System, installation and debugging and maintenance are extremely convenient.
Technical scheme, a kind of high-speed centrifugal fan double feeder system, including it is the first check valve, second unidirectional
Valve, the 3rd check valve, the 4th check valve, the 5th check valve, two-way main oil pump, auxiliary oil pump, ball valve, pressure gauge and overflow valve；
Described two-way main oil pump one end is connected with the first check valve and the second check valve respectively, the other end difference of two-way main oil pump
It is connected with the 3rd check valve and the 4th check valve；
3rd check valve is connected with pressure gauge；Described auxiliary oil pump one end is connected with ball valve, and ball valve and the 5th check valve connect
Connect.
Also include fuel tank；One end of second check valve and the 4th check valve is connected with two-way main oil pump, the other end with
Fuel tank connects；One end of the auxiliary oil pump is connected with ball valve, and the other end is equally connected with fuel tank.
3rd check valve and the 5th check valve can carry out fuel feeding by pipeline to high-speed centrifugal fan system.
Beneficial effects of the present invention：The present invention is simple, compact and reasonable for structure；Main oil pump bidirectional modulation is anti-reverse, so as to keep away
Exempt from the damage of bearing, main shaft caused by oil piping system oil-break.Due to the multiple functions such as unidirectional, overflow will be integrated；
Take up space small, functional integration is high, and installation and debugging and maintenance work are brought great convenience.

Embodiment
As shown in figure 1, a kind of high-speed centrifugal fan double feeder system, including the first check valve 1-1, the second check valve 1-
2nd, the 3rd check valve 1-3, the 4th check valve 1-4, the 5th check valve 1-5, two-way main oil pump 2, auxiliary oil pump 3, ball valve 4, pressure
Table 5 and overflow valve 6；
Described one end of two-way main oil pump 2 is connected with the first check valve 1-1 and the second check valve 1-2 respectively, two-way main oil pump 2 it is another
One end is connected with the 3rd check valve 1-3 and the 4th check valve 1-4 respectively；
The 3rd check valve 1-3 is connected with pressure gauge 5；Described one end of auxiliary oil pump 3 is connected with ball valve 4, and ball valve 4 and the 5th is single
To valve 1-5 connections.
Also include fuel tank 7；One end of the second check valve 1-2 and the 4th check valve 1-4 are connected with two-way main oil pump 2,
The other end is connected with fuel tank 7；One end of the auxiliary oil pump 3 is connected with ball valve 4, and the other end is equally connected with fuel tank 7.
The 3rd check valve 1-3 and the 5th check valve 1-5 can be carried out by pipeline to high-speed centrifugal fan system
Fuel feeding.
Operation principle and the course of work of the present invention：
The present invention first starts auxiliary oil pump 3, lubricating oil is successively by auxiliary oil pump 3, ball valve the 4, the 5th before blower fan normally starts
Check valve 1-5, then to system fuel feeding；When system pressure reaches setting a, blower fan starts, at this moment the two-way up time of main oil pump 2
Pin rotates, and lubricating oil is successively by the 4th check valve 1-4, two-way main oil pump 2, the first check valve 1-1, to system fuel feeding.At this moment
When system pressure reaches setting b, auxiliary oil pump 3 is out of service, and oil supply system pressure stability is in prescribed limit.
When blower fan is in standby period（Holding state）, the wind pipe of blower fan is connected with outlet system of air pipe network, now air-out
System pipe network valve is possible to leak, and only air blow back return fan causes impeller to reverse, and drives two-way main oil pump 2 to turn counterclockwise
Dynamic, now lubricating oil passes through the second check valve 1-2, the check valve 1-3 of two-way main oil pump 2 and the 3rd successively, then to system fuel feeding,
The fuel feeding of bearing is ensure that, avoids the damage of bearing, main shaft caused by oil piping system oil-break.
