Fire Inspection Cabinet Product Overview:
Fire suppression water supply equipment is an essential component of the fire extinguishing system, and its performance and the adequacy of daily maintenance and management directly affect our safety and property. In recent years, the technology, performance, and level of automation of fire suppression water supply equipment have seen significant advancements. However, a common issue with various fire equipment is that upon receiving the start signal during a fire, the equipment fails to operate normally, delaying the fire extinguishing process. The primary reason for this is that fire pumps are often left unused and idle in their regular state. Additionally, due to the humid environment in the pump room, especially during summer, it is easy for moisture and rust to occur, leading to abnormal pump operation over time. Ultimately, this results in the fire pump failing to operate when a fire occurs, rendering it inoperable, and causing significant losses to the nation's property and the safety of the people. Therefore, our company, in accordance with national standards, GB16806-2006 "Fire Linkage Control System" Functional Requirements; self-developed and designedLSK-XFXJ Automatic Fire Pump Inspection and Control Equipment
Product Principle:
Shandong Lansheng Pump Industry producesAutomatic fire pump inspection and control equipment PLC programmable control technology, an intelligent control device for circulating inspection of fire pumps. In non-fire mode, the fire automatic inspection control device performs automatic inspection on the fire pumps. The automatic inspection cycle can be adjusted from a few hours to several hundred hours. The cycle clock automatically initiates the inspection program and also features manual inspection capability. During inspection, the inspection device checks the main circuit of the fire control cabinet and, upon confirming normalcy, drives each fire pump sequentially at a low speed. This operation has a low driving power, thus achieving energy-saving effects. If a fire operation signal is received during inspection, the automatic inspection device immediately interrupts the inspection, and the control device drives the fire pump into fire operation mode at power frequency. A new inspection process is only initiated after the next inspection cycle and without fire commands. During the inspection process, if a pump failure occurs, an alarm will be issued. The inspection device will also trigger an alarm in case of overvoltage, under-voltage, phase loss, phase error, overcurrent, or short circuit. This ensures that the pump does not suffer from rusting or being seized, and can operate normally during a fire.
Product Features
◇ Inspection Cycle: The inspection time can be set individually for each round, and the system can automatically determine if the fire pump can start normally.
The circulation inspection of fire pumps operates at low frequency and low speed. The inspection consumes minimal power, does not increase pressure in the water supply network, and does not exacerbate mechanical wear on the pump.
◇ Upon receiving fire command, the system will automatically shut down within 0.5 seconds and switch to the industrial frequency circuit. Ensuring the fire pump operates normally during a fire.
During automatic inspection, electrical components in 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 pump are displayed on the LED and LCD, with a touch screen for setting and controlling its working state.
◇ Features fault storage function, with RS232, RS485 communication interfaces, capable of connecting to terminal computers for remote monitoring.
◇ Features expandable options, including circuit inspection, pipeline inspection, GPRS communication, printer and control, and summary communication modules.
◇ Equipped with protection functions against phase failure, voltage deficiency, overvoltage, overcurrent, and short circuit.
◇ When the fire pump starts, the system employs interlock control in the software to ensure that only one pump operates at any given time. In the event of a failure, the system will automatically initiate protection.
