Description
Technical field
The utility model relates to shaft seal technical field, is specially a kind of mechanical seal structure.
Background technique
Mechanical seal is a kind of gland seal device of rotating machinery.The equipment such as such as centrifugal pump, centrifuge, reactor and compressor.Because transmission shaft is applied in inside and outside equipment, like this, there is a circumferential clearance between axle and equipment, medium in equipment passes through this gap to outward leakage, if equipment internal pressure is lower than barometric pressure, then air is revealed in equipment, and one therefore must be had to stop the gland seal device revealed.The kind of shaft seal is a lot, the advantage such as to grow, so mechanical seal is in the topmost shaft sealing mode of these equipment in the world today because mechanical seal has leakage rate few and life-span.Mechanical seal is named end face seal again, like this definition in relative national standards: " is kept fitting under hydrodynamic pressure and the effect of compensation mechanism elastic force (or magnetic force) and the cooperation of auxiliary seal by least one pair of end face perpendicular to spin axis and relative sliding and the device of anti-fluid leakage that forms, there are some leaks in traditional mechanical sealing element sealing, in the process of mechanical motion, liquid in machinery can along with the rotation of rotatingshaft, seepage is carried out from the spring in mechanical sealing element, reduce the working life of machinery and mechanical sealing element, damage is caused to machinery, for this reason, we propose a kind of mechanical seal structure.
