German cl industrietechnik seals, cl industrietechnik models, cl industrietechnik prices

cl industrietechnik seals can be divided into two main categories: static seals and dynamic seals. Static seals mainly include three types: gasket seals, sealant seals, and direct contact seals. According to working pressure, static seals can be further divided into medium-low pressure static seals and high-pressure static seals. Medium-low pressure static seals commonly use gasket seals made of softer materials with wider widths, while high-pressure static seals use metal gaskets made of harder materials with very narrow contact widths. Dynamic seals can be divided into two basic types: rotary seals and reciprocating seals. Based on whether the seal contacts the components moving relative to it, they can be divided into contact seals and non-contact seals; based on the seal and contact position, they can be divided into circumferential seals and face seals, with face seals also known as mechanical seals. Centrifugal seals and spiral seals in dynamic seals achieve sealing by imparting kinetic energy to the medium during machine operation, hence they are sometimes called power seals.

cl industrietechnik seal construction

The skeleton oil seal structure consists of three parts: the seal body, the reinforcing skeleton, and the self-tightening helical spring. The seal body is divided into the bottom, waist, lip edge, and sealing lip according to different parts. Typically, in the free state, the inner diameter of the skeleton oil seal is smaller than the shaft diameter, meaning it has a certain "interference fit." Therefore, after the oil seal is installed into the seal housing and onto the shaft, the pressure from the oil seal lip edge and the contraction force of the self-tightening helical spring exert a certain radial clamping force on the shaft. After a period of operation, this pressure will rapidly decrease or even disappear, so the spring can compensate for the oil seal's self-tightening force at any time.

cl industrietechnik seal usage guide

1) When the gearbox lubricating oil volume is ≤ 7 liters, the additive amount per liter of lubricating oil is 20‐30ml; 2) When 7‐15 liters, the additive amount is 15‐20ml per liter of lubricating oil; 3) When >15 liters, the additive amount is 10ml per liter of lubricating oil; 4) Oil seals not in temporary use should be stored properly to prevent contamination with oil stains, dust, or exposure to sunlight. 5) When the shaft diameter wears into a "V" shaped groove, causing the contact pressure between the new oil seal lip and the shaft to drop so that it cannot seal oil, the displacement method can be used to compensate.

cl industrietechnik seal troubleshooting

1) Main factors causing oil seal leakage: Poor sealing of the oil seal is the main factor causing leakage. When the shaft wears and forms grooves, even replacing with a new oil seal may not achieve sealing because the contact pressure between the oil seal lip and the shaft decreases, resulting in too small an interference fit between the oil seal lip diameter and the shaft diameter after installation. Taking the S195 diesel engine crankshaft oil seal as an example, the main reasons for poor sealing are analyzed as follows: (1) poor manufacturing quality of the oil seal; (2) poor quality of the shaft or bearing; (3) improper use and maintenance; (4) improper installation; (5) improper storage, leading to adverse effects from environmental pollution. 2) Countermeasures for oil seal leakage due to poor sealing: Master and identify basic knowledge of counterfeit and inferior products, and purchase high-quality, standard oil seals. During installation, if the outer surface roughness of the shaft diameter is low or there are defects such as rust spots, corrosion, or burrs, polish them smooth with fine sandpaper or an oil stone; apply clean engine oil or lubricating grease to the oil seal lip or the corresponding position on the shaft diameter. Apply sealant to the outer ring of the oil seal, wrap the keyway area on the shaft with hard paper to avoid scratching the oil seal lip, and use special tools to rotate and press the oil seal inward. Never hammer or force it, to prevent deformation of the oil seal or breaking the spring, which would cause failure; if the lip flips, the spring falls off, or the oil seal tilts, it must be removed and reinstalled. Note: Do not arbitrarily tighten the inner spring when the shaft diameter is not worn and the oil seal spring elasticity is sufficient. Oil seals used in machinery generally operate under harsh conditions, with large environmental temperature differences, much dust, and frequent vibration causing changing stress conditions on components, so frequent inspection, maintenance, and upkeep are required. If the shaft diameter and bearing are severely worn; if the oil seal rubber ages or the spring fails, repair and replace the corresponding parts in time. Troubleshoot abnormal heating of components or assemblies in time; avoid mechanical overspeed and overload operation to prevent increased temperature at the oil seal lip, rubber aging, and premature wear of the lip. Frequently check the engine oil level; if there are too many impurities in the engine oil, such as alloy powder or metal iron filings, completely replace with new engine oil. The brand and quality of the replaced engine oil must meet seasonal requirements. It is recommended to add Metalex Super Sealant & Lubricant to the engine oil; it is an excellent gearbox additive that can form an inert material film on components, which can reduce oil seal leakage, extend the service life of oil seal gears, and reduce gearbox noise. The use of this Metalex super sealant lubricant will not contaminate the oil or cause deterioration.
