Φ60- Φ219 -Φ 273 steel pipe outer wall epoxy powder coating production line

First, the project content:

Φ 60- Φ 2 19 - Φ 273 steel pipe outer wall epoxy powder coating production line

Second, the process requirements

Work piece: Φ 60- Φ 273 × 12m steel pipe

Coating requirements: epoxy powder coating 300-400um

Process line speed: 3 - 7 m/min

Third, the drive line:

Transmission line length of 44 meters and comprises eight 5.0 m × 1.2 yards gear frame; bracket base and the drive wheel 14 in all channel # welding. There are also 4 single racks (one of which is equipped with high temperature resistant tires) for easy chasing and pipe removal.

The driving wheel and the driven wheel are respectively mounted on the screw adjustable plate, which facilitates the adjustment of the production size pipe. There are 4 transmission powers , all of which adopt frequency conversion speed regulation. The frequency converter adopts Hailipu frequency converter of Danfoss Technology of Denmark. The frequency conversion speed regulation makes the steel pipe transmission smooth, so that the thickness of the anti-corrosion layer is uniform. We also use a pressure tube mechanism that prevents the pipe from affecting the pipe being machined during acceleration and decoupling. The base has a height adjustment screw to facilitate horizontal adjustment of the production line.

The tires are made of 400-8 type weighted tires and connected by a universal joint drive shaft. The WPDA worm gear type reducer is used, and the motor is a 2.2KW variable frequency motor.

Fourth, medium frequency heating :

Medium frequency heating power supply is 400KW

Fifth, electrostatic spraying equipment:

8 gun control center DK type Each set of the above devices contains 6 automatic spray guns . The spray gun is built-in high pressure. The control cabinet controls the voltage, current and air circuit system of 6 automatic spray guns, and controls the powder supply system of the Venturi powder supply pump.

The above device contains 1 set of fluidized bed powder supply system . The size of the fluidized bed : (L×W×H) 800×775×570 (mm) contains 6 venturi powder supply pumps.

Sixth, the pipe system:

Dial up and down by cylinder tube pipe, with upper and lower fork tube 4, cylinder 4 and electrical control system (including a solenoid valve, the valve block, PVC pipe, control buttons, etc.).

Seventh, secondary derusting and water spray:

The wire wheel and compressed air are used to remove rust, and the surface burrs and floating ash of the steel pipe are removed to improve the adhesion of the epoxy powder. Descaling device 1 comprises a sleeve 2 and the like protection and dust discharge cover.The wire wheel has a diameter of 150mm and the rotational power is 2.0kw.

Water spray pump a centrifugal pump, a flow rate of 90m 3 / h, the motor is 5.5KW, the main spray pipe diameter is Φ 114 12m ×; spray pipe diameter of Φ 15, a total of 35, it is equipped with valves, easy to adjust The amount of water. The partition is a plastic steel window.

Eighth: air compressor:

3.0 cubic air compressor with a screw-type air compressor, a gas tank cubic 1.0, 3.0 cubic an air dryer, and a control section supporting the gas passage.
