一．传动线：

传动线全长43米，其中有4个5.5米×1.2米，一个8米×1.2米，一个10米×1.2米，底座和传动轮支架全部采用14#槽钢焊接。5.5米架4组轮胎，8米架6组轮胎，10米架7组轮胎。

主动轮和从动轮分别安装在用丝杠可调节平板上，方便了生产大小管的调整。传动动力共有4个，全部采用变频调速，变频器采用海利普变频器，变频调速使钢管传输平稳，从而使防腐层厚度均匀。我们还采用一种压管机构，能防止管道在追管和脱管加速时对正在加工管道的影响。底座有高度调整丝杠，方便生产线水平调整。  

轮胎采用400-8型加重胎，采用万向节传动轴连接。减速机采用摆针式，电机是2.2KW变频电机。还配有3个单架，（其中有一个配耐高温轮胎），方便追管和脱管。

二．中频加热:

   中频加热电源为350KW

三．静电喷涂设备：

8枪控制中心DK型 以上装置每套含自动喷枪8支，喷枪为内置高压，控制柜控制8支自动喷枪的电压、电流及气路系统，并控制支文丘里供粉泵供粉系统。

以上装置含流化床供粉系统1套,流化床外形尺寸:(L×W×H)800×775×570(mm)含8支文丘里供粉泵。

四．拨管系统：

上下管采用气缸拨管，配备上下管拨叉4个，气缸4个及电器控制系统和气路。

五．二次除锈：

      采用钢丝轮及压缩空气除锈，除去钢管表面毛刺及浮灰，提高环氧粉末的附着力。包括2次除锈装置1套和防护及排尘罩等。钢丝轮直径为150mm,转动动力为2.2kw.

 六. 空气压缩机：

空压机采用6立方螺杆式空气压缩机一台，1.5立方储气罐一个，6立方空气干燥机一台，配套气路及控制部分。

Φ 48- Φ 159 single epoxy spraying production line

Φ 60 —Φ 140 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.
