HV-80F Inner Hole Supersonic Spray Gun

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

• The appearance of the spray gun is smaller, suitable for spraying the inner hole with a diameter of 60-90mm, the fuel used: oxygen, kerosene, hydrogen, nitrogen, carrier gas, the spray gun is innovative, and has obtained the invention patent.

• 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.

1.Machinery manufacturing: Spraying wear-resistant and anti-corrosion coatings for the inner holes of hydraulic cylinders, oil cylinders and other parts to prolong the service life and reduce maintenance costs.

2.Automotive industry: Used in the inner hole of the cylinder barrel and piston ring groove of the automobile engine to improve performance and reliability, reduce wear and leakage, and optimize fuel efficiency.

3.Aerospace: Spraying on the tongue and groove of aero engine turbine blades and the inner hole of the casing to meet the requirements of high performance and high reliability.

4.Mold manufacturing: Strengthen and repair the inner hole of the mold, enhance the wear resistance, demoulding and thermal fatigue resistance, and improve the life and production efficiency.

5.Power industry: Spraying generator rotor journal and steam turbine blade inner hole to strengthen wear resistance and corrosion resistance to ensure the stable operation of equipment.

Product Operate Guide    

1. Equipment inspection: Check whether the appearance of the spray gun is damaged or deformed, and whether the connection parts are tight; Check whether the powder feeding and kerosene supply pipelines are smooth and free of leakage.

2. Spray gun installation: Install the spray gun firmly on the supporting equipment according to the identification, connect the gas, powder and oil circuits and confirm.

3. Preparation of powder and kerosene: Select the appropriate powder and pour it into a sealed powder feeding container; Add clean kerosene to the storage tank, do not exceed the specified capacity, and check the liquid level display.

4. Flame flow speed and power adjustment: Enter the setting interface when booting up, adjust the flame flow speed according to the situation of the inner hole, adjust the power synchronously, reduce the speed and power of the small inner hole, and increase the power of the large inner hole appropriately.

5. Powder feeding adjustment: Set the powder feeding amount on the panel according to the coating thickness requirements, and increase or decrease according to the spraying effect. Cleaning and maintenance: After the equipment is turned off, clean the blowing powder and kerosene pipelines, wash and dry the container and storage tank, wipe the spray gun, check the wear of parts, and replace it in time if it is serious.

Q1: Will the high flame velocity damage the surface of the inner hole?

A: Usually not. The optimized design of the spray gun can reasonably distribute the flame flow energy, adjust the parameters according to the operation guide, and accurately adjust the material and size of the inner hole, which can ensure the non-destructive and high-quality spraying.

Q2: What is the better coating quality than traditional spray guns?

A: There is radial powder feeding technology, the powder is dissolved, the distribution is good, and the coating is dense; The patented parts ensure sufficient combustion, no carbon deposits, less impurities, and excellent hardness, wear resistance, adhesion and other indicators.

Q3: 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.

Q4: How to deal with the abnormal sound of spraying?

A: Stop spraying immediately, check whether the powder is fed smoothly, whether there are foreign substances in the combustion chamber and nozzle, whether the kerosene supply is normal or not, clean or repair the problem, and do not contact the manufacturer.
