Abstract

A target control method of a liquid-type on-line autobalance device comprises the following steps: extracting a frequency doubling signal of measured equipment from the received real-time vibration signals; calculating the unbalance magnitude and phase of the measured equipment by using the frequency doubling signal; converting the unbalance magnitude to distributed data of liquid in a liquid storage chamber when a balancing device offsets the unbalance magnitude, and forming time control amount of liquid transferring in the liquid storage chamber by liquid infusing or gas driving; according to the unbalance magnitude and phase, dividing the time control amount into the control duration of the liquid storage chamber; and outputting a control command based on the control duration of the liquid storage chamber to control the infusing or flowing of liquid in the liquid storage chamber. The control method can offset vibration, and enables the measured equipment to keep accurate dynamic balance during the operation. The invention further comprises a target control system, which enables the vibration value of the measured equipment to be reduced monotonically, and saves the balance time.

Description

technical field [0001] The invention relates to a control system and a control method, in particular to a control system and a control method of a liquid automatic balancing device. Background technique [0002] During the operation of rotating machinery, rotor imbalance is one of the most common faults. In order to solve this kind of failure, it is often necessary to stop the machine continuously to balance the equipment. The traditional dynamic balancing method uses a dynamic balancing machine for dynamic balancing or complete on-site dynamic balancing, but both methods need to spend a lot of time, manpower and financial resources, and are inconvenient to use. Online automatic balancing technology is a technology that can eliminate equipment unbalance faults online without equipment shutdown. , adjust its unbalanced state at any time, so that the equipment has been running in a good balanced state. At present, this technology has been widely used in the field of high-pr...
