The YH-XJ series digital fire automatic inspection control cabinet is an important component of the fire extinguishing system, and its performance and daily maintenance management are directly related to our life and property safety. In recent years, the technology, performance, and automation level of fire water supply equipment have made significant progress. However, there is a common problem with various types of fire equipment. When a fire occurs, the fire equipment cannot operate normally after receiving the start signal, which delays the opportunity to extinguish the fire. The main reason for the above phenomenon is that the fire pump is unused for a long time and is in an idle state. In addition, the environment of the pump room is humid. With the passage of time, especially in summer, it is easy to cause moisture, rust, rust death, and abnormal operation of the water pump, which leads to the inability of the fire pump to operate and start when a fire occurs, causing great losses to property and people's safety. According to the functional requirements of GB16806-2006 "Fire Linkage Control System" standard, YH-FXJ fire pump automatic inspection and control equipment has been independently developed and designed.

Model Definition

Product principle

The YH-XJ fire pump automatic inspection control equipment adopts PLC programmable control technology, which is an intelligent control device for patrol inspection of fire pumps. When in non fire state, the fire automatic inspection control equipment performs automatic inspection operation on the fire pump. The automatic inspection cycle can be adjusted from a few hours to hundreds of hours. The cycle clock automatically starts the inspection program and has manual inspection function. During the inspection, the inspection equipment will check and confirm that the main circuit of the fire control cabinet is normal. Then, it will drive the fire pumps at low speed one by one, and the driving power is very small, so the energy-saving effect is achieved. If a fire operation signal is received during the inspection, the inspection equipment will immediately interrupt the inspection operation, and the control equipment will drive the fire pump to enter the fire operation state with power frequency. Only when the next inspection cycle arrives and there is no fire command, will a new inspection operation begin. During the inspection process, if the water pump malfunctions, a fault alarm message will be issued. When there is input overvoltage, undervoltage, power phase loss, phase error, output overcurrent, or short circuit, the inspection equipment will issue an alarm message. The results of this automatic inspection can ensure that the water pump will not rust or die, and can be put into normal operation in the event of a fire.

Product application

The product is suitable for daily inspection of fire pumps, sprinkler pumps and other fire-fighting facilities in public places or large buildings such as hotels, hospitals, large shopping malls, supermarkets, high-rise office buildings, cinemas, museums, exhibition centers, sports venues, airports, train stations, subways, and industrial and mining enterprises. Regular, timed, and high-speed patrol inspections are carried out on the fire pumps, and through automatic inspections, the fire pumps are maintained in a reliable operating state for a long time.

Product Features

The inspection cycle can be set for each inspection time, and the system can automatically determine whether the fire pump can be started normally.

The patrol inspection of the fire water pump adopts low-frequency and low-speed operation, with low power consumption during inspection, and will not increase the pressure of the water supply network or mechanical wear of the pump.

Upon receiving a fire command, it will automatically shut down within 0.5 seconds and switch to the power frequency circuit to ensure the normal operation of the fire pump in case of a fire.

During automatic inspection, the electrical components of the main circuit of the electrical control equipment can be tested to ensure the reliable operation of the electrical control equipment.

The status and operation process of the water pump during operation are displayed by LED and LCD, and the touch screen can set and operate its working status.

□ With fault storage function, equipped with RS232 and RS485 communication interfaces, it can be connected to terminal computers for remote monitoring.

□ It has expansion functions and can be equipped with modules such as circuit inspection, pipeline inspection, GPRS communication, printer and control, bus communication, etc.

□ It has protection functions such as phase error, phase loss, undervoltage, overvoltage, overcurrent, short circuit, etc.

When the fire pump is started, the system adopts interlocking control on the software to ensure that only one pump is running at any time; When a malfunction occurs, the system will automatically provide protection.
