System for measuring content of trace moisture in sample difficult to gasify

Abstract

The invention provides a system for measuring the content of trace moisture in a sample difficult to gasify. The system is characterized in that a storage container is used for storing a sample, a protective gas conveying assembly is connected with a gas inlet through a gas conveying pipeline, a heating sleeve is arranged on the storage container in a sleeving manner, a heating belt is wound in the heating sleeve and is used for heating the storage container so as to gasify moisture in the sample, a coulombic method electrolytic tank is provided with a gas inlet and a gas outlet, the gas inlet and the gas outlet are connected through a gas guide pipeline, phosphoric acid is coated on the electrode of the coulombic method electrolytic tank, a coulombmeter is connected in series in the electrolytic circuit of the coulombic method electrolytic tank, a control unit is electrically connected with the coulombmeter and a display device, and the control unit is used for displaying data measured by the coulombmeter on the display device. The technical scheme provided by the invention has the beneficial effects that the problem that the trace water content of viscous liquid, solid and other samples which are not easy to gasify cannot be measured by adopting an electrolytic method can be solved, the sample is easy to replace, the accuracy is high, the electrolytic tank can be repeatedly utilized, and the rapid detection of the trace water content in the sample can be realized.

Description

technical field [0001] The invention relates to the technical field of trace moisture content detection, in particular to a system for measuring trace moisture content in samples that are not easily vaporized. Background technique [0002] Trace amounts of moisture have a great impact on many aspects such as oil products and materials. Jet fuel contains a small amount of water. When the aircraft is flying at high altitude, the water condenses into ice particles to block the oil circuit, causing safety hazards; water in lubricating oil will destroy the lubricating film, make the lubrication cannot be performed normally, and increase the wear of the machine parts. In addition, the inorganic salts brought by the water will also increase the corrosiveness of the lubricating oil and aggravate the corrosion of the parts. When the lubricating oil containing water is used to work in a high temperature environment, the vaporization of water will also destroy the lubricating film. Ex...
