• How to Install the Double Mechanical Seal


    The double-end mechanical seal has the characteristics of short seal axial size and compact structure, so it is especially suitable for occasions where the axial size is restricted. Due to the complex structure of the double mechanical seal, high technical requirements, and strict sealing performanc Read More

  • Basic Knowledge of Metal Bellows Mechanical Seal


    The metal bellows mechanical seal is a single-end, balanced, and arbitrary-rotation metal bellows seal. Since the moving ring O-ring and flexible graphite ring can not compensate, there is no resistance to the movement of the bellows, which is suitable for high temperature and high viscosity media. Read More

  • Performance Requirements and Technical Requirements of Mechanical Seals


    This requirement applies to centrifugal pumps and other similar rotary mechanical seals. The working parameters are: working pressure is 0---1.5691MPa (referring to the actual pressure in the sealed cavity); working temperature is -20--80℃ (referring to the actual internal temperature of the sealed Read More

  • What is Double Mechanical Seals


    Compared with the single end face mechanical seal, the double mechanical seal has a better sealing performance. It is suitable for the sealing of strong corrosion, high temperature, suspended particles and fiber media, gas media, flammable, explosive, volatile, and low viscosity media, and high vacu Read More

  • Quality Inspection Process of Mechanical Seal


    The mechanical seal is a sealing device composed of two sealing elements (stationary ring and moving ring) perpendicular to the shaft, smooth and flat surfaces attached to each other, and relative rotation. It relies on the pressure of the sealing medium to generate the appropriate pressing force on Read More

  • Reasons and analysis of mechanical seal failure


    The failure of mechanical seals is generally known to people after abnormal leakage, abnormal wear, abnormal torque and other phenomena appear. The reasons for the failure are rough as follows:Four main reasons1. The sealing surface is openWhen repairing mechanical seals, 85% of seal failures are no Read More

  • Mechanical Seals


    Mechanical seals are one of the basic mechanical components with precision and complex structure. They are the key components of various pumps, reaction synthesis kettles, turbo compressors, submersible motors, and other equipment. Its sealing performance and service life depend on many factors, suc Read More

  • The Double Mechanical Seal Drawing


    The double end face mechanical seal has two end face seals. If the primary seal fails, the secondary seal can still seal to prevent leakage. Compared with single mechanical seal, double acting mechanical seal has better sealing performance. It is suitable for the sealing of strong corrosion, high te Read More

  • How to Choose the Right Mechanical Seal


    In the selection of mechanical seals, working conditions must be considered, including the appropriate form and material of the seal, and the installation structure. The working conditions that need to be considered generally include: temperature, pressure, and medium. It also needs to consider the Read More
