Mine high strength round link chain Ø 14 x 50-18 x 64 - C, C, ∅ ∅ 22 * 92-86 - C, ∅ 26 C, ∅ 30 x 34 (126-108 - D, ∅ D

According to the working face of coal mine need to choose the appropriate specifications and quality level of chain, and reasonable installation make chain work smoothly; On the chain conveyor tensioning degree right adjustment is very important, if the chain tension is too loose, in high load condition, the chain is easy to discount, cause serious damage and friction and wear with the chute. A tension and can lead to excessive wear and tear, the inside of the link at the top of the arc and may cause and drive Sprocket wheel meshing is bad, significantly reduce the service life of the chain.

Operator or relevant personnel should be checked daily pre tensioning force to create each strand suitable tension values, especially chain newly installed before 14 ~ 21 d special need to pay attention to. Because with chain and transmission slot need coalesced, the operation of the equipment so few weeks is very critical.

The chain size inspection and testing regularly measuring chain size. Chain after entering the running-in wear out a bit, often referred to as "extension", but this is not the chain itself elongation due to plastic deformation. This process is completed, the wear rate of the chain basic consistent. By measuring the length of three or five ring between Scraper, can link of wear is detected. Correctly measure the mime high strength round link chain of long chain required in flabby condition, usually alternative way is to measure the link's foreign minister, to know the actual size of the chain material measurement, including link how many deformation in the process of our manufacturing. In the case of tensioning can use special gauge inspection for the size of more than one ring, in the whole face every check once, and recorded the measurement results. In the absence of gauge can also take the easy way, with a tape measure. When polycyclic measuring length is longer than the new product length out 2% of the time, it has to do with Sprocket wheel cooperation will start to appear problem, lead to failure. If during the working life of the chain, always adhere to the regular monitoring can predict which link need to be replaced.
