**3-CERTIFICATE:** CE **4-STORAGE CONDITION:** 1) Store the compressor in a dry and well-ventilated area. 2) Avoid tilting, inverting, or colliding during storage, transportation, and installation. 3) Do not remove the rubber plugs from the discharge tube before installation to prevent contamination and moisture. During installation, remove the discharge tube plug first, then the process tube plug, and finally the suction tube plug. Complete the installation within 10 minutes after removing the plugs. 4) Accessories such as starters and thermal protection devices are not included in the compressor at delivery but are packed separately. Make sure to select the correct models for these components. --- This version improves clarity, adds a bit more context, and enhances readability while maintaining all key technical details.

Light Pole Productions Line

Light Pole Shut & Welding Machine is mainly for making light pole.street pole.traffic pole.Flagpoles etc. The cross section of the street light pole has various shapes such as:round, octagon, dodecagon(twelve sides) and so on.Viewed from the length of the rod, it is generally tapered. We often named these poles: tapered light pole,tapered street pole .. etc. The conical traffic post is widely used in the road, the taper flagpoles are widely used in the square, citizen garden... etc.

The production of street light poles includes many processes: the cutting of trapezoidal plates, the bending of street light poles, the stitching of bending openings, the welding of bending openings, the deformation correction of street lighting poles, surface grinding, welding of ribs, surface galvanizing.

Production process of street lamp poles
1. Cutting and cutting (rolling shearing machine)
1. Before cutting, firstly adjust the inclination of the cutting machine to match the required longitudinal scissors.
2. Determine the position of the steel plate to ensure the maximum size of the remaining material, so that the remaining material can be used.
2. Bending
Bending is the most critical process in the production of light poles. The quality of the bending directly affects the quality of the light pole and cannot be repaired after bending. The specific attention is as follows:
1. First remove the slag of the sheet, check the length, width and straightness of the sheet, the non-straightness is less than or equal to 1/1000, if the non-straightness meets the requirements, make corrections, especially the polygonal rod must ensure the non-straightness.
2.Increase the bending depth of the bending machine and determine the position of the sheet.
3.Correctly draw the line on the sheet material section, the error is ≤ soil 1mm. Correct alignment, correct bending, so that the pipe seam is minimized, and the height of the two sides is not more than 5mm.

3. Welding:Straight seam welding is performed on the bent pipe seam during welding. Since the welding is automatic submerged arc/CO2 gas shielded welding, attention should be paid to adjusting the welding position during welding to ensure the straightness of the welding seam.

4. Repair and polish:Repair and grinding is to repair the defective pipe after automatic welding. The repairers should check one by one, and repair the defective places. After the repair welding is completed, they will be repaired. The repaired joints are basically the same as the automatic welding seam.
5. Plastic surgery:The shaping process includes the straightening of the light pole and the full circle and polygonal diagonal dimensions of the two ends of the pole. The general tolerance is 1t; ± 2mm. The straightness error of the return rod does not exceed: ≤1.5/1000.
6, Milling bottom face:The flushing process is to flatten both ends of the bent tube blank to ensure that the nozzle is perpendicular to the center line, and there is no angle and height unevenness.
7. Install the bottom plate:The key to spot welding the bottom flange and the rib plate is to ensure that the bottom flange is perpendicular to the straight center line of the lamp, the rib plate is perpendicular to the bottom flange, and is parallel to the straight bus bar of the lamp.
8. Weld bottom flange:Welding requirements refer to the national standard welding process to ensure the welding quality. The welding seam should be neat and beautiful.
