Products Name:Control Cabinet of Lskb Series of Life, Fire system
Performance description:
LSKB series variable frequency constant pressure water supply automatic control cabinet with AC frequency conversion speed regulation technology and the microcomputer detection, the advanced control technology, the frequency conversion governor, programmable controller and intelligent frequency conversion and constant pressure water supply controller and the introduction of low voltage electrical apparatus combination, full range of flow control of new energy-saving water supply control device of water pump. Variable frequency speed constant pressure water supply cabinet to sudden changes in pressure in the network to set parameters, through computer-controlled inverter output frequency, automatically adjust the pump speed, realize PID closed loop pipe network hydraulic pressure regulation, so as to maintain the end of pipe network constant stress, makes the whole water supply system and continued high efficiency operation: Water consumption increases, the inverter output frequency, the pump speed to accelerate, supply quantity increases; Reduce water consumption, the inverter output frequency is reduced, the pump speed slow down, water supply has been reduced accordingly, so as to ensure that the needs of the user to the water pressure and water quantity. The water supply of constant pressure, do not need to build the high water tower tank, water quality, and therefore less susceptible to pollution two. Water supply system to improve the efficiency and quality of frequency conversion and constant pressure water supply, energy-saving new technology are key national promotion, is a solution of very good modern building water supply.
Using:
1. For high-rise buildings, urban residents, enterprises and institutions of the life, water for fire fighting;
2. Long distance pipeline constant pressure oil system of oil field and oil terminals between;
3. Constant pressure water supply all kinds of water plants and two pumping station;
4. Sewage treatment plants, airports, agricultural irrigation (irrigation) station;
5. Industrial boiler pressure water system, hot water supply system hotel;
6. Hotel, 24 hour uninterrupted supply of hot and cold water; Air conditioning cooling water circulation constant temperature constant pressure control;
7. City square music fountain control etc..
fault phenomenon |
failure cause |
elimination methods |
|
1.No power supply or one or two phase power supply is needed |
Check all phases of power supply and restore power supply |
|
2.Poor contact of ac contactor and burning of coil |
Repair or replace contactors |
can not start |
3. The power switch is not closed, malfunction or damaged |
Close the switch and replace it if the power indicator does not turn on |
|
4. Thermal relay trip or damage |
Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started |
|
Water level is too low |
Put water in the sink |
|
The motor burned |
Repair or replace the motor |
|
1.Line is loose |
Check wiring and tighten connectors |
|
2.Frequency converter malfunction |
Check the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting. |
The manual is normal |
3The frequency converter is damaged |
Repair or replace |
Automatic transmission failure |
4.Pressure switch damage |
Repair or replace |
|
5The pressure transmitter is damaged |
Repair or replace |
|
6.Switch failure |
Repair or replace |
Pump non - suction pressure gauge pointer to beat violently |
Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument |
Check pipeline and bottom valve, refill water diversion. Tighten air leakage |
The pump consumes too much power |
Too much flow, impeller wear |
Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow |
