Dynamic Characteristics Research of Self-Swinging Control System with Valve-Controlled Cylinder Device for Liquamatic Fire Water Monitor
In order to satisfy the flexibility requirements of the fire fighting in some particular circumstances, a self-swinging control system with valve-controlled cylinder of the liquamatic fire water monitor was designed. The self-swinging control system was composed of water hydraulic cylinder, water hydraulic valve, water channel connection plate and mechanical feedback device. This controlled system was driven by the pressure water from the monitor body. The water hydraulic cylinder drives the monitor head to swing side by side, consequently, the cover areas of the jet water from the monitor head was increased. At the same time, the modeling and simulation analysis was carried out for the self-swinging control system using the AMESim software, the simulation results show that the self-swinging control system can self-swing in a particular frequency, and the frequency is increasing with the water pressure increasing.
