Common faults and solutions for screw conveyor operation

Screw conveyors are widely used in industrial production, but some faults are common during operation, such as material blockage, bearing damage and reduced conveying capacity. Understanding the causes of these faults and their solutions is the key to ensuring the stable operation of screw conveyors and reducing maintenance costs. The following will discuss these common faults and their corresponding solutions in detail.

Common fault 1: material blocking

Blockage is usually caused by excessive material viscosity, high material moisture content, or foreign matter encountered during transportation. If not handled in time, blockage will cause the conveyor to fail to operate normally.

Solution:

• Choose suitable materials: When choosing materials, try to choose materials with moderate viscosity to reduce the probability of blockage.
• Regular cleaning: Establish a regular cleaning system to promptly remove residual materials in the conveyor and ensure smooth transportation channels.
• Install a debris removal device: Install a debris removal device at the conveyor feed port to prevent large pieces of foreign matter from entering the conveyor and causing blockage.

Common fault 2: bearing damage

Bearings are one of the key components of screw conveyors, and their damage is often caused by insufficient lubrication, aging equipment, or improper installation. Bearing damage can cause the screw conveyor to run poorly or even shut down.

Solution:

• Regular lubrication: Add lubricating oil regularly according to the use requirements of the bearing to ensure that the bearing is well lubricated.
• Regular maintenance: Establish a regular maintenance system for equipment to promptly detect and replace severely worn bearings.
• Correct installation: Make sure the bearing is installed in place to prevent bearing damage caused by improper installation.

Common fault three: decreased delivery volume

A drop in throughput is usually related to worn spiral blades or internal wear in the conveyor. This drop in throughput can affect production efficiency and even cause a production line shutdown.

Solution:

• Check the blades regularly: Check the wear of the spiral blades regularly and replace the severely worn blades in time to ensure stable conveying capacity.
• Maintenance: Perform regular maintenance on the inside of the conveyor to prevent the wear of the internal components of the conveyor from seriously affecting the conveying capacity.

Summarize

Screw conveyors often experience blockage, bearing damage, and reduced conveying capacity during operation. These problems can be effectively solved by selecting appropriate materials, regular cleaning, installing impurity removal devices, regular lubrication and maintenance, correct installation, and regular inspection of blades and maintenance, ensuring the normal operation of the equipment and improving production efficiency.
