DEVELOPMENT OF AN IN-PIPE ROBOT USED FOR CYLINDER OF SUCKER PUMP LASER INNER SURFACE MODIFICATION

The systematical structure and operation principle of an in-pipe robot used for cylinder of sucker pump laser inner surface modification are developed. The system combines laser surface modification with in-pipe robot technologies, and it performs with good function, high reliability, good controllability and low cost. The experimental results shows that it is a new and effective method.
