Main factors causing oil leakage of chemical pump oil seal
When selecting the chemical pump oil seal, the performance and requirements of the materials delivered by the chemical pump must be fully considered to avoid unnecessary leakage and prevent accidents. The main factor causing the oil leakage of the chemical pump oil seal: the tight seal of the oil seal is the main factor causing oil leakage. When the shaft is worn and forms a groove, even if the new oil seal is replaced, the sealing pressure between the oil seal lip and the shaft is reduced, resulting in an excessive amount of interference between the oil seal lip diameter and the shaft diameter after installation. Analyze the possible reasons for its tight seal:
1. Poor quality of oil seal manufacturing
2. Poor shaft or bearing quality
3. Improper use and maintenance
4. Improper installation
5. Improper storage, adversely affected by environmental pollution
Countermeasures for oil leakage of chemical pump oil seals:
(1) Master and recognize the basic knowledge of fake and shoddy products, and purchase high-quality, standard oil seals.
(2) During installation, if the outer surface of the shaft diameter is low in roughness or has defects such as rust, rust, burrs, etc., use a fine emery cloth or whetstone to smooth it; apply clean engine oil or grease to the lip of the oil seal or the shaft diameter .
Apply sealant to the outer ring of the oil seal, wrap the keyway on the shaft with hard paper to avoid scratching the lip of the oil seal, use a special tool to rotate and press the oil seal inward, and don't smash it hard to prevent deformation of the oil seal Or squeeze the spring and fail; if there is lip cuffing, the spring falls off and the oil seal is skewed, it must be removed and reinstalled. It should be noted that when the shaft diameter is not worn and the spring force of the oil seal spring is sufficient, do not tighten the inner spring without authorization.
(3) When the general working conditions of the oil seal applied to the machinery are bad, the environmental temperature difference is large, the dust is much, and the vibration of the machine tool frequently changes the stress condition of the machine parts, it should be checked, maintained and maintained.
(4) If the shaft diameter and bearing wear seriously; the rubber seal oil is aging or the spring fails, etc., it should be repaired and replaced in time.
(5) The abnormally hot components or assemblies should be promptly eliminated; avoid mechanical overspeed and overload operation to prevent the temperature of the oil seal lip from rising, rubber aging, and early wear of the lip.
(6) Always check the oil level of the engine oil. If there are too many impurities in the engine oil, if there are alloy powders and metal iron filings, replace the engine oil completely. The brand and quality of the oil to be replaced must meet the requirements of the season.
It is recommended to add Maitre Super Sealant & Lubricant to the engine oil. It is an excellent gearbox additive. It can form a film of inert material on the components. The service life can also reduce the noise of the gear box. The use of this Maitre Super Sealing Lubricant will not cause pollution or deteriorate the oil.
