Technical Information –Chain Selection

For Use in Conditions Exposed to Water or Sea Water Drops
When chains are exposed to rainwater or sea water drops, reducing of strength and brittleness by corrosion, sudden wear, bending failure by rusting and roller rotation failure etc. occur. In such scenarios, based on the problem, stainless steel or large guard chains or chains with stainless steel parts are encouraged. The high guard chains are highly rated by our clients. For using chains beneath water, see the following “For In-water Use”.
For In-water Use
When working with chains in water or sea water, brittle fracture and corrosion has to be taken into consideration along with the adverse conditions stated inside the above section. For this objective, we manufacture Water Remedy Conveyor Chains such as Traveling Water Screen Transfer Chain, Rake Chain, Sewage Treatment method Chain, BT Bushing Chain for Water Remedy Drive Unit. Chains with stainless steel parts, with specially coated plates or stainless steel chains are encouraged. On top of that, as corrosion resistant bearings which can be applied in-water, stainless steel, Diesten and Diemec bearings are available.
For Use in Acidic or Alkali Environments
In acidic or alkali environments, worry corrosion, hydrogen embrittlement, intergranular corrosion, and so forth. are triggered in addition to typical problems encountered in other corrosive environments. Segment “5-4 Corrosion Resistance Against Several Substances” lists the corrosion resistance of chain supplies to several substances.
Notably, parts manufactured from 13Cr stainless steel may rust depending on ailments.
Lubrication
Chain daily life is extended by periodical lubrication. Lubrication also lowers the required power. Even so, note that, underneath some service problems, lubrication may adversely have an impact on the chain, or be regulated by law, and so forth.
?Lubrication intervals
It’s a common rule to lubricate about when per week, but based on the circumstances during operation and also the state of lubricating oil, lubricate as desired.
As lubrication methods, coating or drip lubrication is recommended. As for your areas of lubrication, see the next illustration.
For successful lubrication, clean the chain in advance of lubrication. Select a lubrication process ideal for your certain support situation.
?Automatic lubrication (oiling) gadget
We have now numerous automated lubrication (oiling) gadgets. Consult us should you be applying chains in the setup in which lubrication is difficult or should you strategy to automate lubrication.
When Lubrication Isn’t Doable
Lubrication is completely needed for extending the lifestyle with the chain. On the other hand, under some problems, lubrication may not be useful.
Prevent lubrication in the following instances:
one) The chain is embedded in the loads (granular materials, powder, and so forth.).
2) Granular material and powder deposit over the chain when carried by pan or apron conveyors. Right here, lubrication operates adversely.
three) The chain temperature becomes high.
4） Conditions during which lubrication is prohibited by rules or laws.
Once the chain can’t be lubricated or is getting used to convey food, we advise employing our resin, oilless or stainless steel bearings.
For Use with Food
When making use of chains for driving or conveying inside a foods processing machine, in particular once the foods directly contacts the chain, stainless steel is required by FDA regulations.
Stainless steel chains (S3) made of 18-8 stainless steel are advisable. We also manufacture chains with neat physical appearance that give a clean impression designed specifically for use with foods solutions. Get hold of us for far more information and facts.
