A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually from a grease cartridge to a grease fitting or 'nipple'.
The channels behind the grease nipple lead to where the lubrication is needed. The aperture may be of a type that fits closely with a receiving aperture on any number of mechanical devices. The close fitting of the apertures ensures that lubricant is applied only where needed, making it an efficient lubrication equipment for maintaining high quality grease gun performance.
Preparation
Cleaning the auto grease gun: Make sure the automotive grease gun is clean inside and out.
Selecting lubricants: Choose the right lubricant based on the equipment requirements.
Inspecting the equipment: Make sure the equipment parts that need lubrication are clean and free of impurities.
Correct operation
Aiming the nozzle: Aim the nozzle of the hose grease gun at the part that needs lubrication.
Slowly pressing: Slowly press the trigger on the grease gun hand to control the flow of lubricant.
Evenly applying: Make sure the lubricant is evenly covered on the equipment surface.
Subsequent maintenance
Cleaning heavy duty grease guns: Clean the lubrication gun immediately after use to prevent lubricant residue, no matter what types of grease guns you purchase.
Inspecting the equipment: Check the lubrication of the equipment regularly to ensure its normal operation.
Storing grease gun: Store the pump grease gun in a dry, clean place to prevent contamination.
High Grease Gun Pressure
A high-pressure manual grease gun such as air operated high pressure grease gun is designed to deliver from 2,000 to 15,000 psi. Overpressure the pneumatic high pressure grease gun will damage the bearing seals, which rarely handle more than 500 psi. Symptoms of overpressuring air operated grease gun include collapsed bearing shields, damaged bearing seals, grease driven into electric motor windings, and safety and environmental issues.
Regreasing Frequency
Managing regreasing frequencies to optimal conditions is necessary to avoid long-term machine health problems. If the frequency is too long, symptoms may include lubricant starvation, which promotes wear, friction and grease contamination. If the frequency is too short, excessive grease consumption and safety and environmental issues may occur.
Overgreasing and Undergreasing
For achieving better grease gun working result, it is important to know the exact amount of grease necessary for your greasing application to avoid overgreasing or undergreasing. Symptoms of overgreasing include damaged seals and motor windings, environmental issues, and fluid friction, which leads to increased heat generation, higher grease oxidation rates and higher energy consumption. Symptoms of undergreasing include bearing starvation, which results in friction wear and increased contamination.
