Wet density testing device

Abstract

The invention discloses a wet density testing device comprising a water tank, a scale hanging frame, an electronic scale, a weighing disc, an irregular sample box, a circular sample holder, a resistance heater, a water injecting component and a water drainage component, the two feet of the scale hanging frame are respectively fixed on the top of two opposite side surfaces of the water tank, the scale hanging frame is provided with a connecting ring in relative sliding movement with the scale hanging frame, the connecting ring is connected through a connecting rope with the top of the electronic scale, a hook and the weighing disc are connected below the electronic scale by a connecting rope, the irregular sample box and the circular sample holder are respectively arranged at the positions, near the top, of the inner side wall of the water tank, the resistance heater is arranged at the position, near the bottom, of the inner side wall of the water tank, the water injecting component and the water drainage component are respectively arranged at the positions, near the top and near the bottom, of the outer side wall of the water tank, and are communicated with the interior of the water tank. The wet density testing device can rapidly and accurately measure the wet density of a circular sample or an irregular block sample.

Description

technical field [0001] The invention belongs to the field of solid density testing devices, in particular to a wet density testing device. Background technique [0002] In the process of modern product production, processing and research and development of new materials, density is often a key physical parameter that needs to be measured frequently, and it has important reference value for evaluating and improving product or material performance. For various solid samples with a density greater than water, the traditional density testing device mostly uses the principle of the Archimedes drainage method to calculate the wet density of the sample (the sample volume does not include open pores, but includes closed pores): when testing, first place the sample Obtain the weight of the sample in water on the tray submerged in water, and then according to the formula (W 0 is the weight of the sample in air, W 1 is the weight of the sample in water, ρ 1 is the density of water...
