Any industrial facility that does regular business will use lip seals. However, if you're noticing repeated leaks and other failures of these seals, you may assume that the seals themselves are the problem. In fact, there are many possible reasons for lip seal failure; any one of these could be the root of your seal problem.
1-They're Too Old
Do you have a record of the last time lip seals were changed? if not, there's a real possibility that the seals are simply worn down from being used for too long. A maintenance schedule doesn't usually include seal replacement, but you should track when new lip seals are installed so you can also track when they need to be switched out.
2-Inappropriate Seal Material
The lip seals you're using are not always the best for certain equipment. You or others may simply be assuming that all lip seals are interchangeable, which is not always the case. Various lip seals are constructed for certain liquids, temperatures and similar factors. if you aren't sure that the lip seal goes where you're putting it, you must find out. To do so, check with equipment manufacturers about the best lip seals for their machines.
Even if you're sure that the seals are appropriate for use, the entire system may be hitting high temperatures that affect your seals. To prolong lip seal life and protect the system, you can take action and decrease overall system heat, if possible. This may include shutting down machines that aren't in use or painting metal parts to cool down the system. Lip seals should then need to be replaced less frequently.
Sometimes lip seal destruction is related to chemicals flowing through the lines. If your facility has switched over to new chemicals or additives, the seals you've grown accustomed to using may need to be re-evaluated.
It's not only your machines that must be considered. Rain, mud, ice and snow can also affect lip seals. Be sure the seals and pipes are cleaned regularly to decrease the chances that these substances will cause seal degradation.
System filters that themselves need changing can mean trouble for lip seals. Any debris that bypasses torn or compromised filters could become implanted in the seals and tear or damage them. Ensure filter changes happen often.
Protecting lip seals is possible. Speak to managers and staff about these suggestions and treat these seals,as you do all the rest of your equipment, with care and attention.
