Description

A measure device that is arranged in lubricating oil demulsification degree to detect emulsion layer volume

Technical Field

The utility model belongs to a measuring tool, concretely relates to a measure device that is arranged in lubricating oil demulsification degree to detect emulsion layer volume.

Background

With the continuous development of economic construction in China, the demand for electric energy is continuously increased, the safe operation of a power plant has great influence on the economic construction, a steam turbine is used as important power generation equipment of the power plant, the operation of the steam turbine is reliable or not directly related to the safe production and stable power supply of the power plant, a steam turbine oil system is one of a plurality of main systems of the steam turbine, and the main function of the steam turbine oil system is to provide pressure oil of a regulating and lubricating system for a steam turbine generator bearing. If the turbine oil is contacted with water due to some objective reasons in the operation process, the oil and water are stirred by external force in the circulation process of the lubricating oil, so that the emulsification phenomenon is easy to occur. The emulsion can cause the oil film on the surface of the friction part to disappear, the lubricating performance of the lubricating oil is reduced, the bearing is overheated, and the speed regulating system fails or equipment is damaged; the water in the emulsion can accelerate the degradation of oil, so that the oil is deteriorated, and equipment corrosion and rust can be caused in severe cases. When the circulation rate of the lubricating oil is increased, the retention time of the lubricating oil in the oil tank is necessarily shortened, and the water cannot be effectively removed by utilizing a sedimentation method.

The ability of an oil product and water to form an emulsion and then to be divided into two phases is called the demulsification degree, in the national standard GB/T7605-2008, the demulsification degree is represented by the time for oil-water separation (namely the time required when the volume of the emulsion at the oil-water separation interface is equal to or less than 3 mL) after the stirring is stopped for the oil product emulsified by mechanical stirring at 54 ℃ by using oil and water with equal volumes. The property represented by demulsification degree is the capability of oil-water emulsion to re-separate two phases so as to ensure the lubricating property of lubricating oil, and is an important index for turbine oil. In order to prevent the emulsification of water and oil, it is required that the turbine oil has good anti-emulsification properties and the demulsification time is as short as possible to ensure the oil quality and the health of the equipment for a long time. The demulsification performance of the lubricating oil plays an important role in the lubricating performance of the lubricating oil, and the detection of the demulsification performance is an important detection method for judging the water intrusion resistance of a lubricating oil system, and belongs to an essential item for detecting the lubricating oil.

According to the related detection standard of demulsification degree, when a flat-bottom measuring cylinder is used for observing the oil-water separation step, key parameters such as water volume, oil volume, emulsification volume and the like need to be judged, and in the step, a detector needs to carefully observe the same scale of the volume and record the volume of each layer, so that the strength of the demulsification performance of the oil product and the availability of the oil product are judged. When the demulsification degree is detected, the following phenomena can occur in the emulsion layer:

(1) emulsion bubbles appear on the upper part or the lower part of the emulsion layer;

(2) the interface of the emulsion layer is irregular, and the upper interface or the lower interface is inclined;

(3) the emulsion layer is not obvious and the color is nearly the upper oil layer.

The reading of the volume of the emulsion layer at the end of the experiment is often influenced by a number of factors. For example, the volume of the emulsion layer is variable, so that the staying surface of the emulsion layer in each experiment is not exactly flush with the scale, the upper liquid surface or the lower liquid surface of the emulsion layer is not exactly positioned at the scale mark of the measuring cylinder, and at this time, estimation and reading are needed; in addition, in the estimation and reading process, an operator needs to measure the positions of the upper liquid level and the lower liquid level at the same time, and the difficulty is higher. In addition, its emulsion layer change speed is the not even state when detecting for some oil, and the emulsion layer volume changes constantly is a dynamic process, more needs to accomplish in the short time at the reading of detecting the terminal point to the emulsion layer volume so, reads the degree of difficulty of correct emulsion layer volume and can think of.
