Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of mechanical seal device, particularly a kind of integrated mechanical sealing device for pump.
Background technique
All the time, people adopt the multiple sealing material of one type of filler, and the outside leakage rate of liquid from the liquid pump housing along main shaft constantly reduced.Although the liquid pump that adopts in the modern crafts flow process is still continued to use the most ancient Seal Design Zhao stuffing box widely,, and be familiar with by the staff of factory again because its starting expense is low.
Yet raising along with environmental protection and human health requirement; Leakage to machine requires also to improve constantly; Adopt the gland sealed method can not be accepted by people gradually, particularly to liquid commonplace, that corrosivity is stronger in the modern crafts flow process.Therefore, in practical application, replace the gland sealed situation more and more with mechanical seal.
Mechanical seal mainly is made up of two seal rings (rotating ring, stationary ring) perpendicular to axle; The ear end face of rotating ring, the front-end face of stationary ring contact; And under the effect of the elastic force of hydrodynamic pressure or compensation mechanism; Form maintenance and fit tightly the also sealing surface of slide relative, and under the cooperation of auxiliary seal, constitute the device that prevents leak of liquid.Face pressure between stationary ring and the rotating ring (the average impacting force on the seal face unit area) directly has influence on sealing effect; Face pressure can not be too big when stationary ring and rotating ring were fitted; Face pressure is crossed conference and is made the end face heating, and wearing and tearing are accelerated, and frictional power loss increases; But face pressure again can not be too small, less than the liquid counterpressure between end face, then can push seal face open, causes leakage.And when as installed, must install according to given size of when design, but the difficult control of the size of rotating ring, so this brings very big trouble to installation process, neither be very desirable even install the back sealing effect, the requirement when not reaching design.
