An oil management ecosystem equipment purifying and oil discharging self-adaptive system shown in fig. 1 comprises a centrifugal machine 1, an oil tank 2, an oil discharging pipeline 3 and an air suction pipeline 6. The centrifugal machine 1 is connected with a PLC control system, and the PLC control system controls the centrifugal machine 1 to rotate so that pollutants are separated from the oil liquid under the action of centrifugal force; the oil tank 2 is used for containing oil to be treated, and an oil outlet of the oil tank 2 is communicated with an oil inlet of the centrifugal machine 1; the oil outlet pipeline 3 is communicated with the oil outlet of the centrifugal machine 1, the oil outlet pipeline 3 is provided with a pressure sensor 4 and an electric ball valve 5, the pressure sensor 4 is used for detecting the oil outlet pressure of the centrifugal machine 1 and transmitting pressure data to a PLC control system, and the PLC control system controls the opening of the electric ball valve 5 to control the oil flow of the oil outlet pipeline 3 so as to enable the centrifugal machine 1 to achieve the optimal oil purifying efficiency. The suction pipeline 6 is connected with the centrifugal machine 1 and the oil tank 2, the suction pipeline 6 is provided with a self-priming pump 7 and a one-way valve 8, and the self-priming pump 7 is used for absorbing free gas in the centrifugal machine 1 so as to maintain the stability of the pressure in the centrifugal machine 1 and further maintain the purification efficiency of the centrifugal machine 1.
In an embodiment, the oil to be treated in the oil tank 2 is conveyed into the oil inlet of the centrifugal machine 1 from the oil outlet of the oil tank 2 through an oil conveying pipeline. The centrifuge 1 rotates at a high speed to separate contaminants mixed in the oil from the oil. The treated oil flows out from the oil outlet pipeline 3, and the purification treatment process of the oil is realized.
The longer the oil remains in the centrifuge 1, the higher the quality of the oil after being treated by the centrifuge 1. However, the longer the oil remains in the centrifuge 1, the slower the oil flow rate of the oil in the centrifuge 1 of the same size, and the efficiency of the centrifuge 1 for treating the oil is lowered. In order to ensure the oil treatment quality and improve the oil purification efficiency of the centrifugal machine 1, a large number of experiments show that the centrifugal machine 1 has the optimal oil purification efficiency when other factors of the centrifugal machine 1 are unchanged, and in order to control the oil purification efficiency of the centrifugal machine 1, the centrifugal machine 1 maintains the optimal oil purification efficiency, and a pressure sensor 4 and an electric ball valve 5 are designed on an oil outlet pipeline 3 to control so that the centrifugal machine 1 can always maintain the optimal oil purification efficiency.
In an embodiment, various data of the centrifuge 1 are input in advance in a PLC control system, and the PLC control system calculates an optimal oil purifying efficiency of the centrifuge 1 in a current state and calculates an oil pressure value in the oil outlet line 3 in the case of the oil purifying efficiency. The PLC control system adjusts the opening degree (opening degree) of the electric ball valve 5 by comparing the theoretical oil pressure value of the oil outlet pipe 3 with the oil pressure value of the actual oil outlet pipe 3 provided to the PLC control system by the pressure sensor 4. When the actual oil pressure value is larger than the theoretical oil pressure value, the opening of the electric ball valve 5 is increased, the oil flow in the oil outlet pipeline 3 is increased, and the oil pressure value is reduced until the actual oil pressure value is equal to the theoretical oil pressure value; when the actual oil pressure value is smaller than the theoretical oil pressure value, the opening of the electric ball valve 5 is reduced, the oil flow in the oil outlet pipeline 3 is reduced, and the oil pressure value is increased until the actual oil pressure value is equal to the theoretical oil pressure value. The oil pressure value in the centrifugal machine 1 is adjusted so that the centrifugal machine 1 maintains optimal oil purifying efficiency. It should be noted that the oil pressure value in the oil outlet line 3 detected by the pressure sensor 4 is equal to the oil pressure value in the centrifuge 1.
In an embodiment, during the centrifugal purification process of the oil liquid by the centrifugal machine 1, free gas can be separated out from the oil liquid, and along with the continuous operation of the centrifugal machine 1, the free gas in the centrifugal machine 1 is continuously gathered, and when the free gas reaches a certain amount, the pressure value in the centrifugal machine 1 can be influenced, so that the flow in the centrifugal machine 1 is unstable, and the continuous treatment of the oil liquid by the centrifugal machine 1 is not facilitated. An air suction pipeline 6 is connected between the centrifugal machine 1 and the oil tank 2, and a self-sucking pump 7 is arranged on the air suction pipeline 6, and after a certain amount of gas is separated out from oil, the self-sucking pump 7 is started to suck the free gas in the centrifugal machine 1 into the oil tank 2. When the self-priming pump 7 pumps out free gas in the centrifuge 1, a small amount of oil is pumped out into the oil tank 2, i.e., a small amount of oil is also present in the suction line 6. The oil pumped from the centrifuge 1 by the self-priming pump 7 basically does not affect the oil purifying efficiency of the centrifuge 1, and the oil pumped from the centrifuge 1 by the self-priming pump 7 enters the oil tank 2 again to be mixed with the oil in the oil tank 2, and waits to be purified by the centrifuge 1.
Preferably, a temperature sensor 9 is arranged in the centrifugal machine 1, and the temperature sensor 9 transmits temperature data in the centrifugal machine 1 to the PLC control system in real time, so that the PLC control system can calculate an optimal oil pressure value at the temperature according to the temperature in the centrifugal machine 1.
In one embodiment, the temperature sensor 9 is provided to detect the temperature of the oil in real time because the influence of the temperature of the oil on the flow rate of the oil is relatively large. The temperature sensor 9 transmits temperature data of oil in the centrifugal machine 1 to the PLC control system in real time, and the PLC control system calculates an oil pressure value required for maintaining the optimal oil purifying efficiency of the centrifugal machine 1 according to the temperature data at the moment and adjusts the opening of the electric ball valve 5 according to the oil pressure value at the moment.
Preferably, the self-priming pump 7 is internally provided with a time controller which controls the timing operation of the self-priming pump 7. The method realizes the timed absorption of free gas in the centrifugal machine 1 and avoids the influence of excessive free gas aggregation on the stability of clean oil of the centrifugal machine 1.
In an embodiment, when the free gas in the centrifuge 1 accumulates to a certain amount, the self-priming pump 7 is started to pump the free gas, and stops pumping after a first set time, and when a second set time is reached, the self-priming pump 7 is started to pump the free gas in the centrifuge 1 again, and the pumping time is the first set time, so as to maintain the stability of the centrifuge 1. The first set time and the second set time are obtained through a large amount of experimental data according to the specific condition of the centrifugal machine 1. When the self-priming pump 7 pumps the free gas in the centrifuge 1, the pressure in the centrifuge 1 changes greatly, and the opening degree of the electric ball valve 5 controlled by the PLC control system changes greatly, so as to maintain the optimal oil purifying efficiency of the centrifuge 1.

The technical principle of the signal generator 10 belongs to the prior art and is not described in detail here.
Preferably, the PLC control system comprises a PID controller, and the PID controller adjusts the switching speed and the response time of the electric ball valve 5 by controlling the time length, the integration time and the differentiation time, so that the oil flow speed is adjusted linearly, and the damage to the stability of the pressure in the centrifugal machine 1 caused by the overlarge change of the flow speed is prevented.
Preferably, the PLC control system comprises a touch display screen and an audible and visual alarm, and the touch display screen is beneficial to information acquisition and input control of the PLC control system for workers. The audible and visual alarm is connected with the pressure sensor 4 in a signal way, and when the pressure data of the pressure sensor 4 is abnormal, the audible and visual alarm gives an alarm signal to prompt a worker to check and correct before.
Preferably, the PLC control system is connected to the control room through a data transmission line, so that the control room can conveniently archive and analyze the data information in the PLC control system.
In an embodiment, the PLC control system can transmit all received data to the control room, and the staff in the control room performs analysis and calculation according to the data transmitted by the PLC control system, further study on factors affecting the oil purifying efficiency of the centrifuge 1, and can revise the bottom data of the PLC control system through the control room.
When the oil product management ecological system is adopted to purify the oil self-adaptive system, the opening of the electric ball valve 5 is regulated according to the oil pressure in the centrifugal machine 1 by installing the pressure sensor 4 and the electric ball valve 5 at the oil outlet pipeline 3 of the centrifugal machine 1 so as to control the oil flow in the oil outlet pipeline 3, and further the centrifugal machine 1 achieves the optimal purification efficiency of oil.
