【 Working Principle 】

The working process of the microcomputer controlled automatic inspection of fire water supply equipment composed of 'XJ-PLC digital intelligent fire inspection controller' is that the fire water supply equipment is a basic component of the prescribed fire water supply system. Although this part does not account for a high proportion of the cost of the entire building's fire protection system, countless experiences and lessons have proven that the success of initial fire suppression mainly depends on the integrity of this part of the equipment. The characteristic of fire water supply equipment is that it is not used normally or even for a long time, and once used, it must play a role. At present, the phenomenon of water pumps rusting and dying due to long-term disuse of fire-fighting equipment is very common.

In non fire state, the fire automatic inspection control equipment composed of XJ-PLC digital intelligent fire inspection controller can automatically inspect and operate the fire pump. The automatic inspection cycle can be selected from several hours to hundreds of hours, and the cycle clock automatically starts the inspection program with manual inspection function. During the inspection, the XJ-PLC digital intelligent fire inspection controller will check and confirm that the main circuit of the fire control cabinet is normal, and then drive each fire pump at low speed to run at low speed. At this time, the driving power is very small, about one percent of the rated power of the pump motor, so the energy saving is significant. Due to the low rotational speed, there will be no pressure increase on the water supply network. If a fire operation command is received during the inspection, this control device will immediately interrupt the inspection operation, and the control equipment will drive the fire pump with power frequency to operate the fire command. Only when the next inspection cycle is completed and there are no fire incidents, will a new inspection operation begin. During inspection, if the water pump malfunctions, a fault alarm message will be given. When input overvoltage, undervoltage, phase loss, output overcurrent, or short circuit occurs, the XJ-PLC controller will send an alarm message to the fire control center. The result of this automatic inspection can ensure that the fire water pump will not rust or die, making it a reality for the fire water supply equipment to maintain troops for a day and use them for a while. This equipment also has functions such as automatic exchange of main and backup pumps, automatic switching of main pump power supply, and automatic switching of backup power supply in case of main power failure. The fire automatic inspection control equipment composed of XJ-PLC digital intelligent fire inspection controller will provide data remote transmission, image monitoring, fault alarm and other functions for all the above functions.
