A water softener works through a process called ion exchange, where hard minerals are exchanged for sodium ions. This process not only softens the water but also helps to extend the lifespan of your plumbing and appliances. Softened water leads to cleaner dishes, brighter laundry, and a smoother feel on your skin and hair.

In the UK, customers have a range of options for purchasing oil seals. There are several reputable UK gasket manufacturers that offer a wide selection of oil seals to meet various industrial needs.

6. Proper installation is key to effective oil seal performance.
- Unlike gasoline engines, diesel engines rely on compression ignition to ignite the fuel-air mixture. This means that diesel engines do not require a spark to ignite the fuel. However, diesel engines still require spark plugs to facilitate the combustion process. Diesel spark plugs are designed to withstand the high temperatures and pressures found inside a diesel engine's combustion chamber.

3. TEMPERATURE: Similar to the pressure level, you need to know what temperature your machinery can operate at. You need to choose a seal that can withstand the heat or cold. PTFE have the widest rang of temperature, making them a safe option when you are uncertain of the range.
The group of oil seals used in dynamic applications include radial shaft seals that seal a rotating shaft around its circumference. They are also known as lip seals, but in this blog we will use the term oil seals.
(the volume of oil, etc., pushed back at the lip contact area per unit of time)
Under the action of the skeleton oil seal, the rigidity of the oil film just makes the oil film and the air contact end form a crescent surface, which prevents the leakage of the working medium and realizes the sealing of the rotating shaft. The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak; if the thickness is too small, dry friction may occur, causing the oil seal and shaft to wear; if there is no oil film between the sealing lip and the shaft, it is easy to cause heat and wear. . Therefore, when installing, it is necessary to apply some oil on the sealing ring, and at the same time ensure that the skeleton oil seal is perpendicular to the axis line. If it is not perpendicular, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also lead to excessive sealing of the lip. wear. During operation, the lubricant in the casing seeps out a little, so that it is ideal to form an oil film on the sealing surface.

The perfect solution to this is to always use an oil seal that fits properly; the right size of the seal should be used. And in other cases, backup devices should be used to avoid the buildup of clearance gaps within the mating edges.

PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.
