Fire pump automatic inspection control cabinet is an important part of the fire protection system. The fire linkage alarm system and other equipment determine the fire before the alarm, and one of the ultimate basic goals is to activate the fire extinguishing equipment.
This problem is usually found in all kinds of fire fighting water supply equipment today: When a building has a fire, a large number of fire pumps cannot be started after the signal starts, and the timing of the fire is delayed, resulting in extreme damage to the national property and people's lives. Big loss. The main reason for the above phenomenon is that the fire pump does not start when there is no fire. Over time, the impeller of the pump in the pump will rust and rust in the wet environment of the pump chamber. In view of the above situation, it is necessary to carry out periodic automatic inspections on the pump unit to ensure that the mechanical and electrical properties of the pump are always in good condition. The method of automatic fire detection can fundamentally solve the problem of rusting of water pumps, making fire-fighting equipment "a thousand years of history and temporary use of troops" a reality.
In order to make up for the long-term lazy fire pump, the difficulty cannot start due to corrosion and other reasons. Some national standards also have related requirements, such as "Fixed fire fighting water supply equipment-Part 2: Fire automatic constant pressure water supply equipment" GB27898.2-2011 and " The technical code "fire water supply and fire hydrant system" GB50974-2014 has related descriptions.
The automatic inspection control cabinet for fire water pumps can perform cycle inspection, fixed time and fixed speed inspection on the fire pump. Through automatic inspection, the fire water pump is in a reliable state for a long time.
Commonly used functions of fire pump automatic inspection control cabinet:
1. Inspection function: According to the set cycle, the fire pump will automatically scan at low speed. The speed of a single pump inspection is 300 rpm, and the inspection run time is 10 minutes. (Need to set the time and period), you can automatically switch by switching to check the pointer.
2. The function of automatically exiting the inspection and entering the fire-fighting passage: the inspection cabinet will encounter a fire signal during the inspection process, it will automatically exit the inspection and enter the fire-fighting operation state.
as shown in 3. Alarm and protection functions: The inspection cabinet also has alarm and protection functions for short-circuit, over-current, and motor power failures. During the inspection, it was found that the fault gave out sound and light alarm signals. The alarm system has a fault memory function. The content of the fault and the time when the fault occurred.
as shown in 4. Remote monitoring function: The remote monitoring module can be configured according to user needs, and communicate with the fire center through the bus to realize the purpose of the fire center monitoring system.
5. Pressure test function: The inspection cabinet can also take measures to prevent overpressure according to the fire-fighting pipeline configuration, pipeline system pressure test, pressure water inspection equipment, and pipelines to prevent overpressure, and to safely and reliably set up inspection pressure loop equipment.
6. Mobile phone SMS alarm function: According to the user's needs, the patrol counter can also be equipped with a mobile phone SMS alarm module. When a fault occurs, the fault information will be sent to the user's mobile phone via SMS to prompt the user to deal with it in time.
The fire pump automatic inspection control cabinet is composed of two parts: the main circuit inspection and the pressureless inspection of the fire equipment. It can complete the low-speed automatic detection of the main control circuit and the pump. When the system has no fire command and every switch of the fire equipment system is in automatic state, the intelligent inspection controller will output the inspection instructions to the main circuit one by one for inspection. The detection return signal is taken from the main auxiliary contact of each electrical component. The allowable value of the feedback signal time is not more than 2S. After the main circuit inspection is completed, the inspection controller will generate the next inspection command to the non-pressure inspection device. After receiving the inspection instruction, the equipment will sequentially perform low-speed and no-pressure inspections of the fire pump. During the inspection, the motor speed is low and the system does not generate water pressure. During the entire inspection process, if the device is received.
