Embodiment Construction

[0026] The technical scheme of the present invention is described in further detail below:

[0027] A method for measuring liquid viscosity based on a falling ball, characterized in that it specifically comprises the following steps:

[0028] Step 1, set up a bracket, set two pulleys on both sides of the bracket, connect the ball and the weight source through the lead wire and slide through the two pulleys;

[0029] Step 2, setting a label on the lead;

[0030] Step 3, analyze the movement speed of the label through multiple speed sensors, and then obtain the speed when the ball falls into the liquid to be tested and falls at a constant speed;

[0031] Step 4, calculate the viscosity of the liquid according to the velocity when the ball falls at a constant speed, specifically:

[0032] m 小球 g-F 浮 -F 粘 -m 重量源 g-F 滑轮 = 0;

[0033] Get η=1 / 6πrv(m 小球 g-πr 3 ρg 4 / 3 -m 重量源 g-2m 重量源 gμ 阻 );

[0034] r is the radius of the ball, η is the viscosity of the liquid to be me...

Abstract

The invention discloses a liquid viscosity measurement method based on falling balls. A bracket is arranged; two pulleys are arranged on two sides of the bracket; the balls and a weight source are connected with each other through leads and slide through the two pulleys; a label is arranged on each lead; and the movement speeds of the labels are detected through a plurality of speed sensors to be analyzed, so as to obtain the speeds when the balls fall into a to-be-tested liquid at constant speeds, so that the viscosity of the to-be-tested liquid is accurately calculated through the falling speeds of the balls according to the falling ball stockhaus formula.

Description

technical field [0001] The invention relates to a measurement method, in particular to a liquid viscosity measurement method based on a falling ball, and belongs to the field of measurement control. Background technique [0002] Today's global problem is undoubtedly an energy issue, because there are countless wars caused by energy, and the competition between countries in the future will mainly be energy wars. Therefore, it is very important to study the viscosity of oil. From the viscosity test data, the layer of oil can be judged to distinguish its purity. In this way, the oil content in the test area can be judged to decide whether to mine. In this way, resources can be saved, and manpower and material resources will not be wasted on areas that are not of use value. The quality of commodities in today's society is also an issue worthy of attention. Some drinks and milk powder are mixed with other harmful ingredients, and viscosity is an important indicator for judging t...
