Application of Thermal Spraying Technology in Spray Water Supply Pipe in Coal Winning Machine
LU Yunpeng
Abstract：The water supply pipe is the core component of the internal spray water supply device.Its sealing performance affects the working reliability of the internal spray device,and sealing failure will also have an adverse impact on the lubrication of the rocker drive system.The form and cause of failure of water supply pipe were analyzed.The wear resistance of sealing surface of water supply pipe was improved by using thermal spraying technology.Field application showed that its service life was increased by more than 3 times,and the reliability of internal spray water supply device was effectively improved.
