Abstract

The invention discloses a crude oil water-content on-line tester. The crude oil water-content on-line tester comprises a valve body with a valve cavity. The valve body is provided with an oil inlet and an oil return opening communicated with the valve cavity. The oil inlet is connected to an oil inlet pipe which is provided with a circulating oil pump and an oil inlet pipe stop valve and is connected to an oil transportation main pipe. The oil return opening is connected to an oil return pipe which is provided with an oil return stop valve and is connected to the oil transportation main pipe. A water-content tester probe is arranged at one of two opposite sides of the valve body and a push-pull rod is arranged at the other one of the two opposite sides of the valve body. Front parts of the water-content tester probe and the push-pull rod stretch into the valve cavity. A rear part of the push-pull rod stretches out of the valve body. A fluorine rubber sleeve with a centre hole is fixed to a front end of the push-pull rod. The centre hole of the fluorine rubber sleeve aims at the water-content tester probe and sizes of the centre hole and the water-content tester probe are matched. A rear end of the push-pull rod is connected to a push-pull power plant. The crude oil water-content on-line tester realizes automatic timing and regular wax removal, avoids stopping of the oil transportation main pipe, avoids dismounting and manual cleaning of the water-content tester probe, realizes accurate water-content tester detection data, and realizes simple and reliable crude oil water-content on-line detection.

Description

Technical field: [0001] The invention relates to an online water content measuring instrument for crude oil, which is used for online measuring the water content of crude oil transported by pipelines. Background technique: [0002] The water content of crude oil is one of the key indicators related to the economic interests of buyers and sellers. Although the various minerals in crude oil are diverse and complex, the factor that has the greatest impact on the measurement accuracy of the water content analyzer is the wax on the probe of the water content analyzer. Due to the great difference in the wax content of the crude oil in each oilfield and the difference in the transportation temperature, the probe of the water content analyzer will produce wax hanging phenomenon irregularly. After the probe is waxed, the wax film outside the probe will form a medium layer between the probe and the crude oil. With the change of the medium layer, the measured results of the measuring i...
