Specifically, when the pressure value of the oil storage tank 20 detected by the first pressure transmitter 32 is greater than the third pressure value, the control system controls the second valve 60 to close, so that the pressurizing device 30 stops supplying high-pressure gas to the oil storage tank 20, and the pressure in the oil storage tank 20 is prevented from being too high; when the pressure value of the oil storage tank 20 detected by the first pressure transmitter 32 is less than or equal to the fourth pressure value, the control system controls the second valve 60 to open, so that the pressurizing device 30 provides high-pressure gas to the oil storage tank 20, and the oil storage tank 20 is prevented from being affected by too low pressure in the oil storage tank 20 to replenish the high-level oil tank 10. In the present embodiment, the first pressure transmitter 32 connected to the control system is disposed in the oil storage tank 20, so that the pressure in the oil storage tank 20 can be automatically detected and adjusted.
On the basis of the above embodiment, the oil storage tank 20 is further provided with a second pressure transmitter 25 electrically connected with the control system, and the second pressure transmitter 25 is arranged on the top of the oil storage tank 20 and used for detecting the pressure of the oil storage tank 20 and transmitting the detected pressure signal to the control system.
As can be seen from the above description, the control system is also electrically connected to the first pressure transmitter 32, so as to prevent the first pressure transmitter 32 from malfunctioning and transmitting a wrong detection signal to the control system, so that the control system can issue a wrong command according to the wrong detection signal, and the control system can not effectively adjust the pressure of the oil storage tank 20. Therefore, the control system of the present embodiment is electrically connected to the first pressure transmitter 32 and the second pressure transmitter 25, the control system receives the pressure signal detected by the first pressure transmitter 32 and the pressure signal detected by the second pressure transmitter 25 at the same time, when the pressure value detected by the first pressure transmitter 32 and the pressure value detected by the second pressure transmitter 25 are both greater than or equal to the third pressure value preset by the control system, and the pressure value detected by the first pressure transmitter 32 and the pressure value detected by the second pressure transmitter 25 are equal to each other or the difference between the two values is within the preset error range, the control system can control the second valve 60 to close, and stop delivering the high-pressure gas to the oil storage tank 20.
When the pressure value detected by the first pressure transmitter 32 and the pressure value detected by the second pressure transmitter 25 are both smaller than or equal to the fourth pressure value preset by the control system, and the pressure value detected by the first pressure transmitter 32 and the pressure value detected by the second pressure transmitter 25 are equal or the difference between the two values is within the preset error range, the control system can control the second valve 60 to open, and deliver high-pressure gas to the oil storage tank 20, so that the pressure of the oil storage tank 20 is prevented from being too low. In the embodiment, the control system can only close or open the second valve 60 by setting multiple judgment conditions in the control system, so that the misjudgment risk of the control system is reduced; the reliability of the automatic oiling system is improved.
As shown in fig. 5, the oil storage tank 20 is further provided with a pressure gauge 24 and a liquid level gauge 21, and the pressure value and the corresponding liquid level height of the oil storage tank 20 at this time are obtained by observing the states of the pressure gauge 24 and the liquid level gauge 21; and then by obtaining the pressure values of the first pressure transmitter 32 and/or the second pressure transmitter 25 and the liquid level height of the liquid level transmitter 22, comparing the data, and judging whether the first pressure transmitter 32, the second pressure transmitter 25 and the liquid level transmitter 22 have faults or not, the reliability of the automatic oiling system can be further improved.
In this embodiment, the automatic refueling system further includes a manual valve 31, the manual valve 31 is connected to the second pipeline, and the manual valve 31 is connected in parallel with the second valve 60. Specifically, the manual valve 31 is further arranged on the second pipeline, the manual valve 31 is located on a branch, and two ends of the branch are respectively connected to the left end and the right end of the second valve 60, that is, the second valve 60 and the manual valve 31 are connected in parallel, when the oil storage tank 20 cannot be pressurized when the second valve 60 fails, the manual valve 31 can be opened, so that compressed air of the pressurizing device 30 bypasses the second valve 60 through the branch and is transmitted to the oil storage tank 20, pressurization of the oil storage tank 20 is completed, lubricating oil in the oil storage tank 20 is smoothly pressed into the high-level oil tank 10, and reliability of the automatic oiling system is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
