Humphrey Valves: 6 Ways Your Hydraulic Components Wear Out

| written by twg

Diffley-Wright Humphrey Valves

Once Humphrey Valves are installed, it begins to slowly wear out. These parts are used to perform simple tasks powered by liquid fluid. The basic components that create a hydraulic system are reservoir, valves, actuators, and pump. The initial rate is low, but gradually the rate increases. If the start-up is not perfect, it can experience serious damage. As you search through our wide range of product lines of valves, actuators, sensors, switches and other products, find out more about how hydraulic components wear out:

Abrasive wear: There is a reservoir that keeps an adequate amount of fluid and there are times when two lubricated surfaces come mix together because of lack of the lubricating oil film. When the Humphrey Valves wear out is called a two-body abrasion. Adhesive wear ends in a transfer of metal that moves from one surface to the other and is torn from its parent-metal surface.

The Humphrey Valve Terms You Need to Know

Adhesive wear: It is very similar to the two-body abrasion and between two lubricated exteriors, there is an oil film. When it is lost the lubricated exteriors scratch while gradually creating heat. After the two oiled surfaces generate the right amount of heat, it sticks to each other and begins to transfer metal from one surface to another. Consequently, microscopic high points re close and separate from their main metal surface.

Fatigue wear: Fatigue wear occurs when the hydraulic fluid is filled with silt-sized hard particles in the bearings and gears.  Point loading may lead to unnecessary stress in the exterior of the component which gradually leads to fracture and breaks down of the exterior elements.

Erosive wear: Erosive wear happens when contaminated fluid has a high amount of silt-sized hard particles. The fluid moves across lubricated surfaces at high velocities working like a rasping ingredient as it wears away in the exterior.

Cavitation wear: The hydraulic pump conveys mechanical energy into hydraulic energy. Sometimes air foams or bubbles produced from oil vapor cluster in the interior of the pump. A micro jet is formed during the bubble collapses to a metal surface.

Corrosive wear: is when there is a loss of surface material after a chemical reaction. If the hydraulic fluid is contaminated by water or any chemical such as acid or heat, it can cause damage to metals. Yellow metals such as bronze are more prone to chemical damaging, and most importantly, if there is water. This wearing out process is very costly to customers. This can be minimized by maintaining proper steps initially.

About the Humphrey Valves Company Diffley-Wright Corporation

Diffley-Wright Corporation was founded in 1963, by Tom Diffley. When Mr. Diffley moved to Florida, after retiring from a distinguished career in the military with the rank of Lt. Colonel, he wanted to continue his productive and successful career by going into business here in the Sunshine State. Over the years, Diffley-Wright has expanded its list of product lines to meet our customers’ needs, and has gained experience in solving problems in a wide range of industries and applications. Our history makes Diffley-Wright very different from the typical distributor of Humphrey Valves components.
