Among various disasters, the occurrence frequency of fire disasters is the highest, and the fire disasters are one of the main disasters threatening personal safety and social development. When a fire disaster occurs, the fire condition is treated by adopting a reasonable method, and the spread of the fire condition can be controlled in time, so that the occurrence of the fire disaster in a larger scale can be avoided, and the loss caused by the fire disaster is reduced as much as possible.
The water mist fire extinguishing technology is a new high-efficiency fire extinguishing technology. The technology takes water as a fire extinguishing medium, disperses water flow into fine fog drops by using a high-pressure water pump and a specially designed spray head, and efficiently cools and anoxic suffocates the fine fog drops due to evaporation, so that the fire extinguishing effect can be achieved. The application of the water mist fire extinguishing technology is not limited by fire scenes basically, and the water mist fire extinguishing technology can be used for treating solid, oil and gas fuel fires.
The traditional water mist fire extinguishing device utilizes a motor to provide driving force, drives a plug pump to generate high-pressure water flow, and then sprays water out through a spray head to form water mist. Correspondingly, the electric pump driven water mist device needs two main parts, namely a high-capacity power supply control system and a motor drive. The large-capacity power supply control system is extremely susceptible to the working environment. Environmental factors include: the working current, the working voltage, the humidity and the stability of the power grid itself require the use of additional voltage reduction equipment even in some application scenarios. In addition, when a fire disaster occurs, the power supply system is likely to be interfered, so that the system cannot obtain power supply, and further the whole fire protection system is caused to fail. Motor drive then need obtain the power from the switch board, and the motor itself need consider demands such as heat dissipation, can't accomplish very high protection with reasonable cost, and random fault appears easily in the motor of exposing for a long time and the accurate state work.
