The course of work is as follows: at engine 10 during in running status, fuel oil arrives service tank 11 through electric oil pump 1, the second retaining valve 12, liquid flow sensor 3, engine oil inlet pipe 5 extracts fuel oil from service tank 11,6 oil returns of engine oil return pipe are to service tank 11, in the time that oil level arrives high liquid level sensor 8, electric oil pump 1 stops pump oil, and in the time that oil level arrives low liquid level sensor 9, electric oil pump 1 starts pump oil.Time and mileage signal are recorded all the time.The front pump oil of each electric oil pump 1 is with next time between pump oil, the measured value of liquid flow sensor 3, and the fuel consume of correspondence in the time that the mileage being travelled during this period exactly consumes, fuel consumption is shown, and is stored.
Matching program software, realize full intellectualized, without manual operation.
The principle of measuring fuel consume is: this device is used in motor car engine, when engine is during in running status, engine is pumped from service tank, engine oil return is got back to service tank, the state of electric oil pump is saved, in the time that the low liquid level sensor of service tank sends low oil level signal to intelligent control module, intelligent control module is switched on to electric oil pump by oil pump driver module, electric oil pump work, to service tank supply fuel oil, the fuel oil volume of supply detects by liquid oils quantity sensor, the result store of measuring is in intelligent control module, in the time that pasta arrives the highest liquid level, the highest liquid level is sent signal to intelligent control module, intelligent control module makes electric oil pump power-off, electric oil pump quits work, the first retaining valve plays and prevents fuel flow returns, prevent the effect that fluid flow measures repeatedly.Service tank is measured more difficult problem with solving oil return, and will enter, oil return is used as an entirety and considers.During measuring, odometer sensor transmits mileage signal to intelligent control module, clock module is to intelligent control module transmitting time signal, go round and begin again, between each minimum liquid level and the highest liquid level, the fuel consumption in can measuring during this period of time, hundred kilometers of fuel consumption, fuel consumption per hour, in the time that engine stop moves, the fuel consume total amount can measure its last operation time.
This device is used on stationary engine, and as diesel generator set, when diesel unit, principle is the same, just there is no the function of mileage signal and calculating mileage.
If the volume in service tank 11 between high liquid level sensor 8 and low liquid level sensor 9 is certain, can remove liquid flow sensor 3, the fuel consumption of engine 10 still can be measured, and consumption is that the oil pumping number of times of electric oil pump 1 is multiplied by the volume between high liquid level sensor 8 and low liquid level sensor 9 in service tank 11.
When several stationary engines share a service tank 11, use a liquid flow sensor 3, the fuel consume of so several engines 10 still can calculate, and the result of calculating is several engine fuel consumption quantity sums.
