Soil-engaging part lubrication drag-reduction performance test bench

Abstract

The invention discloses a soil-engaging part lubrication drag-reduction performance test bench. The bench is composed of a supporting frame, a soil tank, a motion control device, a data acquisition device and a lubrication adjusting device; the soil tank is fixedly arranged on the supporting frame; the motion control device is fixedly arranged above the soil tank; the lubrication adjusting deviceis fixedly arranged at the upper left side of the soil tank; and the data acquisition device is fixedly arranged at the upper end of the soil tank. When the soil-engaging part lubrication drag-reduction performance test bench works, the rotation speed and direction of a servo motor are set; the drag-reduction effect of a soil-engaging part under a lubrication condition is evaluated through measuring and comparing the quality of soil adhered to the soil-engaging part under the lubrication condition and the quality of soil adhered to the soil-engaging part with no lubrication provided, and therefore, a drag-reduction effect evaluation method is simple and direct. The soil-engaging part lubrication drag-reduction performance test bench of the invention has the advantages of simple structure,operational easiness, accurate test and high working efficiency. With the soil-engaging part lubrication drag-reduction performance test bench adopted, the drag-reduction effect of the surface of thesoil-engaging part of a machine can be realized.

Description

technical field [0001] The invention relates to the field of testing and testing, in particular to a test bench for testing the lubrication and drag reduction performance of parts in contact with soil. Background technique [0002] The adhesion and resistance of the soil to the surface of the subsoiler shovel, wheels, crawler tracks and working parts seriously affect the working efficiency, service life and working quality of the machine tool, and increase the energy consumption. For the adhesion problem of soil-contacting mechanical parts, researchers have proposed many solutions from different angles, and carried out application tests on various soil-contacting parts of ground machinery. Among them, the liquid filling method (water, gas, oil, and a certain concentration of polymer solution, etc.) has a good and excellent effect of reducing viscosity and drag, but due to the passive output of liquid or gas, the efficiency is not high to some extent. , Excessive demand for ...

Problems solved by technology

Among them, the liquid filling method (water, gas, oil, and a certain concentration of polymer solution, etc.) has a good and excellent effect of reducing viscosity and drag, but due to the passive output of liquid or gas, the efficiency is not high to some extent. , excessive demand for lubricating medium, etc., therefore, it is very important to test the relationship between the flow rate, flow rate and adhesion of the output liquid

At present, there is no special measuring device to complete the test of adhesion force under lubricating conditions. There are limitations in all aspects. In order to measure the adhesion resistance of the lubricated soil contact sample when it advances in the soil, it is required that the test device can accurately control the flow rate, flow rate, forward speed and payload of the lubricating fluid, and can quickly and accurately measure the test. Adhesive resistance during sample advance
