10175002 seals Germany araymond model 10175002 price

10175002 seals are sealing devices installed to prevent leakage at the pump shaft and housing. Common shaft seal types include packing seals, mechanical seals, and dynamic seals. The shaft seal of a reciprocating pump is usually a packing seal. When conveying media where leakage is not permitted, a diaphragm reciprocating pump can be used. The shaft seals of rotary pumps (including vane pumps, rotor pumps, etc.) mainly include packing seals, mechanical seals, and dynamic seals.

10175002 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, cutting 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 in the seal housing and on the shaft, the pressure from the oil seal cutting edge and the contraction force of the self-tightening helical spring generate a certain radial tightening force on the shaft. After a period of operation, this pressure will rapidly decrease or even disappear; thus, the spring can compensate for the oil seal's self-tightening force at any time.

10175002 seal usage instructions

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 that are not temporarily used 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 the oil, the displacement method can be used to compensate.

10175002 seal troubleshooting

1) Main factors causing oil seal leakage: Poor sealing of the oil seal is the primary factor causing leakage. When the shaft wears and forms grooves, even replacing it with a new oil seal may not achieve proper sealing. This is due to reduced contact pressure between the oil seal lip and the shaft, 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 roughness of the shaft diameter is low, or if there are 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 ring 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 in, to prevent deformation of the oil seal or breaking of the spring, which would cause failure. If lip flipping, spring detachment, or oil seal skewing occurs, 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 tension is sufficient. Oil seals used in machinery generally operate under harsh conditions, with large environmental temperature differences, abundant dust, and frequent vibration causing constantly changing stress conditions on components. Therefore, frequent inspection, maintenance, and upkeep are required. If the shaft diameter and bearing are severely worn, or if the oil seal rubber is aging or the spring has failed, repair and replace the corresponding parts promptly. Troubleshoot abnormal heating of components or assemblies immediately. Avoid overspeeding and overloading the machinery to prevent increased temperature at the oil seal lip, rubber aging, and premature lip wear. Regularly check the engine oil level. If there are excessive impurities in the engine oil, such as alloy powder or metal iron filings, completely replace it with new engine oil. The brand and quality of the replacement engine oil must meet seasonal requirements. It is recommended to add Metray Super Sealant & Lubricant to the engine oil. It is an excellent gearbox additive that forms an inert material film on components. It can reduce oil seal leakage, extend the service life of oil seal gears, and reduce gearbox noise. The use of this Metray super sealant lubricant will not contaminate the oil or cause deterioration.
