Fire pump must need checking control cabinet

1, fire control cabinet overview

fire control cabinet in kaiping water pump frequency conversion water supply equipment factory, on the basis of the application of PLC automatic control technology of inverter output frequency, from surface to adjust pump speed to achieve constant pressure variable automatic water supply. Fire water supply system is a move unnecessary, often brings the problems such as water pump corrosion die pump, real fire accident, often move unnecessary to prepare and should not be used. Inspection control cabinet is suitable for various types of fire water, can improve the reliability of fire water, comply with the requirement of fire code. Solve the overpressure of fire pump power frequency water supply, the problem such as rust die pump, wider application range, is a high-quality, cheap, reliable, and new type of fire water supply equipment.

2, fire control cabinet properties

1) Eliminate pipeline overpressure: power frequency constant pressure variable pump water supply, solve the problem of small water overpressure

2) Pipe pressure regulating function: any constant water pressure, precision is + / - 10% of set pressure

3) Inspection function: manual/automatic checking function ( Can be set arbitrary polling period, inspection time) , solve the problem of power frequency rust die pump, improve the reliability of fire protection system

4) Inspection, in case of fire signal automatically quit, into the fire running state

5) Self-checking and protection: the overpressure, undervoltage, over current, lack of equal power supply fault self-checking, alarm and automatic protection function. To recoverable failures can be manually or automatically eliminate, restore normal operation

6) Fire pump power frequency according to the fire signal automatic start, automatic supplement, automatic into standby pump; Can be automatically according to the pressure change in operation. When the water consumption is big, if a pump water supply shortage, the standby pump can be run automatically added, ensure that fire control pipe network have enough pressure and water

7) Fault and alarm records, inspection record function: for equipment fault, alarm and inspection record form, convenient maintenance and query device status

8) Equipment after high and low temperature, constant humid heat, vibration resistance performance test, in the harsh environment can run normally

9) Control center linkage tank connection function, using the RS485 standard ( Free agreement) Interface with fire host communication, realizes the remote monitoring

10) Using this device can solve the problem of overpressure and rust die pump, DL pump can be used as a fire pump, reduce cost

11) Manual, automatic, remote operation of three way

3, fire inspection control cabinet

fire pump must need inspection & emsp;

fire water supply equipment is an important part of fire control system. Integrated fire alarm system and so on all kinds of automatic fire fighting equipment to judgment until the alarm of fire, finally want to start the fire water supply equipment as one of the fundamental purpose.

today's all kinds of fire water supply equipment generally there is a problem: when building a fire, there are quite a few fire pump can't start after the beginning of the received signal, the fire extinguishing time to delay, to the state property and people's life safety caused great losses.

fire control cabinet of the main reasons for the appeal is fire pump when there is no fire in peacetime is not start, with the passage of time, the water pump in pump room, humid environment inside the pump wheel shaft lotus leaf rust, rust.

on appeal, it is necessary to make periodic review of pump unit, in order to maintain the mechanical properties and electrical performance of the pump is in good condition. This inspection method can solve the problem of water water pump, rust from the like this, make fire fighting equipment find one thousand fight at that time the true reality.

to make up for fire pump sit idle for a long time, can't start the problem caused by corrosion, etc, of the People's Republic of China on public security industry standards on fire control performance requirements of the automatic constant pressure water supply equipment and experiment method ( GA30。 2) Stipulated in chapter 5: fire pump has long been at the running status of equipment should have inspection function.
