C-1000DA Powder Feeder

The system is equipped with 2 powder feeding cylinders, two can be used at the same time, can also be used separately, the powder feeder is controlled by touch screen, and the powder gas flow is accurately controlled by the mass flow controller imported from abroad, which ensures the stability of the gas flow;

The C-1000DA powder feeder is a high-precision powder feeding mechanism with scraper output, which is suitable for the precise conveying of powder in thermal spraying and laser melting equipment. The internal structure of the powder feeder is provided with a unique purging self-cleaning structure, which can effectively self-clean and prevent fine powder from being mixed in the parts of the equipment, which has a very significant effect on the blockage of fine powder powder, and the coarse powder is not easy to block, and the powder feeder is maintenance-free and worry-free. Using a small flow of nitrogen or argon as the powder feeding gas, the powder reaches the powder outlet with the rotation of the bottom powder feeding tray, and enters the spray gun together with the powder feeding gas, saving more gas than the traditional medium and high pressure powder feeder.

At the same time, the powder feeder can make the mouth of the powder drum turn downward, and complete the powder pouring and cleaning work in three seconds, which is now widely used in thermal spraying devices and has become one of the indispensable and important devices in the thermal spraying industry.

The C-1000DA powder feeder is mainly composed of the main body of the powder feeder, the bracket and the base. The main structure is composed of tank, box, electrical control, rotary drive, etc., and the tank is composed of turntable, powder valve, carrier gas assembly, cylinder head and other components.

Under the action of the turntable, the powder fills the groove of the disc, and is driven by the counterclockwise rotation of the continuously variable speed motor, and rotates to the blanking port with the high-precision disk. Under the pressure of the carrier gas in the tank and the negative pressure generated by the powder feeding valve, the carrier gas is successively fed into the spray gun system to complete the thermal spraying process. The amount of spraying is controlled by a stepless speed regulating motor. Accurate powder feed greatly improves the uniformity of the coating and the quality of the spray.

Technical parameters of C-1000DA powder feeder

• The powder feeder is a high-precision powder feeding mechanism with turntable scraper output, and the powder output is uniform.

• The powder feeder is equipped with a touch screen and an imported brand mass flow controller, which makes the carrier gas flow conveying more accurate.

• Using small flow of nitrogen or argon as the powder feeding gas, the powder reaches the powder outlet with the rotation of the bottom powder feeding tray, and enters the spray gun together with the powder feeding gas, which saves more gas than the traditional medium and high pressure powder feeder.

• Wide range of powder particle sizes.

• It adopts the latest inclined structure in the world, which is convenient for cleaning the powder, and it only takes 3 seconds to turn the barrel body and pour out the powder

1. Machinery manufacturing: For the inner holes of hydraulic cylinders, oil cylinders and other parts, coatings with excellent wear resistance and anti-corrosion characteristics are applied to effectively extend their service life and reduce capital investment in maintenance.

2. Automobile industry: It is used in the inner bore area of the cylinder barrel and piston ring groove of the automobile engine to help improve the overall performance and operational reliability, reduce the wear and leakage risk between components, and help fuel economy to a new height.

3. Aerospace: Focusing on the mortise and groove of aero engine turbine blades, the inner hole of the casing, etc., the spraying process is carried out to accurately meet the strict requirements of high performance and high stability in this field.

4. Mold manufacturing: Carry out strengthening and repair operations for the inner hole of the mold, vigorously improve its wear resistance, smoothness of demoulding and the ability to resist thermal fatigue, and promote the use time and manufacturing efficiency of the mold.

5. Power industry: Put on a protective "coat" for the inner hole of generator rotor journal and steam turbine blade, firmly strengthen its strength of wear resistance and erosion resistance, and escort the smooth and continuous operation of equipment.

Product Operate Guide     

1. Check whether the appearance of the powder feeder is damaged and whether the parts are firmly connected.

2. Make sure the power supply meets the requirements, use 220VAC±10%, 50Hz AC, and ensure good grounding.

3. Prepare the required powder material, ensure that the particle size of the powder is in the range of 20 - 200μm, and that it is dry and free of impurities.

4. Choose the appropriate powder reservoir according to the characteristics of the powder, such as the left powder with stirring motor can be used for ceramic powder with poor fluidity, and the right powder without stirring motor can be used for metal powder with good fluidity.

5. Install the remote control plug on the remote control socket under the back of the powder feeder and screw it tight.

Q1: What is the accuracy of the powder feeder?

A: The powder feeding volume is continuously adjustable, and the repeatability can reach ±2%, which can accurately meet the requirements of different thermal spraying processes for powder delivery capacity.

Q2: What is the particle size range of the powder it can convey?

A: This powder feeder can accurately and stably convey all kinds of thermal spray powders with particle sizes from 20 to 200μm, including metals, ceramics and other powder materials.

Q3: Is the operation of the powder feeder complicated?

A: Not complicated. The equipment is easy to operate, and there are power switches, status selection knobs, powder feeding speed adjustment knobs, etc. on the panel, which can be easily controlled locally. It can also be connected to the remote control equipment through the remote control socket to realize remote operation, reduce the difficulty of the operator's work and improve work efficiency.

Q4: How to adjust the powder feeding speed?

A: In the local control mode, the speed of the powder feeding tray can be changed by adjusting the powder feeding speed adjustment knob on the powder feeder panel, so as to realize the adjustment of the powder feeding speed. In remote control mode, the powder feeding speed can be adjusted by controlling an external signal source.
