Insulated bearing
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

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. |
