What should be paid attention to when installing Solar PV Round Wire Machine

      The installation of Solar PV Round Wire Machine (used for photovoltaic ribbon/round wire processing) involves the following five steps: basic leveling, precise leveling, alignment, electrical and grounding safety, clean environment, and no vibration during trial run. The steps are "preparation → positioning → leveling → piping and wiring → debugging". The following points will be explained clearly (refer to GB51206-2016 Photovoltaic Equipment Installation Specification).

1、 Preparation before installation (key to prevent rework)

Venue and Foundation

      Ground bearing capacity ≥ equipment weight × 1.5, concrete strength ≥ C30, surface flatness ≤ 2mm/m.

      Reserve an operating space of ≥ 0.8m in length and width for the reserved equipment, with a clearance of ≥ 2.2m above to avoid interference from beams, columns, or pipelines.

      Pre embedded steel plates or anchor bolts for the foundation, with a positional deviation of ≤± 3mm and consistent elevation.

Equipment unboxing and inspection

      Check the model, accessories, and instructions, and ensure that there is no deformation or collision on the appearance, and that the spindle/pay off reel is not damaged.

      Precision components (guide wheels, molds, tension sensors) should be stored separately to prevent dust and moisture.

Tools and Environment

      Essential: Level gauge (0.02mm/m), torque wrench, dial gauge, wire clamp, insulation shake gauge.

      Environment: Clean and dust-free (humidity 40% -60%), away from vibration sources (punching machines/fans), temperature 18-28 ℃.

2、 Equipment positioning and fixation (accuracy determines product quality)

Positioning and rough adjustment

      Place the forklift/crane steadily in place, aligning the body with the centerline of the foundation, with a deviation of ≤± 2mm.

      Pre tighten the anchor bolts, leave a slight adjustment margin, and prohibit strong pulling or prying.

Precise leveling (of utmost importance)

      Vertical/horizontal levelness ≤ 0.02mm/m (measure the base/spindle end face of the machine body with a precision level).

      The multi-stage fuselage needs to be aligned with a seam height difference of ≤ 0.03mm to prevent vibration during operation.

      Stainless steel thin washers shall be used for the pad iron, with no more than 3 pieces per location. The bolts shall be tightened symmetrically in stages, and the torque shall comply with the instructions.

Installation of pay off/collection rack

      The center of the unwinding/rewinding reel should be strictly aligned with the main guide wheel/mold, with a coaxiality of ≤ 0.5mm.

      The verticality of the bracket should be ≤ 1mm/m, firmly fixed to prevent high-speed operation and shaking.

3、 Electrical and Control Installation (Safety First)

Power supply and wiring

      Voltage/frequency matching (e.g. 380V/50Hz), independent circuit, equipped with leakage protector (30mA).

      Fire retardant PV1-F photovoltaic special wire for cables, threaded through metal cable trays/conduits, fixed at intervals of 0.6-1m to avoid wear and tear.

      The wiring terminals should be firmly crimped, the insulation should be properly wrapped, and virtual connections are strictly prohibited; The positive and negative poles on the DC side are verified to be correct.

Grounding and lightning protection

      The body, motor, electrical control cabinet, and pay off rack are all reliably grounded with a grounding resistance of ≤ 4 Ω.

      Grounding with a yellow green line of ≥ 16mm ², single point grounding to avoid circulating current; Connect to the lightning protection network in the factory area.

Control and Signal

      Touch screen/PLC wiring shielding layer single ended grounding, away from power lines (spacing ≥ 0.5m), to prevent electromagnetic interference.

      The emergency stop button is eye-catching and easy to touch, with reliable action; The wiring of the limit/tension sensor is secure and the signal is normal.

4、 Mechanical and auxiliary system installation (leak proof and vibration proof)

Transmission and guiding components

      The spindle/bearing is clean and free of impurities, and special lubricating grease is added according to the instructions. The oil level is normal.

      The guide wheel/wire feeder is smooth and free of burrs, and rotates flexibly; The mold installation is coaxial and the tightening torque meets the standard.

      The tension of the belt/chain is moderate and there is no deviation; The gear mesh clearance is normal and there is no abnormal noise.

Cooling and lubrication

      The cooling water pipeline has no leakage, the water pressure/flow rate meets the requirements, and the water quality is clean and anti scaling.

      The lubrication system has a smooth oil circuit, no leaks, and the oil model/level is correct.

tension control

      The tension sensor is installed horizontally, with the direction of force consistent with the direction of the wire, and calibrated accurately.

      The braking/winding tension is adjusted smoothly, without any sudden tightening or loosening, to prevent the wire from becoming thin or broken.

5、 Debugging and trial operation (required before delivery)

No load debugging

      Manual turning without jamming, running without load for 30 minutes: no abnormal vibration/noise, temperature rise ≤ 40 ℃, bearing temperature ≤ 70 ℃.

      The movement of each axis is stable, the limit/emergency stop is effective, and the tension control response is normal.

Load test run

      Use waste wire to run at low speed, check the direction of the wire, wear of the guide wheel, and heating of the mold, and ensure there are no scratches or broken wires.

      Gradually increase the speed to the rated speed and run continuously for 2 hours: the parameters are stable, the dimensional accuracy meets the standard, and there are no abnormalities.

Acceptance and recording

      Refer to GB51206-2016 and the instruction manual for acceptance, fill in installation/commissioning records, and archive for future reference.
