Degree.Electrical ball valve is closed when temperature reaches alarm temperature automatically.
The present invention the Instant heating type hot-water heating system of ship utilize heat exchanger principle, thermal medium steam through filter,
Steam valve group upstream end lid, by fresh water in U-shaped heating tube group heated shell, its condensed water is released by hydrophobic valve group enters solidifying
Water collection tank, provides the fresh water with certain pressure, fresh water is inhaled in housing around separator flow by charging tank through connecting line
Heat is received, by the outflow of heater outlet, is used to user, unnecessary fresh water is back to heater housings through hot water circulating pump
It is interior, hot water circulating pump is opened when using, the water in heater is circulated along system lock.Open the outlet valve of heating tube group and enter
Mouth valve, and the open degree of temperature control valve (TCV) is adjusted by the temperature-sensitive thermometer bulb of the electrical temperature regulating valve in heater, control
The flow of system heating medium, reaches the leaving water temperature of auto-control heater。When electrical temperature regulating valve failure, continue to add
Heat, more than the temperature of its setting, when having reached the temperature transmitter design temperature of alarm function, temperature transmitter output signal,
Through the automatic steam off of electrical ball valve on PLC control steam inlet pipeline, and send high temperature alarm signal.
The method for heating and controlling of the Instant heating type hot-water heating system of ship of the present invention, is comprised the steps of：
1st, after normal boot-strap terminates, pump selecting switch is placed in middle position（Automatic running）State, sets delay in touch-screen and opens
Machine time and water pump switching time, " starting " button is then pressed, control system enters automatic running state, and system fresh water is being
Make closed circulation in system.The fresh water pressure and temperature of heater can now be observed.Note：When intake pressure is less than setting value
When, water pump will not be run.
2nd, control system man-machine interface：Heater monitoring interface first is classified as flow of inlet water, pressure in heating system operation
Power, water flow, pressure, temperature, pressure of return water, the data acquisition value of steam pressure, the measuring instrumentss output 4- of onsite application
20mA analog signalses, control system carries out internal conversion according to the range and unit of each instrument, and result finally is shown in into people
Machine interface, the failure if field instrument and control system occur breaking etc., above-mentioned numerical value will show " ##### ", and need attendant
Overhauled, fixed a breakdown.
Monitoring interface second is classified as after the parameter for needing to set, system start, and " delay available machine time " will show green, reach
Start to start 1# pumps after to delay start setting value.Linked during the operation of water pump and electrical ball valve, after water pump is opened 1 minute,
Electrical ball valve will automatically turn on, " ball valve is opened ", and " ball valve pass " is used to refer to the state of electrical ball valve, shows red afterwards in place.Together
When temperature exceed " water outlet overtemperature alarm " value after electrical ball valve will turn off, " ball valve passs " will show red.
" water pump switching time " is the time of each pump operation, example：In automatic running state, the 1# pump operation times reach
After the setting value of " water pump switching time ", 2# pump operations will be automatically switched to, the 2# pump operation times reach " water pump switching time "
Setting value after again will automatically switch to 1# pump operations, two pump groups alternate run within the time of setting.Control system has simultaneously
The function that failure automatically switches, any pump breaks down will automatically switch to another pump operation in operation, sends out simultaneously
It is out of order alarm.When actual run time be less than setting value when, be again started up water pump and added up according to the previous time, i.e., with
The same water pump operation remaining time is automatically switched to another pump again, and now setting value is constant.
By the value of real-time monitoring service data and setting data after the parameter setting such as overtemperature, superpressure, under-voltage, more than setting value
Corresponding setting frame alternately flashes reddish yellow dichromatism afterwards.And can be certainly when overtemperature and superpressure and intake pressure are less than setting value
It is dynamic to close electrical ball valve, and intake pressure, when being less than setting value, water pump also can be out of service.
3rd, the outlet valve of steam-heating pipe group is opened, import valve group is slowly opened（Opening time is no less than 2 minutes）, heating
Medium steam enters heating tube group by temperature control valve (TCV).Water in system and heater is heated.
4th, the parameter such as flow, pressure and temperature on observation touch-screen, the design temperature of temperature control valve (TCV) is 65 DEG C（Setting
Temperature is adjustable）, hot water outlet temperature automatically controls between 60~70 DEG C.
Wherein, the parameter setting of man-machine interface is included：
1st, it is delayed the available machine time：Pressed after energization after " starting " key, water pump is just started after needing to wait for the time of setting, the unit of setting
For minute, the scope that can set of program 0 ~ 9999 minute is set as 1 minute when dispatching from the factory.
2nd, water pump switching time：The time mutually switched for 2 water pumps, the unit set is hour.Setting range 1-
3000 hours,（To extend the service life of water pump, it is proposed that run time is set as one week i.e. 168 hour）, it is set as when dispatching from the factory
100h。
3rd, water outlet overtemperature alarm：When leaving water temperature exceedes the temperature of setting, this key can become the high temperature report of red flicker
Alert state.The scope that program can be set is 0-99 DEG C, and setting range is 70 ~ 90 DEG C during normal work, leaving water temperature when dispatching from the factory
It is set as 80 DEG C.
4th, water inlet low pressure alarming (setting range 0-0.25MPa)：Pressure needed for normal work, if less than this setting value,
This key can become the low pressure alarming state of red flicker.Intake pressure is set as 0.05MPa when dispatching from the factory.
5th, steam low pressure alarming (setting range 0-0.25MPa)：Pressure needed for normal work, if less than this setting value,
This key can become the low pressure alarming state of red flicker.Steam low pressure is set as 0.1MPa when dispatching from the factory.
6th, vapor injection is alarmed：Pressure needed for (setting range 1.0-2.0MPa), normal work, if higher than this setting
Value, this key can become the alarm for high voltage state of red flicker.Vapor injection is set as 1.2MPa when dispatching from the factory.
Above content described in this specification is only illustration made for the present invention.Technology belonging to of the invention
The technical staff in field can be made various modifications or supplement to described specific embodiment or be substituted using similar mode, only
Will without departing from description of the invention content or surmount scope defined in the claims, all should belong to the present invention guarantor
Protect scope.
