The project content:
Φ 60- Φ 2 19 steel pipe outer wall epoxy powder coating production line
Second, the process requirements
Work piece: Φ 60- Φ 2 19 × 12 m steel pipe
Coating requirements: epoxy powder coating 300-400um
Process line speed: 3- 8 m/min
Multi-four, tube shot blasting machine
This machine is specially designed for the shot blasting machine on the outer wall of steel pipe to remove the scale on the surface and increase the surface area to increase the coating adhesion.
Transmission line length of 35 m, comprising four 9.0 m × 1.2 yards gear frame; bracket base and the drive wheel 14 in all channel # welding. 4 also has a single carrier, (which has a high temperature with the tire), 2.2KW inverter motor.
Electrostatic spraying equipment:
1 , 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 pneumatic system of 6 automatic spray guns, and controls the powder supply system of the Venturi powder supply pump. The above device contains one 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.

Complete configuration list:
Model 787 2.7
Circuit breaker (Delixi)
Ø12 tube, inner diameter Ø190
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.).
Secondary descaling 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 therotational 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 of Φ 114 × 9 m; diameter of the spray pipe Φ 15, a total of three 0, are equipped with valves, Easy to adjust the amount of water. The partition is a plastic steel window.
3 cubic air compressor with a screw-type air compressor, a 1.0 cubic tank, 3 a cubic air dryer, and a control section supporting the gas passage.
Eleven, manufacture and installation period:
The production line is manufactured for 25 working days and the installation period is 10 working days.
