[Asia Pump Network News] seal is to solve the hydraulic system leakage problem is the most important and most effective part. Now to count the classification of the pump seal and the main role. Pump seals First, the nature of the classification of water pump seals According to the different materials used, the nature of the resulting different categories, 1. High temperature seals 2. High pressure resistant seals 3. Corrosion resistant seals 4. Abrasion resistant seals Circle II, the role of various types of seals V-ring is an axial elastic rubber seals used as a shaft without pressure seal. Sealing lip has better mobility and adaptability to compensate for the larger tolerances and angular deviation, to prevent leakage of internal grease or oil, but also to prevent outside splash or dust intrusion. O-ring is mainly used for static seal and reciprocating seal. For rotary motion seals, only low-speed rotary seals. V-type seals are generally installed on the outer circle or inner circle of rectangular cross-section of the groove from the sealing effect. Y-ring is widely used in reciprocating seals. In addition, there are spring tension (spring storage) ring, PTFE seal material is added in a spring, O-type spring, V-type spring, U-type spring.
