Abstract: In order to meet the needs of production,several important relations among structural and operating parameters of hydrocyclone are attained based on experiment analysis.According to flow field properties,if overflow pipe is extended into the case in some depth,and the operating parameters are reasonable,the pre separation efficiency is promoted with the enlargement of dia meter of overflowing vent.Based on the research,some samples have been developed,and put into field applicaiton.It is found that when the production fluid which contains 85% water is preseparated by operating the samples,the water content in overflowing fluid is less than 30%,and oil content in downflowing water drops about 1%.It reaches the index of quality of processed water These machines can be generalized to field application.
