The principle of detecting the water content of the crude oil by using electromagnetic waves is as follows: the electromagnetic wave is used as the working frequency, and the electromagnetic wave signal with constant amplitude and stable frequency is transmitted into the water-containing crude oil through the transmitting device. The capacitance changes when the oil-water ratio changes due to the fact that the dielectric constant difference between oil and water is large, so that the oscillation frequency changes, and the water content value of a medium in a pipeline can be measured by measuring the oscillation frequency. According to the water content in the oil, the detection device transmits the signal of different absorbed electric energy caused by different water content of the crude oil to the instrument processor. After being processed, amplified and linearly corrected, the standard electric signal which changes with the water content in the oil is output and is converted into a water content proportion; the working principles and functions of the electromagnetic wave emitting device, the detection device for detecting and monitoring the electromagnetic wave energy in the medium, the analog-to-digital converter, the processor and the control device in the application are consistent with the technical scheme disclosed by the oil water content monitor disclosed in the Chinese patent with the application number of '201220676751.1'.
The specific working principle of the detection device is as follows: when the device is used, crude oil flows through the channel 2 in the electrode shell 1, and when the crude oil passes through the channel 2, the working electrode 4 is used for absorbing electric energy in the crude oil, and transmits the processed, amplified and linearly corrected signal to the single chip microcomputer for processing through the circuit board 5, so that the water content in the oil is obtained; because the channel 2 is a horizontal straight-through structure, crude oil cannot be deposited in the channel 2, frequent cleaning is not needed, and blockage cannot occur.
In order to facilitate the arrangement of elements, the outer diameters of two ends of the channel 2 are expanded outwards to form a horn shape, and the outer diameter of the outermost channel 2 is consistent with the inner diameter of the electrode shell 1; so that a space for mounting the working electrode 4 and the circuit board 5 exists between the middle of the channel 2 and the motor housing.
In order to facilitate detection, the outer side of the channel 2 is sleeved with filled plastic 3, and the working electrode 4 is arranged on the outer side of the filled plastic 3.
In order to improve the waterproofness of the device, a sealant 9 is filled between the channel 2 and the electrode shell 1, and the sealant 9 is formed by mixing epoxy resin, polytetrafluoroethylene and a curing agent; the leakage of moisture through the gap between the channel 2 and the electrode housing 1 is avoided, and the failure rate of the circuit board 5 is reduced.
In order to enhance the sealing performance of the connection, a sealing ring 8 is arranged at the joint of the detection head 6 and the electrode shell 1, and the sealing ring 8 is an O-shaped sealing ring 8.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
