SX-80 plasma sprayed bearing insulation coating      Spray finish       Bearing passed 15000V/ 5000V insulation test


SX-80 plasma sprayed bearing insulation coating bearing passed 15000V/ 5000V insulation test

 

1---- bearing insulation adopts SX-80 plasma spraying process:

 

Sand and rust removal roughness -- spraying alumina powder coating ---- to complete the coating thickness -- test insulation function up to standard.

 

2---- The bearing surface is sprayed with aluminum oxide coating with a thickness of about 100-300 microns to make the bearing have insulation properties.

 

3---- test Pass the 1500V/5000V test function

 

4---- The thickness of the coating determines the strength of the voltage resistance, which can resist electrical flameouts below 1000 volts.

 

5--plasma equipment  SX-80 spray insulated bearings produced by Guangzhou Sanxin passed 1500V/5000vde high voltage test respectively.

 

 

 

The difference between insulated bearings and ordinary bearings is mainly reflected in the following aspects:

 

1. Different materials: insulated bearings are usually made of non-metallic materials, such as ceramics, organic materials, etc., while ordinary bearings are made of metal materials 1 2.

 

2. The difference in structure: insulated bearings are usually composed of inner and outer rings, cages and bearing balls, etc., while ordinary bearings are composed of inner and outer rings, rolling bodies and cages.

 

3. Different uses: insulated bearings are mainly used in electrical equipment and other fields, such as wind turbines, motors, etc., while ordinary bearings are widely used in general machinery, tool machines, automobiles, motorcycles and other industries.

 

In addition, insulated bearings have higher electrical insulation during use, which can isolate the current in electrical equipment and improve the efficiency and stability of electrical equipment

SX-80 Plasma spraying equipment configuration

 (using gas: argon and hydrogen) (water and electricity)

MF Sx-80 plasma equipment using energy: power supply + argon + hydrogen (suitable for SG-100 advanced plasma spray gun)

1.  Plasma arc is made of electric power supply  (Make up the arc)

2.  A small amount of hydrogen gas is mainly used to adjust the voltage on the device  (Hydrogen for voltage regulation)

3.  Argon is used to protect spraying ceramic powder, prevent oxidation protection. (Argon gas for protecting ceramic powders)

 powder feeder

1.PLC and touch   screen are used to set parameters to precisely control powder feeding   accuracy and speed.

2The system consists of two sets of independent   powder feeding devices. The capacity of the large tank is 20 liters, and the   speed of the scraper-type powder feeding is 150 g/min. The small tank adopts   the drum-type powder feeding device, which is suitable for feeding various   ultra-fine powder and hard-to-deliver powder mixtures.

3Fully enclosed plastic-steel chassis, free from   environmental disturbance such as temperature and humidity, transparent glass   door, powder feeding state at a glance.

Powder vibration   device, powder tank heating device and weighing device can be selected

SG-100

 spray gun

 

 

The SG100 can be   applied to any type of coating available today, from highly dense,   wear-resistant carbide coatings to thermal barrier coatings with controlled   porosity. The SG100 can be used at the same time to achieve higher spray   speeds and to mix different materials in equal ion beams. The external feed   mouth can replace the internal feed mouth, and the internal and external feed   mouth can also be used in combination.

We can offer   customer SG100 spray gun, using argon or nitrogen as main gas, hydrogen as   secondary gas. The working current of spray gun: 100-800A. The working   voltage: Ar+H2: 50-75V, N2+H2: 50-80V. We provide the following spray gun   accessories for  our customer: spray nozzle, powder and cooling air   jetting shelf, water-cooled cable, electrode tip, insulator,   sealing ring, and other special tools.

 transfer box

 

The transfer   center of the spraying system connects the power supply, control cabinet,   heat exchanger and spray gun together. The box is equipped with high frequency   ignition, water, gas alarm device. Box is movable, water cable length is 5m   (standard type)

Also known   as chiller or chiller, it is mainly used to cool the distilled water cooled   by the spray gun through the refrigeration principle of heat exchange to   obtain a lower water temperature of the cooled distilled water circulation   into the spray gun, so that the spray gun to obtain effective cooling, to   achieve the spray gun is always in the right working temperature and nozzle   life extension purpose. Double compressor drive to reduce the size of the   whole machine, increase your space;
