12 Maintenance Checklist Do the chains shown unusual wear patterns ? Is the chain surface still OK ?Is he elongation still acceptable ?Do the chains run smoothly?Is the adjustments of transfer and dead plates OK ?Are the sprockets still in proper condition ?
13 Maintenance Checklist Does the area around the sprockets collect a lot of dirt ?Are the sprockets fixed properly ?Are the wear strips still in proper conditions ?Does the lubrication system work properly ?Are the corner tracks still in good condition ?Do the chains shown any sign of chemical damage ?Is the catenary sag not to big ?
15 Cleaning Improper cleaning will result in: Damage and dirt to products conveyedIncreased chain load and motor loadIncrease of sprocket wearIncreased wear of wear stripsSticking of chains to the sprockets
16 Cleaning Important aspects of cleaning Cleaning away of broken productsUse warm water and soapCleaning agent must be suitable with chain materialsIn lubrication agent, cleaning agent can be included
17 Cleaning Agents Consider the following : pH-value between 4 and 10 for stainless steel chainsNeutral pH value for plastic chains Frequent cleaning only with pH > 7 and <10 (weekly) Rare cleaning with pH >4 and <6 (monthly with very good rinsing)no free chlorineno ammoniumno phosphoric acidno halogenic agents
18 CleaningLubrication should be on top of the chain and underneath the chainAt curves we recommend to lubricate the inside of the cornersIf the conveyor can not be lubricated during normal running, we recommend to lubricate during a stopBy putting mineral oil on side flexing chain, the lifetime can be increased significantlyRoller chains should be additionally lubricated before installation
