AI Technical Summary

Technical Problem

Existing condensate pumps face the problem of complex vibration. Traditional vibration absorbers are difficult to install and have poor vibration reduction effect. Single-layer damping structures cannot effectively dissipate broadband vibration energy, and the damping layer is a fixed design that cannot be dynamically adjusted.

Method used

The system employs a layered, stacked double-layer damping structure, coupled with the counterweight and upper-layer damping components. The lower-layer damping components absorb low-frequency vibrations, while the upper layer suppresses high-frequency resonances. The isolation components coordinate phase differences, thereby achieving broadband vibration suppression. Furthermore, the modular installation method disperses local stresses.

Benefits of technology

It effectively covers a wide frequency band of vibration suppression, improves structural reliability and ease of installation, solves the problems of difficult installation and insufficient life of traditional vibration absorbers, and significantly improves the operational stability of condensate pumps.
