Description
Technical field
The utility model relates to the mechanically-sealing apparatus of mechanically-sealing apparatus, particularly nuclear power condensate pump.
Background technology
Sealing device that prior art nuclear power condensate pump uses as shown in Figure 1, include moving ring assembly, static components,
Axle sleeve, gland composition, moving ring assembly is by rotating ring, rotating seat, spring case tailstock, rotating ring counterbalance spring, rotating ring auxiliary seal ring, bullet
Trundle between spring box tailstock and rotating seat, be arranged on the transmission holding screw coordinated on spring case tailstock with axle sleeve and form, and moves
Ring assemblies are installed on axle sleeve and are rotated with axle sleeve；Static components are by the stop pin between stationary ring, stationary ring and gland, stationary ring sealing ring group
Into stationary ring coordinates with gland to be fixedly connected.
Requirement of the nuclear power condensate pump for mechanical seal is that to have high reliability, need to be run under multi-state point.
Above-mentioned prior art nuclear power condensation water mechanical sealing device used for pump, rotating ring is as ring is compensated, since its structural member is more,
