Grease Gun
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. There are four types of grease gun: #Hand-powered, where the grease is forced from the aperture by back-pressure built up by hand-cranking the trigger mechanism of the gun, which applies pressure to a spring mechanism behind the lubricant, thus forcing grease through the aperture. #Hand-powered, where there is no trigger mechanism, and the grease is forced through the aperture by the back-pressure built up by pushing on the butt of the grease gun, which slides a piston through the b ...

Workshop
Beginning with the Industrial Revolution era, a workshop may be a room, rooms or building which provides both the area and tools (or machinery) that may be required for the manufacture or repair of manufactured goods. Workshops were the only places of production until the advent of industrialization and the development of larger factories. In the 20th and 21st century, many Western homes contained a workshop in either the garage, basement, or an external shed. Home workshops typically contain a workbench, hand tools, power tools, and other hardware. Along with the practical application of repairing goods, workshops are often used to tinker and make prototypes. Some workshops focus exclusively on automotive repair or restoration although there are a variety of workshops in existence today. Woodworking, metalworking, electronics, and other types of electronic prototyping workshops are among the most common. Backshop In some repair industries, such as locomotives and air ...

Automobile Repair Shop
An automobile repair shop (also known regionally as a garage or a workshop) is an establishment where automobiles are repaired by auto mechanics and technicians. Types Automotive garages and repair shops can be divided into following categories: Service Station * First appearing in the early 1900s, many filling stations offered vehicle repair services as part of their full service operation. This once popular trend has declined significantly over the years as many locations found it more profitable to exchange vehicle service bays for grocery isles, which ultimately lead to the emergence of the quick oil change industry. Lubrication/Safety Shop * Commonly referred to as a quick lube or express service shop, this type of facility specializes in preventive maintenance and safety inspections rather than repairs. Product sales are typically limited to automotive fluids, belts and hoses. With a focus on basic procedures, labor is often performed by entry-level technician ...

Tool
A tool is an object that can extend an individual's ability to modify features of the surrounding environment or help them accomplish a particular task. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. Early human tools, made of such materials as stone, bone, and wood, were used for preparation of food, hunting, manufacture of weapons, and working of materials to produce clothing and useful artifacts. The development of metalworking made additional types of tools possible. Harnessing energy sources, such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an inflection point in the use of tools. The introduction of widespread automation in the 19th and 20th centuries allowed tools to operate with minimal human supervision, further increasing the productivity ...

Lubrication
Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology. Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic or hydrostatic pressure, which reduces solid body interactions (and consequently friction and wear). Depending on the degree of surface separation, different lubrication regimes can be distinguished. Adequate lubrication allows smooth, continuous operation of machine elements, reduces the rate of wear, and prevents excessive stresses or seizures at bearings. When lubrication breaks down, components can rub destructively against each other, causing heat, local welding, destructive damage and failure. Lubrication mechanisms Fluid-lubricated systems As the load increases on the contacting surfaces, distinct situations can be observed ...

Grease Fitting
Grease fitting on a bearing A grease fitting, grease nipple, Zerk fitting, grease zerk, or Alemite fitting is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun. Design Grease fittings are permanently installed by either a (taper) thread or straight push-fit ('hammer in') arrangement, leaving a nipple connection that a grease gun attaches to. The pressure supplied by the grease gun forces a small captive bearing ball in the fitting to move back against the force of its retaining spring. The arrangement is thus essentially a valve that opens under pressure to allow lubricant to pass through a channel and be forced into the voids of the bearing. When the pressure ceases, the ball returns to its closed position. The ball excludes dirt and functions as a check valve to prevent grease escaping back out of the fitting. The ball is almost flush with the surface of the fitting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graco (fluid Handling)
Graco is an American industrial company specializing in the development and manufacturing of fluid-handling systems and products. The company is headquartered in Minneapolis, Minnesota and markets its products to customers worldwide. History Russell Gray, a Minneapolis parking lot attendant, founded Gray Company, Inc. in 1926 with his brother Leil Gray to produce and sell Russell's air-powered grease gun, invented in response to cold weather making hand-powered grease guns inoperable. Sales their first year of operation were $35,000. By 1941, annual sales had reached $1 million. They capitalized on opportunities in defense-based lubricating needs during World War II. After World War II, Graco began expanding outside of lubricant handling, developing a paint pump and direct-from- drum industrial fluids pumps. By the mid-1950s they had expanded to $5 million in sales and 400 employees, and were servicing fluid handling needs in a wide variety of industries. Leil Gray died in ...

Grease (lubricant)
Grease is a solid or semisolid lubricant formed as a dispersion of thickening agents in a liquid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil. A common feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease. This change in viscosity is called shear thinning. Grease is sometimes used to describe lubricating materials that are simply soft solids or high viscosity liquids, but these materials do not exhibit the shear-thinning properties characteristic of the classical grease. For example, petroleum jellies such as Vaseline are not generally classified as greases. Greases are applied to mechanisms that can be lubricated only infrequently and where a lubricating oil would not stay in position. They also act as sealants to prevent ingress of water and incompressible mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M3 Submachine Gun
The M3 is an American .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3.Iannamico, Frank, ''The U.S. M3-3A1 Submachine Gun'', Moose Lake Publishing, , (1999), pp. 14, 22–24, 34–39, 44–46, 54–55, 59–63, 67, 73–74 The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun, but was cheaper to mass produce and lighter, although, contrary to popular belief, it was less accurate. The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser," owing to its visual similarity to the mechanic's tool.Ingram, Mike: ''The MP40 Submachine Gun'', p. 85. Zenith Imprint, 2001. The M3 was intended as a replacement for the Thompson, and began to enter frontline service in mid-1944. The M3A1 variant was used in the Korean War and later conflicts. The M14 rifle, adopted in 1959, was intended to replace the M3A1 (as well as the M1 Garand, M1918 Browning Automatic Rifle and th ...

Grease Gun Injury
A high pressure injection injury is an injury caused by high-pressure injection of oil, grease, diesel fuel, gasoline, solvents, water, or even air, into the body. The most common causes are accidents with grease guns, paint sprayers, and pressure washers, but working on diesel and gasoline engine fuel injection systems as well as pinhole leaks in pressurized hydraulic lines can also cause this injury. Additionally, there is at least one known case of deliberate self-injection with a grease gun. Although the initial wound often seems minor, the unseen, internal damage can be severe. With hydraulic fluids, paint, and detergents, these injuries are extremely serious as most hydraulic fluids and organic solvents are highly toxic. Delay in surgical treatment often leads to amputations or death. But even with pure water or air, these injuries cause compartment syndrome Compartment syndrome is a condition in which increased pressure within one of the body's anatomical compartm ...

Drum Pump
Drum pump, barrel pump, and transfer pump refer to pumps that are used to empty barrels, tanks, IBCs and drums. Many liquids used on manufacturing and processing plants are delivered in 100 or 200 litre barrels and are too heavy to tip to empty the liquids inside. Drum pumps range from simple siphon based devices to sophisticated highly-engineered machinery. Considerations * Function - Is the purpose simply to empty the drum completely in one operation, to allow dispense-on-demand operations, or to provide a metered flow to a subsequent operations? Flow rate, pressure, control systems, etc. need to be specified. * Liquid being pumped - Product viscosity determines the type of pump mechanism. Heavy viscous liquids usually require positive displacement pumping head. * Special product characteristics - Acids, corrosives, or reactive liquids need special materials in the drum pumps. Food and pharmaceutical liquids also need special materials as well as a means of regular cleanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
