According to wear control specialist Filter Focus, the majority of smaller scale electric motors operating locally are never greased or lubricated. "In my experience, most maintenance engineers are not even aware that there are bearings on electric motors. As a result, no lubrication is done, and costly and easily-avoidable failure occurs," they explain.
Filter Focus indicates that an electric motor is typically lubricated once at the manufacturing facility. "Generally it is a medium to low quality lubricant that is applied once only, and this is simply not sufficient for the operational lifespan of the motor.
Due to the fact that these motors are often found in confined and hard-to-reach places that are located at-height or under moving conveyor belts, they are unwittingly neglected by site supervisors too."
Lubrication softens the harsh metal-to-metal contact between gears. During this contact, air bubbles are formed when cheap, low-quality lubricants are applied. Filter Focus highlights the fact that this is one of the countless forms of destructive contamination.
"There is often the belief that using cheaper lubrications will save the operation money, however, the expenses associated with the long-term maintenance and wear problems will prove to be exceptionally costly and disruptive."
Due to the harsh operating conditions in Africa, motors and gearboxes become particularly susceptible to rust, corrosion or deterioration. 'These threats arise from the climate, dirty operational environments, as well as low level artisans and cleaners that spray the equipment with water during cleaning, inadvertently damaging the equipment."
An easy-to-apply and environmentally friendly RustPrufe corrosion protection solution for non-porous surfaces eliminates the need to repair damage to these surfaces. Filter Focus notes that RustPrufe – available locally through Filter Focus - is a painted or sprayed-on acrylic polymer emulsion that dries to form a seamless, skin-tight weather and UV-resistant protective barrier.
"RustPrufe is the most convenient, cost effective and user-friendly option to ensure that these costly components are not damaged. What's more, the components do not have to be sanded down or rust treated."
Unlike traditional tape, wax and oil coatings that must be scraped off and cleaned with solvents, RustPrufe does not leave behind a residue. It is also highly-durable. Enquiry no: 100
