A grease gun is an indispensable tool for those who work in industrial workshops and garages. They are used to apply oil or grease to a variety of surfaces, such as pipes, cooling fans, pumps and many more. A grease gun works by introducing oil or grease into a bore or channel through an opening that has a small hole. The gun can be used with standard air compressors or even on non-standard electrical equipment.
The function of the grease gun consists of a long metal tube attached to the end of a handle. The length of the tube determines how much lubricant is added to the bore or channel. The grease gun’s nozzle is selected based on the amount of lubricant to be added. The nozzle can either pull the fluid up into the feeder or push the fluid against the walls of the bore to fill it there.
The standard model of grease gun consists of a large cylindrical housing containing a crank handle and a pair of rotating brushes. To engage the brushes, you simply rotate the handle clockwise, while keeping the cap in place. The tank holds enough lubricant to cover the opening in a given timeframe, depending on the size of the opening. A small tube, generally made out of steel, leads to a chamber that contains a pump. This pump, when turned on, forces a stream of grease upwards through the tube and into the housing.
The main benefit of a grease gun over other mechanisms is that it provides automatic application of lubricant to the appropriate parts without manual interference. Another benefit is that it eliminates the need for a trigger mechanism that opens and shuts the aperture. Grease comes in varying viscosities, with lower levels meaning that they are more viscous and hence more difficult to pump into an aperture. A capillary action is needed to push the grease into the bore, which also results in a faster pumping process and more consistent results. Grease guns can also be adjusted to open and close by adjusting the length of the piston. There is also a mechanical trigger mechanism that can be activated to increase or decrease the aperture in accordance with the level of lubricant.
In order to start the mechanism, simply turn the crank to start the mechanical pump that pumps the grease into the aperture. When it reaches full force, the plunger shoots out a spray of lubricating fluid. The excess is expelled through a tube that leads to the nozzle. As the grease continues to move through the bore, it bumps against the piston which causes it to be propelled outwards into the reciprocating movement of the crank and the rest of the assembly. The excess lubricant is expelled through the tube on top of the crank and then out through the nozzle, leaving the capillary ring empty. This causes the valve to open so that more lubricant can be pumped into the area.
The next step is to pull the trigger, releasing the plunger and spraying the remaining lubricant into the area. Pulling the trigger again will cause the plunger to shoot out the barrel and continue on its path. Once this has been repeated a number of times, the grease gun should become fully functional. At this point it is possible to pull the trigger and shoot a quantity of lubricant into the barrel and extractor, depending on the type of grease gun. This should allow the gun to do its job, and the barrel should return to its original form.
Another method of repairing a grease gun is through the use of a pneumatic grease gun repair kit. These repair kits contain a tank that holds a large quantity of water, a piece of pneumatic equipment such as a pump, a nozzle, and zerk fittings. It is important to ensure that you have enough water in the tank to cover the tank’s entire circumference and make sure that the pieces of equipment are well-lubricated.
Zerk fittings are special holes that allow a fluid to flow through a piece of equipment without any resistance. These fittings are used in order to apply a sufficient amount of lubricant to the working parts of a machine without clogging up the lines or making it difficult for the fluid to move. The advantage to using grease guns in this manner is that they can apply enough lubricant to prevent damage or clogging to the lines. They also allow for a more expedient way of returning a machine to normal operation when it is damaged.
