Abstract

The utility model discloses a liquid densimeter which comprises an electronic balance, a liquid groove, a metal body, a lifting platform, and a hook; the liquid groove is disposed on the electronic balance; the metal body is hung on the lifting platform through the hook, and is immersed in the liquid groove; the metal body is a rotator with a smooth surface; the outer surface of the metal body is made of a corrosion resistant material; a lead core is disposed inside the metal body. The beneficial effects of the utility model are that: firstly, liquid density can be measured rapidly and accurately; secondly, the metal body is a rotator with a smooth surface, which is convenient for cleaning, can effectively reduce the using amount of organic solvents, and facilitates environmental protection.

Description

A kind of liquidensitometer

Technical field

The utility model relates to a kind of densitometer, relates in particular to a kind of measurement mechanism of fluid density.

Background technology

At present; The method that mensuration adopted to coating density is " the mensuration pycnometer method of GB/T 6750-2007 paint and varnish density ", and the measuring principle of this method is to fill sample with pycnometer, and the quality of sample and known pycnometer volumescope are calculated the density of test product in the pycnometer; Therefore; All to clean up before not only each the measurement with the organic solvent coating that last time in the pycnometer is remaining, and the coating that overflows outside in measuring process, also will noting at any time clearing up, every like this measurement once not only requires a great deal of time and is used for cleaning; Also need use a large amount of organic solvents, contaminated environment.

Summary of the invention

The utility model problem to be solved is: a kind of liquidensitometer is provided, can quick and precisely measures density of liquid, and can effectively reduce the use amount of organic solvent, and avoid because of cleaning trouble caused.

For overcoming the above problems, the technical scheme that the utility model adopted is:

A kind of liquidensitometer comprises electronic balance, liquid tank, metal solid, lifting table, hook, and said liquid tank is positioned on the electronic balance, and said metal solid hangs on the lifting table through hook, and is immersed in the liquid tank.

Said metal solid is ganoid rotary body; The outside surface of said metal solid is processed by the corrosion resistance material; The outside surface of metal solid is processed by Nitinol; The inside of metal solid has lead for retractable pencil.

Because the inside of metal solid has lead for retractable pencil, has increased the quality of metal solid, so metal solid can be immersed in the bigger sample of density and not floating.In measuring process, to placing liquid tank on the electronic balance to add the testing liquid sample of an amount of volume, regulate the height of lifting table, be immersed in the testing sample and make not contact liq trench bottom of metal solid hanging over metal solid on the lifting table.The reading of electronic balance is poor before and after the record submergence, and this numerical value is the mass M that metal solid arranges fluid sample, and based on Archimedes principle, the density of fluid sample equals the volume V of M divided by metal solid.

The beneficial effect of the utility model is: one of which, can quick and precisely measure density of liquid; Two, metal solid is ganoid rotary body, so convenience for washing, can effectively reduce the use amount of organic solvent, useful environmental protection.

Embodiment

Below in conjunction with accompanying drawing and embodiment the technical scheme of the utility model is further introduced.

As shown in Figure 1: a kind of liquidensitometer; Comprise electronic balance 1, liquid tank 2, metal solid 3, lifting table 4, hook 5; Said liquid tank 2 is positioned on the electronic balance 1, and said metal solid 3 hangs on the lifting table 4 through linking up with 5, and is immersed in the liquid tank 2.

As shown in Figure 4: said metal solid 3 is ganoid rotary bodies; The outside surface of metal solid 3 is processed by Nitinol; The inside of metal solid 3 has lead for retractable pencil (not shown).

Shown in Fig. 2-3: at first add abundant testing sample in the liquid tank on electronic balance 12; And with electronic balance 1 zero clearing; Then metal solid 3 is suspended on the other lifting table 4 of electronic balance 1, and the height through adjustment lifting table 4, guarantees that metal solid 3 can be by the fluid sample submergence and do not contact with the bottom of liquid tank 2; The current quality of electronic balance 1 demonstration this moment; Be the mass M of the sample that arranges, the ratio of mass M and the volume V of metal solid 3 can obtain measured density of liquid M/V then.

The utility model is not limited to above-mentioned embodiment; Announcement and guidance according to above-mentioned instructions; The utility model those skilled in the art also can carry out suitable change and modification to above-mentioned embodiment, and its change also should fall into the protection domain of the claim of the utility model.In addition, although used some specific terms in this instructions, these terms are explanation for ease just, the utility model is not constituted any restriction.
