Impact high pressure viscometer and method of testing

Abstract

This invention discloses an impact-type high-pressure viscometer and its testing method. The impact-type high-pressure viscometer includes: a base plate; an optical container suitable for containing the liquid to be tested; an optical detection and recording device suitable for recording the changes in interference fringes of the liquid to be tested; two guide rods; a connecting frame, with its two ends respectively movably mounted on the two guide rods, and impact elastic elements suitable for driving the connecting frame downward; an impact element mounted on the connecting frame and suitable for impacting the liquid to be tested; a vertical plate; and an impact release device, the height of which is adjustable on the vertical plate and can be switched between a locked state and a released state. The impact-type high-pressure viscometer according to embodiments of this invention can achieve viscosity measurement under ultra-high pressure conditions, and the test results are close to actual working conditions, possessing advantages such as accurate and reliable detection and good repeatability.
