The invention discloses a device for testing the flow velocity of a liquid drop under gravity on material surfaces at different temperatures. An object to be tested is fixed to a heating plate and heated, and the temperature value of the object to be tested is tested by a temperature testing probe and transmitted to a temperature collecting heater; a testing table transverse movement screw is rocked so that a testing table telescopic support can move transversely along a transverse movement guide rail to adjust the position of a testing table and then adjust the position of the object to be tested; the inclination angle of a U-shaped rotating guide rail can be adjusted by rocking a rotating screw, and then the inclination angle of the object to be tested can be adjusted; the liquid drop dropping from a microsyringe falls onto the object to be tested and is located within a tracing signal receiving range, the liquid drop slides downwards under gravity after falling onto the object to be tested, and the flow velocity of the liquid drop is tested by a liquid drop flow velocity receiver 3 and transmitted to a computer through a transmission line. By means of the device, the flow velocity of the low-flow-velocity liquid drop on the surfaces of various materials to be tested at different temperatures and different inclination angles can be tested.
Description
technical field [0001] The invention relates to a device for testing the flow velocity of liquid droplets on the surface of materials with different temperatures under their own weight. The invention is used for the measurement of the rolling angle and the calculation of the flow velocity of the liquid with low flow velocity and high viscosity at different heating temperatures, and at the same time can observe the movement of the liquid droplet on the surface. Background technique [0002] At present, there are few methods for measuring the flow rate of droplets or liquids at low flow rates or relying on their own gravity on the surface temperature of the material to be tested. Testing the flow velocity of the surface to be tested at high flow rates, such as water tunnel experiments, is costly and only applicable to high flow rates, and the test of liquid flow velocity at different temperatures on the surface to be tested is limited. The accuracy of water tunnel experiments...
