Ukufakwa, commissioning and operation precautions of ZTE series

To ensure the stable operation and long service life of the ZTE series, correct installation, commissioning and standardized operation are crucial. The following are the key points of installation, commissioning and operation:

Installation precautions

• Site requirements: The installation site should be flat and solid, with a bearing capacity of ≥5t/m², and there should be no vibration source around to avoid affecting the operation stability of the equipment. The site should have sufficient space for operation, maintenance and material storage, with a reserved space of ≥1.5m around the equipment.
• Power supply requirements: The power supply should meet the rated power of the equipment, with a voltage fluctuation range of ≤±5%, and a dedicated circuit and leakage protector should be configured. The grounding resistance of the equipment should be ≤4Ω to ensure electrical safety.
• Water and gas supply: If the equipment is equipped with a water cooling system, the water supply pressure should be 0.2-0.4MPa, and the water quality should be clean and free of impurities to avoid blocking the cooling pipeline. The air source (if equipped with pneumatic components) should have a pressure of 0.5-0.7MPa, and be equipped with a dryer and oil-water separator to ensure the normal operation of pneumatic components.
• Installation and leveling: Use a level to adjust the level of the equipment, with a level error of ≤0.1mm/m, to ensure the coaxiality of the screw and the smooth operation of the transmission system. Fix the equipment with foundation bolts to prevent displacement during operation.

Commissioning key points

• Empty running test: Before feeding, carry out empty running test for 1-2 amahora, check the operation of the transmission system, the rotation direction of the screw, and the temperature control accuracy of each heating zone. The empty running speed should be gradually increased from low speed (100rpm) to rated speed (600rpm), and abnormal noise, vibration and temperature rise should be checked during the process.
• Material trial run: Use clean general plastic particles (such as PP) for trial run, start feeding at low speed, and gradually increase the feeding amount and screw speed while observing the melting state of the material, extrusion pressure and product quality. Adjust the temperature of each heating zone according to the melting condition of the material to ensure full melting and no decomposition of the material.
• Parameter optimization: According to the trial run results, optimize the screw speed, feeding speed, temperature and other parameters to find the best process parameters for the production of specific materials, and record them for daily operation reference.

Operation precautions

• Pre-operation inspection: Before starting the machine every day, check the oil level of the gearbox, the tightness of the electrical connections, the cleanliness of the feeding hopper, and the operation of the cooling system to ensure that all parts are in normal condition.
• Material requirements: The processed materials should be clean and free of metal impurities to avoid damaging the screw and barrel. For hygroscopic materials (njenge ABS, PA), they should be fully dried before processing to avoid bubbles and other defects in the product.
• Operation process: The machine should be started and stopped in accordance with the operating procedures. It is strictly forbidden to start the machine with material in the barrel, and it is strictly forbidden to stop the machine suddenly during operation (except for emergency situations). When changing materials, the barrel and screw should be cleaned to avoid material mixing and affecting product quality.
• Daily maintenance: Clean the equipment surface and feeding hopper after daily operation, check the wear of the screw and barrel regularly, and lubricate the moving parts according to the maintenance manual to extend the service life of the equipment.
• Emergency treatment: In case of equipment failure (such as overload, over-temperature, abnormal noise) ngesikhathi sokusebenza, stop the machine immediately, cut off the power supply, and contact the after-sales service personnel for treatment. It is strictly forbidden to disassemble the equipment without authorization to avoid expanding the fault.
