Problems solved by technology

The key to the dynamic sampling work of the pipeline is the representativeness of the oil samples taken, which must truly reflect the overall situation of the crude oil passing through the pipeline at that time. The laboratory work is meaningless and may cause serious economic losses to the enterprise

Abstract

The invention discloses an on-line automatic crude oil sampling system. The on-line automatic crude oil sampling system comprises a probe, a first electromagnetic valve, a filter and a main driving pump which are sequentially connected, wherein an outlet of the main driving pump is connected with a first inlet of a third three-way valve; a second inlet of the third three-way valve is connected with a blowing device; an outlet of the third three-way valve is connected with an inlet of a sampling device; an outlet of the sampling device is connected with an inlet of a fourth three-way valve; a first outlet of the fourth three-way valve is connected with a first inlet of a fifth three-way valve; a second outlet of the fourth three-way valve is sequentially connected with a heat tracing system and an on-line water analysis and detection system; the on-line water analysis and detection system is connected with an outlet and a second inlet of the fifth three-way valve; and an outlet of the fifth three-way valve is sequentially connected with a pressure transmitter, a one-way valve and a second solenoid valve. The system can achieve the on-line detection of the crude oil pipeline and the automatic cleaning function after the detection.

Description

technical field [0001] The invention relates to an online automatic sampling system for crude oil. Background technique [0002] The measurement of crude oil as a commodity in the transfer process can only be traded fairly if it is scientific, fair and accurate. In the process of crude oil transfer and measurement, in order to determine the water content, sulfur content, density and other parameters of oil products, it is necessary to carry out laboratory analysis on oil products. At present, crude oil and refined oil are transported by long-distance large-diameter pipelines, and the daily delivery volume of pipeline transportation is very large. It is impossible to measure all oil products, and only the method of taking oil samples can be used. The key to the dynamic sampling work of the pipeline is the representativeness of the oil samples taken, which must truly reflect the overall situation of the crude oil passing through the pipeline at that time. The laboratory work...
