2086 Inner Hole Plasma Spray Gun

Introduction

As the most popular plasma spray gun, we offer a replica of the American SG100-2086 inner bore plasma spray gun. The main gas of the gun is argon or nitrogen, and the auxiliary gas is hydrogen. The spray gun provides the following accessories: nozzles, powder tubes and powder holders, water cables, electrode heads, insulators, sealing rings, special tools, etc. The gun is used in the production of thermal spray operations and can work continuously for a long time.
This spray gun is widely used by users around the world today and proves to be the most stable and reliable universal plasma spray gun, the spray gun has hundreds of customers in China, and the application is mature in the thermal spraying industry.
Working current: 100 ~ 1000A, working voltage: Ar+H2 30 ~ 80V, N2+H2 37 ~ 80V. The gun is used in the production of thermal spray operations with a maximum output of 45KW.
Plasma spraying is carried out by plasma arc, ion arc is a kind of compression arc, compared with the free arc, its arc column is small, the current density is large, and the degree of gas ionization is high, so it has the characteristics of high temperature, energy concentration, and arc stability

The gun uses a non-diverted arc: an arc of plasma created between the cathode and the nozzle. In this case, the positive electrode is connected to the nozzle, the workpiece is not charged, an electric arc is generated between the cathode and the inner wall of the nozzle, and the working gas is heated by the arc between the cathode and the nozzle, causing full or partial ionization, which is then emitted by the nozzle, forming a plasma flame (or plasma jet).
The SG100-2086 gun's powder feed design allows it to deliver powder at low pressure in the powder feeder, unlike some guns that require a high pressure powder feeder, resulting in improved process stability.

Technical parameters and characteristics of the inner bore spray gun

• The main gas is argon or nitrogen, and the auxiliary gas is hydrogen.

• The spray gun provides the following accessories: nozzles, powder tubes and powder holders, water cables, electrode heads, insulators, sealing rings, special tools, etc. The gun is used in the production of thermal spray operations and can work continuously for a long time.

1.Machinery manufacturing: It is used for the surface treatment of the inner bore of engine blocks, hydraulic cylinders and other parts to improve wear resistance and sealing, such as enhancing the wear resistance of engine cylinder walls and improving power and fuel economy.

2.Automotive industry: It can spray engine cylinder barrel, crankcase and other internal bore parts to improve performance and quality, reduce fuel consumption emissions, and is also used for remanufacturing to repair worn bores and reduce maintenance costs.

3.Aerospace: It can spray the inner hole parts such as the combustion chamber and turbine blade tongue and groove of the aero engine to enhance the performance of high temperature resistance and thermal fatigue resistance to ensure the safe operation of the engine.

4.Petrochemical industry: Anti-corrosion and wear-resistant coating can be sprayed on the surface of the inner hole of pipeline, reactor and pump, so as to improve corrosion resistance and erosion resistance and reduce equipment maintenance costs.

5.Mold manufacturing: Used for surface treatment of mold inner holes, spraying wear-resistant and demoulding coatings, improving demoulding efficiency and mold life, and improving the quality of molding products.

Product Operate Guide     

1.Check the equipment and accessories: Confirm that the spray gun and related accessories are undamaged and secure, such as the anode nozzle, cathode electrode holder, intermediate insulator, airflow ring, and other components are tightly connected, and ensure that the cooling water channel is not blocked and shows no signs of leakage. 

2.Prepare the gas: Ensure sufficient argon or nitrogen and other working gases are available, open the cylinder valve, and adjust the pressure to the specified level required by the equipment. After replacing the gas cylinder or periodically, use soapy water to check for gas leaks and address any issues promptly. 

3.Start the cooling system: Turn on the chiller's electrical switch and power, the dual compression indicator lights should be on, and check the cooling water pressure gauge. 

4.Turn on the power: Activate the plasma power supply, touch the exhaust outlet on the upper side of the plasma power box to confirm air is being discharged. Turn on the control cabinet power, press the 'emergency stop' button, check that all gas pressure parameters meet the specified standards, and click 'Dismiss alarm'. If the alarm cannot be dismissed, click 'Fault Alarm' in the 'Menu' to view and resolve the fault.

Q1: How does the 2086 Plasma Bore Gun create a plasma arc?

A: An electric arc is generated between the anode nozzle and the cathode electrode holder to ionize the gas, thus forming a plasma arc ejection.

Q2: Why do you want the arc of the gun to be 90 degrees from the gun body?

A: This ensures that the powder is sprayed vertically onto the surface of the inner hole, making the coating more uniform and dense, thus improving the quality of the spray. 

Q3: What preparations do I need to make before using the spray gun?

A: It is necessary to check whether the equipment and accessories are in good condition and not loose, prepare the working gas and adjust the pressure, start the cooling system to ensure that the pressure is normal, turn on the power supply and check whether the parameters are up to standard, and remove possible alarm faults.

Q4: What should I do if I find an uneven coating during the spraying process?

A: It may be caused by uneven gun movement, improper spraying parameter setting, or unstable powder feeding. First check whether the moving speed of the spray gun is constant, and then check whether the parameters such as spraying current, voltage, gas flow and powder feeding volume are appropriate, and adjust them according to the actual situation.
