Abstract
The present invention provides a paraffin removal vehicle automatic control method, which belongs to the oilfield paraffin removal vehicle technology. The present invention improves the defects of the original system. Whether a water tank is provided with water and whether an oil tank is lack of oil can be effectively judged. The stability, the operational performance, the reliability and the safety of the system are improved. The paraffin removal vehicle automatic control device is used by the present invention for memory work. The steps are as follows: step 1 is that the device is started; self-checking is finished; faults are removed and the normal state of the system is achieved; step 2 is that water is supplied, if a water pump is overpressure, the water pump is turned off and restarted after the abnormity is removed; step 3 is that fire is ignited, the fault is removed if any problem happens; firing is conducted again after the fault is removed, the firing is normal and a conflagration is normal; if the conflagration is overheated, the conflagration is turned off; the conflagration is normal to a high temperature; the conflagration is turned off again to a low temperature, the conflagration is started again to normal conflagration and the work is conducted back and forth.
Description
One, technical field: the present invention relates to a kind of oil field wax removal driving skills art, especially paraffin removing vehicle automatic control method.
Two, background technology: at present, control mainly manually to be controlled to be the master at each elephant wax removal car of China, hand push button is controlled the demonstration of the start and stop of each equipment and temperature, pressure, has big, the variety of issues such as the flame detection failure is many, complicated operation of complex circuit, detected temperatures and pressure divergence.When over-temp and over-pressure appearred in system, the very important person shut down for going, and has brought great threat to personal safety.The very important person is for removing to judge water level, oil level, and untimely discovery is shut down if lack of water appears in water tank, will burn out boiler, and damage equipment causes when serious the bursting of boilers to injure operating personnel.Along with electrified technology is applied in the success of traditional petroleum industry equipment, relatively backward on these equipment and technologies, it is not too convenient to operate, and seriously lags behind the needs of petroleum industry.This just requires us to develop the novel paraffin removal unit of the full-automatic operation that is fit to current petroleum industry needs as early as possible, with the requirement of satisfying vast oil field user and the needs in market.
Three, summary of the invention: the purpose of this invention is to provide wax removal car control method for fully automatic, it improves the defective of original system, effectively judge whether water tank has water, fuel tank whether oil starvation, the stability, operability, reliability and the security that improve system, and it has solved the shortcoming of present other technology existence.The object of the present invention is achieved like this, and it is to be formed by connecting by touch-screen, Programmable Logic Controller, pressure transducer, liquid level sensor, fuel level sensor, frequency converter, 24V source of stable pressure, motor, generator, burner, water pump.Generator is powered to main circuit; The 24V source of stable pressure is powered to system; Touch-screen is connected with programmable controller; Input end at programmable controller links to each other with pressure transducer, liquid level sensor, fuel level sensor, temperature sensor by cable; The programmable controller output terminal links to each other with frequency converter by cable, and frequency converter links to each other with motor by cable; Motor is connected with water pump; Programmable controller is connected with burner, and burner is connected with water tank; Wax removal car automatic control program is equipped with in programmable controller inside.
This method is mainly realized by the programmable controller controls program, major function is to judge whether superpressure of boiler water steam by pressure transducer, judge whether lack of water of water tank by level sensor, by having level sensor to judge whether oil starvation and then effectively controlling the start and stop of burner, the operation of control water pump, and are furnished with the dynamic various display parameter values of man-machine interface.
This method is the centralized control to the generator of wax removal car, burner and water pump, temperature and pressure value by monitoring is controlled the large and small fire of burner and the last water yield of water pump, thereby the temperature of combustion of control boiler, can realize the reality of the preceding featheriness burner hearth of burner igniting, igniting, size or conversion and temperature and pressure, man-machine interface operability, visual strong is so that operating personnel's operation.When superpressure and frequency conversion fault appearred in energy realization system, total system quit work, and when overtemperature and combustor fault appearred in system, just combustor quit work, and water pump still works on, and has effectively protected operating personnel's personal safety.
Four, description of drawings: Fig. 1 is a paraffin removing vehicle automatic control method device synoptic diagram
Fig. 2 is the paraffin removing vehicle automatic control method procedure chart
Five, embodiment: in Fig. 1, generator is powered to main circuit; The 24V source of stable pressure is powered to system; Touch-screen is connected with programmable controller; Input end at programmable controller links to each other with pressure transducer, liquid level sensor, fuel level sensor, temperature sensor by cable; The programmable controller output terminal links to each other with frequency converter by cable, and frequency converter links to each other with motor by cable; Motor is connected with water pump; Programmable controller is connected with burner, and burner is connected with water tank; Wax removal car automatic control program is equipped with in programmable controller inside.
In Fig. 2, first step starting outfit, self check finish, fix a breakdown, to reach system normal; Second step supplied water, if the water pump superpressure just cuts out the pump, restarted water pump after eliminating is unusual; The 3rd beans-and bullets shooter fire, if there is problem just to fix a breakdown, igniting again after fixing a breakdown, igniting is normal normal to big fire, if the big fire overtemperature is just closed big fire, high temperature is normally arrived in big fire, close big fire again,, restart big fire and back and forth carry out work to the big fire normal circulation to low temperature.
