    • 专利摘要:
    The stationary sliding ring seal is used for the rotating shaft of especially pipeline pumps. The sliding ring is pressed against a ring rotating with the shaft and a secondary shield is provided. This arrangement ensures long life for the seal system and facilitates inspection of the wear condition. This arrangement is especially used to prevent sparking in the large pipeline pumps. The housing cover has at its inlet groove a replaceable deflector plate. The spring system is arranged outside the pump housing. A gap is formed between the spring support plate and the outside end face of the guide sleeve of the seal system.

    专利说明:

    The invention relates to a sealing technique, in particular to contact annular seals for sealing media and substances on rotating shafts of aggregates, preferably petroleum pumps.
    The purpose of the invention is to increase reliability by protecting oil pumps from sparking and jet wear of sliding surfaces.
    Fig, 1 shows the mechanical seal, section; FIG. 2, a reflector plate with the direction of flow of the cooling medium,
    The mechanical seal contains a rotary sealing ring 1, fixed in the sealing sleeve 2 by means of pins 3 and sealed by a secondary seal in the circular ring 4, the sealing sleeve 2 is mounted on the shaft 5 and is supported on it through two ring-shaped supports and the seal relative to the shaft 5 through round ring b,
    The sleeve 2 is fixed through the passage hole 7 and the holes 8 threaded in the clamping ring 9 by clamping the clamping screws 10 on the free r rotating member 11 of the shaft. The guide sleeve 12 is fixedly mounted in the rim 13 of the housing 14 and sealed to the outer diameter by a circular ring 15.
    Seal ring 16 is installed with pressure in cup 17, sliding axially in guide sleeve 12 and sealed round the outer diameter with ring ring 18 and support ring 19. Radial protection of tension on non-rotating seal ring 16 is provided with spacer bolts 20, located S plate 21. Finding idaez in the guide sleeve 12 pins 22
    take with axial sliding the spring plate 21, prevent it from rotating together, and limit the distance of the spring system consisting of the plate 21 located in the blind holes 23 of the pressure springs 24 and the annular disk 25, the protection of the annular disk 25 is carried out by safety discs 26, at the same time limiting the course of the pressure springs 24.
    The required pre-clamping of the rotating rotary sealing ring is carried out outside the unit by fixing the gaps 33 and 34 between the guide sleeve 12 and the lid 1.3, as well as the plate 21 by means of the mounting plate 27.
    In order to cool the sliding surfaces, a pipe 28 is provided in the housing cover 13 for a cooling medium passing through the annular cavity — notch 29. At the entrance to the notch 29, a removable reflective cover (shield) 30 is fixedly mounted, refracting the direct pressure jet of the cooling medium and providing a uniform radial washer over the slide gussets.
    Additional adjustment of the face deviation of the rotating sealing ring 1 is performed externally by adjusting screws 31 screwed into the threaded holes of the clamping ring 9, in which they are pressed against the sleeve 2 and secured by a lock nut 32.
    The gap 33 between the guide sleeve 12 and the plate 21 serves to measure the wear of a pair of friction rings after removing the mounting template.
    The annular gap 34 formed. With spring plate 21 and spring wild 25, it provides non-blocking insertion of a non-rotating sealing ring.
