Description
Technical field
The utility model relates to a kind of switch board, the special switch board of especially a kind of nitrogen making machine.
Background technology
In recent years, varying-voltage adsorption nitrogen machine is widely applied in many industries, and along with the application of raising and new technology, the new technology etc. day by day of industrial standard, the industry that the high-performance of varying-voltage adsorption nitrogen machine, reliability, convenience are more and more subject to is paid attention to.Existing varying-voltage adsorption nitrogen machine is mostly just simple directly to be controlled nitrogen gas generating system according to enabling signal and runs, this control mode does not carry out fault detect and feedback to nitrogen making machine, also each data that nitrogen making machine runs are not collected and stored, and communication that is unrealized and host computer.
Utility model content
Problem to be solved in the utility model be improve existing nitrogen switch board processed in background technology without detecting, the problem of the function such as feedback and information acquisition.
In order to overcome the above problems, the utility model provides the special switch board of a kind of nitrogen making machine, comprise power supply and PLC, an air switch is connected with between described power supply and PLC, described air switch is connected with PLC with zero line by live wire, the live wire of described air switch is provided with a fuse, described PLC is connected with multiple device, comprise roller actuator, fault detecting point, pressure unit, nitrogen analyser, run feedback interface, emptying device, auxiliary reclay group, running status display lamp and communication interface, described auxiliary reclay group is connected with solenoid valve group and pneumatic valve group in turn, described communication interface is connected with a host computer, described PLC is provided with a touch display, the information of described multiple device controls and display by described touch display.
The special switch board of a kind of nitrogen making machine of the present utility model, the pattern of man-machine interface is adopted to achieve the function such as collection and monitor, unit performance adjustment of field data, and the functions such as unit fault alarm, condition monitoring can be completed, greatly improve convenience and the automaticity of nitrogen making machine use.Be provided with multinomial fault alarm pick-up unit, improve equipment fault analysis ability, have fault alarm and processing capacity, the time that liquid crystal touch screen record trouble occurs and failure cause, for equipment safety operation provides reliably protecting.Switch board data of the present utility model are directly perceived, and simple to operate, automaticity is high and safe and reliable.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of the special switch board of a kind of nitrogen making machine described in the utility model.
Marginal data: 1, power supply; 10, emptying device; 11, touch display; 12, auxiliary reclay group; 13, solenoid valve group; 14, pneumatic valve group; 15, running status display lamp; 16, communication interface; 17, host computer; 2, air switch; 3, fuse; 4, roller actuator; 5, fault detecting point; 6, pressure unit; 7, nitrogen analyser; 8, feedback interface is run; 9, PLC.
Embodiment
Below in conjunction with accompanying drawing, the special switch board of a kind of nitrogen making machine of the present utility model is described further.
As shown in Figure 1, the special switch board of nitrogen making machine of the present embodiment, comprise power supply 1 and PLC 9, an air switch 2 is connected with between power supply 1 and PLC 9, air switch 2 is connected with PLC 9 with zero line by live wire, the live wire of air switch 2 is provided with a fuse 3, PLC 9 is connected with multiple device, comprise roller actuator 4, fault detecting point 5, pressure unit 6, nitrogen analyser 7, run feedback interface 8, emptying device 10, auxiliary reclay group 12, running status display lamp 15 and communication interface 16, auxiliary reclay group 12 is connected with solenoid valve group 13 and pneumatic valve group 14 in turn, communication interface 16 is connected with a host computer 17, PLC is provided with a touch display 11, the information of multiple device controls by touch display 11 and shows.
Arrange air switch can prevent short circuit or overload at power supply place and damage whole circuit.Live wire arranges the effect that fuse also serves protection circuit.During operation, power supply is that PLC is powered, and running status display lamp Chang Liang, touch display shows each unit state.Whether fault detecting point detects complete machine has fault, if having, and system alarm.Pressure unit detects the air pressure of air-flow, realizes the collection of data and shows on touch display.The purity of nitrogen in nitrogen analyser detection system, and Reinheitszahl is presented on touch display.PLC controls emptying device according to the data intelligence of nitrogen analyser simultaneously, realizes defective gas emptying, and acceptable gas stores.Run the running status of feedback interface FEEDBACK CONTROL cabinet, and show related data over the display.Arrange auxiliary reclay group and supporting solenoid valve to rent and pneumatic valve group, quantity and the capacity that can increase switch board contact become expansion interface, facilitate PLC to connect other devices.During operation, communication interface is connected with host computer, realizes the information communication of host computer to PLC, makes host computer can each equipment directly on control PLC controller.
The special switch board of a kind of nitrogen making machine of the present embodiment, adopts man-machine interface pattern, and clear data is directly perceived, and achieves the function such as collection and monitor, unit fault alarm, condition monitoring of field data, and automaticity is high and safe and reliable.
The utility model is not limited to above embodiment and conversion.
