Classification and definition of different hydraulic and mechanical seals?
[Labels: keywords]
Between the daily use of hydraulic seals and mechanical seals, it is generally difficult for people to distinguish their differences, which is a hydraulic seal, which is a mechanical seal, often mistaken for the same kind of sealing element. Structural classification and definition of hydraulic seals and mechanical seals. "Mechanical Seals" Mechanical Seals "First of all, we must clearly understand that hydraulic seals are rubber sealing material components with pressure requirements and smoothness (cleanliness) requirements. The mechanical seal is a kind of design, one of the complex mechanical components, such as a variety of pumps, reaction synthesis kettle, turbine compressor, submersible motor and other equipment key components. Its sealing performance and service life depend on many factors, such as selection, accuracy of the machine, correct installation and use.
1. mechanical seal type classification: container seal series, light mechanical seal series, heavy mechanical seal series, etc.
Model classification of 2. hydraulic seals: lip seal ring, V-shaped seal ring, U-shaped seal ring, Y-shaped seal ring, YX-shaped seal ring and hydraulic cylinder commonly used combination seals are mainly bud ring, grid ring and Stel seal.
3. secondly, when the sealing ring is purchased and repaired, the general people will buy according to the size and color of the sample, which will only increase the difficulty of purchasing, and may not be able to select the right product. Therefore, we need to consider selecting appropriate seals to improve the accuracy of purchasing seals in terms of sealing (active point), direction of movement, temperature, sealing ring size, groove size, and pressure.
