Research of processes and control parameters in the system for ultrasonic cleaning of railway switches with vortex effect used
A new method of cleaning railway switches has been proposed, which is realized by transmitting compressed air from a pneumatic pipeline through a vortex pipe and an ultrasonic siren for the most effective snow-ice destruction and melt. As a generator of hot compressed air for successful snow-ice melting, a vortex pipe of counter flow type has been used. As an ultrasonic generator for ice destruction, an ultrasonic static siren has been used. Structural realization of cleaning system has been offered by doing complex interaction of such devices as an ultrasonic static siren and a vortex pipe. To present the processes and system parameters in a more detailed way, the article contains the structure and the drawing of a system for cleaning railway switches with vortex effect and ultrasound used. Functional principle has been explained. Experimental research results have been presented for the processes and control parameters in the system for ultrasonic cleaning of railway switches with vortex effect used. Experimental research analysis confirms the high level of conformity between a mathematical model and a real process as a divergence degree does not exceed 1.5-4% for experimental data. Cleaning with vortex effect used allows removing not only the top, not stamped snow layer but also the stamped snow layers and ice (in comparison with the cleaning with compressed air used which allows removing only the top layer of not stamped snow). Cleaning with an ultrasonic siren used allows removing snow form an ice block and polishing the processed part of its surface.
