Induction heating furnace oil pipe end thickening production line use environment

1.Environment for the thickened production line of tubing ends

① indoor installation, the equipment is well grounded, the color of the ground wire is significantly different from the control wire (the color of the ground wire is yellow), its cross-sectional area is> 4mm2, and the grounding resistance is not greater than 4Ω;

② The altitude does not exceed 1000 meters, otherwise the rating should be reduced;

③ The ambient temperature does not exceed + 40 ° C and not less than -10 ° C;

④ Relative air humidity is not more than 85%;

⑤ No severe vibration, no conductive dust, no corrosive gas and explosive gas;

⑥The installation inclination is not more than 5 degrees;

⑦ Install in a well-ventilated place.

2. Grid requirements for thickened tubing end production lines

1) The power distribution capacity of 180KW intermediate frequency power supply is not less than 225KVA. 220KW intermediate frequency power distribution capacity is not less than 275KVA

2) The grid voltage should be a sine wave, and the harmonic distortion is not greater than 5%.

3) Unbalance between three-phase voltage should be less than ± 5%

4) The input voltage of the power grid is AC 380V, and the continuous fluctuation range of the power grid voltage does not exceed

± 10%, the frequency variation of the power grid should not exceed ± 2% (that is, it should be between 49 ~ 51HZ).

5) 180KW, 220KW IF power input cable adopts three-phase four-wire system, and the specifications of the input cable are copper core 240mm2 or 120mm2 × 2.

3. Main technical indicators of water cooling system

Intermediate frequency power supplies, water-cooled cables, capacitor cabinets, induction heating furnaces, etc. are cooled by two FL-500 air-water exchangers.

4. The main technical indicators of the sensor drive system

1) Sensor specifications:

Sensor # 1: Inner diameter ф100mm, suitable for typical tubing specifications ф60.3 ~ ф73.03mm.

Sensor # 2: Inner diameter ф120mm, suitable for typical tubing specifications ф88.9mm

2) Sensor adjustment:

X-axis direction (left and right): ± 10mm

Z axis direction (up and down): ± 25mm

3) Sensor length: 500mm-650mm
