Detailed Description

The invention is described in further detail below with reference to the figures and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and are not intended to limit the scope of the invention.

As shown in fig. 1, the device for measuring the consumption of the diesel engine oil comprises a container 12, a magnetostrictive liquid level meter sensor 1, a continuously running oil-pressing pump pipeline 10 and an oil-returning pump pipeline 9; the top of the container 12 is provided with an oil filling hole 2; the input end of the pressure oil pump pipeline 10 is connected with the diesel engine 11, and the output end of the pressure oil pump pipeline is connected with the top of the container 12; the input end of the oil return pump pipeline 9 is connected with a container 12, and the output end of the oil return pump pipeline is connected with a diesel engine 11; wherein, the magnetostrictive liquid level meter sensor 1 is arranged at the top end of the container 12 and is used for measuring the height of the engine oil in the container 12; wherein the cross-section of the upper part of the container 12 is smaller than the cross-section of the bottom part.

The oil pump in the hydraulic pump line 10 draws oil from the oil pan of the diesel engine 11 into the reservoir 12. In order to facilitate observation of the oil level when adding the oil, the liquid level meter 8 is arranged on the side surface of the container 12, the bottom of the container 12 is provided with an oil drain valve pipeline 7 for facilitating oil drainage, the upper part of the container 12 is provided with an overflow pipe 3 and a stop valve 4, and the lower parts of the overflow pipe 3 and the stop valve 4 are provided with a recovered oil container 5 and a waterproof printing electronic platform scale 6 for facilitating weighing of the oil flowing out of the container 12; the magnetostrictive liquid level meter sensor 1 is arranged at the top of the container 12, so that the change of oil consumption of engine oil can be conveniently measured, and an oil filling hole 2 is arranged so that the engine oil can be conveniently added; meanwhile, the oil filling hole 2 also has the function of a vent; the engine oil in the container 12 is delivered to the diesel engine 11 by the hydraulic oil pump in the hydraulic oil pump pipeline 9, and the engine oil circulation is completed.

As is well known, the conventional engine oil measurement directly measures the change of the engine oil consumption of the oil pan, and the sectional area of the oil pan is large and the sectional area changes inconsistently, so that the time required for starting up the diesel engine is long when the engine oil is measured, a large amount of resources such as fuel oil, lubricating oil, water and electricity are wasted, and the pollution to the environment is increased. Meanwhile, the traditional method needs to read the number of oil drops per minute, the waiting time is long due to high viscosity of the engine oil, the viscosity of the engine oil is increased due to the temperature reduction of the engine oil after the diesel engine is stopped, and the whole measuring process consumes long time.

Even if an authorization notice number is used: the technical scheme in CN 103277168A "engine and engine oil consumption detection device and method thereof" also cannot be applied to the situation that the section of the diesel engine is complicated and variable.

To illustrate the different cross-sections of diesel engines, the following specific examples are provided for illustration.

Specific example I: the diesel engine oil consumption measuring device is a method for measuring the oil consumption under the condition of the liquid level with the equal section.

Firstly, adding engine oil with equal mass into a container 12 in a plurality of times, and measuring liquid level change data through a magnetostrictive liquid level meter sensor 1;

then, according to the ratio of the total amount of the added engine oil to the corresponding liquid level change data, calculating a coefficient;

and finally, after the engine oil measurement is finished, the oil consumption is obtained by dividing the liquid level data of the magnetostrictive liquid level meter sensor 1 by the coefficient.

Such as: before the measurement, the magnetostrictive level gauge sensor 1 was zeroed, and the average coefficient was determined to be 5 by 5 refuelings in total, and after the measurement was completed, the oil consumption was 10/5-2 in the data 10 recorded by the magnetostrictive level gauge sensor 1.

Specific example II: the diesel engine oil consumption measuring device is a measuring method for the oil consumption under the condition of unequal cross-section liquid levels.

Before measuring the oil consumption, the magnetostrictive level gauge sensor 1 data is recorded, after the end of the measurement, the oil is added to the batch container 12 and the mass of the added oil is recorded until the magnetostrictive level gauge sensor 1 records the data. The sum of the masses of the engine oils added at this time is the amount of the engine oil consumed.

Such as: before measuring the oil consumption, recording the magnetostrictive liquid level meter sensor 1 to display 5, after the measurement is finished, adding the oil for 6 times, and recording the amount of the added oil each time until the magnetostrictive liquid level meter sensor 1 displays data 5, the total amount of the added oil is 2, and then the oil consumption is 2.

Specific example III: in the actual production process, in order to save cost, the magnetostrictive liquid level meter sensor 1 can not be arranged in the diesel engine oil consumption measuring device. In this case, the measurement method for the diesel engine oil consumption measurement is:

firstly, opening a stop valve 4, enabling the engine oil in a container 12 to flow into a recovered engine oil container 5 through an overflow pipe 3, and measuring the quality of the engine oil in the recovered engine oil container 5 through a waterproof printing electronic platform scale 6 to obtain initial data;

then, the stop valve 4 is closed, and the engine oil in the recovered engine oil container 5 is poured into the container 12 again;

after the diesel engine 11 works for a period of time, the stop valve 4 is opened again, the engine oil in the container 12 flows into the recovered engine oil container 5 through the overflow pipe 3, the quality of the engine oil in the recovered engine oil container 5 is measured through the waterproof printing electronic platform scale 6, and the data after operation are obtained;

and finally, performing difference on the operated data and the initial data to obtain the engine oil consumption.

Such as: before the measurement, the engine oil amount is measured to be 5, and after the diesel engine 11 is operated for a certain period of time, the engine oil amount is measured to be 3, and the difference between the two is 5-3-2, which is the engine oil consumption.

It is to be understood that:

the shape of the container 12 is shown in fig. 1, and for accurate measurement, the magnetostrictive level gauge sensor 1 is located at the upper part with a smaller cross section, and the change in the mass of the oil is more obvious corresponding to the rise and fall of the liquid level.

The magnetostrictive level gauge sensor 1 described herein may be a smart digital display magnetostrictive level gauge sensor.

The hydraulic pump line 10 and the scavenge pump line 9 described herein are used to circulate oil from a reservoir 12 to the engine oil in the diesel engine 11.

The container 12 described herein is vented to the environment through the filler opening 2, and is otherwise sealed.

All directional descriptions referred to herein shall control fig. 1.

The above description is only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily change or replace the technical scope of the present invention. Therefore, the protection scope of the present invention is subject to the protection scope of the claims.
