F1500 plasma suspension powder feeder

1. Aerospace and gas turbine manufacturing

In the preparation of thermal barrier coatings for aero engines, the powder feeder can stably transport yttrium-stabilized zirconia suspension, and form a dense high-temperature resistant coating through plasma spraying, which significantly improves the life of turbine blades. Its dual-chamber reservoir design avoids sedimentation of high-viscosity ceramic suspensions and ensures a <±3% deviation in coating uniformity during continuous spraying, meeting the precision requirements of aerospace components.

2. New energy equipment and chemical anti-corrosion

In the field of wind power equipment, the powder feeder supports NiCrAl suspension spraying, which is used to strengthen the surface of the bearing housing, and the wear resistance is 3 times higher than that of the traditional process, which can adapt to the high salt spray environment of offshore wind power. In the protection of the inner wall of the chemical reactor, the tungsten carbide-cobalt cermet suspension is precisely conveyed through the powder feeder to form a corrosion-resistant coating with a porosity of <1.5%, which is better than the electroplating process in terms of strong acid corrosion resistance, and the maintenance interval is extended to more than 5 years.

3. Semiconductor and electronics industry

For semiconductor etching equipment, the powder feeder can spray a suspension of yttrium oxide nano to form a low-roughness coating on the inner wall of the plasma etching cavity, effectively inhibiting metal contamination and extending the service life of the equipment. Its high-pressure piston pump precisely controls the powder feed rate to meet the semiconductor industry's stringent requirements for coating thickness tolerances of ±5 μm.

4. Mechanical remanufacturing and surface engineering

In the field of hydraulic pillar repair, the powder feeder is combined with a supersonic spray gun to realize the remanufacturing of cemented carbide coating, and the wear resistance of the piston rod of the repaired hydraulic cylinder is restored to 90% of that of new products, and the cost is only 30% of that of replacing new products. For consumable parts such as rolls and drawing wheels, the powder feeder supports nano WC-Co suspension spraying, which extends the life of wear parts by 2-3 times, and adapts to the continuous production needs of steel, paper and other industries.

5. Precision mold and automobile manufacturing

In automotive mold surface treatment, the powder feeder can convey Cr₃C₂-NiCr cermet suspension, and the pulse feed mode can achieve uniform coverage of complex curved surfaces, reducing the frequency of maintenance of injection molds. For engine components, the powder feeder supports nanostructured Al₂O₃ suspension spraying, which forms a thick anti-friction coating on the piston ring surface, reducing the coefficient of friction to 0.08 and improving fuel economy.

6. Advanced Materials and Nanotechnology

In the preparation of nano coatings, the powder feeder ensures the uniformity of suspended particles through ultrasonic dispersion pretreatment, and with plasma spraying, it can form an ultra-thin nanostructure coating with a thickness of 25-50μm and a porosity of <1%, which is suitable for high-end applications such as fuel cell electrodes and sensor sensitive layers. Its magnetically coupled stirrer effectively disperses highly viscous ceramic suspensions.

7. Environmental protection equipment and special coatings

In the protection of high-temperature components of the waste incinerator, the powder feeder supports MoSi₂-SiC composite ceramic suspension spraying to form a coating resistant to high-temperature oxidation at 1400°C, and the thermal shock resistance is 5 times higher than that of traditional coatings, significantly extending the equipment replacement cycle. For wastewater treatment equipment, the powder feeder can be sprayed with a superhydrophobic suspension to form an antifouling coating on the inner wall of the pipe, reducing bio-attachment and clogging

Product Operate Guide     

Boot sequence

Turn on the cooling system→ enter the carrier gas→ start the stirring motor→ start the piston pump→ and start the power supply of the spray gun synchronously.

Process monitoring

Pressure monitoring: The outlet pressure of the piston pump should be stable at 1.5-2.5MPa, if it exceeds 3MPa, it needs to be stopped to check the pipeline blockage.

Temperature monitoring: The temperature rise of the cooling water should be ≤ 10°C/hour, and the cooling flow rate should be increased when it is exceeded.

Visual inspection: Observe the flow of the suspension through the transparent window of the reservoir to avoid precipitation or bubbles.

Shutdown steps

Turn off the gun power→ stop the piston pump→ turn off the carrier gas→ drain the reservoir→ flush the line with deionized water for 5-10 minutes → turn off the cooling system.
