Problems solved by technology

Adopting this method leads to the need for frequent sampling and testing during the test process. During the sampling process, it is necessary to interrupt the stirring process and try to be careful to ensure that the temperature of the tested oil sample is consistent with the processing temperature.
Due to repeated sampling, the number of oil samples gradually decreases, so there is a requirement for the amount of oil samples, and the fuel consumption is large, which is not a small trouble for long-distance sampling transportation (such as sampling and transportation from abroad).
In addition, the cleaning of crude oil in the sampler and viscometer is also a troublesome problem
The tediousness of the testing process also leads to the instability of test results and affects the enthusiasm of testers

Abstract

The invention is a testing device for crude oil viscosity, which is applicable to the determination of crude oil viscosity-temperature curves and the evaluation of heating and agent addition. The testing device comprises a programmable water bath (1), circulating water (13), a water jacket outlet (14), a water jacket inlet (19), a stirring motor (4) and a stirring paddle (16), a viscometer (5) and a rotor (10), and a rotating shaft (17); and the invention is characterized in that the device also comprises a crude oil processing device (3), a sleeve connector (6), a sleeve (7), a data transmission cable (8), a computer (9), a cover (15), and a rotating shaft connector (18). The crude oil processing device (3) is connected with the programmable water bath (1) through a water-bath inlet pipeline (2) and a water-bath outlet pipeline (12); the stirring motor (4) is connected with the stirring paddle (16) which is inserted into the crude oil processing device (3); the viscometer (5) is firstly connected to the sleeve connector (6), and then connected to the sleeve (7) which is inserted into the crude oil processing device (3) containing crude oil (11).

Description

technical field [0001] The invention relates to a testing device for crude oil viscosity-temperature curve measurement and crude oil viscosity evaluation by heating or adding additives. It relates to the technical field of piping systems. Background technique [0002] Crude oil viscosity-temperature curve measurement and heating or dosing evaluation are important contents of pipeline crude oil laboratory testing, and are the main technical methods for the rheological research and testing of crude oil under different conditions. The effects of heat treatment temperature, dosage, cooling rate, shear rate, final cooling temperature, etc. on the rheology of crude oil were clarified through tests. All of them involve the viscosity test of crude oil under different processing conditions (temperature history and shear history). The results of these tests are key technical references for crude oil pipeline transportation and storage processes. Viscosity testing itself has mature ...
