What Are the Uses of a Grease Gun?

A grease gun is an everyday tool used for cleaning, lubricating and smoothening grease applied to equipment. A grease gun can be used in a number of different ways depending on the application. A common grease gun is the oil bottle shaped tool, sometimes referred to as a ‘sink gun’ which is often seen in garages and workshops. The basic function of this grease gun is to quickly apply grease through an open aperture to a specified location, usually in a grease container or grease fitting.

The main channels in a grease gun result in a series of holes which lead to the fittings. The channel is generally made with small rubber or plastic grips that have small pump action as the action of the pump pumps air through the small holes. As the air is pumped into the channel, a vacuum occurs and the air pushes the lubricant into the fittings, the grease coming through the small holes.

A standard model of a grease gun consists of a long handle, a round body and a long narrow tube with a single large hole at its end. The tube is constructed so that when it is pushed back, the plunger pushes the air through the aperture. A trigger is fitted to the top of the tube, and it reacts to pressure created by the pumping action of the pump moving air through the tube. The trigger is usually a spring based one which can be activated by the weight of the gun.

Grease Per Stroke Makers: A lever grease gun consists of two parallel cylinders with a single large hole in the middle. One of these cylinders is fitted with a plunger and the other with a trigger. When the lever is squeezed, the plunger expands, forcing air into the other cylinder through a small gap. The air is then pumped into the fittings and the grease fills up the large slot in the bottom of the cylinder.

A lever gun can be either air operated or pneumatic. Air operated grease guns usually have a handle and a pumping action similar to the pump. The air is blown through a tube on top of a piston and then into the fittings below. A spring recharges the gun to give a continuous pumping action. This type of trigger is suitable for use in grease guns that are used to clean large areas and can reach very high pressures.

Pneumatic Grease Pump: A hand-powered grease gun uses an electric motor to generate a squeezing motion. The compressed air is passed through a hand-powered aperture and a trigger mechanism is fitted on top of the mechanism. When the trigger is squeezed, the motor pushes the air through the aperture and creates a suction. As the pressure rises, the air expands and the compressed air fill the entire barrel of the gun. This type of trigger mechanism can reach very high pressures and can be used to pump cement and other heavy materials without too much difficulty.

In addition to the above mentioned trigger mechanisms, there are also Manual Grease Gun primers. They use a tiny priming pin to force a single globular plug into primer slot. It is designed for use in lubricating metal parts. Grease primers for a hand-powered device have to be very precise or they will not work properly. Grease primers for a ten,000 per plunger must also be precise. It is advisable to use a manual grease gun for smaller jobs and a ten,000 per plunger for larger jobs.

Grease guns can also be used to lubricate other equipment such as, pumps, drills, rollers, and saws. Lubrication of these machines is important for ensuring that they continue to run smoothly. Some of these devices come with oil ports that can be used to lubricate screw drives and sockets. Oil can also be used on bolts and nuts to prevent corrosion. A grease gun can be used to lubricate almost any type of gear, motor, or device.
