Description
Technical field
The present invention relates to a kind of explosion-proof water cooling boosters for anti-explosion diesel engine.
Background technology
Since coal mine down-hole tunnel ventilation condition is limited, and contain methane gas, so being only transformed by Explosion-proof Design
Anti-explosion diesel engine afterwards could be used in underground.Core component of the explosion-proof water cooling booster as anti-explosion diesel engine, performance are excellent
The bad dynamic property, economy and hazardous emission for directly influencing anti-explosion diesel engine.
Chinese patent literature CN203809104U（Application No. is 201320873299.2）Iing is proposed that a kind of water-cooled is explosion-proof can
Become supercharging device, including compressor, intermediate and turbine, it is the exhaust gas inertia impulsive force that is discharged using anti-explosion diesel engine to push away
The indoor turbine of dynamic turbine, turbine drive coaxial impeller, the air that impeller force feed is sent by air cleaner pipeline to be allowed to again
Cylinder of the supercharging into anti-explosion diesel engine.When engine speed increase, the exhaust gas velocity of discharge and secondary speed also synchronous increase, leaf
Wheel just compresses more air and enters cylinder, and boost pressure can bigger.
There are following two points deficiencies for the explosion-proof water cooling booster of the prior art：First, boost pressure is unadjustable, cause to prevent
The boost pressure of quick-fried water cooling booster is when meeting the requirement of anti-explosion diesel engine speed operation air inflow, high-speed working condition boost pressure mistake
Height, air inflow is on the high side, keeps diesel engine row's temperature excessively high, nuisance NOx emission greatly increases, serious to pollute coal mine operation ring
Border.The boost pressure of explosion-proof water cooling booster is when meeting the requirement of anti-explosion diesel engine high-speed working condition air inflow, speed operation supercharging
Insufficient pressure, air inflow are on the low side so that booster it is less efficient.Second is that due on volute inlet flange not only have volute into
Gas port, and there is volute water inlet, when the pad of the water cooled exhaust manifold and explosion-proof water cooling booster junction of anti-explosion diesel engine
When piece damages under high-temp waste gas effect, the water of volute water inlet can enter volute inlet, and last water is caused to enter explosion-proof bavin
Anti-explosion diesel engine is damaged in the cylinder of oil machine, you can poor by property.

See that Fig. 1, the diaphragm valve support 8 are fixedly connected on by bolt 81 on volute body 12；The shell 51, which is fixed, to be connected
It is connected in diaphragm valve support 8.Fig. 1, Fig. 2 and Fig. 6 are seen to Fig. 8, and the booster of the present embodiment adjusts the operation principle of boost pressure
It is as follows：After anti-explosion diesel engine starts, the exhaust gas of cylinder of diesel engine discharge is entered by the air inlet 11-1 of volute 10 in turbine 1
And turbine 15 is pushed to rotate, then companion rotates together the impeller 33 of coaxial compressor 3.With the rotation of impeller 33, then
By being sent into the cylinder of diesel engine after its air inlet 31-1 sucking fresh airs and by exhaust outlet 31-2.
Under normality, the pressure of the gas of the inner cavity 51-1 of the shell 51 of diaphragm valve 5 is normal pressure, in the effect of piston spring 55
Under so that the valve 73 of exhaust gas by-pass valve 7 is in the state of the gas vent of the deflation valve opening 12-1 of closing volute body 12.Work as diesel oil
When the exhausted air quantity of machine cylinder discharge is less, the rotating speed of turbine 15 is relatively low, and the boost pressure of compressor 3 is relatively low, then the valve
Door 73 keeps the state of closing gas vent constant.
With the quickening of cylinder of diesel engine rotating speed, the exhausted air quantity of cylinder discharge also increases therewith, 33 turns of turbine 15 and impeller
Speed increases, and the pressure of compressor 3 also increases therewith, by the outlet tubule 32 on 31 outlet port of compressor casing through silicone tube 4 again
The gas pressure for entering the inner cavity 51-1 of shell 51 through diaphragm valve air inlet pipe 52 is then higher, and the inner carrier 54 of diaphragm valve 5 is in gas
The active force of piston spring 55 is overcome to move down under the action of pressure, inner carrier 54 drives push rod 56 to move down, and is shaken by 56 band of push rod
The shaft 71 for making exhaust gas by-pass valve 7 of arm 6 rotates in the forward direction.Shaft 71 drives pivoted arm 72 to rotate in the forward direction, and pivoted arm 72 then drives valve
The gas vent of 73 dozens of deflation valve opening 12-1 for getting out of the way volute body 12 of door, i.e., so that exhaust gas by-pass valve 7 is opened.At this point, portion
It is directly discharged from deflation valve opening 12-1 by gas outlet 13-1 without turbine 15, to achieve the purpose that control boost pressure,
To realize the reduction of boost pressure.If the exhausted air quantity of cylinder discharge further increases, so that exhaust gas by-pass valve 7 is opened more
It is more, until tending to fully open.With the increasing of 7 opening degree of exhaust gas by-pass valve, more and more exhaust gas direct emissions, to
Limit the quickening of the rotating speed of turbine 15 and impeller 33.
In the state that 7 opening degree of exhaust gas by-pass valve is larger, if the rotating speed of cylinder of diesel engine reduces, by compressor casing
31 outlet tubule 32 through silicone tube 4 again through diaphragm valve air inlet pipe 52 enter shell 51 inner cavity 51-1 gas pressure also with
Reduction, the inner carrier 54 of diaphragm valve 5 then moves up under the action of piston spring 55, and inner carrier 54 drives push rod 56 to move up, then
Make the reverse rotation of the shaft 71 of exhaust gas by-pass valve 7 by the drive rocking arm 6 of push rod 56.The reverse rotation of shaft 71 then drives pivoted arm 72
It reversely rotates, and increases the degree of closure to the gas vent of the deflation valve opening 12-1 of volute body 12 with movable valve 73 by pivoted arm 72,
Namely it may make and finally close exhaust gas by-pass valve 7.In this way, the exhaust gas being discharged by cylinder of diesel engine is completely used for driving turbine
15, to realize the increasing of boost pressure.
