Abstract
A thermal sprayer system includes an injector conduit in communication with an injector and a first valve for selectively directing a coating fluid through the injector conduit. A flush fluid conduit is in communication with the injector conduit for directing a flush fluid through the injector conduit. A pressurized air conduit is in communication with the injector conduit for directing a pressurized fluid through the injector conduit.
Claims15
A thermal sprayer system comprising:
- an injector conduit in communication with an injector;
- a first valve for selectively directing a coating fluid through the injector conduit, wherein the first valve is located downstream of a reservoir for storing the coating fluid;
- a flush fluid conduit in communication with the injector conduit for directing a flush fluid through the injector conduit;
- a pressurized air conduit in communication with the injector conduit for directing a pressurized fluid through the injector conduit;
- and
- a pressure sensor for monitoring a fluid pressure in the injector conduit, wherein the pressure sensor is configured to monitor a pressure of the injector conduit at a location of the injector conduit downstream of the first valve, the flush fluid conduit, and the pressurized air conduit.
