Among the figure, 1 is that main fuel tank, 2 is that top petrol tank, 3 is that the first main fuel tank fluid level controller, 4 is that the second main fuel tank fluid level controller, 5 is that the first top petrol tank fluid level controller, 6 is that the second top petrol tank fluid level controller, 7 is that first oil pump, 8 is that second oil pump, 9 is that the 3rd oil pump, 10 is that control cabinet, 11 is that main fuel tank alarm, 12 is the top petrol tank alarm.
Embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.Should be appreciated that preferred embodiment has been merely explanation the utility model, rather than in order to limit the protection domain of the utility model.
Fig. 1 does; As shown in the figure: the oil system automatic controller that the utility model provides; Comprise main fuel tank 1, top petrol tank 2, be used to detect the first main fuel tank fluid level controller 3 and the second main fuel tank fluid level controller 4 of main fuel tank 1 pressure signal; And the first top petrol tank fluid level controller 5 and the second top petrol tank fluid level controller 6 that are used to detect the top petrol tank pressure signal; And first oil pump 7, second oil pump 8, the 3rd oil pump 9, control cabinet 10 and alarm, said control cabinet 10 is the PLC controller.Said main fuel tank 1 is connected with first oil pump, 7 pipelines; Said first oil pump 7 is connected with top petrol tank 2 pipelines; Be provided with the first main fuel tank fluid level controller 3 and the second main fuel tank fluid level controller 4 in the said main fuel tank 1; The position of the said first main fuel tank fluid level controller 3 is higher than the position of the second main fuel tank fluid level controller 4; Be provided with the first top petrol tank fluid level controller 5 and the second top petrol tank fluid level controller 6 in the said top petrol tank 2; The position of the said first top petrol tank fluid level controller 5 is higher than the position of the second top petrol tank fluid level controller 6, and the said first main fuel tank fluid level controller 3, the second main fuel tank fluid level controller 4, the first top petrol tank fluid level controller 5 are connected with control cabinet 10 respectively with the second top petrol tank fluid level controller 6.
Said main fuel tank is connected with the second oil pump pipeline, and said second oil pump is connected with the top petrol tank pipeline, and said second oil pump is connected with control cabinet.Said main fuel tank is connected with the 3rd oil pump pipeline, and said the 3rd oil pump is connected with the top petrol tank pipeline, and said the 3rd oil pump is connected with control cabinet.
Said alarm comprises main fuel tank alarm 11 and top petrol tank alarm 12, and said main fuel tank alarm 11 is connected with control cabinet 10 respectively with top petrol tank alarm 12.Said alarm is an audible-visual annunciator.
3 oil pumps can automatically switch through the pressure signal that on-the-spot main fuel tank sends, and guarantee the normal of charge oil pressure; The oil station is on-the-spot installs the fluid level controller with high low-side switch signal output respectively at main fuel tank and top petrol tank, participates in the control of whole oil supply system.The control mode of its realization is following: the fluid level controller of installing at main fuel tank has low liquid level two-stage signal output.The position of the low liquid level signal output of the first order is higher than the position of the low liquid level signal output in the second level.When the low liquid level signal of the first order was exported, control cabinet sent the low alarm signal of main fuel tank liquid level (light, buzzerphone), and this moment, oil pump worked on.When the low liquid level signal in the second level was exported, the oil pump of working quit work.When the liquid level of main fuel tank arrives the position of the high liquid level signal output of fluid level controller, can send the high alarm signal of main fuel tank liquid level equally.The fluid level controller that top petrol tank is installed also must have low liquid level two-stage signal output.When the low liquid level signal of the first order was exported, the field control cabinet sent the low alarm signal of top petrol tank liquid level.When the low liquid level signal in the second level was exported, control cabinet started on-the-spot oil pump automatically, made the lubricant oil of main fuel tank flow into top petrol tank.When the liquid level of top petrol tank reached the position of the high liquid level signal output of fluid level controller, control cabinet can send the high alarm signal of top petrol tank liquid level, and all oil pumps of working simultaneously quit work.
This control system is used for 3 oil pump independent operatings, and promptly the same time has only an oil pump to devote oneself to work.Under the normal condition, first oil pump puts into operation, and when the unexpected accident of generation caused first oil pump to be shut down, second oil pump put into operation automatically, and the 3rd pump puts into operation immediately automatically when second oil pump breaks down stoppage in transit.Automatically switch to the operation of first oil pump if the first oil pump fault is eliminated the back control system, second oil pump or the 3rd oil pump are with out of service.
Explanation is at last; Above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Although the preferred embodiment through with reference to the utility model is described the utility model; But those of ordinary skill in the art should be appreciated that and can make various changes to it in form with on the details, and the spirit and the scope of the utility model that does not depart from appended claims and limited.
