[Three rain valve to recommend the star product - Mechanical seal] Description: Note When removing items a, at the time to carefully disassemble the mechanical seal is prohibited to use hand hammer and flat shovel M74N-70 mechanical seal, to avoid damage to the sealing element. Do one pair of wire hook in the right direction of self-financing gap extends into the driving seat at the seals out. If less than the time scale demolition, should be cleaned before the demolition. b, if both ends of the pump mechanical seals, mechanical seal assembly, disassembly process to take care of each other, to prevent a loss. May initially determine whether to select a balanced structure based on the size and extent of the pressure balance. When the medium viscosity, good lubrication properties, pressure ≤0.8MPa; or low viscosity, lubricity poor M74N-65 mechanical seal, pressure ≤0.5MPa M74N-48 mechanical seal, generally used in non-equilibrium structure; the pressure exceeds the above values, the choice balanced structure; pressure> is 15MPa, can be used in series multi-seal. [Three rain valve to recommend the star product - Mechanical seal] Description: crack graphite ring (ring) is due to vibration, stress rubber ring up big and graphite ring itself caused transmission parts, and coke is is caused due to high temperature, which is common in high-temperature hot oil refinery medium. Secondary seal; play a secondary seal, the secondary seal ring divided compensation and non-compensation of ring seals. It can be an O-ring, V-ring, wedge ring, rectangular ring, etc., used to seal the shaft seal and mechanical seal, mechanical seal and housing. Transmission: transmitting torque from the role. Common Transmission has drive units, forks, pins, key or spring and turns.
