[Jada Industry and Trade to recommend star product - Seal] 2, replace the seal or shaft and refueling point (1) regulations required check carefully before installing the seal appearance. Seal lip edge and clean the outer surface shall be painted in oil, and hold special tools for press-fit, to ensure that the plane perpendicular to the tool body bore the force evenly and orderly manner to press-fit the oil seal bore, avoid loading crooked or overexert damage seals. (2) measuring the diameter of seal edge, removed from time to spring seal carefully hand finishing flat as possible so that the inner valve seal manufacturers, it may measure several locations averaged. Tianjin valve seal force should be properly measured, can not make deformation measurements. (3) and seal with a journal or bore chamfer should be no burrs, sharp edges, etc., if to be trimmed. (4) When the inspection body must be newly installed shaft, seals should be noted that the spring is good. Shaft oiled, preferably while rotating installation, to prevent seal damaged. (5) For the overhaul of the engine, the seal on the body should in principle replace all seals aging is difficult to distinguish with the naked eye, when all the oil seal replacement engine overhaul is a wise move. (6) of the seal lip, oil leakage at the outer circle, it is sometimes difficult to judge. If this happens you can turn off the engine, until completely cooled dipped in gasoline leakage around the seal and wash doubts Department, and other volatile gasoline finished evenly sprayed with chalk leaks, restart the engine carefully observed, it will be evident with the journal of the seal lip, or seal and seat hole leaks. [Jada Industry and Trade to recommend star product - Seal] (2) preventive measures to ensure the processing quality ① sealing surface. Reduce the roundness and runout tolerances for minimum interference ring impact valve seal, with the gap to meet the requirements, reduce fatigue cracks. ② quality should meet the requirements. The minimum amount of interference is measured based on the quality of seal, therefore, the rubber spring and the tightening of its material properties determine the scope of the use of pressure and temperature affect their life, so that when a user purchases attention. Another valve seal price, when storage is a rubber ring, should prevent heat or sun, in particular, to prevent and paint, gasoline, etc. (can be volatile harmful gases envoy rubber hardening) together, in order to avoid their deterioration. ③ installed to meet the requirements. First oil seal contact surface, water, rust and other contaminants removed. Lips should be no damage during assembly and lubricant coated on the surface of the lip and shaft seals; assembly should be directed to the working pressure of the media pressed on the shaft lip seals may not hold against. Seals should be firmly secured within the housing, without axial movement or rotation of the phenomenon. O-ring assembly, without distortion, and the correct choice of preload. ④ security work requires lubrication system. Ensure lubrication system clean to prevent moisture or other contaminants on the sealing surface caused by corrosion or scratches. Meanwhile, the oil regularly tests its physical and chemical indicators (especially acid number, water and mechanical impurities) does not meet the requirements of the tank should be cleaned, oil change. When repairing or removing piping inside the machine, take the necessary "package", "block", "cover" measures to prevent the oil because the oil is too small or poor exacerbate pressure pulsation, rubber seals to avoid fatigue cracks.
