Choosing An Air Oiled Grease Gun

A grease gun is an indispensable tool in any mechanic’s workshop. It is used to apply grease to working parts, including pistons, cylinders, bolts, nuts, and camshafts. These tools come in different sizes and can be used interchangeably for different application. A grease gun can be handheld or mounted on a stand for easy transportation.

A Grease Gun consists of four main components. The first part is the needle valve, which allows a small quantity of grease to be injected into the valve for easy start-up. The second part is the piston valve, which is used to manipulate the amount of pressure applied to the flow meter, as well as to regulate the flow of oil into the inlet valve. The third component is the rotary vane, which is used to set the viscosity of a given oil by varying the pressure in the nozzle and by manipulating the needle valve. The fourth and last component is the control cylinder, which provides electrical signals to the other parts of the Grease Gun.

A hand-operated grease gun consists of a piston that pushes or pulls a plunger, which causes a diaphragm to open and close. When the plunger comes out, the diaphragm has closed, trapping the oil inside. A trigger mechanism activates the diaphragm, sending a small electrical current through the needle valve. This electrical current activates the rotary vane, causing it to rotate and open the piston, allowing more oil to be released. If the piston is closed when the diaphragm is opened, there will be little or no hydraulic oil released, and if the piston is open when the diaphragm is closed, the oil will be expelled and the device will shut off automatically.

Before purchasing a grease gun, you must determine whether you want to use an open-ended tube or a closed-end tube. The closed-end tube allows the user to control the amount of air-filled space inside the tube, which allows for precise timing of when to apply grease. In contrast, the open-ended tube uses a port that will allow air to fill the entire tube, resulting in less precise control.

Grease guns have many different components, such as basic operating controls, piston, rotary vane, and trigger mechanism, and are available with a variety of different grips, including lever grip, drop-in, hammer-forged, and integral trigger. Grease guns can be purchased with a variety of different pumping mechanisms, including direct drive, displacement pump, spiral drive, and pump jack. Lever grip, drop-in, and integral trigger gun mechanisms all utilize the same basic operation, which is to hold a small piece of metal (located in the center of a rotary vane), and “pump” fluid (which is typically a mixture of hydraulic and oil) up into the barrel. Once the fluid is inside the barrel, it causes it to expand outward, causing a “push” or “pull” against the walls of the barrel.

A typical type of grease gun includes a barrel sleeve and a piston. The sleeve surrounds the barrel and is designed to prevent slippage from happening when the lubricant is pumped up into the gun. The piston functions as the main mechanism for pumping the lubricant through the tube. A plastic or rubber Bleeder Valve is located in the top of the cylinder at the time of firing. This valve is designed to release a small amount of gun grease when the trigger is pulled, preventing excessive wear on the valve.

A fixed tube or plunger gun uses a fixed plastic sleeve surrounding a cylindrical piece of metal (the plunger) that expands and contracts according to the fluid’s pressure. This type of grease gun has fewer parts than other types, but they tend to have a shorter barrel life. Fixed tube guns are usually used on heavy duty equipment or machinery. A variation of this type of grease gun is the rotary vane that features a ball or cylinder that contains hydraulic fluid. These products have a piston that is rotates and pushes the fluid through a tube; the type of valve used here is usually a rubber or plastic Bleeder Valve.

Air operated grease gun is one of the most versatile types available and can be used in a variety of different applications. When you buy an air operated unit, be sure to check that there is at least one trigger, if not more, that can be engaged and released manually. In addition to being able to engage and release the trigger manually, the trigger mechanism on these guns should be easy to use. If you don’t find a trigger with ease-of-use that suits your needs, be sure to look for another product. Air guns are highly customizable, and each user is encouraged to add accessories based on their own personal needs and preferences.
