Specific embodiment
As shown in figure 1, the utility model discloses a kind of lubricating system with multiple emergency function, including main oil pipe
Pipe 7, emergent oil pipe arm A4, emergent oil pipe arm B15, main oil pipe 10 and controller 8；Main oil pipe arm 7, emergent oil pipe
Pipe A4 and emergent oil pipe arm B15 are connected in turn on main oil pipe 10.
Main oil pipe arm 7 is located at the most upstream of main oil pipe 10, and is joined directly together with fuel tank, including fuel turn manifold pump group and pumps out
Mouth pressure sensor 6, fuel turn manifold pump group includes the main exchange oil pump 1 being arranged in parallel and auxiliary exchange oil pump 2；In the main oil pipe
The elements such as lube oil cooler and filter are additionally provided with arm 7, it is ensured that the quality of lubricating oil.
Emergent oil pipe arm A4 includes a direct current oil pump 3, and is located at the emergent oil pipe arm B15 downstreams in main oil pipe 10
With accumulator group A9 and an oil-feed port pressure sensor 5；Accumulator group A9 includes one or more storages being mutually in series
Can device；Because direct current oil pump 3 is as the direct current emergency bearing oil pump after an AC dump, consider in energy-conservation, its power is less than friendship
Oil pump is flowed, and the oil pump is seldom used, therefore do not design cooler and filter on the emergent oil pipe branch road A4.
Emergent oil pipe branch road B15 includes a top petrol tank 13 and a solenoid valve block 11, and top petrol tank 13 is with a connection
Oil inlet pipe 12 on fuel tank；Solenoid valve block 11 includes a check-valves；Top petrol tank 13 is arranged aloft, the electricity on ground
Magnet valve group 11 is 7～10m；It is located on main oil pipe 10 at the emergent oil pipe branch road B downstreams and there is accumulator group B14；Accumulation of energy
Device group B14 includes one or more accumulators being mutually in series.
Controller 8 and pump discharge pressure sensor 6, main exchange oil pump 1, auxiliary exchange oil pump 2, oil-feed port pressure sensor 5
And direct current oil pump 3 is electrically connected.
The pump discharge of main exchange oil pump 1, auxiliary exchange oil pump 2 and direct current oil pump 3 has a check-valves, prevents pipeline fluid
Backflow.
Each accumulator sap cavity total measurement (volume) in accumulator group B14 always holds more than each accumulator sap cavity in accumulator group A9
Product, the size of sap cavity volume, determine accumulator group storage fluid number and time for using of the accumulator group；Open with oil pump
The dynamic time is corresponding, and accumulator group A9 supply time is most long to be not less than 3s, and auxiliary exchange oil pump 2 is in main oil pipe pressure anomaly 3s
Normal fuel injection can be reached, accumulator group B14 supply time is most long to be not less than 10s, and direct current oil pump 3 shuts down 10s in exchange oil pump
It is interior to reach normal fuel injection.
As shown in Fig. 2 during normal work, fluid being drawn from fuel tank by main exchange oil pump 1 and being supplied to main oil pipe 10, main oil
Pipeline normal pressure in pipe 10 is P1, as shown in A lines in Fig. 2；When main exchange oil pump 1 is damaged or exception occurs, pump discharge
Pressure sensor 6 detects pressure less than setting value P2, and controller 8 is fed back information to immediately, and controller 8 makes immediately sound
Should, control auxiliary exchange oil pump 2 and start, there is the abnormal process that normal pressure is reached to the pipeline of main oil pipe 10 in main exchange oil pump 1
The middle time delay that can produce 1～3s, such as figure t1～t2, now, the pressure in oil pipe is tapered into by P1, due to accumulator group A9 liquid
The presence of chamber inside and outside differential pressure, the fluid in accumulator is automatically replenished into oil pipe, and the switching for major-minor fuel turn manifold pump provides of short duration
(most long to be not less than 3s) fuel feeding and holding pressure stability, auxiliary exchange oil pump 2 replaces main exchange oil pump 1 to work, in main oil pipe 10
Pressure returns to normal pressure P1, in the pressure change such as Fig. 2 of main oil pipe 10 of whole process shown in B lines；When AC dump or
When major-minor exchange oil pump is all abnormal, oil-feed port pressure sensor 5 detects pressure less than setting value P3, feeds back information to immediately
Controller 8, controller 8 is responded immediately, controls direct current pump start, and exchange oil pump exception is occurring to the pipeline of main oil pipe 10
The time delay of 1s～10s, t1～t5 in such as Fig. 2, the same accumulator of accumulator group B14 function can be produced during reaching normal pressure
Group A9, provides of short duration (most long to be not less than 10s) fuel feeding and keeps pressure stability, while notifying main equipment when switching for alternating current-direct current
Prepare to shut down, in the pressure change such as Fig. 2 of main oil pipe 10 in whole process shown in C lines；Direct current oil pump 3 with exchange oil pump 1 all
In the case that appearance is abnormal or fully powered-off, because power-off is shut down, rotary shaft is reduced to low-speed running to main equipment from running up
Until stopping, during this, exchange oil pump and direct current oil pump all can not work, and the pressure in main oil pipe 10 is gradually reduced, instantly
When being preferably minimized pressure value P 4, top petrol tank 13 is started working, and top petrol tank 13 is opened in solenoid valve block 11 using Action of Gravity Field
Check-valves, lubricating oil is supplied into main equipment oil site, the most long supply time of fuel tank is not less than 30min, such as t3～t4 in figure, if
In the case of alterating and direct current all power-off, main equipment is entirely off typically in 30min；Ensure main equipment during shutdown
Still fluid is lubricated its friction part, the main oil pipe oil pressure in whole process changes as shown in D lines in Fig. 2.
General principle of the present utility model and principal character has been shown and described above.The technical staff of the industry should
Solution, the utility model is not restricted to the described embodiments, and this practicality is new for simply illustrating described in above-described embodiment and specification
The principle of type, on the premise of without departing from the utility model spirit and scope, the utility model also has various changes and modifications,
These changes and improvements are both fallen within the range of claimed the utility model.The claimed scope of the utility model is by appended
