Xin Beifang Pneumatic Conveying Pump maintenance is crucial to ensure its normal operation and extend its service life. Below are some key maintenance points:

I. Daily Maintenance

1. Visual Inspection

(1) Before and after equipment operation each day, inspect the pump’s exterior for any damage, such as cracks or deformations in the pump body, and check whether bolts at connection points are loose.

(2) Inspect the paint coating for integrity. If peeling is found, repair it promptly to prevent rusting of metal parts.

2. Valve Inspection

(1) Check the sealing performance of valves such as the feed valve, discharge valve, and intake valve. Look for signs of material leakage around the valves. If leakage is detected, replace the valve seals promptly.

(2) Ensure that the opening and closing actions of the valves are flexible. Regularly clean debris and accumulated dust on the valves to prevent jamming. Manually operate the valves to check their flexibility. If significant resistance is felt, cleaning or repair is necessary.

3. Instrument Inspection

(1) Check the display of instruments such as pressure sensors and level gauges for normal readings. Pressure sensor readings should be within a reasonable range. Abnormal fluctuations or deviations may indicate blockages or other issues inside the pump.

(2) The level gauge should accurately reflect the actual material level in the pump. Regularly clean the probe of the level gauge to avoid inaccurate measurements due to dust accumulation.

4. Fluidization Device Inspection

(1) Check whether the fluidization device is functioning properly. The fluidization device is a key component for ensuring smooth material fluidization and conveyance. Inspect the fluidization plate for blockages or damage.

(2) Issues with the fluidization device may prevent proper material fluidization, affecting conveyance efficiency. The operational status of the fluidization device can be preliminarily assessed by observing the material’s fluidization state and conveyance performance.

II. Periodic Maintenance (Weekly / Monthly / Quarterly, etc.)

1. Internal Cleaning

(1) Regularly (e.g., monthly) clean the interior of the pump to remove material residues adhering to the inner walls, fluidization device, and inside the valves. These residues may gradually accumulate, reducing the pump’s effective volume, impairing fluidization, or causing valve leakage.

(2) Before cleaning, close relevant valves and power sources to ensure safe operation. Use appropriate tools, such as shovels and brushes, to remove materials, and then blow-clean the interior with compressed air.

2. Lubrication Maintenance

(1) Regularly (e.g., quarterly) lubricate moving parts of the pump, such as valve shafts and lead screws. Use suitable lubricants and follow the equipment manufacturer’s recommendations to ensure smooth operation and reduce wear.

(2) Simultaneously, check lubrication points for leaks. If lubricant leakage is detected, address it promptly to avoid contaminating materials or affecting equipment performance.

3. Electrical System Inspection

(1) Regularly (e.g., monthly) inspect the pump’s electrical system, including wires, connectors, and control cabinets. Check for signs of wire damage or aging, loose connections, and ensure electrical components in the control cabinet are functioning properly.

(2) Ensure the electrical system is well-grounded to prevent electric shock hazards. Use tools like insulation resistance testers to check electrical insulation performance, ensuring compliance with safety standards.

4. Component Replacement Plan

(1) Develop a reasonable component replacement plan based on equipment usage and component service life. For example, seals for feed and discharge valves may need replacement periodically (e.g., every six months or annually). If the fluidization plate of the fluidization device shows severe wear or damage, replace it promptly.

(2) Regularly inspect the wear of vulnerable parts by measuring dimensions and observing their condition. Prepare replacement parts in advance to ensure timely restoration of equipment operation.

III. Annual Maintenance and Overhaul

1. Comprehensive Inspection and Calibration

(1) Conduct a comprehensive annual inspection of the pump, including measuring the wall thickness of the pump body for corrosion or excessive wear. Calibrate all instruments to ensure measurement accuracy meets requirements.

(2) Inspect the coordination between the entire pneumatic conveying system and the pump, such as the tightness of pipeline connections and whether system pressure loss is within the normal range.

2. Component Upgrades and Optimization

(1) Based on technological advancements and actual equipment performance, consider upgrading certain components of the pump. For example, replace with more efficient fluidization devices, more precise instruments, or more durable valves to enhance pump performance and reliability.

(2) Optimize the equipment’s control system, such as updating control programs to enable smarter operation and monitoring, improving automation levels.

3. Recording and Archiving

(1) During each maintenance process, meticulously record details such as maintenance content, time, and replaced components. These records help track equipment performance, predict potential issues, and serve as important references for maintenance history.

(2) Properly archive maintenance records so that, in case of equipment failure, maintenance personnel can quickly understand the maintenance status, accurately diagnose the cause, and take effective measures.
