Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: touch-screen 1, PC 2, network HUB3, PLC controller 4, topworks 5, sensor 6, expansion technique of PLC controller 7, expansion topworks 8, extension sensor 9.
Embodiment
Show among the figure that the utility model touch-screen 1, PC 2, network HUB3, PLC controller 4, topworks 5, sensor 6, expansion technique of PLC controller 7, expansion topworks 8, extension sensor 9 are formed.
In the utility model, PLC controller 4 has been selected modular Programmable Logic Controller SIEMENS S7-300 for use, by CPU315, the CP340 communication module, the RS232 Serial Port Line has constituted the host computer of system, and main frame is realized detection and system alarm to on-the-spot pressure by the digital quantity input template.By the start-stop of relay output template control pump group, the switching of valve.Connect touch-screen by the RS232 Serial Port Line and realize man-machine conversation, the technological parameter at scene is set and shown.
In the utility model, establish the HMI watchdog routine in the touch-screen, the HMI watchdog routine can show and actual set value different that correspondingly call the dry oil lubrication control program among the PLC, realization is carried out the control of grease lubricating system to field apparatus according to on-the-spot pipeline actual pressure.
In the utility model, sensor comprises pressure transducer and liquid level sensor, and pressure transducer is installed in the oil feed line, and liquid level sensor is installed in the drier oil fuel tank.The signal output part of sensor connects the signal input part of PLC controller, and the signal output part of PLC controller meets topworks.
In the utility model, topworks comprises lubricating pump, mends fat pump, solenoid valve, and lubricating pump is installed in the drier oil fuel tank, mends the fat pump and is installed in the lubricated pumping plant, and solenoid valve is installed in each pipeline.
The utility model can be finished following major function:
1. each lubricating pump has " man-auto " two kinds of patterns.
Under the manual mode, operating personnel can distinguish No., start-stop or No. two lubricating pumps on touch-screen, when carrying out fuel feeding under manual mode, manually select a line oil feed line A or B, two wires oil feed line C or D are carried out fuel feeding.The supply time of system is not participated in the control of program, after selecting to finish, plays a pump and get final product, and the while can be carried out manual termination of pumping, but when main line pressure when too high or drier oil oil tank liquid level is too low the pump group will be out of service automatically.
Under the automatic mode, operating personnel select on touch-screen automatically, system enters automatic running status, wherein a wire system and two-wire system enter supply time state at interval simultaneously, fuel feeding at interval program picks up counting, and a line, two wires interval time is order (time can directly be set on touch-screen and change) in no particular order.As long as reach setting value wherein arbitrary interval time, lubricating pump starts voluntarily, and system begins to the pipeline fuel feeding, and after the oil feed line pressure controller all reached pressure set points, electrical control cabinet obtained the pressure feedback signal lubricating pump and quits work, commutation.Commutation is to realize that by the charge oil pressure interlocking at this moment, interval time, program picked up counting again.Lubricating pump starts once more voluntarily after reaching setting value interval time, and a line oil feed line A, B begin fuel feeding after exchanging, and two wires oil feed line C, D begin fuel feeding after exchanging.When the oil feed line pressure controller all reached pressure set points, lubricating pump quit work, commutation.At this moment, lubricating system is finished a work period.Periodic duty successively.During auto state, when lubricating pump overload or liquid level were ultralow, lubricating pump quit work at once, and stand-by pump starts automatically.
2. lubricated pumping plant is mended fat and is provided with 1# benefit fat valve and 2# benefit fat valve.Operating personnel can open 1# respectively, and 2# mends the fat valve and mends fat to the drier oil station, but when liquid level was low, fluid level controller can be realized mending fat automatically, and when liquid level was high, fluid level controller can stop to mend fat automatically.When the liquid level superelevation, system produces the liquid level superelevation automatically and reports to the police, and fluid level controller also can realize stopping automatically mending fat simultaneously.
Workflow of the present utility model:
The workflow of this device is exactly by DI digital quantity input integrated circuit board and AI analog quantity integrated circuit board the data at scene to be gathered, to feed back to PLC to each sensor to the current state (running status of oil tank liquid level, each line pressure and system pressure, pump or the like) of each equipment, PLC is through logical operation then, the operational mode that sets according to program, the work purpose is exported the running status that integrated circuit board is controlled lubricating pump, each pipeline electromagnetic valve and mended the fat pump by the DO digital quantity.Realize the automatic operation of system reaching the purpose that lubricating system is lubricated equipment by this control procedure.
