About the gear pump mechanical seal requirements

Mechanical seals, also known as face seal (Mechanicalseal), is a dynamic seal rotating shaft mechanical seal performance and reliable amount of leakage, long life, low power consumption. Need frequent maintenance, and can adapt to the production process automation and high temperature, low temperature, pressure, vacuum, high speed, and various corrosive media. medium containing solid particles and other harsh conditions of the hungry sealing requirements. mechanical seal is rely on one or more pairs of lip perpendicular to the axis relative to the end face of the fluid dynamic pressure and the compensation mechanism stretch * (or magnetic) to keep under seal and then combined with the auxiliary shaft seal leakage resistance achieved devices gear pump mechanical seal requirements, mechanical tamper seals and soft packing seal is as follows:
Benefits:
1) reliable sealing, long-term operation in a sealed state is very stable, very small leak, the leak is about 1% of soft packing seal:
2) long life, in oil, water media generally up to 1 to 2 years or longer in the chemical medium generally work more than six months:
3) rub the power consumption, the friction power is only the soft packing seal 10% to 50%
4) essentially no shaft or sleeve wear:
5) maintenance cycle. Face wear can be automatically compensated, under normal circumstances do not require regular maintenance and repair:
6) resistance to shock, vibration of the rotating shaft and the shaft deflection of the sealed chamber insensitive:
7) applies to a wide range of mechanical numbered seals can be used for high temperature, low temperature, high pressure, vacuum, different rotation frequency, and a variety of corrosive media and media containing abrasive seal.
