1. principle of arc spray machine

   This  high velocity  arc spraying  is a technology which uses arc to melt metal,the arc is formed by combustion in two continuous  feeding metal wire,then the melting metal is atomized by high speed airflow.Through the laval nozzle,the atomizing metal particles are accelerated to make them to exceed supersonic to spray to the workpieces to form a coating

     We have different models of high velocity arc spraying machine set series which would meet requirements for any scale of your project.  We can even do customized equipment according to your requests.  Please check the  catalogue of our arc spray machine as below:

 

 

Sanxin high velocity arc spray equipment

model No	power (KW)	gun Qty	wire diameter (mm)	gas consumption (m3/min)	application
SX-150	7	1	1.6-2	2.3	Test and research on a small amount of spraying and coating
SX-300	12	1	1.6-2	2.3	Spray zinc and aluminum ,small scale repair
SX-400	15	1	2	2.3	Zinc ,aluminum, partial repairing process
SX-500	18	1	2	2.3	Hardware repairing, small project construction
SX-600	21.6	1	2	2.3	Spray hard alloy wire, boiler construction
SX-800	28.8	2	2	4.6	Spray zinc and aluminum in big area, works automatically
SX-1000	36	2	2	4.6	project construction ,big quantity process, works automatically
SX-2000	72	4	2	9.2	Big project construction ,long time spraying project, big quantity of spraying work
SX-4000	144	8	2	18.4	Big project construction ,long time spraying project, big quantity of spraying work

      The biggest difference of the arc spray machines above  is the power ,data after code "SX "stand of  electronic current ,from 150 to 4000,then power is from 7kw to 144kw accordingly ,of course ,with different price ,you can choose the economical and practical model based on your requirement ; we can recommend you after discussing more details 

 

 some parameter of arc spray wire materials

Spray material	Wire diameter	Working current	No-load volt	Air hat diameter	Maximum spray efficiency
Zinc wire	1.2-3.0	80-210	18-30	6-8	30
Al wire	1.2-3.0	120-240	25-38	6-8	9.5
Steel wire	2.0	150-200	35-40	7-8	6
High carbon steel wire	2.0	150-220	10-44	8	5.5
Stainless steel wire	2.0	150-220	10-44	8	5.5
Zn-Al, Pb-Sn alloy wire	1.2-2.0	80-110	18-28	7

 

    Also,the velocity of micro paticles  can reach above 420m/s. The axial direction air speed can reach 600m/s. The deposition rate of coating can reach 75%

 

4. advantage of arc spray machine

1) Stable and convenient

2) High adhesive force of coating: can reach 70Mpa) 

 3) Workpiece won’t be deformed and its structure won’t be changed.(<100℃)

 4) High efficiency and wide application

 5)Spray gun for long distance(30-meter-long-cable)

6)Unnecessary to change the wearing parts frequently

7)Convenient  maintain  and repair

 

 4. Application of arc spray machine

(1)It's suitable for on-site construction, and can use all kinds of metal and metal ceramic materials, such as alloy wires, Mo, Al, Zn, red copper, copper alloy, Babbitt etc.

 

(2)It is widely applied in spraying anti-wearing and anti-rust coatings for boiler’s four kinds of tubes, coal pulverizing system (fan impeller and scroll casing), roller, dryer, axis, mould,etc.

 

(3) can spray zinc or aluminum on the metal chairs ,metal facilities in the garden ,to improve the wear resistant ,wear corrosion of them, so as to lengthen their usage life .

 

 (4) SX1000/SX2000/SX4000 even can spray big project construction ,long time spraying project 

 

(5)new application in electrolytic aluminium field about cable conductor burning-out issue
