Stainless steel lifting chain is the main accessory of many lifting equipment, which has the bearing function of heavy objects. However, the lifting chain will also have failures in the process of use. What are the most common failures?
Before the operation of stainless steel lifting equipment, the lifting chain shall be carefully inspected to ensure that the chain is not damaged before the operation.
The most common failure of the lifting chain in the use process is the chain block. The chain block occurs in the use process due to chain twisting, knotting and other reasons, affecting the normal operation of the equipment. In addition, long-term overloading and diagonal pulling of stainless steel lifting chain may cause cracks, wear, deformation and other phenomena of the chain. If these conditions occur, stop the operation immediately and replace the chain with a new one to avoid danger.
What areas are stainless steel chains particularly suitable for?
As a common power transmission device, the stainless steel chain can reduce the friction force through the hyperbolic arc “chain” design. It is used in places where the power is relatively large and the running speed is relatively slow. It has obvious advantages over belt transmission, such as tanks, pneumatic compressors, etc., but the transmission speed cannot be too fast, because the flexibility of the chain is not as good as belt transmission.
Stainless steel chain is especially suitable for corrosion resistance, cleaning or some areas with harsh chemical requirements, as well as high and low temperature occasions. Stainless steel chain has a large number of applications in the lifting industry and other fields. Stainless steel chain has a certain corrosion resistance, but the corrosion resistance of stainless steel chain is actually limited. The anti-corrosion principle of stainless steel chain is to prevent corrosion reaction through a layer of oxide film formed on the surface of stainless steel. Analysis of Rust Causes of Stainless Steel Chain
There are many reasons for stainless steel chain rusting due to the destruction of stainless steel chain protective film. Here are some common situations.
1. When the stainless steel chain is in the air with some chemical substances, it will adhere to the chain surface and cause corrosion.
2. The stainless steel chain surface is stained with acid, alkali, salt, etc. due to various conditions, which may cause corrosion.
3. The adhesion of organic substances may lead to corrosion of the stainless steel chain surface if organic acids are generated through chemical changes.
4. If the stainless steel chain encounters attachments containing some metal elements or metal particles, and condensate is formed, it may form a battery like state, and electrochemical corrosion will occur, leading to the destruction of this film.
