Fig. 1 is a schematic view of the structure of the device of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in figure 1, a device of petroleum product density measurement, including splendid attire container 1, pack into distilled water 2 in splendid attire container 1, placed survey buret 3 in distilled water 2, seted up toper inlet 4 on the top of surveying buret 3, be provided with 0 scale mark 5 on the upper end pipe wall of surveying buret 3, the below of zero scale mark 5 is provided with scale mark 6, survey buret 3's bottom be provided with survey buret 3 integrated into one piece's flourishing liquid storehouse 7, flourishing liquid storehouse 7 is provided with liquid measure mark zone 8 with the bottom junction of surveying buret 3, is connected with weighing storehouse 9 in flourishing liquid storehouse 7's below, and the petroleum product that awaits measuring enters into flourishing liquid storehouse 7 by inlet 4 in, and weighing storehouse 9 ensures that survey buret 3 is vertical in distilled water 2.
The container 1 is made of transparent materials, so that the scale value on the measuring tube 3 can be observed conveniently.
The measuring tube 3 and the liquid containing bin 7 are made of transparent PE materials.
The balance weight material in the balance weight bin 9 is pure iron.
The liquid containing bin is 7-position ellipsoidal.
The diameter of the container 1 is three to five times the diameter of the measuring tube 3.
Because the utility model discloses a purpose is the liquid that measures this kind of density of alkane petroleum product and be less than water, and the weight of the petroleum product of same volume is less than the pure water moreover, consequently, after loading the petroleum liquid of being surveyed, survey buret (3), inlet (4), 0 scale mark (5), scale mark layer (6), flourishing liquid storehouse (7) and weigh the hydrometer of storehouse (9) constitution and will float the appropriate amount. Therefore, the density scale zero mark of the densitometer is designed to be arranged at the uppermost part of the scale area. The zero point scale is the position of a waterline determined when pure water with a certain volume is loaded;
by loading water with equal volume and the liquid to be measured into the liquid containing bin 7, the waterline is positioned on the measuring pipe 3 when the two comparison liquids are loaded in the comparison liquid containing bin 7, so that the density of the liquid to be measured is measured.
The measuring tube 3 and the liquid containing bin 7 have fixed volumes according to the formula:
ρ＝m/v (1)
the draft is related to the internal liquid density.
The measuring tube 3 and the liquid containing bin 7 are made of plastic, and in order to keep the measuring tube 3 and the liquid containing bin 7 in a stable vertical posture in water, PE (polyethylene) which is a material with low density and good transparency is adopted. After the measuring tube 3 and the liquid containing bin 7 contain any liquid, the liquid containing bin 7 is always submerged below the water surface, so that when the density of various liquids is measured, the submerged depth of the liquid containing bin 7 in the water depends on the parameter reading of the measuring tube 3.
Assuming that the diameter of the measuring pipe 3 is d and the submergence depth of the measuring pipe 3 in water is h, then as h changes, the water displacement volume of the measuring pipe 3 will be:
in conjunction with equation (1), there is:
at the same time, in the formula M1For measuring the dead weight of the tube 3 and the liquid storage bin 7, MxFor the weight of the liquid measured, then:
Mwater (W)＝M1+Mx (4)
Assuming that the ratio between the dead weight of the measuring tube 3 and the liquid storage tank 7 and the weight of the measured liquid is n:
Mwater (W)＝(n+1)Mx＝ρWater (W)·vWater (W) (5)
It can be seen from formula (5) that when the liquid storage 7 contains a liquid to be measured, the value of the ratio n will influence the volume of the drained water by multiple times, and further influence the floating and sinking amplitude of the hydrometer.
From the above derivation: the density of the material used in the hydrometer is an important factor for determining the size of the hydrometer.
In order to facilitate the use and reduce the use cost of a laboratory, the measuring tube 3, the liquid containing bin 7 and the weighing bin 9 are made of plastic materials and can be designed into a disposable type;
according to the assumption of integral modeling, the opening of the measuring tube 3 is a small opening similar to a thin tube, and the bottom liquid containing bin 7 is thin in wall and can be extruded, so that the function of a densimeter suction tube is given, the sampling is convenient, and meanwhile, the design of the small opening is beneficial to keeping volatile components in the measured liquid.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
