Introduction Of Chemical Mechanical Seal Technology
Jan 06, 2017

For chemical mechanical seals, the leakage can generally be controlled at 0.2 ~ 3mL; use of pump mechanical seal life of up to a year or more. In theory, most chemical mechanical seals, when the wear rate is small and in hydrodynamic lubrication conditions, it means that the seal should be durable, but it is not the case, the reason is usually the seal can not overcome the accidental Operating condition.

No matter what kind of seal, the seals have a common requirement, namely: tight, less leakage; reliable, long life; simple and compact structure; easy maintenance; low cost; For chemical mechanical seals, the leakage can generally be controlled at 0.2 ~ 3mL; life of up to more than a year in general.

Theoretically, most chemical mechanical seals, when the wear rate is small and in the hydrodynamic lubrication kettle mechanical seal conditions of operation, it means that the seal should be durable, but not the case, the reason is usually there is no seal (Mechanical operation error); installation error; flushing system failure; rapid fluctuations in working conditions and so on. (2) the quality of the mechanical seal;
