipeline requiring counterweight extends in the inner tube; the partition assembly, which is along the double-layer casing There are multiple sub-weight chambers in the extension direction, and the plurality of partition assemblies divide the annular weight cavity into multiple sub-weight chambers along the extension direction of the double-layer casing, and every two adjacent sub-weight chambers can be separated according to the magnetic The transfer of the weight material needs to be opened or closed; the magnetic weight material is transferably filled in one of the sub-weight cavities; the magnetic top cover is arranged at the end of the sleeve The portion is used to provide the magnetic attraction force required for the transfer of the magnetic weight material between the plurality of sub-weight cavities.

Description

Technical field [0001] The present invention relates to the field of pipeline damping technology, in particular to a counterweight device and control method of adjustable pipe counterweight, air conditioner. Background [0002] At present, in order to avoid pipe resonance, a counterweight is usually placed on the pipeline to change the natural frequency of the pipeline, and the position of the counterweight on the pipeline will affect the change of the solid frequency of the pipeline. At present, the household air conditioning pipeline is equipped with a rubber block, or a damping block pasted to fix it in a certain position of the pipeline, and considering that with the change of the compressor operating frequency, the incentive of the pipeline changes, and the solid frequency of the pipeline is excited changes. Therefore, when the counterweight position is fixed, only the fixed frequency of a certain order pipeline can be improved, and the improvement of the fixed frequency of...
