Φ60—Φ140 single epoxy spraying production line

1.Transmission line:

The transmission line has a total length of 43 meters, of which four are 5.5 meters x 1.2 meters, one is 8 meters x 1.2 meters, and one is 10 meters x 1.2 meters. The base and the transmission wheel brackets are all welded by 14# channel steel. 5.5 m frame 4 sets of tire,tire 8 m frame group 6, group 7 aircraft tire 10 m.

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, and 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 reducer adopts a pendulum type, and the motor is a 2.2KW variable frequency motor. There are also 3 single racks (one of which is equipped with high temperature resistant tires) for easy chasing and pipe removal.

2.Medium frequency heating :

   Medium frequency heating power supply is 350KW

3.Electrostatic spraying equipment:

 8 gun control center DK type   Each apparatus having the above automatic gun 8, a high-pressure spray gun is built, control cabinet 8 controls automatic spray gun voltage, current and gas system, and for controlling branched venturi powder pump system for the powder.

The above device contains 1 set of fluidized bed powder supply system . The size of the fluidized bed is : (L×W×H) 800×775×570 (mm) containing 8 venturi powder supply pumps.

4. Pipe system:

Dial up and down by cylinder tube pipe, with upper and lower fork tube 4, four cylinders and pneumatic and electrical control system.

5.Secondary derusting:

 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 a rotational power of 2.2kw.

6.Air compressor:

The air compressor adopts a 6- cube screw air compressor, a 1.5- cubic gas storage tank, and a 6- cubic air dryer, supporting the gas path and control part.
