Abstract:The topic of this graduation design is: oil well paraffin device design. This design is for flowing well conceived a mechanical automatic scraping wax device. Paraffin device by ground hoist, wellhead lubricator, borehole scraper, borehole aggravating piece and process control, etc. By program control ground hoist positive &negative, by wire pulling scraper for reciprocating movement up and down within the tubing, the junction of tubing inwall proves the scrape wax. Users only need to set the time and the number of paraffin wax, to use the device automatically scraping wax. First information via the learned information combined with the feasibility plan, in the analysis, scheme comparison, select material, parts structure design, main parts, to ensure that the design is reasonable and practical. Ground in the design of the hoist in the design of the most complex, is the main part design, including parts, more so on the careful analysis. Final design could satisfy the requirement of subject a scraping wax mechanical automatic device.
