Abstract

Изобретение относитс  к нефт ной промышленности и может быть использовано дл  удалени  парафино-смолистых отложений с внутренней поверхности насоснокомпрессорных труб 8. Цель - повышение эффективности работы за счет более полной очистки обрабатываемой поверхности. Скребок состоит из корпуса (К) 1, подвешенного на проволоке 2. На концах К 1 размещены турбины (Т) 5, а между ними - стабилизатор 6. На наружной поверхности Т 5 размещены по спирали штыри 7. Направление захода каждой спирали противоположно вращению Т 5, которые выполнены с возможностью вращени  в противоположные стороны. Скребок размещают внутри труб 8. Встречный поток жидкости вращает Т 5, и штыри 7 срезают парафин. Несовпадение вращени  Т 5 и направлени  спирали увеличивает ширину очищаемой поверхности за один оборот. Очистка по двум винтовым лини м разного захода обеспечивает полную очистку поверхности. Снабжение скребка стабилизатором 6 исключает вращение К 1. 4 ил.The invention relates to the petroleum industry and can be used to remove paraffin-resinous deposits from the inner surface of pump compressor pipes 8. The goal is to increase work efficiency through more complete cleaning of the treated surface. The scraper consists of a body (K) 1 suspended on a wire 2. Turbines (T) 5 are placed at the ends of K 1, and a stabilizer 6 is placed between them. Spirals 7 are arranged in a spiral on the outer surface of T 5. The direction of approach of each spiral is opposite to rotation T 5, which are rotatable in opposite directions. The scraper is placed inside the pipe 8. The counter-flow of liquid rotates T 5, and the pins 7 cut paraffin. The mismatch between the rotation of T 5 and the direction of the spiral increases the width of the surface to be cleaned in one turn. Cleaning along two helix lines of a different approach ensures complete cleaning of the surface. Supply scraper stabilizer 6 eliminates the rotation of K 1. 4 Il.
