Technical field
The utility model relates to a kind of coal washery filter press mechanically-sealing apparatus.
Background technology
At present, the filter press of prior art is with the general moving ring assembly of mechanically-sealing apparatus, static components, spring, spring base, seal receptacle and the axle sleeve of close-fitting on pump shaft; Described moving ring assembly is connected with axle sleeve; Described static components is connected with seal receptacle; Described spring withstands between spring base and the throw-out collar usually; Described spring base all needs to be connected with the pump housing when mechanical seal is used with seal receptacle.Though the mechanically-sealing apparatus of said structure has the better seal performance; but also there is a weak point in it; be that spring base phenomenon improperly occurs installing through regular meeting in installation process, thereby influence the elastic compensating performance in the mechanical seal, reduce the stability of mechanical seal greatly.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of spring base to need not to be installed on the pump housing, thereby effectively guarantee the elastic compensating performance, the filter press mechanically-sealing apparatus of raising job stability.
For solving the problems of the technologies described above, the utility model provides a kind of filter press mechanically-sealing apparatus with following structure: it comprises moving ring assembly, static components and is used for axle sleeve with the pump shaft close-fitting; Described static components comprises seal receptacle, throw-out collar, spring and spring base; Described moving ring assembly is connected with axle sleeve; Described seal receptacle is connected with pump cover; Described stationary ring is installed in the stationary seat right-hand member; Described stationary seat and seal receptacle close-fitting; Described throw-out collar is connected with stationary seat; Described spring withstands between spring base and the throw-out collar; Described spring base is connected with seal receptacle by long spiro nail.
After adopting said structure, utility model has the following advantages: compared with prior art, because the spring base described in the utility model is connected with seal receptacle, thereby make that spring base need not to be connected with the pump housing again in installation process of the present utility model, thereby imitate the elastic compensating performance that guarantees mechanical seal, improved job stability of the present utility model.
As a kind of improvement, also clamping ring and latch can be set between pump cover described in the utility model and the seal receptacle; Described latch one end can be connected with seal receptacle, and its other end can be positioned at the lock pin aperture that is located on the pump cover; Described clamping ring can be fixed on the seal receptacle by screw.The clamping ring and the latch that increase can improve resistance to shock of the present utility model, thereby have improved job stability of the present utility model.
