Plural component coating application system with a compressed gas flushing system and spray tip flip mechanism

摘要

A system for purging a plural component coating application system including: a first pressure regulator for receiving an inert gas, providing the gas at a first pressure; a first valve; a first operator connected to the first valve capable of being controlled by a logic controller; a first check valve; a mixing manifold; a second pressure regulator for receiving an inert gas, providing the gas at a second pressure that is less than the first pressure; a second valve; a second operator connected to the second valve capable of being controlled by a logic controller; a second check valve; a static mixer in fluid communication with the mixing manifold; an outlet from the static mixer for receiving a connection to at least two spraying members; and where the second regulator is capable of providing the second pressure at a pressure that is less than one-fifth of the first pressure.

1. A method for coating a non-rotating pipe work piece comprising:
flowing a first component material and a second component material;
measuring at least one parameter of the flow of at least one component material;mixing the component materials;applying the mixed component materials to the outside surface of the work piece in an arcuate trajectory about the axis of the work piece, wherein the applying comprises oscillating at least two spray guns applying the mixed component materials about the work piece and traversing the at least two spray guns along an axial direction of the work piece;adjusting the frequency of oscillation of the at least two spray guns based at least in part on at least one parameter of the flow of the components and based at least in part on a selected coating thickness and based at least in part on a selected spray width and based at least in part on the outer diameter of the work piece; andadjusting the speed of traversing the at least two spray guns along an axial direction of the work piece
based at least in part on the oscillation frequency andbased at least in part on the selected spray width.
