Abstract
This invention relates to the field of reciprocating pump hydraulic balance control technology, and discloses a dynamic adjustment method, system, equipment, and medium for reciprocating pump hydraulic balance. The method includes determining the theoretically optimal balance pressure based on the reciprocating pump's structural parameters and operating conditions; acquiring bearing temperature and vibration signals in real time, extracting temperature characteristic values, vibration characteristic values, and temperature change rate, and performing weighted fusion to obtain a bearing load index; tracking the theoretically optimal pressure when the load index is lower than a set value; otherwise, performing incremental PID adjustment based on the deviation; and executing graded protection actions according to the load index's range. This invention evaluates the actual bearing load state through multi-parameter fusion and achieves closed-loop adaptive adjustment, overcoming the shortcomings of existing technologies that cannot reflect the true bearing state and offer only a single evaluation method, effectively extending bearing life and improving operational reliability.
