0: Overview

Currently, due to the widespread rusting and death of water pumps caused by long-term disuse of fire-fighting equipment, it is solely achieved through manual methods to control the water pumpsdetectionIt has been proven multiple times that reliable operation of fire pumps cannot be guaranteed. This article introduces the application of multi power transmitters in the inspection system of fire water supply equipmentproductGood application results have been achieved, reducing the possibility of fire water supply equipment failure.

1: Application of multi power transmitter in fire inspection equipment

The fire water supply equipment is a basic component of the fixed 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 extinguishing initial fires 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, but once it is used, it must come into play.

In response to this phenomenon, relevant departments have formulated a mandatory document called "Performance Requirements and Experimental Methods for Fixed Fire Water Supply Equipment", which clearly requires fire equipment to have automatic inspection functions. The document clearly stipulates that:

1. The equipment should have automatic and manual inspection functions, and its automatic inspection cycle should be able to be set as needed.

2. The fire pump is controlled to start and operate one by one, with each pump running for no less than 2 minutes.

3. The equipment should be able to ensure that fire safety is encountered during the inspection processsignalAutomatically exit the inspection and enter the fire protection operation state.

4. During the inspection, if any faults are found, there should be sound and light alarms. Equipment with fault memory function should record at least 5 fault information, including the type of fault and the time of occurrence, and its display should be clear and easy to understand.

During the low-frequency inspection cycle, the fire inspection system follows theprogrammingPre entering the program to start the water pump at low frequency can test the reliability of the water supply system. All devices are operating at low frequency, inspected bycontrollerDetermine the operating status of the water pump. If a fire occurs, immediately stop the inspection and switch to the firefighting process for extinguishing the fire. The multi power transmitter provides the controller with various types of electrical parameters, such as current, voltage, power, power factor, etc., to make various judgments for the controller, such as overvoltage, undervoltage, phase loss protection, etcmotorProvide comprehensive information on error messages such as blockage. During inspection, the fire inspection controller will check and confirm that the main circuit of the fire control cabinet is normal, and then drive each fire pump 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 energy saving is significant. Moreover, due to the low speed, it will not increase the pressure of the water supply network.

2: Introduction to multi battery transmitter

The multi battery transmitter has the following characteristics: The multi battery transmitter is aintelligenceElectrical parameter transmitters can replace a series of transmitters such as current, voltage, power, and power factor in the past, reduce system costs, facilitate on-site wiring, and improve system reliability. It can also be hung on the same 485 bus with control modules from other manufacturers, and is easy to program with computers. Customers can build their own measurement and control systems according to their needs. The multi battery transmitter adopts electromagnetic isolation andoptoelectronicsIsolation technology,power supplypower supplyThree party isolation of input and output signals.

3: Conclusion

The normal use and operation of fire-fighting equipment are related to the protection of human life and property. The previous extensive method of relying on manual inspection of fire-fighting equipment is no longer suitable for the needs of modern firefighting. By setting up regular automatic low-speed inspections of the fire pump, it is possible to prevent corrosion and rust death of the fire pump, as well as to remove moisture from the motor, ensuring that the equipment can operate normally immediately upon receiving the start command. The multi power transmitter provides circuit current, voltage, power, power factor and other information to the inspection controller in the fire inspection system, enabling the controller to determine whether the circuit has overvoltage, undervoltage, phase loss protection, motor stalling and other fault information, achieving the goal of reducing risks.
