What is the relationship between the lifespan of a belt conveyor?

Whether the operation of the belt conveyor is stable or not, its service life is closely related to the motor. The problem with such a long motor is ignition, what's going on?

During the entire process of long-term application of belt conveyors, a lot of heat is released inside the machine equipment. If not handled properly, the electric motor will burn out, thereby endangering the service life of the machinery and equipment. There are also many other reasons for electrical damage.

When the transportation friction resistance of the belt conveyor increases, the friction resistance is immediately transmitted to the motor according to the reducer, and there is no indirect buffering protection device. Especially when electrical equipment is restarted due to power outage, the motor starts with load and the frequency of power outage starts increases. The electric motor burned out.

2. There is a gap of 10 to 14mm between the spiral screw blades and the casing of the belt conveyor. Due to the presence of particulate matter in the crushed raw materials, some particles may enter the gap between the spiral auger blades and the casing during transportation. In an instant, a large sliding friction force is generated, which increases its transmission friction resistance, increases the load of the motor during operation, and causes electrical equipment protection devices to trip.

Electric motors are the "heart" of belt conveyors. Once ignited, it will cause the machine equipment to terminate operation and cause some damage. Therefore, temperature rise should be prevented throughout the application process to reduce frictional resistance and friction between the machine and equipment, in order to avoid burning out of the transmission system motor.

Therefore, the output power of the belt conveyor needs to be selected when configuring the motor. It cannot be too big or too small. There are also branded electric motors from large factories, which ensure better quality.

Reasons and cleaning methods for common faults of belt conveyor drum

1. Outer drum of belt conveyor

In areas that are resistant to corrosive chemicals such as corrosion, the surface of the outer cylinder is more severely corroded. Surface erosion will accelerate the damage of the conveyor belt.

2. Sealed transport rollers

The drive shaft generally operates under dusty standards, and sometimes operates in thick water. Due to the hazards of precipitation, both sides of the belt groove drive shaft of outdoor belt conveyors will also penetrate along the gap of the bearing end cover, resulting in the sealing cover and maintenance of the rolling bearing. The architecture is corroded and the lubricating grease is moldy. Reasonable measures to improve the sealing structure and enhance the service life of the roller.

3. Vegetable oil for belt conveyor hand rollers.

Roller bearings should use lubricating grease with high drop points, which is not easy to lose vegetable oil, mold and clump, which will increase the service life of roller bearings and reduce friction.

4. Rolling bearings for belt conveyors

The common faults of rolling bearings are mainly caused by the invasion of moisture, dust or dirt in the body, which leads to corrosion of rolling bearings and mold growth of lubricating grease. The application of one side open polyester ball bearings to increase the diameter of steel balls and the use of rolling bearings to drive shafts have higher radial clearance, which can reasonably avoid the rolling bearings from getting stuck. Its service life is more than five times that of general rolling bearings, and functional wear can be reduced by about 18%.
