1. Improvement of the transition points between the head and tail of mechanical equipment and the intermediate transfer

The transition length and transition method of the head, tail and intermediate transfer points of mechanical equipment have a great impact on the service life of the equipment. Reasonable transition design must minimize the wear of equipment components, ensure that there is no folding or bulging of equipment components, and no material spillage at the drop point. This will effectively extend the service life of the equipment.

2. Improvement of the belt pressure roller at the concave transition

Practice has proved that the lateral strength of some equipment is insufficient. When starting, the belt-pressing wheel causes excessive force on the equipment, resulting in the tearing of parts. Replacing all the belt-pressing wheels with belt-pressing rollers can perfectly solve this problem, thereby extending the service life of the mechanical equipment.

3. Counterweight and load reduction strategy for boom conveyor belt

In the use of the arm conveyor belt of the stockpile stacker in the coal mine system, the overweight design leads to excessive tension of the equipment, premature cracking and aging. On the basis of meeting the tension of the conveyor belt to carry materials, the service life of the equipment is greatly extended after reducing the counterweight. For example, by reducing the counterweight by 6 tons, the operating volume of a domestic ordinary steel belt has been extended from less than 3 million tons to more than 8 million tons.

4. Material flow direction adjustment

The direction of material flow has an important influence on the service life of mechanical equipment. Adjusting the direction of material flow to align with the direction of equipment operation can significantly increase the service life of the equipment.

5. Local damage repair technology extends service life

(1) Local hot vulcanization: A vulcanizing machine is required, which is suitable for hot fluidization repair of conveyor belts.

(2) Local cold pouring: Liquid polymer composite repair materials can be used, but they need to be cured at room temperature for about 10 hours.

(3) Local cold bonding: Use special repair strips and cold adhesive. This method has the advantages of less manpower and material investment, good wear resistance and reinforcement performance, but it has high requirements on the environment and cannot restore the original flatness of the equipment surface.

(4) Spray repair technology: Several liquid materials are mixed by equipment and sprayed onto the worn surface at high pressure. The curing time is short and it is suitable for local wear over a large area.

6. Reasonable selection of equipment type and maintenance

Reasonable selection of equipment types, timely adjustment of routes along the route according to seasonal changes, and measures such as adding sunshades and winter maintenance will also extend the service life of the equipment.

Through the above strategies, the service life of mechanical equipment can be effectively extended, work efficiency can be improved, maintenance costs can be reduced, and higher economic benefits can be achieved. Companies need to make corresponding adjustments and improvements according to their specific circumstances to ensure the best performance of mechanical equipment.
