Device and method for measuring viscosity of petroleum

Abstract

The invention provides a device and a method for measuring viscosity of petroleum. The device comprises a drawing mechanism, a rotating mechanism, a detection mechanism and a control mechanism; the drawing mechanism is an electromagnet; the electromagnet comprises an armature and a reset spring, and is started under the control of the control mechanism; the upper end of the rotating mechanism is connected with the armature; the lower end of the rotating mechanism is arranged in a to-be-measured petroleum body; the middle of the rotating mechanism is provided with a support shaft; the armature is capable of driving the rotating mechanism under the attraction drawing of the electromagnet to rotate along the support shaft; the detection mechanism is used for detecting the rotating angle or / and rotating displacement or / and rotating time of the rotating mechanism; the control mechanism is used for controlling the starting of the drawing mechanism, and calculating the viscosity of the to-be-measured petroleum body according to parameters detected by the detection mechanism. Full-automatic measurement is realized by the device and the method provided by the invention, so the device and the method are high in measurement precision, low in cost, and easy to popularize and apply.

Description

technical field [0001] The invention relates to the field of liquid viscosity measurement, in particular to a petroleum viscosity measurement device and a measurement method. Background technique [0002] As an important indicator in petroleum products, the property of viscosity is crucial to the biodegradability of oil. In daily life, viscosity is of great significance to the quality, performance and use of various products derived from petroleum, and it is also a key factor determining the flow characteristics of petroleum products. When the viscosity of the liquid is too high, the liquid oil film will be large, and the performance of the liquid will be good in some aspects, such as lubrication; when the viscosity of the liquid is too small, it will not be able to form a sufficiently large or thick oil film, which is to increase friction. It is a kind of damage to the machinery that uses oil for a long time. [0003] The kinematic viscosity of a liquid is the ratio of th...

Problems solved by technology

For example, during the experiment process, the surveyor must manually adjust the instrument. In this case, the surveyor will be required to have very good skills, and the counting process will be too manual. The process is not only cumbersome, but also reduces the accuracy. , there is also a large uncertainty factor for the calculation accuracy of the final viscosity, not only that, but also increases the workload of the measurement personnel in the aspect of measurement data management
