Comprehensive Maintenance Guide for Powder Conveyor: Nine Step Maintenance Strategy to Ensure Efficient and Stable Operation

Powder conveyorDetailed explanation of the core steps of maintenance

Cleaning and dust prevention management

Regularly clean the conveyor belt, pulley, transmission chain, seals, internal pipelines, filters, fans, and other components of the equipment to prevent dust accumulation from causing malfunctions. For example, the screw conveyor needs to check the residual materials inside the casing daily, and the pneumatic conveying system needs to clean the dust bags and pipelines weekly.

The design of a closed conveying system can reduce dust spillage, protect the environment, and ensure the safety of operators.

Optimization of lubrication system

Sliding components such as bearings and gears require regular lubrication. Add 5 grams of lithium based grease to the bearing box of the screw conveyor every half month, and add 5 grams of grease to the suspension bearings every shift; Sodium based grease (such as ZN2) is used for high-temperature materials.

The reducer should be lubricated according to the instructions, and the hydraulic coupling should be added strictly according to the design oil amount to avoid affecting the starting performance.

Regular inspection and replacement of vulnerable parts

Focus on inspecting wear-resistant components such as conveyor belts, pulleys, transmission chains, bearings, sealing rings, solenoid valves, and filter bags. For example, the pneumatic conveying system checks the air valve and pressure gauge weekly, and calibrates the pressure gauge and safety valve monthly; Check the nylon sealing ring of the suspension bearing of the screw conveyor every shift, and perform a second maintenance after one year.

If wear or damage is found, replace it promptly to avoid equipment shutdown due to component failure.

Electrical and safety system maintenance

Regularly inspect the electrical system, sensors, instruments, alarm devices, and interlocking equipment to ensure their sensitivity and reliability. For example, the dust removal system needs to be inspected daily, with resistance values recorded and filter bag damage analyzed; Safety valves and pressure gauges need to be regularly calibrated.

Ensure sufficient lighting around the equipment and install protective barriers in narrow areas to prevent personnel from entering hazardous areas by mistake.

Operation status monitoring and adjustment

Monitor the conveying volume to avoid overloading operation; Adjust the tension of the conveyor belt to prevent slipping or breakage caused by being too loose or too tight.

The screw conveyor needs to start without load and empty the material before stopping; The pneumatic conveying system needs to monitor high pressure alarms and analyze the reasons for material changes or air pressure fluctuations.

Troubleshooting and Preventive Maintenance

Promptly handle equipment malfunctions, such as inadequate pneumatic valves, damaged pulse valve membranes, electromagnetic coil failures, etc. For example, when the pneumatic conveying system finds that the solenoid valve has no sound absorption, it is necessary to check the air supply of the compression station or replace the diaphragm.

Regularly conduct medium and major repairs, replace aging electrical components, and optimize equipment design (such as using wear-resistant lining plates and enclosed structures).

Environment and operating standards

Avoid overloading and overheating of equipment, and prevent materials from mixing into hard chunks or woven fibers that may cause blockages.

Operators must hold certificates and comply with safety regulations, such as prohibiting maintenance during operation, cutting off power after shutdown, and hanging warning signs.

After sales service and long-term maintenance

Choose a manufacturer that provides comprehensive after-sales service, including equipment installation and commissioning, operation training, troubleshooting, parts supply, and equipment upgrade and renovation. Regular follow-up visits ensure the long-term stable operation of the equipment.

Special scenario response

Pay attention to insulation and antifreeze in winter, check the cooling drainage volume and temperature; Monitor the flue gas temperature in summer to prevent damage to the filter material due to overheating.

Adjust the cleaning frequency and maintenance strategy based on different material characteristics (such as easy agglomeration and impurities), such as regularly cleaning the screen surface and cleaning brush for cylindrical initial screening.
