Device for automatic determination of emulsion breaking degree of oil product and determination method

Abstract

The invention relates to a device for automatic determination of the emulsion breaking degree of an oil product and a determination method. In the existing equipment for determination of the emulsionbreaking degree of the oil product, the automation degree is low, a laboratory technician needs to observe the oil-water separation condition in the whole process and the working efficiency is not high. The determination method comprises the following steps: by utilization of the Lambert-Beer law, stable monochromatic light transmits through a measuring cylinder containing the oil product, due todifference of light transmittance of the oil product, water and stirred emulsion, the transmitted lights are different in intensity, the light transmittance of each layer can generate jump, the jump part of the light transmittance is adopted as a dividing part of the layer and another layer, the height of each layer is equal to a product between the moving time of transmitting pools approximatelyequal in light transmittance multiply the moving speed of the transmitting pools, a control system calculates out the height of each layer automatically so as to judge a test endpoint. A lightproof cover with manual opening and closing is also designed at the periphery of a water bathtub, the test endpoint can be artificially judged by pulling and opening the lightproof cover and selecting a manual mode. The device and the determination method have the advantages that unattended determination for the emulsion breaking degree of the oil product is realized and the automation level of the determination process is improved.

Description

technical field [0001] The invention relates to a device and a measuring method for automatically measuring the degree of demulsification of oil products, which are used for automatic and accurate determination of the degree of demulsification of oil products. Background technique [0002] With the continuous development of my country's economic construction, the demand for electric energy continues to grow. The safe operation of power plants has a major impact on economic construction. As an important power generation equipment for power plants, steam turbines are directly related to the safe production and stability of power plants. Power supply, turbine oil system is one of the nine major systems of the steam turbine, and its main function is to provide pressure oil for the adjustment and lubrication system of the turbine generator bearing. Oily emulsification not only deteriorates the adhesion of the lubricating oil, but also destroys the oil film formed by the lubricatin...

Problems solved by technology

[0003] At present, the degree of automation of the oil demulsification degree measurement equipment is not enough, and the experimenter needs to observe the oil-water separation throughout the process, and manually determine the demulsification time according to the standard. For example, the Chinese patent with the application number CN201510375196.7 is not efficient and cannot be automated. determination
