Technical field
The present invention relates to a kind of stable-pressure device, more particularly to a kind of vacuum tank of fuel oil air driven pump.
Background technology
The pumping mode of current engine fuel has two kinds：Electrodynamic pump is pumped and air driven pump pumping.
Because the voltage and power output of electrodynamic pump are all more stable, so the pressure of electrodynamic pump output fuel oil is relatively stablized,
Disclosure satisfy that the requirement to fuel delivery in engine working process.At present, it is in the engine in laboratory to use electrodynamic pump more.But
It is that electrodynamic pump needs to carry out special circuit connection and arrangement, and the meeting in the light component fuel oil such as pump gas when in use
Potential safety hazard is produced, cost is considerably increased again according to explosion-proof electric pump, and install extremely inconvenient with dismounting.
Air driven pump have the advantages that low price, good dynamic property, using safety, small volume, be easy to arrangement, be widely used in
In the high-volume cargo handling process of fuel oil.If air driven pump is used for the oil supply system of laboratory engine, occur that charge oil pressure becomes
The problems such as changing excessive, instability of flow, makes the component working exception such as fuel flowmeter, engine, fuel pump, influence engine
Normal operation, in the winter time due to containing vapor in compressed gas, when fuel flow is smaller, it may appear that between pneumatic pump work
Time of having a rest is more long, and the precipitation for causing vapor causes air driven pump or gas supply line to freeze, fuel cut-off.
Utility model content
The utility model provides a kind of vacuum tank of fuel oil air driven pump.
The utility model proposes fuel oil air driven pump vacuum tank, including tank body 1, fuel filler 2, be arranged in tank body 1
The central baffle 3 in portion, fuel outlet 4, have between the top and bottom of the central baffle 3 and the top and bottom of tank body 1
On the tank body 1 of interval, the fuel filler 2 and the centrally disposed both sides of dividing plate 3 of fuel outlet 4.
The pref. cylindrical tank body of the tank body 1.
The bottom of the fuel filler 2 is preferably above the top of fuel outlet 4.
The top of the central baffle 3 is preferably above the liquid level of the input fuel oil of tank body 1.
The top of the central baffle 3 is preferably above fuel filler 2, fuel outlet 4.
The preferred vertical of the central baffle 3 is set.
The bottom of the tank body 1 is preferably provided with oil return opening 5.
The fuel filler 2 is connected with the fuel oil air driven pump 6 of input fuel oil.
The oil return opening 5 is preferably connected with fuel oil air driven pump 6 or fuel oil intake pipeline.
The top of the tank body 1 is preferably provided with pressure gauge 7, can observe the pressure of tank body 1.
The utility model effectively reduces the fuel pressure fluctuation in fuel oil air driven pump output circuit, can provide stabilization
Fuel delivery, it is to avoid fuel oil air driven pump winter incident freezeout and the issuable potential safety hazard of electrodynamic pump, expands
The big use scope of fuel oil air driven pump, effectively increases the stability and security of engine fuel system.

Specific embodiment
Below in conjunction with Figure of description, specific embodiment of the present utility model is made an explanation.
Embodiment 1
The vacuum tank of fuel oil air driven pump as shown in Figure 1 and Figure 2, including tank body 1, fuel filler 2, be arranged on inside tank body 1
Central baffle 3, fuel outlet 4, between having between the top and bottom of the central baffle 3 and the top and bottom of tank body 1
Every on the tank body 1 of the fuel filler 2 and the centrally disposed both sides of dividing plate 3 of fuel outlet 4.
Horizontal dotted line in Fig. 1 is the fuel level injected after fuel oil, and fuel level bottom is the fuel oil of injection, Fig. 1
The middle dotted line with arrow represents the direction of fuel flow.In the side sectional view of Fig. 2, it can be seen that fuel filler 2, fuel oil goes out
Mouth 4 fails display back to direction positioned at fuel filler 2.
When using fuel oil air driven pump supply fuel oil, the fuel filler of the high pressure fuel of the pneumatic pump discharge of fuel oil from vacuum tank
After 2 enter tank body 1, it is directly impinging in central baffle 3, so as to reduce the impact to fuel outlet 4.Fuel oil reach center every
After plate 3, enter the side of fuel outlet 4 from the gap of central baffle 3 Yu the bottom of tank body 1, and then voltage stabilizing is flowed out from fuel outlet 4
Tank.When the fuel pressure of fuel oil air driven pump pumping is larger, the fuel pressure in vacuum tank is also larger, the gas on vacuum tank top
Compressed, fuel pressure is gathered way and slow down；When the fuel pressure of fuel oil air driven pump pumping is smaller, the fuel oil in vacuum tank
Pressure is also smaller, and now the gas on vacuum tank top can then expand, and the speed for reducing fuel pressure slows down.So, this practicality
The new effect for just serving stabilization fuel pressure, makes fuel pressure meet the job requirement of engine.
Embodiment 2
The vacuum tank of fuel oil air driven pump as shown in Figure 3, including tank body 1, fuel filler 2, be arranged on inside tank body 1
Centre dividing plate 3, fuel outlet 4, have interval, institute between the top and bottom of the central baffle 3 and the top and bottom of tank body 1
State on the tank body 1 of fuel filler 2 and the centrally disposed both sides of dividing plate 3 of fuel outlet 4, the bottom of the tank body 1 sets oil return opening
5, the fuel filler 2 is connected with the fuel oil air driven pump 6 of input fuel oil, and the oil return opening 5 is connected with fuel oil air driven pump 6.
The utility model can also avoid fuel oil air driven pump in low temperature ring in addition to playing a part of stabilization fuel pressure
The problem freeze when being worked under border, being stopped.As shown in figure 3, when fuel oil is supplied using fuel oil air driven pump 6, voltage stabilizing
The oil return opening 5 of the bottom of tank 1 is opened, and is connected with fuel oil air driven pump 6, so can between fuel oil air driven pump and vacuum tank shape
Into the peripheral passage of fuel oil, ensure that fuel oil air driven pump 6, with the speed pumping fuel of stabilization, prevents air driven pump from freezing, stopping
Work.
Embodiment 3
The vacuum tank of fuel oil air driven pump as shown in Figure 4 is there is provided pressure gauge on the basis of Fig. 3 at the top of tank body 1
7, can be used in monitoring the internal pressure of vacuum tank.
What embodiment of the present utility model was announced is preferred embodiment, but is not limited thereto, the common skill of this area
Art personnel understand spirit of the present utility model easily according to above-described embodiment, and make different amplifications and change, but as long as not
