Technical specifications of HV-80E kerosene supersonic flame bore spray gun

The appearance of the spray gun is smaller, suitable for spraying the inner hole with a diameter of more than 90mm, and the fuel used: oxygen, kerosene, hydrogen, nitrogen, carrier gas, the spray gun is innovative, and has obtained invention patents.
The flame direction of the nozzle is designed to be angled, and the flame of the spray gun can be directly perpendicular to the internal surface of the workpiece.
Two rotation modes: (1) the spray gun does not move, the workpiece rotates, (2) the spray gun rotates, the workpiece does not move.
The main body of the spray gun can be made of lightweight high-temperature resistant material as an extension rod, and the extension rod can be customized with a range of 0.6-3 meters
The spray gun is equipped with a full closed-loop control system and adopts a mass flow controller to ensure the stability of spraying.

Q:What should I do if I find that the powder melts unevenly during the spraying process?

A: Pause the spraying, check the flame flow status to see if the temperature is not enough or unstable, and optimize the flame flow by adjusting the gas and accelerant flow. At the same time, check whether the powder feeding system is blocked or unevenly fed, clean the powder feeding pipe, check the operation of the powder feeding motor, and adjust the powder feeding rate or change the powder feeding mode if necessary.

Q:Is it easy for newbies to get started?

A: The first contact needs to be familiar, and it is not difficult to do it according to the operation guide. The preparation process is clear, the parameter adjustment is based on the basis, and the adjustment can be done well with more practice; Spraying pays attention to preheating, positioning, uniform speed movement and monitoring, and the task can be completed.
