Description
Technical field
The utility model relates to a kind of moisture content detection device, especially a kind of water content in oil pick-up unit.
Background technology
Oil product has become indispensable article in our productive life, especially industrial oil product is the lifeblood of plant equipment.In actual application, water inlet is a principal element that causes the oil quality deterioration in the oil.In order in time to find, prevent the oil product deterioration, will be regularly or irregularly detect moisture in the oil product, present topmost detection means is to send the laboratory after extracting oil sample, utilizes evaporation method or titrimetry to carry out moisture and detects.An existing patent No. is 200720027312.7 and is called that the utility model of " the lubricated simple and easy qualitative detection device of water content in oil ultrasonic vibration " discloses the simple and easy qualitative detection device of a kind of lubricated water content in oil ultrasonic vibration, it is characterized in that it is made of tank (1), ultrasonic vibrator (2), control enclosure (3), ultrasonic vibrator (2) is fixed on the interior diapire of tank (1), ultrasonic vibration controller (4) on control enclosure (3) internal fixation, ultrasonic vibrator (2) is connected with ultrasonic vibration controller (4) by lead.Should lubricate the simple and easy qualitative detection device of water content in oil ultrasonic vibration, low, the consuming time weak point of cost, easy to operate, safe in utilization.But can only do one and intuitively judge whether moisture in the lubricating oil, can not carry out quantitative measurment, await improving.
Summary of the invention
Technical problem to be solved in the utility model be provide at the above-mentioned state of the art a kind of reasonable in design, simple in structure and can detection by quantitative the device of water content in oil content.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a metal probe is installed in the metal oil conduit of the vertical direction that oil product flows, fix by pipe fitting and insulation spacer sleeve between probe and the metal tube, guarantee that it is not communicated with, two terminals of capacitance detecting instrument are connected with metal tube with probe respectively.
As improvement, described probe is selected metal, rod-shaped (being preferably stainless steel) for use, is fixed on metal oil conduit central authorities by pipe fitting screw thread or flange mode, and probe equates with distance on the inside pipe wall all directions.Insulation sleeve sealing and fixing between probe and pipe fitting or the flange.
Improvement again, described probe is the bare metal section in the fluid contact portion that oil pipe flows vertically upward, the place that contacts with the mobile fluid of other directions is the insulation sleeve protection, and is accurate, stable to guarantee measured value.
Improve, described capacitance detecting instrument is known maturing apparatus again: the digital capacitance detector, can load one or more burning voltages, and can measure 60 groups of data p.s. at most, and data read and writing function are arranged.
Improve again, two terminals of described capacitance detecting instrument are connected on respectively on probe and the metal oil tube wall, the fluid of probe, metal oil conduit and intermediate flow is formed a capacitance structure, along with the variation of water content in oil content, and the also linear variation of the capacitance that the insulativity of fluid also changes, records.
As further improvement, data that described capacitance detecting instrument is measured and the contrast of standard aqueous oil sample, demarcation determine that it changes slope, can obtain corresponding moisture data according to its capacitance.
Compared with prior art, advantage of the present utility model is: utilize the fluid of probe, metal oil conduit and intermediate flow to form electric capacity, its capacitance generation linear change of difference because of moisture in the fluid, capacitance that records and standard oil sample correlation calibration can obtain the moisture data of fluid, not only project organization is simple, easy to make, and the accuracy height, be worthy to be popularized very much.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the water content in oil pick-up unit of present embodiment is that a metal probe 2 is installed in the vertical section of metal oil conduit 1, and two terminals of capacitance detecting instrument 3 link to each other with metal probe 2 with metal oil conduit 1 respectively.
Described metal probe 2 is cylindrical shaft-like thing, by insulation spacer sleeve 6 and pipe fitting 5 and 1 airtight connection of metal oil conduit.Probe 2 equates with distance on managing 1 inwall all directions.In metal oil conduit, the flow direction of fluid 4 is to flow to the right after upwards from sagging.
Described capacitance detecting instrument 3 is known matured product, can load one or more burning voltages, can measure maximum 60 groups of data p.s., can transfer choosing as required, has data read and writing function.
Principle of work of the present utility model is: the fluid 4 (can be considered insulant) that flows in metal oil conduit 1, metal probe 2 and the pipe is formed a capacitance structure, the terminals of capacitance detecting instrument 3 link to each other with metal probe 2 with metal oil conduit 1 respectively, and instrument is given this capacitance structure cycle on-load voltage and measured its capacitance.Fluid is as a kind of insulating medium, along with the variation of moisture in the oil product, and its insulativity difference, the linear variation of capacitance that records.By demarcation to two groups of different moisture content reference fluid capacitances, can obtain the corresponding linear relationship of electric capacity and moisture, whenever record a capacitance and can obtain corresponding water content in oil content value, fast, accurately, result of use is very good.
