Description
One. technical field
The utility model relates to a kind of liquid pipeline burst early warning linkage control device, is suitable for the delivering liquid material application of Xuan Ye enterprise.
Two. background technique
In the production process of enterprise, in liquid pipeline transportation process, often there is pipeline burst phenomenon.The harm of pipeline burst maximum: the one, while finding not in time, can cause a large amount of liquids to reveal, liquid leaks the loss that can cause economically, also can cause secondary harm; The 2nd, the poisonous and harmful medium in industrial pipeline conveying can cause Environment Pollution Event.Mostly take the mode of artificial inspection to go to get rid of the hidden danger of pipeline burst in order to find in time pipeline burst, enterprise.In bargh, the conveyance conduit of seven or eight kilometers, employee, by the inspection of crossing over mountain after mountain, approximately needs a Working day, and facts have proved that pipeline burst phenomenon great majority are to occur time outside artificial inspection.
For addressing the above problem, someone has adopted mechanical pressure switch and digital display pressure switch to realize pipeline burst early warning and interlock, but also there is in actual applications following some deficiency: the one, mechanical pressure switch is because return difference is larger, when operation, in pipeline, instantaneous pressure fluctuation easily causes false alarm, if link startup-shutdown, also need a more complicated circuit design; The 2nd, although digital display type pressure switch has solved the return difference false alarm problem of mechanical pressure switch, start, pressure monitoring, early warning and interlock stopping function, still need a more complicated Logic Circuit Design.
In sum, be necessary to design a set of pressure monitoring accurately, pipeline burst early warning in time, have the equipment of secondary harm realize interlock startup-shutdown and realize employee's Operation and Maintenance liquid pipeline burst early warning linkage control device efficiently to pipe leakage.
Three. summary of the invention
Task of the present utility model is to provide a kind of liquid pipeline burst early warning linkage control device, it can one key start multiple function, can make again that operational monitoring is stable, little investment, maintenance be quick.
For completing above-mentioned task, this uses the following technological scheme of novel employing:
Liquid pipeline burst early warning linkage control device, it comprises pipeline, oil hydraulic pump, start button, stop button, pump switch knob, it also comprises pressure transducer, digital displaying meter, programmable controller, frequency variator, buzzer; By in the program input programmable controller writing; Pressure transducer is arranged on to safety check outer end, oil hydraulic pump waterexit end place; Shielded signal line is connected with pressure transducer and digital displaying meter tenminal block; By the output control terminal sub-connection of frequency variator telecontrol terminal and programmable controller; Buzzer is connected with power supply and programmable controller.
The utility model is because adopted programmable controller, so can have the equipment realization interlock startup-shutdown of secondary harm and realize employee's Operation and Maintenance quick to pipe leakage; Show and converter plant owing to being also provided with pressure, so can precisely monitor pipeline pressure simultaneously; In addition owing to being provided with buzzer, so warning rapidly when pipeline burst, little investment, maintenance are quick.
Four. brief description of the drawings
The concrete structure of model utility is provided by the following drawings.
Fig. 1 is according to the liquid pipeline burst early warning of the one the utility model proposes linkage control device circuti diagram.
In accompanying drawing, each mark represents:
1. pressure transducer 2. digital displaying meter 3. programmable controller 4. frequency variator 5. buzzers
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Five. embodiment
As shown in Figure 1, the liquid pipeline burst early warning of one provided by the utility model linkage control device, it comprises pipeline, oil hydraulic pump, start button, stop button, pump switch knob, and it also comprises pressure transducer 1, digital displaying meter 2, programmable controller 3, frequency variator 4, buzzer 5; By in the program input programmable controller 3 writing; Pressure transducer 1 is arranged on to safety check outer end, oil hydraulic pump waterexit end place; Shielded signal line is connected with pressure transducer 1 and digital displaying meter 2 tenminal blocks; By the output control terminal sub-connection of frequency variator 4 telecontrol terminals and programmable controller 3; Buzzer 5 is connected with power supply and programmable controller 3.
Described digital displaying meter (2) is CH6, and programmable controller (3) is DVP-14ES, and frequency variator (4) is EV2000, an oil hydraulic pump of the corresponding connection in the every unit of frequency variator (4).
When use, liquid pipeline normal pressure value is 4.2Mpa, first digital displaying meter 2 being set to first class pressure early warning value is 4.15Mpa, it is 3.85Mpa that secondary linkage is shut down early warning value, again pump switch knob is forwarded to 1# oil hydraulic pump position or 2# oil hydraulic pump position, after opening oil hydraulic pump waterexit end drain valve, press start button, now the frequency variator 4 of 1# oil hydraulic pump or 2# oil hydraulic pump drives 1# or the running of 2# oil hydraulic pump, when not reaching all the time 3.85MPa at scheduled time interior conduit pressure, now programmable controller 3 sends halt instruction, 1# or 2# oil hydraulic pump autostop immediately, buzzer 5 continues to report to the police simultaneously, be after alarm release is shared with shutdown when pressing stop button, alarm release.If by after oil hydraulic pump drain shut valve, then press start button, pipeline pressure reaches 4.2MPa at the appointed time soon, and now equipment enters normal monitoring running state automatically.When oil hydraulic pump is in the time normally moving; what we were artificial opens oil hydraulic pump waterexit end water discharging valve trace, the now very sensitive decline of pipeline pressure, and pipeline pressure is during lower than 4.15MPa; buzzer 5 continues to report to the police; when water discharging valve continues out greatly, pipeline pressure is during lower than 3.85MPa, and programmable controller 3 sends halt instruction; now oil hydraulic pump is shut down at once; buzzer 5 continues to report to the police, and alert is searched pipeline burst point in time, after fixing a breakdown, can normally move.
