German FILTON seals FILTON models FILTON prices

FILTON seals refer to devices that prevent fluid leakage, formed by at least one pair of end faces perpendicular to the axis of rotation. These faces remain in contact and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, along with the assistance of auxiliary seals. When the auxiliary seal of the compensation ring is a metal bellows, it is called a bellows mechanical seal. There are mainly the following four types of components: a. Primary sealing elements: rotating ring and stationary ring. b. Auxiliary sealing elements: O-rings. c. Clamping elements: springs, thrust rings. d. Drive elements: spring seats and keys or fixing screws.

Advantages of FILTON seals

1) Oil seals have a simple structure and are easy to manufacture. Simple oil seals can be molded in a single step; even for the most complex oil seals, the manufacturing process is not complicated. Metal-cased oil seals only require processes such as stamping, bonding, inlaying, and molding to combine metal and rubber into the required oil seal. 2) Oil seals are lightweight and consume little material. Each oil seal is a combination of thin-walled metal and rubber parts, resulting in minimal material consumption and very light weight for each seal. 3) Oil seals require small installation space and have small axial dimensions, making them easy to machine and allowing for compact machine design. 4) Oil seals offer good sealing performance and long service life. They have certain adaptability to machine vibration and spindle eccentricity. 5) Oil seals are easy to disassemble and convenient to inspect. 6) Oil seals are inexpensive.

Precautions for FILTON seals

1) Preparation and precautions before startup: a, comprehensively check whether the mechanical seal, as well as auxiliary devices and pipeline installations, are complete and comply with technical requirements. b, perform a static pressure test on the mechanical seal before startup to check for leakage. If there is significant leakage, identify the cause and eliminate it. If this is ineffective, disassemble, inspect, and reinstall. The static test pressure is generally 2~3 kg/cm². c, rotate the pump according to its direction of rotation to check if it moves lightly and evenly. If rotation is difficult or stuck, check whether assembly dimensions are incorrect or installation is improper. 2) Installation and shutdown: a, keep the seal chamber filled with liquid before startup. For media that solidify, use steam to heat the seal chamber to melt the medium. Manual rotation must be performed before startup to prevent sudden startup from causing the soft ring to shatter. b, for mechanical seals using an external seal oil system, start the seal oil system first. Stop the seal oil system last after shutdown. c, do not immediately stop the cooling water for the seal oil chamber and face seal after stopping a hot oil pump. Wait until the oil temperature at the face seal drops below 80 degrees before stopping the cooling water to avoid damaging seal parts. 3) Operation: a, if slight leakage occurs after pump startup, observe for a period. If the leakage does not decrease after continuous operation for 4 hours, stop the pump for inspection. b, the pump operating pressure should be stable, with pressure fluctuations not exceeding 1 kg/cm². c, avoid cavitation during pump operation to prevent dry friction on the sealing surfaces and seal damage. d, frequently check the sealing condition. During operation, if leakage exceeds the standard (no more than 5 drops/min for heavy oil, no more than 10/min for light oil), and there is no improvement within 2-3 days, stop the pump to inspect the sealing device.

FILTON 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, replacing with a new oil seal may still fail to seal because the contact pressure between the oil seal lip and the shaft decreases, resulting in insufficient interference fit between the oil seal lip diameter and the shaft diameter after installation. Taking the S195 type 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 contamination. 2) Countermeasures for leakage due to poor oil seal sealing: Acquire basic knowledge to identify counterfeit and inferior products, and purchase high-quality, standard-compliant oil seals. During installation, if the outer surface of the shaft has low roughness or defects such as rust spots, corrosion, or burrs, polish it 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 circle of the oil seal. Wrap the keyway area on the shaft with hard paper to avoid scratching the oil seal lip. 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 of 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 has sufficient elasticity. 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; therefore, frequent inspection, maintenance, and care are required. If the shaft diameter and bearing are severely worn, or 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 promptly; avoid overspeeding and overloading the machinery to prevent increased temperature at the oil seal lip, rubber aging, and premature lip wear. Frequently check the engine oil level. If there are excessive 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 replacement engine oil should meet seasonal requirements. It is recommended to add Met-Rx Super Sealant & Lubricant to the engine oil. It is an excellent gearbox additive that forms 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 Met-Rx super sealant lubricant will not contaminate the oil or cause deterioration.
