Description
Technical field
The utility model relates to a kind of horizontal mechanical sealing mechanism, belongs to technical field of mechanical.
Background technique
Mechanical seal is a kind of gland seal device of rotating machinery, such as, and the equipment 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 transmission shaft and equipment, medium in equipment is by this gap to outward leakage, if equipment internal pressure is lower than barometric pressure, then air is revealed in equipment, therefore, one must be had to stop the gland seal device revealed.Existing mechanical seal device complex structure, install loaded down with trivial details, sealing effect is poor, thus causing trouble rate is higher.
Model utility content
For above-mentioned defect, it is simple that the purpose of this utility model is to provide a kind of structure, and easy for installation, sealing effect is high, a kind of horizontal mechanical sealing mechanism of failure rate is low.
The technological scheme that the utility model adopts for this reason is:
Comprise the transmission shaft stretched in tank body, on transmission shaft, cover has rotating ring, described rotating ring overcoat has stationary seat, described stationary seat lower end is provided with in-flanges, the stationary ring be seated on in-flanges is provided with between described stationary seat inwall and rotating ring outer wall, described stationary ring upper end is provided with seal end plate, described seal end plate upper end is provided with gland, described gland external peripheral surface is provided with outside thread, described outside thread is connected with the internal thread of stationary seat inwall upper end, some bearing pins are evenly provided with around the center hole of described seal end plate, on described bearing pin, cover has spring, the circumference overcoat that described some springs surround has a fixed cover, described fixed cover upper end is provided with connecting plate, described connecting plate is fixedly connected with gland by bolt, the outer wall of described stationary seat is provided with flange, described flange is connected with the adpting flange of tank end, O RunddichtringO I is provided with between the upper and lower two ends of inwall of described rotating ring and transmission shaft, described rotating ring upper end outer wall cover has connecting ring.
Further, described stationary ring and be respectively equipped with O RunddichtringO II between stationary seat inwall and rotating ring outer wall.
Further, the upper and lower two ends of described stationary ring are respectively equipped with locating stud, and the upper-end surface of described seal end plate lower end surface and stationary seat in-flanges is respectively equipped with positioning hole and matches with locating stud.
Further, O RunddichtringO III is provided with between described flange lower end surface and adpting flange upper-end surface.
The utility model has the advantages that:
The utility model structure is simple, more convenient in installation process, by setting up O RunddichtringO between each surface of contact, makes good sealing effect, thus reduces rate of breakdown.
