The specific embodiment

Below in conjunction with accompanying drawing the technical scheme of the utility model is done further detailed description:

As shown in Figure 1; The utility model has designed a kind of cargo tank oiling control system; Comprise transmission pump, No. 1 cargo tank and No. 2 cargo tanks, high-order float control H1, low level float control L1, board-like liquidometer and outgate are set respectively in No. 1 cargo tank, high-order float control H2, low level float control L2, board-like liquidometer and outgate are set respectively in No. 2 cargo tanks; The lower end of two outgates is connected with the overflow cabin jointly; Wherein: No. 1 cargo tank also comprises manual shutoff valve HV1 and electromagnetic valve EV1, and said manual shutoff valve HV1 stretches in No. 1 cargo tank, and manual shutoff valve HV1 upper end is connected with the lower end of electromagnetic valve EV1; No. 2 cargo tank also comprises manual shutoff valve HV2 and electromagnetic valve EV2; Said manual shutoff valve HV2 stretches in No. 2 cargo tanks, and manual shutoff valve HV2 upper end is connected with the lower end of electromagnetic valve EV2, and the upper end of electromagnetic valve EV1 and electromagnetic valve EV2 is connected to transmission pump jointly.

As shown in Figure 2, when change-over swith pushes when manual, when using manual shutoff valve HV1 and manual shutoff valve HV2, the injection flow of two cargo tanks can be artificially controlled in the indication of reading the board-like liquidometer on the cabin simultaneously; When change-over swith pushed automatic transmission, subsequent process did not just need engine officer's supervision, and the oil reserve of two cargo tanks is along with main frame or subsidiary engine reduces with oil gradually; When wherein the oil reserve of arbitrary cargo tank dropped to low level, the float control that is contained in low level just can be sensed, and suppose that the oil reserve of No. 1 cargo tank drops to low level this moment; Low level float control L1 just can sense; The passive open contact of going here and there this moment in the control loop can be closed at once, and relay K M1 gets electric adhesive, and open contact KM1 moment is closed; Meanwhile transmission pump gets electric startup, and fuel oil is injected in two cargo tanks through pipeline endlessly; Because two high-order float control H1, two passive normally-closed contacts of H2 are to go here and there control loop after the parallel connection, so fill with when one of them cargo tank; And another cargo tank is can termination of pumping when not filling with, even if because No. 1 cargo tank is filled with earlier, also has only the high-order float control H1 action of No. 1 cargo tank this moment; Passive normally-closed contact open on it, but not disconnection of control loop, pump can continue operation; When No. 2 cargo tank was also filled with, the high-order float control H2 of No. 2 cargo tanks also moved, and the passive normally-closed contact on it also can be broken off; The The whole control loop is just broken off fully at this moment, and pump just can be out of service.

In the preferred implementation of the utility model; Cargo tank oiling control system has increased high-order float control HH1 and HH2 in the top of two cargo tanks; When the oil reserve of No. 1 cargo tank reached high-order, high-order float control HH1 just can move, and this moment, the electromagnetic valve EV1 with its interlock will get electric closure; This branch's oiling passage that leads to the 1# cargo tank just can be ended, and has blocked fuel oil timely and effectively and has flowed to the overflow cabin.Can be by that analogy to No. 2 cargo tanks.

When the low level float control broke down, fuel oil can continue to consume, and when dropping to low low level, low low level float control just can move, and to monitor and alarm system, causes engine officer's attention to signal conveys, safeguards in time.

This overlaps control system, can control a pump simultaneously to two cargo tank oilings.If more cargo tank is arranged, only need the liquid level float ball controller also is installed in other cargo tank, and in control circuit, increase the oiling control system that some relays just can be extended to the many cabins of a pump.
