摘要:
An applicator for spraying an elastomeric material comprises an applicator body having an internal bore and a fluid inlet for receiving a supply of the elastomeric material. A nozzle is coupled to the applicator body and has a discharge end with a spray outlet in fluid communication with the fluid inlet via a fluid passageway. A needle valve is slidably mounted within the internal bore for movement between a closed position for closing the fluid passageway, and an open position for opening the fluid passageway so as to spray the elastomeric material. An air cap is coupled to the applicator body adjacent the nozzle for providing an atomizing airflow and a fan control airflow. The needle valve has a tip portion shaped to extend through the nozzle so as to be substantially flush with the discharge end of the nozzle when the needle valve is in the closed position.
摘要:
A mobile coating system for coating an electrical insulator. The system includes an elongate shipping container that is transportable to a worksite, and a plurality of stations located within the shipping container. The stations include a loading station for loading an insulator to be coated, a coating station that includes a robotically controlled applicator for applying an elastomeric coating to the insulator, a curing station located after the coating station for curing the elastomeric coating, and an unloading station for unloading the coated insulator. The system also includes an endless loop conveyor for conveying the insulator through the plurality of stations. The endless loop conveyor has an elongated circular path.
