How to deal with the failure of the conveying rotary valve during operation
1. Fault diagnosis
Observe the fault phenomenon: Carefully observe the operation of the conveying rotary valve to determine the specific manifestation of the fault, such as abnormal noise, excessive vibration, material blockage, leakage, etc.
Check the equipment status: Check the various components of the conveying rotary valve, including the valve body, rotor, drive device, seals, etc., to see if there is any obvious damage, deformation or looseness.
Analyze possible causes: Analyze possible causes of the failure based on the fault phenomenon and equipment status. Possible causes include changes in material properties, equipment wear, improper installation, operating errors, etc.
2. Common faults and solutions
Abnormal noise
Causes: friction between rotor and valve body, bearing damage, poor gear meshing, etc.
Solution: Stop the machine for inspection, adjust the clearance between the rotor and the valve body, replace damaged bearings or gears, and ensure that the gears mesh well.
Excessive vibration
Causes: Unbalanced rotor, loose installation, drive device failure, etc.
Treatment method: Stop the machine for inspection, balance the rotor, strengthen the installation foundation, check the operating status of the drive device, and repair or replace faulty parts.
Material blockage
Causes: high material humidity, strong viscosity, too fast feed speed, too small gap between rotor and valve body, etc.
Treatment method: Stop the machine to clean the blocked material, adjust the humidity and viscosity of the material, control the feed speed, and appropriately increase the gap between the rotor and the valve body.
leakage
Cause: Damaged seal, improper installation, excessive pressure.
Solution: Stop the machine to replace the damaged seal, reinstall the seal correctly, check the system pressure, and adjust it to the appropriate range.
3. Preventive measures
Regular maintenance: In accordance with the requirements of the equipment maintenance manual, regularly inspect, clean, lubricate and tighten the conveying rotary valve to detect and deal with potential problems in a timely manner.
Correct operation: Strictly follow the operating procedures to start, operate and shut down the equipment to avoid malfunctions due to operating errors.
Monitor material properties: Pay close attention to changes in the properties of the conveyed materials, such as humidity, viscosity, particle size, etc., and adjust equipment parameters in time to adapt to material changes.
Operator training: Train operators to improve their knowledge of equipment and operating skills, and enhance their troubleshooting capabilities.
When a conveying rotary valve fails, it is necessary to promptly diagnose and handle the fault and take preventive measures to ensure the normal operation of the equipment and smooth production.
