The accessories for supersonic spraying equipment in the thermal spraying industry are core matching components tailored for high-end thermal spraying equipment such as High-Velocity Oxy-Fuel (HVOF) spraying and supersonic plasma spraying. They cover a full range of core parts including core spray gun components (wear-resistant tungsten carbide nozzles, zirconia ceramic liners, and high-temperature resistant alloy gun bodies), precision powder feeding system accessories (variable-frequency powder feeder rotors, wear-resistant powder feeding pipes, and quantitative powder feeding valves), high-pressure airflow control components (precision pressure reducing valves, high-temperature resistant airflow nozzles, and pressure sensors), cooling and protection accessories (forced water cooling jackets, heat-insulating protective covers, and anti-splash coatings), as well as automation-adaptive components (servo-driven actuators, stroke limit switches, and signal transmission modules). All accessories are manufactured with high precision from high-wear-resistant, high-temperature-resistant, and corrosion-resistant special alloy materials (such as Inconel alloys, silicon carbide ceramics, and cemented carbides). Among them, the spray gun nozzles adopt an integral sintering forming process with an inner hole precision of ±0.01 mm, ensuring the stable ejection of supersonic airflow and uniform atomization of powder; the quantitative powder feeding valves are equipped with high-precision flow sensors, featuring a powder feeding accuracy error of ≤±1%, which can be accurately matched with alloy and ceramic powders of different particle sizes (such as WC-Co, NiCr-Cr₃C₂, and Al₂O₃-TiO₂); the forced water cooling jackets adopt a spiral flow channel design, increasing cooling efficiency by more than 30% and effectively controlling the spray gun temperature below 200℃ to avoid the impact of high temperatures on accessory performance. These accessories boast core advantages including wide adaptability, high operational stability, long service life, and convenient maintenance. They can significantly improve the spraying efficiency, coating bonding strength and uniformity of supersonic spraying equipment, and reduce equipment downtime caused by faults. Backed by professional R&D and manufacturing capabilities, we can provide customized accessory solutions for supersonic spraying equipment of different brands and models (such as Metco and Praxair series), covering the entire process of accessory size customization, material optimization and selection, and performance parameter matching. These accessories are widely used in high-end thermal spraying fields including aero-engine blade strengthening, high-end mold surface modification, wear-resistant repair of petroleum drilling and production equipment, and anti-corrosion strengthening of wind power components, meeting the requirements for the efficient and stable operation of various supersonic spraying equipment and the preparation of high-precision coatings.
