Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, the water column height weighing scale comprises a base 1, wherein a cylinder 2 is installed on the base 1, water is contained in the cylinder 2, a floating piston 3 floats on the water surface, the side surface of the floating piston 3 is matched with the inner surface of the cylinder 2, and a weighing object 4 is placed on the floating piston 3;
2 side trompils of barrel and communicate with 5 bottoms of transparent pressure measurement pipe, and 5 upper portion sides of transparent pressure measurement pipe are equipped with bleeder vent 6, are connected with scale 8 through scale fixing clip 7 on the transparent pressure measurement pipe 5, and scale 8 is fixed along 5 vertical directions of transparent pressure measurement pipe, and the scale of the 5 liquid level heights of transparent pressure measurement pipe of reaction on the scale 8, the scale line of the lower department of scale is zero scale mark 9.
The side surface of the floating piston 3 and the inner surface of the cylinder body 2 are both cylindrical and concentric, and the two are tightly attached without water leakage.
The scale 8 can move up and down along the vertical direction of the transparent pressure measuring circular tube 5, when the floating piston 3 is not provided with the weighing object 4, the zero scale mark 9 is aligned with the liquid level of the transparent pressure measuring circular tube 5, and then the scale 8 is fixed on the transparent pressure measuring tube 5 by the scale fixing clamp 7; the weight of the weighed object 4 is reflected by the height h from the liquid level height in the transparent pressure measuring circular tube 5 to the zero scale mark 9; when the water column height weighing scale weighs the same weight of the weighed object 4, the liquid level height h is inversely proportional to the bottom area a of the floating piston 3.
The working principle of the invention is as follows:
referring to fig. 1, in a communicating vessel formed by a cylinder 2 and a transparent pressure measuring circular tube 5, the pressure intensity at each position on the horizontal plane of the bottom surface of a floating piston 3 is equal, and the weight of the floating piston 3 is reflected by the height between the horizontal plane of the bottom surface of the floating piston and a zero scale mark 9 of the transparent pressure measuring circular tube 5; the weight of the weighing object 4 placed on the floating piston 3 is reflected by the height h from the liquid level in the transparent piezometer tube 5 to the zero scale mark 9, and is expressed by formula
m＝ρAh
Wherein m-weigh the mass of the item 4; ρ -density of water; a-piston area; h-distance between the liquid level in the transparent piezometer tube 5 and the zero scale mark 9.
