The operation and maintenance of HDPE heat fusion butt welding machine involves many aspects, aiming to ensure the operation safety, improve the welding quality and prolong the service life of the equipment. The following is a detailed description of the operating procedures, precautions and routine maintenance of HDPE heat fusion butt welding machine:
Safe Operation
Personal Protection: Wear appropriate personal protective equipment, such as protective gloves, goggles and protective shoes before operation to avoid accidental injury.
Electrical Safety: Ensure that the power supply in the work area meets safety standards, is well grounded, and does not use damaged power cords or plugs.
Cleaning operation: Ensure that the surface of the PE pipe is clean and free of oil and water before operation, and use cleaners or removers to clean it to ensure the best bonding effect.
Hot melt operation: Place the pipe on the working platform of the machine and adjust the temperature and pressure to make the pipe reach the molten state. Ensure sufficient cooling time after the operation is completed to prevent burns.
Handling of molten material: Use special tools to handle the molten PE material, avoid direct manual operation to prevent burns.
Maintenance Method
Preparation before use: Check the heating plate, if the coating is damaged it should be replaced or repaired. Residues of polythene on the surface of the heating plate can only be removed with wooden tools, oil grease etc. must be treated with clean cotton cloth and alcohol.
Heat fusion welding operation: This includes the steps of milling the welding surface, measuring and recording the drag pressure, placing the heating plate, and adjusting the welding pressure. When the height of the circumferential crimp protrusion at the welding place on both sides of the heating plate reaches the specified value, reduce the pressure to the drag pressure, start the heat-absorbing timing, and then quickly raise the pressure to the welding pressure at an even rate.
Operation precautions: the operator must be specially trained and qualified by examination. Note that the electrical appliances, control part is not waterproof, in case of rainy day construction should take protective measures. Appropriate protective measures must be taken when welding below zero degrees. Ensure that the welding surface is clean and dry to ensure the continuity of the welding process and adequate natural cooling after welding is completed.
By following these operation and maintenance guidelines, you can improve the service life and welding results of your HDPE heat fusion butt welder while ensuring safe operation.
