Background technique
During the engine chamber test, traditional fuel delivery with regulate be by be installed in the fuel pipe manual pin type oil-feed modulating valve and manually the aperture of pin type oil return regulating valve regulate the flow of fuel oil, and these manually-operated gates all are installed on the operating table, at work, oil pump all turns round under rated speed, and most of fuel oil is by the oil return regulating valve step-down, enters return line, after the cooler cooling, come back to the oil pump import, recycle.So just there is following defective:
1, delivery line is long, and jointing is many, and fuel oil is often revealed, and has potential safety hazard, safeguards inconvenience;
2, governing speed is slow, and the adjusting validity is poor;
3, in igniting process, can't realize quantitative fuel feeding, overheating problem often occur;
4, there is not automatic protection functions;
5, oil pump all turns round under rated speed, and energy consumption is big.
Summary of the invention
The purpose of this utility model be to provide one the cover can be to the device of the quantitative fuel feeding of engine chamber, to solve the existing defective of traditional oil supplying device.
The utility model is connected to form by variable-frequency motor, fuel pump, industrial control computer, frequency variator, and its described fuel pump rear end is connected with spherical solenoid directional control valve, turbine flowmeter, one-way valve, testpieces by oil pipe successively; Be provided with rotating coder, rotary flywheel, magnetic clutch on the coupling shaft between described variable-frequency motor and the fuel pump successively.
For further realizing above purpose being equipped with buffer between described fuel pump and the spherical solenoid directional control valve and before the fuel pump oil-feed; Spherical solenoid directional control valve one end is an oil outlet end, and the other end is oil revolving end and is connected with oil storage tank by return tube; Described fuel pump is a unsteady flow amount positive displacement fuel pump.
The advantage of the oil supplying device that the utility model is more traditional is: simple and reliable for structure, easy to operate.Be provided with buffer between fuel pump and nozzle He before the fuel pump oil-feed, fuel flow is regulated steadily.The fuel pump rear end is provided with spherical solenoid directional control valve, can be at 0.1 second internal cutting off fuel feeding, and governing speed is fast, wide ranges, the precision height.Have full-automatic regulation, low, the quantitative fuel feeding of power consumption and automatic protection functions.

Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. variable-frequency motor, 2. rotating coder, 3. rotary flywheel, 4. magnetic clutch, 5. fuel pump, 6. oil storage tank, 7. buffer, 8. spherical solenoid directional control valve, 9. turbine flowmeter, 10. one-way valve, 11. testpieces, 12. industrial control computers, 13. frequency variators, 14 return tubes, 15 oil pipes, 16 coupling shafts.
Embodiment
As shown in drawings, the utility model is connected to form by the frequency variator 13 of variable-frequency motor 1, fuel pump 5, industrial control computer 12, band GPI (rotating speed control panel) plate.Fuel pump 5 is a unsteady flow amount positive displacement fuel pump, is connected with spherical solenoid directional control valve 8, turbine flowmeter 9, one-way valve 10, testpieces 11 by oil pipe 15 successively in its back-end.Rotating coder 2, rotary flywheel 3, magnetic clutch 4 are installed on the coupling shaft 16 between variable-frequency motor 1 and the fuel pump 5.Rotating coder 2 one ends are connected with the frequency variator 13 of band GPI (rotating speed control panel) plate, be connected with buffer 7 by oil pipe 15 between fuel pump 5 and the spherical solenoid directional control valve 8, fuel pump 5 front ends also have additional buffer, the fluctuation that effectively reduces nozzle oil spout flow and measure flow.Spherical solenoid directional control valve 8 one ends are oil outlet end, and the other end is oil revolving end and is connected with oil storage tank 6 by return tube 14.The feedback closed loop that the GPI of frequency variator 13 (rotating speed control panel) plate and rotating coder 2 formed and be installed in the fluctuation that rotary flywheel 3 on the coupling shaft 16 can effectively be controlled fuel pump 5 rotating speeds.
Operating process is as follows:
According to testpieces 11 fuel delivery scopes,, determine the fuel delivery of fuel pump 5 revolutions by regulating the swash plate angle of unsteady flow amount positive displacement fuel pump 5.The initialization frequency of frequency variator 13 is set, starts frequency variator 13, it is electric that magnetic clutch 4, spherical solenoid directional control valve 8 are got, and then magnetic clutch 4 is thrown off, and spherical solenoid directional control valve 8 its oil outlet ends are closed, and oil revolving end is opened.Start fuel pump 5, magnetic clutch 4 dead electricity adhesives, fuel pump 5 entrys into service, fuel pump 5 is by given rotating speed smooth operation, and fuel oil returns fuel pump 5 by the oil revolving end of spherical solenoid directional control valve 8.
After experimental piece 11 igniting, spherical solenoid directional control valve 8 dead electricity, its oil outlet end is opened, oil revolving end is closed, fuel oil with given flow to testpieces 11 fuel feeding.Regulate the output frequency of frequency variator 13 again, can change fuel supply flow rate.
If urgency, it is electric that magnetic clutch 4, spherical solenoid directional control valve 8 are got, can be at 0.1 second internal cutting off fuel feeding.
The utility model can also can alternately be realized by manually or automatically realizing.
In controlling automatically, measure the actual fuel flow that flows to testpieces 11 by turbine flowmeter 9, industrial control computer 12 reads this actual flow value and carries out PID (proportion integration differentiation adjusting) computing with quantitative values, draw output frequency, and the output frequency of change frequency variator 13 can be realized to engine chamber testpieces 11 quantitative fuel feeding.
