Component	Characteristic	Parameter
D-3000 Powder feeder	The powder feeder is a high precision powder feeding mechanism which outputs via metering panel, uses patented feeding valve, with powder evenly output, having higher precision compared with the conveying modes of scraper type, screw and vibration, etc.;    Adopting small-flow nitrogen or argon gas as feeding gas, which, together with powder that arrives at powder outlet with rotation of feeding panel on the bottom, enters the spray gun, to save more gas than traditional mesohigh powder feeder.    Compared with the traditional double barrel type powder feeder, the metering disc type powder feeder is more fine and the powder particle size range is wider.

Characteristics and advantages of HV-80-JP supersonic flame spraying system

1, Solid cabinet design, fuel flow control area, pressure display area, electronic control area are modular layout, panel clear and easy to operate.
2. All imported valves, pressure switches, flow switches and sensors from Europe and America are of the same quality as those from Europe and America
3, The use of Japanese mitsubishi high-performance PLC control, after ignition automatically maintain oxygen and fuel, carrier gas flow output.
4. All the internal fuel, oxygen, carrier gas and cooling water connected on the equipment have the detection function to ensure that all preparation processes can be fully tested before ignition.
5. Monitor the running status of the equipment in real time. Once any part is found to be operating beyond the safe range, the whole system will stop sharply, send an alarm and provide fault information.
6. The equipment starts and stops automatically under the control of PLC, which reduces the possibility of operator's misoperation.
7. Communication interface is set up inside the equipment to control the operation of peripheral devices.
8. Signal shielding measures are adopted to protect peripheral devices from electromagnetic interference during high frequency arc ignition.
 

I. Performance indexes of supersonic flame spraying tungsten carbide
Hardness up to: HRC70~80
Binding strength: ≥ 90Mpa
High temperature resistance: 1200ºC or more
Surface roughness: Ra0.2
Strong corrosion resistance, not easy to deform
Coating thickness: 0.04mm~0.1mm
Straight linearity: 0.015mm-1000mm
Two, supersonic flame spraying tungsten carbide in the application of corrugated roller
1, thermal spraying tungsten carbide in the application of corrugated roller
A. Spraying tungsten carbide by new corrugated roller
B. Reforming old corrugated roller into tungsten carbide corrugated roller
The coating thickness of the new tungsten carbide corrugated roller is 0.05-0.1mm. When the coating is reduced for a long time and cannot be produced, we will remove the residual tungsten carbide and repair it for you. The diameter of the corrugated roller is almost unchanged.
2. Adding process of tungsten carbide corrugated roll
Tungsten carbide corrugated roll process, unlike traditional corrugated roller, before the first matrix hardness, heat treatment before spraying the shape accuracy is higher, must be finished on the fully automatic CNC grinding, followed by spraying technology is the key, to ensure the hardness of tungsten carbide binding force and the quality of the polishing processing, after the hard part is after spraying, polishing technology, processing of the corrugated roller is different from general workpiece, The unique tooth profile and the high surface hardness (such as diamond) of tungsten carbide are simply not possible with conventional grinding wheels.
→ grinding teeth → (medium frequency quenching) → sandblasting → preheating → backing → spraying tungsten carbide (thickness of 0.05 ~ 0.06 → polishing - life 20 ~ 50 million meters;
3, the advantages of tungsten carbide corrugated roller
A. The service life of tungsten carbide corrugated roller is 3 ~ 6 times more durable than that of ordinary corrugated roller.
B. Generally, the tooth height of the corrugated roller changes greatly, and the quality of the cardboard is unstable. The gap between the core paper and the cots should be 0.1mm ~ 0.2mm when the new roll is rolled. The change of tooth height of tungsten carbide corrugated roller is small and long, and the quality of paper pulling is straight and stable.
C. Generally, the middle of the corrugated roller is worn too much and becomes concave. It will not be able to produce wide-width cardboard and waste paper, because both ends will be crushed or the middle will not be pasted (degumming and foaming). At this time, you have to grind both ends of the roller to walk wide-width cardboard and maintain the life of the corrugated roller. Because of the wear-resistant tungsten carbide corrugated roll, there is no narrow paper and then go wide paper problems.
D, the general corrugated roller because of fast wear, so the original design of high tooth (high corrugated rate), to ensure the life; Because of wear resistance, the tungsten carbide corrugated roller is designed from the beginning with low teeth and high (low corrugated rate) and long service life.
E, the general corrugated roller can not use V-shaped corrugated, because if the corrugated top is small, it will soon be worn out, the cardboard will be more and more soft; The tungsten carbide corrugated roll does not have this problem because of its wear resistance.
F, the tooth top of the general corrugated roller wear fast and much, after repair, the diameter is much smaller; The diameter of the tungsten carbide corrugated roller is almost unchanged after repair because of wear-resisting and less wear. And the most important thing is: tungsten carbide corrugated roller in the whole roll life, its corrugated height is almost the same.
