Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, and the embodiments of the present invention includes
But it is not limited to the following example.
Embodiment
A kind of OIL FOR NATURAL GAS COMPRESSOR case system with injector, including fuel tank 1, input end pass through pipeline and fuel tank 1
The first filter 2 of connection, input end are connect with 2 outlet end of first filter and are used for the second mistake of steady air flow by pipeline
Filter 19, the first valve 3 and the second valve 4 that two one end are connect with 19 outlet end of the secondth filter respectively, with the second valve
The Oil-mist fan device of 4 connection of door, the injection apparatus connecting with the first valve 3, the injection apparatus include two one end difference
The third valve 5 and the 4th valve 6 being connect with 3 other end of the first valve, the 5th valve that one end is connect with 6 other end of the 4th valve
Door 7, the steam jet ejector 8 connect with 7 other end of the 5th valve, the 6th valve 9 that one end is connect with steam jet ejector, one end and
The connection of 6th valve, 9 other end and the power steam valve 10 for being in normally open, are connected to the 5th valve 7 and steam jet ejector 8
Between first pressure gauge 11, and first filter 2 input end and outlet end be separately installed with second pressure gauge 17 and
Third pressure gauge 18, wherein staff can judge according to the pressure difference between second pressure gauge 17 and third pressure gauge 18
Whether first filter 2 is in normal condition, if pressure differential range is greater than normal value, needs replacing first filter 2, wherein
Normal range value is the common knowledge in industry, therefore is repeated no more in the present invention.
As shown in Figure 1, wherein the first valve 3 and third valve 5 are air doors, for adjusting the negative of Oil-mist fan 12
Lotus；Second valve 4 and the 7th valve 14 are the inlet valve and outlet valve of Oil-mist fan 12 respectively；4th valve 6 and the 5th
Valve 7 is traditional valve and is in close state under normal circumstances；6th valve 9 is for controlling 8 steam of steam jet ejector
The control valve of dynamics, is in close state under normal conditions；8th valve 16 is the draining valve for controlling oil return tank 15.
When Oil-mist fan 12 works normally, need the first valve 3, the second valve 4, third valve 5, the 7th valve
14, the 8th valve 16, power steam valve 10 and the 9th valve 20 are in the open state, while the 4th valve 6,7 and of the 5th valve
6th valve 9 is in close state, and when the 4th valve 6, the 5th valve 7 and the 6th valve 9 are in close state, is equivalent to steaming
Vapour injector 8 is in off working state, and power steam valve 10 is since the 6th valve 9 is in close state, so in wait work
State, Oil-mist fan 12 works at this time, from the oil in fuel tank 1 by entering the second filter after 2 normal filtration of first filter
In 19, air-flow is stabilized after the filtering of the second filter 19, since the second valve 4, the 7th valve 14, the 8th valve 16 are in and open
State is opened, after the oil after stablizing enters Oil-mist fan 12, the exhaust gas generated through Oil-mist fan 12 then passes through the discharge of the 7th valve 14,
The oil of remaining residue then enters in oil return tank 15, by management by converging into oil in the state that the 8th valve 16 of draining valve is opened
In case 1 or first filter 2, the case where preventing oil leak generation is realized from this.
It needs when stopping transport occurs in Oil-mist fan 12 by the second valve 4, third valve 5, the 7th valve 14,16 and of the 8th valve
9th valve 20 is in close state, and the 4th valve 6, the 5th valve 7 and the 6th valve 9 are opened, other valves, which are in, to be prohibited
State is only pulled, i.e. unlatching steam jet ejector 8.Through the second filter 19 stablize after air-flow through the first valve 3, the 4th valve 6,
5th valve 7 enters in steam jet ejector 8, and the 6th valve 9 by opening enters the power steam under normally open
In valve 10, steam is sent into the external device (ED) connecting with Oil-mist fan 12 by the pipeline being connect with power steam valve 10
(i.e. dotted portion in attached drawing).
It is worked by steam jet ejector instead of Oil-mist fan, saves electricity cost, while avoiding sending out because of Oil-mist fan failure
Raw compressor jumps vehicle, improves the effective running rate of equipment, reduces device stop frequency bring economic loss.And steam sprays
Emitter substitutes Oil-mist fan operation, and it is true to stabilize centrifugal compressor fuel tank internal for the stabilization feature run by steam jet ejector
Empty stability, is discharged the oil gas continuous-stable of the coalescence of fuel tank internal.
Above-described embodiment is only the preferred embodiment of the utility model, is not intended to limit the scope of the present invention,
In every case the design principle of the utility model is used, and carries out the non-creative variation worked and made on this basis, it should all
