Abstract
The utility model discloses a kind of safe operation of the boiler monitoring and alarming system, described system includes 2 pressure transmitters, PLC and alarm；Described 2 pressure transmitters are installed on described boiler, and the output signal of described 2 pressure transmitters is connected to the signal input part of described PLC, and the output signal of described PLC is connected to the signal input part of described alarm.This utility model can find and send warning when boiler liquid level and pressure break down, thus avoid boiler major accident occur in time.
Description
Technical field
This utility model belongs to field of boilers, particularly relates to a kind of safe operation of the boiler monitoring and alarming system.
Background technology
Boiler feedwater is automatically adjusted and automatic regulation system for pressure is that boiler regulates system substantially, they control boiler drum level and drum pressure respectively, boiler liquid level and pressure value are the significant datas that regulation valve automatically controls, the true and reliable safe operation directly influencing boiler of data, guarantee an indispensable regulation system of safe operation of the boiler, regulation valve is controlled by liquid level and pressure signal, when signal occurs false, the action of regulation valve is also wrong, affects the safe operation of boiler.
Utility model content
The problem that this utility model exists for prior art, it is provided that a kind of safe operation of the boiler monitoring and alarming system.
This utility model adopts the following technical scheme that:
A kind of safe operation of the boiler monitoring and alarming system, it is characterised in that described system includes 2 pressure transmitters, PLC and alarm；Described 2 pressure transmitters are installed on described boiler, and the output signal of described 2 pressure transmitters is connected to the signal input part of described PLC, and the output signal of described PLC is connected to the signal input part of described alarm.
According to above-mentioned safe operation of the boiler monitoring and alarming system, it is characterised in that be also equipped with 2 liquidometers on described boiler, the analog signals of described 2 liquidometer collections is connected to the signal input part of described PLC.
The beneficial effects of the utility model: this utility model can find and send warning when boiler liquid level and pressure break down, thus avoid boiler major accident occur in time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Seeing Fig. 1, safe operation of the boiler monitoring and alarming system of the present utility model includes 2 pressure transmitters 1,2, PLC 3 and alarm 4；2 pressure transmitters 1,2 are installed on boiler 5, and the output signal of 2 pressure transmitters 1,2 is connected to the signal input part of PLC 3, and the output signal of PLC 3 is connected to the signal input part of alarm 4.Additionally, the analog signals being also equipped with 6,7,2 liquidometers 6,7 collections of 2 liquidometers on boiler 5 is connected to the signal input part of PLC.
Principle when this utility model uses is as follows: 2 pressure transmitters gather analog signals, do computing by PLC, and 2 pressure values do subtraction, when the absolute value of difference is more than the alarming value preset, output digit signals is reported to the police, and in like manner, liquid level warning is too.Use above-mentioned warning, it is possible to realize boiler pressure and liquid level is true and reliable, so that safe operation of the boiler.
Claims (2)
1. a safe operation of the boiler monitoring and alarming system, it is characterised in that described system includes 2 pressure transmitters, PLC and alarm；Described 2 pressure transmitters are installed on described boiler, and the output signal of described 2 pressure transmitters is connected to the signal input part of described PLC, and the output signal of described PLC is connected to the signal input part of described alarm.
System the most according to claim 1, it is characterised in that be also equipped with 2 liquidometers on described boiler, the analog signals of described 2 liquidometer collections is connected to the signal input part of described PLC.
