Description

수직펌프의 공진 해소용 스티프너{Stiffener for solving resonance problem on vertical pumps}Stiffener for solving resonance problem on vertical pumps}

본 발명은 대용량 수직펌프의 작동 중에 발생되는 공진으로 인한 고진동 문제를 해소할 수 있고 구조적으로 강성을 향상시키고 감쇠를 증가시킬 수 있도록 한 수직펌프의 공진 해소용 스티프너에 관한 것이다.The present invention relates to a stiffener for relieving resonance of a vertical pump, which can solve a high vibration problem due to resonance generated during operation of a large capacity vertical pump, and to improve structural rigidity and increase attenuation.

일반적으로 종래의 경우 대부분의 대용량 수직펌프에 있어서 운전방식이 정격속도를 유지하고, 정격운전속도 근처에서 어느 한 방향으로의 공진으로 인한 고진동이 발생하는 경우 이 특정 한 방향으로만 운전되는 조건을 중심으로 구조의 개선을 위한 제안이 있는 정도로서, 정격속도 운전 중에 발생하는 진동문제를 해소하기 위한 방식으로서는 단순히 진동감쇠용 댐퍼를 설치하거나 아니면 동흡진기를 설치하여 활용하는 정도가 알려져 있다.In general, in the case of the conventional large-capacity vertical pump, the operation method maintains the rated speed, and when high vibration occurs due to resonance in one direction near the rated operating speed, the operation method operates only in this specific direction. As a method for improving the structure, a vibration damping damper or a dynamic reducer is known as a method for solving the vibration problem occurring during the rated speed operation.

그러나, 고용량 수직펌프에 있어서 유량조절을 위한 변속장치인 인버터를 설치하여 운전하는 경우, 일정한 속도가 아닌 다양한 속도에서 운전이 요구되는 상황에서 설비의 특성상 운전 중 여러 속도 및 방향에서 공진으로 인한 고진동 문제가 발생하게 되어 댐퍼나 동흡진기를 설치하여 특정 방향과 특정 속도에서의 고유진동수인 공진을 해소시키는 기존의 방식으로는 이러한 문제점을 해소하기가 어려운 실정이며, 특히 댐퍼를 채택하는 경우엔 장치 내부 유체의 누설이 발생하는 등 관리의 어려움이 발생하고 있다.However, in the case of installing and operating an inverter which is a transmission device for adjusting the flow rate in a high capacity vertical pump, there is a high vibration problem due to resonance at various speeds and directions during operation in the situation where operation is required at various speeds rather than a constant speed. It is difficult to solve this problem by the existing method of eliminating resonance, which is a natural frequency in a specific direction and a specific speed, by installing a damper or a copper reducer, especially when a damper is used. Difficulties in management, such as leaks, are occurring.
