FIELD: mining.SUBSTANCE: method presumes the action in view of types of deposits on the cleaned surface by setting of the respective values of physical parameters of the effecting working medium, geometry of a cavitator and its position with reference to the cleaned surface:Pand Ps, where- relative distance from the cavitator outlet to the cleaned surface, P- dynamic pressure downstream the cavitator, Ps - static pressure in the flooded cavity. Values of the parametersand Pc are pre-set within the limits:P=5-45 MPa. Static pressure Pin the flooded cavity is pre-set according to the conditionwith providing of pulsation of the jet cavitating flow with a variable frequency and achievement of a resonance of layers of deposits. The pulsation of the jet cavitating flow is provided using a sweep generator. Occurrence of resonance of layers of deposits is identified by growth of concentration of pollution of destroyed layers in the taken-away flow, the frequency of pulsation of the jet cavitating flow is registered, at this frequency the cleaned surface is processed further.EFFECT: improvement of efficiency of cleaning and maintenance of wells and pipelines increases.9 cl, 5 dwg |
