Embodiment
Below in conjunction with accompanying drawing, principle of work of the present utility model and process are described further.
Be illustrated in figure 2 as the interface schema of the utility model fuel consumption meter, A～D as mentioned above, interface E is a fuel oil emptying interface, and each interface is described in detail as follows: (1) fuel delivery master oil-feed interface A, must install a safety valve 19 and filtrator between main supply tank and the mass rate fuel consumption meter; (2) engine oil-in B, when mass rate fuel consumption meter and fuel oil thermostat use jointly, this oil-in links to each other with main fuel feeding interface on the fuel oil thermostat, if service property (quality) flow fuel consumption meter separately, then this interface directly links to each other with the engine oil-in; (3) engine oil return interface C, when mass rate fuel consumption meter and fuel oil thermostat use jointly, this interface links to each other with exhaust port on the fuel oil thermostat, if no exhaust port is then directly closed, if independent service property (quality) flow fuel consumption meter, then this interface directly links to each other with the engine oil return opening; (4) fuel overflow exhaust port D, when fuel consumption meter breaks down, fuel oil might overflow from the oil-feed fumer, so a liquid collecting jar need be installed near fuel consumption meter, link to each other with the liquid collecting jar or directly links to each other with the oil extraction pipeline of testboard bay by this interface; (5) fuel oil emptying interface E, interface are provided with one and manually control exhaust-valve 20, if an oil extraction pipeline is being arranged with installing and using, connect this interface and oil extraction pipeline.
Be illustrated in figure 3 as the structural representation of the utility model mass rate formula fuel consume measuring instrument, A～D represents four import and export of fuel oil among the figure, is specially A: fuel delivery; B: engine oil-feed; C: engine oil return; D: fuel overflow/exhaust.This fuel consumption indicator comprises oil-feed exhaust apparatus and oil-feed measurement mechanism, the oil-feed exhaust apparatus comprises the oil-feed fumer, oil-feed fumer inside is provided with filter screen 8, overflow exhausr port and calibrating installation 9, inflow point is provided with oil-feed pneumatic control valve 1, the filter screen top is provided with the spacing float switch 2 with oil-feed pneumatic control valve 1 control linkage, and described oil-feed fumer top is higher than spacing float switch place and is provided with overflow float switch 3 and the overflow manually operated control valve 5 that links to each other with its control; The oil-feed measurement mechanism comprises fuel pump 10 and the mass flowmeter 12 that links to each other with the engine oil-in, be provided with successively between described fuel pump and the mass flowmeter by bypass line respectively with other accumulator 17 and the pressure transducer 18 that links to each other that connect of oil feed line, be provided with shut-off valve 13 between mass flowmeter and the engine oil-in, also be respectively equipped with internal pressure regulator 11 and outlet oil pressure regulator 14 before and after the mass flowmeter, the oil-in of engine also unloads stream valve 15 by a bypass and forms exhaust gas inside pipeline 7 with oil-feed fumer diconnected, and the oil return opening of engine links to each other with the engine oil-in with the oil-feed fumer respectively by three-way diverter valve 16 and forms outside gas exhaust piping 6.
In addition, by electric controling mode, when fuel oil in the oil-feed fumer too much surpassed spacing float switch 2, spacing float switch just cut out coupled fuel oil oil-feed pneumatic control valve 1, and the liquid level of fuel oil in fuel tank always remained on the corresponding liquid level.Fuel oil itself is expanded or the formation bubble in case the rising of fuel pipe temperature occurs, even spacing float switch 2 has made fuel oil oil-feed operation valve cut out, the liquid level of fuel oil still might rise to the overflow liquid level in the fuel tank, fuel oil might overflow from fuel tank, in case generation fuel overflow, the overflow float switch 3 of fuel tank is reported to the police, and at this moment discharges an amount of fuel oil by the liquid collecting jar that links to each other with the overflow exhaust port, continues to use after fixing a breakdown according to actual conditions again.
When the timing signal that returns to zero, earlier mass flowmeter is drained gas, be full of and treat to close the next oil supply of shut-off valve 12 cut-outs again after the fluid measured, under condition, return to zero near working temperature.When changing significantly, change of installation aspect or temperature need readjust.
The accumulator of this fuel consumption meter is except the effect of eliminating pulse and vibration, and the back that can also quit work at the main power source of oil circuit provides of short duration fuel delivery as auxiliary power source for system.The adjusting of fuel pump obtains by two different working modes: (1) pump delivery intermittently, keep system pressure by accumulator; (2) regulate (big flow) continuously, the state of pump is continuous running.When the required fuel flow of engine was not too big, fuel pump was in step duty by the signal controlling of pressure transducer, thereby improves greatly the serviceable life of fuel pump.
The course of work of mass rate formula fuel consume measuring instrument of the present utility model is as follows: under normal circumstances, the oil of main in-line enters the oil-feed fumer under the control of oil-feed pneumatic control valve, with the bubble separation in the fuel oil, gas is discharged from the overflow exhausr port by filter screen; Fuel oil enters the oil-feed measurement mechanism, and fuel pump realizes that under the control of accumulator and pressure transducer pressure regulates, and after entering mass flowmeter measure under steady state (SS), the adjusting through the outlet oil pressure regulator enters engine again.In addition, if fuel consumption meter inside is owing to reasons such as temperature variation have produced bubble, or fuel consumption meter is connected with fuel oil constant temperature or engine when using, produced bubble in fuel oil constant temperature pipeline and the engine fuel pipeline, can get back to oil-feed fumer circulating exhaust by exhaust gas inside pipeline 7 and outside gas exhaust piping 6, guarantee the measuring accuracy and the job stability of system.
The circulation of native system oil has Wu Tiaolu:
(1) come oil successively by entering engine behind oil-feed fumer, fuel pump 10, accumulator 17, pressure transducer 18, internal pressure regulator 11, mass flowmeter 12, the outlet oil pressure regulator 14;
(2) come oil by behind the oil-feed fumer internally gas exhaust piping 7 directly enter engine;
