Fire water pump inspection technical parameters
, fire protection When the inspection control cabinet operates in the fire operation mode, it is equipped with an overpressure prevention device. When a fire incident occurs
, three uses and one backup: control,, four water pumps, can work in,, 3 main backup or, main Backup or, Main 3 Backup
When the fire alarm is eliminated, close the gate valve of the pipe network where the sprinkler head is located, and the water pump will automatically shut down when it reaches a certain pressure.
, Constant pressure control of water supply for high-rise buildings, domestic water and fire-fighting water, and closed-loop water for industrial production conditions
Soft start provides a smooth and gradual starting process for the motor, reducing the vibration and noise of the equipment .
The frequency converter outputs low frequency, and the touch screen is used to set the inspection cycle and time of the fire pump, under the control of the programmable controller.
, Fire inspection equipment automatic inspection device control function: complete low-frequency and low-speed self-operated inspection control of fire pumps and spray pumps [fire water pump inspection] and low-speed self-operated inspection of spray pumps, and the inspection cycle is hours
, Working environment humidity: ?No condensation
, Check the status of fire hydrants, spray pump outlet pipe gate valves and one-way valves.
The variable frequency inspection driving power is small, and the operation is efficient and energy-saving. Its power is about .3 of the power of the industrial frequency inspection, which greatly saves power resources.
Features of fire pump inspection function
It has a complete fire communication interface, and the fault sound and light alarm has an interactive operation interface (i.e. communication function) with the fire duty room
There are few inspection items but this This inspection method consumes little power, does not pressurize the pipeline network, and does not require changes to the design of the water delivery pipeline network.
Fire alarm products (linear temperature-sensing fire detectors, household fire alarm products, urban fire remote monitoring products, combustible gas alarm products), etc.
When input overvoltage, undervoltage, phase loss, When the output is over-current or short-circuited, the controller will send an alarm message to the fire center.
During the entire inspection process, if the equipment receives a fire command, the intelligent inspection controller will immediately issue an instruction to stop the inspection and instantly start the fire pump to complete the firefighting task.
Fire departments in various places found during daily fire inspections [fire pump inspections] that many fire water supply equipment were in name only and could not function. The main problems are as follows:
. Innovatively propose dual-mode control technology in the inspection mode of the inspection instrument, so that the inspection instrument has both low-frequency inspection and power-frequency inspection capabilities.
Although this method can complete the test tasks under all working conditions, since manual inspection relies on human behavior, it often has the disadvantages of poor management and unsupervised supervision. Automatic inspection is the guide.
When receiving a fire command during inspection, the inspection will be stopped immediately and the fire pump will be started instantly
. The fire inspection device is easy to install and wire, and can be matched with the control cabinet produced by any switch factory. use.
Working principle of fire pump inspection
Fire sprinkler system is a fire extinguishing device and a widely used fixed fire fighting facility. It has the characteristics of low price and high fire extinguishing efficiency.
The main parameters of the water pump are: flow, expressed in , the unit is 3/, /. Lift, expressed in , the unit is. For clean water pumps, the necessary NPSH parameters are very important, especially when used in suction-type water supply equipment. For submersible pumps, the rated current parameter is very important, especially when used in variable frequency water supply equipment.
The system has a large capacity and complete control functions for fire protection facilities. Suitable for the protection of large buildings.
. With the rapid development of society, in order to comply with market demand, our company absorbs advanced domestic and foreign technologies.
. Features: does not pressurize the fire water supply pipe network and will not affect the pipe network system. Safety does not change the water supply network design.
Terminals used for power incoming and outgoing lines are connected with copper nuts and feed tightening nuts. The size and gap of the terminals should be adapted to the specifications and connecting pieces of the cable.
, whether the automatic inspection cabinet of the fire extinguishing system pump station requires fire protection
, a key card for a non/[fire pump inspection] file server) or a pin mouse plug (for inserting a/file server mouse port).
, Dry alarm valve is used in dry alarm system. Its valve divides the gate into two parts, and the outlet side is connected to the system pipes and nozzles.
, to ensure that the control cables are neatly terminated on site. Each functional unit and external terminal block should be separated by a protruding melamine piece, and a warning mark and functional group mark should be attached.
