Process requirements of sucker rod epoxy spraying production line

Work piece: Φ20-Φ32 × 10m

Coating requirements: epoxy powder coating 400-500um

Process line speed: 3-4m/ min

Coating line

Transmission line length of40m, containing eight 4.0 m × 0.8 yards gear frame; bracket base and the drive wheel 10 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.

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 drive wheel uses pneumatic tires (due to the small light weight of the work-piece, the deformation ability of the pneumatic tire is strong), and the drive shaft is connected. The reducer uses a pendulum type reducer. The coating line has a total length of 40meters.
