Mining and the use of compact chain operation meth

发布时间:2019/12/24 浏览次数:

The compact chain used in mine can replace the ring chain with the same nominal diameter, and it does not need to transform the original scraper conveyor. The products take high-quality and high-strength alloy steel as raw materials, strictly control the quality of raw materials, and closely monitor every stage and every link of the chain production process, strictly control the quality of each link. The products are rich in variety and complete in grade. Green to do one of the world's chains, to be an excellent chain supplier for the purpose, according to customer demand and actual situation, choose the chain suitable for the site operation environment.

2、 Use and operation method:

1. During the use of the compact chain, it is not allowed to exceed its large allowable working load and its safety factor. The large allowable working load, safety factor and the large tension of the scraper chain during the use are as follows:

Large allowable working load = large breaking force of scraper chain ÷ 2

Coefficient = total breaking strength of scraper chain / large tensile force in scraper chain ≥ 2

Drag force of scraper chain = effective driving power (kw) × load rate of hydraulic coupling (2.25) × driving power (0.75) ÷ chain speed (M / s)

Drag force of scraper chain = effective driving power (kw) × motor load rate (3.0) × driving power (0.78) ÷ chain speed (M / s)

2. When the two speed motor is used, the tension in the scraper chain is calculated according to the low-speed start of the conveyor. Start at low speed with no load to avoid excessive tension. The motor shall be equipped with overload protection system.

3. When using the hydraulic chain tensioner, care should be taken to ensure that the drag force on the scraper chain does not exceed half of the small breaking force specified by the new chain, that is, the safety factor is not less than 2:1.

4. Ensure that the liquid capacity in the hydraulic coupling complies with the specification, so as to avoid the change of the rated power of the hydraulic coupling, the effective driving power and the tension in the scraper chain.

5. When using link connection, vertical or flat link must be distinguished and used correctly to avoid permanent damage to chain and sprocket.

6. The chain must have moderate tension, and try to avoid wear of chain and base plate during operation.
