Description

Double constant temperature bath kinematic viscosity testing device

Technical Field

The utility model relates to an oil viscosity testing arrangement technical field especially relates to a two constant temperature bath kinematic viscosity testing arrangement.

Background

The viscosity is an important index of the oil and is an indispensable parameter in petrochemical engineering design. During the use and transportation process of the oil product, the viscosity is accurately measured, and the quality of the oil product can be strictly controlled. The kinematic viscosity measurement method has various methods, and the domestic current measurement methods comprise a capillary tube measurement method, a rotation measurement method, a falling ball method, a vibration method, a flat plate method and a viscosity cup method. Among them, the gravity glass capillary measurement method is the most accurate method among the existing measurement methods, and is also the most commonly used method.

The method for measuring kinematic viscosity of oil by glass capillary is that under a certain constant temp. the time of a certain volume of liquid flowing through a calibrated glass capillary viscometer under the action of gravity is measured, and the product of capillary constant and flow time of viscometer is used, i.e. the kinematic viscosity of liquid is measured at said temp..

The constant temperature environment provided for the viscometer during the measurement of the dynamic viscosity is usually realized by adopting a constant temperature bath, and the constant temperature bath is widely applicable to chemical, biological and physical laboratories which need to work under the conditions of low temperature, normal temperature or high temperature, and is a necessary device for laboratories of medical and health, chemical industry, food industry, metallurgical industry, colleges and universities, scientific research, genetic engineering, high molecular engineering and the like.

The kinematic viscosity measurement can be carried out at different temperatures, for example, diesel oil is usually required to measure the kinematic viscosity at 20 ℃, gear oil, hydraulic oil, heat transfer oil and the like are usually required to measure the kinematic viscosity at 40 ℃, heavy fuel oil, residual oil and the like are usually required to measure the kinematic viscosity at 80 ℃ or 100 ℃, the viscosity index is an important index for guiding the production of the motor oil, and the viscosity index is required to be calculated by measuring the kinematic viscosity at 40 ℃ and 100 ℃. The thermostatic bath of the viscometer needs to be maintained at different temperatures and is more likely to need to be switched back and forth at different temperatures.

When switching between different target temperatures, the temperature rising and reducing process is very long, under the condition of room temperature 25 ℃, the temperature of a constant temperature bath filled with 5L of methyl silicone oil is reduced from 100 ℃ to 40 ℃, under the condition of no auxiliary refrigeration, the time required for naturally cooling and stabilizing to the target temperature of 40 ℃ is about 3.5 hours, and under the condition of higher room temperature, the temperature reducing time is longer, so the testing efficiency is greatly reduced.

Most of users needing to switch the temperature during the viscosity test have fixed temperature points, for example, if the motor viscosity of the vehicle lubricating oil needs to be tested at 40 ℃ and 100 ℃ to calculate the viscosity index, the user only needs to control the temperature of the constant-temperature bath at two temperature points of 40 ℃ and 100 ℃. Many users purchase two viscometers with temperature control of 40 ℃ and 100 ℃ respectively to improve the testing efficiency.

Therefore, the double constant temperature bath kinematic viscosity testing device is designed, so that a plurality of groups of temperature comparison can be carried out simultaneously during a viscosity test, interference behavior is avoided, the kinematic viscosity test efficiency is improved, and the direction of further improvement is provided.
