Problems solved by technology
Different from gravity separation equipment, centrifugal separation equipment often discharges oil-water mixture at the oil outlet, and there is a certain emulsification phenomenon. In order to ensure the sustainability of the test and the accuracy of the measurement data, it is necessary to control the The oil working medium is continuously recovered, and the emulsion and water are prevented from entering the oil tank to cause measurement errors
Existing test devices often cannot fundamentally solve these problems

Description
technical field [0001] The invention belongs to the technical field of oil-water separation, and in particular relates to an oil-water separation test device relying on gravity reflux. Background technique [0002] In the petroleum and chemical industries, oil-water mixtures often flow in pipes, and the process of oil-water separation is often an essential part of production. In recent years, people have researched and developed many oil-water separation devices, among which, the oil-water separators using centrifugal technology are often smaller in size and more suitable for use in the production process. [0003] For the oil-water separator using centrifugal technology, due to the different methods of generating centrifugal force and the structural parameters of the separator, the separation effect and applicable flow range are also different, which requires a special test device for comprehensive evaluation of its performance , and determine the direction of optimization...
