9 Factors in Choosing an Oil Seal

图片
  From  Oil Seal Manufacturers , we know that the primary causes of external lubricant leakage in pumping systems, hydraulic presses, gearboxes and tanks are incorrect selection, improper application, improper installation and improper maintenance of sealing systems. These problems can be overcome by better understanding the types of seal materials available, redefining the selection process, and consistently applying sound replacement and maintenance practices.     There are a number of variables that must be considered when selecting oil seals. When specifying oil seals, designers and maintenance engineers must evaluate nine factors:   Shaft Speed The maximum shaft speed allowed is determined by the shaft finish, runout, concentricity of the housing bore and shaft, the type of fluid being sealed, and the type of oil seal material.   Temperature The temperature range of the mechanism where the oil seal is to be installed must not exceed the temperature range of the oil seal elastomer.

What Materials Are Available for Oil Seals

图片
  An   oil seal   is also known as a rotary shaft seal, shaft seal, lip seal, elastomeric lip seal, or any variation of these. It is a simple device used to remove dust, dirt, water or any other contaminants while retaining the lubricant in a rotary shaft device. Often, it has been developed as a way to protect rotating shaft bearings. The following shows the selection of  oil seal materials ​. 1,  Aflas,  temperature range between -10°C and +205°C, made of special fluoroelastomer (FKM), resistant to steam, petroleum, amine corrosion inhibitors and hydrogen sulfide. 2, Carboxylated Nitrile , temperature range -55°C to +135°C. Carboxylated Nitrile seals are made of a low temperature resistant compound that also has excellent abrasion resistance. Resistant to water and oil, 3,  Viton , temperature range -20°C to +205°C, FKM fluorocarbon seals are highly resistant to solvents and petroleum oils. As a result, they are ideally suited for high temperature installations and have low compressi

  How important is the correct installation of  oil seals ? Even if the oil seal has been correctly selected and the grooves in the seal mounting area have been reasonably sized, but the seal has not been installed scientifically and correctly, there is no guarantee that it will perform 100% of its intended function.  Honglei  takes you through how the oil seal should be installed.   Valve Oil Seal   How should the oil seal be installed? 1.When installing the oil seal, the key should be removed first before installing the oil seal.   2.When installing the oil seal, apply oil or lubricant first and round off the shaft end and shoulder of the oil seal.   3.When installing the oil seal, be sure to make the lip end of the oil seal face towards the side of the oil being sealed, and avoid reverse assembly of the oil seal.   4.Assemble the oil seal with professional tools to avoid damage to the oil seal lip when the oil seal lip passes through the thread, keyway, spline, etc.   5.No violent o

How to Quickly Repair a Bad Valve Seal?

图片
  If you suspect that you have a bad  valve seal , there are a few steps you can take to try to repair it:     Clean the valve and surrounding area Use a small brush or toothbrush to clean any dirt or debris from the valve and the area around it.   Apply a penetrating oil Spray or apply a penetrating oil, such as WD-40, to the valve stem and the surrounding area. This can help to loosen any stuck or seized parts and make it easier to remove the valve.   Remove the valve Use a valve removal tool, such as a valve spring compressor, to remove the valve from the engine. Be careful not to damage the valve or the valve seat while removing it.   Inspect the valve seal Once the valve is removed, inspect the seal for any visible damage or wear. If the seal is damaged, it will need to be replaced.   Replace the valve seal Use a seal replacement tool to remove the old seal and install a new one. Make sure the new seal is properly seated and aligned before reassembling the engine.   Reassemble the

What Happens if Valve Stem Seals Are Bad?

图片
  If the  valve stem seals  in an internal combustion engine are bad, it can cause a number of problems. One of the most common symptoms is oil consumption. The engine may burn oil excessively or leak oil into the combustion chamber, which can lead to increased emissions and reduced fuel efficiency.   valve stem seals Other symptoms of bad valve stem seals may include: Decreased power and performance If the seals are not sealing properly, it can allow too much or too little air and fuel to enter the combustion chamber, which can affect the engine's performance.   Rough idle The engine may run poorly or vibrate at idle if the seals are not sealing correctly.   Oil burning smell If the seals are allowing oil to leak into the combustion chamber, it can cause a burning oil smell.   Smoke from the exhaust A faulty valve stem seal can cause oil to be burned in the combustion chamber, which can result in white or blue smoke being emitted from the exhaust.   Oil consumption If the valve st
