Key parameters of working bodies are determined, which provide simultaneous removal of an old covering and clearing of an external surface of pipes to a degree 2-3 ДСТ 9. 402-80 (Swedish standard SA 2.5) at productivity of 1,6 m / min, satisfy to sanitary norms on noise level and vibration and requirements of Gosgortekhnadzor on fire safety. Geometrical parameters of the cutting tools providing clearing of pipes up to a degree 2 - 3 ДСТ 9.402 - 90, not cut longitudinal both cross seams, and pipes removing from a surface old polyethylene isolation as дробленной shavings are designed. The carried out (spent) experimental researches have shown high efficiency of offered working bodies. The received results have scientific novelty and the practical importance. On the basis of carried out (spent) theoretical and experimental researches the technique of engineering calculations flexible itself of center's working bodies of the clearing machines intended for removal old polyethylene of coverings at repair work is developed. The received results will be used in designing at creation and development of new clearing machines.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
