Portable rotation tester

Abstract

A portable rotation tester disclosed by the present invention comprises a supporting rod, a mounting frame and a containing box, a mounting plate is mounted at the top end of the supporting rod, a fixing frame is mounted at the bottom of the mounting plate through bolts, the mounting frame is mounted at the top of the mounting plate, and the containing box is movably mounted on the inner side of the top of the mounting frame. A fixing shaft is movably installed on the outer side of the containing box, a fixing piece is installed on the outer side of the fixing shaft, the bottom end of the fixing piece is installed on the top of the installation frame, and a pneumatic cylinder is installed on the top of the containing box. The cleaning device is installed at the top of the containing box, so that magnetic fluid residues on the inner wall of the containing box can be removed, the inner wall is cleaner, and the situation that the rotating speed of magnetic fluid is affected by a large amount of magnetic fluid residues is avoided.

Description

technical field [0001] The invention relates to the technical field of testers, in particular to a portable rotation tester. Background technique [0002] The rotation tester is used to test the rotation speed of the magnetic fluid. The drive motor in the rotation tester drives the holding box to rotate, so that the magnetic fluid inside the holding box is rotated to detect the flow rate. The magnetic fluid is also called magnetic liquid. , ferrofluid or ferrofluid, is a functional material with fluidity, which contains solid materials. [0003] The deficiencies of the existing rotation testers are: [0004] 1. The traditional rotation tester drives the holding box to rotate through the motor, and the holding box will shake when rotating, which will lead to the inaccuracy of the internal magnetic fluid test and easy to cause errors. [0005] 2. The traditional cleaning device for the inner wall of the holding box of the rotary tester. After a long time of use, a large amou...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional rotation tester drives the storage box to rotate through the motor, and the storage box will shake when it rotates, which will lead to inaccurate internal magnetic fluid testing and easily cause errors

[0005] 2. The cleaning device for the inner wall of the holding box of the traditional rotating tester. After a long time of use, a large amount of magnetic fluid residue will remain on the inner wall of the holding box, which will affect the test of the magnetic fluid.
