In the oil, chemical and other industries used in the compressor's mechanical seal is usually faced with high linear velocity, sealing pair of pv value, heat, wear and vibration, ring rotation spring by the impact of centrifugal force, the media by the stirring effect The problem, usually with a static structure, is that the geometry of the rotating part is symmetrical, reducing the width, reducing the frictional heat or using a controlled membrane mechanical seal. Intermediate ring seals (differential ring mechanical seals) can also be used for high speed seals to reduce the seal face velocity (about half).
FCC face to face static double-ended mechanical seal with PTFE sealing surface, condensation-resistant oil, strict control of the rotating ring to maintain the sealing surface of the verticality of the rotating ring will be fixed and fixed with a wedge Ring seal to prevent leakage at the sleeve and to avoid shaking, the use of narrow carbon graphite seal ring, the correct choice of spring stiffness and the number of springs to maintain the follow-up of static ring. The company is located in:
Centrifugal compressors, screw compressors, expanders, steam turbines and high-speed and high-pressure fluid machinery is widely used gas-dynamic non-contact gas end face seal, which is the most widely used part of the spiral groove gas seal, this gas Face seal is the slot technology for the gas medium seal, the friction between the formation of a thin layer of gas film, so that the seal work in non-contact state. This structure is simple, no wear and tear, long life, high reliability, power consumption at the end, no oil seal (save a huge oil seal system), no leakage during parking (no other parking seal), sealing gas oil pollution , Which combined with magnetic bearing technology, can be no oil lubrication, but the need for gas supply system. This structure is low cost installation, system reliability, enabling long-term stable operation.
