What is fluid deposit?
The fluid bearing is a type of bearing that has no parts that actually come into contact with each other. Instead, a thin film of liquid, sometimes under pressure, serves to carry the entire load placed on the bearing. The fluid bearing can use a number of different fluids, the most common oil is the most common, although water and even air are used in some types of fluids. Naturally, the inner deposit has a lot of advantages over the standard spherical bearing, which relies on a series of round steel balls or cylinders to support the load on the bearing.
Most of the bearings of all types are designed to allow one part to move inside the closing part, usually by turning or sliding in some way, as the spindle rotating inside the collar in a high -speed lathe. The mechanical bearings, the most common of which are the ball, rely on the actual moving parts to make this movement easier. However, the fluid has no moving parts,which form the bearing itself, so that the tube is supported by a thin layer of liquid. The fluid bearing may be a closed system or may require a pump to maintain the liquid pressure in the bearing itself.
Liquid static bearing uses a pump to supply a liquid and the lesion-dynamic fluid uses the movement of the parts themselves to pull the liquid into the bearing. Some fluid dynamic deposits may also use a supplementary pump to supply fluids during operations for starting or shutdown to remove wear. Static fluid bearings are often pressure as a function of the operation of the fluid delivery pump. Some types of fluid bearings can even use air or gas as liquid.
Standard mechanical bearings have many disadvantages and several disadvantages compared to liquid bearings. Liquids are usually much quieter, showing much less wear and mohOU to work for an extremely long time with Little or no maintenance, the provision of the liquid layer is maintained. Standard bearings tend to wear and fail, especially under high -speed conditions. A well -known example is a liquid film bearing a water plant for water in Pennsylvania. The original deposit, weighing two tons itself, supported a total load of almost 200 tons, while since its installation in 1912 with continuous use.
However, fluid bearings often consume more energy due to the need for fluid delivery and do not work well under conditions where shock can be delivered to the bearing. A strong impact on the bearing can lead to the compromising liquid film and surfaces coming into contact, which under extreme conditions can lead to catastrophic failure. The fluid bearing can also be slightly less efficient than a standard deposit under similar operating conditions due to the viscosity of the liquid used.
