Abstract

In view of the non-contact mechanical seal’s problems that the seal clearance and fluid film are unstable at low speed state, and the seal clearance cannot initiative adjust, analyze the structures of traditional mechanical seal, use the TRIZ theory, choose the “stability of object's structure”, “adaptability and versatility” as the improve elements, the “difficulty of monitoring and testing”, “component complexity” as the deteriorate elements. Some inventive principles were obtained from the contradiction matrix, select the “feedback principle” and “replacement of mechanical systems principle”, creative design non-contact magnetic mechanical seal, get open and closing forces by electromagnetic force, achieve the mechanical seal clearance active control by electronic control system, improving the non-contact mechanical seal working stability and reliability, extending service life.
