Common Causes and Solutions for Conveyor Chain Failure

Common Causes and Solutions for Conveyor Chain Failure


When the conveyor chain fails, it will affect the normal operation status and even make it impossible to use. Let's learn the common causes and solutions of conveyor chain failure.

Common Causes and Solutions for Conveyor Chain Failure
Conveyor chain
Within industrial machinery, conveyor chains are a very popular method of transmitting power from one component to another, for example from an electric motor to a conveyor system, and can also cope with a variety of harsh working environments. When the conveyor chain fails, it is often caused by the following reasons.

1. Improper selection of materials

Like many mechanical and engineering components, incorrect selection of materials may cause long-term problems in the conveyor chain drive, which will eventually lead to premature failure. Therefore, it is crucial to take the time to choose a conveyor chain that suits your requirements and can withstand the challenges brought by the application. important. In the field of chains, price is a good quality indicator.

By purchasing from experienced manufacturers like ZMIE, customers can also obtain unparalleled technical support and expertise. Whether it is guidance at the time of purchase or troubleshooting during the life of the product, we will provide users with effective solutions.
2. Improper installation

Many conveyor chain failures are due to improper operation during installation. Before installation, we must thoroughly inspect and prepare the equipment, including the cleanliness of the sprocket teeth, and measure the specifications correctly. It is strongly recommended to use a spirit level and a micrometer, especially in the alignment of parallel shafts and sprockets.

 Once in place, in order to adapt to any changes in the installation process, the adjustment of the chain should always be tried through a full circle of the largest sprocket. The general recommendation is to always follow the manufacturer's instructions, especially during the initial installation phase. In order to protect the chain from possible contaminants in the environment (such as dust or dirt particles), partitions can be installed.

3. Improper lubrication

Improper lubrication is the single largest risk factor for premature chain failure, accounting for approximately 60% of failures. The choice of lubricant is the basis to ensure that the roller chain is fully lubricated. It can not only ensure its efficient operation but also help prevent it from being affected by contaminants including moisture.

In most cases, high-quality, detergent-free petroleum-based oils are the preferred lubricants for chains, and their viscosity requirements are determined by the ambient temperature. For applications that encounter abnormal temperatures, the manufacturer's recommendations can be adopted. Heavy oil usually cannot reach all working surfaces of the chain, so it is not recommended.

 There are several different methods that are commonly used to apply lubricant to the drive chain. The best lubrication method depends on the chain speed and the amount of power being transmitted. Manual lubrication is probably the most obvious method, and a brush or oil tank should be used to apply oil on a regular basis. The application of this method should focus on keeping the chain moist, and lubrication is required every eight hours.
Drip lubrication is to guide the oil droplets in the lubricating oil from the drip lubricator to between the edges of the chainplates. Bath or disc lubrication can also be used, from the lower chain of the chain through the oil groove in the drive box. During operation, the oil level should cover the lowest point of the chain.

Disc lubrication requires the chain to run above the oil level. The disc uses a deflection plate to pick up the oil and deposit the oil on the chain. We should choose suitable lubricants according to different applications.

4. Improper Maintenance

If you do not pay attention to cleaning and maintenance during the operation of the chain, it will also lead to premature aging and corrosion of the chain.

Effective inspection and maintenance procedures are essential to ensure the efficient operation and extended service life of all mechanical components, and the chain is no exception. Frequent cleaning and maintenance of the conveyor chain are particularly important for prolonging its service life.

If after reading the above, you feel that it is not very effective for you, many troubleshooting guides are available online through the manufacturer ZMIE.
