Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
A suspension type liquid density measuring device as shown in fig. 1-3, which comprises a spherical shell 1, a stepping motor 2, a plunger 3 and a control display.
The spherical shell 1 comprises an upper hemisphere and a lower hemisphere, and the upper hemisphere is detachably connected with the lower hemisphere in a sealing manner. The assembling surface between the upper hemisphere and the lower hemisphere is provided with four mutually interference fit pin columns and pin holes at even intervals along the circumferential direction, and the upper hemisphere and the lower hemisphere are inserted in the pin holes to be mutually connected through the pin columns in an interference embedded mode. The assembly surface between the upper hemisphere and the lower hemisphere is also provided with a sealing groove and a sealing lug which are embedded and matched to form a leakage-stopping structure. Spherical shell 1 sets up to detachable hemisphere structure and is favorable to maintaining and changing the components and parts in the casing, if can conveniently change step motor 2's power.
The lateral wall of plunger 3 is equipped with the length scale, and the 0 scale value of length scale is located the bottom of plunger 3, and the numerical value of length scale increases from bottom to top, stretches out the length that spherical shell 1 can calculate plunger 3 through plunger 3 and stretches out the volume, also is plunger 3's displacement volume. Also, step motor 2 is equipped with the revolution detector, and the revolution detector is connected with the control display through wireless mode (like the bluetooth), through the revolution that detects step motor 2 drive plunger 3 and stretch out to the calculation obtains the length of stretching out and the volume of plunger 3, thereby obtains the displacement volume of plunger 3 promptly.
The principle of the suspension type liquid density measuring device for detecting the liquid density is as follows: when the device is wholly suspended in a liquid, MHeavy load＝FFloating bodyAccording to mg ═ ρ gV, where m is the mass of the device, a known parameter; rho is the density of the liquid to be measured; v is the displacement volume of the device, equal to the sum of the displacement volume of the plunger 3 and the displacement volume of the spherical shell 3. When the device is applied to the density detection of multilayer liquid, through adjusting the displacement volume, the lift that can realize the device reaches the suspension equilibrium state in the liquid of different layers to can calculate according to rho and obtain the density of this layer of liquid for m/V.
