Pipe chain conveyor is a widely used equipment for conveying powdery, granular, and small block materials, characterized by compact structure, long conveying distance, and good sealing. Due to its complex operating environment, daily inspections are an important part of ensuring the normal operation of equipment and extending its service life. Especially at the bends of the pipe chain conveyor, due to its special structure and complex stress, it is prone to problems such as wear, chain jamming, and deviation, so it needs to be inspected carefully. The following is a detailed introduction to the daily inspection content at the bend of the pipe chain conveyor:

1. Wear and tear of the chain

The chain is the core component of the pipe chain conveyor, and at bends, due to the rotation of the chain, it is subjected to significant force and is prone to wear and tear. During the inspection, it is necessary to focus on checking the degree of wear of the chain, especially the wear of the chain links and pin shafts. If severe chain wear is found, such as chain link deformation, loose or broken pin shafts, it should be replaced in a timely manner to avoid affecting conveying efficiency or causing equipment failure.

2. Chain wheel wear and alignment

The sprocket at the bend is a key component that drives the chain to turn, and its wear directly affects the stability of the chain's operation. During inspection, it is necessary to check the wear of the sprocket teeth to ensure that the teeth are smooth and free from severe wear. At the same time, check the alignment of the sprocket to ensure good meshing between the sprocket and the chain. If severe wear or poor alignment of the sprocket is found, it should be adjusted or replaced in a timely manner.

3. Wear and deformation of curved shell

The curved shell is an important component for protecting chains and sprockets, as well as a passage for materials to pass through. During inspection, it is necessary to check whether the inner wall of the curved shell is worn, deformed, or cracked. If the shell is severely worn, it may cause material leakage or chain jamming; If the shell deforms, it may affect the running trajectory of the chain. If such problems are found, they should be repaired or replaced promptly.

4. The tightness of the chain

The tightness of the chain is an important factor affecting the stability of the operation of the pipe chain conveyor. At the bend, the change in tightness is more pronounced due to the rotation of the chain. During inspection, it is necessary to check the tightness of the chain to ensure that it is neither too tight nor too loose. Tightness can increase the wear of the chain and sprocket, while looseness may cause the chain to deviate or jump. The tension of the chain can be adjusted by adjusting the tensioning device.

5. Lubrication condition at bends

Lubrication is an important means of reducing chain and sprocket wear, and higher lubrication requirements are required at bends due to complex stress. During inspection, it is necessary to check the lubrication condition at the bend to ensure that the lubrication system is working properly and that there is sufficient lubricating oil on the surface of the chain and sprocket. If insufficient lubrication is found, lubricating oil should be replenished in a timely manner, and the lubrication system should be checked for blockages or leaks.

6. The running trajectory of the chain

The running trajectory of the chain at the bend is easily affected by factors such as deformation of the shell and poor alignment of the sprocket, which can cause the chain to deviate or jump. During inspection, it is necessary to observe the running trajectory of the chain at the bend to ensure good meshing between the chain and the sprocket, without any deviation or jumping of the chain. If the chain is found to be off track, adjust the position of the sprocket or repair the deformation of the shell in a timely manner.

7. Sealing at bends

The sealing of the pipe chain conveyor is one of its important characteristics, and the sealing at the bend directly affects the conveying efficiency of materials and environmental pollution problems. During inspection, it is necessary to check whether the sealing components at the bend are intact and whether there is any material leakage. If the seal is found to be aged or damaged, it should be replaced in a timely manner to ensure good sealing at the bend.

8. Vibration and noise at bends

Due to the complex forces acting on bends, vibration and noise issues are prone to occur. During inspection, it is necessary to check whether the operation at the bend is smooth, whether there are any abnormal vibrations or noises. If excessive vibration or noise is found, it may be caused by chain wear, poor sprocket alignment, or deformation of the housing, and further investigation and resolution of the problem are needed.

9. Cleaning condition at bends

Materials may accumulate at bends during transportation, affecting the operation of the chain or causing blockages. During inspection, it is necessary to check whether there is material accumulation at the bend to ensure that the inside of the bend is clean. If material accumulation is found, it should be cleaned up in a timely manner to avoid affecting the normal operation of the equipment.

10. Tightening of bolts at bends

The connecting bolts at the bend are prone to loosening due to vibration during equipment operation. During inspection, it is necessary to check whether the bolts at the bend are tightened to ensure that they are not loose or missing. If loose bolts are found, they should be tightened in a timely manner to avoid equipment failure caused by loose bolts.

11. Protective devices at bends

The protective device at the bend is an important component to ensure the safety of operators. During inspection, it is necessary to check whether the protective device is intact, damaged or missing. If the protective device is found to be damaged, it should be repaired or replaced in a timely manner to ensure the safety of the operator.

12. Electrical connections at bends

If there are electrical equipment (such as sensors or drive devices) at the bend, it is necessary to check whether the electrical connections are normal during inspection to ensure that the electrical equipment is working properly. If loose electrical connections or equipment malfunctions are found, they should be repaired in a timely manner to avoid affecting equipment operation.

summary

The bend of the pipe chain conveyor is a critical part of equipment operation and a key area for daily inspection due to its special structure and complex stress. By regularly inspecting chain wear, sprocket alignment, shell deformation, chain tightness, lubrication, operating trajectory, sealing, vibration noise, cleanliness, bolt tightening, protective devices, and electrical connections, problems can be detected and solved in a timely manner, ensuring stable equipment operation, extending service life, and improving production efficiency. At the same time, inspection personnel should keep records and form a complete inspection report, providing a basis for equipment maintenance and upkeep.
