How to distinguish the usefulness of the chain

Chain types are complex, widely used, mechanical force to ensure that the user is more convenient to use, for the user to make up for the point of chain knowledge.

The chain is a multi-purpose mechanical base part of a plastic chain with flexible system composed of rigid members. According to the different uses and function areas of the eight-figure chain, the chain can be divided into four kinds: lifting chain, mining chain, high-strength chain and anchor chain. The chain is the primary mechanical base product, because it has the characteristics of both gear drive and belt drive eight-figure chain, and has been widely used in agricultural machinery, automobiles, motorcycles, petrochemical industry, metallurgy and mining braided chain mountain and textile and papermaking. Below, I will introduce to you the characteristics and functions of these useful chains.

1, lifting chain

Lifting chain definition: lifting chain can adjust the length of the chain according to the lifting height of the heavy plastic chain is not the same as that of the crane, and the primary fetching equipment plays a primary role in improving the working power of the crane and expanding the working scope of the crane.

2, mining chain

The mining chain is mainly used for mining, the request contrast is high, and the hard braided chain coefficient is large. At present, the domestic mining chain is divided into B grade, C grade and D grade according to the strength grade, and the raw materials are 25MnV and 23MnCrNIMo54 raw materials. It is divided into flat chain, reinforced chain and anti-corrosion chain: round chain reinforced mine ring chain series, casting vertical ring and special heat treatment, with high tensile strength domestic chain long fatigue life and high tolerance, the best hardness of each ring to reduce the wear between the chain rings, significantly improve the service life; It is known that circular anti-corrosion mining ring chain and compact chain, for corrosive conditions, developed a special raw material for anti-corrosion chain, when the coal mine ground water is particularly corrosive, usually the general chain will attack corrosion pits and fatigue cracks, the circular anti-corrosion mining chain is simply not affected by corrosion, in many international coal mine scraper conveyor has been verified.

3, high strength chain

High-strength chain is one of the chains with very high hardness, mainly used in mining, construction and so on.

4. Anchor chain

Anchor chain refers to the special lock chain that connects the anchor to the ship. It may be said that it is a heavy lock chain that is specially used as a mooring line.

Classification of anchor chain: according to the use of anchor chain is divided into Marine anchor chain and Marine mooring chain; According to the function of the anchor chain can be divided into a stop chain and no stop chain, and the use of Marine anchor chain is widely compared.

Attachment of anchor chain

Accessories of anchor chain: Kent shackle, connecting shackle, Type A swivel shackle, type B swivel shackle, end shackle, swivel.
