摘要
论述了采用可编程PLC控制器和变频器调节电机转速,实现对消防供水系统压力进行自动控制调节,当火情发生时消防泵自动启动,使水压在短时间内达到要求,从而保持相对稳定的压力,满足实际消防用水的要求,大大提高了消防系统正常运行的可靠性,可避免重大事故的发生。
The automatic control on pressure of fire-fighting water supplying system is realized,by applying for the programmable controller PLC and conventer to control the motor speed.When fire is happens,the fire-fighting pump will start-up automatically and water pressure can reach the required value in very short time and maintain relative constant,so that the real fire-fighting water requirement can be satisfied.Therefore the reliability of fire-fighting system in normal operation can be guaranteed and the great accident can be avoided.
