Fire water pump inspection technical parameters
, also Fault records can be queried and inspection status can be fed back in real time.
The starting current, voltage and time can be flexibly adjusted according to different loads to achieve the smallest current [Fire Water Pump Inspection] impact.
In my country's fixed electric fire pump water supply system, one (or more) main pumps are generally used together with one (or more) backup pumps, and a dedicated control cabinet is equipped to control the fire pump. .
The fire inspection device is easy to wire and can be used with the control cabinet produced by any switch factory.
, launched a series of water pump inspection fire control cabinets. ?This control cabinet is based on frequency conversion speed regulation water supply equipment, and applies automatic control technology to adjust the output frequency of the frequency converter
. Just open the valve counterclockwise and water will spray out. Note: If there is an electrical fire, be sure to cut off the power supply.
HC Research predicts that my country's fire protection industry will continue to show a rapid growth trend in the next few years
. Stop the pump after restoring the working pressure. In the event of a fire, the water supply of the pressure-stabilizing pump is insufficient, and the water pressure continues to decline. When the pressure drops, When the pressure is lower than the working pressure,
, it can automatically control the start and stop of the water pump. It is also suitable for control by float switch, limit switch and button remote control.
Domestic water supply pump ( Constant pressure water supply) control cabinet is divided into liquid level control cabinet, pressure control cabinet and constant voltage frequency conversion control cabinet, etc. It can be divided into one use and one standby, two uses and one standby, etc.
Features of fire pump inspection function
It can adapt to capacitive, inductive, resistive and non-linear loads, and can withstand the impulse current generated when the motor starts.
, Chinese【Fire pump inspection】Two kinds of display screens, LCD and true color touch screen, are available for customers to choose
If conditions permit, maintenance is generally required once every six months, mainly to check the frequency converter. Temperature rise and operation status of the cooling fan, contacts and pull-in status of the AC contactor.
This equipment also has the automatic interchange of main and backup pumps. When the main pump fails, the backup pump is automatically put into use.
, once used, it must be effective. At present, the phenomenon of water pump rust and rust caused by long-term use of fire-fighting equipment is very common (up to 10% in some areas, even).
. Timing setting Press the timer r key to enter the timer on function setting. At this time, the timer on and hour bits flash. Press the r key to adjust the hour.
The application of this technology in patrol inspection instruments is helpful to simplify the patrol inspection instruments. At the same time, due to the high performance of the single-chip microcomputer, any damage, whether natural or man-made, will inevitably cause serious losses. In fact, the essential difference between fire-fighting facilities and non-fire-fighting facilities is that the former are not used at ordinary times. Once used, they should ensure their normal operation.
, multi-directional operation, fault information recording, can be output through printer or SMS sending method
, suitable for restaurants, shops, warehouses, underground garages and other places. Ordinary sprinkler heads can be installed directly or hung down on the sprinkler pipe network.
Working principle of fire pump inspection
Automatic inspection of other fire protection equipment: Automatic inspection of fire smoke exhaust fans Inspection: Check the normality of the operating status of the fan
At present, corrosion and rusting of water pumps caused by long-term use of fire-fighting equipment are very common (up to 10% in some areas, even).
Water pump control cabinet control type characteristic words:
, ramp voltage start, constant current soft start optional
, a switching power supply, most control cabinets require a power supply, according to Whether you really need it depends on whether you want this switching power supply.
, Working environment temperature: -+ [Fire pump inspection]
, The impact of large currents directly started by super large motors on the power grid is almost similar to the impact of a three-phase short circuit on the power grid, often causing power oscillations ,
All fuses, switches, isolation equipment, etc. should be installed on the base plate, connected by busbars, and inspected from the front. The handles, buttons and indicator light covers of exterior doors and switches should be coordinated with each other. The protection level of the indoor control cabinet is.
The dual-channel power supply switches and operates regularly to detect the normality of the main and backup power supplies. During automatic inspection
Every time the inspection cabinet inspects the water pump, it opens the solenoid valve seconds in advance, and then inspects the water pumps in sequence to monitor the pressure and flow of the pipeline in real time.
