[Jada Industry and Trade to recommend star product - Seal] oil seal is sealed with mechanical components, also known as rotary shaft lip seals. Due partly mechanical friction oil seals when entering Tianjin Marine mechanical operation, in order to prevent these oil spills from machinery used in the seal gap. With the development of mechanical technology, in addition to water and oil is also necessary to prevent leakage of chemical liquid and dust, the sediment from the outside intrusion, but also the use of the oil seal case. Seal generally has four parts: a lip end portion: a wedge shape, the ends of the pressure shaft surface, act sealing fluid. Second sealing lip: a flexible elastomeric seal lip under the influence of pressure and vibration of the mechanical design of the pair of sealing fluid movements still maintain a stable sealing effect, and serves to maintain stable contact surface of the shaft lip role of the state . In addition to the spring to improve the sealing lip shaft clamping force, clamping force from maintaining this action. 3 dust lips: no dust lip is in contact with the lip from the spring to prevent dust intrusion deputy role. 4 with portions: the engaging portion is fixed to seal the hole in the chamber, while preventing fluid from leaking from between the alien and the outer circumferential surface of the contact surface and the seal surface of the body cavity effect. Also metal frame is fixed when the seal cavity, the protective effect. [Jada Industry and Trade to recommend star product - Seal] 2, or shaft seal replacement parts and refueling points (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 seal force marine models, uniform and orderly manner to press-fit the oil seal bore, avoid mounted crooked or too much force trauma seal. (2) measuring the diameter of seal edge, do not spring removed, carefully sorting by hand so that the inner seal as flat as possible, it may measure several locations averaged. When measuring the force should be appropriate, not to deform affect the measurement. (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 installed to prevent damaged seal. (5) For the overhaul of the engine, should in principle replace all the seals on the marine organism seal manufacturers, seal aging is difficult to distinguish with the naked eye, when the engine overhaul replacing all the oil seal 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 marine seals, 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 apparent that with the journal of the seal lip, or seal and seat hole leaks.
