Description
Technical field
The present invention relates to place the container of immersed pump, relate in particular to a kind of pump pond natural frequency adaptive technique.
Background technique
Need to be immersed under the liquid of certain liquid level during the immersed pump normal operation, therefore need to be placed in the specific container, such container is referred to as " pump pond " usually, and existing pump pond generally is the rectangle and circle cylindrical container.In the actual using process, the problem of appearance has: the first, need High Rotation Speed during the immersed pump normal operation, and will inevitably cause the vibration in pump pond, the pump pond is subject to vibrational excitation for a long time, fatigue crack occurs, and the life-span shortens greatly, threatens safety in production; Second, according to actual user demand, same pump pond usually needs to place the immersed pump of different model or different rotating speeds, and the natural frequency in same pump pond is certain, its natural frequency can't be avoided the immersed pump under the various rotating speeds, and the pump pond is easy to resonate with immersed pump so, in case resonance phenomenon occurs, can be significantly life-span of loss pump pond and immersed pump, and have serious potential safety hazard; The 3rd, the vibration in pump pond can be sent noise, produces noise pollution.For the problems referred to above, existing solution is, the first, the pump pond simply is fixed by bolts to ground, and reaching the purpose that reduces forced vibration, but poor effect must be become flexible after bolt bearing a period of time; The second, the situation of resonance occurs for pump pond and immersed pump, usually redesign the pump pond or change the immersed pump of other rotating speeds, avoiding both natural frequencys, but cause the wasting of resources, cost increases.
Summary of the invention
