Description
Technical field:
The present invention relates to a kind of unattended automatic control system, be specially adapted to use on the equipment oil filter of industrial circle lubricating oil, hydraulic pressure wet goods type of oil series products.
Background technology:
In order to reduce energy waste; protection of the environment; increase economic efficiency; in fields such as industrial equipment lubricating fluid force feed classes for secondary utilization; that just need to have special equipment again to filter cleaning to used oils; first-selected equipment is vacuum oil-filter; when work, must there is professional to guard protection; its shortcoming is increase staff's labour intensity, and operating ambient temperature to be high, air is dirty; also has multiple uncontrollable factor; therefore it is many unfavorable to bring to enterprise and staff, but also increase the production cost of enterprise, do not reach blowdown and reduce discharging.
How to develop more advanced temperature control, hydraulic self-control, pressure automatic control, unmanned oil filter control system, ensure that the advanced person of futurity industry 4.0 field innovations is targets of those skilled in the art's Continual Improvement and innovation.
Summary of the invention:
Task of the present invention is to propose a kind of recruitment cost that reduces, and enhances productivity, and reduces the unattended automatic control system of one industry oil filter of energy waste.
Task of the present invention completes like this, the unattended automatic control system of a kind of industrial oil filter, it is characterized in that: it comprises single-chip microcomputer, interface on described single-chip microcomputer is connected with man-machine interface by RS485 respectively, the output of described single-chip microcomputer is connected with audible-visual annunciator and electric machine control system, the input of single-chip microcomputer is connected with digital to analog converter, liquid level in oil strain oil tank, pressure and temperature is respectively by liquid level sensor, pressure sensor, temperature sensor collection signal is connected with digital to analog converter by output, the output of described electric machine control system is connected with respectively electric heater, pressure release electromagnetic valve, frequency variable circulating pump and frequency conversion vavuum pump. man-machine interface is by RS485 communication interface and the two-way exchanges data of carrying out of single-chip microcomputer, real-time data acquisition, thereby input single-chip microcomputer by single-chip microcomputer computing equipment running speed and send actuating signal and instruction is inputted by digital to analog converter, thereby self-regulation motor control system. frequency conversion vavuum pump and frequency variable circulating pump regulate running speed automatically, pressure size is opened or closed by pressure release electromagnetic valve, control temperature height by temperature in the automatic regulating tank of electric heater, when break down while reporting to the police autostop make audible-visual annunciator send signal of equipment.
The present invention has following effect: the technical program adopts unmanned, automatic control system is high, improve the production efficiency of enterprise and the waste of the minimizing energy, better again utilize resource, reduce hand labor intensity and artificial quantity simultaneously, greatly improve the economic benefit of enterprise and reduce recruitment cost.
Brief description of the drawings:
Fig. 1 is the control structure block diagram of the technical program.
Detailed description of the invention:
Describe embodiment in detail in conjunction with above accompanying drawing, as shown in Figure 1, further illustrate, a kind of industrial oil filter unmanned automatic control system embodiment of the technical program, RS485 interface on single-chip microcomputer 6 is connected with man-machine interface 5, the output of described single-chip microcomputer 6 is connected with audible-visual annunciator 15 and electric machine control system 7, the input of single-chip microcomputer is connected with digital to analog converter 4, liquid level in oil strain oil tank, pressure and temperature is respectively by liquid level sensor 1, pressure sensor 2, temperature sensor 3 collection signals, be connected with digital to analog converter 4 by output, the output of described electric machine control system is connected with respectively electric heater 11, pressure release electromagnetic valve 10, frequency variable circulating pump 8 and frequency conversion vavuum pump 9.
There is block diagram to find out that man-machine interface 5 carries out the exchanges data of both-way communication by RS485 communication interface and single-chip microcomputer 6, thereby understand more in time the speed and the electric current that show each motor of client's desired data real time inspection, oil strain oil tank internal pressure, temperature, liquid level etc., the digital to analog converter 4 connecting by single-chip microcomputer 6 inputs is by liquid level sensor 1, pressure sensor 2 and temperature sensor 3(measure temperature in oil tank, electrical heating is for dehydration) real-time data acquisition, thereby input single-chip microcomputer by single-chip microcomputer computing equipment running speed and send actuating signal and instruction is inputted by digital to analog converter, electric machine control system 7 is via electric machine control system output frequency conversion vavuum pump 8, frequency variable circulating pump 9, pressure release electromagnetic valve 10, electric heater 11, running speed speed regulates running speed automatically by frequency conversion vavuum pump and frequency variable circulating pump, pressure size is opened or closed by pressure release electromagnetic valve 10, control temperature height by temperature in the automatic regulating tank of electric heater 11, thereby ensure oil filter stability and safety operation in the time of unmanned, when break down while reporting to the police autostop make audible-visual annunciator 12 send signal until fault is got rid of of equipment, control system more again automatically operation go down.
First unmanned oil filter automatic control system is made as manual mode by control system under equipment Light Condition, then set temperature in tank according to the oil strain product performance of oil filter, tank internal pressure, and the running upper limit speed of circulating pump and vavuum pump, then the oil pipe line of filtration is connected, manually boot frequency conversion vavuum pump 8 and frequency variable circulating pump 9 short-time duties and see whether can pump and circulate and whether there is leakage of oil junction; After inspection, unmanned oil filter automatic control system is made as auto state and sees that whether equipment operation is normal again, observe whether low pressure or superpressure of pressure, whether temperature reaches set temperature, then finely tune electric machine control system 7 until device rate is stable automatically moves according to height of liquid level governing speed, if finally observe the so fault-free alarm signal appearance of oil filter operation a few minutes, pressure, temperature, the setting of the errorless rear whole unmanned oil filter automatic control system of pump group normal operation completes, and after this staff can leave scene and be busy with other work. Then a whole set of control device is by the time parameter automatic cycling operating setting in unmanned nurse situation, and then just autostop treats that personnel process; If there is temperature overtemperature in fault time image tank in the middle of equipment, pressure superpressure, electrical fault etc. single-chip microcomputer 6 can send alarm signal rolling flash on man-machine interface 5 and occur prompting user, audible-visual annunciator 12 sends sound and light alarm simultaneously, until fault is got rid of and is resetted, the operation automatically again of unmanned oil filter automatic control system.
