Description

one

This invention relates to devices for measuring the viscosity of opaque liquids. It can be used 9 industrial building materials, chemical, engineering, etc. The ball viscometer includes a cylinder, a ball filled with liquid, a device for counting the time of passage of a fixed part of the path. The drawbacks of the viscometer are design complexity and the presence of a graduated cylinder,

The closest technical solution to the proposed is a ball viscometer, which includes a cylinder, a ball filled with Liquid, devices for measuring the time of passage of a fixed part of the path with induction coils || 23

The disadvantages of this viscometer are the following: the complexity of the design, the need to install induction coils and the difficulty of returning the ball to its original position.

The purpose of the invention is to simplify the registration of the path and time of movement of the ball in the liquid.

Delivered; the goal is reached by the tem that the ball is suspended on a string

fixed length x one ie shoulders of the recorder. In addition, a vertical cylinder with a bolt is suspended in which the ball is located before the measurements start.

The drawing shows the scheme of the proposed ball viscometer.

The viscometer contains ball 1 suspended from thread 2 to the shoulder of arrow C and 4 recorder and po1)) checked in vertical cylinder 4 with shutter 5. Shp almost touches the surface of the test liquid filling the working capacity b. The npy) kHHa 7 serves to trim the shoulders of the arrow 3 of the recorder, which records on the moving tape 8. The gauge operates as follows. The movement mechanism of the tape 8 and the shutter 5, the ball 1, freezes and starts to fall in the liquid. During the release of the ball, the moment of forces acting on the left shoulder decreases and arrow 3 fixes this change in the form of a burst on the belt 8. When ball 1 moves to the entire length of the thread, it pulls the left shoulder of arrow 3 through itself 2, then stops. The end of the movement of the ball 1 is fixed by the arrow 3 on the tape with the next burst. After that, the ball and the & a thread and return to their original position. The depth L of the immersion of the ball in the Hcc fluid is determined by the length of the thread at which it is suspended, the time of movement of the ball in the fluid is determined by the formula g where Pj is the distance between the samples and the recorder; VA - skros; tapes of the ribbons. In magnitude of b b and t, c. fluid viscosity, based on the Stokes law, with the help of the famous Formulas. An invention of a viscometer for viscosity or viscosity of opaque liquids containing a ball on a thread / placed in a cylinder, a system for recording the path and time of its movement in a fluid with a recorder, characterized in that, in order to simplify the registration of the path and time of movement of the ball in the liquid and facilitate return it to its original position, the ball is suspended from one of the arms of the recorder on a thread of fixed length and placed in a vertical cylinder with a bolt fixed on the same shoulder of the recorder.
