The structural block diagram of the ship fuel oil transfer system is shown in fig. 3, and the heavy oil transfer pump and the light oil transfer pump are reserved for each other. Under normal working conditions, if heavy oil is currently used, the heavy oil conveying pump is required to convey heavy oil in the heavy oil tank to a heavy oil precipitation tank No. 1 or No. 2; if the light oil is currently used, the light oil conveying pump is required to convey the light oil in the light oil tank to a light oil precipitation tank No. 1 or No. 2. The input/output of the light and heavy oil pump is connected with the electrohydraulic remote control valve to be normally closed, when the heavy oil delivery pump or the light oil delivery pump fails and the standby pump is required to start, the data acquisition box receives a failure signal and automatically opens the input/output of the light and heavy oil pump to be connected with the electrohydraulic remote control valve to refute oil in a corresponding oil tank.
In the manual mode, a shipman operates the relevant valve group and pump group on site, and the current state information of the valve group and pump group, including alarm information, can be seen on a console display to judge whether the operation is correct or not and whether the next operation can be performed or not. And the console commander guides the operator according to the current display information.
In the remote control mode, a shipman judges how to operate according to the information of the display, and sends control signals to the related valve group and the pump group through the control console, so that remote control fuel oil conveying is realized.
In the automatic mode, taking the heavy oil mode as an example, the priority of the No. 1 heavy oil precipitation cabin is set to be higher than that of the No. 2 heavy oil precipitation cabin. According to the DGPS/Beidou position information, the current sea area can burn heavy oil. When a certain heavy oil sedimentation tank is detected to have low liquid level (which can be generally set to be 30%), taking the heavy oil sedimentation tank No. 1 as an example, the console controls the heavy oil tank and the electrohydraulic remote control valve of the heavy oil sedimentation tank No. 1 to be opened, the electrohydraulic remote control valves of the other oil tanks are closed, the heavy oil delivery pump operates, and the heavy oil sedimentation tank No. 1 is refuted, when the heavy oil sedimentation tank No. 1 is detected to have high liquid level (which can be generally set to be 85%), the console controls the heavy oil delivery pump to stop, and the electrohydraulic remote control valves of the heavy oil tank and the heavy oil sedimentation tank No. 1 are closed.
When the liquid level of the two heavy oil tanks is low at the same time, the heavy oil tank is preferentially refuted with the No. 1 heavy oil precipitation tank. When a fault signal of the heavy oil delivery pump is detected, the input and output of the light oil pump and the heavy oil pump are opened to be connected with the electrohydraulic remote control valve, and the heavy oil delivery pump replaces the heavy oil delivery pump to deliver the heavy oil of the heavy oil tank to the corresponding heavy oil precipitation tank.
When the type of the oil to be applied is judged to be light oil according to the DGPS/Beidou position information, the oil needs to be switched. If heavy oil is still being used, the system will send out an alarm prompt. The control console sends a stop signal to the heavy oil delivery pump, sends a closing signal to the electrohydraulic remote control valves of the heavy oil tank and the heavy oil precipitation tank, opens the electrohydraulic remote control valves of the light oil tank and the light oil precipitation tank, and then opens the light oil delivery pump to refute the light oil precipitation tank which needs refute oil.
In the automatic process, if the state of the controlled object fed back after the control signal is sent does not change correspondingly according to the control instruction, stopping the next operation, sending an alarm to remind a shipman to check the state of the equipment and perform manual operation.
Further, when two light and heavy oil tanks are respectively used for each other, when the current light and heavy oil tank liquid level is detected to be low (can be generally set to be 5%), the standby light and heavy oil tank electrohydraulic control valve is automatically opened, and the current light and heavy oil tank electrohydraulic control valve is closed.
Finally, it should be noted that: the foregoing description of the preferred embodiments of the present invention is not intended to be limiting, but rather, although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
